2012-10-16cvsserver: support -r and sticky tags for most operationsLibravatar Matthew Ogilvie1-203/+510
- Split off prepDirForOutput for "update" and "commit". Some low level protocol details were changed to more closely resemble CVS even in non-tagged cases. Hopefully it still works with finicky clients like Eclipse. - Substantial changes to "diff". The output is now closer to standard CVS (including exit status), and can be used as a patch, but there are still a number of differences compared to CVS. - Tweaks to "add", "remove", "status", and "commit". - FUTURE: CVS revision numbers for branches simply encode git commit IDs in a way that resembles CVS revision numbers, dropping all normal CVS structural relations between different revision numbers. - FUTURE: "log" doesn't try to work properly at all with branches and tags. - FUTURE: "annotate" probably doesn't work with branches or tags either (untested)?

2012-10-16cvsserver: define a tag name character escape mechanismLibravatar Matthew Ogilvie1-0/+91
CVS tags are officially only allowed to use [-_0-9A-Za-f]. Git refs commonly uses other characters, especially [./]. Such characters need to be escaped from CVS in order to be referenced.

2012-10-16cvsserver: cvs add: do not expand directory argumentsLibravatar Matthew Ogilvie1-2/+0
Standard "cvs add" never does any recursion. With standard cvs, "cvs add dir" will either add just the "dir" to the repository, or error out. Prior to this change, git-cvsserver would try to recurse (perhaps re-adding sandbox-removed files?) into the existing directory instead.

2012-10-16cvsserver: use whole CVS rev number in-process; don't strip "1." prefixLibravatar Matthew Ogilvie1-103/+122
Keep track of the whole CVS revision number in-process. This will clarify code when we start handling non-linear revision numbers later. There is one externally visible change: conflict markers after an update will now include the full CVS revision number, including the "1." prefix. It used to leave off the prefix. Other than the conflict marker, this change doesn't effect external functionality. No new features, and the DB schema is unchanged such that it continues to store just the stripped rev numbers (without prefix).

2010-09-27perl: bump the required Perl version to 5.8 from 5.6.[21]Libravatar Ævar Arnfjörð Bjarmason1-0/+1
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already used the three-arg form of open() which was introduced in 5.6.1, but t/t9700/test.pl explicitly depended on 5.6.2. However git-add--interactive.pl has been failing on the 5.6 line since it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open syntax: sub run_cmd_pipe { my $fh = undef; open($fh, '-|', @_) or die; return <$fh>; } Which when executed dies on "Can't use an undefined value as filehandle reference". Several of our tests also fail on 5.6 (even more when compiled with NO_PERL_MAKEMAKER=1): t2016-checkout-patch.sh t3904-stash-patch.sh t3701-add-interactive.sh t7105-reset-patch.sh t7501-commit.sh t9700-perl-git.sh Our code is bitrotting on 5.6 with no-one interested in fixing it, and pinning us to such an ancient release of Perl is keeping us from using useful features introduced in the 5.8 release. The 5.6 series is now over 10 years old, and the 5.6.2 maintenance release almost 7. 5.8 on the other hand is more than 8 years old. All the modern Unix-like operating systems have now upgraded to it or a later version, and 5.8 packages are available for old IRIX, AIX Solaris and Tru64 systems.

2009-12-30CVS Server: Support reading base and roots from environmentLibravatar Phil Miller1-1/+21
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.

2009-01-30git-cvsserver: run post-update hook *after* update.Libravatar Stefan Karpinski1-2/+2
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.

2009-01-30git-cvsserver: handle CVS 'noop' command.Libravatar Stefan Karpinski1-0/+1
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.

2009-01-05cvsserver: change generation of CVS author namesLibravatar Fabian Emmes1-3/+9
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.
