2006-02-20 Marius Vollmer From Mikael Djurfeldt : * random.c: Test for SCM_HAVE_T_UINT64 instead of SCM_HAVE_T_INT64. (scm_i_uniform32, scm_i_uniform32, scm_i_init_rstate): Use scm_t_uint64 and scm_t_uint32 instead of scm_t_int64 and scm_t_int32. 2006-02-14 Ludovic Courtès * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of LEN. Without this, too much collectable memory gets unregistered, which results in an underflow of SCM_MALLOCATED in `decrease_mtrigger()'. * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or equal to SCM_MALLOCATED. 2006-02-13 Marius Vollmer * eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock oinstead of scm_dynwind_pthread_mutex_lock so that it works when configured --without-threads. (SCM_APPLY, CEVAL): Likewise. Thanks to Han-Wen Nienhuys! 2006-02-12 Marius Vollmer * unif.c (scm_dimensions_to_uniform_array): Use the prototype for filling when the fill parameter is omitted, as documented, but turn #\nul into 0 since s8 arrays (signified by a #\nul prototype) can not store characters. 2006-02-09 Neil Jerram * socket.c (scm_c_make_socket_address): Pass address_size pointer on to scm_fill_sockaddr call. 2006-02-04 Neil Jerram * throw.h (scm_c_catch, scm_c_with_throw_handler, scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New. * throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New. (struct pre_unwind_data): New, replaces struct lazy_catch. (scm_c_catch): New, replaces scm_internal_catch as the primary catch API for C code; adds pre-unwind handler support. (scm_internal_catch): Now just a wrapper for scm_c_catch, for back compatibility. (tc16_pre_unwind_data, pre_unwind_data_print, make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from "lazy_catch" equivalents. (scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch as the primary C API for a "lazy" catch. (scm_internal_lazy_catch): Now just a wrapper for scm_c_with_throw_handler, for back compatibility. (scm_catch_with_pre_unwind_handler): Renamed from scm_catch; adds pre-unwind handler support. (scm_catch): Now just a wrapper for scm_catch_with_pre_unwind_handler, for back compatibility. (scm_with_throw_handler): New. (scm_lazy_catch): Update comment to say that the handler can return, and what happens if it does. (toggle_pre_unwind_running): New. (scm_ithrow): When identifying the throw target, take running flags into account. In general, change naming of things from "lazy_catch" to "pre_unwind". When throwing to a throw handler, don't unwind the dynamic context first. Add dynwind framing to manage the running flag of a throw handler. If a lazy catch or throw handler returns, rethrow the same exception again. Add pre-unwind support to the normal catch case (SCM_JMPBUFP). * root.c (scm_internal_cwdr): Add NULL args to scm_i_with_continuation_barrier call. * dynwind.c: Change comment mentioning lazy-catch to mention pre-unwind data and throw handler also. * continuations.h (scm_i_with_continuation_barrier): Add pre-unwind handler args. * continuations.c (scm_i_with_continuation_barrier): Add pre-unwind handler args, and pass on to scm_c_catch (changed from scm_internal_catch). (c_handler): Remove scm_handle_by_message_noexit call. (scm_c_with_continuation_barrier): Call scm_i_with_continuation_barrier with scm_handle_by_message_noexit as the pre-unwind handler. (scm_handler): Remove scm_handle_by_message_noexit call. (s_scm_with_continuation_barrier): Call scm_i_with_continuation_barrier with scm_handle_by_message_noexit as the pre-unwind handler. 2006-02-04 Kevin Ryde * gc-mark.c (scm_mark_all): Fix c99-isms "loops" and "again" variables. 2006-02-03 Kevin Ryde * list.c, list.h (scm_list): Restore this function for use from C. It's a complete no-op but in theory might used by someone. 2006-01-30 Marius Vollmer * eval.c (scm_eval_body): Lock source_mutex with a dynwind context so that it gets unlocked in all cases. (SCM_APPLY, CEVAL): Likewise. 2006-01-29 Marius Vollmer * ramap.c: (scm_array_map_x): Don't use scm_array_p, use scm_is_typed_array instead. Renamed the "frames" that are related to dynamic-wind to "dynamic contexts. Renamed all functions from scm_frame_ to scm_dynwind_. Updated documentation. Disabled "futures": * futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif". * eval.c, init.c: Comment out all 'future' related things. 2006-01-28 Marius Vollmer * inline.h, pairs.c (scm_is_pair): Moved scm_is_pair from pairs.c to inline.h to make it inline. 2005-12-19 Ludovic Courtès * strings.c (scm_i_take_stringbufn): New. (scm_i_c_take_symbol): New. (scm_take_locale_stringn): Use `scm_i_take_stringbufn ()'. * strings.h (scm_i_c_take_symbol): New. (scm_i_take_stringbufn): New. * symbols.c (lookup_interned_symbol): New function. (scm_i_c_mem2symbol): New function. (scm_i_mem2symbol): Use `lookup_symbol ()'. (scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'. This avoids creating a new Scheme string. (scm_from_locale_symboln): Likewise. (scm_take_locale_symbol): New. (scm_take_locale_symboln): New. * symbols.h (scm_take_locale_symbol): New. (scm_take_locale_symboln): New. 2006-01-18 Han-Wen Nienhuys * gc-card.c ("sweep_card"): don't count scm_tc_free_cell for free_count. 2005-11-29 Han-Wen Nienhuys * regex-posix.c (s_scm_regexp_exec): list the offending pattern upon error 2005-12-29 Neil Jerram * fluids.c (next_fluid_num): [From Ludovic Courtès:] Don't trigger the GC when allocated_fluids_len is zero. 2005-12-14 Neil Jerram * load.c (the_reader, the_reader_fluid_num): New. (scm_primitive_load): Support custom reader. (scm_init_load): Init the_reader and the_reader_fluid_num; export the_reader as `current-reader'. * scmsigs.c (do_read_without_guile): Use the "raw_data" passed in (rather than an uninitialized pointer on the stack). 2005-12-07 Marius Vollmer Reported by Bruce Korb: * init.c (invoke_main_func): Don't call exit here. Throws that are only caught by scm_with_guile will bypass us and would cause scm_boot_guile to return erroneously. (scm_boot_guile): Expect scm_with_guile to return and call exit here, passing it an appropriate exit code. From Andy Wingo: * script.c (scm_find_executable): Compile fix -- fgetc returns an unsigned char cast to an int, or -1 for EOS. 2005-12-06 Marius Vollmer * srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer non-const. (scm_take_u8vector, etc): Likewise. Thanks to Ludovic Courtès! * threads.h, threads.c (scm_t_guile_ticket, scm_leave_guile, scm_enter_guile): Removed from public API. See comment at scm_without_guile for the rationale. * scmsigs.c (read_without_guile): New. (signal_delivery_thread): Use it instead of scm_leave_guile/read/scm_enter_guile. From Stephen Compall: * eval.c (scm_m_cond): Recognize SRFI 61 cond syntax. (CEVAL): Evaluate SRFI 61 cond clauses. 2005-12-06 Ludovic Courtès * gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL. This was typically hit when running `gc-live-object-stats' right after starting Guile. 2005-11-30 Kevin Ryde * srfi-13.c (scm_string_append_shared): No copying if just one non-empty string in args. 2005-11-26 Kevin Ryde * gc-mark.c (scm_mark_all): Change C++ comment to C comment. Reported by Ludovic Courtès. * list.c (list): Should be "primitive" in SCM_SNARF_DOCS, not "register". * random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for scm_malloc returning NULL, it never does that. * putenv.c (putenv): Likewise. * socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is much too big to want to inline. 2005-11-17 Ludovic Courtès * print.c (EXIT_NESTED_DATA): Before popping from the stack, reset the value at its top. This fixes a reference leak. (PUSH_REF): Perform `pstate->top++' after calling `PSTATE_STACK_SET ()' in order to avoid undesired potential side effects. 2005-11-12 Ludovic Courtès * gc.c (scm_weak_vectors): Removed. 2005-11-12 Kevin Ryde * socket.c (scm_setsockopt): Missing @defvar in docstring. Reported by Ludovic Courtès. 2005-11-07 Marius Vollmer * stime.c (scm_mktime): Use scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START/END since the code inside the critical section might exit non-locally. 2005-11-04 Neil Jerram * eval.c (sym_instead): New symbol. (ENTER_APPLY): Remove optional use of a continuation when making trap call. (scm_debug_opts): Change doc for 'cheap option to make clear that it is now obsolete. (CEVAL, SCM_APPLY): Remove optional use of a continuation when making trap calls, and implement substitution of eval expressions and return values using the values that the trap call handlers return. * debug.h (SCM_CHEAPTRAPS_P): Removed. 2005-10-27 Ludovic Courtès * socket.c (scm_fill_sockaddr): No need to check NULL from scm_malloc. (scm_connect, scm_bind, scm_sendto): Accept sockaddr object. (scm_addr_vector): Renamed to _scm_from_sockaddr, update usages. (scm_from_sockaddr, scm_to_sockaddr, scm_make_socket_address, scm_c_make_socket_address): New functions. * socket.h: Add prototypes. 2005-10-24 Kevin Ryde * socket.c (scm_init_socket): Add IPPROTO_IP, IPPROTO_TCP, IPPROTO_UDP. Remove SOL_IP, SOL_TCP, SOL_UDP. The former are in POSIX spec examples, the latter are not available on for instance NetBSD. * socket.c (scm_getsockopt, scm_setsockopt): Update docstrings from posix.texi. * stime.c (scm_strftime): Update docstring from posix.texi. 2005-10-23 Marius Vollmer PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP is not portable enough. * null-threads.h, pthread-threads.h (SCM_I_PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Removed. (scm_i_pthread_mutexattr_recursive): New. * threads.c (scm_i_pthread_mutexattr_recursive): Declare. (scm_i_critical_section_mutex): Do not initialize statically. (scm_threads_prehistory): Initialize scm_i_pthread_mutexattr_recursive and scm_i_critical_section_mutex here. * eval.c (source_mutex): Do not initialiaze statically. (scm_init_eval): Do it here, using scm_i_pthread_mutexattr_recursive. 2005-09-05 Marius Vollmer * print.h (SCM_PRINT_KEYWORD_STYLE_I, SCM_PRINT_KEYWORD_STYLE): New. (sym_reader): New. (scm_print_opts): Added "quote-keywordish-symbols" option. (quote_keywordish_symbol): New, for evaluating the option. (scm_print_symbol_name): Use it. (scm_init_print): Initialize new option to sym_reader. 2005-08-15 Neil Jerram * eval.c (eval_letrec_inits): New. (CEVAL): Eval letrec initializer forms using eval_letrec_inits. 2005-08-12 Marius Vollmer * numbers.c: Use scm_from_bool instead of SCM_BOOL. Thanks to Peter Gavin! 2005-08-12 Kevin Ryde * srfi-13.c (scm_string_for_each_index): Correction to docstring. 2005-08-06 Kevin Ryde * srfi-13.c (scm_string_any, scm_string_every, scm_string_tabulate, scm_string_trim, scm_string_trim_right, scm_string_trim_both, scm_string_index, scm_string_index_right, scm_string_skip, scm_string_skip_right, scm_string_count, scm_string_map, scm_string_map_x, scm_string_for_each, scm_string_for_each_index, scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for procedures called in loops. 2005-08-02 Kevin Ryde * strports.c (st_flush): Increase buffer by 1.5x when growing, to avoid lots of copying where previoulsy growing by only 80 bytes at a time. 2005-08-01 Marius Vollmer * modules.h, modules.c (scm_eval_closure_module): Removed, we already have scm_lookup_closure_module, which does the same thing. 2005-08-01 Marius Vollmer New marking algorithm for weak hashtables that fixes the problem that references from the non-weak value to the associated weak key (for example) would prevent the entry from ever being dropped. Guardians have been changed back to their original semantics and are no longer greedy and no longer drop cycles. * gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak hashtable and guardian machinery but call the relevant functions directly. * guardians.h, guardians.c, deprecated.h, deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p, scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie): Deprecated and moved into deprecated.[ch]. * guardians.h, guardians.c: Mostly rewritten. (scm_i_init_guardians_for_gc, scm_i_identify_inaccessible_guardeds, scm_i_mark_inaccessible_guardeds): New. (scm_make_guardian): Removed greedy_p argument. * weaks.h, weaks.c (SCM_I_WVECT_TYPE, SCM_I_SET_WVECT_TYPE): New. (SCM_I_WVECT_N_ITEMS, SCM_I_SET_WVECT_N_ITEMS): New. (SCM_WVECTF_NOSCAN, SCM_WVECT_NOSCAN_P): Removed. (scm_weaks_prehistory): Removed. (scm_i_init_weak_vectors_for_gc, scm_i_mark_weak_vector, scm_i_mark_weak_vectors_non_weaks, scm_i_remove_weaks_from_weak_vectors, scm_i_remove_weaks): New. (scm_weak_vector_gc_init, scm_mark_weak_vector_spines, scm_scan_weak_vectors): Removed. * hashtab.h (scm_i_scan_weak_hashtables): New. * hashtab.c (make_hash_table, scm_i_rehash): Do not use SCM_WVECTF_NOSCAN. (hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of t->n_items. (scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former to latter. Do not scan the alists themselves, this is done by the weak vector code now. Just update the element count. * vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former to latter. The type is now only part of the cell word. (SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise. * init.c (scm_i_init_guile): Do not call scm_weaks_prehistory. 2005-07-18 Mikael Djurfeldt Some changes towards making it possible to run Guile on the EM64T platform. * gc.c (scm_gc_stats): Bugfix: Measure size of the type we are mallocating for (unsigned long *bounds). * hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to scm_t_bits before storing them in the type word. * gc.c (tag_table_to_type_alist): Modified type of c_tag from scm_t_bits to int. 2005-07-12 Kevin Ryde * eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy. * pairs.c (scm_error_pair_access): Use scm_from_locale_string rather than scm_makfrom0str. Reported by Ken Raeburn. * gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when returning SCM_GC_CARD_BVEC. * pairs.c (scm_error_pair_access): Plain ascii ' in error message rather than latin-1 acute accent, the latter may not print on all terminals. * srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and trailing deletions, so as to return a substring if those are the only changes. 2005-07-10 Kevin Ryde * socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8 for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*. (scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*. 2005-07-01 Han-Wen Nienhuys * gc-card.c (scm_i_card_statistics): init tag. * gc.c (tag_table_to_type_alist): check type of tag. Should be integer. 2005-06-18 Han-Wen Nienhuys * fports.c (s_scm_open_file): add the b flag for binary to the doc string. 2005-06-25 Kevin Ryde * srfi-13.c (scm_string_filter, scm_string_delete): Partial revert last change, use plain copy-on-write substrings, the individual descriptions in the srfi don't mention shared storage (only the introduction does). * strings.c (scm_take_locale_stringn): Use realloc to make room for null-terminator, rather than mallocing a whole new block. (scm_take_locale_string): Use scm_take_locale_stringn len==-1. 2005-06-12 Marius Vollmer * ramap.c (scm_array_index_map_x): First test for real arrays, then check for generalized vectors. This ensures that the generalized vector case need only work with zero-origin ranges. (scm_ra_eqp, scm_ra_compare): Use the new array handle functions to access the target array, making these functions work with all kinds of arrays, not just bit arrays. * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c: Deprecated everything. * environments.c (environment_default_folder, environment_default_observer): Do not use gh_call3, gh_call1. 2005-06-10 Han-Wen Nienhuys * modules.c (s_scm_eval_closure_module): new function. Return the module inside an eval-closure. * gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash table. This means that procedure properties are GC'd if the procedure dies. 2005-06-11 Kevin Ryde * srfi-13.c (scm_string_filter, scm_string_delete): For char and charset cases, count chars kept and build a string in a second pass, rather than using a cons cell for every char kept. Use a shared substring when nothing removed (such sharing is allowed by the srfi). 2005-06-09 Han-Wen Nienhuys * gc.c (tag_table_to_type_alist): convert tag number to "tag %d" string, so live object stats can be sorted with string * print.c (iprin1): When writing a string, collect all characters that can be printed directly into one call to scm_lfwrite. Previously, every character was output with its own call to write(2) on unbuffered ports. * eval.c (scm_eval_options_interface): Use scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START and SCM_CRITICAL_SECTION_END. * unif.c (scm_array_in_bounds_p): First test for real arrays, then check for generalized vectors. This ensures that the generalized vector case need only work with zero-origin ranges. 2005-06-06 Kevin Ryde * srfi-13.c (scm_string_split): Compare char/char in scan. Mixing an unsigned int SCM_CHAR and a char string meant an 8-bit char was never matched. 2005-06-05 Marius Vollmer * eval.c: Added comment on how to make case 1.1 of r5rs_pitfall.test succeed. From Jan Nieuwenhuizen . Thanks! * hashtab.h: Bugfix: use SCM_API (WAS: extern). * socket.c: Remove obsolete comment about socklen_t. (s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code. * numbers.h (isnan)[__MINGW32__]: Remove. * Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add DEFAULT_INCLUDES when cross compiling. * threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines. * stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS. (Changed slightly from Jan's patch.) 2005-05-22 Marius Vollmer * unif.c (scm_make_shared_array): Add old base to new base since scm_array_handle_pos does not include the base. (scm_aind): Likewise. * ports.c (scm_putc, scm_puts): Assert that the port argument is a output port. 2005-05-12 Neil Jerram Mac OS X compile warning fixes, reported by Richard Todd. * unif.c (scm_i_read_array): Declare rank as ssize_t, to guarantee that it is signed. * strports.c (st_resize_port): Add unsigned char cast. (scm_mkstrport): Make read/write_buf cast unsigned. * srfi-13.c (string_titlecase_x): Add unsigned char cast. * rdelim.c (scm_read_line): Initialize slen. * load.c (scm_search_path): Remove weird >=1, and add parentheses to clarify conditions. * hash.c (scm_hasher): Add const unsigned char cast. * gh_data.c (gh_chars2byvect): Add scm_t_int8 cast. 2005-05-11 Neil Jerram Fix C99isms reported by Ludovic Courtès: * threads.c (s_scm_lock_mutex): Don't declare msg in middle of code. * gc.c (s_scm_gc_live_object_stats): Don't declare alist in middle of code. * gc-card.c (scm_i_card_statistics): Don't declare tag in middle of code. (scm_i_card_statistics): Add block for declarations of tag_as_scm and current. 2005-05-10 Neil Jerram * scmsigs.c (signal_delivery_thread): Return a value, to avoid compile warning reported by Werner Scheinast. 2005-04-30 Han-Wen Nienhuys * list.h: remove scm_list() * fluids.c (DYNAMIC_STATE_NEXT_LOC): new macro for use with SCM_DEBUG_CELL_ACCESSES (FLUID_NEXT_LOC): idem. 2005-04-30 Kevin Ryde * numbers.c (scm_divide): Correction to 1/complex and /complex, need to test abs(re) * ramap.c (scm_array_map_x): Allow no source args, add num args checks to subr_1, subr_2, subr_2o and dsubr cases. No source args only has a few sensible uses (like filling with a random number generator say), but has been allowed in the past and so should be kept. 2005-04-23 Kevin Ryde * hashtab.c (scm_hashx_remove_x): Need to pass "closure" to scm_hash_fn_remove_x. * list.c (scm_cons_star): Don't modify the rest list, it belongs to the caller when cons* is reached through apply. * list.c (list): Use scm_list_copy, so as to produce a fresh list when list is called using apply, under the debugging evaluator. (scm_list): Remove. * list.c, list.h (scm_make_list): New code, moving make-list from boot-9.scm. 2005-04-14 Kevin Ryde * numbers.c, numbers.h (scm_oneplus, scm_oneminus): New functions, converted from scheme code in boot-9.scm. 2005-04-11 Kevin Ryde * srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared): Validate list argument, scm_string_append and scm_string_append_shared don't do that to their rest argument (in a normal build). 2005-04-04 Marius Vollmer * hashtab.h, hashtab.c (scm_t_hashtable): Removed 'closure' field. The closure can not be stored since it is no longer valid at GC time. (make_hash_table): Initialize 'hash_fn' field. (scm_i_rehash): Only store hash_fn in hash table when closre is NULL. (rehash_after_gc): Only call scm_i_rehash when 'hash_fn' is non-NULL. Always use a NULL closure. (scm_hash_fn_create_handle_x): Also rehash when table contains too few entries. 2005-03-29 Marius Vollmer * hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn argument; always use scm_delq_x. The delete_fn function works on the handle, not the key, and it therefore makes no sense to make it configurable. Changed all callers. (scm_hashx_remove_x): Likewise. Also, exported to Scheme. (scm_hash_clear): Accept plain vectors as hashtables. (scm_delx_x): Removed. 2005-03-28 Han-Wen Nienhuys * inline.h (scm_double_cell): use __asm__ iso. asm, to maintain compatibility with gcc -std=c99. 2005-03-24 Mikael Djurfeldt * async.h (scm_mask_ints): Removed left over reference to scm_root. * threads.c: Removed fprintf debug statements. 2005-03-24 Neil Jerram * debug.c (scm_make_memoized): Restore use of SCM_UNPACK. 2005-03-23 Neil Jerram * debug.c (scm_make_memoized): Remove unnecessary critical section, and simplify by using SCM_RETURN_NEWSMOB. 2005-03-20 Mikael Djurfeldt * strings.h (SCM_STRING_UCHARS): Added missing argument. 2005-03-18 Kevin Ryde * arbiters.c (FETCH_STORE) [generic C]: Should be scm_i_scm_pthread_mutex_lock/unlock now. Reported by Ludovic Courtès. 2005-03-13 Kevin Ryde * numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in srfi-60. * numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand, because OR-ing bits into a negative can reduce the value to an inum. * numbers.c (scm_num_eq_p): On 64-bit systems, be careful about casting inum to double since that can lose precision. 2005-03-10 Marius Vollmer * threads.h, threads.c (scm_i_thread): Added gc_running_p field. (guilify_self_1): Initialize it. * gc.h, gc.c (SCM_FREECELL_P): Removed for good. (scm_block_gc, scm_gc_heap_lock): Removed. Removed all uses. (scm_gc_running_p): Now a macro that refers to the scm_i_thread field. (scm_i_sweep_mutex): Now a non-recursive mutex. GC can not happen recursively. (scm_igc, scm_i_gc): Renamed former to latter. Changed all uses. Do not lock scm_i_sweep_mutex, which is now non-recursive, or set scm_gc_running_p. Do not run the scm_after_gc_c_hook. (scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the scm_after_gc_c_hook here.

