Release 1.9.0

Release type: stable. Release date: 2018-02-26. Tag: 1.9.0-4-g195d446.

This is the successor of the 1.7.6 stable release. The goal of this release is increased maturity of vinyl and master-master replication, and it contributes a number of features to this cause. Please follow the download instructions at https://tarantool.io/en/download/download.html to download and install a package for your operating system.

Functionality added or changed:

(Security) it is now possible to block/unblock users. (gh-2898).

(Security) new function box.session.euid() to return effective user. Effective user can be different from authenticated user in case of setuid functions or box.session.su. (gh-2994).

(Security) new super role, with superuser access. Grant ‘super’ to guest to disable access control. (gh-3022).

(Security) on_auth trigger is now fired in case of both successful and failed authentication. (gh-3039).

(Replication/recovery) new replication configuration algorithm: if replication doesn’t connect to replication_quorum peers in replication_connect_timeout seconds, the server start continues but the server enters the new orphan status, which is basically read-only, until the replicas connect to each other. (gh-3151 and gh-2958).

(Replication/recovery) after replication connect at startup, the server does not start processing write requests before syncing up syncing up with all connected peers.

(Replication/recovery) it is now possible to explicitly set instance_uuid and replica set uuid as configuration parameters. (gh-2967).

(Replication/recovery) box.once() no longer fails on a read-only replica but waits. (gh-2537).

(Replication/recovery) force_recovery can now skip a corrupted xlog file. (gh-3076).

(Replication/recovery) improved replication monitoring: box.info.replication shows peer ip:port and correct replication lag even for idle peers. (gh-2753 and gh-2689).

(Application server) new before triggers which can be used for conflict resolution in master-master replication. (gh-2993).

(Application server) http client now correctly parses cookies and supports http+unix:// paths. (gh-3040 and gh-2801).

(Application server) fio rock now supports file_exists(), rename() works across filesystems, and read() without arguments reads the whole file. (gh-2924, gh-2751 and gh-2925).

(Application server) fio rock errors now follow Tarantool function call conventions and always return an error message in addition to the error flag.

(Application server) digest rock now supports pbkdf2 password hashing algorithm, useful in PCI/DSS compliant applications. (gh-2874).

(Application server) box.info.memory() provides a high-level overview of server memory usage, including networking, Lua, transaction and index memory. (gh-934).

(Database) it is now possible to add missing tuple fields to an index, which is very useful when adding an index along with the evolution of the database schema. gh-2988).

(Database) lots of improvements in field type support when creating or altering spaces and indexes. (gh-2893, gh-3011 and gh-3008).

(Database) it is now possible to turn on is_nullable property on a field even if the space is not empty, the change is instantaneous. (gh-2973).

(Database) logging has been improved in many respects: individual messages (gh-1972, gh-2743, gh-2900), more logging in cases when it was useful (gh-3096, gh-2871).

(Vinyl storage engine) it is now possible to make a unique vinyl index non-unique without index rebuild. (gh-2449).

(Vinyl storage engine) improved UPDATE, REPLACE and recovery performance in presence of secondary keys. (gh-2289, gh-2875 and gh-3154).

(Vinyl storage engine) space:len() and space:bsize() now work for vinyl (although they are still not exact). (gh-3056).

(Vinyl storage engine) recovery speed has improved in presence of secondary keys. (gh-2099).

(Builds) Alpine Linux support. (gh-3067).
