Geiger's most recent cvs2p4 checkins.

records.

Primary
#2 5697 marc_tooley cvs2p4: Making various errors non-fatal to allow conversion to succeed
(however problematically) under harsh, corrupt source conditions.
#1 5694 marc_tooley Branching for minor little mods to cvs2p4.

It turns out the Public Depot is probably a convenient delivery
mechanism..

#47 5646 Richard Geiger Make sure we have the leading directories if both
       $CVS_ROOT and $CVS_MODULE are defined.
#46 5623 Richard Geiger $SPEC_DEPOT feature added.
#45 5615 Richard Geiger more depot mapping fixes.
#44 5611 Richard Geiger Fix a broken Depotmap{}.
#43 5610 Richard Geiger This just tightens up some pattern matches for Perforce depot-syntax
names. Should be no function change, but it's probably safer this way.
#42 5597 Richard Geiger Add news USE_IMPORT_DEPOT switch, to allow you to
have cvs-import'ed revisions (the "vendor branch") end up
in a different depot than locally-authored revisions.

This should pretty much complete feature work in 3.0;
#41 5583 Richard Geiger Handle "..." in CVS pathnames by changing them to ",,,"s.
"Works for me!"
#40 5582 Richard Geiger Fixes a problem that prevented the NOKEYEXP_PATHNAME list
from working.
#39 5571 Richard Geiger Fix the "NOKEYEXP_PATHNAME" mechanism...
so that it works :-)
#38 5569 Richard Geiger Just a variable name change:
NOEXC_PATHNAME in config is now NOKEYEXP_PATHNAME.
#37 5555 Richard Geiger NOEXC_PATHNAME
#36 5542 Richard Geiger checkpointing progress.
#35 5541 Richard Geiger fix a bug where the equivalance of 1.1 and 1.1.1.1 is not recognized.
#34 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.
#33 5510 Richard Geiger Add the $Depotmap{"somecvstopdir"} = "//somep4depot"; facility
#32 5509 Richard Geiger checkpoint
#31 5490 Richard Geiger $Depotmap implemented.
#30 5442 Richard Geiger A checkpoint commit on the way to a 2.6.0 release with the
new IronPort inspired improvements.
#29 5437 Richard Geiger just another checkpoint. Passed test/runtest, but
still has debugging cruft in. Not fit for release!
#28 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!
#27 4914 Richard Geiger Adds PureRCS switch.
#26 4885 Richard Geiger Allow using a name other than "main" for the TRUNKLINE branch.
#25 4732 Richard Geiger Changes to support special characters # @ % * (for release 2.5)
#24 4276 Richard Geiger fix dochanges so that <test_conv_dir>/depotmap is run correctly.
#23 3708 Richard Geiger Changes for 2.3.6
#22 3594 Richard Geiger Changes for 2.3.5
#21 2061 Richard Geiger changes for 2.3.2:
  - can adjust db hash bucket size;
  - Add $DEPOT config variable
  - Handle labels with '#' or '@'
#20 1987 Richard Geiger Changes for 2.3.1
#19 1977 Richard Geiger Explicit p4d -r
#18 1967 Richard Geiger Add new config item "DEADSTATE".
#17 1965 Richard Geiger Fix bug where link was being made if $COPY succeedes.
#16 1964 Richard Geiger Add $TEXTTYPE and surrounding accoutrements.
#15 1781 Richard Geiger This change reintegrates cvs2p4 2.0 developement work (through
2.0b6) back into my mainline development.
#14 1637 Richard Geiger Was removing "Revmap.db" not "$Revmap.db".
#13 1407 Richard Geiger === Release 1.3.2

- Reduce the memory footprint of bin/genmetadata. Previously, it was
  holding and sorting a complete copy of the metadata file "in-core"
  (as well as a copy of all of the RCS revision tags data!). This adds
  up quick, and some users saw genmetadata gobbling memory voraciously
  (and in some cases being running out, causing thrashing and/or process
  termination by the OS).

  genmetadata now keeps the metadata in a temp file, (sorting it in
  primary-key-sized chunks), and the revision tag information in a
  db-backed hash.

- Fix the label handling so that _all_ perforce revisions based on the
  labeled cvs revision are included in the generated
  labels. Previously, one of the N "correct" Perforce revisions were
  being tagged (effectively, at random). This stems from the fact that
  lazy copying and branching are explicit in Perforce, but implicit in
  CVS. I.e., the "#1" revision in a new Perforce branch _appears_ to
  be a separate entity (identical to the revision from which it was
  branched. This means that to use the converted labels, it will be up
  to _you_ to remember what labels go with what branches: but that's
  the way it is in CVS, too.

- A minor change in revmap to have a meaningful usage message, and
  properly handle the new rrevmap format.

- dochanges correctly deletes revmap database files for either
  *.db or *.pag/*.dat style databases.
#12 1185 Richard Geiger Changes for 1.3
(Labels!)
#11 1172 Richard Geiger Complete the toleracne of change renumbering.
#10 1150 Richard Geiger Allow messages about change renumbering, so cvs2p4 can be used
to import to an existing (nonvirginal!) server. Note that I
*don't* claim this works completely now, but from my
experience at Orca a year ago, this was the only bugaboo that
bit. Note also that it's still the user's obligation to insure
that there are no pathname overlaps with files that already
exist. *That* is guarenteed
       not to work!
#9 791 Richard Geiger Update for a new release; my change-of-venue noted;
desensitized to conflicting P4CONFIG.
#8 421 Richard Geiger Fix to the fix by Thomas Quinot.
#7 416 Richard Geiger Pull in Thomas Quinot <quinot@inf.enst.fr>'s UTC bugfix, for 1.2.12.
#6 250 Richard Geiger Changes to allow coping with shell metacharacters (' ' & '$', at least)
in file names.
#5 249 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!).
#4 240 Richard Geiger Version 1.2.5, to account for post-1999 RCS behavior.

#3 228 Richard Geiger Changes for 1.2.4 - recognize alternative "p4 files" message
for files not present in the depot.
#2 179 Richard Geiger CHanges for 1.2.3
#1 130 Richard Geiger CVS-to-Perforce converter.
This is release 1.2.2
