Memcached 1.4.4 Release Notes
Date: 2009-11-26 Sat
This is a maintenance release of memcached with a workaround for common client issue as well as a few new stats.
Add partial backwards compatibility for delete with timeout 0
Before version 1.4.0, there was an optional argument to delete that would allow a client to specify that a deleted object should exist in the cache after the deletion occurred such that add operations would fail even though objects did not appear in the cache.
This feature was removed completely in 1.4.0, but a parser bug caused it to slip through. The bug was fixed in 1.4.3. If anyone was attempting to use it legitimately in the 1.4 series, it would simply not work as expected.
The 1.4.4 backwards compatibility change allows specifically the value of 0 (i.e. non-lingering delete), while continuing to reject others. This will satisfy clients that always wish to send a value even when they do not wish the item to linger.
==== auth_enabled_sasl ====
This is a general stat that indicates whether SASL authentication is enabled or not.
==== auth_cmds ====
Indicates the total number of authentication attempts.
==== auth_errors ====
Indicates the number of failed authentication attempts.
