NEWS #1

=== Release 3.0b6, Spetember 5, 2006

- Fix a bug which was tickled by revisions initially added on a CVS
  branch, where the branch is selected as TRUNKLINE (i.e., to become
  the logical "main" in Perforce. Thanks to David Birkhead
  (<daveb@data-pipes.com>) for  reporting this bug. The symptom
  was missing revisions in the converted result.

- Fix a problem that occured when both CVS_ROOT and and CVS_MODULE
  were defined in the configuration file.

- The rcsfixup script now handles rcs files with "mergepoint:"
  and "filename:" attributes in RCS files. (Some newer RCS/CVSes
  create them).

- Add the $SPEC_DEPOT config variable, to specify that a "spec depot"
  be created in the Perforce result.


=== Release 3.0b5

- Yet another labels-related bugfix.

- Add the $SPEC_DEPOT config option, which, if set, gives a name, with
  with a spec depot will be created in the conversion result.

- bin/srcdiff now handles paths with '$'s in them correctly. Hey \r's, too!


=== Release 3.0b4, August 1, 2006

- Fixes a bug in converting labels; files originally imported
  with "cvs import" and unchanged since the import would be omitted
  from a converted label (in which they should be present).


=== Release 3.0b3, July 28, 2006

- Further fixes to depot mapping wrt labels.

- The correct set of depot specs are now created

- the imported cvs repository is now kept in a special depot of it's
  own - "//cvs2p4/" - by default.


=== Release 3.0b2, July 26, 2006

- Fixes a bug in the $Depotmap{} feature.


=== Release 3.0b1, July 24, 2006

This release represents a major rework, driven by the needs of the
most ambitious conversion I have ever performed. The demands of this
conversion have required that the tools both perform better, and
support additional new features, especially with respect to
heuristically determining correct CVS release tags to Perforce
branches.

At least one external "alpha" test user has performed a conversion
using this code. I've decided to call this a "beta" release simply to
alert users that there may be some rough edges. However, given the
degree of testing it has undergone, I would encourage potential users
to use this release rather the final one of the 2.n series.

Here's a laundry list of the changes since 2.5.5. I have decided to
leave the list in time order (versus by significance of the change)
for now, at least. But one change in particular bears special mention:

  ** This version now requires a specially patched version of the
  ** "rlog" command (from RCS) in order to work. The required patch is
  ** supplied in the release; you will need to apply the patch, and
  ** compile a new version of rlog. See the section
  ** "src/rcs-5.7/src/rlog.c.patch" in the README file for further
  ** information.

Changes since 2.5.5:

- Tweak the test/runtest script to sleep for 2 seconds after issuing
  the "p4 admin stop" command, to give the server time to shut down.
  This was causing problems on some systems.

- Yowsa! Eating my own dogfood at a real conversion just now, of a
  moderately large 5-year-old CVS repository, I feel your pain, oh ye
  who have suffered... shall we say: "label bloat"?. Both the dblabels
  (journal-format) file AND the final resultant db.label file get very
  large very quickly. In part, this is because the "extra" label
  records that get written for branches consume space, I'm
  guessing. BUT the fact that we write a temp file (dblabels), and
  then replay it into the Perforce server, makes the conversion take
  up much more disk space.

  As a simple hack to provide immediate relief, I have rejiggered
  bin/dolabels such that the "dblables" data stream is written directly
  into an instance of "p4 -jr -". This saves the time and disk space
  involved writing the temp file, which is, normally, not reused
  after the conversion. Waste not, want not!

- Achh! I have encountered a repository with "."s in the author:
  names. These are supposed to be illegal (as I read rcsfile(5)).
  But cvs2p4 now tolerates them.

- bin/dolabels has been tweaked so as to allow a user-supplied
  "labelmap" file to give hints as to which labels really correspond
  to which branches.

- Up till now, bin/genmetadata has used to use the "sort +1" form of
  specifying sort keys.  This seems to be obsolescent; the sort in
  Fedora Core 3 seems to still support it, but the one in FC5 no
  longer does. I have switched to the "-k 2" form for this, and it
  seems to work fine on FC3 and FC5. [Seems OK on FreeBSD 4, too].

