Database Backend
----------------
-git-cvsserver uses one database per git head (i.e. CVS module) to
-store information about the repository for faster access. The
-database doesn't contain any persistent data and can be completely
-regenerated from the git repository at any time. The database
-needs to be updated (i.e. written to) after every commit.

+If the commit is done directly by using `git` (as opposed to
+using 'git-cvsserver') the update will need to happen on the

access method and requested operation.
That means that even if you offer only read access (e.g. by using
-the pserver method), git-cvsserver should have write access to
+the pserver method), 'git-cvsserver' should have write access to
the database to work reliably (otherwise you need to make sure
-that the database is up-to-date any time git-cvsserver is executed).
+that the database is up-to-date any time 'git-cvsserver' is executed).
By default it uses SQLite databases in the git directory, named
`gitcvs.<module_name>.sqlite`. Note that the SQLite backend creates
temporary files in the same directory as the database file on
write so it might not be enough to grant the users using
-git-cvsserver write access to the database file without granting
+'git-cvsserver' write access to the database file without granting
them write access to the directory, too.
+The database can not be reliably regenerated in a
+consistent form after the branch it is tracking has changed.
+Example: For merged branches, 'git-cvsserver' only tracks
+one branch of development, and after a 'git-merge' an
+incrementally updated database may track a different branch
+than a database regenerated from scratch, causing inconsistent
+CVS revision numbers. `git-cvsserver` has no way of knowing which
+branch it would have picked if it had been run incrementally
+pre-merge. So if you have to fully or partially (from old
+backup) regenerate the database, you should be suspicious
+of pre-existing CVS sandboxes.
+
You can configure the database backend with the following
configuration variables:

its documentation if changing these variables, especially

Alternatively, you can just use the non-standard extssh protocol that Eclipse
offer. In that case CVS_SERVER is ignored, and you will have to replace

Clients known to work
---------------------
Legacy monitoring operations are not supported (edit, watch and related).
Exports and tagging (tags and branches) are not supported at this stage.
-The server should set the '-k' mode to binary when relevant, however,
-this is not really implemented yet. For now, you can force the server
-to set '-kb' for all files by setting the `gitcvs.allbinary` config
-variable. In proper GIT tradition, the contents of the files are
-always respected. No keyword expansion or newline munging is supported.
+CRLF Line Ending Conversions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default the server leaves the '-k' mode blank for all files,
+which causes the cvs client to treat them as a text files, subject
+to crlf conversion on some platforms.
+
+You can make the server use `crlf` attributes to set the '-k' modes
+for files by setting the `gitcvs.usecrlfattr` config variable.
+In this case, if `crlf` is explicitly unset ('-crlf'), then the
+server will set '-kb' mode for binary files. If `crlf` is set,
+then the '-k' mode will explicitly be left blank. See
+also linkgit:gitattributes[5] for more information about the `crlf`
+attribute.
+
+Alternatively, if `gitcvs.usecrlfattr` config is not enabled
+or if the `crlf` attribute is unspecified for a filename, then
+the server uses the `gitcvs.allbinary` config for the default setting.
+If `gitcvs.allbinary` is set, then file not otherwise
+specified will default to '-kb' mode. Otherwise the '-k' mode
+is left blank. But if `gitcvs.allbinary` is set to "guess", then
+the correct '-k' mode will be guessed based on the contents of
+the file.
+
+For best consistency with 'cvs', it is probably best to override the
+defaults by setting `gitcvs.usecrlfattr` to true,
+and `gitcvs.allbinary` to "guess".
