da011cb0e7 contrib/svn-fe: fix Makefile
Fixes several problems:
  * include config.mak.uname, config.mak.autogen and config.mak
    in order to use settings for prefix and other such things;
  * link xdiff/lib.a as it is a requirement for libgit.a;
  * fix CFLAGS, LDFLAGS and EXTLIBS for Linux and Mac OS X.

20c4fbf97d svn-fe: conform to pep8
Quite a large change, most of this was whitespace changes, though there
were a few places where I removed a comma or added a few characters.
Should pass through pep8 and pass every test.

cadbf5c7ed svn-fe: allow svnrdump_sim.py to run with Python 3
The changes to allow this script to run with Python 3 are minimal and do
not affect its functionality on the versions of Python 2 that are
already supported (2.4 onwards).

16a7185447 Add a svnrdump-simulator replaying a dump file for testing
To ease testing without depending on a reachable svn server, this
compact python script mimics parts of svnrdumps behaviour.  It
requires the remote url to start with sim://.

Start and end revisions are evaluated.  If the requested revision
doesn't exist, as it is the case with incremental imports, if no new
commit was added, it returns 1 (like svnrdump).

To allow using the same dump file for simulating multiple incremental
imports, the highest revision can be limited by setting the environment
variable SVNRMAX to that value. This simulates the situation where
higher revs don't exist yet.

8e43a1d010 remote-svn: add incremental import
Search for a note attached to the ref to update and read it's
'Revision-number:'-line. Start import from the next svn revision.

If there is no next revision in the svn repo, svnrdump terminates with
a message on stderr an non-zero return value. This looks a little
weird, but there is no other way to know whether there is a new
revision in the svn repo.

On the start of an incremental import, the parent of the first commit
in the fast-import stream is set to the branch name to update. All
following commits specify their parent by a mark number. Previous mark
files are currently not reused.

271fd1fc2a remote-svn, vcs-svn: Enable fetching to private refs
The reference to update by the fast-import stream is hard-coded.  When
fetching from a remote the remote-helper shall update refs in a
private namespace, i.e. a private subdir of refs/.  This namespace is
defined by the 'refspec' capability, that the remote-helper advertises
as a reply to the 'capabilities' command.

Extend svndump and fast-export to allow passing the target ref.
Update svn-fe to be compatible.

7a75e661c5 vcs-svn: implement text-delta handling
Handle input in Subversion's dumpfile format, version 3.  This is the
format produced by "svnrdump dump" and "svnadmin dump --deltas", and
the main difference between v3 dumpfiles and the dumpfiles already
handled is that these can include nodes whose properties and text are
expressed relative to some other node.

To handle such nodes, we find which node the text and properties are
based on, handle its property changes, use the cat-blob command to
request the basis blob from the fast-import backend, use the
svndiff0_apply() helper to apply the text delta on the fly, writing
output to a temporary file, and then measure that postimage file's
length and write its content to the fast-import stream.

The temporary postimage file is shared between delta-using nodes to
avoid some file system overhead.

The svn-fe interface needs to be more complicated to accomodate the
backward flow of information from the fast-import backend to svn-fe.
The backflow fd is not needed when parsing streams without deltas,
though, so existing scripts using svn-fe on v2 dumps should
continue to work.

NEEDSWORK: generalize interface so caller sets the backflow fd, close
temporary file before exiting

41529bbce4 vcs-svn: set up channel to read fast-import cat-blob response
Set up some plumbing: teach the svndump lib to pass a file descriptor
number to the fast_export lib, representing where cat-blob/ls
responses can be read from, and add a get_response_line helper
function to the fast_export lib to read a line from that file.

Unfortunately this means that svn-fe needs file descriptor 3 to be
redirected from somewhere (preferrably the cat-blob stream of a
fast-import backend); otherwise it will fail:

	$ svndump <path> | svn-fe
	fatal: cannot read from file descriptor 3: Bad file descriptor

For the moment, "svn-fe 3</dev/null" works as a workaround but it
will not work for very long.  A fast-import backend that can retrieve
old commits is needed in order to be able to fulfill svn
"Node-copyfrom-rev" requests that refer to revs from a previous run.

712308f29a Update svn-fe manual
The svn-fe example does not litter the working directory with
.bin files any more (hoorah!).

The permissive error handling implies a known bug.  We should
be flagging iffy input and, even if we continue, reporting it
on exit.

21746aa34f SVN dump parser
svndump parses data that is in SVN dumpfile format produced by
`svnadmin dump` with the help of line_buffer and uses repo_tree and
fast_export to emit a git fast-import stream.

Based roughly on com.hydrografix.svndump 0.92 from the SvnToCCase
project at <http://svn2cc.sarovar.org/>, by Stefan Hegny and
others.
