This means we no longer have to deal with having bloated SVN
working copies around and we get a nice performance increase as
well because we don't have to exec the SVN binary and start a
new server connection each time.
Of course we have to manually manage memory with SVN::Pool
whenever we can, and hack around cases where SVN just eats
memory despite pools (I blame Perl, too). I would like to
keep memory usage as stable as possible during long fetch/commit
processes since I still use computers with only 256-512M RAM.
commit should always be faster with the SVN library code. The
SVN::Delta interface is leaky (or I'm not using it with pools
correctly), so I'm forking on every commit, but that doesn't
seem to hurt performance too much (at least on normal Unix/Linux
systems where fork() is pretty cheap).
fetch should be faster in most common cases, but probably not all.
fetches will be faster where client/server delta generation is
the bottleneck and not bandwidth. Of course, full-files are
generated server-side via deltas, too. Full files are always
transferred when they're updated, just like git-svnimport and
unlike command-line svn. I'm also hacking around memory leaks
(see comments) here by using some more forks.
I've tested fetch with http://, https://, file://, and svn://
repositories, so we should be reasonably covered in terms of
error handling for fetching.
Of course, we'll keep plain command-line svn compatibility as a
fallback for people running SVN 1.1 (I'm looking into library
support for 1.1.x SVN, too). If you want to force command-line
SVN usage, set GIT_SVN_NO_LIB=1 in your environment.
We also require two simultaneous connections (just like
git-svnimport), but this shouldn't be a problem for most
servers.
Less important commands:
show-ignore is slower because it requires repository
access, but -r/--revision <num> can be specified.
graft-branches may use more memory, but it's a
short-term process and is funky-filename-safe.

This quick feature should make it easy to look up svn log
messages when svn users refer to -r/--revision numbers.
The following features from `svn log' are supported:
--revision=<n>[:<n>] - is supported, non-numeric args are not:
HEAD, NEXT, BASE, PREV, etc ...
-v/--verbose - just maps to --raw (in git log), so
it's completely incompatible with
the --verbose output in svn log
--limit=<n> - is NOT the same as --max-count,
doesn't count merged/excluded commits
--incremental - supported (trivial :P)
New features:
--show-commit - shows the git commit sha1, as well
--oneline - our version of --pretty=oneline
Any other arguments are passed directly to `git log'

New commands:
graft-branches - The most interesting command of the bunch. It
detects branches in SVN via various techniques (currently
regexes and file copies). It can be later extended to handle
svk and other properties people may use to track merges in svk.
Basically, merge tracking is not standardized at all in the SVN
world, and git grafts are perfect for dealing with this
situation.
Existing branch support (via tree matches) is only handled at
fetch time.
The following tow were originally implemented as shell scripts
several months ago, but I just decided to streamline things a
bit and added them to the main script.
multi-init - supports git-svnimport-like command-line syntax for
importing repositories that are layed out as recommended by the
SVN folks. This is a bit more tolerant than the git-svnimport
command-line syntax and doesn't require the user to figure out
where the repository URL ends and where the repository path
begins.
multi-fetch - runs fetch on all known SVN branches we're
tracking. This will NOT discover new branches (unlike
git-svnimport), so multi-init will need to be re-run (it's
idempotent).
Consider these three to be auxilliary commands (like
show-ignore, and rebuild) so their behavior won't receive as
much testing or scrutiny as the core commands (fetch and
commit).

This should help keep disk usage sane for large imports.
--repack takes an optional argument for the interval, it
defaults to 1000 if no argument is specified.
Arguments to --repack-flags are passed directly to git-repack.
No arguments are passed by default.

If we read the maximum size of our buffer into $buf, and the
last character is '\015', there's a chance that the character is
'\012', which means our regex won't work correctly. At the
worst case, this could introduce an extra newline into the code.
We'll now read an extra character if we see '\015' is the last
character in $buf.
We also forgot to recalculate the length of $buf after doing the
newline substitution, causing some files to appeare truncated.
We'll do that now and force byte semantics in length() for good
measure.

svn has trouble parsing files with embedded '@' characters. For
example,
svn propget svn:keywords foo@bar.c
svn: Syntax error parsing revision 'bar.c'
I asked about this on #svn and the workaround suggested was to append
an explicit revision specifier:
svn propget svn:keywords foo@bar.c@BASE
This patch appends '@BASE' to the filename in all calls to 'svn
propget'.

Also changed assert_svn_wc_clean() to only work on the svn

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...

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.
