Upgrade! CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP. -------------------------------------------------------------------------------- +================================================================================ +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! +Salvatore + +antirez in commit 0a45fbc: + Ability of slave to announce arbitrary ip/port to master. + 6 files changed, 129 insertions(+), 17 deletions(-) + +antirez in commit c3982c0: + redis-benchmark: new option to show server errors on stdout. + 1 file changed, 17 insertions(+), 1 deletion(-) + +antirez in commit fdafe23: + Multiple GEORADIUS bugs fixed. + 6 files changed, 177 insertions(+), 21 deletions(-) + +antirez in commit a1bfe22: + Replication: when possible start RDB saving ASAP. + 1 file changed, 8 insertions(+), 2 deletions(-) + +antirez in commit 7ca69af: + Sentinel: new test unit 07 that tests master down conditions. + 1 file changed, 68 insertions(+) + +antirez in commit 5b5e652: + Sentinel: check Slave INFO state more often when disconnected. + 2 files changed, 10 insertions(+), 3 deletions(-) + +antirez in commit 21cffc2: + Avoid simultaneous RDB and AOF child process. + 4 files changed, 51 insertions(+), 8 deletions(-) + +antirez in commit 017378e: + Replication: start BGSAVE for replication always in replicationCron(). + 1 file changed, 15 insertions(+), 12 deletions(-) + +antirez in commit 940be9a: + Regression test for issue #3333. + 1 file changed, 6 insertions(+) + +antirez in commit 21736b4: + getLongLongFromObject: use string2ll() instead of strict_strtoll(). + 1 file changed, 1 insertion(+), 6 deletions(-) + +antirez in commit 0b748e9: + redis-cli: check SELECT reply type just in state updated. + 1 file changed, 1 insertion(+), 1 deletion(-) + +sskorgal in commit 1158386: + Fix for redis_cli printing default DB when select command fails. + 1 file changed, 1 insertion(+), 1 deletion(-) + +antirez in commit 026f9fc: + Sentinel: fix cross-master Sentinel address update. + 1 file changed, 9 insertions(+), 2 deletions(-) + +antirez in commit 11523b3: + CONFIG GET is now no longer case sensitive. + 1 file changed, 12 insertions(+), 12 deletions(-) + +antirez in commit f5a7f4f: + Fix test for new RDB checksum failure message. + 1 file changed, 1 insertion(+), 1 deletion(-) + +antirez in commit 4c6ff74: + Make tcp-keepalive default to 300 in internal conf. + 1 file changed, 1 insertion(+), 1 deletion(-) + +antirez in commit 27dbec2: + In Redis RDB check: more details in error reportings. + 1 file changed, 24 insertions(+), 13 deletions(-) + +antirez in commit 41f3004: + In Redis RDB check: log decompression errors. + 2 files changed, 23 insertions(+), 2 deletions(-) + +antirez in commit 278fe3e: + In Redis RDB check: log object type on error. + 1 file changed, 27 insertions(+), 2 deletions(-) + +antirez in commit a117dfa: + Added a trivial program to randomly corrupt RDB files in /utils. + 1 file changed, 44 insertions(+) + +antirez in commit f5110c3: + In Redis RDB check: minor output message changes. + 1 file changed, 4 insertions(+), 1 deletion(-) + +antirez in commit 35b18bf: + In Redis RDB check: better error reporting. + 4 files changed, 71 insertions(+), 14 deletions(-) + +antirez in commit f578f08: + In Redis RDB check: initial POC. + 2 files changed, 189 insertions(+), 647 deletions(-) + +tielei in commit 7f1e1ca: + A string with 21 chars is not representable as a 64-bit integer. + 1 file changed, 2 insertions(+), 2 deletions(-) + +antirez in commit 7a3a595: + Test: new randomized stress tester for #3343 alike bugs. + 1 file changed, 27 insertions(+), 2 deletions(-) + +antirez in commit c75ca10: + Stress tester WIP. + 1 file changed, 3 insertions(+) + +antirez in commit 2c3fcf8: + Regression test for issue #3343 exact min crash sequence. + 1 file changed, 16 insertions(+) + +antirez in commit 7041967: + Fix quicklistReplaceAtIndex() by updating the quicklist ziplist size. + 1 file changed, 1 insertion(+) ================================================================================ Redis 3.2.1 Released Fri Jun 17 15:01:56 CEST 2016 diff --git a/src/version.h b/src/version.h index 16a0038e6..c26d48a00 100644 --- a/src/version.h +++ b/src/version.h @@ -1 +1 @@ -#define REDIS_VERSION "3.2.1" +#define REDIS_VERSION "3.2.2" |