- bin/genmetadata now leaves two files, tags.txt and brtags.txt, in
  the conversion directory. These are, simply, sorted lists of the
  "plain" tags and branch tags encountered during the scan of the CVS
  repository. "brtags.txt" contains one line per branch tag
  encountered in the conversion. "tags.txt" is one line per tag,
  being the tag name, whitespace, and then a '\001'-separated list
  of branches in which the revision is present.

  These can be useful when you are faced with the task of
  building a mapping function between CVS tags and CVS branches, for
  use with the branch_for_tag() function in bin/dolabels.

- bin/genmetadata can now infer tag->branch mappings heuristically in
  many cases; the mappings thus determined are recorded in the
  <convdir>/tags.txt file, which bin/dolabels now knows how to load
  and use. The overall effect is that now, by default, Perforce labels
  will be created for those CVS release tags for which a branch
  mapping was discovered heuristically. (And, by default, ONLY these!)
  Please see the new "RCS/CVS Tag to Perforce Label Conversion"
  section in the README file for more details.

- $P4ROOT now defaults to being placed _inside_ the "conversion dir",
  making it easier to have multiple conversions around without
  collisions.

- I believe that cvs2p4 now runs in a fixed memory footprint; all
  large data sets are now kept in DBM databases. If you see evidence
  otherwise please let me know!

- In order to have a way of gauging bin/dolabels progress, it now
  prints out an input file line count for every 10,000 lines of the
  "labels" file as it is processed.

- In previous editions, with $COPYIMPORT=1, the copy of the CVS
  repository tree left under $P4ROOT had directory write permission
  turned off on directories in the copy. This prevented running the
  automated tests repeatedly, since the attempt to remove the existing
  $P4ROOT at the start of the second and subsequent runs would
  fail. Write permission is now left on in the newly copied
  directories.

- Change from the not-so apropos Artistic license to the lithe MIT
  license.

- Improved handling of vendor branch files, and the intricacies of
  whether vendor-dropped files have been modified locally or not.
  (See the notes labelled "VENDOR-DROP BRANCHES" and in the README
  file).

- Added $Depotmap{} feature for mapping top-level subdirs of
  CVS_MODULE into different depots.

- OK, this is what I call NEWS!: Yesterday I noticed genmetadata - the
  one I sweated to make fast with huge binaries with a few large
  revisions go fast - going real SLOW on a file with thousands of
  small text revisions. I gave up, patched rlog to have the one
  missing shred of info I needed, and reimplemented the whole thing to
  just use rlog. Call this bullet bitten!

  I've verified that this version produces IDENTICAL results to
  to older perl-based parsing... in about half the aggregate time.

- There is now a facility allowing you to map top-level directories in
  the CVS content being converted into multiple different Perforce
  depots.  Basically, just add a line in the following format to the
  config file for each such mapping you want to establish:

    $Depotmap{"<topdir>"} = "<depot>";

  All files with no such mapping in effect will be put into the
  default depot path defined by $DEPOT in the config file.

- No question, this gets to be 3.0! :-). It now does special spoofing
  treatment for cvs import-ed files, to match the cvs behavior when
  multiple vendor drops have been taken, with no local modifications
  yet applied. Label generation has been fixed for these so that
  labels applied to, e.g., 1.1.1.2 revisions before any 1.2 is checked in
  will appear to be in *both* the "import" branch and the "main" branch,
  just the way they behave in CVS. This required very significant mucking
  in all stages of the pipeline! Much testing will ensue...

- bin/srcdiff copes with relative paths now, like a reasonable person
  might assume it would.

- The "vendor branch" names found in the RCS archives of files created
  by "cvs import" (i.e., the names of thags on "1.1.1"), are used as
  the vendor branch name, rather than "import". (The old behavior, of
  flattening them out into a single "import" branch, may be added back
  as an option in the future if it's missed at all)

- There is now a special list you can use to declare files which
  should explicitly be treated as binaries. Please see the
  "BIN_PATHNAME" section at the end of the config file.

- The test/config file has been split-cloned into

    test/config.test
    config.tmpl

   The former has the required defaults for running the test,
   while the latter can provide a good place for users to start.

