When traversing trees with an index, the current index pointer
(o->cache_bottom) occasionally has to be temporarily advanced forwards to
match the traversal order of the tree, which is not the same as the sort
order of the index. The existing algorithm that did this (introduced in
730f72840c) would get "stuck" when the
cache_bottom was popped and then repeatedly check the same index entries
over and over. This represents a serious performance regression for
large repositories compared to the old "broken" traversal order.
This commit makes a simple change to mitigate this. Whenever
find_cache_pos sees that the current pos is also the cache_bottom, and
it has already been unpacked, it advances the cache_bottom as well as
the current pos. This prevents the above "sticking" behavior without
dramatically changing the algorithm.
In addition, this commit moves the unpacked check above the
ce_in_traverse_path() check. The simple bitmask check is cheaper, and
in the case described above will be firing quite a bit to advance the
cache_bottom after a tree pop.
This yields considerable performance improvements for large trees.
The following are the number of function calls for "git diff HEAD" on
the Linux kernel tree, with 33,307 files:
Symbol Calls Before Calls After
------------------- ------------ -----------
unpack_callback 35,332 35,332
find_cache_pos 37,357 37,357
ce_in_traverse_path 4,979,473 37,357
do_compare_entry 6,828,181 251,925
df_name_compare 6,828,181 251,925
And on a repository of 187,456 files:
Symbol Calls Before Calls After
------------------- ------------ -----------
unpack_callback 197,958 197,958
find_cache_pos 208,460 208,460
ce_in_traverse_path 37,308,336 208,460
do_compare_entry 156,950,469 2,690,626
df_name_compare 156,950,469 2,690,626
On the latter repository, user time for "git diff HEAD" was reduced from
5.58 to 0.42 seconds. This is compared to 0.30 seconds before the
traversal order fix was implemented.

svn:// servers are more picky regarding redundant slashes
than file:// and http(s)://-backed respositories. Since
the last commit, we avoid putting unnecessary slashes in

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.
