* bpo-38488: Upgrade bundled versions of pip & setuptools (GH-20491) (GH-20900)Ned Deily2020-06-156-7/+8

* 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.

* bpo-34226: fix cgi.parse_multipart without content_length (GH-8530)Miss Islington (bot)2020-06-153-2/+21
| | | | | | | | | | | | In Python 3.7 the behavior of parse_multipart changed requiring CONTENT-LENGTH header, this fix remove this header as required and fix FieldStorage read_lines_to_outerboundary, by not using limit when it's negative, since by default it's -1 if not content-length and keeps substracting what was read from the file object. Also added a test case for this problem. (cherry picked from commit d8cf3514dd4682419a66f6e834bb384ee34afc95) Co-authored-by: roger <rogerduran@gmail.com>

* [3.8] bpo-40895: Update weakref documentation to remove old warnings ↵Antoine Pitrou2020-06-101-14/+0
| | | | | | | | | | | | | | | | | (GH-20687) (GH-20792) 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.

It is fairly common to find malformed mime headers (especially content-disposition headers) where the parameter values, instead of being encoded to RFC standards, are "encoded" by doing RFC 2047 "encoded word" encoding, and then enclosing the whole thing in quotes. The processing of these malformed headers was incorrectly leaving the spaces between encoded words in the decoded text (whitespace between adjacent encoded words is supposed to be stripped on decoding). This changeset fixes the encoded word processing inside quoted strings (bare-quoted-string) to do correct RFC 2047 decoding by stripping that whitespace.