- Added the $USE_IMPORT_DEPOT config option; if enabled (by assigning
  a depot name to it), revisions from the 1.1.1 branch (aka the cvs
  import "vendor" branch) will be placed into the depot named by
  $USE_IMPORT_DEPOT. If used, the name must include the leading "//",
  e.g.,

    $USE_IMPORT_DEPOT = "//import";


=== Release 2.5.5, September 29, 2005

- The conversion now detects files where the default RCS branch is set
  to "1.1.1", and treats such files as if the "import" branch (1.1.1)
  were on the branch designated as "main" (usually, the trunk).

  This can be desirable for files which have been repeatedly "cvs
  imported" with multiple "vendor-drops", but no revisions have been
  checked in on the trunk after the first revision, AND you want the
  latests of the vendor drops (i.e., the head of the 1.1.1 branch)
  for the file.

  It's possible somebody might want the old behavior, but for now, I
  am going to leave the new behavior hardwired, as it may be more
  generally correct.

- A bug affecting labels on files whose pathnames contain Perforce
  special characters has been fixed.


=== Release 2.5.4, May 28, 2005

- Add bin/srcdiff, a tool for more easily comparing checked-out
  versions of a src from CVS and (posto-converto) Perforce. Helpful
  for easing worry in the minds of doubters in cvs2p4's fidelity.
  You can doubt *my* fidelity, but don't go doubting that of my tools!
  (no apostrophe).


=== Release 2.5.3, April 26, 2005

- bugfix: 2.5 added support for '#' and '%' in filenames (to match
  newer Perforce servers, which now allow these). DUe to a bug,
  however, these characters were being effectively transposed in the
  result of the conversion.


=== Release 2.5.2, April 25, 2005

- bugfix for the new $PureRCS feature... always use the RCS
  branch number for #1 revs, not the internal ...0.n number!


=== Release 2.5.1, April 25, 2005

- This adds an (experimental) switch ($PureRCS in the config file) intended
  to aid in conversions from "pure RCS" repositories. By "Pure RCS", we
  mean that the repository was not have been created using CVS, and so
  lacks CVS branch tags.

  With $PureRCS = 1, the conversion will be done using, for each file,
  the numeric RCS branch names found in RCS.

  "Change aggregation", using the standard hueristic is still performed,
  and labels are imported as usual.

  The intent is that Perforce style branching can be established
  as a post-import operating, by do integrations based on labels
  known to correspond to a logical branch.


=== Release 2.5, January 3, 2005

- The converter now handles the newly admitted (in Perforce 2004.2)
  special characters '#', '*', '%', and '@' (in client filesystem
  pathnames) properly.


=== Release 2.4, July 23, 2004

- fix dochanges so that <test_conv_dir>/depotmap is run correctly.

- Improved rcstok function in genmetadata to better cope with binary files.
  Previous version was potentially taking a *very* long time...
  [Thanks to Robert Cowham, robert@vaccaperna.co.uk for this fix!]

- Added two new template functions, "branch_for_tag()" and
  "rev_on_branch()". These allow dolabels to act much more intelligently
  about applying labels to the correct branch, only, and may result in
  a very significant savings in terms both of running time and disk space.
  For now, see the comments bin bin/dolabels (seach for "branch_for_tag")
  for an explanation of how to use this. When these function are NOT
  defined (as in the default as-shipped state), dolabels behavior will
  be the same as in previous releases.
  [Thanks to Kate Ebeneter and the iPod people for helpng to test this!]


=== Release 2.3.8, April 19, 2004

- Correctly handle symbol names that begin with a {num}.


=== Release 2.3.7

- Add the "HOW TO PACKAGE MODIFICATIONS" section to the README file.


=== Release 2.3.6, October 7, 2003

- Added "use bytes;" to all of the bin/* scripts, so that newer
  perls, which apparently do Unicode by default, won't. (I don't know
  whether any RCS's ever do Unicode, anyway.

- Also, made a tweak to the test/runtest script, purported to be
  necessary for the tests to work correctly on some Solaris systems:

    217c217
    < my $p4d_vers = `$P4D -V | grep ^Rev`;
    ---
    > my $p4d_vers = `$P4D -V | grep '^Rev'`;
    rmg $ 

  I don't know why this might be needed; some shell treating '^' as a
  metacharacter, I guess. (I seem to recall csh doing something with
  it, but isn't perl supposed to alway exec the "system's command
  shell", which, I thought was always /bin/sh on Unixes, but then,
  hey, it's Solaris, right? Anyway, it's benign.