Do not call scm_i_read_homogenous_vector, since that is also handled by scm_i_read_array now. 2004-10-27 Marius Vollmer First cut at integrating uniform vectors from srfi-4 with the rest of Guile. This change replaces scm_tc7_byvect with a s8 uniform vector. The plan is to gradually replace one type after the other until none is left and then to consider general cleanups and optimizations. * srfi-4.h, srfi-4.i.c (scm_u8vector_elements, etc): New. * srfi-4.h, srfi-4.c (scm_uniform_vector_p, scm_uniform_vector_ref, scm_uniform_vector_set_x, scm_uniform_vector_to_list, scm_is_uniform_vector, scm_c_uniform_vector_lengths, scm_c_uniform_vector_size, scm_uniform_vector_elements, scm_uniform_vector_element_size, scm_uniform_vector_release): New.

(alloc_uvec): Use it. * srfi-4.h, srfi-4.i.c (scm_take_u8vector, etc): New. * random.c (vector_scale, vector_scale_x): Renamed former to the latter, since it modifies its argument. (vector_scale_x, vector_sum_squares, scm_random_normal_vector_x): Do not use scm_universal_vector_length for non-uniform vectors. Use scm_f64vector_elements to access innards of uniform vectors. * convert.i.c: Convert srfi-4 style uniform vectors when requested. * convert.c (scm_c_scm2chars, scm_c_chars2scm, scm_c_chars2byvect): Use a s8vector instead of a scm_tc7_byvect. 2004-10-26 Marius Vollmer * numbers.h, numbers.c (scm_i_print_double): New. * srfi-4.c, srfi-4.h, srfi-4.i.c: New files, initially from ../srfi/ but heavily modified. * Makefile.am: Add them in all the right places. * init.c (scm_init_guile_1): Call scm_init_srfi_4. * read.c (scm_lreadr): Call scm_i_read_homogenous_vector for '#f', '#u', and '#s'. * read.h, read.c (scm_i_input_error): Renamed from scm_input_error and made non-static.

Include instead of . 2004-10-20 Marius Vollmer * sort.c (quicksort): Copy pivot out of the array while constructing the partitions; it could get overwritten otherwise. Because of the ultimate insertion sort, this bug did not cause quicksort to fail, it just put all the burdon on the insertion sort and was thus very slow.

(scm_out_of_range, scm_out_of_range_pos, scm_wrong_type_arg, scm_wrong_type_arg_msg): Pass bad_value in rest argument of exception so that it gets highlighted in the backtrace. Don't talk about "argument" when not giving a position. * throw.c (handler_message): The rest argument is the fourth argument, not everything after the third. Call scm_display_backtrace_with_highlights, passing the rest argument when appropriate. 2004-09-22 Marius Vollmer From Jan Nieuwenhuizen and Bruno Haible : * i18n.c: Handle --disable-nls (thanks Bruno). * posix.c (scm_init_posix): Add LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT, LC_IDENTIFICATION. * i18n.c (scm_i_to_lc_category): New name and export.

(scm_c_load_extension): Use scm_from_locale_string instead of scm_makfrom0str. * fports.h, fports.c (scm_i_fdes_to_port): New, like scm_fdes_to_port, but take mode bits directly instead of as a C string. (scm_i_fdes_to_port): Implement using above. (scm_open_file): Use scm_i_fdes_to_port together with scm_i_mode_bits to avoid accessing internals of SCM string from C. * vports.c (scm_make_soft_port): Use scm_i_fdes_to_port together with scm_i_mode_bits to avoid accessing internals of SCM string from C. * ports.h (scm_i_mode_bits): New, same as scm_mode_bits but with a SCM string as argument. * ports.c (scm_i_void_port): New, like scm_void_port but take mode bits directly instead of C string. (scm_void_port): Implement using above. (scm_sys_make_void_port): Use scm_i_void_port together with scm_i_mode_bits to avoid accessing internals of SCM string. * strings.h, strings.c (scm_i_get_substring_spec): New. * socket.c, rw.c, deprecated.h, validate.h (SCM_VALIDATE_STRING_COPY): Deprecated. Replaced all uses with SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or scm_to_locale_string, etc. (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Deprecated. Replaced as above, plus scm_i_get_substring_spec. * regex-posix.c, read.c, random.c, ramap.c, print.c, numbers.c, hash.c, gc.c, gc-card.c, convert.i.c, backtrace.c, strop.c, strorder.c, strports.c, struct.c, symbols.c, unif.c, ports.c: Use SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first with more explicit scm_remember_upto_here_1, etc, or introduced them in the first place. * posix.c (WITH_STRING): New helper macro. Use it where one locale string is needed for a short piece of code. (STRING_SYSCALL): New helper macro. Use it instead of SCM_SYSCALL when one locale string is needed. (scm_mkstemp): Convert tmpl to a locale string. (scm_putenv): Rewritten to use only C strings. (scm_setlocale, scm_crpt): Convert argument strings to locale strings. 2004-08-11 Marius Vollmer * load.c (scm_primitive_load_path): Do not check for absolute filenames when scm_sys_search_load_path returns false, which will return absolute filenames unchanged. 2004-08-11 Marius Vollmer * gc.c, procprop.c (scm_init_storage, scm_stand_in_procs, scm_stand_in_proc): Use a hastable for scm_stand_in_procs instead of an alist. Thanks to Matthias Koeppe! 2004-08-10 Marius Vollmer * strings.h, deprecated.h (SCM_STRING_COERCE_0TERMINATION_X): Moved from string.h to deprecated.h. * deprecated.c, deprecated.h (SCM_CHARS, SCM_LENGTH): Removed. * strings.h, strings.c (SCM_MAKE_STRING_TAG): Renamed to SCM_I_MAKE_STRING_TAG, changed all uses. (SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH respectively. For a short time, the old names are still there as aliases. Not all uses have been changed yet, but the ones in strings.c have. (SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from SCM_T_BITS_MAX. (scm_is_string, scm_from_locale_string, scm_from_locale_stringn, scm_take_locale_string, scm_take_locale_stringn, scm_to_locale_string, scm_to_locale_stringn, scm_to_locale_stringbuf): New. (scm_c_string2str, scm_c_substring2str): Deprecated by moving to deprecated.[hc]. Implemented in terms of the new functions above. (scm_take_str, scm_take0str, scm_mem2string, scm_str2string, scm_makfrom0str): Reimplemented in terms of the new functions from above. They will be discouraged shortly. (scm_substring): Do not use scm_mem2string. (scm_i_allocate_string_pointers, scm_i_free_string_pointers): New, to replace similar code from posix.c, simpos.c, and dynl.c. (scm_string_append): Use memcpy instead of explicit loop. Do not use register keyword. Use plain 'char' instead of 'unsigned char'. * strports.c (scm_mkstrport): Use SCM_I_STRING_UCHARS instead of SCM_STRING_UCHARS. Use SCM_I_STRINGP instead of SCM_STRINGP. * strop.c (scm_i_index): Replaced SCM_STRINGP, SCM_STRING_CHARS, and SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and SCM_I_STRING_LENGTH, respectively. Pass string object directly, not as a pointer. Use scm_remember_upto_here_1 to protect it. * read.c (scm_input_error): Use a SCM value for 'fn', not a C string. This avoids a conversion round-trip. * gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and SCM_I_STRING_LENGTH, respectively. (gh_scm2newstr): Implement in terms of scm_to_locale_string. * environments.c: Instead calling scm_puts on the SCM_STRING_CHARS of a string, call scm_display on the string itself. * dynwind.c, dynwind.h (scm_frame_free): New. * stime.c, socket.c, simpos.c, procs.c, posix.c, ports.c, net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c: Replaced uses of SCM_STRING_CHARS with proper uses of scm_to_locale_string.

(scm_parse_path): Use scm_string_split to do the work. (scm_init_load_path): Use scm_parse_path instead of scm_internal_parse_path. (scm_search_path): Rewritten string handling part of the code in terms of scm_to_locale_stringbuf and so that it is thread safe. * error.c (scm_error_scm): Throw directly instead of calling scm_error, this avoids the back and forth conversion of SUBR and MESSAGE and also plugs a memory leak. (scm_error): Call scm_error_scm. * backtrace.c: Replaced SCM_STRINGP with scm_is_string. (display_header): Print FNAME when it is true, not merely when it is a string. * strings.h (SCM_SET_STRING_LENGTH, SCM_SET_STRING_CHARS): Removed unceremoniously. They were unused by Guile itself, and external use should stop immediately. 2004-08-10 Marius Vollmer * numbers.h, number.c, deprecated.h, deprecated.c (scm_round, scm_truncate): Renamed to scm_c_round and scm_c_truncate; deprecated versions installed in deprecated.h and deprecated.c. Changed all uses. 2004-08-06 Rob Browning * net_db.c (scm_resolv_error): don't cause an exception while trying to throw an exception -- call scm_misc_error with correct arguments. The previous arguments needed a format escape that wasn't in any of the format strings. 2004-08-06 Kevin Ryde * ramap.c (scm_array_fill_x): For byvect char fill, force signed char so as not to depend on signedness of plain char. For byvect range check, throw out-of-range rather than wrong-type-arg. * unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force signed byte range checks by using scm_to_schar and scm_from_schar, don't want to depend on signedness of C char. 2004-08-05 Kevin Ryde * arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of SCM_DEFER_INTS. (scm_release_arbiter): Use scm_i_misc_mutex so return value can be guaranteed if multiple threads compete to unlock. Update docstrings per doc/ref/api-scheduling.texi. * filesys.c (scm_copy_file): Use fstat on the input fd rather than stat on the filename, to be certain a file rename can't mean we get info on one filesystem object but open another. This fstat usage is similar to Emacs copy-file. * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi. * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on SIGINT and SIGQUIT, since those values are ints. 2004-08-03 Marius Vollmer * num2integral.i.c, num2float.i.c: Removed. * Makefile.am (noinst_HEADERS): Updated. * numbers.h. numbers.c (scm_make_ratio): Renamed to scm_i_make_ratio and made static, replaced uses with scm_divide.

