Apparently using the Storable module during global destruction is
unsafe - there is a bug which can cause segmentation faults:
http://rt.cpan.org/Public/Bug/Display.html?id=36087http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482355
The persistent memoization support introduced in commit 8bff7c538
relied on global destruction to write cached data, which was leading
to segfaults in some Perl configurations. Calling Memoize::unmemoize
in the END block forces the cache writeout to be performed earlier,
thus avoiding the bug.

The following command
git svn clone \
-r9500:10006 \
svn://svn.debian.org/svn/pkg-games/packages \
--trunk=/trunk/freedoom \
--branches=/branches/freedoom \
--tags=/tags/freedoom \
freedoom.git.2009091
produces strange results:
With v1.6.3.3 (and perhaps earlier versions), this would fetch up to
and including r9978 (the last revision of the no_iwad_alternatives
branch before it was deleted), check it out, and prematurely declare
success, leaving out some commits to the trunk (r9984, r9985, r10006)
from after the branch was merged.
With v1.6.5-rc0~74 (svn: allow branches outside of refs/remotes,
2009-08-11) and later, this fetches up to and including r9978 and then
attempts a post-fetch checkout and fails.
r9978 = 25f0920175c395f0f22f54ae7a2318147f745274
(refs/remotes/no_iwad_alternatives)
fatal: refs/remotes/trunk: not a valid SHA1
update-ref refs/heads/master refs/remotes/trunk: command returned error: 128
Checking .git/config reveals
fetch = packages//trunk/freedoom:refs/remotes/trunk
And with both 1.6.3.3 and 1.7.1, using --trunk=trunk/freedom without
the leading slash (/) works fine.
Moral: git-svn needs to scrub an initial / from $_trunk and related
arguments it receives. Make it so.

In certain situations it may be necessary to manually remap an svn

o--- [git-svn clone]
/
[origin svn repo]
\
o--- [svnsync clone]
Imagine that only "git-svn clone" and "svnsync clone" are made available
to external users. Furthur, "git-svn clone" contains only trunk, and for
reasons unknown, "svnsync clone" is missing the revision properties that
normally provide the origin svn repo's UUID.
A git user who has cloned the "git-svn clone" repo now wishes to use
git-svn to pull in the missing branches from the "synsync clone" repo.
In order for git-svn to get the history correct for those branches,
it needs to know the origin svn repo's UUID. Hence rewriteUUID.

The old function would have to check all mentioned merge tips, every time

for each listed mergeinfo line. If there are a lot of feature branches
being merged into a trunk, this makes for a very expensive operation for
detecting the new parents on every merge.

When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from. When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.
In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.

git-svn: add (failing) test for SVN 1.5+ merge with intervening commit
This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
properties. The problematic case is when there is some commit on an
unrelated branch after the last commit on the merged-from branch.
When SVN records the mergeinfo property, it records the latest
revision in the whole repository, which, in the problematic case, is
not on the branch it is merging from.
To trigger the git-svn bug, we modify t9151 to include two SVN merges,
the second of which has an intervening commit. The SVN dump was
generated using SVN 1.6.6 (on Debian squeeze amd64).
