* bpo-33106: change dbm key deletion error for readonly file from KeyError to ↵Xiang Zhang2018-12-122-5/+19
| | | | | | dbm.error (#6295)
* bpo-35454: Fix miscellaneous minor issues in error handling. (#11077)Serhiy Storchaka2018-12-113-8/+17
| | | | | | * bpo-35454: Fix miscellaneous minor issues in error handling. * Fix a null pointer dereference.
* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-113-8/+6
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-31374: expat doesn't include <pyconfig.h> on Windows (GH-11079)Victor Stinner2018-12-101-1/+3
|
* bpo-32788: Better error handling in sqlite3. (GH-3723)Serhiy Storchaka2018-12-105-121/+128
| | | Propagate unexpected errors (like MemoryError and KeyboardInterrupt) to user.
* bpo-31374: Include pyconfig.h earlier in expat (GH-11064)Victor Stinner2018-12-101-0/+1
| | | | | | Include <pyconfig.h> ealier in Modules/expat/xmltok.c to define properly _POSIX_C_SOURCE. Python defines _POSIX_C_SOURCE as 200809L, whereas <features.h> (included indirectly by <string.h>) defines _POSIX_C_SOURCE as 199506L.
* bpo-35050: AF_ALG length check off-by-one error (GH-10058)Christian Heimes2018-12-101-3/+5
| | | | | | | | The length check for AF_ALG salg_name and salg_type had a off-by-one error. The code assumed that both values are not necessarily NULL terminated. However the Kernel code for alg_bind() ensures that the last byte of both strings are NULL terminated. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-35445: Do not ignore memory errors when create posix.environ. (GH-11049)Serhiy Storchaka2018-12-101-37/+27
|
* Remove a duplicate descriptor in gdbm. (GH-11053)Serhiy Storchaka2018-12-091-1/+0
|
* bpo-35441: Remove dead and buggy code related to PyList_SetItem(). (GH-11033)Zackery Spytz2018-12-084-24/+15
| | | | | | | | | | In _localemodule.c and selectmodule.c, remove dead code that would cause double decrefs if run. In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases where a new list is populated and there is no possibility of an error. In addition, check if the list changed size in the loop in array_array_fromlist().
* bpo-22005: Fix condition for unpickling a date object. (GH-11025)Serhiy Storchaka2018-12-071-1/+1
|
* bpo-22005: Fixed unpickling instances of datetime classes pickled by Python ↵Serhiy Storchaka2018-12-071-91/+174
| | | | | | 2. (GH-11017) encoding='latin1' should be used for successful decoding.
* bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. ↵Zackery Spytz2018-12-078-15/+43
| | | | | | (GH-11015) Set MemoryError when appropriate, add missing failure checks, and fix some potential leaks.
* bpo-35384: The repr of ctypes.CArgObject no longer fails for non-ascii ↵Serhiy Storchaka2018-12-061-4/+22
| | | | character. (GH-10863)
* bpo-35310: Clear select() lists before returning upon EINTR (GH-10877)Oran Avraham2018-12-051-0/+4
| | | | | | select() calls are retried on EINTR (per PEP 475). However, if a timeout was provided and the deadline has passed after running the signal handlers, rlist, wlist and xlist should be cleared since select(2) left them unmodified.
* bpo-34604: Use %R because of invisible characters or trailing whitespaces. ↵William Grzybowski2018-12-052-2/+2
| | | | (GH-9165)
* bpo-34987: Fix a possible null pointer dereference in _pickle.c's ↵Zackery Spytz2018-12-051-1/+4
| | | | save_reduce(). (GH-9886)
* bpo-34052: Prevent SQLite functions from setting callbacks on exceptions. ↵Sergey Fedoseev2018-12-051-18/+13
| | | | (GH-8113)
* bpo-32787: Better error handling in ctypes. (#3727)Serhiy Storchaka2018-12-055-112/+247
| | | | | | | | | | | | * bpo-31572: Get rid of PyObject_HasAttrString() in ctypes. * Fix error handling for _pack_. * Don't silence errors when look up in a dict. * Use _PyObject_LookupAttrId(). * More changes.
* bpo-35373: Fix PyInit_time() error handling (GH-10865)Victor Stinner2018-12-031-4/+7
| | | | | | | * PyInit_time() now returns NULL if an exception is raised. * Rename PyInit_timezone() to init_timezone(). "PyInit_" prefix is a special prefix for function initializing a module. init_timezone() doesn't initialize a module and the function is not exported.
* bpo-35373: Fix PyInit_timezone() if HAVE_DECL_TZNAME is defined (GH-10861)Victor Stinner2018-12-031-4/+5
| | | If HAVE_DECL_TZNAME, PyInit_timezone() now returns -1 on error.
