This plugin allows ikiwiki to use [[!wikipedia desc="CVS" Concurrent Versions System]] as an [[rcs]].
Usage
- Install cvsps, [[!cpan IPC::Cmd]], [[!cpan String::ShellQuote]], and cvsweb or the like.
- Adjust CVS-related parameters in your setup file.
Consider creating $HOME/.cvsrc if you don't have one already; the plugin doesn't need it, but you yourself might. Here's a good general-purpose one:
cvs -q
checkout -P
update -dP
diff -u
rdiff -u
Implementation details
cvs.pm started life as a copy of [[3.14159|news/version_3.14159]]'s svn.pm.IkiWiki.pm:wiki_file_prune_regexps avoids copying CVS metadata into $DESTDIR.- [[ikiwiki-makerepo]]:
- creates a repository,
- imports
$SRCDIR into top-level module ikiwiki (vendor tag IKIWIKI, release tag PRE_CVS),
- creates a small post-commit wrapper to prevent
cvs add <directory> from being seen by ikiwiki's [[post-commit]] hook (and avoid cvs locking against itself),
- configures the wrapper itself as a post-commit hook in
CVSROOT/loginfo.
- CVS multi-directory commits happen separately; the post-commit hook sees only the first directory's changes in time for [[recentchanges|plugins/recentchanges]]. The next run of
ikiwiki --setup will correctly re-render such a recentchanges entry. It should be possible to solve this problem with NetBSD's commit_prep and log_accum scripts (see below).
To do
- Add automated tests. (Blindly adding svn-like tests to
t/file_pruned.t doesn't do the trick.)
- If the argument to
cvs add smells like a binary file, cvs add -kb it (for [[plugins/attachment]] support).
- Don't slurp the entire
cvsps output into memory (!).
- Instead of resource-intensively scraping changesets with
cvsps, have ikiwiki-makerepo set up NetBSD-like log_accum and commit_prep scripts that coalesce and keep records of commits. cvsps can be used as a fallback for repositories without such records.
- Perhaps prevent web edits from attempting to create
.../CVS/foo.mdwn (and .../cvs/foo.mdwn on case-insensitive filesystems); thanks to the CVS metadata directory, the attempt will fail anyway (and much more confusingly) if we don't.
