* bpo-40334: Produce better error messages on invalid targets (GH-20106)Lysandros Nikolaou2020-06-181-1/+1
| | | | | | | | | | | | | | The following error messages get produced: - `cannot delete ...` for invalid `del` targets - `... is an illegal 'for' target` for invalid targets in for statements - `... is an illegal 'with' target` for invalid targets in with statements Additionally, a few `cut`s were added in various places before the invocation of the `invalid_*` rule, in order to speed things up.

* bpo-40939: Remove the old parser (GH-20768)Pablo Galindo2020-06-111-3/+3
| | | 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-40334: Always show the caret on SyntaxErrors (GH-20050)Lysandros Nikolaou2020-05-131-9/+6
| | | | | | | | | | | | | | This commit fixes SyntaxError locations when the caret is not displayed, by doing the following: - `col_number` always gets set to the location of the offending node/expr. When no caret is to be displayed, this gets achieved by setting the object holding the error line to None. - Introduce a new function `_PyPegen_raise_error_known_location`, which can be called, when an arbitrary `lineno`/`col_offset` needs to be passed. This function then gets used in the grammar (through some new macros and inline functions) so that SyntaxError locations of the new parser match that of the old.
* bpo-40334: Error message for invalid default args in function call (GH-19973)Lysandros Nikolaou2020-05-071-2/+2
| | | | | When parsing something like `f(g()=2)`, where the name of a default arg is not a NAME, but an arbitrary expression, a specialised error message is emitted.
* bpo-40334: Spacialized error message for invalid args after bare '*' (GH-19865)Lysandros Nikolaou2020-05-041-1/+1
| | | When parsing things like `def f(*): pass` the old parser used to output `SyntaxError: named arguments must follow bare *`, which the new parser wasn't able to do.

* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-1/+1
| | | | | | | | | | | * 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-39947: Move get_recursion_depth() to _testinternalcapi (GH-18974)Victor Stinner2020-03-131-1/+1
| | | | | Move get_recursion_depth() function from _testcapi to _testinternalcapi to avoid accessing PyThreadState attributes directly in _testcapi.
* bpo-39882: Py_FatalError() logs the function name (GH-18819)Victor Stinner2020-03-061-2/+3
| | | | | | | | | | | | The Py_FatalError() function is replaced with a macro which logs automatically the name of the current function, unless the Py_LIMITED_API macro is defined. Changes: * Add _Py_FatalErrorFunc() function. * Remove the function name from the message of Py_FatalError() calls which included the function name. * Update tests.
* bpo-39219: Fix SyntaxError attributes in the tokenizer. (GH-17828)Serhiy Storchaka2020-02-121-1/+13

* bpo-36829: Add test.support.catch_unraisable_exception() (GH-13490)Victor Stinner2019-05-221-22/+8
| | | | | | * Copy test_exceptions.test_unraisable() to test_sys.UnraisableHookTest(). * Use catch_unraisable_exception() in test_coroutines, test_exceptions, test_generators.
* bpo-31241: Fix AST node position for list and generator comprehensions. ↵Serhiy Storchaka2018-11-271-1/+1
| | | | | | | | (GH-10633) The lineno and col_offset attributes of AST nodes for list comprehensions, generator expressions and tuples are now point to the opening parenthesis or square brace. For tuples without parenthesis they point to the position of the first item.
* bpo-34683: Make SyntaxError column offsets consistently 1-indexed (gh-9338)Ammar Askar2018-09-241-0/+39

* Issue #29507: Update test_exceptionsVictor Stinner2017-02-091-9/+2
| | | | | | | | | | | | | | | | test_unraisable() of test_exceptions expects that PyErr_WriteUnraisable(method) fails on repr(method). Before the previous change (7b8df4a5d81d), slot_tp_finalize() called PyErr_WriteUnraisable() with a PyMethodObject. In this case, repr(method) calls repr(self) which is BrokenRepr.__repr__() and the calls raises a new exception. After the previous change, slot_tp_finalize() uses an unbound method: repr() is called on a regular __del__() method which doesn't call repr(self). repr() doesn't fail anymore. PyErr_WriteUnraisable() doesn't call __repr__() anymore, so remove BrokenRepr unit test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This restores details lost in revision 097f4fda61a4 (since Python 3.3, related to the new OSError subclasses). Further additions: * Markup for attributes and constructor signature * Explain "winerror" and "filename2" * Extend test to check for filename2 defaulting to None * Clarify that the constructor can return a subclass I have intentionally left out any details of allowing more than five arguments, or how the "args" attribute is set for four or more arguments. These details seem to be dependent on the Python version and platform.
