on the action's default, reverting it back to previous behavior.  Conversion
is only done on string defaults.

Add a test for this and another test that ensures such type conversions are
only called once.

Cleanup 'k' when the creation of PySTEntryObject fails. ad3824a90261 used to decref 'k' in too many error cases.

  when action='append', type='str' and default=[].

Closes #15793: Stack corruption in ssl.RAND_egd(). Python 2.7 hasn't any issue about this, but add a test just to be sure

Fixed memory leak in error branch of object_repr which may leak a reference to mod when type_name returns NULL. CID 715371

Also adds tests to verify the documented behavior (which is probably a bug, as
indicated in the added comments).

BSD's make doesn't support some of the features.

This fixes a regression introduced by the fix for issue #13922.  Although args
is not documented as being allowed to be a tuple, previously this worked and
so naturally there are programs in the field that depend on it.

Patch by Zbyszek Jędrzejewski-Szmek.

This was a regression caused by the hash randomization patch.

BSD's make doesn't support some of the features.

sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.

Because of this change, a couple extension modules compiled for 2.7.4
(those which use the trashcan mechanism, despite it being undocumented)
will not be loadable by 2.7.3 and earlier. However, extension modules
compiled for 2.7.3 and earlier will be loadable by 2.7.4.