(scm_to_double): Do not implement in terms of scm_num2dbl, use explicit code. (scm_from_double): Do not implement in terms of scm_make_real, use explicit code. 2004-08-02 Marius Vollmer * init.c (scm_init_guile_1): Call scm_i_init_discouraged. * gen-scmconfig.h.in (SCM_I_GSC_ENABLE_DISCOURAGED): New. * gen-scmconfig.c (SCM_ENABLE_DISCOURAGED): Emit based on above. * eval.c (SCM_EVALIM, SCM_EVALIM2, SCM_XEVAL, SCM_XEVALCAR): Renamed to SCM_I_* in order to avoid collisions with the versions defined in deprecated.h. * discouraged.h, discouraged.c: New files. * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_EQ_P, SCM_NEGATE_BOOL, SCM_BOOL, SCM_BOOT_NOT): Promoted from being deprecated to being discouraged by moving to discouraged.h. * numbers.h, numbers.c, discouraged.h, discouraged.c (scm_short2num, scm_ushort2num, scm_int2num, scm_uint2num, scm_long2num, scm_ulong2num, scm_size2num, scm_ptrdiff2num, scm_num2short, scm_num2ushort, scm_num2int, scm_num2uint, scm_num2long, scm_num2ulong, scm_num2size, scm_num2ptrdiff, scm_long_long2num, scm_ulong_long2num, scm_num2long_long, scm_num2ulong_long): Discouraged by moving to discouraged.h and discouraged.c and reimplementing in terms of scm_from_* and scm_to_*. Changed all uses to the new scm_from_* and scm_to_* functions. * numbers.h, numbers.c: Removed GUILE_DEBUG code. (scm_i_short2big, scm_i_ushort2big, scm_i_int2big, scm_i_uint2big, scm_i_size2big, scm_i_ptrdiff2big): Removed. (scm_i_long2big, scm_i_ulong2big): New, explicit definitions. * conv-integer.i.c, conv-uinteger.i.c: Use them instead of explicit code. 2004-08-02 Kevin Ryde * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Add comments about past and current usage and migration. 2004-07-31 Kevin Ryde * error.c (scm_strerror): Use scm_i_misc_mutex around strerror since it's not thread safe. (scm_syserror): Use scm_strerror rather than SCM_I_STRERROR, to take advantage of this. * fports.c (scm_open_file): Use scm_strerror likewise. * filesys.c (scm_stat, scm_lstat): Ditto. * filesys.c (scm_copy_file): Avoid fd leak when destination file cannot be opened. * symbols.c (scm_gensym): Use scm_i_misc_mutex around gensym_counter update, for thread safety. (gensym_counter): Move into scm_gensym which is its only user. (scm_init_symbols): No need to explicitly initialize gensym_counter. 2004-07-29 Marius Vollmer * numbers.h (scm_to_schar, scm_to_uchar, scm_to_char, scm_to_short, scm_to_ushort, scm_to_int, scm_to_uint, scm_to_long, scm_to_ulong, scm_to_long_long, scm_to_ulong_long, scm_to_intmax, scm_to_uintmax, scm_to_size_t, scm_to_ssize_t scm_from_schar, scm_from_uchar, scm_from_char, scm_from_short, scm_from_ushort, scm_from_int, scm_from_uint, scm_from_long, scm_from_ulong, scm_from_long_long, scm_from_ulong_long, scm_from_intmax, scm_from_uintmax, scm_from_size_t, scm_from_ssize_t): No longer defined in terms of scm_to_signed_integer, etc, but in terms of scm_to_int8, etc. * gen-scmconfig.c (SCM_SIZEOF_INTMAX, SCM_SIZEOF_SIZE_T): New. * gen-scmconfig.h.in: Removed SCM_I_GSC_*_LIMITS macros, they are no longer used. * __scm.h (SCM_I_UTYPE_MAX, SCM_I_TYPE_MAX, SCM_I_TYPE_MIN, SCM_I_SIZE_MAX, SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX): New. * __scm.h, gen-scmconfig.c (SCM_I_LLONG_MAX, SCM_I_LLONG_MIN, SCM_I_ULLONG_MAX, SCM_T_INT8_MIN, SCM_T_INT8_MAX, SCM_T_UINT8_MAX, SCM_T_INT16_MIN, SCM_T_INT16_MAX, SCM_T_UINT16_MAX, SCM_T_INT32_MIN, SCM_T_INT32_MAX, SCM_T_UINT32_MAX, SCM_T_INT64_MIN, SCM_T_INT64_MAX, SCM_T_UINT64_MAX, SCM_T_INTMAX_MIN, SCM_T_INTMAX_MAX, SCM_T_UINTMAX_MAX): Moved definition into __scm.h, using new SCM_I_TYPE_MIN, etc. * conv-integer.i.c, conv-uinteger.i.c: New files, used to generate the functions below. * Makefile.am (noinst_HEADERS): Added conv-integer.i.c and conv-uinteger.i.c. * numbers.c, numbers.h (scm_to_int8, scm_to_uint8, scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32, scm_to_int64, scm_to_uint64, scm_from_int8, scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32, scm_from_uint32, scm_from_int64, scm_from_uint64): Turned from macros into proper functions. (scm_to_signed_integer, scm_to_unsigned_integer, scm_from_signed_integer, scm_from_unsigned_integer): Generate via conv-integer.i.c and conv-uinteger.i.c, as well. * number.h (scm_to_ssize_t, scm_to_size_t): Use the new SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for the limits. Those are always defined. 2004-07-29 Kevin Ryde * posix.c (scm_ttyname): Use scm_i_misc_mutex for thread safety. 2004-07-28 Kevin Ryde * posix.c (scm_ctermid): Use an L_ctermid buf on the stack, for thread safety. * unif.c (scm_array_set_x): For svect, use scm_num2short for consistency with other vector types and to get arg and func name into error message. 2004-07-27 Marius Vollmer * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL): Reimplement using scm_is_false, scm_is_true, scm_is_bool, and scm_from_bool, respectively. (SCM_NINUMP): Added. * tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into deprecated.h. Replaced all uses with scm_is_eq. 2004-07-24 Kevin Ryde * threads.c, threads.h (scm_i_misc_mutex): New SCM_GLOBAL_MUTEX. * posix.c (scm_crypt): Use it to protect static data in crypt(). 2004-07-23 Marius Vollmer * deprecated.h, deprecated.c, numbers.h (SCM_INUMP, SCM_NINUMP, SCM_INUM): Deprecated by renaming them to SCM_I_INUMP, SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated versions to deprecated.h and deprecated.c. Changed all uses to either use the SCM_I_ variants or scm_is_*, scm_to_*, or scm_from_*, as appropriate. * dynwind.c (scm_i_dowinds): Removed unused code that would call the unexisting scm_cross_dynwind_binding_scope for inums on the windlist. 2004-07-10 Marius Vollmer * socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6 byte-wise address to a SCM integer. Changed all uses. (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to scm_to_ipv6 and added type and range checking, for converting from an IPv& byte-wise address to a SCM integer. Changed all uses. (bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function is now done by scm_to_ipv6. * numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot not accept inexact integers. * validate.h, deprecated.h (SCM_VALIDATE_INUM, SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT, SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY, SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF, SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE, SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the fixnum/bignum distinction visible. Changed all uses to scm_to_size_t or similar. 2004-07-09 Marius Vollmer * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM. 2004-07-10 Kevin Ryde * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather than size>=0, since 0<=hash * numbers.c (scm_is_signed_integer, scm_is_unsigned_integer): Rewritten using the same logic as scm_to_signed_integer and scm_to_unsigned_integer, respectively, which is better(tm). Also, use CHAR_BIT instead of hardcoding 8. (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used SCM_I_LLONG_MIN etc. instead. * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to SCM_I_MAKINUM and changed all uses. * deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated. * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX, SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute them by assuming twos-complement. 2004-07-07 Marius Vollmer * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that configure now produces. * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc definitions, giving the limits of the integer types defined by Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since LLONG_MIN or LONG_LONG_MIN is hard to get at. * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not SHORT_MIN. (scm_to_size_t): Use SIZE_MAX instead of cooking our own. (scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8, scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32, scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax, scm_from_long_long, scm_from_ulong_long, scm_from_int8, scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32, scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax, scm_from_uintmax): New. 2004-07-06 Marius Vollmer * tags.h (scm_is_eq): New. * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into "deprecated.h". Replaced all uses with scm_is_false, scm_is_true, scm_from_bool, and scm_is_bool, respectively. * boolean.h (scm_is_bool): Fix bug in prototype. (scm_from_bool): The argument is "x" not "f", stupid. * boolean.c (scm_is_bool): Fix typo. * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer, scm_is_unsigned_integer, scm_to_signed_integer, scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char, scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong, scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar, scm_from_char, scm_from_short, scm_from_ushort, scm_from_int, scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t, scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double): New. 2004-07-05 Marius Vollmer * boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool, scm_to_bool): New. 2004-06-27 Dirk Herrmann * backtrace.c (display_expression, display_frame): Call scm_i_unmemoize_expr for unmemoizing a memoized object holding a single memoized expression. * debug.c (memoized_print): Don't try to unmemoize the memoized object, since we can't know whether it holds a single expression or a body. (scm_mem_to_proc): Removed check for lambda expression, since it was moot anyway. Whoever uses these functions for debugging purposes should know what they do: Creating invalid memoized code will cause crashes, independent of whether this check is present or not. (scm_proc_to_mem): Take the closure's code as it is and don't append a SCM_IM_LAMBDA isym. To allow easier debugging, the memoized code should not be modified. * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed scm_unmemoize from public use, but made scm_i_unmemoize_expr available as a guile internal function instead. However, scm_i_unmemoize_expr will only work on memoized objects that hold a single memoized expression. It won't work with bodies. * debug.c (scm_procedure_source), macros.c (macro_print), print.c (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body, i. e. a list of expressions. * eval.c (unmemoize_exprs): Drop internal body markers from the output during unmemoization. * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr, scm_i_unmemocopy_body): Removed scm_unmemocopy from public use, but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available as guile internal functions instead. scm_i_unmemoize_expr will only work on a single memoized expression, while scm_i_unmemocopy_body will only work on bodies. 2004-06-21 Dirk Herrmann * eval.c (unmemoize_exprs): Handle semi-memoized code. (scm_cons_source, scm_primitive_eval): Prefer higher level predicate SCM_FALSEP over SCM_IMP. 2004-06-15 Rob Browning * script.c (scm_shell_usage): minor phrasing change. * gc_os_dep.c: update ifdefery for macosx. (scm_get_stack_base): separate result initialization from declaration to slience warnings with macosx and hp-ux using gcc 3.3. Thanks to Andreas Vögele. 2004-06-13 Han-Wen Nienhuys * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition. 2004-06-06 Dirk Herrmann * list.[ch] (scm_i_finite_list_copy): New internal function to copy lists that are known to be finite (though not necessarily proper). * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat a closure's argument list like an expression of a body. * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and, unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay, unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let, unmemoize_letrec, unmemoize_letstar, unmemoize_or, unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc, unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref, unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x, unmemoize_builtin_macro): New static functions and symbols. (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy now has a slightly different meaning: The memoized form that is receives as its argument is now interpreted as a sequence of expressions from a body. (unmemocar, scm_unmemocar): Since the whole functionality of unmemocar and scm_unmemocar is not needed any more, scm_unmemocar has its old content back and is deprecated, while unmemocar has been removed. (SCM_BIT7): Removed. (CEVAL): For unmemoizing a single expression, call unmemoize_expression instead of scm_unmemocopy, which now expects a sequence of body expressions. Eliminated unnecessary empty environment frame when executing let* forms. Eliminated unmemoization step from evaluator. 2004-06-02 Marius Vollmer * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to macroexp and made static. Added new version of scm_macroexp that emits a deprecation warning and then calls macroexp. (scm_m_undefine): Issue deprecation warning. 2004-05-30 Dirk Herrmann * eval.c (lookup_global_symbol, literal_p, try_macro_lookup): Modified to make set! work on symbols that represent syntactic keywords. 2004-05-26 Han-Wen Nienhuys * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent compound expression as lvalue errors. 2004-05-24 Marius Vollmer * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the WINDER_DATA to a SCM. 2004-05-24 Dirk Herrmann * goops.c (compute_getters_n_setters, create_standard_classes, scm_add_slot): Compute closures by calling scm_i_eval_x on a lambda expression rather than creating them with scm_closure. 2004-05-22 Dirk Herrmann * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for misplaced syntactic keywords. This will not work unless guile's defmacro feature is deprecated. (scm_m_case): Fixed a bug that caused the list of labels to grow with every case form. 2004-05-19 Kevin Ryde * numbers.c (scm_round_number): For inum and big, just return x. For real, use scm_round for 2^54-1 etc problems covered there. * numbers.c (trunc): Remove #define to scm_truncate when the C library doesn't provide trunc. This was for when `truncate' was done as a scm_tc7_dsubr, no longer required. * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction to stack marking call, two parameters and no cast on t->base. 2004-05-18 Marius Vollmer * hashtab.c (rehash_after_gc): Bug fix: properly link the processed hashtables back into the weak_hashtables list. Thanks to Bill Schottstaedt! 2004-05-16 Dirk Herrmann * eval.c (unmemoize_quote): New static function. (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code representation of 'quote' and '@slot-ref' to an improper list. This reduces execution time, the number of cells used to hold the memoized code, and thus also reduces garbage collection time. (scm_unmemocopy): Use unmemoize_quote for quote expressions. (SCM_CEVAL): Changed macro handling to also work with macros that return improper lists. Added an assertion, that the code returned by a macro transformer will not lead to cycles in the memoized code. 2004-05-15 Dirk Herrmann No functional change, just rearrangements of functions within the file. * eval.c (scm_ilookup, scm_unbound_variable_key, error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to the definitions used for execution, since that's where they will belong to later. 2004-05-15 Dirk Herrmann * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used throughout guile, has not been part of an official release yet, and the concept of sloppy predicates has never been a good idea. (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR, SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR): Simplified. 2004-05-15 Dirk Herrmann * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits to make explicit what happens. 2004-05-15 Dirk Herrmann * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make explicit what happens. * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than SCM_SET_CELL_WORD_x when writing scheme objets to cell elements. 2004-05-11 Marius Vollmer * scmsigs.c (scm_sigaction_for_thread): Validate that the handler is indeed a procedure when it isn't a number. 2004-05-10 Marius Vollmer Convert floating point numbers into strings with an arbitrary radix. Thanks to Richard Todd! * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will fit. (fx): Removed. (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix, number_chars): New, to support variable radices. (idbl2str): Use above instead of the old base-10 only tables. (iflo2str): Pass on new RADIX argument to idbl2str. (scm_number_to_string): Pass radix to iflo2str. (scm_print_real, scm_print_complex): Explicitly pass radix 10 to iflo2str. (scm_init_numbers): Call init_dblprec and init_fx_radix for all possible radices. 2004-05-10 Kevin Ryde * numbers.c (scm_logbit_p): Correction to test above the end of an inum. Reported by Jan Konecny. 2004-05-06 Marius Vollmer * gc.h (scm_t_cell): Fields are now of type SCM instead of scm_t_bits. Updated all users. (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of duplicating the code. (SCM_CELL_OBJECT_LOC): New. (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC. (SCM_CELL_WORD_LOC): Moved to "deprecated.h". * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS, SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS, SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3, SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3, SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC, SCM_SMOB_OBJECT_3_LOC): New. * smob.c (scm_i_set_smob_flags): New function. * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h, hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h, random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h: Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate. * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of taking the address of SCM_CELL_WORD_1, the latter being no longer an lvalue. * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead of casting SCM_CELL_WORD_LOC. 2004-05-02 Kevin Ryde * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under --disable-deprecated. Reported by Andreas Vögele. * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in particular on HP-UX). Reported by Andreas Vögele. * list.c (varargs.h): Remove, leave just stdarg.h which is all the code has support for. Fixes building with AIX cc, which is ansi but doesn't define __STDC__. Reported by Keith Crane. (var_start): Remove macro, this variation no longer required. (scm_list_n): Use va_start directly. 2004-05-01 Kevin Ryde * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which is now gone. Reported by Andreas Vögele. 2004-04-28 Kevin Ryde * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT, mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for ctype.h tests, to avoid warnings from gcc on HP-UX about char as array subscript. Reported by Andreas Vögele. Also cast through unsigned char to avoid passing negatives to those macros if input contains 8-bit values. * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case, corrections to range check for signed numbers. Remove scm_remember_upto_here_1(num) from these checks, since num is used subsequently anyway. * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to avoid warning from gcc 3.4. Reported by Hyperdivision. * numbers.c (scm_bit_extract): Use min instead of MIN. (MIN): Remove, this conflicts with similar macro defined by limits.h on HP-UX. Reported by Andreas Vögele. * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in particular on HP-UX). Reported by Andreas Vögele. * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t. Reported by Andreas Vögele. * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long), for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported by Andreas Vögele. 2004-04-22 Dirk Herrmann * eval.c (s_macro_keyword): New static identifier. (scm_m_define): Change order to first create binding and evaluating the expression afterwards. (scm_m_set_x): Memoize complete set! expression. Only leave symbols if no binding exists at memoization time. Throw error if assigning to a syntactic keyword. (lazy_memoize_variable): New function. (CEVAL): When execution set!, perform lazy memoization if unmemoized symbol is detected. * modules.c (module_variable): Return variables with unbound value. * tags.h: Fix comment. 2004-04-25 Kevin Ryde * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase, scm_c_downcase): Use ctype.h toupper and tolower. This will be useful in 8-bit locales, and ensures consistency with char-upper-case? and char-lower-case? which already use ctype.h. (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers): Remove. * chars.c, chars.h, init.c (scm_tables_prehistory): Remove. * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p call. Reported by Hyperdivision. * threads.c (scm_yield): Correction, actually call scm_thread_yield. Reported by Hyperdivision. * unif.c (s_scm_make_uve): Remove unused local variable. Reported by Hyperdivision. 2004-04-22 Dirk Herrmann Hide the implementation of ilocs and isyms in eval.c. * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST, SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST, SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST, SCM_ICDRP): Deprecated and added to deprecated.h. Moved from eval.h to eval.c. * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames, SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames, scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and renamed to ISYMNUM. * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1): Extracted printing of ilocs and isyms to guile internal functions scm_i_print_iloc, scm_i_print_isym of eval.c. 2004-04-22 Kevin Ryde * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift. * numbers.c (scm_round): Test for x already an integer, to avoid bad rounding in x+0.5 when x is a big value already an integer. In certain hardware rounding cases x+0.5 can give an adjacent integer, leading to that as the result, when we really just wanted x itself. 2004-04-19 Dirk Herrmann * eval.c (scm_unmemocopy): Fixed unmemoization of let*. (deval_args, CEVAL): Minor improvements: Reduced variable scopes, added const qualifiers, cast intentionally unused expressions to void for emphasis, improved comment. 2004-04-18 Dirk Herrmann * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag, scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed scm_tc9_flag to scm_tc8_flag. Introduced new identifier scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24. Defined the tc8-tag for flags to be 0x04, which will mean that SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due to the reduced number of bits and the simpler bit pattern for SCM_BOOL_F, certain machines may be able to use more efficient processor instructions to deal with SCM_BOOL_F. (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have never been defined in a released version, thus no need to deprecate them. (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8 instead of tc9 tags. (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead of tc9 tags. (SCM_MAKSPCSYM): Removed. It is almost impossible that user code could have used this definition. (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO, SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR, SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded as isyms, as special isyms don't exist any more. 2004-04-18 Kevin Ryde * filesys.c (scm_readdir): Use readdir_r when available, for thread safety. * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than explicit swapping code. 2004-04-15 Kevin Ryde * cpp_sig_symbols.in: Add SIGSYS. * list.c (scm_append_x): Use iterative style, to avoid non-tail recursion. * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac, frac/big and frac/frac, use scm_less_p for exact comparison. * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code with big/inum. * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf. 2004-04-06 Han-Wen Nienhuys * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag. * chars.h (scm_init_chars): change scm_{upcase,downcase} to scm_c_{up,down}case. (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc when hi-bit ASCII is subjected to SCM_MAKE_CHAR(). 2004-04-06 Kevin Ryde * numbers.c (scm_ash): Remove stray "}" in docstring. * numbers.c (scm_make_ratio): For inum/bignum integer detection, use x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid calling mpz_cmp_ui in most cases. * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui for big == abs(most-negative-fixnum) special case. (abs_most_negative_fixnum): Remove, no longer used. * scmsigs.c (scm_sigaction_for_thread): Correction to signum range test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on calling (sigaction NSIG). * simpos.c (scm_system_star): Fix execargv memory leak, merge parent and fork error cases to do this. 2004-04-03 Dirk Herrmann * eval.c (CEVAL): Don't distinguish between short and long instructions when dispatching - just always dispatch on the instruction code, which is common for short and long instructions. Further, removed unnecessary goto statements and added comment. 2004-04-03 Dirk Herrmann * eval.c (scm_unmemocopy): Don't distinguish between short and long instructions when dispatching - just always dispatch on the instruction code, which is common for short and long instructions. Further, removed unnecessary goto statements, fixed indentation and replaced SCM_IMP predicates by SCM_NULLP. 2004-04-03 Dirk Herrmann * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of comparison with SCM_ILOC00. In CEVAL, eliminate goto-label 'checkmacro'. 2004-03-31 Kevin Ryde * simpos.c: Include for SIG_IGN and friends. 2004-03-29 Dirk Herrmann Introduce scm_debug_mode_p as a replacement for scm_debug_mode and SCM_DEBUGGINGP: * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP), eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one single interface that also matches the naming conventions. Probably scm_debug_mode_p should be part of the private interface anyway. * debug.h (scm_debug_mode_p), backtrace.c (display_error_body), eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1, scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP to scm_debug_mode_p. Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr: * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr from debug.h to eval.h. * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any more, just leave it with setting scm_debug_mode_p, which is equivalent for practical purposes. * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x. * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval. * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval static and renamed it to ceval throughout. Provide a new exported but deprecated function scm_ceval as a wrapper for backwards compatibility. The same is done for the deval/scm_deval pair of functions. * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL throughout. Defined CEVAL to ceval or deval, based on compilation phase. * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p to ceval and deval instead of calling *scm_ceval_ptr. * eval.c (dispatching_eval): New deprecated static function. * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order to emulate its old behaviour as closely as possible. Change the evaluator such that only expressions for which pair? is true are passed to CEVAL, and such that all other expressions are evaluated outside of CEVAL: * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an expression that is assumed to be memoized already. All but expressions of the form '(
...)' are evaluated inline without calling an evaluator. * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but expressions of the form '( ...)' inline without calling an evaluator. * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle the special case of unmemoized symbols passed on the top level. * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it is known that the expression passed to CEVAL is of the form '( ...)'. Remove handling of the tc7-objects, since now it is known that the input expression of CEVAL is a pair. 2004-03-29 Dirk Herrmann * eval.c (is_self_quoting_p): New static function. (scm_m_quote): Use is_self_quoting_p. (copy_tree): Corrected typo in comment. 2004-03-28 Han-Wen Nienhuys * eval.c (s_scm_copy_tree): idem. * list.c (s_scm_filter): remove "pointer" from doc string. * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT. * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result. * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P (display_frame): idem. (display_backtrace_file_and_line): idem. * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK arguments. 2004-03-26 Kevin Ryde * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors. * numbers.c (scm_modulo): For inum/big and big/big, remove test of big==0 since that never occurs. * numbers.c, numbers.h (scm_modulo_expt): Renamed from scm_modular_expt, matching scheme level name `modulo-expt'. * numbers.c (scm_modular_expt): Return a negative remainder for a negative divisor, the same as `modulo' does. 2004-03-26 Eric Hanchrow * numbers.c, numbers.h (scm_modular_expt): New function. 2004-03-25 Kevin Ryde * numbers.c (scm_min, scm_max): Correction to big/real and real/big, return inexact as required by r5rs. 2004-03-24 Dirk Herrmann * eval.c: Separated some definitions relevant for execution from the memoization part of the file. (copy_tree): New static function (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic structures are detected now and will lead to an exception instead of forcing guile to run in an endless loop, using up all the system's memory. Second, arrays in the cdr of an improper list are now copied. See the new test cases in eval.test. 2004-03-24 Dirk Herrmann * posix.c (scm_gethostname): Make sure len is initialised before it is used. Restructured to (hopefully) represent possible configurations more clearly in the code. Added unwind handler. 2004-03-23 Kevin Ryde * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or MAXHOSTNAMELEN when available. 2004-03-21 Marius Vollmer * read.c (skip_scsh_block_comment): Also recognize '\r' as a line terminator. Rewritten the logic as a state machine, I must have been doing too much VHDL lately... * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to themselves. Thanks to Han-Wen Nienhuys! * list.c: Changed docstrings so that they no longer talk about returning 'pointers' to something. 2004-03-20 Han-Wen Nienhuys * gc.c: remove set_debug_cell_accesses! when SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on debugging conditionally. 2004-03-21 Kevin Ryde * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety. 2004-03-20 Kevin Ryde * posix.c (scm_gethostname): Preserve errno across free() call. 2004-03-18 Han-Wen Nienhuys * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting free cells. 2004-03-14 Kevin Ryde * stime.c: Define _GNU_SOURCE for strptime prototype from glibc. (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype. 2004-03-07 Kevin Ryde * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather than "GMT" always. (filltime): Make zname parameter "const". 2004-03-03 Mikael Djurfeldt * threads.c, threads.h (scm_c_scm2thread): New function. 2004-02-29 Kevin Ryde * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in particular don't assume "defined (__alpha__) && ! defined (linux)" means OSF. Remove "SCO" code, which was not really SCO specific and which John W. Eaton advises should be long past being needed. * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under error throw. 2004-02-24 Kevin Ryde * posix.c (scm_cuserid): Use a private result buffer, for thread safe. 2004-02-22 Kevin Ryde * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for complex, same as for two args. (Handle only inum, big, real, frac). 2004-02-21 Kevin Ryde * posix.c (scm_crypt): Use new HAVE_CRYPT. (): Remove HAVE_LIBCRYPT condition. Reported by Andreas Voegele. 2004-02-20 Neil Jerram * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around validation. * read.c (scm_lreadparen): Removed. (scm_lreadparen1): Renamed scm_i_lreadparen. 2004-02-20 Han-Wen Nienhuys * list.c (scm_list_n): validate non-immediate arguments; this will catch forgotten a SCM_UNDEFINED. 2004-02-18 Marius Vollmer * gc.h (scm_gc_cells_collected): Removed duplicated declaration. Thanks to Bill Schottstaedt! * socket.h (scm_gethost): Removed prototype it is already in "net_db.h". Thanks to Bill Schottstaedt! 2004-02-18 Kevin Ryde * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word order parameter to mpz_import, in fact with just one word there's no order to worry about at all. * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real and frac==complex, make an exact comparison rather than converting with fraction2double. * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin shared library, since environ is not directly available there. * script.c (scm_shell_usage): Print to stdout for --help, per GNU standard. * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default errno EINVAL in case localtime and gmtime don't set it. (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our SCM_SYSERROR, since mktime and strptime generally don't set errno. 2004-02-16 Kevin Ryde * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes, which were permitted in the past for these. * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per previous change to numbers.c. * script.c (scm_shell_usage): Print bug-guile email address, as per GNU standard. Reported by Han-Wen Nienhuys. 2004-02-13 Mikael Djurfeldt * unif.c (scm_make_uve): Removed local variable and simplified code in order to avoid compiler used uninitialized warnings. * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from scm_hash_map. (scm_hash_fold): Use scm_call_3 directly in the call to scm_internal_hash_fold instead of going via fold_proc (which is now removed). (scm_hash_for_each): Use a trampoline + scm_internal_hash_for_each_handle. (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New functions. 2004-02-12 Kevin Ryde * ports.c (scm_port_line): In docstring, note first line is 0. (scm_set_port_line_x): In docstring, note first line is 0. (scm_port_column): In docstring, there's no default to current input port, and remove shared port-line @defun. (scm_set_port_column_x): In docstring, there's no default to current input port, note first column is 0, remove shared set-port-line! @defun. * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to convert args the same way that array-set! does. * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype for dvect. (scm_array_p): Add missing "break"s in switch, fix llvect test look for "l" not "s", fix dvect to be false for singp(prot) since such a value is for fvect. (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33. (exactly_one_third): New variable. (scm_init_unif): Initialize it. 2004-02-10 Neil Jerram * read.c (scm_read_opts): Change `escaped-parens' to `elisp-strings'. 2004-02-08 Neil Jerram * read.c (scm_read_opts): New opts `elisp-vectors' and `escaped-parens'. (s_vector): New. (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.

(SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New. 2004-01-23 Han-Wen Nienhuys * eval.c (m_expand_body): remove stray variable new_body. 2004-01-22 Marius Vollmer * eval.c (m_expand_body): Rewrite the expression in place (by overwriting FORMS) also when a letrec is constructed, not only when no definitions are found. Do not return rewritten expression to emphasize the in-place rewriting. Changed all users. 2004-01-19 Han-Wen Nienhuys * gc.c: add protected_object_count, a number that is dumped from gc_stats() 2004-01-11 Marius Vollmer * dynwind.h, dynwind.c (scm_frame_unwind, scm_frame_unwind_handler): Renamed and changed all uses. (scm_frame_rewind, scm_frame_rewind_handler): Likewise. 2004-01-11 Kevin Ryde * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x, s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per changes made to scheme-compound.texi. 2004-01-10 Marius Vollmer * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#, #{.}#, and all numeric strings specially. Thanks to Paul Jarc! * guile-snarf.in: Use mkdir to create a unique temporary directory that we can safely use. Thanks to Stefan Nordhausen! 2004-01-07 Marius Vollmer * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit' argument since it is always zero now. Changed all callers. Removed code for handling fluids. * fluids.c (scm_c_with_fluids): Use frames instead of adding to the wind chain explicitely. Use scm_c_with_fluid for the common case of only one fluid. (scm_with_fluid): New. (scm_c_with_fluid): Use frames instead of scm_c_with_fluids. * fluids.h, fluids.c (scm_frame_fluid): New. (scm_with_fluid): New. (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed. * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead, do the unwinding directly.

Reported by Richard Todd. * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while traversing the args list, fixes segv if an improper list is given. Reported by Rouben Rostamian. 2004-01-06 Marius Vollmer * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate swap_data on stack, use a 'malloc obj'. * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids, scm_swap_fluids, scm_swap_fluids_reverse): Renamed to scm_i_... since they are internal. Changed all uses. * dynwind.c (frame_print): Removed, use the default printer. (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New. (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above to protect SCM values. * dynwind.h (SCM_F_WIND_EXPLICITELY, SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn. Changed all uses.

(scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to scm_i_dowinds and extended to handle frames and to invoke a 'turn' function when the outermost wind point has been reached. The latter is used to copy a continuation stack at the right time. scm_dowinds remains available. (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA, tc16_guard, guards_print): Removed. (scm_internal_dynamic_wind): Reimplemented using frames. * continuations.c (copy_stack): New, do only the stack copying part of copy_stack_and_call.

(scm_dynthrow): Do not call scm_dowinds, this is now done by copy_stack_and_call. 2004-01-04 Kevin Ryde * numbers.c (scm_less_p): Don't convert frac to float for compares, can give bad results due to rounding. * stime.c (scm_current_time, scm_gettimeofday): Add a comment about setzone/restorezone protection for DOS. 2003-12-26 Marius Vollmer * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax and scm_t_uintmax to be defined in scmconfig.h 2003-12-03 Kevin Ryde * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case. * numbers.c (scm_make_ratio): Check for numerator equal to SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that, giving integer -1. * numbers.c (scm_real_part): Return fraction unchanged rather than converting to flonum. 2003-11-30 Dirk Herrmann * modules.c (module_variable): Fixed (and thus simplified) the definition of SCM_BOUND_THING_P to reflect the fact that since after the 1.4 series of guile, obarrays only hold variable objects. 2003-11-30 Marius Vollmer * numbers.c (scm_logand): It's "#b...", not "#\b...". From Paul Jarc: * read.c (scm_lreadr): Signal an error for invalid escape sequences in strings.

(m_body): Fixed comment. (scm_m_define): Don't generate memoized code for definitions that are not on the top level. As a consequence, no memoized code at all is generated for definitions any more: Top level definitions are executed immediately during memoization and internal definitions are handled separately in m_expand_body. (scm_unmemocopy, unmemocopy): Removed code for unmemoizing definitions. Consequently, there is no unmemoizing code any more that might modify the environment. Thus, the old scm_unmemocopy is removed and the old unmemocopy is renamed to scm_unmemocopy. (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP over SCM_NIMP in places, where the argument is known to be part of a proper list. 2003-11-21 Kevin Ryde * numbers.c (scm_abs): Allocate a new real only for negatives, as done for bignums. * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case to share some shifting. * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM, since gc does this. 2003-11-19 Marius Vollmer * numbers.c (scm_make_ratio): Rewritten to have a simpler structure. Previously, not all cases with a negative denominator were covered. * numbers.c (mem2decimal_from_point): use scm_divide instead of scm_divide2real when forming the fractional part. This allows "#e1.2" to yield 6/5. * numbers.c (scm_i_fraction_equalp): Do not treat the return value of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all fractions were equal to each other regardless of value. Ooops. * numbers.c (scm_rationalize): Return an inexact result when given inexact arguments. * numbers.c (scm_exact_p, scm_inexact_p): Throw error for non-numbers. 2003-11-18 Marius Vollmer Support for exact fractions from Bill Schottstaedt!

This allows (@ ...) to work with set!. (scm_m_generalized_set_x): Use ASSERT_SYNTAX_2 instead of SCM_ASSYNT. * script.c (scm_compile_shell_switches): Use scm_c_read_string for the "-e" option instead of scm_str2symbol. This allows things like (@ ...) to be specified for the entry point. 2003-11-16 Dirk Herrmann * eval.c (scm_m_letstar): Create memoized code in place to minimize consing. 2003-11-16 Dirk Herrmann * eval.c (s_splicing): Commented and reformulated. (lookup_global_symbol, lookup_symbol): New static functions. (s_test, s_bindings, s_duplicate_bindings, s_variable): Removed.

The goal is to remove definitions of evaluator memoization codes completely from the public interface. This will make it possible to experiment more freely with optimizations of guile's internal representation of memoized code. * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM. * print.c (iflagnames): New array, holding the printed names of guile's special constants ('flags').

Thanks to Paul Jarc! 2003-09-14 Dirk Herrmann * tags.h: Reduced the number of short instructions from 14 to 13. The typecode of the former 14th short instruction is now used to represent long instructions. Changed some comments to reflect this fact. (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was previously used by SCM_IM_DEFINE. (SCM_IM_DEFINE): Turned into a long instruction. * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long instruction. * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7 code that is separate from all instructions, one level of dispatch for long instructions can be eliminated. * print.c (scm_isymnames): Removed some commented code. 2003-09-12 Marius Vollmer * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel compiler on IA64. * hashtab.h (scm_tc16_hashtable): Added "extern" declaration. * modules.c (scm_module_reverse_lookup): Check that the obarray really is a hashtable and do nothing if not. * inline.h: Use "extern inline" only with GCC. Use "static inline" else. 2003-09-06 Dirk Herrmann * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP. * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP, SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to deprecated.h. 2003-09-06 Dirk Herrmann * eq.c (scm_eqv_p, scm_equal_p): Removed uses of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP. * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from 0.0==some_expression to some_expression==0.0. The latter is better readable. The former is preferred by some people, since it leads to a compiler error when confusing == with =. However, when using gcc, a warning will be issued if in an if-statement an assigment appears. Since many Guile developers are using gcc, such errors will not remain unnoticed anyway. We can therefore focus on better readability. 2003-09-04 Dirk Herrmann * tags.h: Added description of Guile's type system. Removed some old and misleading comments. 2003-09-04 Dirk Herrmann * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP. 2003-09-04 Dirk Herrmann * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int. (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the respective SLOPPY macro. 2003-09-04 Dirk Herrmann * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of type string, not SCM_TYP7S. 2003-09-03 Kevin Ryde * numbers.c (scm_lognot): Correction to docstring, ones-complement not 2s-complement. * stime.c (scm_strptime): Add comment about glibc strptime %s and current timezone requiring SCM_DEFER_INTS. 2003-08-30 Neil Jerram * script.c (scm_compile_shell_switches): Make -s switch optional if file to be loaded does not begin with a `-'. (Thanks to Aaron VanDevender for the patch!) 2003-08-30 Kevin Ryde * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness and to have non-integer types rejected as per other logical funcs. 2003-08-28 Kevin Ryde * gc.h (scm_remember_upto_here_1): Revise comments on the asm form. 2003-08-23 Kevin Ryde * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be thread safe, and could take a long time too. 2003-08-22 Kevin Ryde * numbers.c (scm_difference): Correction to bignum - negative inum. 2003-08-14 Kevin Ryde * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2) [__GNUC__]: Use volatile asm macros rather than a function call. * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine macros while defining functions. * simpos.c (getenv): Use for prototype. (scm_system): In docstring, refer to status:exit-val rather than "functions above". 2003-08-09 Kevin Ryde * srcprop.c (scm_source_properties): Return plist from hash if it's a list set by source-properties! rather than an SRCPROPS object, 2003-07-29 Kevin Ryde * properties.c (scm_primitive_property_ref): In docstring, note parameters to not-found-proc, use hyphens rather than underscores for that parameter name. (scm_primitive_property_set_x): In docstring, VAL is the value parameter not CODE. 2003-07-27 Marius Vollmer * print.c (scm_print_symbol_name): handle more weird characters by escaping the symbol name properly. Thanks to Paul Jarc! * posix.h (scm_setgroups): New prototype. * posix.c (scm_setgroups): New. Thanks to Paul Jarc! (scm_getgroups): Handle groups ids that don't fit into a fixnum. Don't use SCM_WRITABLE_VELTS. * gc.h (SCM_GC_SET_CELL_BVEC): New. * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to Matthias Koeppe! * __scm.h (SCM_C_INLINE_KEYWORD): New. * numbers.c: Use it in place of SCM_C_INLINE so that the code compiles when SCM_C_INLINE is undefined. 2003-07-24 Dirk Herrmann * __scm.h: Reformulated the architecture and compiler properties in terms of properties of scm_t_bits and SCM variables rather than in terms of c standard types. This is since it is not known which of the standard types scm_t_bits and SCM variables will be defined to. 2003-07-24 Kevin Ryde * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum and real. 2003-07-18 Kevin Ryde * numbers.c (scm_product): In complex * bignum, correction to REAL/IMAG fetch, x is the complex, not y. 2003-07-13 Mikael Djurfeldt * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of scm_inf_p test as Scheme values. (scm_sum): Bugfix: Normalize bignum created from a negative bignum and a positive inum. Use GNU indentation style. 2003-07-12 Dirk Herrmann * values.c (scm_values): Build lists of length 1 by using scm_list_1 instead of using scm_cons. 2003-07-10 Kevin Ryde * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end. * list.c (scm_list_n): Ditto. * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function. 2003-07-08 Matthias Koeppe * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for scm_t_bits and scm_t_signed_bits to avoid any chance of one and not the other using intptr_t. 2003-07-08 Kevin Ryde * numbers.c (scm_make_polar): Use sincos, when available. (scm_magnitude): Use hypot. * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use @footnote since it doesn't go through to guile-procedures.txt. * threads.c (scm_call_with_new_thread): In docstring, use "( )" outside @var to quieten makeinfo, and use @code. 2003-07-06 Han-Wen Nienhuys * gc-malloc.c (decrease_mtrigger): new function (increase_mtrigger): new function, separate debug registering and mtrigger administration. (scm_gc_realloc): bugfix: do mtrigger administration before the actual realloc, for the realloc might invalidate a GC-d segment of memory. Thanks to Sam Hocevar for pointing this out. (scm_gc_realloc): use scm_malloc_reregister instead of unregistering and registering in sequence. 2003-07-03 Han-Wen Nienhuys * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)" 2003-07-02 Han-Wen Nienhuys * __scm.h (SCM_ASRTGO): add "else" to macro expansions with if clauses. 2003-06-29 Marius Vollmer * deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops, scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array, scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA, RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY, SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from the release_1_6 branch. 2003-06-25 Stefan Jahn * continuations.c: Redeclaration of getcontext() via the __asm__ ("getcontext") directive. * continuations.h: Include instead of . 2003-06-21 Kevin Ryde * numbers.c (_GNU_SOURCE): #define, to get C99 things. (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh, $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when available. (scm_inexact_to_exact): Expand isfinite to its definition !xisinf. (isfinite): Remove, conflicts with C99 isfinite(). 2003-06-19 Marius Vollmer * deprecated.h, deprecated.c (scm_strhash, scm_sym2ovcell_soft, scm_sym2ovcell, scm_intern_obarray_soft, scm_intern_obarray, scm_symbol_value0, scm_string_to_obarray_symbol scm_intern_symbol, scm_unintern_symbol, scm_symbol_binding, scm_symbol_interned_p, scm_symbol_bound_p, scm_symbol_set_x, scm_gentemp): Re-added from the release_1_6 branch. 2003-06-14 Stefan Jahn * threads.h: Redefined scm_getspecific() and scm_setspecific() to be functions instead of macros. * threads.c: Conditionalized inclusion of and . (scm_getspecific, scm_setspecific): Made these two function real part of the API. * posix.c (s_scm_putenv): Added some code to make a (putenv "FOO="), i.e. setting an empty string, work also on Win32 systems. Thanks to Kevin Ryde for the proposal. 2003-06-12 Kevin Ryde * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add freebsd to comment about need to use unsetenv. 2003-06-02 Marius Vollmer * ports.c (scm_peek_char): Safe the column of the port around the getc/ungetc calls. Thanks to Dr. Peter Ivanyi! 2003-06-07 Kevin Ryde * tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX and friends required by scm_t_bits setups. 2003-06-06 Dirk Herrmann * tags.h (scm_tc2_int): Added. * tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of scm_tc2_int. * tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct, scm_tcs_closures): Hard coded values replaced by symbolic ones. 2003-06-05 Dirk Herrmann * eval.c: Partially undid my patch from 2003-05-31. This patch caused the segfault referenced in the previous changelog entry. 2003-06-05 Dirk Herrmann * tags.h: Fixed comment about the immediate type code layout. * eval.c: Fixed handling of non-special instructions. Without this patch, guile will segfault on (#\0) and similar instructions. 2003-06-05 Kevin Ryde * numbers.c (scm_max, scm_min): For inum, bignum and real, if other operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d. * read.c (scm_input_error): Pass arg list parameter to scm_error_scm, rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr. 2003-06-04 Dirk Herrmann * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT, SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and generalized it to apply not only to C level functions but also to scheme level functions. * debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?, scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?, scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p, respectively. * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC, SCM_IDSTMSK): Deprecated. The macro definitions are moved from eval.h into eval.c and a copy is placed into deprecated.h. * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed into eval.c. This definition was not part of the API in any officially released version of guile and thus does not need to go through a phase of deprecation. 2003-06-02 Dirk Herrmann * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression, scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals): Deprecated. In eval.c the definitions are make static and renamed from scm_s_xxx to s_xxx. In deprecated.c the original definitions are copied. * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL, SCM_XEVALCAR): Deprecated. The macro definitions are moved from eval.h into eval.c and a copy (slightly modified to work in user code) is placed into deprecated.h. * eval.c: Use the local static s_xxx definitions instead of the scm_s_xxx definitions throughout. 2003-06-01 Dirk Herrmann This set of patches separates the representation of the cxr family of functions (car, cdr etc.) from the dsubr family of functions (i. e. functions that take a double precision floating point argument). Further, the algorithm for handling the cxr function is improved. * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_1), numbers.c (scm_asinh, scm_acosh, scm_atanh, scm_truncate, scm_round, floor, ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh, cosh, tanh), objects.c (scm_class_of), procprop.c (scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h (scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new typecode for the dsubr family of functions. * ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to ramap_dsubr. * eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c (scm_init_pairs): Make use of the (now usable) second cell element of a scm_tc7_cxr function to implement the cxr family of functions more efficiently. 2003-05-31 Dirk Herrmann * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0, scm_trampoline_1, scm_trampoline_2): Postpone error cases to the end of an if-else-if-sequence of checks. 2003-05-30 Dirk Herrmann * eval.c (SCM_CEVAL): Improved readability of call-with-values execution. Generalize apply_closure to apply_proc and use that for call-with-values. 2003-05-30 Dirk Herrmann * eval.c (SCM_CEVAL): Avoid one level of indirection when applying a non closure. 2003-05-30 Stefan Jahn * posix.c (s_scm_putenv): Use the new HAVE_UNSETENV appropriately for mingw32 hosts. * numbers.h: Defining copysign(), isnan() and finite() to be prefixed by a single '_' for mingw32 hosts. 2003-05-30 Kevin Ryde * numbers.c (z_negative_one): New variable. (scm_init_numbers): Initialize it. (scm_logcount): Use it and mpz_hamdist to count zeros for negatives. 2003-05-29 Stefan Jahn * win32-dirent.c: Use malloc() instead of scm_malloc(). * stime.c (s_scm_strftime): Add a type cast to avoid compiler warning. * posix.c (s_scm_putenv): Disable use of unsetenv() for the mingw32 build. * modules.c (s_scm_module_import_interface): Renamed local variable interface to _interface. Seems like 'interface' is a special compiler directive for the mingw32 compiler. * mkstemp.c: Provide prototype to avoid compiler warning. * load.c (s_scm_search_path): Fixed absolute and relative path detections for native Windows platforms. * gc.h, threads.h: Export some more symbols using SCM_API (necessary to build on mingw32). * gc-freelist.c ("s_scm_map_free_list", "s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME. * fports.c (fport_fill_input): Disable use of fport_wait_for_input() on Win32 platforms. * filesys.c (s_scm_basename): Fixed __MINGW32__ code. * Makefile.am: Modified some rules for cross compiling. 2003-05-25 Dirk Herrmann * eval.c (SCM_CEVAL): In case of an application, all checks for a proper function object and the correct number of arguments are now performed in the application part of SCM_CEVAL. (scm_badformalsp): Removed. 2003-05-25 Dirk Herrmann * deprecated.c (scm_read_and_eval_x): Fixed C99-ism. 2003-05-22 Mikael Djurfeldt * num2integral.i.c (NUM2INTEGRAL): Avoid warning about conditional always being false by inserting preprocessor conditional. (Thanks to Bruce Korb.) * __scm.h (SCM_STACK_PTR): New macro. (Cast argument through (void *) in order to avoid an aliasing warning; thanks to Bruce Korb.) * stackchk.h (SCM_STACK_OVERFLOW_P): Use SCM_STACK_PTR. * threads.c (suspend, launch_thread, scm_threads_mark_stacks): Use SCM_STACK_PTR. * threads.c (scm_threads_mark_stacks): Bugfix: Changed thread->base --> t->base. * eval.c (SCM_CEVAL): Don't cast argument of SCM_STACK_OVERFLOW_P. 2003-05-20 Marius Vollmer * deprecated.h, deprecated.c (scm_makstr, scm_makfromstr, scm_variable_set_name_hint, scm_builtin_variable, scm_internal_with_fluids, scm_make_gsubr, scm_make_gsubr_with_generic, scm_create_hook, SCM_LIST0, SCM_LIST1, SCM_LIST2, SCM_LIST3, SCM_LIST4, SCM_LIST5, SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify, scm_sloppy_memq, scm_sloppy_memv, scm_sloppy_member, scm_read_and_eval_x, scm_subr_entry, SCM_SUBR_DOC, scm_make_subr, scm_make_subr_with_generic, scm_make_subr_opt, scm_call_catching_errors, scm_make_smob_type_mfpe, scm_set_smob_mfpe, scm_strprint_obj, scm_read_0str, scm_eval_0str, SCM_CHARS, SCM_UCHARS, SCM_LENGTH): Re-added from the release_1_6 branch. Some have been slightly rewritten. (scm_i_object_chars, scm_i_object_length): New, to support SCM_CHARS, SCM_UCHARS, and SCM_LENTH. 2003-05-19 Dirk Herrmann * eval.c (scm_m_do, unmemocopy, SCM_CEVAL): Reversed order of names and inits in the memoized code of do. 2003-05-19 Mikael Djurfeldt * c-tokenize.lex (yyget_lineno, yyget_in, yyget_out, yyget_leng, yyget_text, yyset_lineno, yyset_in, yyset_out, yyget_debug, yyset_debug, yylex_destroy): Added prototypes (otherwise we'll get a compilation error if error-on-warning is enabled). 2003-05-17 Marius Vollmer * c-tokenize.lex: Gobble up complete lines after a '#'. This removes preprocessor directives from the snarfage that might otherwise confuse us. These directives appear when compiling with "-g3", for example. 2003-05-16 Han-Wen Nienhuys * ChangeLog: add my surname * srcprop.c (scm_finish_srcprop): use scm_gc_register_collectable_memory() (scm_make_srcprops): idem. 2003-05-14 Han-Wen Nienhuys * gc-malloc.c (scm_gc_register_collectable_memory): avoid wrap-around for scm_mtrigger (scm_gc_register_collectable_memory): abort on overflowing scm_mallocated(). 2003-05-13 Kevin Ryde * numbers.c (xmpz_cmp_d): New macro, handling infs if gmp doesn't. (scm_num_eq_p, scm_less_p, scm_max, scm_min): Use it. 2003-05-12 Mikael Djurfeldt * backtrace.c (scm_display_error_message): Introduced fancy printing with max level 7 and length 10. (Purpose: avoid printing gigantic objects in error messages.) * print.c, print.h (scm_i_port_with_print_state): New function. * print.c (scm_iprin1, scm_printer_apply, scm_port_with_print_state): Use scm_i_port_with_print_state. (scm_simple_format): Modified not to destroy print states. (print_state_mutex): New mutex. (scm_make_print_state, scm_free_print_state, scm_prin1): Lock/unlock print_state_mutex. * deprecated.h (SCM_GC8MARKP, SCM_SETGC8MARK, SCM_CLRGC8MARK): Use current names in definitions. 2003-05-10 Kevin Ryde * numbers.c (scm_num_eq_p, scm_less_p): Don't pass NaN to mpz_cmp_d. * numbers.c (scm_integer_length): On negative bignums, adjust mpz_sizeinbase to account for it looking at absolute value where we want ones-complement. * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui since we're only using the ulong return value, and x might not fit. 2003-05-06 Dirk Herrmann * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to read. This will allow to make the definition in read.c static. 2003-05-06 Dirk Herrmann * eval.c, eval.h, evalext.c, evalext.h (scm_m_undefine): Moved from evalext to eval. This will allow to make some of the definitions in eval.c static. 2003-05-06 Kevin Ryde * numbers.c (scm_difference): In inum - bignum, handle negative inum. (scm_logcount): Use mpz_com, not mpz_neg. 2003-05-04 Dirk Herrmann The purpose of this patch is to make guile's internal memoizers distinguishable from memoizing macros created on the scheme level or from user provided primitive memoizing macros. The reason is, that the internal memoizers are the only ones that are allowed to transform their scheme input into memoizer byte code, while all other memoizing macros may only transform scheme code into new scheme code. To achieve this, a new macro type 'builtin-macro!' is introduced. Currently, 'builtin-macro!'s are handled as memoizing macros, but this will change when the memoizer and executor are separated. * macros.[ch] (scm_i_makbimacro): New. * macros.h (SCM_BUILTIN_MACRO_P): New. * macros.c (macro_print, scm_macro_type): Support builtin-macro!s. * eval.c, goops.c: All of guile's primitive memoizing macros are primitive builtin-macros now. * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive builtin-macros are handled equally to memoizing macros. 2003-05-04 Marius Vollmer * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to work around a bug in GCC 2.95.2 but is now a bug in itself. 2003-05-02 Marius Vollmer * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols): New. 2003-04-30 Marius Vollmer * deprecated.h, deprecated.c (scm_protect_object, scm_unprotect_object, SCM_SETAND_CAR, SCM_SETOR_CAR, SCM_SET_AND_CDR, SCM_SET_OR_CDR, SCM_FREEP, SCM_NFREEP, SCM_GC8MARKP, SCM_SETGC8MARK, SCM_CLRGC8MARK, SCM_GCTYP16, SCM_GCCDR, scm_remember, scm_the_root_module, scm_make_module, scm_ensure_user_module, scm_load_scheme_module, scm_port, scm_ptob_descriptor, scm_port_rw_active, scm_close_all_ports_except): New. * ports.c (scm_c_port_for_each): New function, mostly copied from scm_port_for_each. (scm_port_for_each): Reimplemented using scm_c_port_for_each. * ports.h (scm_c_port_for_each): New prototype. 2003-04-28 Mikael Djurfeldt * eval.c (scm_m_atdispatch): Removed until actually needed. (This macro was introduced in anticipation of GOOPS method compilation code.) * goops.c: Removed binding of @dispatch. 2003-04-28 Dirk Herrmann * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the instructions that bind the macros on the scheme level back to goops.c in order to make sure again that the bindings go into the (oop goops) module and are not visible from the outside. 2003-04-27 Dirk Herrmann * eval.c: Non functional change: Separated R5RS and non-R5RS macros into different sections of the file and ordered the memoizers alphabetically. 2003-04-27 Dirk Herrmann * eval.c (scm_ilookup): Rewritten to improve readability. 2003-04-27 Dirk Herrmann * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2): Partially reverted patch from 2003-04-23 in oder to find a better compromise between readability and debuggability. 2003-04-25 Dirk Herrmann * eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref, scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and definitions of the special goops memoizers from goops.[ch] to eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used throughout guile. 2003-04-24 Mikael Djurfeldt * ports.c, ports.h (scm_i_port_table_mutex): New mutex. * fports.c (scm_evict_ports): Lock/unlock scm_i_port_table_mutex. * ports.c (scm_close_port, scm_flush_all_ports): Ditto. * ioext.c (scm_fdes_to_ports): Ditto. * vports.c (scm_make_soft_port): Changed SCM_DEFER/ALLOW_INTS into lock/unlock scm_i_port_table_mutex. * strports.c (scm_mkstrport): Ditto. * ports.c (scm_void_port, scm_port_for_each): Ditto. * fports.c (scm_fdes_to_port): Ditto. 2003-04-23 Dirk Herrmann This set of patches contains no functional changes, only debatable minor stylistic ones. Still, in order to prepare a patch between my local copy and the CVS version, I decided to submit the changes below. Then, the patch will hopefully only contain relevant modifications :-) * eval.c (iqq): Added const specifier. * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2): Use NULL instead of 0 to indicate that a pointer is returned. Removed some misleading 'fall through' comments. * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2): Split up long expressions into smaller ones to be more debugging friendly. 2003-04-23 Dirk Herrmann * eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value rather than casting to SCM. 2003-04-23 Dirk Herrmann * sort.c, pairs.h: Removed unnecessary includes. 2003-04-23 Dirk Herrmann * sort.c: Replaced hand-made trampline code by the new official mechanism from eval.c.

