List of integration branches:
-----------------------------
integrate-is-cachable
- replace the fixed 1MB limit to the cachable full-text
size in FSFS with a cache-specific implementation
integrate-partial-getter
- allows access to sub-structures of cached items
- fixes the O(N^2) performance issue with reports on
large directories
integrate-readline-speedup
- very local change
- significant speedup in parsing any FSFS structure
(e.g. directories) other than full-texts and deltas
integrate-txdelta-caching
- implements caching to the txdelta hunks
- enabled for svnadmin only (speedup of dump / verify)
I'm currently integrating these locally to do some performance related
tests, noticed the following few issues (note that I merged the
partial-getter branch before the is-cachable branch, that way code
ends up meeting the performance branch order):
integrate-partial-getter, in cache-memcache.c, in memcache_get_partial:
mc_key = build_key(cache, key, subpool);
should read:
SVN_ERR(build_key(&mc_key, cache, key, subpool));
This was caused by a change in function signatures on
/trunk last December. For some reason, my compiler
didn't even issue a warning here.
Fixed in r1076552.
Because the code in question is not being used for now
(memcached is only used for full-text caching, if at all),
I will do some manual testing here before the merge.
integrate-txdelta-caching causes a test failure:

That looks like your build is broken.
Did you make clean & autobuild.sh?
What OS are you using? On my LINUX
box, static and dynamic builds work.
