#81 | 6301 | Richard Geiger |
These changes resulted from a recent customer conversion. A checkpoint, more or less. |
||
#80 | 5888 | Richard Geiger |
This fixes a subtle and heinous bug whereby imports done before a file gets a local change on "main" will be lost (even though the local change will reflect the contents of those "lost" revisions) cc: releng@ironport.com, ehuss@ironport.com |
||
#79 | 5811 | Richard Geiger |
I believe this changes handles the problem encountered by Henry Grishashvili at IC Manage. |
||
#78 | 5673 | Richard Geiger | checkpoint ironport latest. | ||
#77 | 5667 | Richard Geiger | fix a/na dup detection. | ||
#76 | 5656 | Richard Geiger | Another fix for cases where TRUNKLINE is not head. | ||
#75 | 5654 | Richard Geiger | Take care of David Birkhead's first two problem children :-) | ||
#74 | 5651 | Richard Geiger | Cosmetic only | ||
#73 | 5647 | Richard Geiger |
fixes for case of trunkline set to a branch (! the trunk) where a file is initially added. |
||
#72 | 5633 | Richard Geiger |
Handle the "filename" attribute that some RCS/CVSes apparently create these days... Also, be sure to wipe the Convdir/p4root before genmetadata does it's thing, so as to remove any ,v files that genmetadata might find there. Also for general hygiene! |
||
#71 | 5615 | Richard Geiger | more depot mapping fixes. | ||
#70 | 5588 | Richard Geiger |
checkpoint the latest. This includes a rework of the label-heursitical stuff that seems to work better. |
||
#69 | 5587 | Richard Geiger | Handle \r's in filenames by xlating to "%0d". | ||
#68 | 5585 | Richard Geiger |
do complete branch determination in bin/genmetadata now... heh. |
||
#67 | 5583 | Richard Geiger |
Handle "..." in CVS pathnames by changing them to ",,,"s. "Works for me!" |
||
#66 | 5581 | Richard Geiger | pull out unintended leftover debug cruft. | ||
#65 | 5580 | Richard Geiger | Tweaks & debugging fixes from the IP 2006/07/06 trial. | ||
#64 | 5570 | Richard Geiger | decruftification. | ||
#63 | 5568 | Richard Geiger |
If we are doing BRANCH_FLASH, do it consistently BEFORE using the un-de-flashed (!) value anywhere else! |
||
#62 | 5567 | Richard Geiger |
Seems pretty close to right at this point. This change makes sure that we handle labels on "ambiguous" revisions (any 1.1.1.n, n > 1 revisions commited before any 1.2) as being present in *both* the import branch AND main correctly. |
||
#61 | 5563 | Richard Geiger |
Life is a corner case. "UNMAPPED-COLLISION tags in tags.txt now indicate what collided better. Fix srcdiff to handle odd Log expansion corner case that was causing flase positives. |
||
#60 | 5555 | Richard Geiger | NOEXC_PATHNAME | ||
#59 | 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. |
||
#58 | 5500 | Richard Geiger |
Fix handling of special chars in filenames with new rlog-based parsing. |
||
#57 | 5498 | Richard Geiger | Eeeks, where did this line go!? | ||
#56 | 5497 | Richard Geiger | checkpoint | ||
#55 | 5495 | Richard Geiger |
Slight change to parsing rlog output, for better tolerance of people pasting rlog output into log messages. This also depend on the new rlog... |
||
#54 | 5494 | Richard Geiger |
Heck, it's turning into 3.0! This is a watershed commit - switch to rlog-based ,v parsing... |
||
#53 | 5490 | Richard Geiger | $Depotmap implemented. | ||
#52 | 5489 | Richard Geiger | New checkpoint; now has multi-mod exclude_* files. | ||
#51 | 5485 | Richard Geiger | good checkpoint | ||
#50 | 5484 | Richard Geiger | checkpoint | ||
#49 | 5483 | Richard Geiger |
The latest formula... ...and a typo. |
||
#48 | 5480 | Richard Geiger |
Better vendor-branch handling... it's tricky! genmetadata now includes a flag in each line of the generated $Convdir/labels to indicate whether the file in question had "$Rcs_import_is_main" set. (The file had "branch: 1.1.1" as the default branch). |
||
#47 | 5477 | Richard Geiger | Fix bug in prescan mode. | ||
#46 | 5476 | Richard Geiger | I am import, hear me roar. | ||
#45 | 5466 | Richard Geiger |
allow leading whitespace and/or trailing # comments in exclude_* lists. |
||
#44 | 5465 | Richard Geiger | Add exclude list for tags & branches. | ||
#43 | 5442 | Richard Geiger |
A checkpoint commit on the way to a 2.6.0 release with the new IronPort inspired improvements. |
||
#42 | 5437 | Richard Geiger |
just another checkpoint. Passed test/runtest, but still has debugging cruft in. Not fit for release! |
||
#41 | 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! |
||
#40 | 5428 | Richard Geiger |
