* bpo-46442: improve and rename testExceptionCleanupNames (GH-30758)Miss Islington (bot)2022-01-221-2/+14
| | | | | | | | The test tested that explicitly deleting the local variable bound to the exception did not cause problems, but it did not test what it actually claimed to test, i.e. that the variable is deleted automatically.

* [3.9] bpo-45494: Fix parser crash when reporting errors involving invalid ↵Łukasz Langa2021-10-201-0/+4
| | | | | | | | | | | | | | | | | | | continuation characters (GH-28993) (#29071) There are two errors that this commit fixes: * The parser was not correctly computing the offset and the string source for E_LINECONT errors due to the incorrect usage of strtok(). * The parser was not correctly unwinding the call stack when a tokenizer exception happened in rules involving optionals ('?', [...]) as we always make them return valid results by using the comma operator. We need to check first if we don't have an error before continuing.. (cherry picked from commit a106343f632a99c8ebb0136fa140cf189b4a6a57) Co-authored-by: Pablo Galindo Salgado <Pablogsal@gmail.com> NOTE: unlike the cherry-picked original, this commit points at a crazy location due to a bug in the tokenizer that required a big refactor in 3.10 to fix. We are leaving as-is for 3.9.

| | | | | | | (#25179) This reverts commit 8b795ab5541d8a4e69be4137dfdc207714270b77. It changed the PyThreadState structure size, breaking the ABI in 3.9.3.

* [3.9] bpo-41654: Fix deallocator of MemoryError to account for subclasses ↵Pablo Galindo2020-09-011-0/+31
| | | | | | | | | | | | (GH-22020) (GH-22045) When allocating MemoryError classes, there is some logic to use pre-allocated instances in a freelist only if the type that is being allocated is not a subclass of MemoryError. Unfortunately in the destructor this logic is not present so the freelist is altered even with subclasses of MemoryError..

* [3.9] bpo-40334: Produce better error messages on invalid targets (GH-20106) ↵Lysandros Nikolaou2020-06-191-1/+1
| | | | | | | | | | | | | | | | | | | (GH-20973) * bpo-40334: Produce better error messages on invalid targets (GH-20106) 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-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.

| | | | | | | | | | | * 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-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.

* 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.

These details seem to be dependent on the Python version and platform.
