Serhiy Storchaka bec802dbb8 gh-77560: Report possible errors in restoring builtins at finalization (GH-94255)
Seems in the past the copy of builtins was not made in some scenarios,
and the error was silenced. Write it now to stderr, so we have a chance
to see it.

Mark Shannon 6f8875eba3 GH-93841: Allow stats to be turned on and off, cleared and dumped at runtime. (GH-93843) 2022-06-21 15:40:54 +01:00
Victor Stinner c7a79bb036 gh-74953: _PyThread_cond_after() uses _PyTime_t (#94056)
pthread _PyThread_cond_after() implementation now uses the _PyTime_t
type to handle properly overflow: clamp to the maximum value.

Remove MICROSECONDS_TO_TIMESPEC() function.

Dennis Sweeney 5fcfdd87c9 GH-91432: Specialize FOR_ITER (GH-91713)

Irit Katriel 889772fb56 GH-93678: refactor compiler so that optimizer does not need the assembler and compiler structs (GH-93842) 2022-06-21 09:22:17 +01:00

Victor Stinner cfb986a1a2 gh-93937: PyOS_StdioReadline() uses PyConfig.legacy_windows_stdio (#94024)
On Windows, PyOS_StdioReadline() now gets
PyConfig.legacy_windows_stdio from _PyOS_ReadlineTState, rather than
using the deprecated global Py_LegacyWindowsStdioFlag variable.

Fix also a compiler warning in Py_SetStandardStreamEncoding().

Mark Shannon ab0e601016 GH-93516: Speedup line number checks when tracing. (GH-93763)

Mark Shannon 45e62a2bc1 GH-93897: Store frame size in code object and de-opt if insufficient space on thread frame stack. (GH-93908) 2022-06-20 12:59:25 +01:00
Victor Stinner 27b9894033 gh-93937, C API: Move PyFrame_GetBack() to Python.h (#93938)
Move the follow functions and type from frameobject.h to pyframe.h,
so the standard <Python.h> provide frame getter functions:

* PyFrame_Check()
* PyFrame_GetBack()
* PyFrame_GetBuiltins()
* PyFrame_GetGenerator()
* PyFrame_GetGlobals()
* PyFrame_GetLasti()
* PyFrame_GetLocals()
* PyFrame_Type

Remove #include "frameobject.h" from many C files. It's no longer
needed.

Victor Stinner 2664d9aacf gh-74953: Reformat PyThread_acquire_lock_timed() (#93947)
Reformat the pthread implementation of PyThread_acquire_lock_timed()
using a mutex and a conditioinal variable.

* Add goto to avoid multiple indentation levels and exit quickly
* Use "while(1)" and make the control flow more obvious.
* PEP 7: Add braces around if blocks.

Victor Stinner 0ff626f210 gh-77782: Deprecate global configuration variable (#93943)
Deprecate global configuration variable like
Py_IgnoreEnvironmentFlag: the Py_InitializeFromConfig() API should be
instead.

Fix declaration of Py_GETENV(): use PyAPI_FUNC(), not PyAPI_DATA().

Eric Snow caa279d6fd bpo-40514: Drop EXPERIMENTAL_ISOLATED_SUBINTERPRETERS (gh-93185)
This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing:

* the configure option
* the macro
* the code enabled by the macro