(scm_i_inherit_applicable): New function. * goops.c, goops.h (scm_class_applicable, scm_class_extended_accessor): New classes. 2003-03-18 Dirk Herrmann * procs.c (scm_procedure_documentation): Removed redundant SCM_NIMP test and replaced other calls to SCM_IMP by more explicit predicates. 2003-03-11 Mikael Djurfeldt * list.c, list.h (scm_filter, scm_filter_x): New functions. * modules.c (scm_module_import_interface): New function. * goops.c, goops.h (scm_class_accessor_method): Renamed from scm_class_accessor. (scm_class_accessor): New class. 2003-03-06 Mikael Djurfeldt * goops.c (scm_primitive_generic_generic): Enable primitive generic if not enabled. (scm_sys_goops_loaded): Setup unextended primitive generics. * goops.c, goops.h (scm_c_extend_primitive_generic): New function. * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New snarf macros. * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a testing example. All uses of SCM_GPROC should be converted.) * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of scm_assoc. * eq.c (scm_equal_p): Turned into a primitive generic. 2003-02-27 Rob Browning * Makefile.am (scmconfig.h): new target -- generate file from ../config.h. (modinclude_HEADERS): remove version.h. (nodist_modinclude_HEADERS): add version.h. 2003-02-24 Mikael Djurfeldt This fixes a serious GC bug, introduced during the latest reorganization of the GC, which disabled freeing of structs and GOOPS objects: * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to SCM_EOL. (scm_struct_prehistory): Move scm_free_structs to scm_before_mark_c_hook. * gc-card.c (sweep_card): Check that we haven't swept structs on this card before. That can happen if scm_i_sweep_all_segments has been called from some other place than scm_igc. 2003-02-19 Mikael Djurfeldt * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31 (since hash tables now adapt their size). * modules.c (scm_modules_prehistory): Changed from 2001 to 1533 (current number of prehistory bindings; hashtable code will select a prime which is greater than this value). * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139 (current number of initial symbols). * properties.c (scm_init_properties): Don't specify size of scm_properties_whash. * objprop.c (scm_init_objprop): Don't specify size of scm_object_whash. * keywords.c (scm_init_keywords): Don't specify a hash table size. * hooks.c (scm_c_hook_add): Fixed bug in append mode. The following changes introduce the use of resizable hash tables throughout Guile. It also renames the old *-hash-table* functions to *-alist-vector* and places them, together with the rest of the weak vector support, in the module (ice-9 weak-vector). We should probably introduce a new, better, API for weak references, for example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even look like and are used like ordinary pairs.) * environments.c (obarray_enter, obarray_retrieve, obarray_remove, leaf_environment_fold, obarray_remove_all): Use hashtable accessors. * gc.c (scm_init_storage): Moved hook initialization to scm_storage_prehistory. (scm_storage_prehistory): New function. (scm_igc): Added commentary about placement of scm_after_sweep_c_hook. * gc-mark.c (scm_mark_all): Use hashtable accessors. (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and SCM_WVECT_WEAK_VALUE_P. * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New functions. (scm_vector_to_hash_table, scm_c_make_resizing_hash_table): Removed. (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table): Moved here from weaks.c. * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added calls to scm_storage_prehistory and scm_hashtab_prehistory. * modules.c (module-reverse-lookup): Use hashtable accessors. * symbols.c, symbols.h (scm_i_hash_symbol): New function. * weaks.c, weaks.h (scm_make_weak_key_alist_vector, scm_make_weak_value_alist_vector, scm_make_doubly_weak_alist_vector): New functions. * weaks.c (scm_init_weaks_builtins): New function. * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE, SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P, SCM_WVECT_NOSCAN_P): New macros. * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P and SCM_WVECT_WEAK_VALUE_P. * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from allocate_weak_vector and exported. 2003-02-13 Mikael Djurfeldt * hashtab.c: Undid thread safety. (We decided that it's better to let the user explicitly protect the tables (or not) according what is suitable for the application.) 2003-02-12 Mikael Djurfeldt * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made thread safe and handle resizing tables. (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed SCM_DEFER/ALLOW_INTS. 2003-02-11 Mikael Djurfeldt * hashtab.c (scm_vector_to_hash_table, scm_c_make_resizing_hash_table, scm_make_hash_table): New functions. (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread safe and handle resizing tables. * weaks.c (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table): Size argument made optional. Return resizable table if not specified. 2003-02-10 Mikael Djurfeldt * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2): Fixed formals tests for closures. (Thanks to Kevin Ryde.) 2003-02-05 Mikael Djurfeldt * debug.c (scm_procedure_source): Handle all objects for which procedure? is #t. (Thanks to Bill Schottstaedt.) 2003-01-23 Mikael Djurfeldt * futures.c (mark_futures): Don't need to mark data of recycled futures. (scan_futures, cleanup_undead): Be smarter about marking futures---avoid unnecessary passes through future lists. * futures.h, futures.c: New files; Introduced recycling of futures. For fine-grained threading this lifts performance to another level. We can now use parallelization in inner loops of Guile programs without impossible overhead. * threads.h, threads.c: Moved futures to their own file. * Makefile.am (libguile_la_SOURCES): Added futures.c. (DOT_X_FILES): Added futures.x. (DOT_DOC_FILES): Added futures.doc. (modinclude_HEADERS): Added futures.h. * threads.c, threads.h (scm_i_create_thread): Renamed from create_thread and made global. * futures.c (scm_make_future): New procedure. * eval.c: #include "libguile/futures.h". * init.c: #include "futures.h" (scm_init_guile_1): Call scm_init_futures. * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK. * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here. * eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New functions. * eval.c (scm_trampoline_1): Fixed arguments test for closures. 2003-01-22 Mikael Djurfeldt * threads.c (create_thread): Don't unwind dynwind chain of parent thread before creation. Just start the new thread with an empty dynwind chain. 2003-01-20 Mikael Djurfeldt * evalext.c, evalext.h (scm_self_evaluating_p): New function. 2003-01-10 Mikael Djurfeldt * threads.c (scm_timed_wait_condition_variable): Support timed waiting also for simple condition variables. * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead of calling the procedure change-object-class. 2003-01-09 Mikael Djurfeldt * ramap.c (scm_ramapc): Typo in error message. 2003-01-08 Mikael Djurfeldt * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for slots with instance allocation. * goops.c, goops.h (scm_class_extended_generic_with_setter): New class. (scm_compute_applicable_methods): Use scm_generic_function_methods. * goops.c (scm_generic_function_methods): Support extended generic functions. 2002-12-29 Mikael Djurfeldt * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future. Thanks to Neil for pointing this out! 2002-12-29 Neil Jerram * lang.h: Remove declarations matching definitions removed from lang.c (just below). 2002-12-28 Neil Jerram * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null, scm_m_while, scm_nil_eq): Remove definitions that were superfluous and already commented out. * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token, scm_lreadparen): Support reading vectors with Elisp syntax if SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS is not currently defined, and there isn't even a configure switch to enable it yet.) 2002-12-26 Marius Vollmer * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath builds work. (EXTRA_DIST): Added version.h.in. 2002-12-21 Mikael Djurfeldt This change makes it possible for one thread to do lazy sweeping while other threads are running. Now only the mark phase need to have all threads asleep. We should look further into this issue. Presently, I've put the locking of scm_i_sweep_mutex at "conservative" places due to my current lack of knowledge about the garbage collector. Please feel free to restrict these regions further to allow for maximal parallelism! * gc.c, gc.h (scm_i_sweep_mutex): New mutex. * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory): Substitute locking of scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep. (scm_igc): Lock sweep mutex here instead of in callers; Calls to scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate the single-thread section (which now only contains the mark phase). (scm_gc): Don't lock sweeo mutex here since scm_igc locks it; Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly. * threads.c (gc_section_mutex): Removed. 2002-12-19 Mikael Djurfeldt * threads.c (create_thread): Clear parent field in root state in order not to unnecessarily remember dead threads. * eval.c (call_subr2o_1, call_lsubr2_2): New functions. (scm_trampoline_1, scm_trampoline_2): Use them. 2002-12-18 Mikael Djurfeldt Partial introduction of real plugin interface. * Makefile.am (modinclude_HEADERS): Added threads-plugin.h. (EXTRA_DIST): Added threads-plugin.c. * threads-plugin.h, threads-plugin.c: New files. * threads.h: #include "libguile/threads-plugin.h". * threads.c: #include "libguile/threads-plugin.c". * pthread-threads.c: Temporarily remove debugging functions. * threads.c, threads.h (scm_yield): Added back. 2002-12-18 Mikael Djurfeldt * threads.c (really_launch): Detach before unlocking thread_admin_mutex in order not to risk being joined. (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep thread_admin_mutex locked during GC. * pthread-threads.c, pthread-threads.h: Improvements to debugging functions. 2002-12-16 Mikael Djurfeldt * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added support for debugging mutex operations. * threads.c (scm_thread): Removed filed joining_threads. (thread_print): Print thread number as well as address of thread structure. (scm_join_thread): Bugfix. (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex, scm_timed_wait_condition_variable, scm_signal_condition_variable, scm_broadcast_condition_variable): Use the low-level API. (scm_all_threads): Return copy of thread list (to prevent unintended destruction). (scm_threads_prehistory): Initialize heap_mutex of fake thread. * pthread-threads.c, pthread-threads.h, threads.c: Fixes to pthread "native" recursive mutex support. 2002-12-15 Mikael Djurfeldt * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions. Simply lock a thread C API recursive mutex. (SCM_NONREC_CRITICAL_SECTION_START, SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, SCM_REC_CRITICAL_SECTION_END): Removed. * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with direct calls to scm_rec_mutex_lock / unlock around the three calls to scm_m_expand_body. * eval.c, eval.h (promise_free): New function. (scm_force): Rewritten; Now thread-safe; Removed SCM_DEFER/ALLOW_INTS. * pthread-threads.h: Added partially implemented plugin interface for recursive mutexes. These are, for now, only intended to be used internally within the Guile implementation. * pthread-threads.c: New file. * threads.c: Conditionally #include "pthread-threads.c". * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be thread-safe; * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX, SCM_GLOBAL_REC_MUTEX): New macros. * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section macros---use mutexes instead. * tags.h (SCM_IM_FUTURE): New tag. * eval.c (scm_m_future): New primitive macro. (SCM_CEVAL): Support futures. (unmemocopy): Support unmemoization of futures. * print.c (scm_isymnames): Name of future isym. * version.c: Unmade some changes to my private copy that got committed by mistake. 2002-12-11 Mikael Djurfeldt * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of 2002-12-10. * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists. * gc.c (scm_gc_sweep): Call it here instead, which is a more logical place. * threads.c (create_thread): Remember root object until the handle of the new thread is on all_threads list. * root.c (scm_make_root): Moved copying of fluids until after creation of root handle so that the fluids are GC protected. Also removed the critical section. 2002-12-10 Mikael Djurfeldt * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function. * gc-malloc.c (malloc_mutex): New mutex. (scm_gc_malloc_prehistory): Initialize it. (scm_realloc): Serialize call to realloc (scm_calloc): Same for calloc. Thanks to Wolfgang Jaehrling! (Now we have to make sure all calls to malloc/realloc are made through scm_malloc.) * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory. * threads.c (really_launch): Release heap (to prevent deadlock). (create_thread): Release heap before locking thread admin mutex. 2002-12-10 Mikael Djurfeldt * threads.c (scm_i_thread_invalidate_freelists): New function. * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists. * modules.c (scm_export): Inserted a return statement. 2002-12-10 Han-Wen Nienhuys * modules.c (scm_export): new function * gc-card.c: add a note about malloc()/free() overhead. 2002-12-10 Mikael Djurfeldt * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c in srcdir. 2002-12-10 Mikael Djurfeldt These changes remove scm_ints_disabled (which hasn't has any effect in Guile for quite some time). * async.c, error.h (scm_ints_disabled): Removed. * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1), root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled. (old_ints): Removed. * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive critical section. (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and SCM_ALLOW_INTS. 2002-12-09 Mikael Djurfeldt * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait): Removed accidental #if 0 around these functions. These changes are the start of support for preemptive multithreading. Marius and I have agreed that I commit this code into the repository although it isn't thoroughly tested and surely introduces many bugs. The bugs should only be exposed when using threads, though. Signalling and error handling for threads is very likely broken. Work on making the implementation cleaner and more efficient is needed. * __scm.h (SCM_ALLOW_INTS_ONLY): Removed. (SCM_NONREC_CRITICAL_SECTION_START, SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, SCM_REC_CRITICAL_SECTION_END): New macros. (SCM_CRITICAL_SECTION_START/END): Defined here. * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around the three calls to scm_m_expand_body. * gc.h: #include "libguile/pthread-threads.h"; (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros. * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type scm_t_key; * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist access. * gc-freelist.c (scm_gc_init_freelist): Create freelist keys. * gc-freelist.c, threads.c (really_launch): Use SCM_FREELIST_CREATE. * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory): * gc.c (scm_i_expensive_validation_check, scm_gc, scm_gc_for_newcell): Put threads to sleep before doing GC-related heap administration so that those pieces of code are executed single-threaded. We might consider rewriting these code sections in terms of a "call_gc_code_singly_threaded" construct instead of calling the pair of scm_i_thread_put_to_sleep () and scm_i_thread_wake_up (). Also, we would want to have as many of these sections eleminated. * init.c (scm_init_guile_1): Call scm_threads_prehistory. * inline.h: #include "libguile/threads.h" * pthread-threads.h: Macros now conform more closely to the pthreads interface. Some of them now take a second argument. * threads.c, threads.h: Many changes. 2002-12-09 Mikael Djurfeldt * Makefile.am (version.h): Changed $^ --> $< in rule for version.h. 2002-12-08 Rob Browning * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now. (SCM_MINOR_VERSION): use @--@ substitution now. (SCM_MICRO_VERSION): use @--@ substitution now. (scm_effective_version): new function prototype. * version.c (scm_effective_version): new function, also add effective-version. * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION. (libpath.h): use GUILE_EFFECTIVE_VERSION to compute SCM_LIBRARY_DIR. (version.h): generate this here rather than configure.in. This approach tracks source edits better (i.e. more immediately). Might be worth considering for other .in files too. 2002-12-02 Marius Vollmer Reorganized thread package selection. A thread package now only implements a small set of pthread like functions and Guile implements the rest on top of that. Guile's implementation is what the "coop-pthreads" package has been previously. Support for "coop" threads has been removed until I get time to add it again. * Makefile.am (libguile_la_SOURCES): Removed iselect.c. (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c, null-threads.c, coop-pthreads.c. (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added pthread-threads.h. * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h. * threads.h: Do not include "libguile/coop-defs.h". Include "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed (previously deprecated) C level thread API prototypes. They are now in the thread package specific headers, "null-threads.h" and "pthread-threads.h". (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR): New. (scm_threads_init): Removed. (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END, SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter, SCM_I_THREAD_SWITCH_COUNT): Define here. (scm_single_thread_p): Removed. (scm_call_with_new_thread): Take two args directly instead of list of two args. (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA, SCM_SET_THREAD_LOCAL_DATA): Define here. * threads.c: Merged with "coop-pthreads.c". * null-threads.h: Implement pthread-like API as a set of macros. * pthread-threads.h: New, implement pthread-like API by deferring to pthread itself. * init.c (scm_init_guile_1): Do not call scm_init_iselect, which has been lost in the reorganization. 2002-12-01 Mikael Djurfeldt The following change makes it possible to move procedure application dispatch outside inner loops. The motivation was clean implementation of efficient replacements of R5RS primitives in SRFI-1. The semantics is clear: scm_trampoline_N returns an optimized version of scm_call_N (or NULL if the procedure isn't applicable on N args). Applying the optimization to map and for-each increases efficiency noticeably. For example, (map abs ls) is 8 times faster than before. * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types. * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions. * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions; (map, for-each): Handle also application on two args as a special case; Use trampolines. Other changes: * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o; (subr2oless): Removed. (scm_restricted_vector_sort_x): Use scm_return_first to keep the vector GC protected. * eval.c (check_map_args): Use scm_out_of_range_pos instead of scm_out_of_range. 2002-11-24 Dirk Herrmann * evalext.[ch] (scm_m_undefine, undefine): Deprecated. 2002-11-17 Mikael Djurfeldt * debug.c (scm_make_iloc): Added missing "return". 2002-11-17 Marius Vollmer * strports.c (scm_eval_string_in_module): Validate second arg to be a module. Thanks to Arno Peters! 2002-11-16 Dirk Herrmann * .cvsignore: remove goops.c 2002-11-16 Dirk Herrmann * modules.c (scm_env_top_level, scm_lookup_closure_module, module_variable, scm_module_lookup_closure, scm_module_transformer, scm_sym2var, scm_module_reverse_lookup, scm_system_module_env_p): Don't compare SCM values with C operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP over SCM_NFALSEP. 2002-11-16 Dirk Herrmann * eval.h (SCM_MAKE_ILOC): New macro. * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing the iloc bitpattern here. 2002-11-14 Mikael Djurfeldt * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be part of the API, otherwise it's difficult to write Guile extensions using non-blocking I/O => moved #include "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h. * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex --> s_unlock_mutex. 2002-11-10 Marius Vollmer * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They are defined in configure.in. * threads.c: Removed SCM_API from function definitions. SCM_API is only for declarations. 2002-11-07 Mikael Djurfeldt * coop-pthreads.h: Added support for thread specific data to the generic C API for the coop-pthreads case. * threads.c, threads.h (scm_cond_init): Undo unintentional API change. (scm_cond_broadcast): Added missing function. 2002-11-04 Marius Vollmer * coop.c (coop_next_runnable_thread): Removed, wich should have happened when GUILE_ISELECT was hard-wired. 2002-11-03 Marius Vollmer * Makefile.am (libguile_la_SOURCES): Added threads.c (DOT_DOC_FILES): Added threads.doc. (DOT_X_FILES): Added threads.x. (EXTRA_libguile_la_SOURCES): Removed threads.c. (noinst_HEADERS): Added coop-pthreads.c. (modinclude_HEADERS): Added coop-pthreads.h. * __scm.h (USE_THREADS, GUILE_ISELECT): Define when SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile. * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H. Thanks to Bill Schottstaedt! * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0. * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when SCM_COPT_THREADS is defined. (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS is defined. * coop-pthreads.c: Some harmless renamings of internal stuff. (create_thread): New, generalized version of scm_call_with_new_thread. (scm_call_with_new_thread): Use it. (scm_spawn_thread): New, use create_thread. 2002-11-02 Marius Vollmer * coop-pthreads.c, coop-pthreads.h: Redone completely, you might start testing it now. * _scm.h: Include * scmsigs.c (signal_cell_handlers, install_handler_data, scm_delq_spine_x, really_install_handler, install_handler): New scheme for triggering signal handlers, to simplify take_signal. (take_signal): Simplified, to avoid race conditions. (scm_sigaction_for_thread): Use new Scheme. Validate that thread hasn't exited yet. * async.c (scm_async_click): Reset pending_asyncs, handle signal_asyncs. Don't set cdr of a non-signal async to #f. (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue always. Set pending_asyncs. (scm_system_async_mark_for_thread): Check that thread has not exited. (scm_unmask_signals, decrease_block): Call scm_async_click after block_asyncs becomes zero. * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of active_asyncs. * root.h (scm_root_state): Added pending_asyncs and signal_asyncs fields. * root.c (root_mark): Mark them. (make_root): Initialize them. * iselect.c, iselect.h: Replaced GUILE_ISELECT with USE_COOP_THREADS. (scm_internal_select): Define one version for USE_COOP_THREADS and one for USE_NULL_THREADS. (scm_init_iselect): Likewise. * inline.h (scm_cell, scm_double_cell): Also allow USE_COPT_THREADS to not protect the slot initializers. * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is because threads need to be initialized before the stack, but gsubrs such as scm_timed_condition_variable_wait can only be created later. * threads.h: Include "coop-pthreads.h" when requested. (scm_threads_make_mutex, scm_threads_lock_mutex, scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were not implemented anyway.

