**cvs2gitdump.py and cvs2svndump.py can run on Python 3 now. But
"rcsparse" doesn't support running on Python 3. For OpenBSD, use
py3-rcsparse-20151027p1 package which will be available for 6.9.**
cvs2gitdump
===========
A small python script which imports cvs tree into git repository.
Pros:
- Small footprint
- Supports incremental import. It's very fast
- Converts tags on HEAD
- Everything is done in memory
Cons:
- Doesn't convert any branches
An alternative to
- [git-cvs](https://github.com/ustuehler/git-cvs)
- [cvs2svn](http://cvs2svn.tigris.org/)
- [cvs-fast-export](http://www.catb.org/~esr/cvs-fast-export/cvs-fast-export.html)
Prerequisite:
- [rcsparse](https://github.com/corecode/rcsparse)
Usage
-----
usage: cvs2gitdump [-ah] [-z fuzz] [-e email_domain] [-E log_encodings]
[-k rcs_keywords] [-b branch] [-m module] [-l last_revision]
cvsroot [git_dir]
### Options
* -a
As the default the script will only use commits 10 minutes older than
the most recent commit because recent commits may not stable if the
repository is changing. This option will change this behavior, it
will use the entire commits.
* -b branch
The branch name of the git repository which is used for incremental
import.
* -h
Show the usage.
* -z fuzz
When the script collects changesets from CVS repository, commits by
the same author, using the same log message and within ``fuzz``
seconds are collected into the same changeset. 300 (seconds) is used
as the default.
* -e email_domain
Append the email domain to the author.
* -E log_encodings
Specify the character encodings used for decoding CVS logs. Multiple
encodings can be specified by spearating with ','. Specified encodings
are used in order for decoding the log. Default is 'utf-8,iso-8859-1'
* -k rcs_keywords
Add an extra RCS keyword which are used by CVS. The script
substitutes the RCS keyword by the same way as $Id$.
* -m module
Specify the target module name in the target cvsroot. The script will
dump only the directory specified by this option.
* -l last_rev
Specify the last revision which is used for finding the last change
set in the CVS tree. Specify in SHA-1.
* cvsroot
The target cvsroot or the sub directory of the cvsroot. The script treats
this directory as the root directory.
* git_dir
The git repository. Specify this for incremental import.
Example
-------
First import:
% git init --bare /git/openbsd.git
% python cvs2gitdump.py -k OpenBSD -e openbsd.org /cvs/openbsd/src > openbsd.dump
% git --git-dir /git/openbsd.git fast-import < openbsd.dump
Periodic import:
% doas reposync
% python cvs2gitdump.py -k OpenBSD -e openbsd.org /cvs/openbsd/src /git/openbsd.git > openbsd2.dump
% git --git-dir /git/openbsd.git fast-import < openbsd2.dump
cvs2svndump
===========
A small python script which imports cvs tree into subversion repository.
Pros:
- Small footprint
- Supports incremental import is supported. It's very fast
- Everythings is done in memory
Cons:
- Doesn't convert tags and branches
Prerequirement:
- [rcsparse](http://gitorious.org/fromcvs/rcsparse)
- svn (Python interface for subversion)
Usage
-----
usage: cvs2svndump [-ah] [-z fuzz] [-e email_domain] [-E log_encodings]
[-k rcs_keywords] [-m module] cvsroot [svnroot svnpath]]
### Options
* -a
As the default the script will only use commits 10 minutes older than
the most recent commit because recent commits may not stable if the
repository is changing. This option will change this behavior, it
will use the entire commits.
* -h

* -z fuzz
When the script collects changesets from CVS repository, commits by
the same author, using the same log message and within ``fuzz``
seconds are collected into the same changeset. 300 (seconds) is used
as the default.
* -e email_domain

* -E log_encodings
Specify the character encodings used for decoding CVS logs. Multiple
encodings can be specified by spearating with ',' and they are used in
order. Default is 'utf-8,iso-8859-1'
* -k rcs_keywords
Add an extra RCS keyword which are used by CVS. The script
substitutes the RCS keyword by the same way as $Id$.
* -m module
Specify the target module name in the target cvsroot. The script will
dump only the directory specified by this option.
* cvsroot
The target cvsroot or the sub directory of the cvsroot. The script treats
this directory as the root directory.
* svn_dir svn_path
Specify the svn repository and path. Specify these for incremental
import. When the script searches the last commit, it excepts the commits
whose author are 'svnadmin'. Use 'svnadmin' for manually fixing.
Example
-------
First import:
% python cvs2svndump.py -k OpenBSD /cvs/openbsd/src > openbsd.dump
% svnadmin create /svnrepo
% svn mkdir --parents -m 'mkdir /vendor/openbsd/head/src' file:///svnrepo/vendor/openbsd/head/src
% svnadmin load --parent-dir /vendor/openbsd/head/src /svnrepo < openbsd.dump
Periodic import:
% doas cvsync
% python cvs2svndump.py -k OpenBSD /cvs/openbsd/src file:///svnrepo vendor/openbsd/head/src > openbsd2.dump
% svnadmin load /svnrepo < openbsd2.dump
