* closes bpo-32721: do not fail test_hashlib if _md5 isn't available (GH-5441)Benjamin Peterson2018-01-301-1/+1

* bpo-21417: Add compresslevel= to the zipfile module (GH-5385)Bo Bayles2018-01-302-12/+71
| | | | | | 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. Smith2018-01-302-13/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-32604: Expose the subinterpreters C-API in a "private" stdlib module. ↵Eric Snow2018-01-301-0/+1118
| | | | | (gh-1748) The module is primarily intended for internal use in the test suite. Building the module under Windows will come in a follow-up PR.

* bpo-28134: Auto-detect socket values from file descriptor (#1349)Christian Heimes2018-01-293-3/+53
| | | | | | | | | | | | | | | 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>

* bpo-32703: Fix coroutine resource warning in case where there's an error ↵Yury Selivanov2018-01-291-33/+63
| | | | | (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.
* bpo-27931: Fix email address header parsing error (#5329)jayyyin2018-01-292-1/+24

| | | | | | | Add test cases for IDNA 2003 and 2008 host names. IDNA 2003 internationalized host names are working since bpo-31399 has landed. IDNA 2008 deviations are still broken and will be fixed in another patch. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-31429: Define TLS cipher suite on build time (#3532)Christian Heimes2018-01-292-47/+17
| | | | | | | | | | | | | Until now Python used a hard coded white list of default TLS cipher suites. The old approach has multiple downsides. OpenSSL's default selection was completely overruled. Python did neither benefit from new cipher suites (ChaCha20, TLS 1.3 suites) nor blacklisted cipher suites. For example we used to re-enable 3DES. Python now defaults to OpenSSL DEFAULT cipher suite selection and black lists all unwanted ciphers. Downstream vendors can override the default cipher list with --with-ssl-default-suites.

* bpo-32706: Skip test_ftplib.test_check_hostname() (#5422)Victor Stinner2018-01-291-0/+1
| | | | | | This test is unstable and currently prevents to make any new change since the test always fails on Travis CI. Skip the test to get more time to fix it.

| | | | | | | To mitigate the situation when the buildbot is under load and is unable to send/receive data fast enough: * reduce the size of the payload * set a generous timeout for socket ops

* bpo-30306: release arguments of contextmanager (GH-1500)Martin Teichmann2018-01-282-0/+50
| | | | | | | | | | | | | | | | The arguments to a generator function which is declared as a contextmanager are stored inside the context manager, and thus are kept alive, even when it is used as a regular context manager, and not as a function decorator (where it needs the original arguments to recreate the generator on each call). This is a possible unnecessary memory leak, so this changes contextmanager.__enter__ to release the saved arguments, as that method being called means that particular CM instance isn't going to need to recreate the underlying generator. Patch by Martin Teichmann.

| | | Class authors no longer need to specify repr=False if they want to provide a custom __repr__ for dataclasses. The same thing applies for the other dunder methods that the dataclass decorator adds. If dataclass finds that a dunder methods is defined in the class, it will not overwrite it.