(scm_init_scmsigs): Allocate signal_handler_cells and signal_handler_threads vectors. * async.c: Removed GUILE_OLD_ASYNC_CLICK code. Reorganized so that system asnycs and user asyncs are separated.

Thanks to Martin Grabmüller! 2002-08-25 Han-Wen Nienhuys * gc-segment.c (scm_i_get_new_heap_segment): use float in stead of unsigned numbers for computing minimum heap increment. This prevents weird results when a a negative minimum increment is computed. 2002-08-24 Marius Vollmer * gc_os_dep.c: When we have __libc_stack_end, use that directly instead of the old tricks. * guile-snarf.in: Do not expect the input file to be the first argument after the optional "-o" option, just pass everything to the pre-processor without extracting the input file name. 2002-08-23 Han-Wen Nienhuys * gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment length *at* least SCM_MIN_HEAP_SEG_SIZE, not at most. 2002-08-22 Han-Wen Nienhuys * gc.h, gc.c: make scm_cells_allocated unsigned again. Thanks to Bill Schottstaedt for the bug report 2002-08-20 Marius Vollmer * print.c (scm_iprin1): Print primitives generics always as "primitive-generic" even when they have no primitive methods yet. 2002-08-17 Gary Houston * coop.c (coop_create): removed bogus 2nd argument in scm_malloc call. 2002-08-17 Han-Wen Nienhuys * ports.c (scm_add_to_port_table): small bugfix. * mallocs.c (scm_malloc_obj): use scm_gc_malloc in stead of malloc. * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft: only use SCM_MIN_HEAP_SEG_SIZE. * ports.c (scm_add_to_port_table): add backwards compatibility function * ports.h: use scm_i_ prefix for port table and port table size. 2002-08-15 Mikael Djurfeldt * vports.c (scm_make_soft_port): Initialize pt variable. 2002-08-13 Marius Vollmer * strports.h (scm_c_eval_string_in_module, scm_eval_string_in_module): New prototypes. * strports.c (scm_eval_string_in_module): New, but use "eval-string" as the Scheme name and make second parameter optional. (scm_eval_string): Implement using scm_eval_string_in_module. (scm_c_eval_string_in_module): New. Thanks to Ralf Mattes for the suggestion! 2002-08-09 Han-Wen Nienhuys * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print message and abort. * gc-mark.c ("scm_gc_mark_dependencies"): idem. * ports.c ("scm_new_port_table_entry"): return a boxed SCM in stead of scm_t_port*. The function now takes a tag argument. 2002-08-08 Han-Wen Nienhuys * gc.h: add scm_debug_cells_gc_interval to public interface * gc-card.c ("sweep_card"): set scm_gc_running while sweeping. * gc.c (scm_i_expensive_validation_check): separate expensive validation checks from cheap ones. 2002-08-06 Han-Wen Nienhuys * read.c (scm_input_error): new function: give meaningful error messages, and throw read-error * gc-malloc.c (scm_calloc): add scm_calloc. 2002-08-05 Han-Wen Nienhuys * tags.h: remove GC bits documentation from the tags table. * read.c (INPUT_ERROR): Prepare for file:line:column error messages for errors in scm_lreadr() and friends. 2002-08-04 Han-Wen Nienhuys * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies implementation). (scm_gc_calloc): new function 2002-08-04 Han-Wen Nienhuys * ports.c (scm_new_port_table_entry): init port entry to 0 completely. * ports.c (scm_new_port_table_entry): change function from scm_add_to_port_table. This prevents cells with null-pointers from being exposed to GC. * vports.c (scm_make_soft_port) strports.c (scm_mkstrport), fports.c (scm_fdes_to_port): Use scm_new_port_table_entry(). * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic to gc-stats. * numbers.c (big2str): return "0" for 0 iso.

Note: The built-in syntax transformers that are named "mmacro" or "memoizing-macro" still exist, and it is these which come much closer to what one would call a macro. 2002-07-13 Neil Jerram * eval.c (unmemocopy): Fix for 1001-local-eval-error-backtrace-segfaults (unmemoization crash with internal definitions and local-eval). 2002-07-12 Gary Houston * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not defined. They don't do anything useful, especially since the only case where DYNAMIC_LINKING is undefined seems to be when --with-modules=no is given to configure, which is basically requesting that the "dynamic linking module" be omitted. * Makefile.am (libguile_la_SOURCES): move dynl.c from libguile_la_SOURCES to EXTRA_libguile_la_SOURCES. * extensions.c (load_extension): check DYNAMIC_LINKING for scm_dynamic_call. * init.c (scm_init_guile_1): check DYNAMIC_LINKING for scm_init_dynamic_linking. 2002-07-10 Marius Vollmer * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to check for Cygwin when including , this is already check for by configure. Thus, revert change from 2002-07-07. 2002-07-10 Gary Houston * eq.c: include * dynl.c: docstring editing. 2002-07-09 Gary Houston * dynl.c (scm_dynamic_call): docstring editing. 2002-07-08 Rob Browning * gc_os_dep.c: HURD fixes. 2002-07-07 Marius Vollmer Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks! * Makefile.am: Override default rule for c-tokenize.$(OBJECT); this should be compiled for BUILD host. Override default rule for guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host. Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation. (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile. * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include on Cygwin even when we have it. 2002-07-01 Dirk Herrmann * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args, SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up the code. Full number of arguments checking of closures is mandatory now. However, the option to disable the checking has most probably not been used anyway. 2002-06-30 Dirk Herrmann * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1, scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each), feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c (scm_source_properties, scm_set_source_properties_x, scm_source_property): Removed compile time option SCM_RECKLESS to clean up the code. Full number of arguments checking of closures is mandatory now. However, the option to disable the checking has most probably not been used anyway. * srcprop.c (scm_source_properties, scm_set_source_properties_x, scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP. 2002-06-30 Gary Houston * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't do anything useful. Added a comment about need for a mutex if pre-emptive threading is supported. * posix.c (scm_convert_exec_args), dynl.c (scm_make_argv_from_stringlist): static procs: 1) renamed both to allocate_string_pointers. 2) simplified: don't reallocate the strings, just make an array of pointers 3) avoid memory leaks on error 4) let the procedure report errors in its own name. Consequences: 1) the procedures now assume that SCM strings are nul-terminated, which should always be the case. 2) Since strings are not reallocated, it's now possible for strings passed to dynamic-args-call to be mutated. 2002-06-28 Dirk Herrmann * __scm.h, eval.c, eval.h: Removed compile time option MEMOIZE_LOCALS to clean up the code. Now, caching of local variable positions during memoization is mandatory. However, the option to disable the caching has most probably not been used anyway. 2002-06-18 Marius Vollmer * print.c (scm_simple_format): Print missing part of format before ~% control. Thanks to Daniel Skarda! 2002-06-01 Marius Vollmer * mkstemp.c: Added exception notice to license statement. 2002-05-22 Marius Vollmer * numbers.c (mem2ureal): When returning an inexact zero, make sure it is represented as a floating point value so that we can change its sign.

(scm_inexact_to_exact): Signal error when converting a NaN. 2002-05-06 Marius Vollmer * posix.c (scm_putenv): Handle removing variables explicitely by calling unsetenv. From John W. Eaton. * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf, and scm_nan. * numbers.c: [SCO && !

(iflo2str): Don't output a '+' for negative numbers or for Inf and NaN. They will provide their own sign. (scm_divide): Only allow divides by inexact zeros. Dividing by exact zeros still signals an errors. 2002-04-22 Thien-Thi Nguyen * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p. * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p. (scm_slot_exists_p): Rename from scm_slots_exists_p. Thanks to Andreas Rottmann. 2002-04-20 Gary Houston * removal of unused fields in root state (thanks to Christopher Cramer for pointing out the disuse.) * root.h (scm_root_state): removed def_inp, def_outp, def_errp.

This would write to the $(srcdir) during a VPATH build, which is not allowed. It also isn't needed since it only works when an output filename has been specified and in that case we don't need to clean the input file because the output file will already exist. 2002-03-31 Marius Vollmer * guile-snarf: Install the trap for removing $cleanfile only when the value of $cleanfile is actually known. 2002-04-10 Rob Browning * .cvsignore: add versiondat.h and *.c.clean.c. 2002-03-26 Dirk Herrmann * srcprop.[ch] (scm_c_source_property_breakpoint_p): New function, replaces macro SRCBRKP.

(SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting operation from condition. 2002-03-24 Marius Vollmer * guile-snarf.in: When the output filename is "-", write to stdout. When no "-o" option is given, use "-" as the output filename (i.e., stdout). Only 'clean' the inputfile or remove the output file on error when the output file name is not "-". Define the preprocessor macro SCM_MAGIC_SNARFER while snarfing. * Makefile.am (.c.x): Pass "-o $@" to guile-snarf. 2002-03-23 Dirk Herrmann * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs and the corresponding goto statements.

Removed some uses of arg1 and arg2 as temporary variables. 2002-03-15 Thien-Thi Nguyen * guile-snarf.in: Remove "--compat=1.4" support. Add "-d" and "-D" support. (deprecated_list): New var. (compat_mode_clean_xxx): Delete. (grep_deprecated): New func.

Docstring fixes: * strings.c (scm_string_p): Change unnecessary `iff' to `if'. * ports.c (scm_sys_make_void_port): Use `@file'. * numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather than `else'. * macros.c (scm_makmacro): Don't say that the form replaces its source, because it doesn't. (scm_makmmacro): Clarify difference between this and scm_makmacro. * backtrace.c (scm_display_error), filesys.c (scm_umask, scm_select, scm_basename), goops.c (scm_method_generic_function), numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl, scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct spelling mistakes. * debug.c (scm_debug_options), eval.c (scm_eval_options_interface), read.c (scm_read_options): Change incorrect @var in docstring to @code. 2002-03-14 Marius Vollmer * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP. * snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that guile-snarf can remove trailing non-init code. * guile-snarf.in (modern_snarf): Remove everything following and including "^:^" from the output. 2002-03-14 Dirk Herrmann * eval.c (SCM_CEVAL), srcprop.h (SRCBRKP): Eliminated union 't'. * eval.c (SCM_CEVAL): Exlined call to EVALCAR. 2002-03-13 Thien-Thi Nguyen * guile-snarf.in: Update copyright.

The next step will be to remove the union 't' and simplify the code of SCM_CEVAL that way. 2002-03-12 Neil Jerram * iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds, rreadfds, rwritefds, rexceptfds): Made static. * gc.c (terminating), fports.c (terminating): Renamed scm_i_terminating. 2002-03-11 Marius Vollmer * numbers.c (scm_divide): Adapt code from libstdc++/f2c to void potential overflow problems. Thanks to John W Eaton! * strop.c (string_capitalize_x): Treat characters as unsigned so that 8-bit chars work. Thanks to David Pirotte! 2002-03-10 Dirk Herrmann * eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref', 'slot-set!' and 'nil-cond'. Removed some uses of t.arg1, arg2 and proc as temporary variables. Introduced temporary variables with hopefully descriptive names for clarification. Replaced SCM_N?IMP by a more explicit predicate in some places. 2002-03-09 Dirk Herrmann * eval.c (SCM_CEVAL): Cleaned up the handling of #@dispatch. Added lots of comments regarding the implementation of #@dispatch. Changed intra-procedure communication to use t.arg1 instead of arg2.

It isn't needed, and it can overflow the bits reserved for it (which may lead to a segv or a GC abort). 2002-03-02 Dirk Herrmann * eval.c (SCM_CEVAL): Cleaned up the handling of 'apply'. Removed side-effecting operations from conditions and macro calls. Replaced SCM_N?IMP by a more explicit predicate in some places.

