Eric Traut	c544a75fbb	Changed method and attribute override compatibility checks to check for inappropriate overrides of all base classes in the multi-inheritance case. Previously, this check used MRO, so some override mismatches were left unreported if they were obscured by another base class. The change also affects @final checks.	2021-08-08 18:28:47 -07:00
Eric Traut	1b54ffc291	Fixed a bug that was masking some error messages when multiple errors were reported for the same range and their message started with the same 25 characters.	2021-08-08 18:20:12 -07:00
Eric Traut	315da0227e	Added heuristic to allow proper inference of list expressions when used as the RHS operand in an expression of the form my_list + [x].	2021-08-08 13:17:12 -07:00
Eric Traut	67dc7f7385	Improved logging for import failures. The previous code was printing the same log message for both stub and non-stub package resolution attempts which resulted in seemingly redundant messages.	2021-08-08 09:13:24 -07:00
Eric Traut	0bf45ea2ed	Added support for new type narrowing pattern for discriminating among tuples. The pattern is V[I] == L or V[I] != L where I is an integer literal, L is another literal value, V is a tuple with a known length and a type at index I that is declared as a literal type.	2021-08-06 23:17:21 -07:00
Eric Traut	2acdd174f0	Added support for bidirectional type inference for assignment expressions where the LHS is an index expression that indexes into a TypedDict instance.	2021-08-06 08:36:32 -07:00
Eric Traut	923eb705c3	Fixed bug that resulted in a false when evaluating nested lambdas (i.e. a lambda that returns a lambda).	2021-08-06 08:14:16 -07:00
Eric Traut	0cf1c82563	Fixed bug in declaration provider that caused declaration not to be found when it referred to a metadata method.	2021-08-06 08:13:37 -07:00
Eric Traut	7dbd463f4a	Published 1.1.160	2021-08-05 23:17:24 -07:00
Eric Traut	015de94f89	Implemented support for new Python 3.10 dataclass features: kw_only parameter for dataclass and field and KW_ONLY separator.	2021-08-05 23:10:58 -07:00
Eric Traut	74a24b7efc	Fixed bug in the handling of generic recursive type aliases.	2021-08-05 20:33:37 -07:00
Eric Traut	111d3b8a98	Removed the assumption that all top-level modules in typeshed third-party stubs are unique. The typeshed folder structure allows multiple packages to have the same top-level module.	2021-08-05 16:53:25 -07:00
Jake Bailey	9ba8d6bdba	Update dependencies (#2156)	2021-08-05 16:03:07 -07:00

Eric Traut	94ba4e21e3	Fixed bug where a union of Literal[False] and Literal[True] were being coalesced into bool inappropriately in the case where they were conditional types that came from a constrained TypeVar.	2021-08-05 13:47:51 -07:00
Eric Traut	8ee2fc001e	Fixed bug that verified that a protocol class used within an isinstance call is runtime_checkable. It was skipping this check when the first argument to isinstance was an Any or Unknown type.	2021-08-05 13:47:51 -07:00
Heejae Chang	dfb796d84c	upgrade vscode dependency to 1.57 (#2147)	2021-08-04 12:26:18 -07:00

Eric Traut	7ee5feb4e7	Fixed false positive that occurs when defining an abstract dataclass and one of its fields refers to the class itself in its type annotation.	2021-08-03 07:01:42 -07:00
Eric Traut	bfc4fc3a13	Updated typeshed stubs to the latest version	2021-08-01 08:30:52 -07:00
Eric Traut	1d015d2db3	Fixed bug that prevented "rename symbol" from working when in single-file mode. Rather than failing, it will now perform a rename only within a single file.	2021-08-01 08:13:08 -07:00
Eric Traut	a7df474075	Updated the "type(x) is y" type narrowing logic to handle the negative case when the class type is "final".	2021-07-31 19:29:28 -07:00

Eric Traut	f5676d3c0c	Modified assignment type narrowing for index expressions so it applies only to built-in types. This eliminates incorrect type inference when using a class that has assymetric __setitem__ and __getitem__ methods.	2021-07-29 21:02:32 -07:00
Eric Traut	ab49b4254d	Added logic to enforce protocol mismatches if a member in the protocol is marked "Final" and the class is not (or vice versa).	2021-07-29 20:36:08 -07:00
Eric Traut	4d727e7290	Added check for inappropriate use of ClassVar that will generate runtime exceptions.	2021-07-29 14:50:07 -07:00
Eric Traut	6a867b651a	Implemented new check for a class that is decorated with @final but does not implement all abstract methods from abstract classes that it derives from.	2021-07-29 14:11:55 -07:00

Eric Traut	8f79bc2cab	Added check for illegal trailing comma in "from x import y," statement. This generates a syntax error at runtime.	2021-07-29 00:23:03 -07:00
