Several points to consider:

  • We should revisit both guides and API docs.
  • The task requires some level of Python understanding, reading throught the code and tests and manual testing.
  • The docs should look nice on readthedocs.

One more crucial point: application developer's journey is incomprehensible. What's the life cycle? What should I call explicitly and what is internal? How should I process requests and its errors in code? Even tests are not useful due to assertSequenceEqual.

Using ``**kwargs`` with ``kwargs.get`` seems like an old-style way to
force argument to be a named one. It is seems like a bad practice and
makes it harder to make a readable documentation.

Overview

  This release introduces the support of extention types (decimal, uuid,
  error, datetime, interval) in MessagePack, various IProto features
  support (feature discovery and push protocol) and major infrastructure
  updates (scm version computation, full documentation for external and
  internal API both as code docstrings and readthedocs HTML, deb and RPM
  packages, and everything is processed with CI/CD pipelines).

Breaking changes

  This release should not break any existing behavior.

New features

  - Backport ConnectionPool support for Python 3.6 (PR #245).
  - Support iproto feature discovery (#206).
  - Decimal type support (#203).
  - UUID type support (#202).
  - Support extra information for iproto errors (#232).
  - Error extension type support (#232).
  - Datetime type support and tarantool.Datetime type (#204, PR #252).

    Tarantool datetime objects are decoded to `tarantool.Datetime`
    type. `tarantool.Datetime` may be encoded to Tarantool datetime
    objects.

    You can create `tarantool.Datetime` objects either from
    MessagePack data or by using the same API as in Tarantool:

    ```python
    dt1 = tarantool.Datetime(year=2022, month=8, day=31,
                             hour=18, minute=7, sec=54,
                             nsec=308543321)

    dt2 = tarantool.Datetime(timestamp=1661969274)

    dt3 = tarantool.Datetime(timestamp=1661969274, nsec=308543321)
    ```

    `tarantool.Datetime` exposes `year`, `month`, `day`, `hour`,
    `minute`, `sec`, `nsec`, `timestamp` and `value` (integer epoch time
    with nanoseconds precision) properties if you need to convert
    `tarantool.Datetime` to any other kind of datetime object:

    ```python
    pdt = pandas.Timestamp(year=dt.year, month=dt.month, day=dt.day,
                           hour=dt.hour, minute=dt.minute, second=dt.sec,
                           microsecond=(dt.nsec // 1000),
                           nanosecond=(dt.nsec % 1000))
    ```

    Use `tzoffset` parameter to set up offset timezone:

    ```python
    dt = tarantool.Datetime(year=2022, month=8, day=31,
                            hour=18, minute=7, sec=54,
                            nsec=308543321, tzoffset=180)
    ```

    You may use `tzoffset` property to get timezone offset of a datetime
    object.

    Use `tz` parameter to set up timezone name:

    ```python
    dt = tarantool.Datetime(year=2022, month=8, day=31,
                            hour=18, minute=7, sec=54,
                            nsec=308543321, tz='Europe/Moscow')
    ```

    If both `tz` and `tzoffset` is specified, `tz` is used.

    You may use `tz` property to get timezone name of a datetime object.

    `timestamp_since_utc_epoch` is a parameter to set timestamp
    convertion behavior for timezone-aware datetimes.

    If ``False`` (default), behaves similar to Tarantool `datetime.new()`:

    ```python
    >>> dt = tarantool.Datetime(timestamp=1640995200, timestamp_since_utc_epoch=False)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00'), tz: ""
    >>> dt.timestamp
    1640995200.0
    >>> dt = tarantool.Datetime(timestamp=1640995200, tz='Europe/Moscow',
    ...                         timestamp_since_utc_epoch=False)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00+0300', tz='Europe/Moscow'), tz: "Europe/Moscow"
    >>> dt.timestamp
    1640984400.0
    ```

    Thus, if ``False``, datetime is computed from timestamp
    since epoch and then timezone is applied without any
    convertion. In that case, `dt.timestamp` won't be equal to
    initialization `timestamp` for all timezones with non-zero offset.

