When using "git svn rebase" to update my doxygen repository, it continually fails at some random update (example below).  This appears to be a known bug with subversion (since version 1.5) and serf (http://subversion.tigris.org/issues/show_bug.cgi?id=2932).  The update runs fine with USE=webdav-neon (the default).

Comment 1 Robin Johnson archtester Gentoo Infrastructure gentoo-dev Security 2012-03-13 21:32:19 UTC
Did you start your repo with a different SVN webdav backend?
You must keep the same backend consistently.

Beyond that, compile SVN with debug, and ensure SVN_I_LIKE_LATENCY_SO_IGNORE_HTTPV2="yes" is in your environment, and try to actually get some debug output from SVN.

I'm not sure the actual upstream bug you link is the same issue, and you're not going to convince either me or upstream that, unless you show that the raw SVN output being fed to Git doesn't match between Neon & Serf.

You're going to have to get a lot more debug info, or a solid way to reproduce the problem, starting from an empty directory.
Comment 2 Erik Zeek 2012-03-15 13:31:46 UTC
I rebuilt subversion with debug, webdav-neon, and webdav-serf and testing with a clone into a new directory.

If I select the neon RA module (http-library = neon in the server config file), it works fine (a clone into a new directory succeeds).

If I select the serf RA module (http-library = serf in the server config file), it fails.  Again cloning into a new directory.  It's also MUCH slower.  SVN_I_LIKE_LATENCY_SO_IGNORE_HTTPV2 had no effect.

I'm unsure how to get more debugging information.  There is a temp file created, but there were no obvious differences between the two back ends (and it was reaped by perl anyway).  Do you know how to get more out of svn or git-svn?  (My google-fu seens to be failing me.)

The commands I'm using are:
After changing to neon:
git svn clone -s https://doxygen.svn.sourceforge.net/svnroot/doxygen doxygen-neon
After changing to serf:
git svn clone -s https://doxygen.svn.sourceforge.net/svnroot/doxygen doxygen-serf

Neither destination directory existed before cloning.

An example of the temp file:
# cat ~/local/tmp/svn-u5Xy8c 
<S:update-report
   xmlns:S="svn:">
<S:src-path>/svnroot/doxygen</S:src-path>
<S:target-revision>22</S:target-revision>
<S:update-target>trunk</S:update-target>
<S:depth>infinity</S:depth>
<S:entry
   depth="infinity"
   rev="21"></S:entry>
</S:update-report>
