Release 0.11.3

[DifferentialOrange]

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 Fix crud.select() + after behavior problems #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 (Write in log when see select(nil) #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 (Calls to routers and storages when crud-router and crud-storage roles initialization is not finished yet #229).

• crud.select() if a condition is '<=' and it's
  value < after (PR Fix crud.select() + after behavior problems #295).

    - [2, 401, 'Sergey', 'Allred', 21]
    - [1, 477, 'Alexey', 'Adams', 20]
  ...
  

• crud.select() filtration by a first condition if the condition
  is '>' or '>=' and it's value > after (PR Fix crud.select() + after behavior problems #295).

  Previous releases:

  tarantool> crud.select('developers',
           > {{'>=', 'id', 5}}, {first = 10, after = rows[2]}).rows

    - [5, 1172, 'Dmitry', 'Jacobi', 16]
    - [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 Fix crud.select() + after behavior problems #295).

• crud.select() if a condition is '=' or '==' with
  negative first (PR Fix crud.select() + after behavior problems #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
  ...