(scm_deprecated_newcell, scm_deprecated_newcell2): New. * inline.c, inline.h: New files. * Makefile.am: Added them in all the right places. * _scm.h: Include "libguile/inline.h". * alist.c, coop-threads.c, debug.c, environments.c, eval.c, fports.c, gh_data.c, goops.c, guardians.c, lang.c, list.c, num2float.i.c, numbers.c, pairs.c, ports.c, print.c, procs.c, smob.c, smob.h, strings.c, strports.c, struct.c, symbols.c, unif.c, variable.c, vectors.c, vports.c, weaks.c: Replaced SCM_NEWCELL and SCM_NEWCELL2 with scm_alloc_cell and scm_alloc_double_cell, respectively. 2001-11-23 Marius Vollmer * modules.c (scm_c_use_module): Adapt to changes to `process-use-modules'. 2001-11-22 Dirk Herrmann * numbers.c (scm_divide): Fix more division by zero errors. 2001-11-21 Gary Houston * Makefile.am (OMIT_DEPENDENCIES): removed, since it seems to be obsolete. autogen.sh says: invalid unused variable name: `OMIT_DEPENDENCIES' 2001-11-22 Dirk Herrmann * numbers.c (scm_divide): Fix (/ 0). Thanks to Keith Wright for reporting the bug. 2001-11-21 Marius Vollmer * Makefile.am (install-exec-hook): Prepend $(DESTDIR) to filename. Thanks to Eric Gillespie, Jr! 2001-11-21 Stefan Jahn * win32-socket.c (getservent, setservent, endservent, getprotoent, setprotoent, endprotoent): New functions. Appropriate replacements for M$-Windows. * numbers.c (SIZE_MAX, PTRDIFF_MAX, PTRDIFF_MIN): Reintroduced these definitions for GUILE_DEBUG. * net_db.c: Include "win32-socket.h" if compiling with a native M$-Windows compiler. Include some pieces of code (protoent and servent interface) protected by HAVE_* macros when using a native M$-Windows compiler. 2001-11-20 Marius Vollmer * modules.c (scm_c_export): Do nothing when the first argument is already the terminating NULL. Thanks to Han-Wen Nienhuys! 2001-11-20 Thien-Thi Nguyen * Makefile.am (libpath.h): In SCM_BUILD_INFO, also include `buildstamp'. 2001-11-18 Rob Browning * version.c (s_scm_major_version): use SCM_MAJOR_VERSION. (s_scm_minor_version): use SCM_MINOR_VERSION. (s_scm_micro_version): use SCM_MICRO_VERSION. (s_scm_version): use SCM_MAJOR_VERSION, SCM_MINOR_VERSION, and SCM_MICRO_VERSION. * version.h.in (SCM_MAJOR_VERSION): renamed from SCM_GUILE_MAJOR_VERSION. (SCM_MINOR_VERSION): renamed from SCM_GUILE_MINOR_VERSION. (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION. 2001-11-18 Neil Jerram * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x): Rewrite docstrings without reference to substring-move-left/right, since the latter no longer exist. 2001-11-17 Dirk Herrmann * eval.c: Removed bogus comment about acros. (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP. Minimize scope of local variable. Eliminate dependency on macro DEBUG_EXTENSIONS. (s_splicing): New error message string. (scm_m_body): Issue 'bad body' message rather than 'missing expression' message. (scm_m_quote): Eliminate unnecessary copying. (scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the checking of the body to scm_m_body. (scm_m_do): Move comment to function header. Rename arg1 to binding. Made the code a bit easier to read. (evalcar): Removed. (iqq): Added a comment. Changed the depth parameter to unsigned. Use size_t for vector lengths. Make sure vector object is gc protected as long as its contents are read. Add some syntax checks. Get rid of unnecessary SCM_IMP test. Clean up the control structure a bit. (scm_m_delay): Added comment about the implementation of scm_m_delay. (scm_m_define): Add comment about guile's currying define syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code. (scm_m_letrec1): Removed. Part of the functionality is taken over by the new function 'transform_bindings'. (transform_bindings): New function. Takes over some of the functionality of removed function 'scm_m_letrec1', namely to split a list of bindings into a reversed list of variables and a list of initializers. (scm_m_letrec): Call 'transform_bindings'. (scm_m_let): Minimized scope of local variables. Renamed 'proc' to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP test. Use 'transform_bindings'. Fixed scoping error with named let (Thanks to Aubrey Jaffer for reporting the bug and to Neil Jerram for suggesting the fix). Cleaned up the control structure a bit. (scm_m_expand_body): Use 'transform_bindings'. Eliminated unnecessary consing. Eliminated unnecessary SCM_DEFER/ALLOW_INTS. (SCM_CEVAL): Un-obfuscated some loops. 2001-11-16 Neil Jerram * gc.h (scm_unhash_name): Old declaration removed. * eval.c (s_scm_eval): Change @var{primitive-eval} to @code{primitive-eval}. * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c, version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c: Change @deffnx lines in docstrings to say {Scheme Procedure} rather than primitive or procedure. * posix.c (scm_execl), filesys.c (scm_close), unif.c (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x, scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x, scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector, scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c (scm_string_split, scm_string_ci_to_symbol), strings.c (scm_string_p), sort.c (scm_merge), print.c (scm_newline), macros.c (scm_macro_type), alist.c (scm_acons, scm_assq): Docstring fixes and improvements reflecting edits that have been made in the reference manual source. * objprop.c (scm_object_properties, scm_set_object_properties_x, scm_object_property, scm_set_object_property_x): Remove invalid @deffnx lines for corresponding procedure property primitives. These changes add a @deffnx C function declaration and function index entries for each Guile primitive to the copy of the doc snarf output that is used for reference manual synchronization. Online help is unchanged. * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name. (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function name to SCM_SNARF_DOCS. * guile-snarf-docs-texi.in: Pass the shell script's arguments into snarf-check-and-output-texi. * Makefile.am (guile-procedures.texi): New rule. (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES): Changed so that the last stage of doc snarfing is now performed twice, once to produce guile-procedures.txt for online help, and once to produce guile.texi for reference manual synchronization. 2001-11-15 Dirk Herrmann * eval.c (RETURN): Wrap in do{}while(0) in order to make it safely usable as a single statement followed by a ';', for example in an if statement. (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'. 2001-11-13 Neil Jerram * random.c (scm_random_solid_sphere_x, scm_random_hollow_sphere_x): Correct "shere" typos. * hashtab.c (scm_hash_fold): Add missing apostrophe to docstring. * version.c (scm_version): Update docstring to include `micro-version'. 2001-11-13 Marius Vollmer * modules.c (scm_c_export): Call va_end after collecting the symbols. * strop.h, strop.c (scm_substring_move_left_x, scm_substring_move_right_x): Removed. * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG, HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what configure does. 2001-11-12 Marius Vollmer * numbers.c: Document macros to define when including num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we now rely on SIZEOF_ macros that have been figured out at configure time. * num2integral.i.c: Adapt to new interface. (NUM2INTEGRAL): Test whether a fixnum can be represented in the target type by casting it and checking whether it is still the same. Do not try to handle bignums for integral types that are smaller than fixnums. When handling bignums, collect the magnituse first into a unsigned type, and correctly check for overflow. (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that only -MIN_VALUE can still be negative of all negative numbers (in twos-complement). * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately. * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and HAVE_LONG_LONG depending on whether their size is non-zero. 2001-11-11 Thien-Thi Nguyen * strop.c (scm_string_null_p): Docfix; nfc. Thanks to Scott Lenser. 2001-11-07 Neil Jerram * extensions.c (scm_load_extension): Canonicalize docstring whitespace. * unif.c (scm_uniform_array_write), ports.c (scm_current_output_port, scm_force_output), dynwind.c (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer), filesys.c (scm_open, scm_lstat), struct.c (scm_make_struct_layout), random.c (scm_random, scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c (scm_i_index): Remove superfluous whitespace from end of docstring lines. * filesys.c (scm_select), guardians.c (scm_guardian_greedy_p), strings.c (scm_make_string), variable.c (scm_make_variable, scm_make_undefined_variable, scm_variable_p, scm_variable_set_x, scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer), posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous newline at end of docstrings. * modules.c (scm_set_current_module): Add missing newline to docstring. 2001-11-07 Stefan Jahn * win32-socket.[ch]: New files. Defines Winsock-API error codes and makes them available through Guile. That is because the Winsock-API does not store its errors in `errno' and thus cannot return error messages via `strerror (errno)'. * socket.c (scm_init_socket): Initialize `win32-socket' part here under M$-Windows. * numbers.h: Added missing declaration of `scm_sys_check_number_conversions()'. * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO and use in `(strerror)' and `(system-error)'. * Makefile.am (EXTRA_libguile_la_SOURCES): Added `win32-socket.[ch]' to extra source and header files. 2001-11-06 Marius Vollmer * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend a call to turn-on-debugging when --debug has been given instead of turning it on directly. Also, handle new `--no-debug' option, which might suppress the call to turn-on-debugging. 2001-11-05 Stefan Jahn * struct.c (s_scm_struct_vtable_p): Corrected docstring. 2001-11-04 Stefan Jahn * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL) here (was at guile_LDADD) which describes the dependency correctly and allows a clean build on Win32. * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros into FOO. * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL import macros for external libraries (libcrypt, libqthreads, libreadline and libregex). * coop-defs.h: Include for `struct timeval'. * posix.c (flock): Added support for flock() in M$-Windows. * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead of __SCM_IMPORT__. * fports.c (getflags): Differentiate reading and writing pipes descriptors. * filesys.c (S_IS*): Redefine all of the S_IS*() macros for M$-Windows. * coop.c (coop_condition_variable_timed_wait_mutex): Use conditionalized error code if `ETIMEDOUT' is not available. (scm_thread_usleep): Remove bogus declaration of `struct timeval timeout'. * numbers.c (PTRDIFF_MIN): Moved this definition where it actually belongs. That is because NO_PREPRO_MAGIC gets undefined after each inclusion of `num2integral.i.c'. (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined. 2001-11-03 Marius Vollmer * eval.c (scm_m_begin): Allow `(begin)`, with no subforms. (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED. 2001-11-02 Mikael Djurfeldt * print.c (scm_iprin1): Mark print state as revealed when dispatching to generic write or display. * unif.c (scm_ra2contig): Fixed memory overwrite bug. 2001-11-02 Marius Vollmer Support for native Win32. Thanks to Stefan Jahn! * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c and win32-dirent.h to extra source and header files. These include the uname() and the POSIX dirent interface implementation for M$-Windows. Put `-no-undefined' into LDFLAGS to support linkers which do not allow unresolved symbols inside shared libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)' dependency. * __scm.h: Defined SCM_API. This macro gets prepended to all function and data definitions which should be exported or imported in the resulting dynamic link library in the Win32 port. * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h, chars.h, continuations.h, coop-defs.h, coop-threads.h, debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h, environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h, feature.h, filesys.h, fluids.h, fports.h, gc.h, gdb_interface.h, gdbint.h, gh.h, goops.h, gsubr.h, guardians.h, hash.h, hashtab.h, hooks.h, init.h, ioext.h, iselect.h, keywords.h, lang.h, list.h, load.h, macros.h, mallocs.h, modules.h, net_db.h, numbers.h, objects.h, objprop.h, options.h, pairs.h, ports.h, posix.h, print.h, procprop.h, procs.h, properties.h, ramap.h, random.h, rdelim.h, read.h, regex-posix.h, root.h, rw.h, scmsigs.h, script.h, simpos.h, smob.h, socket.h, sort.h, srcprop.h, stackchk.h, stacks.h, stime.h, strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h, tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h, vports.h, weaks.h: Prefixed each each exported symbol with SCM_API. * continuations.c: Added comment about the use of the extern declarations of {get,set}context() functions used in the ia64 port. * continuations.h, gc.c: `__libc_ia64_register_backing_store_base' is meant to be a `unsigned long *'. * filesys.c: Include `direct.h' if possible. Use local `win32-dirent.h' for the native M$-Windows port. Define S_IS*() macros for M$-Windows. Implementation of `fstat_Win32()' which is able to differentiate between sockets and other file descriptors. Use this function as wrapper in `scm_fstat()'. Fixed typo in `scm_dirname()'. * fports.c: Include `io.h' is possible. Put `*fp' into referring statement block in `scm_fport_buffer_add()'. Some corrections in `getflags()'. * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__. * guile.c: Make sure to define __SCM_IMPORT__ for shared library build on Win32. Disable preloaded symbols on Win2 platforms. * ioext.c, ports.c: Include `io.h' is possible. * mkstemp.c: Include `process.h' is possible. * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__, too. Put `scm_return_entry()' into HAVE_GETSERVENT conditional. * posix.c: Remove unnecessary dirent includes and defines. Include local `win32-uname.h' for MinGW. Extern declaration of `mkstemp()' for systems where it does not exists. Make `getlogin()' available on M$-Windows. * scmsigs.c: Made `usleep()' avalable on MinGW. * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'. * win32-dirent.c: Include "win32-dirent.h", not "dirent.h". * win32-uname.c: Include "win32-uname.h", not "uname.h". 2001-10-28 Mikael Djurfeldt * unif.c (scm_uniform_array_read_x, scm_uniform_array_write): Don't apply scm_uniform_vector_length on arrays. 2001-10-14 Dirk Herrmann * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq, scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body, scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args, SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer scm_list_ over scm_cons[2]?. (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1, scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_C[AD][AD]R instead of explicit form. (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered comparison parameters. (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use !SCM_NULLP instead of SCM_NIMP. (scm_m_case): Don't copy the form. Renamed proc to clause and minimized its scope. Renamed x to clauses. Removed side effecting operation from macro call. (scm_m_cond): Don't copy the form. Renamed arg1 to clause and minimized its scope. Renamed x to clauses. Minimized the scope of variable 'len'. Make sure the else clause is treated specially even in case of '=>' occurences. Don't change the else to #t in order to be able to distinguish this case in the evaluator. Leave type checking of the recipient to the evaluator. (scm_c_improper_memq): Made the comment somewhat clearer. (scm_m_lambda): Renamed proc to formals. Removed unnecessary test for SCM_IM_LET at the place of the formal parameters. Simplified the formal parameter checking. (scm_m_letstar): Added Comment. Renamed proc to bindings. Renamed arg1 to binding and minimized its scope. Eliminated unnecessary consing. (scm_m_do): Renamed proc to bindings. Minimized the scope of variable 'len'. (build_binding_list): New static function. (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean). Further, split up the 'letrec' unmemoizing code to the corresponding parts for 'do', 'let' and 'letrec', adding comments to each form. Cleanup the handling of the do form (This removes some *real* code :-). (SCM_CEVAL): Removed side effecting operation from macro call. Handle the 'else clause of the 'cond form specially - the symbol 'else is not replaced with #t any more. 2001-10-14 Gary Houston * version.c (scm_version): use sprintf instead of snprintf, for portability. thanks to Bill Schottstaedt. 2001-10-14 Mikael Djurfeldt * read.c (scm_lreadr): When user-defined hash procedure returns SCM_UNSPECIFIED: Fall back to standard handling instead of raising an exception. (This prevents parsing of uniform vectors from interfering with parsing of numbers.) 2001-10-13 Marius Vollmer * numbers.c: Set NO_PREPRO_MAGIC when defining our version of PTRDIFF_MIN. Thanks to Ken Raeburn. 2001-10-07 Marius Vollmer * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c". * eval.c (scm_m_atbind): First try to find the variable without defining it locally; when it has not been found, define it locally. * modules.c (module_variable): Pass over variables that exist but are unbound. 2001-10-06 Marius Vollmer * backtrace.c (display_backtrace_file_and_line): Only use scm_basename when POSIX support is compiled in. Thanks to Chris Cramer. 2001-10-13 Dirk Herrmann * numbers.c (mem2uinteger): Return number read so far when coming across a hexdigit after having read a # or if not reading a hex value. This will enable the calling code to correctly handle forms like 1e2. (The background is, that the exponent markers d, e and f are also hexdigits.) Thanks to Mikael Djurfeldt for providing this patch. (mem2complex): Fix erroneous double-negation. Now, numbers like 1-i will be read correctly. 2001-10-12 Mikael Djurfeldt * debug.c (scm_mem_to_proc): Fixed typo in previous change. * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro. 2001-10-12 Dirk Herrmann * print.c (scm_print_state_vtable, print_state_pool): Initialize. These variables are now registered as gc roots. (scm_current_pstate): Update documentation. (scm_current_pstate, scm_make_print_state, scm_free_print_state, scm_prin1, scm_init_print): print_state_pool is registered as a gc root and thus does not need to be protected by a surrounding pair any more. (make_print_state): The car of print_state_pool no longer holds the scm_print_state_vtable. (scm_current_pstate, scm_make_print_state, print_circref, scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_ over SCM_N. (scm_prin1): When building lists, prefer scm_list_ over scm_cons[2]?. (scm_iprlist): Removed a redundant SCM_IMP test. (scm_simple_format): Use SCM_EQ_P to compare SCM values. 2001-10-11 Dirk Herrmann * debug.c (scm_make_iloc): Prefer !SCM_ over SCM_N. (scm_memcons, scm_mem_to_proc): When building lists, prefer scm_list_ over scm_cons[2]?. (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP. (scm_procedure_name): Use SCM_CADR instead of explicit form. (debugobj_print): Coerce scm_intprint arg 1 to long, not int. Thanks to Rob Browning for the patch (see log entry 2001-09-21) - for some reason his patch didn't make it into the cvs. 2001-10-09 Dirk Herrmann * numbers.c (mem2decimal_from_point): Cleaned up the parsing a little bit - should even be somewhat more accurate now. 2001-10-08 Rob Browning * gc.c: support ia64 register backing store. (SCM_MARK_BACKING_STORE): new macro. * continuations.h: support ia64 register backing store. (struct scm_t_contregs): add ia64 register backing store. * continuations.c: support ia64 register backing store. (continuation_mark): mark ia64 register backing store. (continuation_free): free ia64 register backing store. (scm_make_continuation): capture ia64 register backing store. (copy_stack_and_call): copy ia64 register backing store. 2001-10-08 Dirk Herrmann * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn is known to be #f if no entry is found. Thus, use !SCM_FALSEP instead of SCM_NIMP to test for that case. * strings.h (SCM_SET_STRING_LENGTH): Cast the length to scm_t_bits instead of long. 2001-10-06 Marius Vollmer * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX, SCM_T_SIGNED_BITS_MIN): New. * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Use them to make these macros computable by the preprocessor. * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test whether the integral type fits in a fixnum, not the compiler. This removes a spurious compiler warning. Also, honor the NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is needed for `long long's. * numbers.c: Define NO_PREPRO_MAGOC when including num2integral.c.i for `long long' and `signed long long'. 2001-10-06 Mikael Djurfeldt These changes fixes a race condition in the Guile coop - pthread compatibility code. * coop.c (mother_awake_p): New variable. (coop_create): Set mother_awake_p before creating or signalling mother; wait until mother is going to sleep before returning. (mother): Reset mother_awake_p before going to sleep. 2001-10-05 Dirk Herrmann * options.c (protected_objects, scm_init_options): The content of protected_objects is now protected from garbage collection using scm_gc_register_root instead of scm_permanent_object. (get_option_setting): New static function that computes an option setting as it was formerly done in the function scm_options. (get_documented_option_setting): New static function that returns option documentation as it was formerly done in the function scm_options. Note that documentation C strings are no longer precomputed into SCM objects. Instead, they are converted into SCM strings every time get_documented_option_setting is called. (change_option_setting): New static functions that modifies the option setting as it was formerly done in the function scm_options. The function is now exception safe, i. e. won't cause a memory leak when interrupted. Further, only non-immediate option values are added to the protection list. (scm_options): This function now has only the purpose to dispatch to to get_option_setting, get_documented_option_setting or change_option_setting, depending on the arguments given to scm_options. (scm_init_opts): Don't convert documentation C strings into SCM strings. Further, don't protect any object values: They _must_ be immediate values, otherwise there is no guarantee that they have not been collected before anyway. * options.[ch] (scm_t_option): Made type unsigned, name into a constant char* and val into a scm_t_bits type. (scm_options, scm_init_opts): The number of options is guaranteed to be larger or equal to zero. Thus, the type is changed to unsigned. 2001-10-05 Dirk Herrmann * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about testing an unsigned value for being >= 0. 2001-10-05 Dirk Herrmann * numbers.h: Removed old comment about using SCM_CAR to access non-pair cells. (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure the return value is signed. Thanks to Brian Crowder for the bug report. (SCM_SRS): Avoid unnecessary casting and don't unpack input values. With this patch, SCM_SRS can be safely used for other types than scm_t_signed_bits. However, it should still better be an internal macro and thus be renamed to SCM_I_SRS. (SCM_MAKINUM, SCM_INUM): Use proper casting. 2001-10-03 Gary Houston * continuations.h, unif.h: in the descriptions of the bit patterns of the heap cells, make bit 0 the least significant. 2001-09-25 Thien-Thi Nguyen * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'. Thanks to Golubev I. N. 2001-09-25 Gary Houston * ports.c (scm_drain_input): extended the docstring. thanks to Alex Schroeder and Thien-Thi Nguyen. 2001-09-23 Mikael Djurfeldt * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE, SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New macros. (The NUM names might soon change.) * numbers.h: Added missing declarations. 2001-09-22 Mikael Djurfeldt * Makefile.am: Distribute num2float.i.c. * num2float.i.c: New file, multiply included by numbers.c, used to "templatize" the float <-> num conversion routines. * numbers.c: New functions: scm_num2float, scm_float2num, scm_num2double, scm_double2num. 2001-09-21 Rob Browning * .cvsignore: really add version.h * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long. Otherwise it fails on the alpha. However, we might rather choose this size conditionally. * numbers.c (scm_gcd): change "k" to a long from an int. Otherwise it fails on the alpha. However, we might rather choose this size conditionally. * error.c (scm_wta): coerce char* to intptr_t before int assignment. * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not int. * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t. 2001-09-20 Mikael Djurfeldt * numbers.c (scm_integer_expt): Accept inexact integer in second argument. (Thanks to Bill Schottstaedt.) 2001-09-20 Rob Browning * .cvsignore: add version.h * versiondat.h.in: removed (obsolete). * version.h.in: renamed from version.h. (SCM_GUILE_MAJOR_VERSION): new public macro. (SCM_GUILE_MINOR_VERSION): new public macro. (SCM_GUILE_MICRO_VERSION): new public macro. * version.h: renamed to version.h.in. * version.c (scm_major_version): support integer *_VERSION macros. (scm_minor_version): support integer *_VERSION macros. (scm_micro_version): support integer *_VERSION macros. (scm_version): support integer *_VERSION macros. 2001-09-20 Mikael Djurfeldt * error.c, error.h: Made error keys globally accessible. Applications might want to test for these or use them in a direct call to scm_error. * num2integral.i.c (NUM2INTEGRAL): Report an error when these routines are passed an inexact. This change in behavior is motivated by concordance with R5RS: It is more common that a primitive doesn't want to accept an inexact for an exact. 2001-09-17 Dirk Herrmann The following patch partially undoes my patch from 2001-06-30, where I added the function scm_gc_mark_cell_conservatively. The function is buggy, since it breaks guile during conservative marking if a pointer on the stack points directly into the list of free cells on the heap: With conservative cell marking this will cause the whole free list to be scanned and marked - boom! * gc.c (allocated_mark, MARK, heap_segment, scm_gc_mark_cell_conservatively, scm_init_storage), gc.h (scm_gc_mark_cell_conservatively): Remove function scm_gc_mark_cell_conservatively and update the corresponding comments and uses accordingly. Thanks to Christopher Cramer for the patch. (Minor corrections by me.) 2001-09-15 Gary Houston * root.h (scm_root_state): removed the continuation_stack and continuation_stack_ptr members, which have no apparent purpose. (scm_continuation_stack, scm_continuation_stack_ptr): #defines removed. * root.c (root_mark), init.c (restart_stack, start_stack), gc (scm_igc): remove all references to contination_stack and continuation_stack_ptr, avoiding allocation of a vector and useless processing during gc. 2001-09-13 Dirk Herrmann * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc. (TCONC_IN): Make sure that the cell word 0 is initialized last. (guardians_t, t_guardians): Renamed guardians_t to t_guardians. (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA. (guardian_apply, scm_get_one_zombie, scm_make_guardian, mark_and_zombify): Prefer !SCM_ over SCM_N. 2001-09-13 Dirk Herrmann * guardians.c (mark_dependencies_in_tconc, whine_about_self_centered_zombies, scm_init_guardians): Register the static global variable `self_centered_zombies' via scm_gc_register_root, to make some cdr-ing unnecessary. 2001-09-13 Dirk Herrmann * backtrace.c (display_backtrace_file, display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM values, use SCM_FALSEP when comparing SCM values against #f. Thanks to Rob Browning for the bug report. 2001-09-12 Martin Baulig * strings.[ch] (scm_str2string): New function. 2001-09-06 Marius Vollmer * gc.c (scm_done_free): Always subtract size from scm_mallocated when computing nm, even if it's negative. (scm_must_malloc): Abort on overflow of scm_mtrigger. (scm_must_realloc): Likewise. 2001-09-01 Michael Livshin * numbers.c (scm_sys_check_number_conversions): new function, defined if Guile is compiled in debugging mode. currently checks `scm_num2ulong', should check much much more. * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to unsigned, ensure that it's positive. thanks to Martin Baulig! 2001-08-31 Dirk Herrmann * __scm.h: Added new section about compile time selectable features. (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed. * deprecation.c (scm_include_deprecated_features): Simplified. * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use `SCM_IMP' instead of `!SCM_CELLP´. * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests. Extract side-effecting operations from macros. (scm_init_eval): Don't initialize *top-level-lookup-closure*, scm_top_level_lookup_closure_var and scm_system_transformer. * gc.c (CELL_P): New local definition to replace SCM_CELLP.

