Changes in upstream_hash 0.3:
*) Change: Hashing and failover are compatible with PECL Memcache
(based on
CRC-32).
*) Change: “hash_method” directive removed.
Note that the hashing algorithm is incompatible with old versions of
upstream_hash. I thought that the previous “crc32” algorithm was PECL
Memcache/
libmemcache compatible, but that turned out not to be the case. Now it
really
is compatible (and the new test suite proves it!).
I removed the old “simple” hash method (as well as the hash_method
directive)
because it offers no benefits or compatibility compared with the new
default
hash method.
