bpo-29564: warnings suggests to enable tracemalloc (GH-10486)
The warnings module now suggests to enable tracemalloc if the source
is specified, tracemalloc module is available, but tracemalloc is not
tracing memory allocations.

Nick Coghlan 9b99747386
bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458)
- 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)
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-27535: Fix memory leak with warnings ignore (#4489)

  it always matchs.

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)
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.

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.

Brett Cannon ef0e6c3b04 _warnings exposed two variables with the name 'default_action' and
'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.

  DeprecationWarning is now silent by default.

  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. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin
  for helping with the issue.

  The silencing of DeprecationWarning was not taking -3 into consideration. 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. Thanks Ezio Melotti and Florent Xicluna for patch help.
