Changelog

3.7.0 (2024-05-02)

  • Drop support for Python 3.7.
  • Upgrade linters and refactor various string formatting and other cleanups.
  • Upgrade Cython to latest release (3.0.10).
  • Linux wheels should be back now.
  • Switched docs theme to furo.

3.6.1 (2023-04-26)

  • Added safe repr support for Decimal objects.

3.6.0 (2023-04-25)

  • Added C extension support for Python 3.11. This may come with up to 10% performance hit (depending on use-case) for all Pythons. Unfortunately some compat shims are now used for getting frame details. This is necessary to be able to work with Python 3.11 and be more future-proof.
  • Added safe repr support for ZoneInfo objects.
  • C extension files are now prebuilt with Cython 3.0b2.
  • Replaced the flake8/isort pre-commit hooks with ruff.
  • Disabled editable wheels (PEP-0662) as they don't include the hunter.pth file. There may be a way to do it but I haven't figured out a way to customize the editable_wheel command without a very brittle solution glued to setuptools' internals.

3.5.1 (2022-09-27)

  • Fixed breakage in hunter-trace when Ctrl-C.

3.5.0 (2022-09-11)

  • Add support for generators and coroutines in the :obj:`hunter.wrap` decorator.
  • Dropped support for Python 3.6.

3.4.3 (2021-12-15)

  • Removed most of the Python 2 support code.
  • Fix some refactoring regression in setup.py and make the 3.4.x series installable only on Python 3.6 and later.
  • Yank 3.4.0, 3.4.1, 3.4.2 releases to avoid install problems on Python 2.7.

3.4.2 (2021-12-15)

  • Fixed CI to properly make win32 wheels.

3.4.1 (2021-12-14)

  • Add support for building a pp37.pp38 tagged wheel (basically an universal wheel installable just for those two PyPy versions).

3.4.0 (2021-12-14)

  • Switched CI to GitHub Actions, this has a couple consequences:
    • Support for Python 2.7 is dropped. You can still install it there but it's not tested anymore and Python 2 specific handling will be removed at some point.
    • Linux wheels are now provided in musllinux and manylinux2014 variants.
  • Extension building is now completely skipped on PyPy.
  • A pure but tagged as platform specific wheel is now provided for PyPy (to have fast installs there as well).

3.3.8 (2021-06-23)

  • Fixed CI problem that publishes same type of wheels two times.

3.3.7 (2021-06-23)

  • Fixed a bug with how stdlib is detected on Windows (at least).

3.3.6 (2021-06-23)

  • Fixed regression from 3.3.4: stdlib filter was broken.
  • Improved the pth file (PYTHONHUNTER environment variable activation) to use a clean eval environment. No bogus variables like line (from the site.py machinery) will be available anymore.
  • Fixed a bug in VarsSnooper that would make it fail in rare situation where a double return event is emitted.

3.3.5 (2021-06-11)

  • Added support for Python 3.10.
  • Added support for time objects and the fold option in safe_repr.
  • 3.3.4 was skipped cause I messed up the CI.

3.3.3 (2021-05-04)

  • Fixed tracer still being active for other threads after it was stopped.

    Python unfortunately only allows removing the trace function for the current thread - now :obj:`~hunter.tracer.Tracer` will uninstall itself if it's marked as stopped.

    This fixes bogus errors that appear when using ipdb with the :class:`hunter.actions.Debugger` action while thread support is enabled (the default).

3.3.2 (2021-03-25)

  • Changed CI to build Python 3.9 wheels. Python 3.5 no longer tested and wheels no longer built to keep things simple.
  • Documentation improvements.

3.3.1 (2020-10-24)

  • Fixed CI/test issues that prevented all of 21 wheels being published.