    If ``True``, behaves similar to `pandas.Timestamp`:

    ```python
    >>> dt = tarantool.Datetime(timestamp=1640995200, timestamp_since_utc_epoch=True)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00'), tz: ""
    >>> dt.timestamp
    1640995200.0
    >>> dt = tarantool.Datetime(timestamp=1640995200, tz='Europe/Moscow',
    ...                         timestamp_since_utc_epoch=True)
    >>> dt
    datetime: Timestamp('2022-01-01 03:00:00+0300', tz='Europe/Moscow'), tz: "Europe/Moscow"
    >>> dt.timestamp
    1640995200.0
    ```

    Thus, if ``True``, datetime is computed in a way that `dt.timestamp`
    will always be equal to initialization `timestamp`.

  - Datetime interval type support and tarantool.Interval type (#229).

    Tarantool datetime interval objects are decoded to
    `tarantool.Interval` type. `tarantool.Interval` may be encoded to
    Tarantool interval objects.

    You can create `tarantool.Interval` objects either from
    MessagePack data or by using the same API as in Tarantool:

    ```python
    di = tarantool.Interval(year=-1, month=2, day=3,
                            hour=4, minute=-5, sec=6,
                            nsec=308543321,
                            adjust=tarantool.IntervalAdjust.NONE)
    ```

    Its attributes (same as in init API) are exposed, so you can
    use them if needed.

  - Datetime interval arithmetic support (#229).

    Valid operations:
    - `tarantool.Datetime` + `tarantool.Interval` = `tarantool.Datetime`
    - `tarantool.Datetime` - `tarantool.Interval` = `tarantool.Datetime`
    - `tarantool.Datetime` - `tarantool.Datetime` = `tarantool.Interval`
    - `tarantool.Interval` + `tarantool.Interval` = `tarantool.Interval`
    - `tarantool.Interval` - `tarantool.Interval` = `tarantool.Interval`

    Since `tarantool.Interval` could contain `month` and `year` fields
    and such operations could be ambiguous, you can use `adjust` field
    to tune the logic. The behavior is the same as in Tarantool, see
    [Interval arithmetic RFC](https://github.com/tarantool/tarantool/wiki/Datetime-Internals#interval-arithmetic).

    - `tarantool.IntervalAdjust.NONE` -- only truncation toward the end
      of month performed (default mode).

      ```python
      >>> dt = tarantool.Datetime(year=2022, month=3, day=31)
      datetime: Timestamp('2022-03-31 00:00:00'), tz: ""
      >>> di = tarantool.Interval(month=1, adjust=tarantool.IntervalAdjust.NONE)
      >>> dt + di
      datetime: Timestamp('2022-04-30 00:00:00'), tz: ""
      ```

    - `tarantool.IntervalAdjust.EXCESS` -- overflow mode, without any
      snap or truncation to the end of month, straight addition of days
      in month, stopping over month boundaries if there is less number
      of days.

      ```python
      >>> dt = tarantool.Datetime(year=2022, month=1, day=31)
      datetime: Timestamp('2022-01-31 00:00:00'), tz: ""
      >>> di = tarantool.Interval(month=1, adjust=tarantool.IntervalAdjust.EXCESS)
      >>> dt + di
      datetime: Timestamp('2022-03-02 00:00:00'), tz: ""
      ```

    - `tarantool.IntervalAdjust.LAST` -- mode when day snaps to the end
      of month, if happens.

