Bugs fixed

Core

Fixed a bug introduced in Tarantool 2.10.2: log messages could be written to data files thus causing data corruption. The issue was fixed by reverting the fix for gh-4450.
Switched from MT-Unsafe strerror() to MT-Safe strerror_r(). The usage of the unsafe function could result in corrupted error messages.
Fixed a bug when a single JSON update couldn’t insert and update a field of a map or an array in two sequential calls. It would either crash or return an error (gh-7705).

Memtx

Fixed incorrect handling of transaction conflicts in full scans by HASH indexes (gh-7493).
Fixed use after free that could occur in the transaction manager in certain states (gh-7449).
Fixed possible phantom reads with get on TREE indexes containing nullable parts (gh-7685).
Fixed an inconsistency in index:random in the context of transaction management (gh-7670).
Fixed unserializable reads tracked incorrectly after transaction rollbacks (gh-7343).

Replication

Fixed a bug when a fiber committing a synchronous transaction could hang if the instance got a term bump during that or its synchro-queue was fenced in any other way (gh-7253).
Fixed master occasionally deleting xlogs needed by replicas even without a restart (gh-7584).

Raft

Fixed a bug when box.ctl.promote() could hang and bump thousands of terms in a row if called on more than one node at the same time (part of gh-7253).
Fixed a bug when a node with election_mode='voter' could hang in box.ctl.promote() or become a leader (part of gh-7253).
Fixed a bug when a replicaset could be split into parts if a node voted for another instance while having local WAL writes unfinished (part of gh-7253).

Lua

Merger

Fixed use after free that could occur during iteration over merge_source:pairs() or merger:pairs() (gh-7657).

Popen

Fixed a race condition in <popen handle>:signal() on Mac OS 12 and newer (gh-7658).

Box

Fixed a bug when fiber.yield() might break the execution of a shutdown trigger (gh-7434).
Fixed a possible high CPU usage caused by shutdown triggers (gh-6801).

Synchro

Fixed assertions in debug builds and undefined behaviour in release builds when simultaneous elections started or another instance was promoted while an instance was acquiring or releasing the synchro queue (gh-7086).

Uri

Fixed a bug in the URI parser: tarantoolctl could not connect when the host name was skipped (gh-7479).
