Release 0.11.3

Overview

    This is a bugfix release. Several cases of pagination using select
    with after was fixed or improved. Warning has been added to
    potentially long select and count calls. Storage select errors
    were reworked to be consistent with other calls errors.

Breaking changes

    There are no breaking changes in the release.

New features

    * Optimize `crud.select()` without conditions and with
    `after` (PR #295).

    * A critical log entry containing the current stack traceback is
    created upon potentially long `select` and `count` calls —
    an user can explicitly request a full scan through by passing
    `fullscan=true` to `select` or `count` options table argument
    in which case a log entry will not be created (#276).

Bugfixes

    * Make select error description more informative when merger
    built-in module or tuple-merger external module is used
    in case of disabled/uninit storage (#229).

    * `crud.select()` if a condition is '<=' and it's
    value < `after` (PR #295).

    Previous releases:

    tarantool> crud.select('developers',
             > {{'<=', 'id', 3}}, {first = 10, after = rows[5]}).rows
    ---
    - - [2, 401, 'Sergey', 'Allred', 21]
      - [1, 477, 'Alexey', 'Adams', 20]
    ...

    After this release:

    tarantool> crud.select('developers',

      - [2, 401, 'Sergey', 'Allred', 21]

    ...

    * `crud.select()` filtration by a first condition if the condition
    is '>' or '>=' and it's value > `after` (PR #295).

    Previous releases:

    tarantool> crud.select('developers',
             > {{'>=', 'id', 5}}, {first = 10, after = rows[2]}).rows
    ---
    - - [3, 2804, 'Pavel', 'Adams', 27]

      - [6, 1064, 'Alexey', 'Sidorov', 31]
    ...

    After this release:

    tarantool> crud.select('developers',
             > {{'>=', 'id', 5}}, {first = 10, after = rows[2]}).rows
    ---
      - [5, 1172, 'Dmitry', 'Jacobi', 16]
      - [6, 1064, 'Alexey', 'Sidorov', 31]
    ...

    * `crud.select()` results order with negative `first` (PR #295).
    * `crud.select()` if a condition is '=' or '==' with
    negative `first` (PR #295).

    Suppose we have a non-unique secondary index by the field `age`
    field and a space:

    tarantool> crud.select('developers', nil, {first = 10})
    ---
    - metadata: [{'name': 'id', 'type': 'unsigned'},
        {'name': 'bucket_id', 'type': 'unsigned'},
        {'name': 'name', 'type': 'string'},
        {'name': 'surname', 'type': 'string'},
        {'name': 'age', 'type': 'number'}]
      rows:
      - [1, 477, 'Alexey', 'Adams', 20]
      - [2, 401, 'Sergey', 'Allred', 27]
      - [3, 2804, 'Pavel', 'Adams', 27]
      - [4, 1161, 'Mikhail', 'Liston', 27]
      - [5, 1172, 'Dmitry', 'Jacobi', 27]
      - [6, 1064, 'Alexey', 'Sidorov', 31]
    - null
    ...

    Previous releases:

    tarantool> crud.select('developers',
             > {{'=', 'age', 27}}, {first = -10, after = rows[4]}).rows
    ---
    - []
    ...

    After this release:

    tarantool> crud.select('developers',
             > {{'=', 'age', 27}}, {first = -10, after = rows[4]}).rows
    ---
    - - [2, 401, 'Sergey', 'Allred', 27]
