47543d161e git svn: ignore partial svn:mergeinfo
Currently this is cosmetic change - the merges are ignored, becuase the methods
(lookup_svn_merge, find_rev_before, find_rev_after) are failing on comparing text with number.

See http://www.open.collab.net/community/subversion/articles/merge-info.html
Extract:
The range r30430:30435 that was added to 1.5.x in this merge has a '*' suffix for 1.5.x\www.
This '*' is the marker for a non-inheritable mergeinfo range.
The '*' means that only the path on which the mergeinfo is explicitly set has had this range merged into it.

68868ff573 Move Git::SVN::get_tz to Git::get_tz_offset
This function has utility outside of the SVN module for any routine
that needs the equivalent of GNU strftime's %z formatting option.
Move it to the top-level Git.pm so that non-SVN modules don't need to
import the SVN module to use it.

The rename makes the purpose of the function clearer.

14d3ce1120 git-svn.perl: keep processing all commits in parents_exclude
This fixes a bug where git finds the incorrect merge parent.  Consider a
repository with trunk, branch1 of trunk, and branch2 of branch1.
Without this change, git interprets a merge of branch2 into trunk as a
merge of branch1 into trunk.

f271fad266 git-svn.perl: consider all ranges for a given merge, instead of only tip-by-tip
Consider the case where you have trunk, branch1 of trunk, and branch2 of
branch1.  trunk is merged back into branch2, and then branch2 is
reintegrated into trunk.  The merge of branch2 into trunk will have
svn:mergeinfo property references to both branch1 and branch2.  When
git-svn fetches the commit that merges branch2 (check_cherry_pick),
it is necessary to eliminate the merged contents of branch1 as well as
branch2, or else the merge will be incorrectly ignored as a cherry-pick.

61b472ed8b git svn: reset invalidates the memoized mergeinfo caches
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.

705b49cb81 git-svn: canonicalize newly-minted URLs
Go through all the spots that use the new add_path_to_url() to
make a new URL and canonicalize them.

* copyfrom_path has to be canonicalized else find_parent_branch
  will get confused

* due to the `canonicalize_url($full_url) ne $full_url)` line of
  logic in gs_do_switch(), $full_url is left alone until after.

At this point SVN 1.7 passes except for 3 tests in
t9100-git-svn-basic.sh that look like an SVN bug to do with
symlinks.

9c27a57b2d git-svn: replace URL escapes with canonicalization
The old hand-rolled URL escape functions were inferior to
canonicalization functions.

Continuing to move towards getting everything canonicalizing the same way.

* Git::SVN->init_remote_config and Git::SVN::Ra->minimize_url both
  have to canonicalize the same way else init_remote_config
  will incorrectly think they're different URLs causing
  t9107-git-svn-migrate.sh to fail.

93c3fcbe4d git-svn: attempt to mimic SVN 1.7 URL canonicalization
Previously, our URL canonicalization didn't do much of anything.
Now it actually escapes and collapses slashes.  This is mostly a cut & paste
of escape_url from git-svn.

This is closer to how SVN 1.7's canonicalization behaves.  Doing it with
1.6 lets us chase down some problems caused by more effective canonicalization
without having to deal with all the other 1.7 issues on top of that.

* Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote
  will think they're different.

* The SVN remote is now written to the git config canonicalized.  That
  should be ok.  Adjust a test to account for that.

This canonicalizes paths and urls as early as possible so we don't
have to remember to do it at the point of use.  It will fix a swath

Its ok to double canonicalize things.

SVN 1.7 still fails, still not worrying about that.

ca475a61f8 git-svn: add join_paths() to safely concatenate paths
Otherwise you might wind up with things like...

    my $path1 = undef;
    my $path2 = 'foo';
    my $path = $path1 . '/' . $path2;

creating '/foo'.  Or this...

    my $path1 = 'foo/';
    my $path2 = 'bar';
    my $path = $path1 . '/' . $path2;

creating 'foo//bar'.

Could have used File::Spec, but I'm shying away from it due to SVN
1.7's pickiness about paths.  Felt it would be better to have our own
we can control completely.
