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));
integrate-txdelta-caching causes a test failure:
