* bpo-40939: Rename PyPegen* functions to PyParser* (GH-21016)Lysandros Nikolaou2020-06-228-79/+52
| | | | | | Rename PyPegen* functions to PyParser*, so that we can remove the old set of PyParser* functions that were using the old parser.

* bpo-41060: Avoid SEGFAULT when calling GET_INVALID_TARGET in the grammar ↵Lysandros Nikolaou2020-06-214-26/+38
| | | | | | | | | (GH-21020) `GET_INVALID_TARGET` might unexpectedly return `NULL`, which if not caught will cause a SEGFAULT. Therefore, this commit introduces a new inline function `RAISE_SYNTAX_ERROR_INVALID_TARGET` that always checks for `GET_INVALID_TARGET` returning NULL and can be used in the grammar, replacing the long C ternary operation used till now.
* bpo-41056: Use the fildes converter for fd to please Coverity. (GH-21011)Gregory P. Smith2020-06-203-5/+5
| | | | | | | | | There are a bunch of other fd: int uses in this file, I expect many if not all of them would be better off using the fildes converter. This particular one was flagged by Coverity as it presumably flags fpathconf as not accepting negative fds. I'd expect the other fd's to have been flagged as well otherwise. I'm marking this one as skip news as it really is a no-op.
* bpo-41056: Fix a NULL pointer dereference on MemoryError within the ssl ↵Gregory P. Smith2020-06-202-6/+7

* Add link to .pypirc specification (GH-20680)Brian Rutledge2020-06-201-0/+3
| | | | | Related to https://github.com/pypa/twine/issues/638 and https://github.com/pypa/packaging.python.org/issues/730, I wrote a spec based on the one that was removed in https://github.com/python/cpython/pull/13087. However, a Google search for "pypirc" turned up at least one [blog post](https://truveris.github.io/articles/configuring-pypirc/) that links to https://docs.python.org/3/distutils/packageindex.html#the-pypirc-file, which now just links to this document. So, I thought a link to the spec would be handy. Automerge-Triggered-By: @jaraco

| | | | | | | The PY_SSIZE_T_CLEAN macro must now be defined to use PyArg_ParseTuple() and Py_BuildValue() "#" formats: "es#", "et#", "s#", "u#", "y#", "z#", "U#" and "Z#". See the PEP 353. Update _testcapi.test_buildvalue_issue38913().
* bpo-40334: Produce better error messages on invalid targets (GH-20106)Lysandros Nikolaou2020-06-196-1454/+1849
| | | | | | | | | | | | | | 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.
