* [3.9] bpo-41060: Avoid SEGFAULT when calling GET_INVALID_TARGET in the ↵Lysandros Nikolaou2020-06-214-26/+38
| | | | | | | | | | | | | grammar (GH-21020) (GH-21024) `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.

| | | | | | | | 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.htmlGH-the-pypirc-file, which now just links to this document. So, I thought a link to the spec would be handy.

* bpo-40448: ensurepip: Do not use cache (GH-19812)Miss Islington (bot)2020-06-154-9/+12
| | | | | | | | | | | | | | | | | ensurepip optionally installs or upgrades 'pip' and 'setuptools' using the version of those modules bundled with Python. The internal PIP installation routine by default temporarily uses its cache, if it exists. This is undesirable as Python builds and installations may be independent of the user running the build, whilst PIP cache location is dependent on the user's environment and outside of the build environment. At the same time, there's no value in using the cache while installing bundled modules. This change disables PIP caching when used in ensurepip.

| | | | | | | | | | | | | The doccumentation at https://docs.python.org/3.10/library/weakref.html cautions that the `WeakKeyDictionary` and `WeakValueDictionary` are susceptible to the problem of dictionary mutation during iteration. These notes present the user with a problem that has no easy solution. I dug into the implementation and found that fortunately, Antoine Pitrou already addressed this challenge (10 years ago!) by introducing an `_IterationGuard` context manager to the implementation, which delays mutation while an iteration is in progress. I asked for confirmation and @pitrou agreed that these notes could be removed: https://github.com/python/cpython/commit/c1baa601e2b558deb690edfdf334fceee3b03327GH-commitcomment-39514438 (cherry picked from commit 1642c0ef750f96664a98cadb09301d492098d2fb) Co-authored-by: Daniel Fortunov <asqui@users.noreply.github.com>
