[PATCH/RFC v2 0/9] Subversion dump parsing library

Hi gitsters,

Ram last sent this series a couple of weeks ago[1], and it was merged to pu then as rr/svn-export. Here’s another iteration of the same for discussion, now including David Barr’s program that demonstrates the functionality.

Patch 1 is not so closely related; it just modifies parse_date_toffset() to keep me a little saner while using it.

Patches 2-8 are very similar to the versions Ram sent. I expanded the commit messages, took the latest code from git://github.com/barrbrain/svn-dump-fast-export where possible, and added a simple example build system so one can see the result of compiling with

 make vcs-svn/lib.a

Probably more interesting is what the patches do not do:

 - they do not include any tests

 - they do not remove the persistent object pool functionality.
   If you try this code out, be sure to remove all the .bin
   files from the current directory after each run.

 - they are not guaranteed to have fewer bugs than the version
   Ram sent.  In fact, the opposite is more likely, since the
   code is only lightly tested

You can try it out with

 ; cd contrib/svn-fe
 ; wget http://github.com/barrbrain/svn-dump-fast-export/raw/master/test.dump
 ; make svn-fe
 ; ./svn-fe <test.dump

or

 ; make svn-fe.1
 ; man ./svn-fe.1

and go from there.

Any feedback is appreciated, especially on how to make this fit better with git. I would be particularly interested in making vcs-svn/lib.a self-sufficient --- that is, would there be a simple way to pull out the required code from date.c?