* bpo-10320: Replace nonstandard sprintf() length modifier in ctypes' ↵Zackery Spytz2018-12-031-1/+1
| | | | | PyCArg_repr(). (GH-10853) Use "ll" instead of the nonstandard "q".
* bpo-35371: Fix possible crash in os.utime() on Windows. (GH-10844)Serhiy Storchaka2018-12-011-22/+15
|
* get_gmtoff() now returns time_t (GH-10838)Victor Stinner2018-11-301-11/+36
| | | | | | | get_gmtoff() now returns time_t instead of int to fix the following Visual Studio warning: Modules\timemodule.c(1183): warning C4244: 'return': conversion from 'time_t' to 'int', possible loss of data
* Fix compiler warning in call_readline() (GH-10820)Victor Stinner2018-11-301-3/+3
| | | | | | | | | | | | | | Replace strncpy() with memcpy() in call_readline() to fix the following warning, the NUL byte is written manually just after: Modules/readline.c: In function ‘call_readline’: Modules/readline.c:1303:9: warning: ‘strncpy’ output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation] strncpy(p, q, n); ^~~~~~~~~~~~~~~~ Modules/readline.c:1279:9: note: length computed here n = strlen(p); ^~~~~~~~~
* bpo-35356: Fix a possible reference leak in nis.maps(). (GH-10808)Zackery Spytz2018-11-301-0/+1
|
* bpo-35337: Fix gettmarg(): use PyStructSequence_GET_ITEM() (GH-10765)Victor Stinner2018-11-281-2/+2
| | | | PyStructSequence_GET_ITEM() must be used instead of PyTuple_GET_ITEM() on a StructTimeType.
* bpo-33029: Fix signatures of getter and setter functions. (GH-10746)Serhiy Storchaka2018-11-2716-68/+68
| | | Fix also return type for few other functions (clear, releasebuffer).
* bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)Serhiy Storchaka2018-11-2727-136/+136
| | | | | | Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS excluding Argument Clinic generated code.
* bpo-33012: Fix signatures of METH_NOARGS funstions. (GH-10736)Serhiy Storchaka2018-11-273-12/+12
|
* bpo-33012: Fix invalid function cast warnings with gcc 8 in Argument Clinic. ↵Serhiy Storchaka2018-11-2756-516/+841
| | | | | | | | (GH-6748) Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS in Argument Clinic generated code.
* closes bpo-34212: Build core extension modules with Py_BUILD_CORE_BUILTIN. ↵E. M. Bray2018-11-271-1/+1
| | | | (GH-8712)
* bpo-35081: Add Include/internal/pycore_tupleobject.h (GH-10705)Victor Stinner2018-11-251-1/+1
| | | | Move _PyTuple_ITEMS() to a new header file: Include/internal/pycore_tupleobject.h
* bpo-35303: Fix a reference leak in _operator.c's methodcaller_repr(). (GH-10689)Zackery Spytz2018-11-231-0/+1
|
* bpo-35189: Retry fnctl calls on EINTR (GH-10413)nierob2018-11-231-23/+32
| | | | Modify the following fnctl function to retry if interrupted by a signal (EINTR): flock, lockf, fnctl.
* bpo-35177, Python-ast.h: Fix "Yield" compiler warning (GH-10664)Victor Stinner2018-11-221-0/+1
| | | | | | | | Partially revert commit 5f2df88b63e50d23914e97ec778861a52abdeaad: add "#undef Yield" to .c files after including Python-ast.h. Fix the warning: winbase.h(102): warning C4005: 'Yield': macro redefinition
* bpo-24658: os.read() reuses _PY_READ_MAX (GH-10657)Victor Stinner2018-11-221-5/+1
| | | | | os_read_impl() now also truncates the size to _PY_READ_MAX on macOS, to avoid to allocate a larger buffer even if _Py_read() is limited to _PY_READ_MAX bytes (ex: INT_MAX on macOS).
* bpo-9566: Fix compiler warnings in pyexpat.c (GH-10654)Victor Stinner2018-11-221-2/+4
| | | | | | | | | | Explicit cast a pointer difference (intptr_t) to int to fix two warnings on 64-bit Windows: Modules\pyexpat.c(1181): warning C4244: 'initializing': conversion from '__int64' to 'int', possible loss of data Modules\pyexpat.c(1192): warning C4244: 'initializing': conversion from '__int64' to 'int', possible loss of data

| | | | | | | | | Fixed the following compiler warning in multibytecodec.c: warning C4244: '=': conversion from 'Py_ssize_t' to 'unsigned char', possible loss of data Cast Py_ssize_t to unsigned char: the maximum value is checked on the previous line.
* bpo-35059: Cast void* to PyObject* (GH-10650)Victor Stinner2018-11-222-5/+7
| | | Don't pass void* to Python macros: use _PyObject_CAST().
