bpo-38858: Small integer per interpreter (GH-17315)

2019-12-17T12:02:18+00:00

Each Python subinterpreter now has its own "small integer
singletons": numbers in [-5; 257] range.

It is no longer possible to change the number of small integers at
build time by overriding NSMALLNEGINTS and NSMALLPOSINTS macros:
macros should now be modified manually in pycore_pystate.h header
file.

For now, continue to share _PyLong_Zero and _PyLong_One singletons
between all subinterpreters.

bpo-38629: implement floor and ceil for float type (GH-16985)

bpo-27961: Replace PY_LLONG_MAX, PY_LLONG_MIN and PY_ULLONG_MAX with standard macros (GH-15385)

2019-12-05T14:55:28+00:00

Use standard constants LLONG_MIN, LLONG_MAX and ULLONG_MAX.

Fix compiler warning in Objects/unicodeobject.c (GH-17440)

bpo-38896: Remove PyUnicode_ClearFreeList() function (GH-17354)

2019-11-23T01:30:32+00:00

Remove PyUnicode_ClearFreeList() function: the Unicode free list has
been removed in Python 3.3.

bpo-38858: Call _PyUnicode_Fini() in Py_EndInterpreter() (GH-17330)

2019-11-22T11:27:50+00:00

Py_EndInterpreter() now clears the filesystem codec.

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-38858: Allocate small integers on the heap (GH-17301)

2019-11-21T07:51:59+00:00

Allocate small Python integers (small_ints of longobject.c) on the
heap, rather than using static objects.
