Changelog

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 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 CallPrinter action (shoudln’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)

• Added the Event.count and Event.calls attributes.
• Added the lt/lte/gt/gte lookups.
• Added convenience aliases for startswith (sw), endswith (ew), contains (has) and regex (rx).
• Added a convenience hunter.wrap decorator to start tracing around a function.
• Added support for remote tracing (with two backends: manhole and GDB) via the hunter-trace bin. Note: Windows is NOT SUPPORTED.
• Changed the default action to CallPrinter. You’ll need to use action=CodePrinter if you want the old output.

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)

• Added Event.thread.
• Added Event.threadid and Event.threadname (available for filtering with Q objects).
• Added threading_support argument to hunter.trace: makes new threads be traced and changes action output to include threadname.
• Added support for using pdb++ in the Debugger action.
• Added support for using manhole via a new Manhole action.
• Made the handler a public but readonly property of Tracer objects.

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)

• Fix “KeyError: ‘normal’” bug in CallPrinter. Create the NO_COLORS dict from the COLOR dicts. Some keys were missing.

1.2.0 (2016-01-24)

• Fixed printouts of objects that return very large string in __repr__(). Trimmed to 512. Configurable in actions with the repr_limit option.
• Improved validation of VarsPrinter’s initializer.
• Added a CallPrinter action.

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 VarsPrinter and CodePrinter.
• Allowed setting the stream to a file name (option on VarsPrinter and 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)

• Fixed Event.globals to actually be the dict of global vars (it was just the locals).

0.5.0 (2015-04-06)

• Fixed And and Or “single argument unwrapping”.
• Implemented predicate compression. Example: Or(Or(a, b), c) is converted to Or(a, b, c).
• Renamed the Event.source to Event.fullsource.
• Added Event.source that doesn’t do any fancy sourcecode tokenization.
• Fixed Event.fullsource return value for situations where the tokenizer would fail.
• Made the print function available in the PYTHONHUNTER env var payload.
• Added a __repr__ for Event.

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)

• Added missing color entry for exception events.
• Added Event.line property. It returns the source code for the line being run.

0.2.0 (2015-03-27)

• Added color support (and colorama as dependency).
• Added support for expressions in VarsPrinter.
• Breaking changes:
  • Renamed F to Q. And Q is now just a convenience wrapper for Query.
  • Renamed the PYTHON_HUNTER env variable to PYTHONHUNTER.
  • Changed When to take positional arguments.
  • Changed output to show 2 path components (still not configurable).
  • Changed VarsPrinter to take positional arguments for the names.
• Improved error reporting for env variable activation (PYTHONHUNTER).
• Fixed env var activator (the .pth file) installation with setup.py install (the “egg installs”) and setup.py develop/pip install -e (the “egg links”).

0.1.0 (2015-03-22)

• First release on PyPI.
