* bpo-40162: Update Travis CI config to OpenSSL 1.1.1f (GH-19319)Victor Stinner2020-04-031-0/+1

* lib2to3: Support named assignment expressions (GH-12702)Tim Hatch2020-04-021-0/+2
| | | | | | | | | | | | There are two copies of the grammar -- the one used by Python itself as Grammar/Grammar, and the one used by lib2to3 which has necessarily diverged at Lib/lib2to3/Grammar.txt because it needs to support older syntax an we want it to be reasonable stable to avoid requiring fixer rewrites. This brings suport for syntax like `if x:= foo():` to match what the live Python grammar does. This should've been added at the time of the walrus operator itself, but lib2to3 being independent is often overlooked. So we do consider this a bugfix rather than enhancement.
* bpo-1635741: Port resource extension module to multiphase initialization ↵Hai Shi2020-04-021-0/+1
| | | | | (PEP 489) (GH-19252) Fix also reference leaks on error.
* bpo-40094: Fix which.py script exit code (GH-19286)Victor Stinner2020-04-021-0/+3
| | | | It now uses os.waitstatus_to_exitcode() to convert os.system() exit status into an exit code.
* bpo-40094: CGIHTTPRequestHandler logs exit code (GH-19285)Victor Stinner2020-04-021-0/+3
| | | | | | | CGIHTTPRequestHandler of http.server now logs the CGI script exit code, rather than the CGI script exit status of os.waitpid(). For example, if the script is killed by signal 11, it now logs: "CGI script exit code -11."
* bpo-37207: Use PEP 590 vectorcall to speed up dict() (GH-19280)Dong-hee Na2020-04-021-0/+2

* bpo-39503: CVE-2020-8492: Fix AbstractBasicAuthHandler (GH-18284)Victor Stinner2020-04-022-0/+8
| | | | | | | | | | | | | The AbstractBasicAuthHandler class of the urllib.request module uses an inefficient regular expression which can be exploited by an attacker to cause a denial of service. Fix the regex to prevent the catastrophic backtracking. Vulnerability reported by Ben Caller and Matt Schwager. AbstractBasicAuthHandler of urllib.request now parses all WWW-Authenticate HTTP headers and accepts multiple challenges per header: use the realm of the first Basic challenge.

* bpo-40141: Add line and column information to ast.keyword nodes (GH-19283)Pablo Galindo2020-04-021-0/+2

* bpo-40094: Add os.waitstatus_to_exitcode() (GH-19201)Victor Stinner2020-04-011-0/+2
| | | | | | | | | | | | | | Add os.waitstatus_to_exitcode() function to convert a wait status to an exitcode. Suggest waitstatus_to_exitcode() usage in the documentation when appropriate. Use waitstatus_to_exitcode() in: * multiprocessing, os, subprocess and _bootsubprocess modules; * test.support.wait_process(); * setup.py: run_command(); * and many tests.
* bpo-38527: fix configure script for Solaris (GH-16845)Arnon Yaari2020-04-011-0/+2
| | | | | On Solaris, the regular "grep" command may be an old version that fails to search a binary file. We need to use the correct command (ggrep, in our case), which is found by the configure script earlier. Automerge-Triggered-By: @pablogsal
* bpo-39682: make `pathlib.Path` immutable by removing (undocumented) support ↵Barney Gale2020-04-011-0/+3
| | | | | | for "closing" a path by using it as a context manager (GH-18846) Support for using a path as a context manager remains, and is now a no-op.
* bpo-33262: Deprecate passing None for `s` to shlex.split() (GH-6514)Zackery Spytz2020-04-011-0/+2
| | | | | | | | | * bpo-33262: Deprecate passing None for `s` to shlex.split() This reads the string to split from standard input. * Update What's New. * Fix shlex.rst
* bpo-40094: Add test.support.wait_process() (GH-19254)Victor Stinner2020-03-311-0/+1
| | | | | | | | | Moreover, the following tests now check the child process exit code: * test_os.PtyTests * test_mailbox.test_lock_conflict() * test_tempfile.test_process_awareness() * test_uuid.testIssue8621() * multiprocessing resource tracker tests
* bpo-40003: test.bisect_cmd copies Python options (GH-19246)Victor Stinner2020-03-311-0/+3
| | | | | test.bisect_cmd now copies Python command line options like -O or -W. Moreover, emit a warning if test.bisect_cmd is used with -w/--verbose2 option.

