* bpo-38530: Offer suggestions on AttributeError (#16856)Pablo Galindo2021-04-141-1/+11
| | | | | | | | | When printing AttributeError, PyErr_Display will offer suggestions of similar attribute names in the object that the exception was raised from: >>> collections.namedtoplo Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: module 'collections' has no attribute 'namedtoplo'. Did you mean: namedtuple?
* bpo-43244: Remove Yield macro from pycore_ast.h (GH-25243)Victor Stinner2021-04-071-2/+0
| | | | | | | | * pycore_ast.h no longer defines the Yield macro. * Fix a compiler warning on Windows: "warning C4005: 'Yield': macro redefinition". * Python-ast.c now defines directly functions with their real _Py_xxx() name, rather than xxx(). * Remove "#undef Yield" in C files including pycore_ast.h.

* bpo-43244: Remove the pyarena.h header (GH-25007)Victor Stinner2021-03-241-12/+12
| | | | | | | | | | | | | | | | | | Remove the pyarena.h header file with functions: * PyArena_New() * PyArena_Free() * PyArena_Malloc() * PyArena_AddPyObject() These functions were undocumented, excluded from the limited C API, and were only used internally by the compiler. Add pycore_pyarena.h header. Rename functions: * PyArena_New() => _PyArena_New() * PyArena_Free() => _PyArena_Free() * PyArena_Malloc() => _PyArena_Malloc() * PyArena_AddPyObject() => _PyArena_AddPyObject()
* bpo-43244: Remove parser_interface.h header file (GH-25001)Victor Stinner2021-03-241-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Remove parser functions using the "struct _mod" type, because the AST C API was removed: * PyParser_ASTFromFile() * PyParser_ASTFromFileObject() * PyParser_ASTFromFilename() * PyParser_ASTFromString() * PyParser_ASTFromStringObject() These functions were undocumented and excluded from the limited C API. Add pycore_parser.h internal header file. Rename functions: * PyParser_ASTFromFileObject() => _PyParser_ASTFromFile() * PyParser_ASTFromStringObject() => _PyParser_ASTFromString() These functions are no longer exported (replace PyAPI_FUNC() with extern). Remove also _PyPegen_run_parser_from_file() function. Update test_peg_generator to use _PyPegen_run_parser_from_file_pointer() instead.
* bpo-43244: Add pycore_compile.h header file (GH-25000)Victor Stinner2021-03-231-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the compiler functions using "struct _mod" type, because the public AST C API was removed: * PyAST_Compile() * PyAST_CompileEx() * PyAST_CompileObject() * PyFuture_FromAST() * PyFuture_FromASTObject() These functions were undocumented and excluded from the limited C API. Rename functions: * PyAST_CompileObject() => _PyAST_Compile() * PyFuture_FromASTObject() => _PyFuture_FromAST() Moreover, _PyFuture_FromAST() is no longer exported (replace PyAPI_FUNC() with extern). _PyAST_Compile() remains exported for test_peg_generator. Remove also compatibility functions: * PyAST_Compile() * PyAST_CompileEx() * PyFuture_FromAST()
* bpo-43244: Remove ast.h, asdl.h, Python-ast.h headers (GH-24933)Victor Stinner2021-03-231-1/+1
| | | | | | | | | | | | | | | | These functions were undocumented and excluded from the limited C API. Most names defined by these header files were not prefixed by "Py" and so could create names conflicts. For example, Python-ast.h defined a "Yield" macro which was conflict with the "Yield" name used by the Windows <winbase.h> header. Use the Python ast module instead. * Move Include/asdl.h to Include/internal/pycore_asdl.h. * Move Include/Python-ast.h to Include/internal/pycore_ast.h. * Remove ast.h header file. * pycore_symtable.h no longer includes Python-ast.h.
* bpo-43244: Remove symtable.h header file (GH-24910)Victor Stinner2021-03-191-43/+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-35134: Move non-limited C API files to Include/cpython/ (GH-24561)Nicholas Sim2021-02-191-2/+0
| | | | | | Include/{odictobject.h,parser_interface.h,picklebufobject.h,pydebug.h,pyfpe.h} into Include/cpython/. Parser: peg_api: include Python.h instead of parser_interface.h.
* bpo-32381: Add _PyRun_AnyFileObject() (GH-23723)Victor Stinner2020-12-091-26/+73
| | | | | | | | | | pymain_run_file() no longer encodes the filename: pass the filename as an object to the new _PyRun_AnyFileObject() function. Add new private functions: * _PyRun_AnyFileObject() * _PyRun_InteractiveLoopObject() * _Py_FdIsInteractive()
* bpo-32381: Add _PyRun_SimpleFileObject() (GH-23709)Victor Stinner2020-12-081-4/+4
| | | | pymain_run_startup() now pass the filename as a Python object to _PyRun_SimpleFileObject().
* bpo-32381: Fix PyRun_SimpleFileExFlags() encoding (GH-23642)Victor Stinner2020-12-081-92/+132
| | | | | | | | | | Fix encoding name when running a ".pyc" file on Windows: PyRun_SimpleFileExFlags() now uses the correct encoding to decode the filename. * Add pyrun_file() subfunction. * Add pyrun_simple_file() subfunction. * PyRun_SimpleFileExFlags() now calls _Py_fopen_obj() rather than _Py_fopen().
* bpo-40939: Restore some stable API functions incorrectly deleted (GH-23606)Pablo Galindo2020-12-021-8/+103

* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-4/+9
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
* bpo-41991: Remove _PyObject_HasAttrId (GH-22629)Serhiy Storchaka2020-10-101-2/+4
| | | It can silence arbitrary exceptions.
* bpo-40939: Rename PyPegen* functions to PyParser* (GH-21016)Lysandros Nikolaou2020-06-211-8/+8
| | | | | | Rename PyPegen* functions to PyParser*, so that we can remove the old set of PyParser* functions that were using the old parser.
* bpo-40939: Remove the old parser (Part 2) (GH-21005)Lysandros Nikolaou2020-06-201-3/+0
| | | Remove some remaining files and Makefile targets for the old parser
* bpo-40939: Remove the old parser (GH-20768)Pablo Galindo2020-06-111-471/+6
| | | This commit removes the old parser, the deprecated parser module, the old parser compatibility flags and environment variables and all associated support code and documentation.

* bpo-40612: Fix SyntaxError edge cases in traceback formatting (GH-20072)Guido van Rossum2020-05-151-19/+47
| | | | | | | | | | | | | This fixes both the traceback.py module and the C code for formatting syntax errors (in Python/pythonrun.c). They now both consistently do the following: - Suppress caret if it points left of text - Allow caret pointing just past end of line - If caret points past end of line, clip to *just* past end of line The syntax error formatting code in traceback.py was mostly rewritten; small, subtle changes were applied to the C code in pythonrun.c. There's still a difference when the text contains embedded newlines. Neither handles these very well, and I don't think the case occurs in practice. Automerge-Triggered-By: @gvanrossum
* bpo-40593: Improve syntax errors for invalid characters in source code. ↵Serhiy Storchaka2020-05-121-3/+0
| | | | (GH-20033)
* bpo-40246: Revert reporting of invalid string prefixes (GH-19888)Lysandros Nikolaou2020-05-041-3/+0
| | | | Due to backwards compatibility concerns regarding keywords immediately followed by a string without whitespace between them (like in `bg="#d00" if clear else"#fca"`) will fail to parse, commit 41d5b94af44e34ac05d4cd57460ed104ccf96628 has to be reverted.
* bpo-40334: Support CO_FUTURE_BARRY_AS_BDFL in the new parser (GH-19721)Pablo Galindo2020-04-271-2/+2
| | | This commit also allows to pass flags to the new parser in all interfaces and fixes a bug in the parser generator that was causing to inline rules with actions, making them disappear.
* bpo-40334: Improve various PEG-Parser related stuff (GH-19669)Lysandros Nikolaou2020-04-231-1/+1
| | | The changes in this commit are all related to @vstinner's original review comments of the initial PEP 617 implementation PR.
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-5/+5
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser

* bpo-40268: Remove unused imports in pylifecycle.c (GH-19533)Victor Stinner2020-04-151-21/+18
| | | | | | | | | | Remove unused imports in files: * initconfig.c * main.c * preconfig.h * pylifecycle.c * python.c * pythonrun.c
* bpo-40268: Remove unused osdefs.h includes (GH-19532)Victor Stinner2020-04-151-1/+0

* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-1/+2
|
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-1/+1
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-131-2/+2
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-40246: Report a better error message for invalid string prefixes (GH-19476)Lysandros Nikolaou2020-04-121-0/+3

