* [3.8] bpo-37482: Fix email address name with encoded words and special chars ↵bsiem2019-08-292-0/+27
| | | | | | | | | | | | | | | | | | | | | | (GH-14561) (GH-15380) Special characters in email address header display names are normally put within double quotes. However, encoded words (=?charset?x?...?=) are not allowed withing double quotes. When the header contains a word with special characters and another word that must be encoded, the first one must also be encoded. In the next example, the display name in the From header is quoted and therefore the comma is allowed; in the To header, the comma is not within quotes and not encoded, which is not allowed and therefore rejected by some mail servers.

* [3.8] bpo-37757: Disallow PEP 572 cases that expose implementation details ↵Nick Coghlan2019-08-263-38/+84
| | | | | | | | | | | | | | | | | | | (GH-15491) - drop TargetScopeError in favour of raising SyntaxError directly as per the updated PEP 572 - comprehension iteration variables are explicitly local, but named expression targets in comprehensions are nonlocal or global. Raise SyntaxError as specified in PEP 572 - named expression targets in the outermost iterable of a comprehension have an ambiguous target scope. Avoid resolving that question now by raising SyntaxError. PEP 572 originally required this only for cases where the bound name conflicts with the iteration variable in the comprehension, but CPython can't easily restrict the exception to that case (as it doesn't know the target variable names when visiting the outermost iterator expression) (cherry picked from commit 5dbe0f59b7a4f39c7c606b48056bc29e406ebf78)
* bpo-37929: IDLE: avoid Squeezer-related config dialog crashes (GH-15452)Miss Islington (bot)2019-08-243-50/+26
| | | | | | | | | | | | These were caused by keeping around a reference to the Squeezer instance and calling it's load_font() upon config changes, which sometimes happened even if the shell window no longer existed. This change completely removes that mechanism, instead having the editor window properly update its width attribute, which can then be used by Squeezer.

| | | | | | | | | | | | | | | | If this service had thoroughly vanished, we could just ignore the test until someone gets around to either recreating such a service or redesigning the test to somehow work locally. The `support.transient_internet` mechanism catches the failure to resolve the domain name, and skips the test. But in fact the domain snakebite.net does still exist, as do its nameservers -- and they can be quite slow to reply. As a result this test can easily take 20-30s before it gets auto-skipped. So, skip the test explicitly up front. (cherry picked from commit 5b95a1507e349da5adae6d2ab57deac3bdd12f15) Co-authored-by: Greg Price <gnprice@gmail.com>

| | | | | | | | | | | | | | | | | | The documented definition was much broader than the real one: there are tons of characters with general category "Other", and we don't (and shouldn't) treat most of them as whitespace. Rewrite the definition to agree with the comment on _PyUnicode_IsWhitespace, and with the logic in makeunicodedata.py, which is what generates that function and so ultimately governs. Add suitable breadcrumbs so that a reader who wants to pin down exactly what this definition means (what's a "bidirectional class" of "B"?) can do so. The `unicodedata` module documentation is an appropriate central place for our references to Unicode's own copious documentation, so point there. Also add to the isspace() test a thorough check that the implementation agrees with the intended definition.
