* Fix a reference leak in the compiler for compiler_lambda() (GH-24382)Pablo Galindo2021-01-291-1/+3

* bpo-42979: Use _Py_CheckSlotResult() to check slots result (GH-24356)Victor Stinner2021-01-291-7/+11
| | | | | | | | | | | | | | | When Python is built in debug mode (with C assertions), calling a type slot like sq_length (__len__() in Python) now fails with a fatal error if the slot succeeded with an exception set, or failed with no exception set. The error message contains the slot, the type name, and the current exception (if an exception is set). * Check the result of all slots using _Py_CheckSlotResult(). * No longer pass op_name to ternary_op() in release mode. * Replace operator with dunder Python method name in error messages. For example, replace "*" with "__mul__". * Fix compiler_exit_scope() when an exception is set. * Fix bytearray.extend() when an exception is set: don't call bytearray_setslice() with an exception set.

| | | | | | | | | | | | | | | | | | | | | | | (GH-23733) * Delete jump instructions that bypass empty blocks * Add news entry * Explicitly check for unconditional jump opcodes Using the is_jump function results in the inclusion of instructions like returns for which this optimization is not really valid.

* bpo-42349: Compiler clean up. More yak-shaving for PEP 626. (GH-23267)Mark Shannon2020-11-171-60/+127
| | | Make sure that CFG from compiler front-end is correct. Be a bit more aggressive in the compiler back-end.
* bpo-42246: Fix memory leak in compiler (GH-23256)Mark Shannon2020-11-131-7/+13
| | | | | * Fix potential memory leak in assembler init. * Fix reference leak when encountering error during compilation of function body.

| | | * Implement new line number table format, as defined in PEP 626.
* bpo-42161: Use _PyLong_GetZero() and _PyLong_GetOne() (GH-22995)Victor Stinner2020-10-271-2/+4
| | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Objects/ and Python/ directories.
* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-3/+3
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
* bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)Batuhan Taskaya2020-10-061-12/+2
| | | | | The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions. For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).
* bpo-39934: Account for control blocks in 'except' in compiler. (GH-22395)Mark Shannon2020-09-251-8/+11
| | | * Account for control blocks in 'except' in compiler. Fixes #39934.
* bpo-40941: Fix fold_tuple_on_constants() compiler warnings (GH-22378)Victor Stinner2020-09-231-4/+2
| | | | | | Add explicit casts to fix compiler warnings in fold_tuple_on_constants(). The limit of constants per code is now INT_MAX, rather than UINT_MAX.
* bpo-41746: Add type information to asdl_seq objects (GH-22223)Pablo Galindo2020-09-161-40/+37
| | | | | | | | | | | | | * Add new capability to the PEG parser to type variable assignments. For instance: ``` | a[asdl_stmt_seq*]=';'.small_stmt+ [';'] NEWLINE { a } ``` * Add new sequence types from the asdl definition (automatically generated) * Make `asdl_seq` type a generic aliasing pointer type. * Create a new `asdl_generic_seq` for the generic case using `void*`. * The old `asdl_seq_GET`/`ast_seq_SET` macros now are typed. * New `asdl_seq_GET_UNTYPED`/`ast_seq_SET_UNTYPED` macros for dealing with generic sequences. * Changes all possible `asdl_seq` types to use specific versions everywhere.

* bpo-41218: Only mark async code with CO_COROUTINE. (#21357)Matthias Bussonnier2020-07-061-4/+6
| | | | | 3.8.3 had a regression where compiling with ast.PyCF_ALLOW_TOP_LEVEL_AWAIT woudl agressively mark things are coroutine even if there were not.