      ```python
      >>> dt = tarantool.Datetime(year=2022, month=2, day=28)
      datetime: Timestamp('2022-02-28 00:00:00'), tz: ""
      >>> di = tarantool.Interval(month=1, adjust=tarantool.IntervalAdjust.LAST)
      >>> dt + di
      datetime: Timestamp('2022-03-31 00:00:00'), tz: ""
      ```

  - Full documentation of internal and external API (#67).

    dt3 = tarantool.Datetime(timestamp=1661969274, nsec=308543321)

                           microsecond=(dt.nsec // 1000),
                           nanosecond=(dt.nsec % 1000))
    ```

    Use `tzoffset` parameter to set up offset timezone:

    ```python
    dt = tarantool.Datetime(year=2022, month=8, day=31,
                            hour=18, minute=7, sec=54,
                            nsec=308543321, tzoffset=180)

                            nsec=308543321, tz='Europe/Moscow')
    ```

    >>> dt.timestamp
    1640995200.0
    >>> dt = tarantool.Datetime(timestamp=1640995200, tz='Europe/Moscow',
    ...                         timestamp_since_utc_epoch=False)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00+0300', tz='Europe/Moscow'), tz: "Europe/Moscow"
    >>> dt.timestamp

Overview

  This release introduces the support of extention types (decimal, uuid,
  error, datetime, interval) in MessagePack, various IProto features
  support (feature discovery and push protocol) and major infrastructure
  updates (scm version computation, full documentation for external and
  internal API both as code docstrings and readthedocs HTML, deb and RPM
  packages, and everything is processed with CI/CD pipelines).

Breaking changes

  This release should not break any existing behavior.

New features

  - Backport ConnectionPool support for Python 3.6 (PR #245).
  - Support iproto feature discovery (#206).
  - Decimal type support (#203).
  - UUID type support (#202).
  - Support extra information for iproto errors (#232).
  - Error extension type support (#232).
  - Datetime type support and tarantool.Datetime type (#204, PR #252).

    Tarantool datetime objects are decoded to `tarantool.Datetime`
    type. `tarantool.Datetime` may be encoded to Tarantool datetime
    objects.

    You can create `tarantool.Datetime` objects either from
    MessagePack data or by using the same API as in Tarantool:

    ```python
    dt1 = tarantool.Datetime(year=2022, month=8, day=31,
                             hour=18, minute=7, sec=54,
                             nsec=308543321)

    dt2 = tarantool.Datetime(timestamp=1661969274)

    dt3 = tarantool.Datetime(timestamp=1661969274, nsec=308543321)
    ```

    `tarantool.Datetime` exposes `year`, `month`, `day`, `hour`,
    `minute`, `sec`, `nsec`, `timestamp` and `value` (integer epoch time
    with nanoseconds precision) properties if you need to convert
    `tarantool.Datetime` to any other kind of datetime object:

    ```python
    pdt = pandas.Timestamp(year=dt.year, month=dt.month, day=dt.day,
                           hour=dt.hour, minute=dt.minute, second=dt.sec,
                           microsecond=(dt.nsec // 1000),
                           nanosecond=(dt.nsec % 1000))
    ```

    Use `tzoffset` parameter to set up offset timezone:

    ```python
    dt = tarantool.Datetime(year=2022, month=8, day=31,
                            hour=18, minute=7, sec=54,
                            nsec=308543321, tzoffset=180)
    ```

    You may use `tzoffset` property to get timezone offset of a datetime
    object.

    Use `tz` parameter to set up timezone name:

    ```python
    dt = tarantool.Datetime(year=2022, month=8, day=31,
                            hour=18, minute=7, sec=54,
                            nsec=308543321, tz='Europe/Moscow')
    ```

    If both `tz` and `tzoffset` is specified, `tz` is used.

    You may use `tz` property to get timezone name of a datetime object.

    `timestamp_since_utc_epoch` is a parameter to set timestamp
    convertion behavior for timezone-aware datetimes.

    If ``False`` (default), behaves similar to Tarantool `datetime.new()`:

    ```python
    >>> dt = tarantool.Datetime(timestamp=1640995200, timestamp_since_utc_epoch=False)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00'), tz: ""
    >>> dt.timestamp
    1640995200.0
    >>> dt = tarantool.Datetime(timestamp=1640995200, tz='Europe/Moscow',
    ...                         timestamp_since_utc_epoch=False)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00+0300', tz='Europe/Moscow'), tz: "Europe/Moscow"
    >>> dt.timestamp
    1640984400.0
    ```

    Thus, if ``False``, datetime is computed from timestamp
    since epoch and then timezone is applied without any
    convertion. In that case, `dt.timestamp` won't be equal to
    initialization `timestamp` for all timezones with non-zero offset.

