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-38858: Fix ref leak in pycore_interp_init() (GH-17512)

2019-12-08T20:55:58+00:00

bpo-38858, bpo-38997: _PySys_Create() returns a strong reference to
the sys module: Py_DECREF() is needed when we are done with the
module.

bpo-38858: Add pycore_interp_init() code to factorize code (GH-17483)

2019-12-06T02:37:07+00:00

Add a new pycore_interp_init() function called by new_interpreter()
and pyinit_config().

bpo-38858: new_interpreter() reuses _PySys_Create() (GH-17481)

2019-12-06T01:43:30+00:00

new_interpreter() now calls _PySys_Create() to create a new sys
module isolated from the main interpreter. It now calls
_PySys_InitCore() and _PyImport_FixupBuiltin().

init_interp_main() now calls _PySys_InitMain().

Remove unused variable in Python/pylifecycle.c (GH-17475)

bpo-38858: new_interpreter() uses pycore_init_import_warnings() (GH-17353)

2019-11-22T20:54:33+00:00

bpo-38858: new_interpreter() reuses pycore_init_builtins() (GH-17351)

2019-11-22T18:24:49+00:00

new_interpreter() now calls _PyBuiltin_Init() to create the builtins
module and calls _PyImport_FixupBuiltin(), rather than using
_PyImport_FindBuiltin(tstate, "builtins").

pycore_init_builtins() is now responsible to initialize
intepr->builtins_copy: inline _PyImport_Init() and remove this
function.

bpo-38858: Add init_interp_main() subfunction (GH-17347)

2019-11-22T16:52:42+00:00

Fix new_interpreter() error handling: undo it all if status is an
exception.
