Tarantool 2.4.2

Release: v. 2.4.2 Date: 2020-07-17 Tag: 2.4.2-1-g3f00d29

2.4.2 is the first stable version of the 2.4 release series. The label stable means we have all planned features implemented and we see no high-impact issues.

This release resolves roughly 32 issues since the latest beta version. There may be bugs in less common areas, please feel free to file an issue at GitHub.

Tarantool 2.x is backward compatible with Tarantool 1.10.x in binary data layout, client-server protocol and replication protocol.

Please upgrade using the box.schema.upgrade() procedure to unlock all the new features of the 2.x series.

  • box.session.push() parameter sync is deprecated. A warning is printed when the sync is used, but it still works. It is removed in the next version (gh-4689).

  • Don’t start ‘example’ instance after installing Tarantool (gh-4507).

    Before this release tarantool package for Debian and Ubuntu automatically enable and start ‘example’ instance, which listens on the TCP port 3301. Starting from this release the instance file is installed to /etc/tarantool/instances.available/example.lua, but is not enabled by default and not started anymore. One may perform the following actions to enable and start it:

    ln -s /etc/tarantool/instances.available/example.lua \
    systemctl start tarantool@example

    Existing configuration will not be updated automatically at package update, so manual actions are required to stop and disable the instance (if it is not needed, of course):

    systemctl stop tarantool@example
    rm /etc/tarantool/instances.enabled/example.lua

  • Fixed crash due to triggered dump process during secondary index creation (gh-5042).
  • Fixed crash/deadlock (depending on build type) during dump process scheduling and concurrent DDL operation (gh-4821).
  • Fixed crash during read of prepared but not committed statement (gh-3395).
  • Fixed squashing set and arithmetic upsert operations (gh-5106).
  • Create missing folders for vinyl spaces and indexes if needed to avoid confusing fails of tarantool started from backup (gh-5090).
  • Fixed crash during squash of many (more than 4000) upserts modifying the same key (gh-4957).
