994d795c4c Fixed bug that caused a crash in the type checker in cases where type arguments were not provided to a few special-case built-in classes. 2020-09-05 18:14:03 -07:00
Eric Traut
cea376e59b Added new diagnostic rule "reportPropertyTypeMismatch" that verifies that the type of the input parameter to a property's setter is assignable to the return type of the getter. 2020-09-05 14:55:12 -07:00

01637af00c Attempt to fix CI, which is hitting errors that I'm not seeing locally. 2020-09-04 21:22:42 -07:00

5979e3423d Extended bidirectional type inference (expected types) to list comprehensions. 2020-09-04 21:12:19 -07:00
Eric Traut
a8406a7b02 Added localized strings for internal errors, which are reported as diagnostics. 2020-09-04 20:57:39 -07:00

35ea405524 Fixed regression in recent check-in that caused an unexpected exception in import resolution code. 2020-09-04 20:57:07 -07:00
Eric Traut
2af28d9379 Changed import resolution logic to allow binaries (e.g. ".so" files) to satisfy local imports (within the package), not just third-party imports (within site-packages). 2020-09-04 20:05:51 -07:00

3f63272dab Improved parser to detect syntax errors involving unpack operator within a comprehension. 2020-09-04 19:54:00 -07:00

1eba08bbe5 Fixed "NoReturn" inference logic for async functions. This logic was previously flagging the code after a call to such a function as unreachable. 2020-09-04 18:50:49 -07:00
Eric Traut
09d6ea7ee0 Changed type inference logic to use "List", "Set", and "Dict" rather than "list", "set" and "dict" when inferring the type of a list, set or dict expression. These are aliases for the same underlying class, but the upper-case versions are more consistent with type annotations used within the code. 2020-09-04 15:38:06 -07:00
Eric Traut
9498da0a69 Fixed a couple of bugs that resulted in the hover text incorrectly identifying a symbol as a "type alias". 2020-09-04 15:36:23 -07:00

Added support for py.typed files to distinguish between packages that… (#1007) 
* Added support for py.typed files to distinguish between packages that claim to have inlined types versus those that don't. Also added support for "partial" stub packages (a "-stub" package that has a py.typed file that includes the line "partial\n" as described in PEP 561).

* Fixed style issue.

* Removed unnecessary truthy tests for results returned by resolveAbsoluteImport.

6c1a285e87 Small cleanup in importResolver. Reordered methods so they are grouped and ordered by public, protected and private. Renamed "_addResultsToCache" to "addResultsToCache" since it is protected. 2020-09-04 11:23:11 -07:00
Eric Traut
60eb2ccad6 Fixed bug that caused the recently-added "discriminated field type narrowing" to be used in cases where it should not. This resulted in types being narrowed inappropriately when a field was typed as a union of literals. 2020-09-03 09:14:23 -07:00

e71ad7d23a Added back the missing "__rootDirectory" global so the CLI can find the typeshed directory. 2020-09-02 18:15:47 -07:00

240794dc43 Fixed crash in CLI due to change in the interface of the "chalk" dependency. 2020-09-02 18:06:54 -07:00

f8124d9554 Fixed broken build script in CLI package.json file. 2020-09-02 18:06:18 -07:00

930c2021c6 Added a check and a general type diagnostic for metaclass conflicts. 2020-09-02 17:35:29 -07:00
Eric Traut
17f0b9e94d Fixed a bug in the Pyright parser. It was not correctly following the Python grammar spec when parsing type annotations, so it generated syntax errors in some cases where that was inappropriate. 2020-09-02 09:16:01 -07:00
Eric Traut
ee4f833005 Fixed default value of reportMissingModuleSource setting in JSON schema. It should be "warning", not "none". 2020-09-02 01:08:40 -07:00

7fd612ad70 Fixed bug in tokenizer that cause line numbers to be off when an invalid token occurred at the end of a line. 2020-09-02 00:28:36 -07:00
Eric Traut
58a349b50e Added check for raise statements that take an exception class but the class constructor requires one or more arguments. 2020-09-01 21:26:10 -07:00
Eric Traut
e168e338dd Fixed an incorrect diagnostic rule for reportMissingTypeArgument. 2020-09-01 20:52:37 -07:00
Eric Traut
e190d4ddef Fixed handling of scopes for nested classes. The previous logic allowed an inner class to access variables defined in an outer class, which is not permitted. 2020-09-01 20:35:08 -07:00
Eric Traut
9e46548fc5 Added new "reportMissingTypeArgument" diagnostic rule and enabled it by default in "strict" mode. It generates a diagnostic when a generic class or generic type alias is used in an annotation with no type arguments provided. Also fixed a bunch of inaccurate settings defaults in pyright's package.json. 2020-09-01 15:59:31 -07:00

f3bbfc3d9a Changed the behavior of the import resolution logic to fail an import resolution of a multi-part name (e.g. "a.b.c") if it can't be fully resolved. This could produce false positives in cases where third-party libraries are using dynamic tricks to manipulate their package namespace, but it will eliminate false negatives. 2020-08-30 11:48:50 -07:00
Eric Traut
e43b5a5c55 Changed heuristics for function return type inference so methods that raise a NotImplementedError and have no other return path have an inferred return type of Unknown rather than NoReturn. Such methods should be marked as abstract, but frequently they are not. 2020-08-30 08:13:41 -07:00

aa63c1d14f Improved completion provider to distinguish properties from other methods. 2020-08-29 21:23:14 -07:00
Eric Traut
520d685d97 Changed handling of dataclass classes that derive from a class whose type is unknown. The synthesized constructor now allows any parameter list in this case. 2020-08-29 16:21:31 -07:00
Eric Traut
e454a96b3e Changed the handling of old-style comment method annotations to accept an optional annotation for "self" and "cls" parameters. 2020-08-29 15:33:40 -07:00
Eric Traut
81d74de105 Eliminated incorrect error when "super()" was used in a class where one or more parent classes were of an unknown type. 2020-08-29 15:18:21 -07:00

f7e5a9975c Updated typeshed fallback stubs to the latest. 2020-08-29 14:51:55 -07:00

Eric Traut
8c5415fd85 Changed diagnostic related to type argument count to be controlled by the "reportGeneralTypeIssues" diagnostic rule. It was previously always emitted as an error. 2020-08-27 09:25:16 -07:00
Eric Traut
950ba3e8a3 Improved completion suggestion behavior when the insertion point is between an identifier and an empty index (e.g. "f[]") or in the presence of a missing right square bracket (e.g. "f.["). 2020-08-26 15:31:35 -07:00