    If ``True``, behaves similar to `pandas.Timestamp`:

    ```python
    >>> dt = tarantool.Datetime(timestamp=1640995200, timestamp_since_utc_epoch=True)
    >>> dt
    datetime: Timestamp('2022-01-01 00:00:00'), tz: ""
    >>> dt.timestamp
    1640995200.0
    >>> dt = tarantool.Datetime(timestamp=1640995200, tz='Europe/Moscow',
    ...                         timestamp_since_utc_epoch=True)
    >>> dt
    datetime: Timestamp('2022-01-01 03:00:00+0300', tz='Europe/Moscow'), tz: "Europe/Moscow"
    >>> dt.timestamp
    1640995200.0
    ```

    Thus, if ``True``, datetime is computed in a way that `dt.timestamp`
    will always be equal to initialization `timestamp`.

  - Datetime interval type support and tarantool.Interval type (#229).

    Tarantool datetime interval objects are decoded to
    `tarantool.Interval` type. `tarantool.Interval` may be encoded to
    Tarantool interval objects.

    You can create `tarantool.Interval` objects either from
    MessagePack data or by using the same API as in Tarantool:

    ```python
    di = tarantool.Interval(year=-1, month=2, day=3,
                            hour=4, minute=-5, sec=6,
                            nsec=308543321,
                            adjust=tarantool.IntervalAdjust.NONE)
    ```

    Its attributes (same as in init API) are exposed, so you can
    use them if needed.

  - Datetime interval arithmetic support (#229).

    Valid operations:
    - `tarantool.Datetime` + `tarantool.Interval` = `tarantool.Datetime`
    - `tarantool.Datetime` - `tarantool.Interval` = `tarantool.Datetime`
    - `tarantool.Datetime` - `tarantool.Datetime` = `tarantool.Interval`
    - `tarantool.Interval` + `tarantool.Interval` = `tarantool.Interval`
    - `tarantool.Interval` - `tarantool.Interval` = `tarantool.Interval`

    Since `tarantool.Interval` could contain `month` and `year` fields
    and such operations could be ambiguous, you can use `adjust` field
    to tune the logic. The behavior is the same as in Tarantool, see
    [Interval arithmetic RFC](https://github.com/tarantool/tarantool/wiki/Datetime-Internals#interval-arithmetic).

    - `tarantool.IntervalAdjust.NONE` -- only truncation toward the end
      of month performed (default mode).

      ```python
      >>> dt = tarantool.Datetime(year=2022, month=3, day=31)
      datetime: Timestamp('2022-03-31 00:00:00'), tz: ""
      >>> di = tarantool.Interval(month=1, adjust=tarantool.IntervalAdjust.NONE)
      >>> dt + di
      datetime: Timestamp('2022-04-30 00:00:00'), tz: ""
      ```

    - `tarantool.IntervalAdjust.EXCESS` -- overflow mode, without any
      snap or truncation to the end of month, straight addition of days
      in month, stopping over month boundaries if there is less number
      of days.

      ```python
      >>> dt = tarantool.Datetime(year=2022, month=1, day=31)
      datetime: Timestamp('2022-01-31 00:00:00'), tz: ""
      >>> di = tarantool.Interval(month=1, adjust=tarantool.IntervalAdjust.EXCESS)
      >>> dt + di
      datetime: Timestamp('2022-03-02 00:00:00'), tz: ""
      ```

    - `tarantool.IntervalAdjust.LAST` -- mode when day snaps to the end
      of month, if happens.

      ```python
      >>> dt = tarantool.Datetime(year=2022, month=2, day=28)
      datetime: Timestamp('2022-02-28 00:00:00'), tz: ""
      >>> di = tarantool.Interval(month=1, adjust=tarantool.IntervalAdjust.LAST)
      >>> dt + di
      datetime: Timestamp('2022-03-31 00:00:00'), tz: ""
      ```
