* gh-63760: Don't declare gethostname() on Solaris (#108817)Victor Stinner2023-09-021-5/+0
| | | | | | | | | | | | | Since 2005, Solaris defines gethostname(). socketmodule.c no longer has to define gethostname() for Solaris. Oracle Solaris and OpenSolaris have patches to remove the gethostname() definition in Python: * https://github.com/oracle/solaris-userland/blob/master/components/python/python37/patches/15-gethostname.patch * https://github.com/OpenIndiana/oi-userland/blob/oi/hipster/components/python/python37/patches/15-gethostname.patch * https://github.com/omniosorg/omnios-build/blob/master/build/python27/patches/24-gethostname.patch Co-authored-by: Jakub Kulík <Kulikjak@gmail.com>

|
* gh-108765: Remove old prototypes from pyport.h (#108782)Victor Stinner2023-09-021-1/+5
| | | | | | | Move prototypes of gethostname(), _getpty() and struct termios from pyport.h to the C code using them: posixmodule.c, socketmodule.c and termios.c. Replace "#ifdef SOLARIS" with "#ifdef __sun".
* gh-108240: Add pycore_capsule.h internal header file (#108596)Victor Stinner2023-08-291-0/+1
| | | | Move _PyCapsule_SetTraverse() definition to a new internal header file: pycore_capsule.h.
* gh-107913: Fix possible losses of OSError error codes (GH-107930)Serhiy Storchaka2023-08-261-5/+7
| | | | | | Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be called immediately after using the C API which sets errno or the Windows error code.
* gh-108444: Replace _PyLong_AsInt() with PyLong_AsInt() (#108459)Victor Stinner2023-08-241-4/+4
| | | | | | Change generated by the command: sed -i -e 's!_PyLong_AsInt!PyLong_AsInt!g' \ $(find -name "*.c" -o -name "*.h")
* gh-106320: Remove private _PyDict functions (#108449)Victor Stinner2023-08-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Move private functions to the internal C API (pycore_dict.h): * _PyDictView_Intersect() * _PyDictView_New() * _PyDict_ContainsId() * _PyDict_DelItemId() * _PyDict_DelItem_KnownHash() * _PyDict_GetItemIdWithError() * _PyDict_GetItem_KnownHash() * _PyDict_HasSplitTable() * _PyDict_NewPresized() * _PyDict_Next() * _PyDict_Pop() * _PyDict_SetItemId() * _PyDict_SetItem_KnownHash() * _PyDict_SizeOf() No longer export most of these functions. Move also the _PyDictViewObject structure to the internal C API. Move dict_getitem_knownhash() function from _testcapi to the _testinternalcapi extension. Update test_capi.test_dict for this change.
* gh-108240: Add _PyCapsule_SetTraverse() internal function (#108339)Victor Stinner2023-08-231-6/+31
| | | | | The _socket extension uses _PyCapsule_SetTraverse() to visit and clear the socket type in the garbage collector. So the _socket.socket type can be cleared in some corner cases when it wasn't possible before.
* gh-104432: Use `memcpy()` to avoid misaligned loads (#104433)Christopher Chavez2023-07-271-5/+17
| | | | | Fix potential unaligned memory access on C APIs involving returned sequences of `char *` pointers within the :mod:`grp` and :mod:`socket` modules. These were revealed using a ``-fsaniziter=alignment`` build on ARM macOS.
* gh-106869: Use new PyMemberDef constant names (#106871)Victor Stinner2023-07-251-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove '#include "structmember.h"'. * If needed, add <stddef.h> to get offsetof() function. * Update Parser/asdl_c.py to regenerate Python/Python-ast.c. * Replace: * T_SHORT => Py_T_SHORT * T_INT => Py_T_INT * T_LONG => Py_T_LONG * T_FLOAT => Py_T_FLOAT * T_DOUBLE => Py_T_DOUBLE * T_STRING => Py_T_STRING * T_OBJECT => _Py_T_OBJECT * T_CHAR => Py_T_CHAR * T_BYTE => Py_T_BYTE * T_UBYTE => Py_T_UBYTE * T_USHORT => Py_T_USHORT * T_UINT => Py_T_UINT * T_ULONG => Py_T_ULONG * T_STRING_INPLACE => Py_T_STRING_INPLACE * T_BOOL => Py_T_BOOL * T_OBJECT_EX => Py_T_OBJECT_EX * T_LONGLONG => Py_T_LONGLONG * T_ULONGLONG => Py_T_ULONGLONG * T_PYSSIZET => Py_T_PYSSIZET * T_NONE => _Py_T_NONE * READONLY => Py_READONLY * PY_AUDIT_READ => Py_AUDIT_READ * READ_RESTRICTED => Py_AUDIT_READ * PY_WRITE_RESTRICTED => _Py_WRITE_RESTRICTED * RESTRICTED => (READ_RESTRICTED | _Py_WRITE_RESTRICTED)

* gh-92536: Remove PyUnicode_READY() calls (#105210)Victor Stinner2023-06-011-3/+0
| | | | Since Python 3.12, PyUnicode_READY() does nothing and always returns 0.
* gh-98836: Extend PyUnicode_FromFormat() (GH-98838)Serhiy Storchaka2023-05-211-6/+2
| | | | | | | | | * Support for conversion specifiers o (octal) and X (uppercase hexadecimal). * Support for length modifiers j (intmax_t) and t (ptrdiff_t). * Length modifiers are now applied to all integer conversions. * Support for wchar_t C strings (%ls and %lV). * Support for variable width and precision (*). * Support for flag - (left alignment).
* GH-104308: socket.getnameinfo should release the GIL (#104307)Nathaniel J. Smith2023-05-081-0/+2

* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).

* gh-102255: Use GetVersionEx instead of GetVersionExW to match argument type ↵Max Bachmann2023-03-201-1/+1
| | | | | | (GH-102583) Since we pass a structure of type `OSVERSIONINFOEX`, we need to call `GetVersionEx` instead of `GetVersionExW`.
* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-21/+39
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.

* gh-74895: getaddrinfo no longer raises OverflowError (#2435)Radek Smejkal2023-02-141-5/+9
| | | `socket.getaddrinfo()` no longer raises `OverflowError` based on the **port** argument. Error reporting (or not) for its value is left up to the underlying C library `getaddrinfo()` implementation.
* gh-100795: Don't call freeaddrinfo on failure. (#101252)Gregory P. Smith2023-01-231-0/+4
| | | | | | | | | When getaddrinfo returns an error, the output pointer is in an unknown state Don't call freeaddrinfo on it. See the issue for discussion and details with links to reasoning. _Most_ libc getaddrinfo implementations never modify the output pointer unless they are returning success. Co-authored-by: Sergey G.

* gh-98030: socket: add missing TCP socket options (#98031)Matthieu Baerts2022-12-081-3/+63
| | | | | | | | | | | | | A few TCP socket options have been added to the Linux kernel these last few years. This commit adds all the ones available in Linux 6.0: https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91 While at it, the TCP_FASTOPEN option has been moved lower in the list just to keep the same order as in tcp.h to ease future synchronisations.

* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-031-2/+2
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* gh-99300: Use Py_NewRef() in Modules/ directory (#99469)Victor Stinner2022-11-141-18/+8
