* bpo-29587: _PyErr_ChainExceptions() checks exception (GH-19902)Victor Stinner2020-05-054-24/+45
| | | | | | | | | | | | | | | | | | | _PyErr_ChainExceptions() now ensures that the first parameter is an exception type, as done by _PyErr_SetObject(). * The following function now check PyExceptionInstance_Check() in an assertion using a new _PyBaseExceptionObject_cast() helper function: * PyException_GetTraceback(), PyException_SetTraceback() * PyException_GetCause(), PyException_SetCause() * PyException_GetContext(), PyException_SetContext() * PyExceptionClass_Name() now checks PyExceptionClass_Check() with an assertion. * Remove XXX comment and add gi_exc_state variable to _gen_throw(). * Remove comment from test_generators
* bpo-40513: Per-interpreter recursion_limit (GH-19929)Victor Stinner2020-05-054-22/+28
| | | | | | | | | | | Move recursion_limit member from _PyRuntimeState.ceval to PyInterpreterState.ceval. * Py_SetRecursionLimit() now only sets _Py_CheckRecursionLimit of ceval.c if the current Python thread is part of the main interpreter. * Inline _Py_MakeEndRecCheck() into _Py_LeaveRecursiveCall(). * Convert _Py_RecursionLimitLowerWaterMark() macro into a static inline function.

* bpo-40514: Add --with-experimental-isolated-subinterpreters (GH-19926)Victor Stinner2020-05-055-0/+60
| | | | | | | Add --with-experimental-isolated-subinterpreters build option to configure: better isolate subinterpreters, experimental build mode. When used, force the usage of the libc malloc() memory allocator, since pymalloc relies on the unique global interpreter lock (GIL).
* bpo-40513: Per-interpreter gil_drop_request (GH-19927)Victor Stinner2020-05-054-47/+45
| | | | Move gil_drop_request member from _PyRuntimeState.ceval to PyInterpreterState.ceval.

* bpo-40246: Revert reporting of invalid string prefixes (GH-19888)Lysandros Nikolaou2020-05-046-12/+2
| | | | 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: Spacialized error message for invalid args after bare '*' (GH-19865)Lysandros Nikolaou2020-05-045-210/+472
| | | 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.

| | | Due to PyErr_Occurred not being called at the beginning of each rule, we need to set the error indicator, so that rules do not get expanded after an exception has been thrown

* bpo-29587: allow chaining NULL exceptions in _gen_throw() (GH-19877)Chris Jerdonek2020-05-032-4/+25
| | | | | | | | | | | | | This is a follow-up to GH-19823 that removes the check that the exception value isn't NULL, prior to calling _PyErr_ChainExceptions(). This enables implicit exception chaining for gen.throw() in more circumstances. The commit also adds a test that a particular code snippet involving gen.throw() doesn't crash. The test shows why the new `gi_exc_state.exc_type != Py_None` check that was added is necessary. Without the new check, the code snippet (as well as a number of other tests) crashes on certain platforms (e.g. Fedora but not Mac).

* bpo-29587: Update gen.throw() to chain exceptions (#19823)Chris Jerdonek2020-05-013-0/+27
| | | | | | | Before this commit, if an exception was active inside a generator when calling gen.throw(), that exception was lost (i.e. there was no implicit exception chaining). This commit fixes that by setting exc.__context__ when calling gen.throw(exc).
* bpo-40417: Fix deprecation warning in PyImport_ReloadModule (GH-19750)Robert Rouhani2020-05-012-7/+8

* bpo-40412: Nullify inittab_copy during finalization (GH-19746)Gregory Szorc2020-05-012-0/+2
| | | | | | | | | Otherwise we leave a dangling pointer to free'd memory. If we then initialize a new interpreter in the same process and call PyImport_ExtendInittab, we will (likely) crash when calling PyMem_RawRealloc(inittab_copy, ...) since the pointer address is bogus.

* bpo-40334: Make the PyPegen* and PyParser* APIs more consistent (GH-19839)Lysandros Nikolaou2020-05-013-106/+36
| | | | | | | | | This commit makes both APIs more consistent by doing the following: - Remove the `PyPegen_CodeObjectFrom*` functions, which weren't used and will probably not be needed. Functions like `Py_CompileStringObject` can be used instead. - Include a `const char *filename` parameter in `PyPegen_ASTFromString`. - Rename `PyPegen_ASTFromFile` to `PyPegen_ASTFromFilename`, because its signature is not the same with `PyParser_ASTFromFile`.
