0cf611a300 cvsserver: Use DBI->table_info instead of DBI->tables
DBI->table_info is portable across different DBD backends,
DBI->tables is not.

Limit the output to objects of type TABLE.

920a449af5 cvsserver: Abort if connect to database fails
Currently all calls to the database backend make no
error checking or handling at all. At least abort
if the connection to the database failed since
there is really no way we could do anything useful

eb1780d480 cvsserver: Make the database backend configurable
Make all the different parts of the database backend connection
configurable. This adds the following string configuration variables:
- gitcvs.dbdriver
- gitcvs.dbname
- gitcvs.dbuser
- gitcvs.dbpass
The default values emulate the current behavior exactly for
backwards compatibility.
All configuration variables can also be specified for a specific
access method (i.e. in the form gitcvs.<method>.<var>)

The dbdriver/dbuser/dbpass variables are added for completness.
No other backend than SQLite is tested yet.
The dbname variable on the other hand is useful with this backend
already (to not discriminate against other possible backends
it was not splitted in dbdir and dbfile).

Both dbname and dbuser support dynamic variable substitution where
the available variables are:
%m -- the CVS 'module' (i.e. GIT 'head') worked on
%a -- CVS access method used (i.e. 'ext' or 'pserver')
%u -- User name of the user invoking git-cvsserver
%G -- .git directory name
%g -- .git directory name, mangled to be used in a filename,
      currently this substitutes all chars except for [\w.-]
      with '_'

8538e876b1 cvsserver: Make always-binary mode a config file option
The config option gitcvs.allbinary may be set to force all entries to
get the -kb flag.

In the future the gitattributes system will probably be a more
appropriate way of doing this, but that will easily slot in as the
entries lines sent to the CVS client now have their kopts set via the
function kopts_from_path().

In the interim it might be better to not just have a all-or-nothing
approach, but rather detect based on file extension (or file contents?).
That would slot in easily here as well.  However, I personally prefer
everything to be binary-safe, so I just switch the switch.

1872adabcc cvsserver: Remove trailing "\n" from commithash in checkin function
The commithash for updating the ref is obtained from a call to
git-commit-tree.  However, it was returned (and stored) with the
trailing newline.  This meant that the later call to git-update-ref that
was trying to update to $commithash was including the newline in the
parameter - obviously that hash would never exist, and so git-update-ref
would always fail.

The solution is to chomp() the commithash as soon as it is returned by
git-commit-tree.

ada5ef3b48 Make 'cvs ci' lockless in git-cvsserver by using git-update-ref
This makes "ci" codepath lockless by following the usual
"remember the tip, do your thing, then compare and swap at the
end" update pattern using update-ref.  Incidentally, by updating
the code that reads where the tip of the head is to use
show-ref, it makes it safe to use in a repository whose refs are
pack-pruned.

I noticed that other parts of the program are not yet pack-refs
safe, but tried to keep the changes to the minimum.

b2741f63d4 Have git-cvsserver call hooks/update before really altering the ref
git-cvsserver is analogous to git-receive-pack; a checking from a cvs
client to a central server is like a git-push from a working repository.
Therefore it's nice to use the same access control (and email sending)
that a receive-pack would perform.

This patch tests for an executable update hook; if it is it is run with
the ref being updated and the old and new hashes as normal.  If the
update hook returns an error code the update is aborted and the ref is
never updated.  The cvsserver returns "error 1" to the client to signal
there was an EPERM error.

535514f1f3 New files in git weren't being downloaded during CVS update
If a repository was checked out via git-cvsserver and then later a new
file is added to the git repository via some other method; a CVS update
wasn't fetching the new file.

It would be reported as a new file as
 A some/dir/newfile.c
but would never appear in the directory.

The problem seems to be that git-cvsserver was treating these two cases
identically, as "A" type results.

1. New file in repository
2. New file locally

In fact, traditionally, case 1 is treated as a "U" result, and case 2
only is treated as an "A" result.  "A", should just report that the file
is added locally and then skip that file during an update as there is
(of course) nothing to send.

In both these cases there is no working revision, so the checking for
"is there no working revision" will return true.  The test for case 2
needs refining to say "if there is no working revision and no upstream
revision".  This patch does just that, leaving case 1 to be handled by
the normal "U" handler.

I've also updated the log message to more accurately describe the
operation.  i.e. that "A" means that content is scheduled for addition;
not that it actually has been added.

178e015c05 Use column indexes in git-cvsserver where necessary.
Tonight I found a git-cvsserver instance spending a lot of time in
disk IO while trying to process operations against a Git repository
with >30,000 objects contained in it.

Blowing away my SQLLite database and rebuilding all tables with
indexes on the attributes that git-cvsserver frequently runs queries
against seems to have resolved the issue quite nicely.

Since the indexes shouldn't hurt performance on small repositories
and always helps on larger repositories we should just always create
them when creating the revision storage tables.

* Added extra parameter to filenamesplit() to force stripping of "prepended" directory name. This ensures commits/updates etc work from any directory in the source tree.
* Modified argsfromdir() so it is "always" called. This means that when the client specifies a directory, the method can detect this and behave accordingly (this is currently only implemented for the '.' directory)

3fda8c4cc7 Introducing git-cvsserver -- a CVS emulator for git.
git-cvsserver is highly functional. However, not all methods are implemented,
and for those methods that are implemented, not all switches are implemented.
All the common read operations are implemented, and add/remove/commit are
supported.

Testing has been done using both the CLI CVS client, and the Eclipse CVS
plugin. Most functionality works fine with both of these clients.

Currently git-cvsserver only works over SSH connections, see the
Documentation for more details on how to configure your client. It
does not support pserver for anonymous access but it should not be
hard to implement. Anonymous access will need tighter input validation.

In our very informal tests, it seems to be significantly faster than a real
CVS server.

This utility depends on a version of git-cvsannotate that supports -S and on
DBD::SQLite.
