Upgrade! CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP. -------------------------------------------------------------------------------- +--[ Redis 3.0.4 ] Release date: 8 Sep 2015 + +Upgrade urgency: HIGH for Redis and Sentinel. However note that in order to + fix certain replication bugs, the replication internals were + modified in a very heavy way. So while this release is + conceptually saner, it may contain regressions. For this + reason, before the release, QA activities were performed by + me (antirez) and Redis Labs and no evident bug was found. + +* [FIX] A number of bugs related to replication PSYNC and the (yet experimental) + diskless replication feature were fixed. The bugs could lead to + inconsistency between masters and slaves. (Salvatore Sanfilippo, Oran + Agra fixed the issue found by Yuval Inbar) +* [FIX] A replication bug in the context of PSYNC partial resynchonization was + found and fixed. This bug happens even when diskless replication is off + in the case different slaves connect at different times while the master + is creating an RDB file, and later a partial resynchronization is + attempted by a slave that connected not as the first one. (Salvatore + Sanfilippo, Oran Agra) +* [FIX] Chained replication and PSYNC interactions leading to potential stale + chained slaves data set, see issue #2694. (Salvatore Sanfilippo fixed + an issue reported by "GeorgeBJ" user at Github) +* [FIX] redis-cli --scan iteration fixed when returned cursor overflows + 32 bit signed integer. (Ofir Luzon, Yuval Inbar) +* [FIX] Senitnel: fixed a bug during the master switch process, where for a + failed conditional check, the new configuration is rewritten, during + a small window of time, in a corrupted way where the master is + also reported to be one of the slaves. This bug is rare to trigger + but apparently it happens in the wild, and the effect is to see + a replication loop where the master will try to replicate with itself. + A detailed explanation of the bug and its effects can be found in + the commit message here: https://github.com/antirez/redis/commit/c20218eb5770b2cafb12bc7092313b8358fedc0a. + The bug was found by Jan-Erik Rediger using a static analyzer and + fixed by Salvatore Sanfilippo. +* [FIX] Sentinel lack of arity checks for certain commands. + (Rogerio Goncalves, Salvatore Sanfilippo) + +* [NEW] Replication internals rewritten in order to be more resistant to bugs. + The replication handshake in the slave side was rewritten as a non + blocking state machine. (Salvatore Sanfilippo, Oran Agra) +* [NEW] New "replication capabilities" feature introduced in order to signal + from the master to the slave what are the features supported, so that + the master can choose the kind of replication to start (diskless or + not) when master and slave are of different versions. (Oran Agra, + Salvatore Sanfilippo) +* [NEW] Log clients details when SLAVEOF command is received.
