* bpo-33175: dataclasses should look up __set_name__ on class, not instance ↵Eric V. Smith2018-03-292-7/+36

* bpo-32517: fix test_read_pty_output() hangs on macOS 10.13.2+ (GH-6037) ↵Ned Deily2018-03-271-1/+1
| | | | | | | | | | | | (GH-6113) 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. (cherry picked from commit 12f74d8608c15cacd9d5786524e2be9ca36f007e) Co-authored-by: Nathan Henrie <n8henrie@users.noreply.github.com> Also, re-enable test_read_pty_output on macOS.

* bpo-32873: Treat type variables and special typing forms as immutable by ↵Ivan Levkivskyi2018-03-262-11/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | copy and pickle (GH-6216) This also fixes python/typing#512 This also fixes python/typing#511 As was discussed in both issues, some typing forms deserve to be treated as immutable by copy and pickle modules, so that: * copy(X) is X * deepcopy(X) is X * loads(dumps(X)) is X # pickled by reference This PR adds such behaviour to: * Type variables * Special forms like Union, Any, ClassVar * Unsubscripted generic aliases to containers like List, Mapping, Iterable This not only resolves inconsistencies mentioned in the issues, but also improves backwards compatibility with previous versions of Python (including 3.6). Note that this requires some dances with __module__ for type variables (similar to NamedTuple) because the class TypeVar itself is define in typing, while type variables should get module where they were defined. https://bugs.python.org/issue32873
* bpo-32844: Fix a subprocess misredirection of a low fd (GH5689)Alexey Izbyshev2018-03-261-0/+50
| | | | | | | | | | bpo-32844: subprocess: Fix a potential misredirection of a low fd to stderr. When redirecting, subprocess attempts to achieve the following state: each fd to be redirected to is less than or equal to the fd it is redirected from, which is necessary because redirection occurs in the ascending order of destination descriptors. It fails to do so in a couple of corner cases, for example, if 1 is redirected to 2 and 0 is closed in the parent.
* bpo-33141: Have dataclasses.Field pass through __set_name__ to any default ↵Eric V. Smith2018-03-262-0/+56
| | | | | argument. (GH-6260) This is part of PEP 487 and the descriptor protocol.
* bpo-6986: Add a comment to clarify a test of _json.make_encoder(). (GH-3789)Oren Milman2018-03-261-0/+2

* bpo-33096: Fix ttk.Treeview.insert. (GH-6228)Garvit Khatri2018-03-262-1/+10
| | | | | Allow ttk.Treeview.insert to insert iid that has a false boolean value. Note iid=0 and iid=False would be same.
* Minor fixes to dataclass tests. (GH-6243)Eric V. Smith2018-03-261-42/+41
| | | Also, re-enable a test for ClassVars with default_factory.
* bpo-33053: Remove test_cmd_line_script debugging print (GH-6237)Nick Coghlan2018-03-251-2/+0
| | | | I noticed this had slipped into the original commit when resolving a merge conflict for the backport to 3.7.
* Trivial improvements to dataclasses tests. (GH-6234)Eric V. Smith2018-03-251-2/+3

* bpo-33053: -m now adds *starting* directory to sys.path (GH-6231)Nick Coghlan2018-03-255-67/+70
| | | | | | | | | | | | Historically, -m added the empty string as sys.path zero, meaning it resolved imports against the current working directory, the same way -c and the interactive prompt do. This changes the sys.path initialisation to add the *starting* working directory as sys.path[0] instead, such that changes to the working directory while the program is running will have no effect on imports when using the -m switch.
* bpo-33042: Fix pre-initialization sys module configuration (GH-6157)Nick Coghlan2018-03-251-5/+26
| | | | | | | | | - new test case for pre-initialization of sys.warnoptions and sys._xoptions - restored ability to call these APIs prior to Py_Initialize - updated the docs for the affected APIs to make it clear they can be called before Py_Initialize - also enhanced the existing embedding test cases to check for expected settings in the sys module
* bpo-33136: Harden ssl module against CVE-2018-8970 (GH-6229)Christian Heimes2018-03-251-0/+3
| | | | | | | Harden ssl module against LibreSSL CVE-2018-8970. X509_VERIFY_PARAM_set1_host() is called with an explicit namelen. A new test ensures that NULL bytes are not allowed. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-33134: dataclasses: use function dispatch table for hash, instead of a ↵Eric V. Smith2018-03-251-40/+36
| | | | | | | string lookup which then is tested with if tests. (GH-6222) * Change _hash_action to be a function table lookup, instead of a list of strings which is then tested with if statements.
* Trivial dataclass cleanups: (GH-6218)Eric V. Smith2018-03-241-23/+26
| | | | | | | | | | - When adding a single element to a list, use .append() instead of += and creating a new list. - For consistency, import the copy module, instead of just deepcopy. This leaves only a module at the class level, instead of a function. - Improve some comments. - Improve some whitespace. - Use tuples instead of lists. - Simplify a test.
* bpo-24334: Remove inaccurate match_hostname call (#6211)Christian Heimes2018-03-241-5/+0
| | | | | | Commit 141c5e8c re-added match_hostname() call. The resurrection of the function call was never intended and was solely a merge mistake. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-33041: Rework compiling an "async for" loop. (#6142)Serhiy Storchaka2018-03-235-4/+89
| | | | | | | | * Added new opcode END_ASYNC_FOR. * Setting global StopAsyncIteration no longer breaks "async for" loops. * Jumping into an "async for" loop is now disabled. * Jumping out of an "async for" loop no longer corrupts the stack. * Simplify the compiler.
* bpo-32505: dataclasses: raise TypeError if a member variable is of type ↵Eric V. Smith2018-03-222-17/+64
| | | | | Field, but doesn't have a type annotation. (GH-6192) If a dataclass has a member variable that's of type Field, but it doesn't have a type annotation, raise TypeError.
* bpo-33018: Improve issubclass() error checking and message. (GH-5944)jab2018-03-221-0/+2
| | | | | This improves error message for situations when a non-class is checked w.r.t. an abstract base class.

* bpo-27683: Fix a regression for host() of ipaddress network objects (GH-6016)Xiang Zhang2018-03-212-74/+61
| | | | | | The result of host() was not empty when the network is constructed by a tuple containing an integer mask and only 1 bit left for addresses.
* bpo-18802: Add more details to ipaddress documentation (GH-6083)Cheryl Sabella2018-03-211-0/+3

* bpo-33100: Dataclasses now handles __slots__ and default values correctly. ↵Eric V. Smith2018-03-202-0/+45
| | | | | (GH-6152) If the class has a member that's a MemberDescriptorType, it's not a default value, it's from that member being in __slots__.

* bpo-32953: Dataclasses: frozen should not be inherited for non-dataclass ↵Eric V. Smith2018-03-192-55/+164
| | | | | | | derived classes (#6147) If a non-dataclass derives from a frozen dataclass, allow attributes to be set. Require either all of the dataclasses in a class hierarchy to be frozen, or all non-frozen. Store `@dataclass` parameters on the class object under `__dataclass_params__`. This is needed to detect frozen base classes.

| | | | | Multi-phase initialized modules allow m_traverse to be called while the module is still being initialized, so module authors may need to account for that.
