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.

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...

'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.

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.

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.

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

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.

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).

None of these were really show-stoppers (or even triggered)
on most of the trees I've tracked.
* Node change prevention for identically named nodes. This is
a limitation of SVN, but we find the error and exit before
it's passed to SVN so we don't dirty our working tree when our
commit fails. git-svn will exit with an error code 1 if any
of the following conditions are found:
1. a directory is removed and a file of the same name of the
removed directory is created
1a. a file has its parent directory removed and the file is
takes the name of the removed parent directory::
baz/zzz => baz
2. a file is removed and a directory of the same name of the
removed file is created.
2a. a file is moved into a deeper directory that shares the
previous name of the file::
dir/$file => dir/file/$file
Since SVN cannot handle these cases, the user will have to
manually split the commit into several parts.
* --rmdir now handles nested/deep removals. If dir/a/b/c/d/e/file
is removed, and everything else is in the dir/ hierarchy is
otherwise empty, then dir/ will be deleted when file is deleted
from svn and --rmdir specified.
* Always assert that we have written the tree we want to write
on commits. This helped me find several bugs in the symlink
handling code (which as been fixed).
* Several symlink handling fixes. We now refuse to set
permissions on symlinks. We also always unlink a file
if we're going to overwrite it.
* Apply changes in a pre-determined order, so we always have
rename from locations handy before we delete them.

XML::Simple was originally required back when I made svn-arch-mirror
because I needed to explictly track renames with Arch. Then I carried
it over to git-svn because I was afraid somebody could commit an svn
log message that could throw off a non-XML log parser. Then I noticed
the <n> lines column in the header. So, no more XML :)

We run svn log against a URL without a working copy for the first fetch,
so we end up a log that's sorted from highest to lowest. That's bad, we
always want lowest to highest. Just default to --revision 0:HEAD now if
-r isn't specified for the first fetch.
Also sort the revisions after we get them just in case somebody
accidentally reverses the argument to --revision for whatever reason.