Further, got rid of a redundant SCM_NIMP test. 2001-06-30 Dirk Herrmann * list.c (SCM_I_CONS): Make sure the cell type is initialized last. * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep, init_heap_seg): Fixed signedness. (init_heap_seg): Replaced strange for-loop with a while loop. * weaks.h (WEAKSH, SCM_WEAKS_H): Rename H to SCM__H. (SCM_WVECTP): Prefer !SCM_ over SCM_N. The following patch adds conservative marking for the elements of free or allocated cells. * gc.c (allocated_mark, heap_segment): New static functions. (which_seg): Deleted, since the functionality is now provided by function heap_segment. (map_free_list): Use heap_segment instead of which_seg. (MARK): If cell debugging is disabled, mark free cells conservatively. (scm_mark_locations, scm_cellp): Extracted the search for the heap segment of a SCM value into function heap_segment.

(scm_gc_sweep): Weak vectors don't have extra fields any more. * weaks.c (allocate_weak_vector): New static function. It does not patch any previously created vector object during the construction of a weak vector, and thus doesn't need to switch off interrupts during vector creation. (scm_make_weak_vector, scm_make_weak_key_hash_table, scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table): Use allocate_weak_vector to provide the new weak vector object. * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE, SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is now stored in the double cell. (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY): Use SCM_WVECT_TYPE.

(EXTRA_DIST): add c-tokenize.lex, so it gets distributed. filter-doc-snarfage.c: remove. 2001-06-26 Martin Grabmueller * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT. The following set of changes makes compiling Guile under various Windows compilers easier. Compilation under GNU systems should not be affected at all.

This fix is not optimal, since it won't work reliably if sizeof (c_start) > sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better solution is to define this macro as an inline function, thus allowing to specifiy the types of c_start and c_end. 2001-06-25 Dirk Herrmann * debug.h (SCM_DEBUGOBJ_FRAME): Deliver result as a scm_t_debug_frame*. * debug.h (DEBUGH, SCM_DEBUG_H), stacks.h (STACKSH, SCM_STACKSH): Rename H to SCM__H. * stacks.c (NEXT_FRAME, narrow_stack): Prefer explicit type check over SCM_N?IMP, !SCM_ over SCM_N.

Livshin * backtrace.c (display_backtrace_body): since the `print_state' variable is not used (instead its data field is used directly as `pstate'), protect it from the hungry compiler optimizations. thanks to Bill Schottstaedt for the report. 2001-03-30 Dirk Herrmann * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells. It is only defined and used if guile is compiled with SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never let cells with a free_cell type tag be visible outside of the garbage collector when in debug mode. * gc.c (scm_debug_cell_accesses_p): Set to true as default. (scm_assert_cell_valid): Use a local static variable to avoid recursion. (MARK): Only check for rogue cell pointers in debug mode. Use scm_cellp for this purpose and place all checks for rogue pointers into that function. Further, since due to conservative scanning we may encounter free cells during marking, don't use the standard cell type accessor macro to determine the cell type. (scm_cellp): Check if the cell pointer actually points into a card header. (scm_init_gc): Initalize scm_tc16_allocated. * gc.h (GCH): Renamed to SCM_GC_H. (SCM_VALIDATE_CELL): Enclose the expression in brackets. This might be unnecessary, but I feel better this way :-) (SCM_GC_CELL_TYPE): New macro. (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used in guile, and it is unlikely that they will be applied to real pairs anyway. (SCM_SET_FREE_CELL_TYPE): Removed. It was not used. (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is compiled with SCM_DEBUG_CELL_ACCESSES set to true. (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will make sure that in debug mode no free cell will ever be visible outside of the garbage collector. 2001-03-30 Dirk Herrmann * async.c (scm_asyncs_pending): Don't use != to compare SCM values. * async.c (scm_system_async), variable.c (scm_make_variable, scm_make_undefined_variable): Use scm_cons to create a pair. * debug.c (scm_reverse_lookup): Perform proper type checking. Remove suspicious use of SCM_SLOPPY_CONSP. * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead of SCM_SLOPPY_CONSP.

It is declared in macros.h. * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and SCM_VARIABLE_H. Even the macros that are used to inhibit including a header file twice should be in the SCM_ namespace. * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse), properties.c (scm_primitive_property_ref, scm_primitive_property_del_x): Prefer stronger predicates like SCM_NULLP or SCM_FALSEP over SCM_IMP. * gc.c (MARK): Use proper macros to access procedure-with-setter cell elements and closure cell elements. (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't access free cells as pairs. (scm_unprotect_object): scm_hashq_get_handle returns #f if no hashtab entry is found. * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro SCM_CLR_PORT_OPEN_FLAG. * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't use SCM_SET_C[AD]R for uninitialized cells. * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR. If the hashtable has no slots, return #f instead of '(). This unifies the return value with most assoc-functions. (scm_hash_fn_ref): Use proper type check. (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle): Removed references to non-existing functions from documentation. * keywords.c (scm_keyword_dash_symbol): Use proper macros to access keyword cell elements. * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New macros. * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro. * print.c (scm_iprlist): Added comment. Improved loop conditions. * procs.h (SCM_ENV, SCM_SETENV): Don't access closure cells as pairs. * smob.c (scm_markcdr): Don't access smob cells as pairs. * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated. * throw.c (ACTIVATEJB, DEACTIVATEJB): Don't access jump buffer cells as pairs. * variable.c (variable_print, variable_equalp, scm_variable_ref, scm_variable_set_x): Use proper macros to access variable cell elements. (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL. * variable.h (SCM_VARVCELL): Don't access variable cells as pairs. * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified, added FIXME comment, removed register specifier. 2001-03-29 Keisuke Nishida * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated. * init.c (scm_init_guile_1): Don't init goopscore module. 2001-03-27 Marius Vollmer * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr. 2001-03-27 Martin Grabmueller * strop.c (scm_string_to_list): Fixed docstring markup. (scm_string_upcase_x, scm_string_upcase, scm_string_downcase_x), (scm_string_downcase, scm_string_capitalize_x), (scm_string_capitalize): Rewrote and corrected docstrings.

(scm_init_posix): [PRIO_PROCESS, PRIO_PGRP, PRIO_USER, LOCK_SH, LOCK_EX, LOCK_UN, LOCK_NB]: New variables. (scm_crypt, scm_chroot, scm_getlogin, scm_cuserid), (scm_getpriority, scm_setpriority, scm_getpass, scm_flock), (scm_sethostname, scm_gethostname): New procedures. 2001-03-08 Neil Jerram * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is not optional (ii) "recommend" spelling correction. 2001-03-08 Mikael Djurfeldt * ramap.c (racp): Removed optimization which caused array copying to fail if the two arrays shared storage. Re-inserted the IVDEP macros removed in the change of 2000-03-09. (Don't really have a complete grasp of what they are for, but they seem to be necessary on Crays. This needs testing!) Thanks to Miroslav Silovic. * hash.c (scm_string_hash): Don't downcase characters. 2001-03-07 Mikael Djurfeldt * symbols.c (scm_symbols_prehistory): Changed symbol hash table size from 277 --> 1009. * symbols.c, symbols.h (scm_sys_symbols): New function GUILE_DEBUG function. * coop-threads.c: Fixed change of 2001-03-06. * validate.h: Code formatting. 2001-03-07 Keisuke Nishida * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in. (*.doc): Add dependency on guile-snarf.awk.in. * guile-snarf.awk.in: Neglect spaces at the end of SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the middle of docstrings. (To avoid the problem with gcc-2.96.) 2001-03-06 Dirk Herrmann * coop-threads.c (scm_call_with_new_thread), load.c (scm_primitive_load, scm_sys_search_load_path), random.c (scm_c_default_rstate), struct.c (scm_make_struct_layout, scm_struct_ref, scm_struct_set_x): Don't use SCM_ASSERT to (potentially) issue a scm-misc-error or wrong-num-args error message. * load.c (scm_search_path): Use SCM_ASSERT_TYPE to give details about the expected type with the wrong-type-arg error message. * smob.c (scm_make_smob): Abort on misuse of smob - it indicates a C level bug that can't be fixed from scheme anyway. 2001-03-05 Mikael Djurfeldt * eval.c (scm_m_letstar): Removed check for duplicate bindings. Duplicate bindings are OK in a let* since a let* is semantically equivalent to a nested set of let:s. 2001-03-05 Martin Grabmueller * print.c (scm_print_options): Fixed texinfo in docstring. * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if the underlying functions getservent, getprotoent or getnetent return NULL instead of signalling an error. 2001-03-04 Gary Houston * socket.c (scm_fill_sockaddr): don't allow buffer overflows when taking an unexpectedly large filename for an AF_UNIX socket from bind/connect/sendto (thanks to Martin Grabmueller). * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the former and adjusted the latter. (scm_socket, scm_socketpair): cosmetic changes. (scm_getsockopt, scm_setsockopt): declare optlen as int, not size_t as socklen_t substitute. don't restrict args/return values to INUM: allow full range of int or size_t. (scm_fill_sockaddr): check arguments before allocating memory, to avoid leakage. use malloc, not scm_must_malloc. (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t substitute. free the sockaddr structure before throwing an error. (scm_init_add_buffer): procedure removed, together with its static buffer scm_addr_buffer, which wouldn't be thread safe. instead, define a macro MAX_ADDR_SIZE and declare the buffer where needed. (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom, scm_sendto): use a local buffer instead of scm_addr_buffer. adjust for new SCM_SOCK_FD_TO_PORT. use int for address size, not size_t. (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom call to detect whether recvfrom could be bothered to set the address. (scm_init_socket): don't call scm_init_addr_buffer. 2001-03-04 Dirk Herrmann * debug.c (scm_procedure_source, scm_procedure_environment), print.c (scm_get_print_state), ramap.c (scm_array_fill_int, scm_array_index_map_x), sort.c (scm_sort_x, scm_sort, scm_stable_sort_x, scm_stable_sort), stacks.c (scm_make_stack, scm_last_stack_frame), symbols.c (scm_sym2vcell, scm_sym2ovcell), unif.c (scm_list_to_uniform_array, scm_uniform_vector_length, scm_transpose_array, scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x, scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star, scm_array_to_list, scm_array_prototype), validate.h (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call scm_misc_error or scm_wrong_type_arg instead. * validate.h (SCM_WTA, RETURN_SCM_WTA): Deprecated. 2001-03-04 Mikael Djurfeldt * goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed. (scm_sys_tag_body): Added. 2001-03-04 Dirk Herrmann * continuations.c (continuation_apply), eval.c (scm_m_lambda, scm_m_letstar, scm_m_letrec1, scm_m_let, SCM_APPLY), eval.h (SCM_EVALIM2), evalext.c (scm_m_generalized_set_x), gc.c (get_bvec, MARK), goops.c (scm_primitive_generic_generic), options.c (scm_options), ports.c (scm_remove_from_port_table), ramap.c (scm_ramapc), read.c (skip_scsh_block_comment, scm_lreadr, scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal, script_get_backslash, script_read_arg), unif.c (scm_cvref): Don't call function scm_wta, call scm_misc_error or scm_wrong_type_arg instead. 2001-03-04 Mikael Djurfeldt * goops.c (scm_sys_pre_expand_closure_x): New procedure. 2001-03-04 Marius Vollmer * eval.c (scm_s_duplicate_bindings): New error message. (scm_m_letrec1, scm_m_letstar): Check for duplicate bindings. 2001-03-03 Marius Vollmer * eval.h (SCM_EVALIM2): New macro. Use it when a immediate, literal constant should be evaluated. * eval.c (scm_s_duplicate_formals): New error message string. (scm_c_improper_memq): New function. (scm_m_lambda): Check for duplicate arguments. (scm_ceval, scm_deval): When executing a body: only cons a new toplevel environment frame when it is different from the existing one; use EVALCAR instead of SIDEVAL so that we can properly check for empty combinations; use SCM_EVALIM2 for the same reason in the non-toplevel loop. (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin): New labels with the meaning of their non-"nontoplevel" partners, but they are used when it is known that the body is not evaluated at top-level. (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error reporting for empty combinations. 2001-03-02 Keisuke Nishida * Remove dump facilities. * dump.c, dump.h: Removed. * Makefile.am: Remove dump.c, dump.h, dump.x, dump.doc. * init.c: Remove #include "libguile/dump.h".

(Obviously nobody compiles with SCM_RECKLESS defined...) * validate.h (SCM_ASSERT_RANGE): Use the argument number. 2001-02-23 Mikael Djurfeldt * ports.c, ports.h (scm_c_read, scm_c_write): New functions. * ports.h (SCM_READ_BUFFER_EMPTY_P): New macro. 2001-02-24 Neil Jerram * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2, scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y', since use of `z' suggests that the arguments may be complex. * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring typos. 2001-02-23 Neil Jerram * dump.c (scm_binary_write, scm_binary_read), eval.c (scm_primitive_eval), guardians.c (scm_guardian_destroyed_p, scm_guardian_greedy_p, scm_make_guardian), fports.c (scm_file_port_p): Minor docstring fixes. 2001-02-22 Marius Vollmer * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x. * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of scm_i_eval. (make_class_from_template): Do not bother to set the current module around the call to DEFVAR, scm_eval takes care of that. (scm_init_goops): Make scm_module_goops and scm_goops_lookup_closure permanent objects. * eval.c (scm_ceval, scm_deval): When evaluating expressions on top level, create a fresh top-level environment for each expression instead of mutating the exisint frame. This is important when that frame is closed over. * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use SCM_DIGSPERLONG instead of DIGSPERLONG. 2001-02-21 Marius Vollmer * eval.c (scm_ceval, scm_deval): Check for wrong number of args before applying arrow procedure in `cond' and before applying receiver procedure in call-with-current-continuation. (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL macro. The argument is expanded more than one time. * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson! 2001-02-20 Marius Vollmer * guile-doc-snarf.in, guile-func-name-check.in: Added copyright notice and license. 2001-02-17 Martin Grabmueller * variable.c (scm_make_variable, scm_make_undefined_variable) (scm_variable_ref, scm_variable_set_x, scm_builtin_variable) (scm_variable_bound_p), values.c (scm_values) (scm_call_with_values), unif.c (scm_bit_count) (scm_bit_set_star_x), symbols.c (scm_gentemp) (scm_gensym), strings.c (scm_string_p, scm_make_string) (scm_read_only_string_p, scm_string_length, scm_string_ref) (scm_string_set_x, scm_substring, scm_string_append), stime.c (scm_strptime, scm_mktime), random.c (scm_seed_to_random_state) (scm_copy_random_state, scm_random), print.c (scm_newline) (scm_write_char, scm_simple_format), debug-malloc.c (scm_malloc_stats), environments.c (scm_environment_p) (scm_environment_bound_p, scm_environment_ref) (scm_environment_fold, scm_environment_define) (scm_environment_undefine, scm_environment_set_x) (scm_environment_cell, scm_environment_observe) (scm_environment_observe_weak, scm_environment_unobserve) (scm_make_eval_environment, scm_eval_environment_p) (scm_eval_environment_set_local_x, scm_eval_environment_local) (scm_eval_environment_imported) (scm_eval_environment_set_imported_x, scm_make_import_environment) (scm_import_environment_p, scm_import_environment_imports) (scm_import_environment_set_imports_x, scm_make_export_environment) (scm_export_environment_p, scm_export_environment_private) (scm_export_environment_set_private_x) (scm_export_environment_signature) (scm_export_environment_set_signature_x, scm_leaf_environment_p): Added texinfo markup. * ports.c (scm_drain_input): Lowercased argument to @var.

(Thanks to Matthias Koeppe) 2001-02-15 Marius Vollmer * symbols.c (scm_mem2symbol): Put a empty statement after the next_symbol label. This is mandated by ANSI, appearantly. 2001-02-13 Marius Vollmer * gc_os_dep.c: Do not include . It makes no sense to compile for a specific kernel version. Do not include while defining __KERNEL__. This hack should no longer be needed and caused problems. 2001-02-13 Marius Vollmer * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of SCM_CEVAL when evaluating subforms of `begin' forms. SCM_CEVAL can not deal with immediates. 2001-02-12 Keisuke Nishida * list.c (scm_list_copy): Validate the first argument. 2001-02-11 Marius Vollmer Fix evaluator so that top-level expressions are correctly evaluated with respect to the module system. * modules.h. modules.c (scm_current_module_lookup_closure): New function. * eval.h (scm_primitive_eval, scm_primitive_eval_x): New prototypes. (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument names to better reflect their meaning. * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being evaluated at top-level and synronize lookup closure before executing every subform. (scm_primitve_eval_x, scm_primitive_eval): New functions.

Provided by Martin Grabmueller. Thanks! 2001-02-10 Keisuke Nishida * dump.c (scm_store_bytes): Store data size before data. (scm_restore_bytes): Restore data size. Takes a pointer to size. * dump.h (scm_restore_bytes): Updated. 2001-02-09 Keisuke Nishida * dump.c: Use double cells for update schedule. 2001-02-08 Keisuke Nishida * ports.c (scm_unread_char): Take an optional argument. 2001-02-08 Marius Vollmer * modules.h (scm_selected_module, scm_current_module): Renamed scm_selected_module to scm_current_module to synchronize Scheme and C names. (scm_select_module, scm_set_current_module): Likewise. Changed all uses. * ports.c (scm_port_for_each): Make a snapshot of the port table before iterating over it. The table might change while the user code is running. With the snapshot, the user can depend on the fact that each port that existed at the start of the iteration is encountered exactly once. (ice-9 popen) depends on this. 2001-02-08 Dirk Herrmann * strings.h (SCM_STRING_MAX_LENGTH): New macro. * strings.c (scm_makstr, scm_take_str, scm_make_string): Added range checking for the size parameter. Thanks to Martin Grabmueller for the hint. (scm_makstr): Reordered string initialization to make interrupt deferring unnecessary. * vectors.c (scm_make_vector): Fixed range checking. 2001-02-08 Dirk Herrmann * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro. * vectors.c (scm_make_vector, scm_c_make_vector): Improved the checking of the size parameter for type correctness and valid range. Thanks to Rob Browning for reporting the problem. Instead of deferring interrupts, scm_remember_upto_here_1 is used. 2001-02-05 Keisuke Nishida * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed. (scm_dump_cell_update): Removed. (scm_dump_update): Renamed from scm_dump_object_update. (scm_restore_string, scm_restore_bytes, scm_restore_word): Takes a pointer instead of returning a value. * keywords.c (keyword_undump): Updated. 2001-02-05 Keisuke Nishida * dump.c, dump.h: Modified a lot.