=== Release 2.3.5, August 26, 2003

- Fixes a spurious test failure when using the "test suite",
  presumably caused by changes in the diff algorithm (hence in p4
  describe output) in Perforce 2002.2. The test will report success
  correctly for 2003.1 and earlier supported releases (see the README
  file for the current list of supported releases.

- For added safety, the $DEPOT tree of imported RCS archives is made
  read-only after being copied, so as to prevent changes to any of the
  files containing the imported revisions.


=== Release 2.3.4, November 21, 2002

This change corrects a problem introduced when cvs2p4 was given the
ability to handle RCS branch tags. Essentially, when files (like the
"datefile" test file) have RCS tags on the 1.1.1 branch, the scripts,
which fake an "import" branch tag for this same revision, can get
confused. This change forces the 1.1.1 branch to be known only as
"import", always.


=== Release 2.3.3, October 28, 2002

Changes to start coping with MKS Source Integrity conversions.

This change allows genmetadata to simply ignore (and hence, to
continue working!) the "ext" and "format" keywords that MKS Source
Integrity apparently adds to the rcs repertiore. This could possibly
be recoded to deal with arbitrary new keywords, but I don't want to go
there now.

Note that there *may* be other gotchas when attempting to use cvs2p4
to convert MKS SI repositories, which may be addressed by future
changes to cvs2p4:

  1. It appears that MKS may compress (gzip) binary ,v files, but *not*
     rename them to reflect this. Very odd.

  2. It appears that MKS may allow a larger character set (than pure RCS) 
     in legal symbolic names. I can probably fix cvs2p4 to deal with these
     pretty easily, but we should also consider whether any of the MKS names
     might be illegal in Perforce (and thus needs some sort of
     translation).

Intrepid users setting out to use this tool to convert MKS into
Perforce are encouraged to send problem reports to
"opensource@perforce.com".


=== Release 2.3.2, September 3, 2002

Add $DEPOT config item, allowing RCS archives to appear as
$P4ROOT/$DEPOT/$CVS_MODULE; I.e., with $DEPOT set to "depot/IMPORT",
the RCS archive files will end up under
"depot/IMPORT/<modulename>/<filepath>"; With $DEPOT set to "depot",
they will be, simply, "depot/<modulename>/<filepath>". This makes it
easier to make later merges of subsequently imported changes easier.

Changed the database open code to allow setting the size of hash
buckets (allows large conversions without running out of space for
hash table pages).

Handle label names with '#' or '@' by substituting "_hash_" and/or
"_atsym_" into the converted label name.

(Thanks to Marc Tooley of Perforce Support for supplying these
imporvements).


=== Release 2.3.1, July 30, 2002

Now always run p4d with an explicit p4d -r, in case the user's
environment has a P4ROOT set.

genmetadata now reports both the CVS file archive path and the
converted file path as it processes each file. This makes it easier to
tell what RCS archive file caused a problem if the file cannot be
parsed properly.

The scripts now use the more modern tie()/untie() database interface,
instead of the older dbmopen()/dbmclose() interface. The scripts
assume the presence of the DB_File (Berkeley DB 1.x) module. This
means that you are no longer left to the whim of the dbm support
compiled into your perl. Certain dbm implementations, notable that in
recent Solaris, caused problems. If you don't have DB_File support for
your perl, you'll need to find the tie() statements in the bin/*
scripts, and modify them to use some dbm package that you do have on
your system.

$P4_DEPOT can now be set to something that doesn't start with
"//depot/", and things will work properly (a new depot specification
will be created in the converted database).

Added README notes about conversions that merge into an existing
depot.


=== Release 2.2, July 18, 2002

You can now choose the Perforce filetype you'd like to have ALL of
your text files imported with. As long as it's "text" or "ktext" :-).
See the "$TEXTTYPE" configuration item.

For "developers": Added a new test/getgood script to grab the test
comparision files which have changed with a "runtest -gengood". Less
tedium.

Made the test/phone.gif,v a binary (-kb) RCS file, so we really test
that.

