Redis 3.2.2 Released Thu Jul 28 14:14:54 CEST 2016
================================================================================
Upgrade urgency MODERATE: A Redis server and a Sentinel crash are now fixed.
GEORADIUS errors in reported entries are fixed.
Hi all! Redis 3.2.2 is finally out with non trivial bugfixes and a few new
features. Let's start from the bugs:
1. There was a bug in the List type implementation, able to cause the
crash of the server under certain (non trivial to replicate) circumstances
when the LSET command was used. Now the bug is fixed and a new stress tester
that was able to easily trigger the bug was added to the test suite.
2. Redis Sentinel, when monitoring multiple masters, could crash after
a Sentinel address update event.
3. Redis Sentinel now checks slaves INFO state more often when disconnected.
This is not really a bug fix, but may allow to more easily detect that
a slave is able to fail over its master reducing certain delays.
4. It was possible, under a variety of conditions, that the AOF and RDB children
process could spawn at the same time. This is known to trash disk I/O,
AOF performances, and to ultimately create latency in the Redis server.
Normally Redis avoids to have the two writing children at the same time, but
there were edge cases discovered by Oran Agra (that also co-authored the
fix with me) where the double-fork could happen. In order to fix this bug
non trivial changes to the replication code were operated, however it was
important to back port this fix into 3.2.2 because the bug could lead to
bad latency experiences in certain cases.
5. Many GEORADIUS bugs are now fixed \o/. This started as a failing CI
test. I grepped for more clues and there were a number of random failures
in the points reported by GEORADIUS. The errors were found to be related
to three different bugs (one of these was a bug in the test itself).
It's not a critical bug: the effect is to, sometimes, don't report objects
that are near the radius, but only with specific sets of coordinates
and radius settings. However now the issues are fixed and the error
vectors were added as regression tests.
And now the good news (not that bug fixes are not good...), that is, the
new features!
1. Now slaves support the slave-announce-ip and slave-announce-port options.
Using these features a slave can be reported by the master `INFO` output
and `ROLE` command as having arbitrary IP and port. This allows to have
Sentinel deployments when working with containers or NAT-ed environments
more easily.
2. The RDB check utlity is now part of Redis and uses the same RDB code that
Redis uses in order to load the dataset in memory, so a given version
of Redis is always able to check the RDB it produced... without another
external check tool which is supposed to be taken in sync with the
rdb.c implementation. This in turn also means that the new RDB checking
is able to spot more complex bugs, since it really loads the dataset
instead of just skipping bytes.
About the redis-check-dump utility, now it is also able to show certain
information about the RDB file, like the version that produced it, when
it was produced, and so forth. Example:
./redis-check-rdb dump.rdb
[offset 0] Checking RDB file dump.rdb
[offset 32] AUX FIELD redis-ver = '3.2.2'
[offset 46] AUX FIELD redis-bits = '64'
[offset 58] AUX FIELD ctime = '1469710178'
[offset 73] AUX FIELD used-mem = '1186528'
The ability to check how much memory was used by the instance that produced
the RDB file can be especially useful.
For credits and the full change log, see the list of commits below, that was
modified in order to be a bit less verbose compared to the last releases.
Enjoy!
