* bpo-37705: Remove orphaned PC/errmap.mak (GH-29724)Oleg Iarygin2022-02-021-5/+0
| | | | | | | After GH-15623 deleted `generrmap.c`, a related mak-file stopped working. The mak contains generrmap-related rules only so it should be removed altogether. Further search for `errmap\.mak|generrmap` regex through content of CPython files shows no dangling reference left. Since generrmap is already effectively removed, this pull request contains no blurp.

* bpo-43931: Export Python version as API data (GH-25577)Gabriele N. Tornetta2021-12-101-0/+1
| | | | | When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

* bpo-45947: Place dict and values pointer at fixed (negative) offset just ↵Mark Shannon2021-12-071-1/+0
| | | | | | | | | | | | | | | | | | | before GC header. (GH-29879) * Place __dict__ immediately before GC header for plain Python objects. * Fix up lazy dict creation logic to use managed dict pointers. * Manage values pointer, placing them directly before managed dict pointers. * Convert hint-based load/store attr specialization target managed dict classes. * Specialize LOAD_METHOD for managed dict objects. * Remove unsafe _PyObject_GC_Calloc function. * Remove unsafe _PyObject_GC_Malloc() function. * Add comment explaning use of Py_TPFLAGS_MANAGED_DICT.
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-033-1179/+4
| | | | | 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.

* bpo-45522: Allow to disable freelists on build time (GH-29056)Christian Heimes2021-10-211-0/+3
| | | | | | | | Freelists for object structs can now be disabled. A new ``configure`` option ``--without-freelists`` can be used to disable all freelists except empty tuple singleton. Internal Py*_MAXFREELIST macros can now be defined as 0 without causing compiler warnings and segfaults. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-45440: Remove pymath.c fallbacks (GH-28977)Victor Stinner2021-10-151-9/+0
| | | | | | | | Remove fallbacks for missing round(), copysign() and hypot() in Python/pymath.c. Python now requires these functions to build. These fallbacks were needed on Visual Studio 2012 and older. They are no longer needed since Visual Stuido 2013. Python is now built with Visual Studio 2017 or newer since Python 3.6.
* bpo-45440: Require math.h isinf() to build (GH-28894)Victor Stinner2021-10-131-12/+1
| | | | | | | | | | | | | | | Building Python now requires a C99 <math.h> header file providing isinf(), isnan() and isfinite() functions. Remove the Py_FORCE_DOUBLE() macro. It was used by the Py_IS_INFINITY() macro. Changes: * Remove Py_IS_NAN(), Py_IS_INFINITY() and Py_IS_FINITE() in PC/pyconfig.h. * Remove the _Py_force_double() function. * configure no longer checks if math.h defines isinf(), isnan() and isfinite().
* bpo-45434: pyport.h no longer includes <stdlib.h> (GH-28914)Victor Stinner2021-10-131-0/+1

| | | | | During runtime startup we figure out the stdlib dir but currently throw that information away. This change preserves it and exposes it via PyConfig.stdlib_dir, _Py_GetStdlibDir(), and sys._stdlib_dir. https://bugs.python.org/issue45211
* bpo-45211: Move helpers from getpath.c to internal API. (gh-28550)Eric Snow2021-09-271-26/+29
| | | | | | | | | | | | This accomplishes 2 things: * consolidates some common code between getpath.c and getpathp.c * makes the helpers available to code in other files FWIW, the signature of the join_relfile() function (in fileutils.c) intentionally mirrors that of Windows' PathCchCombineEx(). Note that this change is mostly moving code around. No behavior is meant to change. https://bugs.python.org/issue45211

* bpo-45188: Windows now regenerates frozen modules at the start of build ↵Steve Dower2021-09-151-0/+53
| | | | | | | instead of late (GH-28322) This will enable us to drop the frozen module header files from the repository. It does currently cause many source files to be built twice, which just takes more time. For whoever comes to fix this in the future, the files shared between freeze_module and pythoncore should be put into a static library that is consumed by both.

* bpo-39947: Remove old private trashcan C API functions (GH-26869)Victor Stinner2021-06-231-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove 4 C API private trashcan functions which were only kept for the backward compatibility of the stable ABI with Python 3.8 and older, since the trashcan API was not usable with the limited C API on Python 3.8 and older. The trashcan API was excluded from the limited C API in Python 3.9. Removed functions: * _PyTrash_deposit_object() * _PyTrash_destroy_chain() * _PyTrash_thread_deposit_object() * _PyTrash_thread_destroy_chain() The trashcan C API was never usable with the limited C API, since old trashcan macros accessed directly PyThreadState members like "_tstate->trash_delete_nesting", whereas the PyThreadState structure is opaque in the limited C API. Exclude also the PyTrash_UNWIND_LEVEL constant from the C API. The trashcan C API was modified in Python 3.9 by commit 38965ec5411da60d312b59be281f3510d58e0cf1 and in Python 3.10 by commit ed1a5a5baca8f61e9a99c5be3adc16b1801514fe to hide implementation details.

* bpo-43795: Remove Py_FrozenMain from the Limited API & Stable ABI (GH-26241)Petr Viktorin2021-05-251-1/+0
| | | | | | | | | | | Py_FrozenMain was added to the Limited C API in [bpo-42591]() (3.10.0a4); but to fix that issue it would be enough to add it to the regular C API. The function is undocumented, tests were added very recently ([bpo-44131]()), and most importantly, it is not present in all builds of Python, as the linker sometimes omits it as unused. It should be added back when these issues are fixed. Note that this does not affect Python's regular C API.
* bpo-40222: "Zero cost" exception handling (GH-25729)Mark Shannon2021-05-071-1/+2
| | | | | | | | "Zero cost" exception handling. * Uses a lookup table to determine how to handle exceptions. * Removes SETUP_FINALLY and POP_TOP block instructions, eliminating (most of) the runtime overhead of try statements. * Reduces the size of the frame object by about 60%.

* bpo-30555: Fix WindowsConsoleIO fails in the presence of fd redirection ↵Segev Finer2021-04-232-21/+8
| | | | | | | | (GH-1927) This works by not caching the handle and instead getting the handle from the file descriptor each time, so that if the actual handle changes by fd redirection closing/opening the console handle beneath our feet, we will keep working correctly.
