Matej Cepl <mcepl@cepl.eu> - Clean up SPEC file. ------------------------------------------------------------------- Mon Mar 18 14:33:02 UTC 2024 - Dan Čermák <dcermak@suse.com> New upstream release 1.9.0 #### Breaking Changes Because the version of typeshed we use in mypy 1.9 doesn't support 3.7, neither does mypy 1.9. (Jared Hance, PR [16883](https://github.com/python/mypy/pull/16883)) We are planning to enable [local partial types](https://mypy.readthedocs.io/en/stable/command_line.html#cmdoption-mypy-local-partial-types) (enabled via the `--local-partial-types` flag) later this year by default. This change was announced years ago, but now it's finally happening. This is a major backward-incompatible change, so we'll probably include it as part of the upcoming mypy 2.0 release. This makes daemon and non-daemon mypy runs have the same behavior by default. Local partial types can also be enabled in the mypy config file: ``` local_partial_types = True ``` We are looking at providing a tool to make it easier to migrate projects to use `--local-partial-types`, but it's not yet clear whether this is practical. The migration usually involves adding some explicit type annotations to module-level and class-level variables. #### Basic Support for Type Parameter Defaults (PEP 696) This release contains new experimental support for type parameter defaults ([PEP 696](https://peps.python.org/pep-0696)). Please try it out! This feature was contributed by Marc Mueller. Since this feature will be officially introduced in the next Python feature release (3.13), you will need to import `TypeVar`, `ParamSpec` or `TypeVarTuple` from `typing_extensions` to use defaults for now. This example adapted from the PEP defines a default for `BotT`: ```python from typing import Generic from typing_extensions import TypeVar class Bot: ... BotT = TypeVar("BotT", bound=Bot, default=Bot) class Context(Generic[BotT]): bot: BotT class MyBot(Bot): ... # type is Bot (the default) reveal_type(Context().bot) # type is MyBot reveal_type(Context[MyBot]().bot) ``` #### Type-checking Improvements * Fix missing type store for overloads (Marc Mueller, PR [16803](https://github.com/python/mypy/pull/16803)) * Fix `'WriteToConn' object has no attribute 'flush'` (Charlie Denton, PR [16801](https://github.com/python/mypy/pull/16801)) * Improve TypeAlias error messages (Marc Mueller, PR [16831](https://github.com/python/mypy/pull/16831)) * Support narrowing unions that include `type[None]` (Christoph Tyralla, PR [16315](https://github.com/python/mypy/pull/16315)) * Support TypedDict functional syntax as class base type (anniel-stripe, PR [16703](https://github.com/python/mypy/pull/16703)) * Accept multiline quoted annotations (Shantanu, PR [16765](https://github.com/python/mypy/pull/16765)) * Allow unary + in `Literal` (Jelle Zijlstra, PR [16729](https://github.com/python/mypy/pull/16729)) * Substitute type variables in return type of static methods (Kouroche Bouchiat, PR [16670](https://github.com/python/mypy/pull/16670)) * Consider TypeVarTuple to be invariant (Marc Mueller, PR [16759](https://github.com/python/mypy/pull/16759)) * Add `alias` support to `field()` in `attrs` plugin (Nikita Sobolev, PR [16610](https://github.com/python/mypy/pull/16610)) * Improve attrs hashability detection (Tin Tvrtković, PR [16556](https://github.com/python/mypy/pull/16556)) #### Performance Improvements * Speed up finding function type variables (Jukka Lehtosalo, PR [16562](https://github.com/python/mypy/pull/16562)) #### Documentation Updates * Document supported values for `--enable-incomplete-feature` in "mypy --help" (Froger David, PR [16661](https://github.com/python/mypy/pull/16661)) * Update new type system discussion links (thomaswhaley, PR [16841](https://github.com/python/mypy/pull/16841)) * Add missing class instantiation to cheat sheet (Aleksi Tarvainen, PR [16817](https://github.com/python/mypy/pull/16817)) * Document how evil `--no-strict-optional` is (Shantanu, PR [16731](https://github.com/python/mypy/pull/16731)) * Improve mypy daemon documentation note about local partial types (Makonnen