* bpo-45953: Statically allocate the main interpreter (and initial thread ↵Eric Snow2022-01-121-1/+9
| | | | | | | | | state). (gh-29883) Previously, the main interpreter was allocated on the heap during runtime initialization. Here we instead embed it into _PyRuntimeState, which means it is statically allocated as part of the _PyRuntime global. The same goes for the initial thread state (of each interpreter, including the main one). Consequently there are fewer allocations during runtime/interpreter init, fewer possible failures, and better memory locality. FYI, this also helps efforts to consolidate globals, which in turns helps work on subinterpreter isolation. https://bugs.python.org/issue45953
* bpo-46303: Move fileutils.h private functions to internal C API (GH-30484)Victor Stinner2022-01-111-159/+1
| | | | | | | | | | Move almost all private functions of Include/cpython/fileutils.h to the internal C API Include/internal/pycore_fileutils.h. Only keep _Py_fopen_obj() in Include/cpython/fileutils.h, since it's used by _testcapi which must not use the internal C API. Move EncodeLocaleEx() and DecodeLocaleEx() functions from _testcapi to _testinternalcapi, since the C API moved to the internal C API.
* bpo-46218: Change long_pow() to sliding window algorithm (GH-30319)Tim Peters2022-01-021-6/+0
| | | | | | | | | | | * bpo-46218: Change long_pow() to sliding window algorithm The primary motivation is to eliminate long_pow's reliance on that the number of bits in a long "digit" is a multiple of 5. Now it no longer cares how many bits are in a digit. But the sliding window approach also allows cutting the precomputed table of small powers in half, which reduces initialization overhead enough that the approach pays off for smaller exponents too. Depending on exponent bit patterns, a sliding window may also be able to save some bigint multiplies (sometimes when at least 5 consecutive exponent bits are 0, regardless of their starting bit position modulo 5). Note: boosting the window width to 6 didn't work well overall. It give marginal speed improvements for huge exponents, but the increased overhead (the small-power table needs twice as many entries) made it a loss for smaller exponents.

| | | | | | | Exclude the PyUnicode_CHECK_INTERNED() macro from the limited C API, because it uses the PyASCIIObject structure which is excluded from the limited C API. Automerge-Triggered-By: GH:encukou
* bpo-46008: Move Py*State init into distinct functions. (gh-29977)Eric Snow2021-12-081-0/+6
| | | | | Previously, basic initialization of PyInterprterState happened in PyInterpreterState_New() (along with allocation and adding the new interpreter to the runtime state). This prevented us from initializing interpreter states that were allocated separately (e.g. statically or in a free list). We've addressed that here by factoring out a separate function just for initialization. We've done the same for PyThreadState. _PyRuntimeState was sorted out when we added it since _PyRuntime is statically allocated. However, here we update the existing init code to line up with the functions for PyInterpreterState and PyThreadState. https://bugs.python.org/issue46008

* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-032-6/+3
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.

| | | | | | | | | | | | | Split header files to move the non-limited API to Include/cpython/: * Include/warnings.h => Include/cpython/warnings.h * Include/weakrefobject.h => Include/cpython/weakrefobject.h Exclude PyWeakref_GET_OBJECT() from the limited C API. It never worked since the PyWeakReference structure is opaque in the limited C API. Move _PyWarnings_Init() and _PyErr_WarnUnawaitedCoroutine() to the internal C API.
* bpo-43760: Add PyThreadState_EnterTracing() (GH-28542)Victor Stinner2021-10-151-0/+7
| | | | | | | | | | Add PyThreadState_EnterTracing() and PyThreadState_LeaveTracing() functions to the limited C API to suspend and resume tracing and profiling. Add an unit test on the PyThreadState C API to _testcapi. Add also internal _PyThreadState_DisableTracing() and _PyThreadState_ResetTracing().

* bpo-41710: PyThread_acquire_lock_timed() clamps the timout (GH-28643)Victor Stinner2021-09-301-0/+2
| | | | | | | | | | | | | | | | | | | PyThread_acquire_lock_timed() now clamps the timeout into the [_PyTime_MIN; _PyTime_MAX] range (_PyTime_t type) if it is too large, rather than calling Py_FatalError() which aborts the process. PyThread_acquire_lock_timed() no longer uses MICROSECONDS_TO_TIMESPEC() to compute sem_timedwait() argument, but _PyTime_GetSystemClock() and _PyTime_AsTimespec_truncate(). Fix _thread.TIMEOUT_MAX value on Windows: the maximum timeout is 0x7FFFFFFF milliseconds (around 24.9 days), not 0xFFFFFFFF milliseconds (around 49.7 days). Set PY_TIMEOUT_MAX to 0x7FFFFFFF milliseconds, rather than 0xFFFFFFFF milliseconds. Fix PY_TIMEOUT_MAX overflow test: replace (us >= PY_TIMEOUT_MAX) with (us > PY_TIMEOUT_MAX).
* bpo-41710: Add pytime_add() and pytime_mul() (GH-28642)Victor Stinner2021-09-301-3/+5
| | | | | | Add pytime_add() and pytime_mul() functions to pytime.c to compute t+t2 and t*k with clamping to [_PyTime_MIN; _PyTime_MAX]. Fix pytime.h: _PyTime_FromTimeval() is not implemented on Windows.
* bpo-41710: Add _PyTime_AsTimespec_clamp() (GH-28629)Victor Stinner2021-09-301-5/+11
| | | | | | | | | | | | | | | Add the _PyTime_AsTimespec_clamp() function: similar to _PyTime_AsTimespec(), but clamp to _PyTime_t min/max and don't raise an exception. PyThread_acquire_lock_timed() now uses _PyTime_AsTimespec_clamp() to remove the Py_UNREACHABLE() code path. * Add _PyTime_AsTime_t() function. * Add PY_TIME_T_MIN and PY_TIME_T_MAX constants. * Replace _PyTime_AsTimeval_noraise() with _PyTime_AsTimeval_clamp(). * Add pytime_divide_round_up() function. * Fix integer overflow in pytime_divide(). * Add pytime_divmod() function.