Fixed a bug in dochanges, wherupin the command to create a symlink to
the RCS archives was being created in copy mode, provided the copy did
not fail. Reported by John Wong (jw at unicom.com.au).

Added a new config item "DEADSTATE", for saying what RCS state value
means "deleted" in Perforce. It defaults correctly for CVS, so if
you're converting real CVS, you can just leave this as-it.


=== Release 2.1, July 10, 2002

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.


=== Release 2.0, May 6, 2002

No functional change since 2.0b6; This becomes the first public
release of cvs2p4 2.


=== Release 2.0b6, May 1, 2002

- handle Attic files correctly - this required a change from the old
  version (and required touching genmetadata), since we now use the
  old RCS archive tree in place (or a copy thereof).

- dolabels now closes the labels journal file explicitly. Previously,
  the subsequent "p4d -jr" could see premature eof to due buffered
  data, and the last bunch of labels in the dblbls file would not
  be converted.

- fix a bug that broke conversion of files that had been deleted and
  then re-added in CVS; upon re-adding the file, it would be given
  revision #1 agian, instead of the next unused revision number.

- added a couple of test cases for these.

Many thanks to Fan Zhang of Numeritech for helping to wring out
these problems!


=== Release 2.0b5, April 29, 2002

- handle binaries correctly. Since we're using imported RCS ,v
  files in the archive, we need to make binaries "binary +D"
  (or "xbinary +D"). Add a .gif to the tests to test this.


=== Release 2.0b4, April 29, 2002

- dochanges now writes a record for the upgrade counter counter.
  it also checks the p4d version to verify we have 2002.1 or
  better, and does a p4d -xu if later than 2002.1.


=== Release 2.0b3, April 17, 2002

- dochanges now writes a record for the change counter! (Previously,
  it was left uninitialized, so the converted server would try to
  allocate change #1 again.)


=== Release 2.0b2, April 16, 2002

- Add $CHECKBIN config option to control whether RCS revisions are
  checked out to apply the perl -B operator as part of determining
  what revisions should be treated as binary in Perforce.

- Make the list of file extentions to be treated as binary a config
  file item ($EXT).

- Add $COPYIMPORT (and command line -c) to dochanges, to request that
  the CVS tree be copied into (rather than linked to from)
  $P4ROOT/depot/IMPORT.


=== Release 2.0b1, April 15, 2002

- This release contains a major overhaul for performance. The
  "dochanges" and "dolabels" stages now directly generate
  checkpoint-format Perforce metadata, and then replay it with "p4d
  -jr" in order to create the Perforce metadata; also, the generated
  metadata causes the RCS archives in the CVS repository being
  converted to be used directly. Thus, the time-consuming "replay"
  of Perforce operations is avoided.

  "genmetadata" and "genchanges" remain unaltered in this release.

- The modification times on individual file revisions are now
  correctly preserved in the converted Perforce database (in previous
  versions, the changelist times correctly reflected the times of the
  original CVS submits, but individual file revisions times were set
  to the time of conversion).


=== Release 1.3.3, February 9, 2002

- Yet another fix for label handling, when files which had been
  moved to the Attic/ in CVS have been readded.


=== Release 1.3.2, February 5, 2002

- 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.


=== Release 1.3.1, January 4, 2002

- Make dolabels ignore errors from "- label in sync.", which happens when
  the revision of a file in the label is a delete.

- Add the $IMPORTTAGSPOOF option (see test/config comments for details)


=== Release 1.3, December 26, 2001

- Add
    Change [0-9]+ renamed change [0-9]+ and submitted.\$
  to
    $check_submits in bin/dochanges

  and recognize the /^Change \d+ renamed change (\d+) and submitted\.$/
  form of the success message.

  Allows 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 guaranteed not to
  work!

- First whack at support for creating Perforce labels from CVS tags.
  CVS *branch* tags are treated as branching information, (same as
  ever), but plain old tagged revisions get built into Perforce labels.
  The Perforce labels are created with the default (all-depot) view
  mapping.

  The mods involved changes to genmetadata (to remember the label
  info), dochanges (to make the RCS-to-Perforce revisions map (the
  existing revmap went the other way, so now we have both), and a new
  stage "dolabels" to create and populate the labels.

  Also sundry files for test cases & machinery.