Makonnen, PR [16782](https://github.com/python/mypy/pull/16782)) * Fix numbering error (Stefanie Molin, PR [16838](https://github.com/python/mypy/pull/16838)) * Various documentation improvements (Shantanu, PR [16836](https://github.com/python/mypy/pull/16836)) #### Stubtest Improvements * Ignore private function/method parameters when they are missing from the stub (private parameter names start with a single underscore and have a default) (PR [16507](https://github.com/python/mypy/pull/16507)) * Ignore a new protocol dunder (Alex Waygood, PR [16895](https://github.com/python/mypy/pull/16895)) * Private parameters can be omitted (Sebastian Rittau, PR [16507](https://github.com/python/mypy/pull/16507)) * Add support for setting enum members to "..." (Jelle Zijlstra, PR [16807](https://github.com/python/mypy/pull/16807)) * Adjust symbol table logic (Shantanu, PR [16823](https://github.com/python/mypy/pull/16823)) * Fix posisitional-only handling in overload resolution (Shantanu, PR [16750](https://github.com/python/mypy/pull/16750)) #### Stubgen Improvements * Fix crash on star unpack of TypeVarTuple (Ali Hamdan, PR [16869](https://github.com/python/mypy/pull/16869)) * Use PEP 604 unions everywhere (Ali Hamdan, PR [16519](https://github.com/python/mypy/pull/16519)) * Do not ignore property deleter (Ali Hamdan, PR [16781](https://github.com/python/mypy/pull/16781)) * Support type stub generation for `staticmethod` (WeilerMarcel, PR [14934](https://github.com/python/mypy/pull/14934)) ------------------------------------------------------------------- Tue Jan 2 17:24:56 UTC 2024 - Dirk Müller <dmueller@suse.com> - update to 1.8.0: * https://mypy-lang.blogspot.com/2023/12/mypy-18-released.html * https://mypy-lang.blogspot.com/2023/11/mypy-17-released.html * https://mypy-lang.blogspot.com/2023/10/mypy-16-released.html - fix dependencies ------------------------------------------------------------------- Wed Aug 30 18:31:19 UTC 2023 - Martin Schreiner <martin.schreiner@suse.com> - Update to 1.5.1: - stubtest: Fix __mypy-replace false positives. - Update typing_extensions stubs. - Update test suite dependencies: - types_psutil_version 5.9.5.15 -> 5.9.5.16 - types_setuptools_version 68.0.0.2 -> 68.0.0.1 - Rename package from mypy to python-mypy. - Rename .spec, .changes and rpmlintrc files, accordingly. - Adjust rpmlintrc. ------------------------------------------------------------------- Sun Aug 13 06:30:29 UTC 2023 - Sebastian Wagner <sebix@sebix.at> - update to version 1.5.0: - Drop Support for Python 3.7 - Mypy no longer supports running with Python 3.7, which has reached end-of-life. This was contributed by Shantanu (PR 15566). - Optional Check to Require Explicit @override - If you enable the explicit-override error code, mypy will generate an error if a method override doesn’t use the @typing.override decorator (as discussed in PEP 698). This way mypy will detect accidentally introduced overrides. - You can enable the error code via --enable-error-code=explicit-override on the mypy command line or enable_error_code = explicit-override in the mypy config file. - The override decorator will be available in typing in Python 3.12, but you can also use the backport from a recent version of typing_extensions on all supported Python versions. - More Flexible TypedDict Creation and Update - Mypy was previously overly strict when type checking TypedDict creation and update operations. Though these checks were often technically correct, they sometimes triggered for apparently valid code. These checks have now been relaxed by default. You can enable stricter checking by using the new --extra-checks flag. - Deprecated Flag: --strict-concatenate - The behavior of --strict-concatenate is now included in the new --extra-checks flag, and the old flag is deprecated. - Optionally Show Links to Error Code Documentation - If you use --show-error-code-links, mypy will add documentation links to (many) reported errors. The links are not shown for error messages that are sufficiently obvious, and they are shown once per error code only. - Consistently Avoid Type Checking