bpo-42246: Make sure that `f_lasti`, and thus `f_lineno`, is set correctly after raising or reraising an exception (GH-23803)

2020-12-17T13:55:28+00:00

* Ensure that f_lasti is set correctly after an exception is raised to conform to PEP 626.

* Update importlib

* Add NEWS.

bpo-39320: Handle unpacking of **values in compiler (GH-18141)

2020-01-27T09:57:45+00:00

* Add DICT_UPDATE and DICT_MERGE bytecodes. Use them for ** unpacking.

* Remove BUILD_MAP_UNPACK and BUILD_MAP_UNPACK_WITH_CALL, as they are now unused.

* Update magic number for ** unpacking opcodes.

* Update dis.rst to incorporate new bytecodes.

* Add blurb entry.

bpo-39320: Handle unpacking of *values in compiler (GH-17984)

2020-01-23T09:25:17+00:00

* Add three new bytecodes: LIST_TO_TUPLE, LIST_EXTEND, SET_UPDATE. Use them to implement star unpacking expressions.

* Remove four bytecodes BUILD_LIST_UNPACK, BUILD_TUPLE_UNPACK, BUILD_SET_UNPACK and  BUILD_TUPLE_UNPACK_WITH_CALL opcodes as they are now unused.

* Update magic number and dis.rst for new bytecodes.

bpo-39156: Break up COMPARE_OP into four logically distinct opcodes. (GH-17754)

2020-01-14T10:12:45+00:00

Break up COMPARE_OP into four logically distinct opcodes:
* COMPARE_OP for rich comparisons
* IS_OP for 'is' and 'is not' tests
* CONTAINS_OP for 'in' and 'is not' tests
* JUMP_IF_NOT_EXC_MATCH for checking exceptions in 'try-except' statements.

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-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-33041: Rework compiling an "async for" loop. (#6142)

2018-03-23T12:34:35+00:00

* Added new opcode END_ASYNC_FOR.
* Setting global StopAsyncIteration no longer breaks "async for" loops.
* Jumping into an "async for" loop is now disabled.
* Jumping out of an "async for" loop no longer corrupts the stack.
* Simplify the compiler.