* bpo-40020: Fix realloc leak on failure in growable_comment_array_add (GH-19083)Alexander Riccio2020-03-301-0/+1
| | | | | Fix a leak and subsequent crash in parsetok.c caused by realloc misuse on a rare codepath. Realloc returns a null pointer on failure, and then growable_comment_array_deallocate crashes later when it dereferences it.
* bpo-8901: Windows registry path is now ignored with the -E option (GH-18169)Zackery Spytz2020-03-301-0/+1

* bpo-37207: Use vectorcall for list() (GH-18928)Petr Viktorin2020-03-301-0/+2

* bpo-39073: validate Address parts to disallow CRLF (#19007)Ashwin Ramaswami2020-03-291-0/+1
| | | Disallow CR or LF in email.headerregistry.Address arguments to guard against header injection attacks.
* bpo-39812: Remove daemon threads in concurrent.futures (GH-19149)Kyle Stanley2020-03-271-0/+4
| | | | | | Remove daemon threads from :mod:`concurrent.futures` by adding an internal `threading._register_atexit()`, which calls registered functions prior to joining all non-daemon threads. This allows for compatibility with subinterpreters, which don't support daemon threads.
* bpo-40089: Fix threading._after_fork() (GH-19191)Victor Stinner2020-03-271-0/+3
| | | | | If fork was not called by a thread spawned by threading.Thread, threading._after_fork() now creates a _MainThread instance for _main_thread, instead of a _DummyThread instance.
* bpo-40077: Convert _json module to use PyType_FromSpec() (GH-19177)Dong-hee Na2020-03-271-0/+1
| | | | | | | Replace statically allocated types with heap allocated types: use PyType_FromSpec(). Add a module state to store the Scanner and Encoder types. Add traverse, clear and free functions to the module.
* bpo-1812: Fix newline conversion when doctest.testfile loads from a package ↵Peter Donis2020-03-262-0/+3
| | | | | whose loader has a get_data method (GH-17385) This pull request fixes the newline conversion bug originally reported in bpo-1812. When that issue was originally submitted, the open builtin did not default to universal newline mode; now it does, which makes the issue fix simpler, since the only code path that needs to be changed is the one in doctest._load_testfile where the file is loaded from a package whose loader has a get_data method.

* bpo-40014: Fix os.getgrouplist() (GH-19126)Victor Stinner2020-03-241-3/+4
| | | | | | | | Fix os.getgrouplist(): if getgrouplist() function fails because the group list is too small, retry with a larger group list. On failure, the glibc implementation of getgrouplist() sets ngroups to the total number of groups. For other implementations, double the group list size.
* bpo-40050: Fix importlib._bootstrap_external (GH-19135)Victor Stinner2020-03-241-0/+3
| | | | | | Remove two unused imports: _thread and _weakref. Avoid creating a new winreg builtin module if it's already available in sys.modules. The winreg module is now stored as "winreg" rather than "_winreg".
* bpo-20526: Fix PyThreadState_Clear(): don't decref frame (GH-19120)Victor Stinner2020-03-241-0/+3
| | | | | | | | PyThreadState.frame is a borrowed reference, not a strong reference: PyThreadState_Clear() must not call Py_CLEAR(tstate->frame). Remove test_threading.test_warnings_at_exit(): we cannot warranty that the Python thread state of daemon threads is cleared in a reliable way during Python shutdown.
