New Features

New stat: reclaimed

This stat reports the number of times an entry was stored using memory from an expired entry.

sasl_pwdb for more simple auth deployments

--enable-sasl-pwdb allows memcached to use it's own password file and verify a plaintext password.

The file is specified with the environment variable MEMCACHED_SASL_PWDB, and is a plain text file with the following syntax:


Please note that you have to specify "mech_list: plain" in your sasl config file for this to work.


   echo "mech_list: plain" > memcached.conf
   echo "myname:mypass" > /tmp/memcached-sasl-db
   export MEMCACHED_SASL_PWDB=/tmp/memcached-sasl-db
   export SASL_CONF_PATH=`pwd`/memcached.conf
   ./memcached -S -v

and you should be able to use your favorite memcached client with sasl support to connect to the server.

(Please note that not all SASL implementations support SASL_CB_GETCONF, so you may have to install the sasl config (memcached.conf) to the systemwide location)
