bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)

2020-04-14T13:14:01+00:00

Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET()
for consistency with _PyThreadState_GET() and to have a shorter name
(help to fit into 80 columns).

Add also "assert(tstate != NULL);" to the function.

bpo-40268: Include explicitly pycore_interp.h (GH-19505)

2020-04-14T12:26:24+00:00

pycore_pystate.h no longer includes pycore_interp.h:
it's now included explicitly in files accessing PyInterpreterState.

bpo-39947: Use _PyInterpreterState_GET_UNSAFE() (GH-18978)

2020-03-13T17:03:56+00:00

Replace _PyInterpreterState_Get() function call with
_PyInterpreterState_GET_UNSAFE() macro which is more efficient but
don't check if tstate or interp is NULL.

_Py_GetConfigsAsDict() now uses _PyThreadState_GET().

bpo-36722: Debug build loads libraries built in release mode (GH-12952)

2019-04-25T23:40:00+00:00

In debug build, import now also looks for C extensions compiled in
release mode and for C extensions compiled in the stable ABI.

bpo-28401: prevent Py_DEBUG builds from trying to import limited ABI modules (GH-1766)

2018-11-16T23:52:52+00:00

[Issue 28401](https://bugs.python.org/issue28401): Don't attempt to import the stable API extensions, they are not supported in PyDEBUG builds (which don't implement that ABI).

bpo-35081: Rename internal headers (GH-10275)

2018-11-12T15:53:38+00:00

Rename Include/internal/ headers:

* pycore_hash.h -> pycore_pyhash.h
* pycore_lifecycle.h -> pycore_pylifecycle.h
* pycore_mem.h -> pycore_pymem.h
* pycore_state.h -> pycore_pystate.h

Add missing headers to Makefile.pre.in and PCbuild:

* pycore_condvar.h.
* pycore_hamt.h
* pycore_pyhash.h

bpo-35081: Add pycore_ prefix to internal header files (GH-10263)

2018-10-31T23:52:28+00:00

* Rename Include/internal/ header files:

  * pyatomic.h -> pycore_atomic.h
  * ceval.h -> pycore_ceval.h
  * condvar.h -> pycore_condvar.h
  * context.h -> pycore_context.h
  * pygetopt.h -> pycore_getopt.h
  * gil.h -> pycore_gil.h
  * hamt.h -> pycore_hamt.h
  * hash.h -> pycore_hash.h
  * mem.h -> pycore_mem.h
  * pystate.h -> pycore_state.h
  * warnings.h -> pycore_warnings.h

* PCbuild project, Makefile.pre.in, Modules/Setup: add the
  Include/internal/ directory to the search paths of header files.
* Update includes. For example, replace #include "internal/mem.h"
  with #include "pycore_mem.h".

bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)

2018-08-03T13:33:52+00:00

sys_setcheckinterval() now uses a local variable to parse arguments,
before writing into interp->check_interval.

bpo-30860: Consolidate stateful runtime globals. (#3397)

2017-09-08T05:51:28+00:00

* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

PEP 489: Multi-phase extension module initialization

2015-05-23T12:24:10+00:00

Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.