3.3.0 (2020-10-23)

  • Fixed handling so that :any:`hunter.event.Event.module` is always the "?" string instead of None. Previously it was None when tracing particularly broken code and broke various predicates.
  • Similarly :any:`hunter.event.Event.filename` is now "?" if there's no filename available.
  • Building on the previous changes the actions have simpler code for displaying missing module/filenames.
  • Changed :class:`hunter.actions.CallPrinter` so that trace events for builtin functions are displayed differently. These events appear when using profile mode (eg: trace(profile=True)).
  • Fixed failure that could occur if :any:`hunter.event.Event.module` is an unicode string. Now it's always a regular string. Only applies to Python 2.
  • Fixed argument display when tracing functions with tuple arguments. Closes #88. Only applies to Python 2.
  • Improved error reporting when internal failures occur. Now some details about the triggering event are logged.

3.2.2 (2020-09-04)

  • Fixed oversight over what value is in :any:`hunter.event.Event.builtin`. Now it's always a boolean, and can be used consistently in filters (eg: builtin=True,function='getattr').

3.2.1 (2020-08-18)

3.2.0 (2020-08-16)

3.1.3 (2020-02-02)

  • Improved again the stdlib check to handle certain paths better.

3.1.2 (2019-01-19)

  • Really fixed the <frozen importlib.something stdlib check.

3.1.1 (2019-01-19)

  • Marked all the <frozen importlib.something files as part of stdlib.

3.1.0 (2019-01-19)

3.0.5 (2019-12-06)

  • Really fixed safe_repr so it doesn't cause side-effects (now isinstance/issubclass are avoided - they can cause side-effects in code that abuses descriptors in special attributes/methods).

3.0.4 (2019-10-26)

3.0.3 (2019-10-13)

3.0.2 (2019-10-10)

3.0.1 (2019-06-17)

  • Fixed issue with coloring missing source message (coloring leaked into next line).

3.0.0 (2019-06-17)

2.2.1 (2019-01-19)

  • Fixed a link in changelog.
  • Fixed some issues in the Travis configuration.

2.2.0 (2019-01-19)

  • Added :class:`hunter.predicates.From` predicate for tracing from a specific point. It stop after returning back to the same call depth with a configurable offset.
  • Fixed PYTHONHUNTERCONFIG not working in some situations (config values were resolved at the wrong time).
  • Made tests in CI test the wheel that will eventually be published to PyPI (tox-wheel).
  • Made event.stdlib more reliable: pkg_resources is considered part of stdlib and few more paths will be considered as stdlib.
  • Dumbed down the get_peercred check that is done when attaching with hunter-trace CLI (via hunter.remote.install()). It will be slightly insecure but will work on OSX.
  • Added OSX in the Travis test grid.

2.1.0 (2018-11-17)

  • Made threading_support on by default but output automatic (also, now 1 or 0 allowed).
  • Added pid_alignment and force_pid action options to show a pid prefix.
  • Fixed some bugs around __eq__ in various classes.
  • Dropped Python 3.3 support.
  • Dropped dependency on fields.
  • Actions now repr using a simplified implementation that tries to avoid calling __repr__ on user classes in order to avoid creating side-effects while tracing.
  • Added support for the PYTHONHUNTERCONFIG environment variable (stores defaults and doesn't activate hunter).

2.0.2 (2017-11-24)

  • Fixed indentation in :class:`hunter.actions.CallPrinter` action (shouldn't deindent on exception).
  • Fixed option filtering in Cython Query implementation (filtering on tracer was allowed by mistake).
  • Various fixes to docstrings and docs.

2.0.1 (2017-09-09)

  • Now Py_AddPendingCall is used instead of acquiring the GIL (when using GDB).

2.0.0 (2017-09-02)

1.4.1 (2016-09-24)

  • Fix support for getting sources for Cython module (it was broken on Windows and Python3.5+).

1.4.0 (2016-09-24)

  • Added support for tracing Cython modules (#30). A # cython: linetrace=True stanza or equivalent is required in Cython modules for this to work.

1.3.0 (2016-04-14)

1.2.2 (2016-01-28)

  • Fix broken import. Require fields>=4.0.
  • Simplify a string check in Cython code.

