Changelog

1.3.3 (2015-10-02)

• Fixed typo in ABSOLUTELLY_ALL_METHODS name (now ABSOLUTELY_ALL_METHODS). Old name is still there for backwards compatibility.

1.3.2 (2015-09-22)

• Fixed another tricky bug in the generator advising wrappers - result was not returned if only Proceed was yielded.

1.3.1 (2015-09-12)

• Corrected result handling when using Aspects on generators.

1.3.0 (2015-06-06)

• Added messages property to aspectlib.test.LogCapture. Change call to have level name instead of number.

• Fixed a bogus warning from aspectlib.patch_module` when patching methods on old style classes.

1.2.2 (2014-11-25)

• Added support for weakrefs in the __logged__ wrapper from aspectlib.debug.log decorator.

1.2.1 (2014-10-15)

• Don’t raise exceptions from Replay.__exit__ if there would be an error (makes original cause hard to debug).

1.2.0 (2014-06-24)

• Fixed weaving methods that were defined in some baseclass (and not on the target class).

• Fixed wrong qualname beeing used in the Story/Replay recording. Now used the alias given to the weaver instead of whatever is the realname on the current platform.

1.1.1 (2014-06-14)

• Use ASPECTLIB_DEBUG for every logger in aspectlib.

1.1.0 (2014-06-13)

• Added a bind option to aspectlib.Aspect so you can access the cutpoint from the advisor.

• Replaced automatic importing in aspectlib.test.Replay with extraction of context variables (locals and globals from the calling aspectlib.test.Story). Works better than the previous inference of module from AST of the result.

• All the methods on the replay are now properties: aspectlib.test.Story.diff, aspectlib.test.Story.unexpected and aspectlib.test.Story.missing.

• Added aspectlib.test.Story.actual and aspectlib.test.Story.expected.

• Added an ASPECTLIB_DEBUG environment variable option to switch on debug logging in aspectlib’s internals.

1.0.0 (2014-05-03)

• Reworked the internals aspectlib.test.Story to keep call ordering, to allow dependencies and improved the serialization (used in the diffs and the missing/unexpected lists).

0.9.0 (2014-04-16)

• Changed aspectlib.test.record:

  • Renamed history option to calls.

  • Renamed call option to iscalled.

  • Added callback option.

  • Added extended option.

• Changed aspectlib.weave:

  • Allow weaving everything in a module.

  • Allow weaving instances of new-style classes.

• Added aspectlib.test.Story class for capture-replay and stub/mock testing.

0.8.1 (2014-04-01)

• Use simpler import for the py3support.

0.8.0 (2014-03-31)

• Change aspectlib.debug.log to use aspectlib.Aspect and work as expected with coroutines or generators.

• Fixed aspectlib.debug.log to work on Python 3.4.

• Remove the undocumented aspectlib.Yield advice. It was only usable when decorating generators.

0.7.0 (2014-03-28)

• Add support for decorating generators and coroutines in aspectlib.Aspect.

• Made aspectlib raise better exceptions.

0.6.1 (2014-03-22)

• Fix checks inside aspectlib.debug.log that would inadvertently call __bool__/__nonzero.

0.6.0 (2014-03-17)

• Don’t include __getattribute__ in ALL_METHODS - it’s too dangerous dangerous dangerous dangerous dangerous dangerous … ;)

• Do a more reliable check for old-style classes in debug.log

• When weaving a class don’t weave attributes that are callable but are not actually routines (functions, methods etc)

0.5.0 (2014-03-16)

• Changed aspectlib.debug.log:

  • Renamed arguments to call_args.

  • Renamed arguments_repr to call_args_repr.

  • Added call option.

  • Fixed issue with logging from old-style methods (object name was a generic “instance”).

• Fixed issues with weaving some types of builtin methods.

• Allow to apply multiple aspects at the same time.

• Validate string targets before weaving. aspectlib.weave('mod.invalid name', aspect) now gives a clear error (invalid name is not a valid identifier)

• Various documentation improvements and examples.

0.4.1 (2014-03-08)

• Remove junk from 0.4.0’s source distribution.

0.4.0 (2014-03-08)

• Changed aspectlib.weave:

  • Replaced only_methods, skip_methods, skip_magicmethods options with methods.

  • Renamed on_init option to lazy.

  • Added aliases option.

  • Replaced skip_subclasses option with subclasses.

• Fixed weaving methods from a string target.

0.3.1 (2014-03-05)

• ???

0.3.0 (2014-03-05)

• First public release.
