42d328701d git-svn: make the $GIT_DIR/svn/*/revs directory obsolete
This is a very intrusive change, so I've beefed up the tests
significantly.  Added 'full-test' a target to the Makefile,
to test different possible configurations.  This is intended
for maintainers only.  Users should only be concerned with
'test' succeeding.

We now have a very simple custom database format for handling
mapping of svn revisions => git commits.  Of course, we're
not really using it yet, either.

Also disabled automatic branch-finding on new trees for now.
It's too easily broken.  revisions_eq() function should be
helpful for branch detection.

Also removed an extra assertion in fetch_cmd() that wasn't
correctly done.  This bug was found by full-test.

a5e0cedc0a git-svn: add support for Perl SVN::* libraries
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.

79bb8d88fc git-svn: add 'log' command, a facsimile of basic `svn log'
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'

9d55b41aad git-svn: add some functionality to better support branches in svn
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).

dc5869c00d git-svn: add --repack and --repack-flags= options
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.

This should make -B/--branch-all-ref faster and usable on a

We use topological order now for calling git-rev-list, and any

4a393f2b53 git-svn: eol_cp corner-case fixes
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.

8a97e36888 git-svn: fix handling of filenames with embedded '@'
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
