This is a fork of https://gitorious.org/svn2git/svn2git/ with a patch that fixes a segfault. Quoting the original bug:
Sometimes some revisions are filtered out by authz rules on the server, and when you create a mirror with svnsync, you end up with an empty revision that has no revprops whatsoever. This means svnlog, svndate and svnauthor are all NULL. This used to cause segfaults.
Here's some context: http://svn.haxx.se/users/archive-2013-02/0160.shtml
I tested this on a mirror of svn.zope.org (which is publically available). svn-all-fast-export version 1.0.5 (it calls itself 149d6c6e14a1724c96999328683a9264fc508264) segfaults on r129027; this patch fixes the segfault.
I only just now noticed that https://gitorious.org/svn2git/svn2git/merge_requests/19 appears to be fixing the same bug in almost the same way.
Upstream seemed to be dead: they never reacted to my merge request (or to the older one I missed initially).
Since Gitorious is dying too (GitLab bought it), and since GitLab didn't bother making a shiny simple "Move to GitLab" buttom so I have to do this by hand, I'm pushing this to GitHub.
Hey, I found https://github.com/svn-all-fast-export/svn2git on GitHub, which seems to be the same codebase, so I'll try merging the two.
UPDATE: they merged my pull request yay!
Run qmake && make. You get ./svn-all-fast-export.
