.ifi init_plm "SIB12.2" .srv section "C" .srv draft_date "" .srv draft "Changes to IMFT" .ifi l0h "Significant Changes to IMFT" This release contains a new version (4.0) of the IMFT facility. System administrators should note the following: .spf 2 .inl 5 .unl 5 1) The "version" keyword in the attach description for an IMFT driver will no longer accept "old" or "new". The only values that will be accepted are "2.0", "3.0" or "4.0". .spf The 4.0 version of the IMFT facility is able to converse with drivers on other systems using previous versions. The version keyword identifies to the local driver what version the driver at the other end is using. .spb 2 .unl 5 2) The following changes have been made to the enter_imft_request (eir) command: .spf New control arguments have been added to the enter_imft_request (eir) command and include: .spf .unl 3 -date_time_after DT, -dtaf DT .brf skips selected files and subtrees if their date_time_contents_modified value is older than the time selected by DT. This option is not applied to contents of subtrees. The DT string must be acceptable to the convert_date_to_binary_ subroutine. This option facilitates selecting only modified information to reduce IMFT traffic. .spf .unl 3 -skipped, -skpd .brf turns on the display of the objects that are skipped when the -date_time_after option is used. .spf .unl 3 -no_skipped, -nskpd .brf turns off the display of the items that are skipped when the date_time_after option is used. (Default) .brp .unl 3 -delete, -dl .brf deletes source IMMEDIATELY after it is successfully transferred. .spf .unl 3 -no_delete, -ndl .brf does not delete objects. (Default) .spf .unl 3 -extend .brf appends the contents of the source to the contents' end of the target path. An error occurs if the source path is a nonfile. An error occurs if the target does not already exist. It is incompatible with the -subtree option. .spf .unl 3 -replace .brf replaces the entire file target path, rather than modifying its contents as is done by -extend and -update. (Default) .spf .unl 3 -update, -ud .brf replaces the contents of the target path with those of the source without deleting the target path or changing any of its attributes. An error occurs if the source path is a nonfile. An error occurs if the target path does not already exist. It is incompatible with the -subtree option. .spf 2 .unl 5 3) Access checking has been expanded to require that proper explicit ACL entries must exist for both the IMFT driver daemon and the user for all objects being transferred. This new version will check all objects in the subtree for proper ACL when a directory is specified in the IMFT request. An explicit ACL entry is one which includes both the person name and the project name; ie, "Smith.*.*", "*.Project.*" or "*.*.*" is no longer acceptable. Each object to be transferred must have an appropriate "Person.Project.*" ACL entry for both the IMFT driver and user. .spf This expanded ACL checking also includes that which is done with the SITE.imft.acs segment. Only the ACL for the user is required but it must have a Person.Project.* entry with the appropriate "r" or "rw" access. .spf See book.imft.compout in the >doc>MR12.2 directory on the release tapes for more details. .inl 0 ----------------------------------------------------------- Historical Background This edition of the Multics software materials and documentation is provided and donated to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc. as a contribution to computer science knowledge. This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology, Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL and BULL HN Information Systems Inc. to the development of this operating system. Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970), renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for managing computer hardware properly and for executing programs. Many subsequent operating systems incorporated Multics principles. Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