  This implementation has not yet been tested a great deal with real
  road mileage, but, alas, this time I'm adding the feature for other,
  rather than as part of my own big conversion effort. So, we'll see.

- revmap output for the Perforce -> RCS direction is now cleaner.

- Finally, in putting in the support for labels, I was forced to look
  a lot closer at a lot more of the code than I have in some time.
  Needless to say, there's much I would do differently a second time
  around (and considering the tool to be more than a one-use thing to
  begin with!). Also, I'm now armed with enough knowledge, I think, to
  do a fast "direct to metadata" conversion...


=== Release 1.2.17, November 5, 2001

- Add an assertion for duplicate filenames d/f,v & d/Attic/f,v
  (This is not valid in a CVS repository!)

- Fix a bug where one-letter identifiers would cause an internal error in
  genmetadata. (Bug reported by Rich Ireland <rireland@enterasys.com>)


=== Release 1.2.16, August 27, 2001

- Reflect my recent job (and email address) change

- Changes some of the default values (and names) of "config" file
  variables, to better match the environment I'm most like to work
  in now.

- Change all "p4" invokations to explicitly specify P4PORT, P4CLIENT and P4USER
  on the command line, so as not to be confused by and P4CONFIG files that
  might otherwise come into play.


=== Release 1.2.15, December 12, 2000.

- Now rejects filenames with illegal Perforce characters.
  (Fix supplied by Doug Quist).


=== Release 1.2.14, November 20, 2000.

- 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).


=== Release 1.2.13, September 12, 2000.

- Fixes a bug (resulting in bad date translations) introduced in the
  bugfix in 1.2.12. (Fix supplied by Thomas Quinot).


=== Release 1.2.12, September 11, 2000.

- Includes a bugfix, supplied by Thomas Quinot <quinot@inf.enst.fr>,
  to correctly handle the fact that RCS timestamps in repository files
  are in UTC; this was causing the timestamps to be off (by the
  difference between UTC and the Perforce server's local time) in
  converted depots, and, in some cases, cause outright
  failures. (I.e., when the UTC time had never existed in local time,
  due to daylight savings transitions.)


=== Release 1.2.11, August 30, 2000.

- Skip (and note) ,v files with nonprintable characters in the fileame.


=== Release 1.2.10, August 24, 2000.

- Tolerate "empty" RCS ,v files that can (reportedly) be created due to
  certain failing cvs operations. (These files will be ignored;
  previously, they would cause a fatal error in genmetadata).


=== Release 1.2.9, May 16, 2000.

- Allow "." in "id" symbols in RCS files. (Author names like "ralph.spoilsport")


=== Release 1.2.8, May 11, 2000.

- Handles cr/lf line endings in RCS archives.


=== Release 1.2.7, April 5, 2000.

- A fix for a bug that caused genmetadata to croak when it
  encountered an RCS file with the default branch set, a la
  "rcs -b1 file,v"


=== Release 1.2.6, January 18, 2000.

- The conversion scripts should now be able to cope with shell metacharacters
  (notable, ' ' and '$') in file names. This has not been thouroughly tested,
  so if you do have such files, please pay particualr scrutiny to them.


=== Release 1.2.5 January 3, 2000.

- This adds adjustments for making cvs2p4 cope correctly with post-1999
  revisions in the RCS archives being converted, as supplied by David Simon
  of Goldman Sachs. (Thanks).


=== Release 1.2.4

- In some circumstances, "p4 files" can return a different error message
  for "p4 files foo", when "foo" doesn't already exist in the depot.
  This change allows "dochanges" to work properly when this happens.
  (The precise circumstances in which the alternate message is returned
  are not yet well characterized).
   

=== Release 1.2.3

- Only attempt checkpointing if $CHECKPOINT_INTERVAL > 0. (So I can really
  turn it off in the config file!)

- Fix bug reported by Todd LaWall <toddl@SiTera.com>, wherein:

    a branched file, that has not been changed since the branch was
    made, is dropped from the branch, if $BRANCH_FLASH is not defined
    in the cvs2p4 config file. (bug in genmetadata).


