* 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...).

| | | | | | I tried to be relatively thorough and give lots of links. One reason is that this wasn't deprecated very long; also it seems people running into this tend to not be familiar with similar APIs. Co-authored-by: Ken Jin <28750310+Fidget-Spinner@users.noreply.github.com>
* bpo-44392: Add Py_GenericAlias to C API docs (GH-26724)Ken Jin2021-06-161-1/+1

* bpo-43795: Don't list private names in the limited API (GH-26740)Petr Viktorin2021-06-161-2/+1
| | | | | | | | | | | | | * Remove struct _node from the stable ABI list This struct was removed along with the old parser in Python 3.9 (PEP 617) * Stable ABI list: Use the public name "PyFrameObject" rather than "_frame" * Ensure limited API doesn't contain private names Names prefixed by an underscore are private by definition. * Add a blurb
* 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-43795: PEP 652 user documentation (GH-25668)Petr Viktorin2021-05-111-953/+861
| | | | | | - Reformat the C API and ABI Versioning page (and extend/clarify a bit) - Rewrite the stable ABI docs into a general text on C API Compatibility - Add a list of Limited API contents, and notes for the individual items. - Replace `Include/README.rst` with a link to a devguide page with the same info
* bpo-44029: Remove Py_UNICODE APIs (GH-25881)Inada Naoki2021-05-071-84/+0

| | | | | | | | Add new C-API functions to control the state of the garbage collector: PyGC_Enable(), PyGC_Disable(), PyGC_IsEnabled(), corresponding to the functions in the gc module. Co-authored-by: Pablo Galindo <Pablogsal@gmail.com> Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-43795: PEP-652: Clean up the stable ABI/limited API (GH-25482)Petr Viktorin2021-04-231-6/+1
| | | | | | | | | | | | | | | | | | - `_Py_EncodeLocaleRaw`, which is private by name, undocumented, and wasn't exported in `python3.dll`, is moved to a private header. - `_Py_HashSecret_Initialized`, again private by name, undocumented, and not exported in `python3.dll`, is excluded with `Py_LIMITED_API`. - `PyMarshal_*` and `PyMember_*One` functions, declared in private headers and not exported in `python3.dll`, are removed from `Doc/data/stable_abi.dat`. - `PyMem_Calloc` which *was* exported in `python3dll.c`, is moved to public headers where it joins its other `PyMem_*` friends. Only the last change is documented in the blurb; others are not user-visible. (Nothing uses `Doc/data/stable_abi.dat` yet.) https://bugs.python.org/issue43795
* bpo-43753: Add Py_Is() and Py_IsNone() functions (GH-25227)Victor Stinner2021-04-101-0/+4
| | | | | | | Add the Py_Is(x, y) function to test if the 'x' object is the 'y' object, the same as "x is y" in Python. Add also the Py_IsNone(), Py_IsTrue(), Py_IsFalse() functions to test if an object is, respectively, the None singleton, the True singleton or the False singleton.
* bpo-43690: stable_abi.py no longer parses macros (GH-25136)Victor Stinner2021-04-011-1/+0
| | | | | | | | The stable_abi.py script no longer parse macros. Macro targets can be static inline functions which are not part of the stable ABI, only part of the limited C API. Run "make regen-limited-abi" to exclude PyType_HasFeature from Doc/data/stable_abi.dat.

* bpo-43244: Remove symtable.h header file (GH-24910)Victor Stinner2021-03-191-1/+0
| | | | | | | | | | | | | | | | | | Rename Include/symtable.h to to Include/internal/pycore_symtable.h, don't export symbols anymore (replace PyAPI_FUNC and PyAPI_DATA with extern) and rename functions: * PyST_GetScope() to _PyST_GetScope() * PySymtable_BuildObject() to _PySymtable_Build() * PySymtable_Free() to _PySymtable_Free() Remove PySymtable_Build(), Py_SymtableString() and Py_SymtableStringObject() functions. The Py_SymtableString() function was part the stable ABI by mistake but it could not be used, since the symtable.h header file was excluded from the limited C API. The Python symtable module remains available and is unchanged.
* bpo-43356: Allow passing a signal number to interrupt_main() (GH-24755)Antoine Pitrou2021-03-111-0/+2

* bpo-41756: Introduce PyGen_Send C API (GH-22196)Vladimir Matveev2020-09-191-0/+5
| | | | | | | | | | | | | The new API allows to efficiently send values into native generators and coroutines avoiding use of StopIteration exceptions to signal returns. ceval loop now uses this method instead of the old "private" _PyGen_Send C API. This translates to 1.6x increased performance of 'await' calls in micro-benchmarks. Aside from CPython core improvements, this new API will also allow Cython to generate more efficient code, benefiting high-performance IO libraries like uvloop.

* bpo-38858: new_interpreter() reuses pycore_init_builtins() (GH-17351)Victor Stinner2019-11-221-2/+0
| | | | | | | | | 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.

* Issue #24400: Introduce a distinct type for 'async def' coroutines.Yury Selivanov2015-06-221-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary of changes: 1. Coroutines now have a distinct, separate from generators type at the C level: PyGen_Type, and a new typedef PyCoroObject. PyCoroObject shares the initial segment of struct layout with PyGenObject, making it possible to reuse existing generators machinery. The new type is exposed as 'types.CoroutineType'. As a consequence of having a new type, CO_GENERATOR flag is no longer applied to coroutines. 2. Having a separate type for coroutines made it possible to add an __await__ method to the type. Although it is not used by the interpreter (see details on that below), it makes coroutines naturally (without using __instancecheck__) conform to collections.abc.Coroutine and collections.abc.Awaitable ABCs. [The __instancecheck__ is still used for generator-based coroutines, as we don't want to add __await__ for generators.] 3. Add new opcode: GET_YIELD_FROM_ITER. The opcode is needed to allow passing native coroutines to the YIELD_FROM opcode. Before this change, 'yield from o' expression was compiled to: (o) GET_ITER LOAD_CONST YIELD_FROM Now, we use GET_YIELD_FROM_ITER instead of GET_ITER. The reason for adding a new opcode is that GET_ITER is used in some contexts (such as 'for .. in' loops) where passing a coroutine object is invalid. 4. Add two new introspection functions to the inspec module: getcoroutinestate(c) and getcoroutinelocals(c). 5. inspect.iscoroutine(o) is updated to test if 'o' is a native coroutine object. Before this commit it used abc.Coroutine, and it was requested to update inspect.isgenerator(o) to use abc.Generator; it was decided, however, that inspect functions should really be tailored for checking for native types. 6. sys.set_coroutine_wrapper(w) API is updated to work with only native coroutines. Since types.coroutine decorator supports any type of callables now, it would be confusing that it does not work for all types of coroutines. 7. Exceptions logic in generators C implementation was updated to raise clearer messages for coroutines: Before: TypeError("generator raised StopIteration") After: TypeError("coroutine raised StopIteration")
