* bpo-32726: macOS installer and framework enhancements and changes for 3.7.0 ↵Ned Deily2018-01-307-175/+130
| | | | | | | | | | | | | | (GH-5448) This issue covers various changes for the macOS installers provided via python.org for 3.7.0. - Provide a provisional new installer variant for macOS 10.9 and later systems with 64-bit (x86_64) architecture only. Apple has made it known that future versions of macOS will only fully support 64-bit executables and some other third-party software suppliers have chosen 10.9 as their oldest supported system. - Support **Tcl/Tk 8.6** with the 10.9 installer variant. - Upgrade **OpenSSL** to 1.1.0g and **SQLite** to 3.22.0. - The compiler name used for the interpreter build and for modules built with **Distutils / pip** is now _gcc_ rather than _gcc-4.2_. And extension module builds will no longer try to force use of an old SDK if present.
* bpo-28914: Fix compilation of select on Android (#5447)Victor Stinner2018-01-301-0/+3

* bpo-28440: Don't add /Library/Python/3.x/site-packages to sys.path (#5445)Ned Deily2018-01-303-19/+4
| | | | | | | | No longer add /Library/Python/3.x/site-packages, the Apple-supplied system Python site-packages directory, to sys.path for macOS framework builds in case Apple ships a version of Python 3. A similar change was made earlier to Python 2.7 where it was found that the coupling between the system Python and a user-installed framework Python often caused confusion or pip install failures.
* bpo-32724: Fix references to commands in Doc/pdb.rst (GH-5444)Stéphane Wirtel2018-01-302-5/+10
| | | | | Some commands are specified in the documentation, but there is no direct references.
* bpo-22908: Add seek and tell functionality to ZipExtFile (GH-4966)John Jolly2018-01-304-3/+121

* closes bpo-30117: fix lib2to3 ParserIdempotency test (GH-1242)Eric Appelt2018-01-302-10/+15
| | | | | | | | | | | Fix two (in my opinion) spurious failure conditions in the lib2to3.tests.test_parser.TestParserIdempotency test_parser test. Use the same encoding found in the initial file to write a temp file for a diff. This retains the BOM if the encoding was initially utf-8-sig. If the file cannot be parsed using the normal grammar, try again with no print statement which should succeed for valid files using future print_function For case (1), the driver was correctly handling a BOM in a utf-8 file, but then the test was not writing a comparison file using 'utf-8-sig' to diff against, so the BOM got removed. I don't think that is the fault of the parser, and lib2to3 will retain the BOM. For case (2), lib2to3 pre-detects the use of from __future__ import print_function or allows the user to force this interpretation with a -p flag, and then selects a different grammar with the print statement removed. That makes the test cases unfair to this test as the driver itself doesn't know which grammar to use. As a minimal fix, the test will try using a grammar with the print statement, and if that fails fall back on a grammar without it. A more thorough handling of the idempotency test would to be to parse all files using both grammars and ignore if one of the two failed but otherwise check both. I didn't think this was necessary but can change.
* bpo-32102 Add "capture_output=True" to subprocess.run (GH-5149)Bo Bayles2018-01-305-9/+54
| | | | Add "capture_output=True" option to subprocess.run, this is equivalent to setting stdout=PIPE, stderr=PIPE but is much more readable.

* bpo-21417: Add compresslevel= to the zipfile module (GH-5385)Bo Bayles2018-01-304-24/+104
| | | | | | This allows the compression level to be specified when writing zipfiles (for the entire file *and* overridden on a per-file basis). Contributed by Bo Bayles
* bpo-25942: make subprocess more graceful on ^C (GH-5026)Gregory P. Smith2018-01-303-13/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not allow receiving a SIGINT to cause the subprocess module to trigger an immediate SIGKILL of the child process. SIGINT is normally sent to all child processes by the OS at the same time already as was the established normal behavior in 2.7 and 3.2. This behavior change was introduced during the fix to https://bugs.python.org/issue12494 and is generally surprising to command line tool users who expect other tools launched in child processes to get their own SIGINT and do their own cleanup. In Python 3.3-3.6 subprocess.call and subprocess.run would immediately SIGKILL the child process upon receiving a SIGINT (which raises a KeyboardInterrupt). We now give the child a small amount of time to exit gracefully before resorting to a SIGKILL. This is also the case for subprocess.Popen.__exit__ which would previously block indefinitely waiting for the child to die. This was hidden from many users by virtue of subprocess.call and subprocess.run sending the signal immediately. Behavior change: subprocess.Popen.__exit__ will not block indefinitely when the exiting exception is a KeyboardInterrupt. This is done for user friendliness as people expect their ^C to actually happen. This could cause occasional orphaned Popen objects when not using `call` or `run` with a child process that hasn't exited. Refactoring involved: The Popen.wait method deals with the KeyboardInterrupt second chance, existing platform specific internals have been renamed to _wait(). Also fixes comment typos.

* bpo-28134: Auto-detect socket values from file descriptor (#1349)Christian Heimes2018-01-296-9/+133
| | | | | | | | | | | | | | | Fix socket(fileno=fd) by auto-detecting the socket's family, type, and proto from the file descriptor. The auto-detection can be overruled by passing in family, type, and proto explicitly. Without the fix, all socket except for TCP/IP over IPv4 are basically broken: >>> s = socket.create_connection(('www.python.org', 443)) >>> s <socket.socket fd=3, family=AddressFamily.AF_INET6, type=SocketKind.SOCK_STREAM, proto=6, laddr=('2003:58:bc4a:3b00:56ee:75ff:fe47:ca7b', 59730, 0, 0), raddr=('2a04:4e42:1b::223', 443, 0, 0)> >>> socket.socket(fileno=s.fileno()) <socket.socket fd=3, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('2003:58:bc4a:3b00::%2550471192', 59730, 0, 2550471192), raddr=('2a04:4e42:1b:0:700c:e70b:ff7f:0%2550471192', 443, 0, 2550471192)> Signed-off-by: Christian Heimes <christian@python.org>

* rename _imp initialization function to follow conventions (#5432)Benjamin Peterson2018-01-295-8/+7
| | | When the C imp module became _imp in 6f44d66bc491bad5b8d897a68da68e009e27829d, the initialization function should have been renamed from PyInit_imp to PyInit__imp.

| | | | | (GH-5410) The commit removes one unnecessary "if" clause in genobject.c. That "if" clause was masking un-awaited coroutines warnings just to make writing unittests more convenient.
