#10 | 5531 | Richard Geiger |
A significant checkpoint commit, with new improved handling of import vendor branches, and revisions present in main by virtue of multiple vendor drops to a file with no local mods. test/runtest works, with new refernece results pretty well scrutinized. |
||
#9 | 5442 | Richard Geiger |
A checkpoint commit on the way to a 2.6.0 release with the new IronPort inspired improvements. |
||
#8 | 5430 | Richard Geiger |
This is another "checkpoint" commit. It significantly rearranges how labels are done, so as to use a hueristic to divine label<->branch identifications. Not intended for release without further testing and tweakage! |
||
#7 | 3708 | Richard Geiger | Changes for 2.3.6 | ||
#6 | 2061 | Richard Geiger |
changes for 2.3.2: - can adjust db hash bucket size; - Add $DEPOT config variable - Handle labels with '#' or '@' |
||
#5 | 1987 | Richard Geiger | Changes for 2.3.1 | ||
#4 | 416 | Richard Geiger | Pull in Thomas Quinot <quinot@inf.enst.fr>'s UTC bugfix, for 1.2.12. | ||
#3 | 249 | Richard Geiger |
Changes in preparation for supporting spaces in filenames. (In fact, this may work as of this change, but is not yet tested.) Also, add "runtest -gengood" to allow easier generatino of new *.good files. (It just doesn't quick on a miscompare!). |
||
#2 | 240 | Richard Geiger |
Version 1.2.5, to account for post-1999 RCS behavior. (Courtesy of David Simon, Goldman Sachs) |
||
#1 | 130 | Richard Geiger |
CVS-to-Perforce converter. This is release 1.2.2 (first submit to the Perforce Public Depot) |