* bpo-35059: Cleanup usage of Python macros (GH-10648)Victor Stinner2018-11-223-89/+112
| | | | | | | | | | | | | Don't pass complex expressions but regular variables to Python macros. * _datetimemodule.c: split single large "if" into two "if" in date_new(), time_new() and datetime_new(). * _pickle.c, load_extension(): flatten complex "if" expression into more regular C code. * _ssl.c: addbool() now uses a temporary bool_obj to only evaluate the value once. * weakrefobject.c: replace "Py_INCREF(result = proxy);" with "result = proxy; Py_INCREF(result);"
* bpo-35059: Convert _PyObject_GC_TRACK() to inline function (GH-10643)Victor Stinner2018-11-221-6/+7
| | | | | | | | | | | | | * Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG() macros. * PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(), instead of Py_FatalError(), if the object is already tracked, to dump more information on error. * _PyObject_GC_TRACK() no longer checks if the object is already tracked at runtime, use an assertion instead for best performances; PyObject_GC_Track() still checks at runtime. * pycore_object.h now includes pycore_pystate.h. * Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to inline functions.
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-218-1/+9
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-25750: Fix a compiler warning introduced in GH-9084. (GH-10234)Serhiy Storchaka2018-11-201-5/+5
|
* bpo-35021: Fix assertion failures in _datetimemodule.c. (GH-10039)Serhiy Storchaka2018-11-201-48/+51
| | | | | | | | Fixes assertion failures in _datetimemodule.c introduced in the previous fix (see bpo-31752). Rather of trying to handle an int subclass as exact int, let it to use overridden special methods, but check the result of divmod().
* bpo-28604: Fix localeconv() for different LC_MONETARY (GH-10606)Victor Stinner2018-11-202-17/+94
| | | | | | | | | | | | | | | | | | | | | locale.localeconv() now sets temporarily the LC_CTYPE locale to the LC_MONETARY locale if the two locales are different and monetary strings are non-ASCII. This temporary change affects other threads. Changes: * locale.localeconv() can now set LC_CTYPE to LC_MONETARY to decode monetary fields. * Add LocaleInfo.grouping_buffer: copy localeconv() grouping string since it can be replaced anytime if a different thread calls localeconv(). * _Py_GetLocaleconvNumeric() now requires a "struct lconv *" structure, so locale.localeconv() now longer calls localeconv() twice. Moreover, the function now requires all arguments to be non-NULL. * Rename STATIC_LOCALE_INFO_INIT to LocaleInfo_STATIC_INIT. * Move _Py_GetLocaleconvNumeric() definition from fileutils.h to pycore_fileutils.h. pycore_fileutils.h now includes locale.h. * The _locale module is now built with Py_BUILD_CORE defined.
* Fix a possible reference leak in _socket.getaddrinfo(). (GH-10543)Zackery Spytz2018-11-141-2/+4
| | | "single" needs to be decrefed if PyList_Append() fails.
* bpo-35233: InitConfigTests tests more config vars (GH-10541)Victor Stinner2018-11-141-35/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | test_embed.InitConfigTests tests more configuration variables. Changes: * InitConfigTests tests more core configuration variables: * base_exec_prefix * base_prefix * exec_prefix * home * legacy_windows_fs_encoding * legacy_windows_stdio * module_search_path_env * prefix * "_testembed init_from_config" tests more variables: * argv * warnoptions * xoptions * InitConfigTests: add check_global_config(), check_core_config() and check_main_config() subfunctions to cleanup the code. Move also constants at the class level (ex: COPY_MAIN_CONFIG). * Fix _PyCoreConfig_AsDict(): don't set stdio_encoding twice * Use more macros in _PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict() to reduce code duplication. * Other minor cleanups.
* bpo-35233: Rewrite test_embed.InitConfigTests (GH-10524)Victor Stinner2018-11-131-4/+12
| | | | | | | | | | | | * Fix _PyCoreConfig_SetGlobalConfig(): set also Py_FrozenFlag * Fix _PyCoreConfig_AsDict(): export also xoptions * Add _Py_GetGlobalVariablesAsDict() and _testcapi.get_global_config() * test.pythoninfo: dump also global configuration variables * _testembed now serializes global, core and main configurations using JSON to reuse _Py_GetGlobalVariablesAsDict(), _PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict(), rather than duplicating code. * test_embed.InitConfigTests now test much more configuration variables
* bpo-35233: Fix _PyMainInterpreterConfig_Copy() (GH-10519)Victor Stinner2018-11-132-14/+81
| | | | | | | | * Fix _PyMainInterpreterConfig_Copy(): copy 'install_signal_handlers' attribute * Add _PyMainInterpreterConfig_AsDict() * Add unit tests on the main interpreter configuration to test_embed.InitConfigTests * test.pythoninfo: log also main_config
