[3.10] Remove trailing spaces (GH-28709)

2021-10-03T17:03:49+00:00

When printing stats, move radix tree info to its own section. (GH-25125)

2021-04-01T03:46:31+00:00

When printing stats, move radix tree info to its own section.
Restore that the breakdown of bytes in arenas exactly accounts for the total of arena bytes allocated.
Add an assert so that invariant doesn't break again.

bpo-37448: Use radix tree for pymalloc address_in_range(). (GH-14474)

2021-03-30T02:51:15+00:00

The radix tree approach is a relatively simple and memory sanitary
alternative to the old (slightly) unsanitary address_in_range().
To disable the radix tree map, set a preprocessor flag as follows:
-DWITH_PYMALLOC_RADIX_TREE=0.

bpo-40943: Replace PY_FORMAT_SIZE_T with "z" (GH-20781)

2020-06-10T16:38:05+00:00

The PEP 353, written in 2005, introduced PY_FORMAT_SIZE_T. Python no
longer supports macOS 10.4 and Visual Studio 2010, but requires more
recent macOS and Visual Studio versions. In 2020 with Python 3.10, it
is now safe to use directly "%zu" to format size_t and "%zi" to
format Py_ssize_t.

bpo-39882: Add _Py_FatalErrorFormat() function (GH-19157)

bpo-39882: Py_FatalError() logs the function name (GH-18819)

2020-03-06T23:54:20+00:00

The Py_FatalError() function is replaced with a macro which logs
automatically the name of the current function, unless the
Py_LIMITED_API macro is defined.

Changes:

* Add _Py_FatalErrorFunc() function.
* Remove the function name from the message of Py_FatalError() calls
  which included the function name.
* Update tests.

bpo-38733: PyErr_Occurred() caller must hold the GIL (GH-17080)

2019-11-07T11:42:07+00:00

bpo-3605, bpo-38733: Optimize _PyErr_Occurred(): remove "tstate ==
NULL" test.

Py_FatalError() no longer calls PyErr_Occurred() if called without
holding the GIL. So PyErr_Occurred() no longer has to support
tstate==NULL case.

_Py_CheckFunctionResult(): use directly _PyErr_Occurred() to avoid
explicit "!= NULL" test.
