Hi all,
I've just posted the 2.5 release of spymemcached. See the summary of
changes below.
- Matt
------------------------------------------------------------------------
Release of 2.5
Changes since the 2.4 series:
The main new feature of the 2.5 release is support for SASL auth
to go along with the same feature in the memcached 1.4.3 and later
servers.
There is also a new feature which can be used in conjunction with the
failure cancel mode to close all connections to memcached servers if
there are timeouts against a server. This helps to recover from
situations where a memcached server in the list may hard fail.
Also notable is this commit:
cba26c1 If the String value of the socket address starts with a /,
remove it.
This does affect Ketama hashing, as it was found there could be some
occasional mismatch with libketama. A much larger test was added
and to a pretty large degree, compatibility with libketama's hashing is
assured. Proceed with caution if you'll be running a mixed environment
of 2.5 and pre-2.5 spymemcached clients. To get the old behavior by
default, a custom interface is easily implemented.
Additionally, there have been a number of bug fixes, comment cleanups
some new tests, and some consistency fixes.
Changes since 2.4.2:

New TCP connection timeout feature; if server fails completely, d/c.
