[3.8] bpo-37830: Fix compilation of break and continue in finally. (GH-15320) (GH-15456)

2019-08-24T10:41:53+00:00

Fix compilation of "break" and "continue" in the
"finally" block when the corresponding "try" block
contains "return" with a non-constant value.
(cherry picked from commit ef61c524ddeeb56da3858b86e349e7288d68178e)

bpo-37213: Handle negative line deltas correctly in the peephole optimizer (GH-13969)

2019-06-13T18:35:40+00:00

The peephole optimizer was not optimizing correctly bytecode after negative deltas were introduced. This is due to the fact that some special values (255) were being searched for in both instruction pointer delta and line number deltas.

bpo-36829: Add sys.unraisablehook() (GH-13187)

2019-05-22T09:28:22+00:00

Add new sys.unraisablehook() function which can be overridden to
control how "unraisable exceptions" are handled. It is called when an
exception has occurred but there is no way for Python to handle it.
For example, when a destructor raises an exception or during garbage
collection (gc.collect()).

Changes:

* Add an internal UnraisableHookArgs type used to pass arguments to
  sys.unraisablehook.
* Add _PyErr_WriteUnraisableDefaultHook().
* The default hook now ignores exception on writing the traceback.
* test_sys now uses unittest.main() to automatically discover tests:
  remove test_main().
* Add _PyErr_Init().
* Fix PyErr_WriteUnraisable(): hold a strong reference to sys.stderr
  while using it

bpo-35321: Set the spec origin to frozen in frozen modules (#11732)

2019-02-05T00:56:26+00:00

* bpo-35321: Set the spec origin to frozen in frozen modules

This fix correctly sets the spec origin to
"frozen" for the _frozen_importlib module. Note that the
origin was already correctly set in _frozen_importlib_external.

bpo-34100: Merge constants recursively (GH-8341)

2018-11-26T12:23:22+00:00

There are some same consts in a module.  This commit merges them into
single instance.  It reduces number of objects in memory after loading modules.

bpo-34876: Change the lineno of the AST for decorated function and class. (GH-9731)

2018-10-30T11:16:02+00:00

It was overridden by the lineno of the first decorator. Now it is
the lineno of 'def' or 'class'.

bpo-33331: Clean modules in the reversed order in PyImport_Cleanup(). (GH-6565)

2018-10-29T17:30:16+00:00

Modules imported last are now cleared first at interpreter shutdown.

A newly imported module is moved to the end of sys.modules, behind
modules on which it depends.