1.2.1 (2016-01-27)

1.2.0 (2016-01-24)

1.1.0 (2016-01-21)

  • Implemented a destructor (__dealloc__) for the Cython tracer.
  • Improved the restoring of the previous tracer in the Cython tracer (use PyEval_SetTrace) directly.
  • Removed tracer as an allowed filtering argument in hunter.Query.
  • Add basic validation (must be callable) for positional arguments and actions passed into hunter.Q. Closes #23.
  • Fixed stdlib checks (wasn't very reliable). Closes #24.

1.0.2 (2016-01-05)

  • Fixed missing import in setup.py.

1.0.1 (2015-12-24)

  • Fix a compile issue with the MSVC compiler (seems it don't like the inline option on the fast_When_call).

1.0.0 (2015-12-24)

  • Implemented fast tracer and query objects in Cython. MAY BE BACKWARDS INCOMPATIBLE

    To force using the old pure-python implementation set the PUREPYTHONHUNTER environment variable to non-empty value.

  • Added filtering operators: contains, startswith, endswith and in. Examples:

    • Q(module_startswith='foo' will match events from foo, foo.bar and foobar.
    • Q(module_startswith=['foo', 'bar'] will match events from foo, foo.bar, foobar, bar, bar.foo and baroo .
    • Q(module_endswith='bar' will match events from foo.bar and foobar.
    • Q(module_contains='ip' will match events from lipsum.
    • Q(module_in=['foo', 'bar'] will match events from foo and bar.
    • Q(module_regex=r"(re|sre.*)\b") will match events from ``re, re.foobar, srefoobar but not from repr.

  • Removed the merge option. Now when you call hunter.trace(...) multiple times only the last one is active. BACKWARDS INCOMPATIBLE

  • Remove the previous_tracer handling. Now when you call hunter.trace(...) the previous tracer (whatever was in sys.gettrace()) is disabled and restored when hunter.stop() is called. BACKWARDS INCOMPATIBLE

  • Fixed CodePrinter to show module name if it fails to get any sources.

0.6.0 (2015-10-10)

  • Added a clear_env_var option on the tracer (disables tracing in subprocess).
  • Added force_colors option on :class:`hunter.actions.VarsPrinter` and :class:`hunter.actions.CodePrinter`.
  • Allowed setting the stream to a file name (option on :class:`hunter.actions.VarsPrinter` and :class:`hunter.actions.CodePrinter`).
  • Bumped up the filename alignment to 40 cols.
  • If not merging then self is not kept as a previous tracer anymore. Closes #16.
  • Fixed handling in VarsPrinter: properly print eval errors and don't try to show anything if there's an AttributeError. Closes #18.
  • Added a stdlib boolean flag (for filtering purposes). Closes #15.
  • Fixed broken frames that have "None" for filename or module (so they can still be treated as strings).
  • Corrected output files in the install_lib command so that pip can uninstall the pth file. This only works when it's installed with pip (sadly, setup.py install/develop and pip install -e will still leave pth garbage on pip uninstall hunter).

0.5.1 (2015-04-15)

0.5.0 (2015-04-06)

0.4.0 (2015-03-29)

  • Disabled colors for Jython. Contributed by Claudiu Popa in #12.
  • Test suite fixes for Windows. Contributed by Claudiu Popa in #11.
  • Added an introduction section in the docs.
  • Implemented a prettier fallback for when no sources are available for that frame.
  • Implemented fixups in cases where you use action classes as a predicates.

0.3.1 (2015-03-29)

  • Forgot to merge some commits ...

0.3.0 (2015-03-29)

  • Added handling for internal repr failures.
  • Fixed issues with displaying code that has non-ascii characters.
  • Implemented better display for call frames so that when a function has decorators the function definition is shown (instead of just the first decorator). See: #8.

0.2.1 (2015-03-28)

0.2.0 (2015-03-27)

0.1.0 (2015-03-22)

  • First release on PyPI.
