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.

bpo-17611. Move unwinding of stack for "pseudo exceptions" from interpreter to compiler. (GH-5006)

2018-02-04T00:36:10+00:00

Fix typos found by codespell in docs, docstrings, and comments.

bpo-32550. Remove the STORE_ANNOTATION bytecode. (GH-5181)

2018-01-30T00:41:04+00:00

Issue #26110: Add LOAD_METHOD/CALL_METHOD opcodes.

2016-12-14T00:03:51+00:00

Special thanks to INADA Naoki for pushing the patch through
the last mile, Serhiy Storchaka for reviewing the code, and to
Victor Stinner for suggesting the idea (originally implemented
in the PyPy project).
