3.1.0

Date: 2024-04-16
Tag: 3.1.0

Overview

3.1.0 is the first stable version of the 3.1 release
series. It introduces 28 improvements and resolves 2 bugs since
3.0.2.

The "stable" label means that we have all planned features implemented and we
see no high-impact issues. However, if you encounter an issue, feel free to
report it on GitHub.

Compatibility

Tarantool 3.x is backward compatible with Tarantool 2.11.x in the 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 3.x series.

Functionality added or changed

Core

  • Introduced fixed-size numeric field types: uint8, int8, uint16, int16,
    uint32, int32, uint64, int64, float32, float64 (gh-9548).
  • Now it is possible to set IPROTO request handler callbacks by using the new
    Lua module trigger, for example: 
    local trigger = require('trigger')
trigger.set('box.iproto.override.select', 'my_select', my_select_handler)
    The method works before the initial box.cfg{} call. Also, the method allows
    setting multiple handlers for a single request type (gh-8138).
  • box.iproto.override() was switched to the universal trigger registry. As a
    side effect, now this function does not raise an error when a wrong request
    type is passed. All such errors are logged with CRITICAL level (gh-8138).
  • Added a new flag tarantool.build.test_build that shows whether a build
    flag TEST_BUILD is set.
  • Hide redundant fields from box.error.unpack() if
    the box_error_unpack_type_and_code compat option is set to 'new'.
    The default behaviour is 'old' (gh-9101).
  • Sped up the creation of large sparse tuples by up to 3.5x in a synthetic test.
  • Error details are now available as error payload fields (gh-9108).
  • Added the name field to an error object (gh-9875).
  • Added a trigger option to box.schema.func.create. This option allows creating
    persistent triggers (gh-8663).

Lua

  • Now it is possible to add custom payload fields to box.error (gh-9104).
  • Added a message argument to the table constructor of box.error.new
    (gh-9102).
  • Added a prev argument to the table constructor of box.error.new (gh-9103).
  • Now it is possible to access a payload field of an error's cause directly
    from the error (gh-9106).
  • Increased the verbosity of box.errors serialization and added a new
    box_error_serialize_verbose option to compat to retain old behaviour
    (gh-9105).
  • Added autocompletion (including payload fields) to box.error (gh-9107).
  • Added the level argument to box.error and box.error.new to specify
    the stack frame used for setting the error location (gh-9792).
  • Added key validation and comparison functions to the key_def module
    (gh-9863).
  • Added a tnt_election_leader_idle metric to built-in metrics.

Http client

  • Added the http_version option to the request(), post(),
    get() and other request functions from the http.client module (gh-9806).

Config

  • Added new config.etcd options watchers.reconnect_timeout and
    watchers.reconnect_max_attempts (ghe-647).
  • Introduced the sharding.rebalancer_mode option (gh-9657).
  • Introduced the sharding.weight configuration option, which reflects
    the relative amount of data that a replicaset can store (gh-9775).
  • config:info() can now display source metadata from the last successful
    load along with source metadata from the very last load attempt (gh-9780).
  • Introduced the labels configuration option. The labels are maps with
    string keys that are merged to instance level (gh-9809).
  • Added the config:instances() method and the instance option to
    config:get() (gh-9680).
  • Introduced the instance_uri() method for the config module (gh-9842).

Experimental

  • Introduced the experimental.connpool module and the
    connect() function of this module (gh-9842).
  • Introduced the filter() function in the experimental.connpool
    module (gh-9842).
  • Introduced the call() function in the experimental.connpool
    module (gh-9842).
  • Introduced the mode option for the filter() and call() functions
    in the experimental.connpool module (gh-9930).

Bugs fixed

Core

  • Provided old and new tuples in box.error.TUPLE_FOUND (gh-6166).
  • An attempt to execute a DDL, DML, DQL, DCL or TCL query within
    a transactional trigger (on_commit or on_rollback) now fails
    with a specific error (gh-9186, gh-7331).

For the list of other bugs fixed you can refer to the 3.0.2 release notes,
since most of the bugs are backported to the previous version.

Tools

  • tarantoolctl has been removed. Systemd, sysvinit and logrotate
    scripts based on it were also removed. All this functionality is covered by the tt utility.
    tarantoolctl is no longer available in official deb and rpm packages. This change will only
    affect the absence of tarantoolctl in future releases of tarball archives.
    (gh-9443).
  • Added the --human-readable option for the misc.memprof parser to print
    sizes like 1KiB, 234MiB, 2GiB, etc.
    Made the errors from the profilers more user-friendly (gh-9217).
