* bpo-36301: Add _Py_GetConfigsAsDict() function (GH-12540)Victor Stinner2019-03-251-23/+3
| | | | | | | * Add _Py_GetConfigsAsDict() function to get all configurations as a dict. * dump_config() of _testembed.c now dumps preconfig as a separated key: call _Py_GetConfigsAsDict(). * Make _PyMainInterpreterConfig_AsDict() private.
* bpo-36301: Cleanup preconfig code (GH-12535)Victor Stinner2019-03-251-18/+23
| | | | | | | | | | | | | | | Prepare code to move some _PyPreConfig parameters into _PyPreCmdline. Changes: * _PyCoreConfig_ReadFromArgv(): remove preconfig parameter, use _PyRuntime.preconfig. * Add _PyPreCmdline_GetPreConfig() (called by _PyPreConfig_Read()). * Rename _PyPreCmdline_Init() to _PyPreCmdline_SetArgv() * Factorize _Py_PreInitializeFromPreConfig() code: add pyinit_preinit(). * _PyPreConfig_Read() now sets coerce_c_locale to 2 if it must be coerced. * Remove _PyCoreConfig_ReadPreConfig(). * _PyCoreConfig_Write() now copies updated preconfig into _PyRuntime.
* bpo-36421: Fix a possible double decref in _ctypes.c's PyCArrayType_new(). ↵Zackery Spytz2019-03-251-0/+1
| | | | | | | (GH-12530) Set type_attr to NULL after the assignment to stgdict->proto (like what is done with stgdict after the Py_SETREF() call) so that it is not decrefed twice on error.
* asyncio: PendingDeprecationWarning -> DeprecationWarning (GH-12494)Inada Naoki2019-03-221-2/+2
| | | `Task.current_task()` and `Task.all_tasks()` will be removed in 3.9.
* bpo-36256: Fix bug in parsermodule when parsing if statements (GH-12477)Pablo Galindo2019-03-211-5/+17
| | | | | | bpo-36256: Fix bug in parsermodule when parsing if statements In the parser module, when validating nodes before starting the parsing with to create a ST in "parser_newstobject" there is a problem that appears when two arcs in the same DFA state has transitions with labels with the same type. For example, the DFA for if_stmt has a state with two labels with the same type: "elif" and "else" (type NAME). The algorithm tries one by one the arcs until the label that starts the arc transition has a label with the same type of the current child label we are trying to accept. In this case, the arc for "elif" comes before the arc for "else"and passes this test (because the current child label is "else" and has the same type as "elif"). This lead to expecting a namedexpr_test (305) instead of a colon (11). The solution is to compare also the string representation (in case there is one) of the labels to see if the transition that we have is the correct one.

* bpo-8677: use PY_SSIZE_T_CLEAN in socketmodule.c (GH-12467)Inada Naoki2019-03-201-1/+2
|
* bpo-8677: use PY_SSIZE_T_CLEAN in Modules/_gdbmodule.c (GH-12464)Inada Naoki2019-03-201-9/+27
|
* bpo-36301: Add _PyRuntime.pre_initialized (GH-12457)Victor Stinner2019-03-201-19/+10
| | | | | | | | | * Add _PyRuntime.pre_initialized: set to 1 when Python is pre-initialized * Add _Py_PreInitialize() and _Py_PreInitializeFromPreConfig(). * _PyCoreConfig_Read() now calls _Py_PreInitialize(). * Move _PyPreConfig_GetGlobalConfig() and _PyCoreConfig_GetGlobalConfig() calls from main.c to preconfig.c and coreconfig.c.
* bpo-36236: Handle removed cwd at Python init (GH-12424)Victor Stinner2019-03-191-9/+11
| | | | | | | | At Python initialization, the current directory is no longer prepended to sys.path if it has been removed. Rename _PyPathConfig_ComputeArgv0() to _PyPathConfig_ComputeSysPath0() to avoid confusion between argv[0] and sys.path[0].
* bpo-36356: pymain_free() calls _PyRuntime_Finalize() (GH-12435)Victor Stinner2019-03-191-0/+1
| | | | Ensure that _PyRuntime_Finalize() is always call. This change fix a few memory leaks when running "python3 -V".
* bpo-36356: Release Unicode interned strings on Valgrind (#12431)Victor Stinner2019-03-191-12/+0
| | | | | | | | | | | When Python is compiled with Valgrind support, release Unicode interned strings at exit in _PyUnicode_Fini(). * Rename _Py_ReleaseInternedUnicodeStrings() to unicode_release_interned() and make it private. * unicode_release_interned() is now called from _PyUnicode_Fini(): it must be called with a running Python thread state for TRASHCAN, it cannot be called from pymain_free(). * Don't display statistics on interned strings at exit anymore
* bpo-8677: use PY_SSIZE_T_CLEAN in sqlite (GH-12434)Inada Naoki2019-03-199-0/+9
| | | | Modules/_sqlite/cursor.c uses "y#" format. It didn't declare PY_SSIZE_T_CLEAN, but the argument is Py_ssize_t already.
* bpo-36352: Avoid hardcoded MAXPATHLEN size in getpath.c (GH-12423)Victor Stinner2019-03-191-150/+234
| | | | * Use Py_ARRAY_LENGTH() rather than hardcoded MAXPATHLEN in getpath.c. * Pass string length to functions modifying strings.
* bpo-36301: Error if decoding pybuilddir.txt fails (GH-12422)Victor Stinner2019-03-191-12/+16
| | | | | | | | Python initialization now fails if decoding pybuilddir.txt configuration file fails at startup. _PyPathConfig_Calculate() now reports memory allocation failure and decoding error on decoding pybuilddir.txt content from UTF-8/surrogateescape.
* bpo-36352: Add error handling to getpath.c (GH-12421)Victor Stinner2019-03-181-69/+233
| | | | Replace Py_FatalError() with _PyInitError to let the caller handle the fatal error.
* bpo-36301: Fix Py_Main() memory leaks (GH-12420)Victor Stinner2019-03-181-2/+6
| | | | | | | | | | bpo-36301, bpo-36333: * Fix memory allocator used by _PyPathConfig_ClearGlobal(): force the default allocator. * _PyPreConfig_ReadFromArgv(): free init_ctype_locale memory. * pymain_main(): call pymain_free() on init error Co-Authored-By: Stéphane Wirtel <stephane@wirtel.be>