=== Release 1.2.2

- Fix spurious error reports from the final diff (p4_describe vs
  p4_describe.good) when running the test cases with r98.2.  (This was
  caused by an apparent change, in which the diffs produced by the
  r97.3 "p4 describe" include Id keyword expansions, but the r98.2
  "p4 describe" does not).


=== Release 1.2.1

- Fix bug reported by Ed Rapoport, wherein:

    "There was a problem, however, in the case of cvs files where
    there were at least two branches with the second branch branching
    off the first, but not yet having a delta created in the cvs file
    (an "incipient" branch) The incipient branch name (br_orca_autocal
    in the example) got applied to its parent branch (br_orca_intermed
    in the example) and the parent branch name got applied to the
    child incipient branch in perforce."


=== Release 1.2

- Implement "dochanges -s <n>" to make the converter restartable. Yeah.
  
- Added a couple of test cases for branch tags sharing tip & trunk revs.

- Reimplement revmap to do per-revision stuff, to allow for merging.

- Fix ALLTHEWAYBACK to look for the earliest non-trunk revision actually
  selected by any branch tag - not just the earliest one where a real
  branch was found.

* This was the version used during our actual main CVS -> Perforce
  conversion on 3/20-3/21 1998.


=== Release 1.1.1, March 10, 1998

- Damn. The fix for multi-binary detection was not complete. It is now.
  Really. At least it had better be, I'm about to convert 25K p4 changes
  worth of our real source with this sucker...


=== Release 1.1, March 10, 1998

- Change conversion client name from "dochanges" to "cvs2p4"

- The CVS trunk is now created as "main" in the Perforce depot.

- Converts "$Header: //guest/daniel_sherwood/cvs2p4/NEWS#1 $" to "$Id: //guest/daniel_sherwood/cvs2p4/NEWS#1 $" for text files.

- Added support for "vendor" branches (RCS branch 1.1.1); becomes branch
  "import" in Perforce.

- Added SYM_SPECIAL support for selectively importing top level subdirs
  of a CVS module via symlinks.

- Optimizations for genchanges, which help *lots( with huge checkins
  of vendor-supplied branches (I.e., where there are many changes with
  large numbers of files).

- Fixed a bug in genchanges such that, for purposes of change grouping,
  all revisions were considered to have happened in the midnight hour
  (plus the actual number of minutes after the hour at which they actually
  occurred). Taken with the other grouping hueristics, this was pretty
  benign, I think, but it's fixed now.

- Fixed a bug wherein checkppoints were always trying to checkpoint the
  server at port 1666 on the host running the server.

- Also, *only* do checkpoints at NetApp, 'cause they depend p4d_admin!

- Take a checkpoint at the very end

- Now detects binary files in additional ways:
    perl -B operator
    known list of binary file extensions (hardcoded into dochanges for now)
  (This helps where binaries were checked in to CVS but nobody told CVS
  by selecting a binary keyword expansion mode).

- The diffs in the test stuff in 1.0.1 and 1.0.2 was inadvertantly disabled,
  so you could get false PASSes. Oops. Fixed.
  

=== Release 1.0.2, February 9, 1998

- Incorporate README typos fixes from James Strickland

- tests/* executables find Perl via $PATH

- Remove dup entry for test/changes.good from MANIFEST

- Remove "." from $check_submits in bin/dochanges (the "." was there for
  debugging, and, in effect, disables all output error checks on submits!


=== Release 1.0.1, February 3, 1998

- Incorporate James Strickland's README edits

- make bin/* kxtext

- bin/* script now find perl via PATH (it must be perl5 or they
  will fail).

- MANIFEST doesn't try to check checksums on FreeBSD systems.

- Added $CO to the test/config template file for specifying where to
  find the RCS "co" command

- CHECKPOINT_INTERVAL defaults to "10" for running the test config,
  but "0" otherwise in the test/config template.


=== Release 1.0, January 30, 1998

- Contains several bug fixes you really want if you intend to use this
  for real.

- Verified the results of a complete conversion of the NetApp Data ONTAP
  source base, by converting then doing file-by file comparisons of
  the results of checking trees out from both CVS and Perforce, across
  several branches.

- Added minimal user documentation in the README file.

- Added a minimal automated test script.

- Placed under the Artistic license.


=== Release 0.5, December 1997

This was an informal release to Perforce, so James could see what it
was like.
