* bpo-35178: Fix warnings._formatwarnmsg() (GH-12033)Xtreak2019-03-011-1/+1
| | | | | Ensure custom formatwarning function can receive line as positional argument. Co-Authored-By: Tashrif Billah <tashrifbillah@gmail.com>
* bpo-29564: warnings suggests to enable tracemalloc (GH-10486)Victor Stinner2018-11-131-6/+17
| | | | | The warnings module now suggests to enable tracemalloc if the source is specified, tracemalloc module is available, but tracemalloc is not tracing memory allocations.
* bpo-33375: Get filename for warnings from frame.f_code.co_filename (GH-6622)Thomas Kluyver2018-06-081-14/+2
| | | More consistent with how other parts of Python find the filename (e.g. tracebacks and pdb).
* bpo-32591: Add native coroutine origin tracking (#5250)Nathaniel J. Smith2018-01-211-0/+23
| | | | | | * Add coro.cr_origin and sys.set_coroutine_origin_tracking_depth * Use coroutine origin information in the unawaited coroutine warning * Stop using set_coroutine_wrapper in asyncio debug mode * In BaseEventLoop.set_debug, enable debugging in the correct thread
* bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458)Nick Coghlan2018-01-081-1/+3
| | | | | | | | | | | | | - primary change is to add a new default filter entry for 'default::DeprecationWarning:__main__' - secondary change is an internal one to cope with plain strings in the warning module's internal filter list (this avoids the need to create a compiled regex object early on during interpreter startup) - assorted documentation updates, including many more examples of configuring the warnings settings - additional tests to ensure that both the pure Python and the C accelerated warnings modules have the expected default configuration
* bpo-32230: Set sys.warnoptions with -X dev (#4820)Victor Stinner2017-12-121-29/+6
| | | | | | | | | | | | | | Rather than supporting dev mode directly in the warnings module, this instead adjusts the initialisation code to add an extra 'default' entry to sys.warnoptions when dev mode is enabled. This ensures that dev mode behaves *exactly* as if `-Wdefault` had been passed on the command line, including in the way it interacts with `sys.warnoptions`, and with other command line flags like `-bb`. Fix also bpo-20361: have -b & -bb options take precedence over any other warnings options. Patch written by Nick Coghlan, with minor modifications of Victor Stinner.
* bpo-32121: Add most_recent_first parameter to tracemalloc.Traceback.format ↵Jesse-Bakker2017-11-291-1/+1
| | | | | | | | (#4534) * Add most_recent_first parameter to tracemalloc.Traceback.format to allow reversing the order of the frames in the output * Reversed default sorting of tracemalloc.Traceback frames * Allowed negative limit, truncating from the other side.
* bpo-27535: Fix memory leak with warnings ignore (#4489)Victor Stinner2017-11-271-1/+0
| | | | | | | The warnings module doesn't leak memory anymore in the hidden warnings registry for the "ignore" action of warnings filters. The warn_explicit() function doesn't add the warning key to the registry anymore for the "ignore" action.
* bpo-32089: Use default action for ResourceWarning (#4584)Victor Stinner2017-11-271-1/+1
| | | | | In development and debug mode, use the "default" action, rather than the "always" action, for ResourceWarning in the default warnings filters.
* bpo-27535: Optimize warnings.warn() (#4508)Victor Stinner2017-11-221-3/+14
| | | | | | | | | | | | | * Optimize warnings.filterwarnings(). Replace re.compile('') with None to avoid the cost of calling a regex.match() method, whereas it always matchs. * Optimize get_warnings_attr(): replace PyObject_GetAttrString() with _PyObject_GetAttrId(). Cleanup also create_filter(): * Use _Py_IDENTIFIER() to allow to cleanup strings at Python finalization * Replace Py_FatalError() with a regular exceptions
* bpo-32089: Fix warnings filters in dev mode (#4482)Victor Stinner2017-11-211-3/+11
| | | | | | | | | | The developer mode (-X dev) now creates all default warnings filters to order filters in the correct order to always show ResourceWarning and make BytesWarning depend on the -b option. Write a functional test to make sure that ResourceWarning is logged twice at the same location in the developer mode. Add a new 'dev_mode' field to _PyCoreConfig.
* bpo-32088: Display Deprecation in debug mode (#4474)Victor Stinner2017-11-201-5/+9
| | | | | | | | When Python is build is debug mode (Py_DEBUG), DeprecationWarning, PendingDeprecationWarning and ImportWarning warnings are now displayed by default. test_venv: run "-m pip" and "-m ensurepip._uninstall" with -W ignore::DeprecationWarning since pip code is not part of Python.
* Simplify code in warnings modules (#1935)Alex Gaynor2017-06-041-3/+7
| | | Metaprogramming a list of attributes was excessive, and made the code less readable and slower.
* bpo-29762: More use "raise from None". (#569)Serhiy Storchaka2017-04-051-4/+4
| | | This hides unwanted implementation details from tracebacks.

|/ | | | | | | | | | | | | Issue #26568: add new _showwarnmsg() and _formatwarnmsg() functions to the warnings module. The C function warn_explicit() now calls warnings._showwarnmsg() with a warnings.WarningMessage as parameter, instead of calling warnings.showwarning() with multiple parameters. _showwarnmsg() calls warnings.showwarning() if warnings.showwarning() was replaced. Same for _formatwarnmsg(): call warnings.formatwarning() if it was replaced.

* _warnings exposed two variables with the name 'default_action' andBrett Cannon2010-09-041-3/+3
| | | | | | | | | | | 'once_registry'. This is bad as the warnings module had variables named 'defaultaction' and 'onceregistry' which are what people should be looking at (technically those variables shouldn't be mucked with as they are undocumented, but we all know better than to believe that isn't happening). So the variables from _warnings have been renamed to come off as private and to avoid confusion over what variable should be used. Closes issue #9766. Thanks to Antoine Pitrou for the discovery.

This was originally suggested by Guido, discussed on the stdlib-sig mailing list, and given the OK by Guido directly to me. What this change essentially means is that Python has taken a policy of silencing warnings that are only of interest to developers by default. This should prevent users from seeing warnings which are triggered by an application being run against a new interpreter before the app developer has a chance to update their code. Closes issue #7319.

Since Py3K warnings are DeprecationWarning by default this was causing -3 to essentially be a no-op. Now DeprecationWarning is only silenced if -3 is not used. Closes issue #7700.