* bpo-38644: Use _PySys_Audit(): pass tstate explicitly (GH-19183)Victor Stinner2020-03-271-12/+13
| | | Add the dependency to tstate more explicit.
* bpo-39947: Use _PyInterpreterState_GET_UNSAFE() (GH-18978)Victor Stinner2020-03-131-3/+3
| | | | | | | Replace _PyInterpreterState_Get() function call with _PyInterpreterState_GET_UNSAFE() macro which is more efficient but don't check if tstate or interp is NULL. _Py_GetConfigsAsDict() now uses _PyThreadState_GET().
* bpo-39542: Move object.h debug functions to internal C API (GH-18331)Victor Stinner2020-02-031-0/+1
| | | | | | | | Move the following functions from the public C API to the internal C API: * _PyDebug_PrintTotalRefs(), * _Py_PrintReferenceAddresses() * _Py_PrintReferences()
* bpo-38920: Add audit hooks for when sys.excepthook and sys.unraisable hooks ↵Steve Dower2019-11-281-0/+8

* bpo-37467: Fix PyErr_Display() for bytes filename (GH-14504)Victor Stinner2019-07-011-1/+1
| | | | | | | | | | | | | | Fix sys.excepthook() and PyErr_Display() if a filename is a bytes string. For example, for a SyntaxError exception where the filename attribute is a bytes string. Cleanup also test_sys: * Sort imports. * Rename numruns global var to INTERN_NUMRUNS. * Add DisplayHookTest and ExceptHookTest test case classes. * Don't save/restore sys.stdout and sys.displayhook using setUp()/tearDown(): do it in each test method. * Test error case (call hook with no argument) after the success case.
* bpo-37253: Add _PyCompilerFlags_INIT macro (GH-14018)Victor Stinner2019-06-131-13/+4
| | | | | Add a new _PyCompilerFlags_INIT macro to initialize PyCompilerFlags variables, rather than initializing cf_flags and cf_feature_version explicitly in each variable.
* bpo-37001: Makes symtable.symtable have parity with compile for input (#13483)Dino Viehland2019-05-281-4/+60
| | | | | | | * Makes symtable.symtable have parity for accepted datatypes for source code as compile() * Add NEWS blurb
* bpo-36829: sys.excepthook and sys.unraisablehook flush (GH-13620)Victor Stinner2019-05-281-0/+10
| | | | | | | sys.excepthook() and sys.unraisablehook() now explicitly flush the file (usually sys.stderr). If file.flush() fails, sys.excepthook() silently ignores the error, whereas sys.unraisablehook() logs the new exception.
* bpo-1230540: Add threading.excepthook() (GH-13515)Victor Stinner2019-05-271-14/+24
| | | | | | | | | | | | | | | | | | | Add a new threading.excepthook() function which handles uncaught Thread.run() exception. It can be overridden to control how uncaught exceptions are handled. threading.ExceptHookArgs is not documented on purpose: it should not be used directly. * threading.excepthook() and threading.ExceptHookArgs. * Add _PyErr_Display(): similar to PyErr_Display(), but accept a 'file' parameter. * Add _thread._excepthook(): C implementation of the exception hook calling _PyErr_Display(). * Add _thread._ExceptHookArgs: structseq type. * Add threading._invoke_excepthook_wrapper() which handles the gory details to ensure that everything remains alive during Python shutdown. * Add unit tests.
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-2/+2

| | | | | | | | | | | | | | | | * Fix a possible reference leak in _PyErr_Print() if exception is NULL. * PyErr_BadInternalCall(): replace PyErr_Format() with _PyErr_SetString(). * Add pycore_pyerrors.h header file. * New functions: * _PyErr_Clear() * _PyErr_Fetch() * _PyErr_Print() * _PyErr_Restore() * _PyErr_SetObject() * _PyErr_SetString() * Add 'tstate' parameter to _PyEval_AddPendingCall().
* bpo-36842: Implement PEP 578 (GH-12613)Steve Dower2019-05-231-0/+6

* bpo-36763: _Py_RunMain() doesn't call Py_Exit() anymore (GH-13390)Victor Stinner2019-05-171-16/+36
| | | | | | | | | Py_Main() and _Py_RunMain() now return the exitcode rather than calling Py_Exit(exitcode) when calling PyErr_Print() if the current exception type is SystemExit. * Add _Py_HandleSystemExit(). * Add pymain_exit_err_print(). * Add pymain_exit_print().
* bpo-36763: Add _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-161-0/+9
| | | | | | | | | * Add a private _Py_InitializeMain() function. * Add again _PyCoreConfig._init_main. * _Py_InitializeFromConfig() now uses _init_main to decide if _Py_InitializeMainInterpreter() should be called. * _PyCoreConfig: rename _frozen to pathconfig_warnings, its value is now the opposite of Py_FrozenFlag. * Add an unit test for _init_main=0 and _Py_InitializeMain().
