* bpo-32517: fix test_read_pty_output() hangs on macOS 10.13.2+ (GH-6037)Nathan Henrie2018-03-092-0/+3
| | | | | test_asyncio hangs indefinitely on macOS 10.13.2+ on `read_pty_output()` using the KqueueSelector. Closing `proto.transport` (as is done in `write_pty_output()`) seems to fix it.

* bpo-32984: IDLE - set __file__ for startup files (GH-5981)Miss Islington (bot)2018-03-051-0/+7
| | | | | | | | | | | | Like Python, IDLE optionally runs one startup file in the Shell window before presenting the first interactive input prompt. For IDLE, option -s runs a file named in environmental variable IDLESTARTUP or PYTHONSTARTUP; -r file runs file. Python sets __file__ to the startup file name before running the file and unsets it before the first prompt. IDLE now does the same when run normally, without the -n option.

* [3.6] bpo-32981: Fix catastrophic backtracking vulns (GH-5955)Benjamin Peterson2018-03-042-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Prevent low-grade poplib REDOS (CVE-2018-1060) The regex to test a mail server's timestamp is susceptible to catastrophic backtracking on long evil responses from the server. Happily, the maximum length of malicious inputs is 2K thanks to a limit introduced in the fix for CVE-2013-1752. A 2KB evil response from the mail server would result in small slowdowns (milliseconds vs. microseconds) accumulated over many apop calls. This is a potential DOS vector via accumulated slowdowns. Replace it with a similar non-vulnerable regex. The new regex is RFC compliant. The old regex was non-compliant in edge cases. * Prevent difflib REDOS (CVE-2018-1061) The default regex for IS_LINE_JUNK is susceptible to catastrophic backtracking. This is a potential DOS vector. Replace it with an equivalent non-vulnerable regex. Also introduce unit and REDOS tests for difflib.

* bpo-18533: Avoid RecursionError from repr() of recursive dictview (GH-4823)Miss Islington (bot)2018-02-261-0/+3
| | | | | | | | | | | | | | | | | | dictview_repr(): Use a Py_ReprEnter() / Py_ReprLeave() pair to check for recursion, and produce "..." if so. test_recursive_repr(): Check for the string rather than a RecursionError. (Test cannot be any tighter as contents are implementation-dependent.) test_deeply_nested_repr(): Add new test, replacing the original test_recursive_repr(). It checks that a RecursionError is raised in the case of a non-recursive but deeply nested structure. (Very similar to what test_repr_deep() in test/test_dict.py does for a normal dict.) OrderedDictTests: Add new test case, to test behavior on OrderedDict instances containing their own values() or items(). (cherry picked from commit d7773d92bd11640a8c950d6c36a9cef1cee36f96)
