Produce cleaner bytecode for 'with' and 'async with' by generating separate code for normal and exceptional paths. (#6641)

2019-11-21T09:11:43+00:00

Remove BEGIN_FINALLY, END_FINALLY, CALL_FINALLY and POP_FINALLY bytecodes. Implement finally blocks by code duplication.
Reimplement frame.lineno setter using line numbers rather than bytecode offsets.

bpo-35923: Update the BuiltinImporter to use loader._ORIGIN instead of a hard-coded value (GH-15651)

2019-09-11T16:00:02+00:00

bpo-34880: Add the LOAD_ASSERTION_ERROR opcode. (GH-15073)

2019-08-25T09:44:09+00:00

Fix assert statement misbehavior if AssertionError is shadowed.

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

2019-08-24T10:11:52+00:00

Fix compilation of "break" and "continue" in the
"finally" block when the corresponding "try" block
contains "return" with a non-constant value.

bpo-37685: Fixed eq, lt etc implementations in some classes. (GH-14952)

2019-08-08T05:42:54+00:00

They now return NotImplemented for unsupported type of the other operand.

bpo-37444: Update differing exception between builtins and importlib (GH-14869)

2019-08-03T05:46:02+00:00

Imports now raise `TypeError` instead of `ValueError` for relative import failures. This makes things consistent between `builtins.__import__` and `importlib.__import__` as well as using a more natural import for the failure.

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

2019-06-13T18:16:22+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

* Update marshal.c

* Update compiler and symtable

* Regenerate importlib files

* Update callable objects

* Implement positional-only args logic in ceval.c

* Regenerate frozen data

* Update standard library to account for positional-only args

* Add test file for positional-only args

* Update other test files to account for positional-only args

* Add News entry

* Update inspect module and related tests

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.
