0382318424 contrib/git-svn: stabilize memory usage for big fetches
We should be safely able to import histories with thousands
of revisions without hogging up lots of memory.

With this, we lose the ability to autocorrect mistakes when
people specify revisions in reverse, but it's probably no longer
a problem since we only have one method of log parsing nowadays.

I've added an extra check to ensure that revision numbers do
increment.

Also, increment the version number to 0.11.0.  I really should
just call it 1.0 soon...

ac74905064 contrib/git-svn: allow rebuild to work on non-linear remote heads
Because committing back to an SVN repository from different
machines can result in different lineages, two different
repositories running git-svn can result in different commit
SHA1s (but of the same tree).  Sometimes trees that are tracked
independently are merged together (usually via children),
resulting in non-unique git-svn-id: lines in rev-list.

779b144625 contrib/git-svn: fix a harmless warning on rebuild (with old repos)
It's only for repositories that were imported with very early
versions of git-svn.  Unfortunately, some of those repos are out
in the wild already, so fix this warning.

7317ed906a contrib/git-svn: remove the --no-stop-on-copy flag
Output a big warning if somebody actually has a pre-1.0 version
of svn that doesn't support it.

Thanks to Yann Dirson for reminding me it still existed
and attempting to re-enable it :)

I think I subconciously removed support for it earlier...

1d52aba839 contrib/git-svn: fix svn compat and fetch args
'svn info' doesn't work with URLs in svn <= 1.1.  Now we
only run svn info in local directories.

As a side effect, this should also work better for 'init' off
directories that are no longer in the latest revision of the
repository.

svn checkout -r<revision> arguments are fixed.
Newer versions of svn (1.2.x) seem to need URL@REV as well as
-rREV to checkout a particular revision...

Add an example in the manpage of how to track directory that has
been moved since its initial revision.

A huge thanks to Yann Dirson for the bug reporting and testing
my original patch.  Thanks also to Junio C Hamano for suggesting
a safer way to use git-rev-parse.

ce4c8b24a1 contrib/git-svn: fix a copied-tree bug in an overzealous assertion
I thought passing --stop-on-copy to svn would save us from all
the trouble svn-arch-mirror had with directory (project) copies.
I was wrong, there was one thing I overlooked.

If a tree was moved from /foo/trunk to /bar/foo/trunk with no
other changes in r10, but the last change was done in r5, the
Last Changed Rev (from svn info) in /bar/foo/trunk will still be
r5, even though the copy in the repository didn't exist until
r10.

Now, if we ever detect that the Last Changed Rev isn't what
we're expecting, we'll run svn diff and only croak if there are
differences between them.

1ca72aef45 contrib/git-svn: avoid re-reading the repository uuid, it never changes
If it does change, we're screwed anyways as SVN will refuse to
commit or update.  We also never access more than one SVN
repository per-invocation, so we can store it as a global, too.

7f60b22860 contrib/git-svn: create a more recent master if one does not exist
In a new repository, the initial fetch creates a master branch
if one does not exist so HEAD has something to point to.

It now creates a master at the end of the initial fetch run,
pointing to the latest revision.  Previously it pointed to the
first revision imported, which is generally less useful.

df746c5a81 contrib/git-svn: strip 'git-svn-id:' when commiting to SVN
We regenerate and use git-svn-id: whenever we fetch or otherwise
commit to remotes/git-svn.  We don't actually know what revision
number we'll commit to SVN at commit time, so this is useless.
It won't throw off things like 'rebuild', though, which knows to
only use the last instance of git-svn-id: in a log message

ac8e0b910c contrib/git-svn: several small bug fixes and changes
* Fixed manually-edited commit messages not going to
   remotes/git-svn on sequential commits after the sequential
   commit optimization.
 * format help correctly after adding 'show-ignore'
 * sha1_short regexp matches down to 4 hex characters
   (from git-rev-parse --short documentation)
 * Print the first line of the commit message when we commit to
   SVN next to the sha1.
 * Document 'T' (type change) in the comments

69f0d91e49 contrib/git-svn: add -b/--branch switch for branch detection
I've said I don't like branches in Subversion, and I still don't.
This is a bit more flexible, though, as the argument for -b is any
arbitrary git head/tag reference.

This makes some things easier:
 * Importing git history into a brand new SVN branch.
 * Tracking multiple SVN branches via GIT_SVN_ID, even from multiple
   repositories.
 * Adding tags from SVN (still need to use GIT_SVN_ID, though).
 * Even merge tracking is supported, if and only the heads end up with
   100% equivalent tree objects.  This is more stricter but more robust
   and foolproof than parsing commit messages, imho.

2beb3cdd18 contrib/git-svn: use refs/remotes/git-svn instead of git-svn-HEAD
After reading a lengthy discussion on the list, I've come to the
conclusion that creating a 'remotes' directory in refs isn't
such a bad idea.

You can still branch from it by specifying remotes/git-svn (not
needing the leading 'refs/'), and the documentation has been
updated to reflect that.

The 'git-svn' part of the ref can of course be set to whatever
you want by using the GIT_SVN_ID environment variable, as
before.

I'm using refs/remotes/git-svn, and not going with something
like refs/remotes/git-svn/HEAD as it's redundant for Subversion
where there's zero distinction between branches and directories.

Run git-svn rebuild --upgrade to upgrade your repository to use
the new head.  git-svn-HEAD must be manually deleted for safety
reasons.

Side note: if you ever (and I hope you never) want to run
git-update-refs on a 'remotes/' ref, make sure you have the
'refs/' prefix as you don't want to be clobbering your
'remotes/' in $GIT_DIR (where remote URLs are stored).
