  CVS Server: Support reading base and roots from environment
2010-01-10 08:52:37 -08:00
Sergei Organov 8e4c4e7dc3 cvsserver: make the output of 'update' more compatible with cvs.
Native cvs update outputs the string "cvs update: Updating <DIR>" for
every directory it processes (to stderr) unless -q or -Q is given on
comman-line. This is used, e.g., by emacs pcl-cvs to split files by
directory. This commit implements this feature in cvsserver.

Phil Miller 03bd0d601e CVS Server: Support reading base and roots from environment
The Gitosis single-account Git/ssh hosting system runs git commands
through git-shell after confirming that the connecting user is
authorized to access the requested repository. This works well for
upload-pack and receive-pack, which take a repository argument through
git-shell. This doesn't work so well for `cvs server', which is passed
through literally, with no arguments. Allowing arguments risks
sneaking in `--export-all', so that restriction should be maintained.

Despite that, passing a repository root is necessary for per-user
access control by the hosting software, and passing a base path
improves usability without weakening security. Thus, git-cvsserver
needs to come up with these values at runtime by some other
means. Since git-shell preserves the environment for other purposes,
the environment can carry these arguments as well.

Thus, modify git-cvsserver to read $GIT_CVSSERVER_{BASE_PATH,ROOT} in
the absence of equivalent command line arguments.

Stefan Karpinski ad8c3477b8 git-cvsserver: run post-update hook *after* update.
CVS server was running the hook before the update action was
actually done. This performs the update before the hook is called.

The original commit that introduced the current incorrect behavior
was 394d66d "git-cvsserver runs hooks/post-update". The error in
ordering of the hook call appears to have gone unnoticed, but since
git-cvsserver is supposed to emulate receive-pack, it stands to
reason that the hook should be run *after* the update. Since this
behavior is inconsistent with recieve-pack, users are either:

  1) not using post-update hooks with git-cvsserver;
  2) using post-update hooks that don't care whether they are
     called before or after the actual update occurs;
  3) using post-update hooks *only* with git-cvsserver, and
     relying on the hook being called just before the update.

This patch would affect only users in case 3. These users are
depending on fairly obviously wrong behavior, and moreover they can
simply change their current post-update into post-recieve hooks,
and their systems will work correctly again.

Stefan Karpinski 499cc56a60 git-cvsserver: handle CVS 'noop' command.
The CVS protocol documentation, found at

  http://www.wandisco.com/techpubs/cvs-protocol.pdf

states the following about the 'noop' command:

  Response expected: yes. This request is a null command
  in the sense that it doesn't do anything, but merely
  (as with any other requests expecting a response) sends
  back any responses pertaining to pending errors, pending
  Notified responses, etc.

In accordance with this, the correct way to handle the 'noop'
command, when issued by a client, is to call req_EMPTY.

The 'noop' command is called by some CVS clients, notably
TortoiseCVS, thus making it desirable for git-cvsserver to
respond to the command rather than choking on it as unknown.

Fabian Emmes d500a1ee8f cvsserver: change generation of CVS author names
CVS username is generated from local part email address.
We take the whole local part but restrict the character set to the
Portable Filename Character Set, which is used for Unix login names
according to Single Unix Specification v3.

This will obviously report different usernames from existing repositories
for commits with the local part of the author e-mail address that contains
characters outside the PFCS.  Hopefully this won't break an old CVS
checkout from an earlier version of git-cvsserver, because the names are
always shown afresh to the CVS clients and not kept on the client side.

But this is currently shown in the dashed form.  So if you just

Make git-cvsserver understand some options inspired by

Also allow the caller to specify a whitelist of allowed

While already adding option parsing also support the common

Rationale:

While the gitcvs.enabled configuration option already
offers means to limit git-cvsserver access to a repository,
there are some use cases where other methods of access
control prove to be more useful.

E.g. if setting up a pserver for a collection of public
repositories one might want limit the exported repositories
to exactly the directory this collection is located whithout
having to worry about other repositories that might lie around
with the configuration variable set (never trust your users ;)

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.

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.

Blowing away my SQLLite database and rebuilding all tables with

Since the indexes shouldn't hurt performance on small repositories
and always helps on larger repositories we should just always create

Martin Langhoff 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.