Unreachable Code - If a module top level has unreachable code, mypy won’t type check the unreachable statements. This is consistent with how functions behave. The behavior of --warn-unreachable is also more consistent now. - Experimental Improved Type Inference for Generic Functions - You can use --new-type-inference to opt into an experimental new type inference algorithm. It fixes issues when calling a generic functions with an argument that is also a generic function, in particular. This current implementation is still incomplete, but we encourage trying it out and reporting bugs if you encounter regressions. We are planning to enable the new algorithm by default in a future mypy release. - Partial Support for Python 3.12 - Mypy and mypyc now support running on recent Python 3.12 development versions. Not all new Python 3.12 features are supported, and we don’t ship compiled wheels for Python 3.12 yet. - Improvements to Dataclasses - Improve signature of dataclasses.replace (Ilya Priven, PR 14849) - Fix dataclass/protocol crash on joining types (Ilya Priven, PR 15629) - Fix strict optional handling in dataclasses (Ivan Levkivskyi, PR 15571) - Support optional types for custom dataclass descriptors (Marc Mueller, PR 15628) - Add __slots__ attribute to dataclasses (Nikita Sobolev, PR 15649) - Support better __post_init__ method signature for dataclasses (Nikita Sobolev, PR 15503) - Mypyc Improvements - Support unsigned 8-bit native integer type: mypy_extensions.u8 (Jukka Lehtosalo, PR 15564) - Support signed 16-bit native integer type: mypy_extensions.i16 (Jukka Lehtosalo, PR 15464) - Define mypy_extensions.i16 in stubs (Jukka Lehtosalo, PR 15562) - Document more unsupported features and update supported features (Richard Si, PR 15524) - Fix final NamedTuple classes (Richard Si, PR 15513) - Use C99 compound literals for undefined tuple values (Jukka Lehtosalo, PR 15453) - Don't explicitly assign NULL values in setup functions (Logan Hunt, PR 15379) - Stubgen Improvements - Teach stubgen to work with complex and unary expressions (Nikita Sobolev, PR 15661) - Support ParamSpec and TypeVarTuple (Ali Hamdan, PR 15626) - Fix crash on non-str docstring (Ali Hamdan, PR 15623) - Documentation Updates - Add documentation for additional error codes (Ivan Levkivskyi, PR 15539) - Improve documentation of type narrowing (Ilya Priven, PR 15652) - Small improvements to protocol documentation (Shantanu, PR 15460) - Remove confusing instance variable example in cheat sheet (Adel Atallah, PR 15441) - Other Notable Fixes and Improvements - Constant fold additional unary and binary expressions (Richard Si, PR 15202) - Exclude the same special attributes from Protocol as CPython (Kyle Benesch, PR 15490) - Change the default value of the slots argument of attrs.define to True, to match runtime behavior (Ilya Priven, PR 15642) - Fix type of class attribute if attribute is defined in both class and metaclass (Alex Waygood, PR 14988) - Handle type the same as typing.Type in the first argument of classmethods (Erik Kemperman, PR 15297) - Fix --find-occurrences flag (Shantanu, PR 15528) - Fix error location for class patterns (Nikita Sobolev, PR 15506) - Fix re-added file with errors in mypy daemon (Ivan Levkivskyi, PR 15440) - Fix dmypy run on Windows (Ivan Levkivskyi, PR 15429) - Fix abstract and non-abstract variant error for property deleter (Shantanu, PR 15395) - Remove special casing for "cannot" in error messages (Ilya Priven, PR 15428) - Add runtime __slots__ attribute to attrs classes (Nikita Sobolev, PR 15651) - Add get_expression_type to CheckerPluginInterface (Ilya Priven, PR 15369) - Remove parameters that no longer exist from NamedTuple._make() (Alex Waygood, PR 15578) - Allow using typing.Self in __new__ with an explicit @staticmethod decorator (Erik Kemperman, PR 15353) - Fix self types in subclass methods without Self annotation (Ivan Levkivskyi, PR 15541) - Check for abstract class objects in tuples (Nikita Sobolev, PR 15366) - Typeshed Updates - Typeshed is now modular and distributed as separate PyPI packages for everything except the standard library stubs.

