v2.8.2

Compare Source

Version 2.8.2 (2021-07-08)

Data updates

• Updated tzdata version to 2021a. (gh pr #​1128)

Bugfixes

• Fixed a bug in the parser where non-ValueError exceptions would be raised
  during exception handling; this would happen, for example, if an
  IllegalMonthError was raised in dateutil code. Fixed by Mark Bailey.
  (gh issue #​981, pr #​987).
• Fixed the custom repr for dateutil.parser.ParserError, which was not
  defined due to an indentation error. (gh issue #​991, gh pr #​993)
• Fixed a bug that caused b' prefixes to appear in parse_isodate exception
  messages. Reported and fixed by Paul Brown (@​pawl) (gh pr #​1122)
• Make isoparse raise when trying to parse times with inconsistent use of
  : separator. Reported and fixed by @​mariocj89 (gh pr #​1125).
• Fixed tz.gettz() not returning local time when passed an empty string.
  Reported by @​labrys (gh issues #​925, #​926). Fixed by @​ffe4 (gh pr #​1024)

Documentation changes

• Rearranged parser documentation into "Functions", "Classes" and "Warnings and
  Exceptions" categories. (gh issue #​992, pr #​994).
• Updated parser.parse documentation to reflect the switch from
  ValueError to ParserError. (gh issue #​992, pr #​994).
• Fixed methods in the rrule module not being displayed in the docs. (gh pr
  #​1025)
• Changed some relative links in the exercise documentation to refer to the
  document locations in the input tree, rather than the generated HTML files in
  the HTML output tree (which presumably will not exist in non-HTML output
  formats). (gh pr #​1078).

Misc

• Moved test_imports.py, test_internals.py and test_utils.py to
  pytest. Reported and fixed by @​jpurviance (gh pr #​978)
• Added project_urls for documentation and source. Patch by @​andriyor (gh pr
  #​975).
• Simplified handling of bytes and bytearray in _parser._timelex. Reported
  and fixed by @​frenzymadness (gh issue #​1060).
• Changed the tests against the upstream tz database to always generate fat
  binaries, since until GH-590 and GH-1059 are resolved, "slim" zic binaries
  will cause problems in many zones, causing the tests to fail. This also
  updates zoneinfo.rebuild to always generate fat binaries. (gh pr #​1076).
• Moved sdist and wheel generation to use python-build. Reported and fixed by
  @​mariocj89 (gh pr #​1133).

v2.8.1

Compare Source

Version 2.8.1 (2019-11-03)

Data updates

• Updated tzdata version to 2019c.

Bugfixes

• Fixed a race condition in the tzoffset and tzstr "strong"
  caches on Python 2.7. Reported by @​kainjow (gh issue #​901).
• Parsing errors will now raise ParserError, a subclass of
  ValueError, which has a nicer string representation. Patch by
  @​gfyoung (gh pr #​881).
• parser.parse will now raise TypeError when tzinfos is passed a
  type that cannot be interpreted as a time zone. Prior to this
  change, it would raise an UnboundLocalError instead. Patch by
  @​jbrockmendel (gh pr #​891).
• Changed error message raised when when passing a bytes object as
  the time zone name to gettz in Python 3. Reported and fixed by
  @​labrys () (gh issue #​927, gh pr #​935).
• Changed compatibility logic to support a potential Python 4.0
  release. Patch by Hugo van Kemenade (gh pr #​950).
• Updated many modules to use tz.UTC in favor of tz.tzutc()
  internally, to avoid an unnecessary function call. (gh pr #​910).
• Fixed issue where dateutil.tz was using a backported version of
  contextlib.nullcontext even in Python 3.7 due to a malformed
  import statement. (gh pr #​963).

Tests

• Switched from using assertWarns to using pytest.warns in the test
  suite. (gh pr #​969).

  explicitly specified as an error in the warnings filter. (gh pr
  #​966)
• Fixed issue where test_tzlocal_offset_equal would fail in certain
  environments (such as FreeBSD) due to an invalid assumption about
  what time zone names are provided. Reported and fixed by Kubilay
  Kocak (gh issue #​918, pr #​928).
• Fixed a minor bug in test_isoparser related to bytes/str
  handling. Fixed by @​fhuang5 (gh issue #​776, gh pr #​879).
• Explicitly listed all markers used in the pytest configuration. (gh
  pr #​915)
• Extensive improvements to the parser test suite, including the
  adoption of pytest-style tests and the addition of parametrization
  of several test cases. Patches by @​jbrockmendel (gh prs #​735,
  #​890, #​892, #​894).
• Added tests for tzinfos input types. Patch by @​jbrockmendel (gh pr
  #​891).

  forbidden. Patch by @​shadchin (gh pr #​893).
• Pinned all test dependencies on Python 3.3. (gh prs #​934, #​962)

Documentation changes

• Fixed many misspellings, typos and styling errors in the comments
  and documentation. Patch by Hugo van Kemenade (gh pr #​952).

Misc

• Added Python 3.8 to the trove classifiers. (gh pr #​970)
• Moved as many keys from setup.py to setup.cfg as possible. Fixed
  by @​FakeNameSE, @​aquinlan82, @​jachen20, and @​gurgenz221 (gh
  issue #​871, gh pr #​880).
• Reorganized parser methods by functionality. Patch by
  @​jbrockmendel (gh pr #​882).
• Switched release.py over to using pep517.build for creating
  releases, rather than direct invocations of setup.py. Fixed by
  @​smeng10 (gh issue #​869, gh pr #​875).
• Added a "build" environment into the tox configuration, to handle
  dependency management when making releases. Fixed by @​smeng10 (gh
  issue #​870,r gh pr #​876).
• GH #​916, GH #​971

• Switched test suite to using pytest (gh pr #​495)
• Switched CI over to use tox. Fixed by @​gaborbernat (gh pr #​549)
