Work towards feature_version support

2019-03-05T19:36:11+00:00

Visible behavior:

- Issue error for `X @ Y` (matrix multiply) if c_feature_version < 5

- Add optional feature_version kw arg to ast.parse() (default -1 which
  implies PY_MINOR_VERSION)

- Add feature_version: int = -1 to compile() (via Argument Clinic);
  this sets cf_feature_version to the given value if >= 0, else
  defaults to PY_MINOR_VERSION

Implementation:

- Add PyAST_obj2mod_ex(): like PyAST_obj2mod() but with feature_version arg;
  the latter calls the former with PY_MINOR_VERSION

- Add cf_feature_version to PyCompilerFlags structure;
  initialized to PY_MINOR_VERSION everywhere

- Add c_feature_version to struct compiling; initialize from
  cf_feature_version

- Add 'c' argument to get_operator()

- In builtin eval() and exec(), default to PY_MINOR_VERSION

TODO:

- Put version-dependent ASYNC/AWAIT keyword scanning back

- Reject async functions, await expressions, and async for/with in minor versions < 5

- Reject async comprehensions in minor versions < 6

- Reject underscores in numeric literals in minor versions < 6

- Reject variable annotations in minor versions < 6

- Reject `X @= Y` in minor versions < 5

Fix the C function signature for _collections._tuplegetter.reduce. (GH-12180)

2019-03-05T16:41:09+00:00

Correctly fixes bpo-36197.

bpo-33012: Fix compilation warnings in memoryobject.c and _collectionsmodule.c (GH-12179)

2019-03-05T15:10:53+00:00

Cast function pointers to (void(*)(void)) before casting to (PyCFunction)
to make "warning: cast between incompatible function types" false alarm quiet.

bpo-36142: Add _PyPreConfig_ReadFromArgv() (GH-12173)

2019-03-05T01:44:12+00:00

The new function is now responsible to parse -E and -I command line
arguments.

bpo-36142: Add _PyPreConfig structure (GH-12172)

2019-03-05T01:01:27+00:00

* Add _PyPreConfig structure
* Move 'ignored' and 'use_environment' fields from _PyCoreConfig
  to _PyPreConfig
* Add a new "_PyPreConfig preconfig;" field to _PyCoreConfig

bpo-36179: Fix ref leaks in _hashopenssl (GH-12158)

2019-03-04T15:45:41+00:00

Fix two unlikely reference leaks in _hashopenssl. The leaks only occur in
out-of-memory cases. Thanks to Charalampos Stratakis.

add missing break statement (GH-12147)

2019-03-03T16:22:39+00:00

Bug introduced by 848037c.

Use names SEEK_SET, etc instead of magic number (GH-12057)

2019-03-03T07:28:26+00:00

The previous code hardcoded `SEEK_SET`, etc. While it's very unlikely
that these values will change, it's best to use the definitions to avoid
there being mismatches in behavior with the code in the future.