* bpo-36301: Add _PyWstrList structure (GH-12343)Victor Stinner2019-03-151-15/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace messy _Py_wstrlist_xxx() functions with a new clean _PyWstrList structure and new _PyWstrList_xxx() functions. Changes: * Add _PyCoreConfig.use_module_search_paths to decide if _PyCoreConfig.module_search_paths should be computed or not, to support empty search path list. * _PyWstrList_Clear() sets length to 0 and items to NULL, whereas _Py_wstrlist_clear() only freed memory. * _PyWstrList_Append() returns an int, whereas _Py_wstrlist_append() returned _PyInitError. * _PyWstrList uses Py_ssize_t for the length, instead of int. * Replace (int, wchar_t**) with _PyWstrList in: * _PyPreConfig * _PyCoreConfig * _PyPreCmdline * _PyCmdline * Replace "int orig_argv; wchar_t **orig_argv;" with "_PyWstrList orig_argv". * _PyCmdline and _PyPreCmdline now also copy wchar_argv. * Rename _PyArgv_Decode() to _PyArgv_AsWstrList(). * PySys_SetArgvEx() now pass the fixed (argc, argv) to _PyPathConfig_ComputeArgv0() (don't pass negative argc or NULL argv). * _PyOS_GetOpt() uses Py_ssize_t
* bpo-36127: Argument Clinic: inline parsing code for keyword parameters. ↵Serhiy Storchaka2019-03-1439-606/+4761

* Rework integer overflow path in math.prod and add more tests (GH-11809)Pablo Galindo2019-03-091-5/+51
| | | | | The overflow check was relying on undefined behaviour as it was using the result of the multiplication to do the check, and once the overflow has already happened, any operation on the result is undefined behaviour. Some extra checks that exercise code paths related to this are also added.
* Remove d_initial from the parser as it is unused (GH-12212)tyomitch2019-03-091-1/+1
| | | d_initial, the first state of a particular DFA in the parser has always been initialized to 0 in the old pgen as well as the new pgen. As this value is not used and the first state of each DFA is assumed to be the first element in the array representing it, remove d_initial from the parser to reduce complexity.
* bpo-33608: Make sure locks in the runtime are properly re-created. (gh-12245)Eric Snow2019-03-081-0/+1
|
* bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)Guido van Rossum2019-03-072-2/+5
| | | | | | | This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.) https://bugs.python.org/issue35975

* bpo-36142: Add _PyPreConfig_SetAllocator() (GH-12187)Victor Stinner2019-03-061-23/+2
| | | | | | | | | | | * _PyPreConfig_Write() now reallocates the pre-configuration with the new memory allocator. * It is no longer needed to force the "default raw memory allocator" to clear pre-configuration and core configuration. Simplify the code. * _PyPreConfig_Write() now does nothing if called after Py_Initialize(): no longer check if the allocator is the same. * Remove _PyMem_GetDebugAllocatorsName(): dev mode sets again allocator to "debug".
* bpo-36142: _PyPreConfig_Write() sets the allocator (GH-12186)Victor Stinner2019-03-061-2/+1
| | | | | | | * _PyPreConfig_Write() now sets the memory allocator. * _PyPreConfig_Write() gets a return type: _PyInitError. * _Py_InitializeCore() now reads and writes the pre-configuration (set the memory allocator, configure the locale) before reading and writing the core configuration.
* Fix the C function signature for _collections._tuplegetter.__reduce__. ↵Serhiy Storchaka2019-03-051-2/+2

* bpo-36142: Add _PyPreConfig_ReadFromArgv() (GH-12173)Victor Stinner2019-03-051-7/+33
| | | | The new function is now responsible to parse -E and -I command line arguments.
* bpo-36142: Add _PyPreConfig structure (GH-12172)Victor Stinner2019-03-051-2/+2
