When gitweb is used as a DirectoryIndex, it attempts to strip
PATH_INFO on its own, as $cgi->url() fails to do so.
However, it fails to account for the fact that PATH_INFO has
already been URL-decoded by the web server, but the value
returned by $cgi->url() has not been. This causes the stripping
to fail whenever the URL contains encoded characters.
To see this in action, setup gitweb as a DirectoryIndex and
then use it on a repository with a directory containing a
space in the name. Navigate to tree view, examine the gitweb
generated html and you'll see a link such as:
<a href="/test.git/tree/HEAD:/directory with spaces">directory with spaces</a>
When clicked on, the browser will URL-encode this link, giving
a $cgi->url() of the form:
/test.git/tree/HEAD:/directory%20with%20spaces
While PATH_INFO is:
/test.git/tree/HEAD:/directory with spaces
Fix this by calling unescape() on both $my_url and $my_uri before
stripping PATH_INFO from them.

Since v1.7.0-rc2~11 (git-svn: persistent memoization, 2010-01-30),
git-svn has maintained some private per-repository caches in
.git/svn/.caches to avoid refetching and recalculating some
mergeinfo-related information with every 'git svn fetch'.
This memoization can cause problems, e.g consider the following case:
SVN repo:
... - a - b - c - m <- trunk
\ /
d - e <- branch1
The Git import of the above repo is at commit 'a' and doesn't know about
the branch1. In case of an 'git svn rebase', only the trunk of the
SVN repo is imported. During the creation of the git commit 'm', git svn
uses the svn:mergeinfo property and tries to find the corresponding git
commit 'e' to create 'm' with 'c' and 'e' as parents. But git svn rebase
only imports the current branch so commit 'e' is not imported.
Therefore git svn fails to create commit 'm' as a merge commit, because one
of its parents is not known to git. The imported history looks like this:
... - a - b - c - m <- trunk
A later 'git svn fetch' to import all branches can't rewrite the commit 'm'
to add 'e' as a parent and to make it a real git merge commit, because it
was already imported.
That's why the imported history misses the merge and looks like this:
... - a - b - c - m <- trunk
\
d - e <- branch1
Right now the only known workaround for importing 'm' as a merge is to
force reimporting 'm' again from SVN, e.g. via
$ git svn reset --revision $(git find-rev $c)
$ git svn fetch
Sadly, this is where the behavior has regressed: git svn reset doesn't
invalidate the old mergeinfo cache, which is no longer valid for the
reimport, which leads to 'm' beeing imprted with only 'c' as parent.
As solution to this problem, this commit invalidates the mergeinfo cache
to force correct recalculation of the parents.
During development of this patch, several ways for invalidating the cache
where considered. One of them is to use Memoize::flush_cache, which will
call the CLEAR method on the underlying Memoize persistency implementation.
Sadly, neither Memoize::Storable nor the newer Memoize::YAML module
introduced in 68f532f4ba could optionally be used implement the
CLEAR method, so this is not an option.
Reseting the internal hash used to store the memoized values has the same
problem, because it calls the non-existing CLEAR method of the
underlying persistency layer, too.
Considering this and taking into account the different implementations
of the memoization modules, where Memoize::Storable is not in our control,
implementing the missing CLEAR method is not an option, at least not if
Memoize::Storable is still used.
Therefore the easiest solution to clear the cache is to delete the files
on disk in 'git svn reset'. Normally, deleting the files behind the back
of the memoization module would be problematic, because the in-memory
representation would still exist and contain wrong data. Fortunately, the
memoization is active in memory only for a small portion of the code.
Invalidating the cache by deleting the files on disk if it isn't active
should be safe.

dcommit didn't handle errors returned by SVN and coped very
poorly with concurrent commits that appear in SVN repository
while dcommit was running. In both cases it left git repository
in inconsistent state: index (which was reset with `git reset
--mixed' after a successful commit to SVN) no longer matched the
checkouted tree, when the following commit failed or needed to be
rebased. See http://bugs.debian.org/676904 for examples.
This patch fixes the issues by:
- introducing error handler for dcommit. The handler will try
to rebase or reset working tree before returning error to the
end user. dcommit_rebase function was extracted out of cmd_dcommit
to ensure consistency between cmd_dcommit and the error handler.
- calling `git reset --mixed' only once after all patches are
successfully committed to SVN. This ensures index is not touched
for most of the time of dcommit run.

Commit ff5effdf taught both clients and servers of the git protocol
to send an "agent" capability that just advertises their version for
statistics and debugging purposes. The protocol-capabilities.txt
document however indicates that the client's advertisement is
actually a response, and should never include capabilities not
mentioned in the server's advertisement.
Adding the unconditional advertisement in the server programs was
OK, then, but the clients broke the protocol. The server
implementation of git-core itself does not care, but at least one
does: the Google Code git server (or any server using Dulwich), will
hang up with an internal error upon seeing an unknown capability.
Instead, each client must record whether we saw an agent string from
the server, and respond with its agent only if the server mentioned
it first.

If we have capabilities to send to the server, we send the
regular "want" line followed by a NUL, then the
capabilities; otherwise, we do not even send the NUL.
However, when checking whether we want to send the "quiet"
capability, we check args->quiet, which is wrong. That flag
only tells us whether the client side wanted to be quiet,
not whether the server supports it (originally, in c207e34f,
it meant both; however, that was later split into two flags
by 01fdc21f).
We still check the right flag when actually printing
"quiet", so this could only have two effects:
1. We might send the trailing NUL when we do not otherwise
need to. In theory, an antique pre-capability
implementation of git might choke on this (since the
client is instructed never to respond with capabilities
that the server has not first advertised).
2. We might also want to send the quiet flag if the
args->progress flag is false, but this code path would
not trigger in that instance.
In practice, it almost certainly never matters. The
report-status capability dates back to 2005. Any real-world
server is going to advertise that, and we will always
respond with at least that capability.
