Frank Lichtenheld 24a97d84ad cvsserver: Handle 'cvs login'
Since this is a trivial variation of the general pserver
authentication, there is really no reason not to support
it.

Frank Lichtenheld 460c6996e2 cvsserver: Don't send mixed messages to clients
After we send I HATE YOU we should probably exit and not happily
continue with I LOVE YOU and further communication.

Most clients will probably just exit and ignore everything we
send after the I HATE YOU and it is not a security problem
either because we don't really care about the user name anyway.

But it is still the right thing to do.

[jc: with a minor fixup to its exit code...]

Frank Lichtenheld f987afa8fe cvsserver: Limit config parser to needed options
Change the configuration parser so that it ignores
everything except for ^gitcvs.((ext|pserver).)?
This greatly reduces the risk of failing while
parsing some unknown and irrelevant config option.

The bug that triggered this change was that the
parsing doesn't handle sections that have a
subsection and a variable with the same name.

While this bug still remains, all remaining
causes can be attributed to user error, since
there are no defined variables gitcvs.ext and
gitcvs.pserver.

Frank Lichtenheld 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 '_'

Andy Parkins 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.

Andy Parkins 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.

Junio C Hamano 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.

Andy Parkins 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.

Andy Parkins 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.

Shawn Pearce 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.
