[2.7.3] - 2021-10-27

Changed

• Disabled role's validate_config is not called during config validation.

• Update @tarantool.io/ui-kit and frontend-core dependencies to support the new design style.
  

[2.7.2] - 2021-10-08

Added

• 'Make all instances writeable' configuration field can be hidden via frontend-core's set_variable feature or at runtime.

• New get_issues callback in role API to collect user-defined issues. The issues are gathered from the enabled roles only (which are present in service-registry).

• Allow disabling built-in HTTP "admin" user:

  • by specifying auth_builtin_admin_enabled: false in the instances.yml;
  • using TARANTOOL_AUTH_BUILTIN_ADMIN_ENABLED=false environment variable;
  • permanently in init.lua:

-- init.lua

require('cartridge.auth-backend').set_builtin_admin_enabled(false)
cartridge.cfg({
    auth_backend_name = 'cartridge.auth-backend',
    ...
})

Changed

• Make built-in HTTP "admin" user a part of default auth backend. Custom backends are free of it now.

Fixed

• Eliminate unnecessary transactions after the restart before the replication sync. This reduces the chance the hardware restart leads to WAL corruption (#1546).

• Fix net.box clients compatibility with future tarantool 2.10 versions.

• Fix vshard rebalancer broken by roles reload.

[2.7.1] - 2021-08-10

Fixed

• Update errors dependency to 2.2.1 (Fix compatibility with Tarantool 2.9).

[2.7.0] - 2021-08-10

Added

• New suggestion to restart replication. Whenever the replication isn't running and the reason isn't in the dead upstream, Cartridge will show the corresponding banner in WebUI.
  

• More server details in WebUI: membership, vshard-router, and vshard-storage.

• Roles are stopped with the on_shutdown trigger where it's supported (in Tarantool 2.8+).

• New cartridge.cfg options:

  • webui_prefix (default: "") allows to modify WebUI routes.
  • webui_enforce_root_redirect (default: true) manage redirection.

  To sum up, now they look as follows:

  • <PREFIX>/admin/;
  • <PREFIX>/admin/api;
  • <PREFIX>/admin/config;
  • <PREFIX>/admin/cluster/*;
  • <PREFIX>/static/*;
  • <PREFIX>/login;
  • <PREFIX>/logout;
  • / and <PREFIX>/ redirect to /<PREFIX>/admin (if enabled).

• Support rebalancer_max_sending vshard option.

• New validate_config method in GraphQL API.

• Add zone and zone_distances parameters to test helpers.

Changed

• Merge "Schema" and "Code" pages. Also, allow validating all files, not only the schema.yml.

• Allow expelling a leader. Cartridge will appoint a new leader according to the failover priority from the topology.

• Add default pool.map_call timeout 10 seconds.

• Forbid starting an instance absent in instances.yml.

• Update errors dependency to 2.2.0 with a new method errors.netbox_wait_async to wait for netbox.future result.

• Update membership dependency to 2.4.0 (Changelog).

• Update ddl dependency to 1.5.0 which supplements the clusterwide config with an example schema (Changelog).

• Update vshard to 0.1.18 ([Changelog](<https://github.com/tarantool/vshard/releases/tag/0.1.18)).

Fixed

• Leaders replaced during stateful failover can be expelled now.

• Make failover logging more verbose.

• Fix hot-reload for roles that leave gaps in httpd routes.

• Check user e-mail uniqueness when editing.

• Expelled instances are removed from the _cluster space.

• Fix get_enabled_roles to work w/o arguments.

• Don't default to syslog driver unless /dev/log or /var/run/syslog are available.

• Fix inappropriate consistency timeout that led to "Timed out" error during forceful leader promotion.

• Support automatic parsing of Tarantool Enterprise box options audit_log and audit_nonblock.

• Instance won't suspect any members during RecoveringSnapshot and BootstrappingBox.

Enhanced in WebUI

• Allow to blacklist subpages for complex modules.

• Fix notifications displaying. Close it by clicking anywhere. Keep it open while the mouse is over.

• Various styles enhancements.