A checkpoint commit; this adds a first stab attempt at a global (across all files) hueristic for determining the tag<->branchtag mapping. It seem to be working, but has not been deeply tested yet at all. There is also debugging cruft that should be removed before this goes into a release. Also, ALL of the big (per-file or more) hashes now get stored as tie'ed databases, in order to deal with memory exhaustion when dealing with BIG data sets. |
||
#39 | 5426 | Richard Geiger | Add compilation of the tags and branch tags encountered. | ||
#38 | 5392 | Richard Geiger | Adjust sort key specifier option to avoid the archiaic form. | ||
#37 | 5272 | Richard Geiger | Allow "."s in author identifiers | ||
#36 | 5199 | Richard Geiger | hush $CO .adamci | ||
#35 | 5198 | Richard Geiger | First cut "ADAM" support for Intel Austin. | ||
#34 | 5143 | Richard Geiger | prep for 2.5.5 | ||
#33 | 5091 | Richard Geiger |
Fix delta processing - some labels (with nonnumerics following numerics) could otherwise confuse the parsing. |
||
#32 | 4917 | Richard Geiger |
in PureRCS, always use the RCS branch number in the depot path. even for the #1 revs (which really point to it in RCS). |
||
#31 | 4914 | Richard Geiger | Adds PureRCS switch. | ||
#30 | 4732 | Richard Geiger | Changes to support special characters # @ % * (for release 2.5) | ||
#29 | 4296 | Richard Geiger |
Integrate Robert Cowham's fox for the "binary slows"... In Cowham we Trust! |
||
#28 | 4270 | Richard Geiger | Handle symbols name starting with a leading "num". | ||
#27 | 3708 | Richard Geiger | Changes for 2.3.6 | ||
#26 | 2376 | Richard Geiger | First show at fixing RCS/"import" confusion... | ||
#25 | 2284 | Richard Geiger |
Package 2.3.3. Changes to begin handling MKS Source Integrity repositories. Today MKS; Tomorrow... ClearCase! (well). |
||
#24 | 2239 | Richard Geiger |
Ignore "ext" and "format" RCS keywords. These are apparently added by MKS's rendition of RCS. Ug. |
||
#23 | 2061 | Richard Geiger |
changes for 2.3.2: - can adjust db hash bucket size; - Add $DEPOT config variable - Handle labels with '#' or '@' |
||
#22 | 1987 | Richard Geiger | Changes for 2.3.1 | ||
#21 | 1942 | Richard Geiger |
Change to handle RCS branch tags (so this tools can work with RCS (vs CVS) repositories, too!) RCS branch tags are those with an even number of "."s. |
||
#20 | 1781 | Richard Geiger |
This change reintegrates cvs2p4 2.0 developement work (through 2.0b6) back into my mainline development. |
||
#19 | 1437 | Richard Geiger | Fix for 1.3.3 - labels on revived Attic files. | ||
#18 | 1404 | Richard Geiger |
Oops, fix a bug ni the sort re-do from the last change: the external sort needs a -n. You'd think it would be smart enought to know what I want. Sheesh. :-) |
||
#17 | 1388 | Richard Geiger | Put genmetadata on a memory diet. | ||
#16 | 1203 | Richard Geiger |
Fix bug where dolables couldn't cope with tag in which the revision for a file was a delete Add the IMPORTTAGSPOOF switch. |
||
#15 | 1185 | Richard Geiger |
Changes for 1.3 (Labels!) |
||
#14 | 1031 | Richard Geiger | Changes for 1.2.17; fix one-letter id internal error bug. | ||
#13 | 823 | Richard Geiger | Add assert for dup d/f,v d/Attic/f,v (like "Giao Phan" <giao@seven.com> saw) | ||
#12 | 474 | Richard Geiger | Reject files with bad characters per perforce filenaming conventions. | ||
#11 | 459 | Richard Geiger |
Now performs metadata sort using a sort routine coded directly in perl, rather than by using the host system's "sort" command. (Differences in "sort" behavior from one host to another had been observed to cause irregularities). |
||
#10 | 416 | Richard Geiger | Pull in Thomas Quinot <quinot@inf.enst.fr>'s UTC bugfix, for 1.2.12. | ||
#9 | 398 | Richard Geiger | Skip (and note) ,v files with nonprintable characters in the fileame. | ||
#8 | 392 | Richard Geiger | CHanges for 1.2.10 (tolerate empty RCS file) | ||
#7 | 342 | Richard Geiger | Allow for "." in "id" symbols. | ||
#6 | 330 | Richard Geiger |
This change allows cvs2p4 to cope with RCS archives with CR/LF line endings. (I'm not sure how these get created; presumably some weird side effect of Bill Gates. But one user had 'em; RCS seems to cope with 'em, and so I've decided to make cvs2p4 follow suit. |
||
#5 | 305 | Richard Geiger | Changes for 1.2.7 | ||
#4 | 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!). |
||
#3 | 240 | Richard Geiger |
Version 1.2.5, to account for post-1999 RCS behavior. (Courtesy of David Simon, Goldman Sachs) |
||
#2 | 179 | Richard Geiger | CHanges for 1.2.3 | ||
#1 | 130 | Richard Geiger |
CVS-to-Perforce converter. This is release 1.2.2 (first submit to the Perforce Public Depot) |
