-# Cleaning up stale Redis sessions
-
-Since version 6.2, GitLab stores web user sessions as key-value pairs in Redis.
-Prior to GitLab 7.3, user sessions did not automatically expire from Redis. If
-you have been running a large GitLab server (thousands of users) since before
-GitLab 7.3 we recommend cleaning up stale sessions to compact the Redis
-database after you upgrade to GitLab 7.3. You can also perform a cleanup while
-still running GitLab 7.2 or older, but in that case new stale sessions will
-start building up again after you clean up.
-
-In GitLab versions prior to 7.3.0, the session keys in Redis are 16-byte
-hexadecimal values such as '976aa289e2189b17d7ef525a6702ace9'. Starting with
-GitLab 7.3.0, the keys are
-prefixed with 'session:gitlab:', so they would look like
-'session:gitlab:976aa289e2189b17d7ef525a6702ace9'. Below we describe how to
-remove the keys in the old format.
-
-First we define a shell function with the proper Redis connection details.
-
-```
-rcli() {
-  # This example works for Omnibus installations of GitLab 7.3 or newer. For an
-  # installation from source you will have to change the socket path and the
-  # path to redis-cli.
-  sudo /opt/gitlab/embedded/bin/redis-cli -s /var/opt/gitlab/redis/redis.socket "$@"
-}
-
-# test the new shell function; the response should be PONG
-rcli ping
-```
-
-Now we do a search to see if there are any session keys in the old format for
-us to clean up.
-
-```
-# returns the number of old-format session keys in Redis
-rcli keys '*' | grep '^[a-f0-9]\{32\}$' | wc -l
-```
-
-If the number is larger than zero, you can proceed to expire the keys from
-Redis. If the number is zero there is nothing to clean up.
-
-```
-# Tell Redis to expire each matched key after 600 seconds.
-rcli keys '*' | grep '^[a-f0-9]\{32\}$' | awk '{ print "expire", $0, 600 }' | rcli
-# This will print '(integer) 1' for each key that gets expired.
-```
-
-Over the next 15 minutes (10 minutes expiry time plus 5 minutes Redis
-background save interval) your Redis database will be compacted. If you are
-still using GitLab 7.2, users who are not clicking around in GitLab during the
-10 minute expiry window will be signed out of GitLab.
