Tailor is a tool that supports conversion between a variety of systems. It's available at http://www.darcs.net/DarcsWiki/Tailor.
Example Tailor conversion from CVS
This is tested with Mercurial 0.7 and Tailor 0.9.18
mkdir -p /path/to/hg/repo cd /path/to/hg/repo tailor -v --source-kind cvs --target-kind hg --repository $REP --module MODULENAME -r INITIAL > MODULENAME.tailor vi MODULENAME.tailor
Now you will at least need to change subdir from . to MODULENAME, and remove /MODULENAME from root-directory in the MODULENAME.tailor file. You will probably also want to add the line:
patch-name-format = %(revision)s
at the end of the "project" section to get your cvs checkin comments in the patch summaries. Type man tailor and search for patch-name-format to learn more about this. When done editing the config file type:
tailor --configfile MODULENAME.tailor
When this is done, you should have a working Mercurial repository that matches the trunk of the CVS archive you have been using. The --repository option gets passed to CVS via the -d option, so anything that works for $CVSROOT will for for --repository.
Be aware that the last stage of this script will take a long time to run. Also, local access to the CVS repository instead of remote access may make it significantly faster.
Things to know:
-D turns on debugging mode, printing each executed command. Good way to understand what Tailor is doing, but produces an invalid config file is used in the first tailor command above.
-v verbose, echo the changelogs as well as the commands being run (convenient for understanding progress)
- Don't do the above process where /path/to/hg/ contains a cvs checkout in a directory with the same name as MODULENAME (as in, /path/to/hg/MODULENAME already exists). Weird things happen.
Tailor config files
A very convenient way to use Tailor is through ini style config files. An example file like the following could be used to convert from a cvs repo to a hg one:
[DEFAULT] patch-name-format = %(revision)s verbose = True encoding = iso-8859-15 [mutt_hg] root-directory = /home/brendan/hg/mutt source = cvs:source target = hg:target [cvs:source] module = mutt repository = :pserver:anonymous@myproject.server.net:/cvsroot/mutt/cvs [hg:target] encoding = utf-8