Previously these were heap-allocated Python objects. Native floats are faster and use less memory. Code that uses floating-point operations heavily can be several times faster when using native floats. - Various float operations and math functions also now have optimized implementations. Refer to the documentation for a full list. - This can change the behavior of existing code that uses subclasses of float. When assigning an instance of a subclass of float to a variable with the float type, it gets implicitly converted to a float instance when compiled - Previously, implicit conversions were applied to int subclasses but not float subclasses. - Also, int values can no longer be assigned to a variable with type float in compiled code, since these types now have incompatible representations. An explicit conversion is required. - This restriction only applies to assignments, since they could otherwise narrow down the type of a variable from float to int. int values can still be implicitly converted to float when passed as arguments to functions that expect float values. - Note that mypyc still doesn’t support arrays of unboxed float values. Using list[float] involves heap-allocated float objects, since list can only store boxed values. Support for efficient floating point arrays is one of the next major planned mypyc features. - Related changes: - Use a native unboxed representation for floats (Jukka Lehtosalo, PR 14880) - Document native floats and integers (Jukka Lehtosalo, PR 14927) - Fixes to float to int conversion (Jukka Lehtosalo, PR 14936) - Mypyc: Native Integers - Mypyc now supports signed 32-bit and 64-bit integer types in addition to the arbitrary-precision int type. You can use the types mypy_extensions.i32 and mypy_extensions.i64 to speed up code that uses integer operations heavily. - Refer to the documentation for more information.

It will be still possible to target Python 3.6 using --python-version in future mypy versions, but no bugs will be fixed that affect only Python 3.6 (unless they are regressions). Also note that typeshed just recently dropped Python 3.6 support, so standard library features only available in Python 3.6 will not be supported. on https://mypy-lang.blogspot.com/2022/07/mypy-0971-released.html - Mypyc Improvements and Fixes * Speed up accessing always defined native attributes (Jukka Lehtosalo, PR 12600) * Reduce the overhead of reference counting (Jukka Lehtosalo, PR 12805, PR 12810, PR 12817) * Fix Python 3.11 C API errors (97littleleaf11, PR 12850) * Generate smaller code for casts and some implicit type coercions (Jukka Lehtosalo, PR 12839) * Optimize calling Python objects with zero or one arguments (97littleleaf11, PR 12862) * Replace integer floor division by a power of two with a shift (Jukka Lehtosalo, PR 12870) * Add primitives for faster access of float and tuple type objects (Richard Si, PR 13078) * Fix compile error related to operator assignment in a generator function (Zsolt Dollenstein, PR 13144) - Stubtest Improvements * Allow ellipsis as default argument (Shantanu, PR 12838) * Support --version (Shantanu, PR 12852) * Check type variables and ParamSpecs (Shantanu, PR 12851) * Add error summary and other output tweaks (KotlinIsland, PR 12855) - Other Notable Fixes and Improvements * Disallow assignments to awaited coroutines that do not return (Shantanu, PR 12853) * Search sys.path for PEP 561 compliant packages (Ashley Whetter, PR 11143) * Treat generators with await as async (Jared Hance, PR 12925) * Fix bug in constraints solver regarding ParamSpec upper bounds (Alex Waygood, PR 12938) * Fix crash on redefined class variable annotated with Final[<type>] (Alex Waygood, PR 12951) * Improve handling of overloads with ParamSpec (Alex Waygood, PR 12953) * Don’t suggest installing types packages for some third-party packages that now include types or are obsolete (Shantanu, PR 12959) * Add a short note when an error may be fixed by adding an await (Ivan Levkivskyi, PR 12958) * Support unannotated converters for attr.ib (t4lz, PR 12815) * Disallow undesirable implicit reexport with a from import (Shantanu, PR 12704) * Fix crash when subclass method has the same name as a type alias (Wesley Collin Wright, PR 13015) * Include end column offset in the mypy AST (bruno messias, PR 12972) * Fix "attribute 'arguments' of 'FuncDef' undefined" incremental crash (Frédéric Perrin, PR 12324) * Fix false positive error on multiple enum base classes (Alex Waygood, PR 12963) * Don't add __match_args__ for dataclasses and named tuples on Python versions lower than 3.10 (Stanislav K, PR 12503) * Fix crash when overriding partial-type attribute with method (Jake Lishman, PR 12943) * Fix editable installs to current working directory (Shantanu, PR 13161) - Typeshed is now modular and distributed as separate PyPI packages for everything except the standard library stubs. Please see git log for full list of typeshed changes. ------------------------------------------------------------------- Tue Jun 21 09:00:36 UTC 2022 - Sebastian Wagner <sebix+novell.com@sebix.at> - remove obsolete patch 12452-stringent-err-msg.patch - update to version 0.960: - Recognise typing.LiteralString and typing_extensions.LiteralString as aliases to str. - This does not add proper support for LiteralString, but this allows it to be used in type annotations and stubs. LiteralString will be included in Python 3.11 (PEP 675), and it can be used to require that a value is an arbitrary literal string (once fully supported). - Per-file Timing Stats - When mypy is run with the (currently hidden) --timing-stats FILE option, mypy will record detailed information about time spent type checking each file (microseconds). When profiling mypy runs over a large codebase, it can be useful to know which files are the slowest to type check. We are happy to receive bug reports about unexpectedly slow type checking. - Performance Improvements - Cache type of container literals when possible (Hugues, PR 12707) - Speed up type checking of nested if expressions (Hugues, PR 12700) - Speed up type checking of container literals with tuple entries (Hugues, PR 12706) - Speed up argument count check (Hugues, PR 12703) - Speed up processing large error counts and improve error filtering (Hugues, PR 12631) - Experimental Fast Module Lookup - Use the new --fast-module-lookup to switch to an alternative import resolution implementation that is faster when a large number of folders share a top-level namespace. We’d like to hear if you notice an improvement when using this flag, so that we can potentially prioritize work to enable this by default. - Documentation Updates - Add information about classes and types to “Getting started” (Michael Lee, PR 6557) - Mention no_type_check decorator in documentation (Shantanu, PR 12713) - Remove most mentions of type comments from docs (Shantanu, PR 12683) - Use PEP 585 syntax in "The type of class objects" (Alex Waygood, PR 12516) - Improvements to Plugin System - Add a class attribute hook to the plugin system (Danny Weinberg, PR 9881) - Add an alternative class decorator hook that is less error-prone than the old one (Jukka Lehtosalo, PR 12762) - ParamSpec Improvements - Friendlier errors for ParamSpec (PEP 612) (Shantanu, PR 12832) - Fix ParamSpec crash related to Any types (EXPLOSION, PR 12548) - Use tuple[object, ...] and dict[str, object] as upper bounds for ParamSpec.args and ParamSpec.kwargs (Alex Waygood, PR 12668) - Fixes to Crashes - Fix crash on invalid Python executable (Pranav Rajpal, PR 12812) - Fix crash on type alias definition inside dataclass declaration (Alex Waygood, PR 12792) - Fix crash related to namedtuple in unannotated function (Jukka Lehtosalo, PR 12804) - Fix nested namedtuple crash in incremental mode (Jukka Lehtosalo, PR 12803) - Fix forward references and generic inheritance in attrs classes (Jukka Lehtosalo, PR 12772) - mypyc: Fix TypeError in lambda argument to overloaded function (Jukka Lehtosalo, PR 12780) - Fix crashes related to functools.total_ordering and forward references (Jukka Lehtosalo, PR 12767) - Fix crashes related to dataclasses and forward references (Jukka Lehtosalo, PR 12762) - Fix crash on invalid TypedDict definition (Alex Waygood, PR 12741) - Fix crash when using decorator in class scope (dzcode, PR 12724) - Other Notable Fixes and Improvements - Fix type annotation support of dunder methods in stubgen (Fabian Keller, PR 12828) - Fix some value patterns in match statements to be non-exhaustive (Štěpán Horáček, PR 12751) - Generate error when using both abstractmethod and final (Tomoki Nakagawa, PR 12743) - Add more precise error message for Callable annotation (frerikandriessen, PR 12518) - Fix generic inference in functions with TypeGuard (Nikita Sobolev, PR 11797) - Add check if python_version was parsed as float in pyproject.toml (Marcel Otoboni, PR 12558) - Fix nested overload merging (Marc Mueller, PR 12607) - stubtest: Generate error if type alias doesn't exist at runtime (Alex Waygood, PR 12608) - Support typing_extensions.overload (Jelle Zijlstra, PR 12602) - update to version 0.950: - Recent third-party library stubs available via types-* packages (e.g. types-requests) are actively using recent typing features that may not be supported by older mypy releases. We recommend that if you pin mypy to a specific version, you should also pin any stub packages to a version no more recent than the mypy release. Otherwise the mypy version you use may silently fall back to Any types if it encounters annotation syntax that it can’t process. It’s fine to continue using older versions of stubs when you upgrade mypy. - Note also that recent versions of many third-party stub packages don’t support Python 2 any more. If you are using mypy to type check Python 2 code, it’s important to pin all stub packages to versions that still support Python 2. Generally stub package versions: in Feb 2022 or earlier still support Python 2 (assuming that they supported Python 2 at all). - New Features: Concatenate and Literals with ParamSpec - It’s now possible to precisely annotate decorators that add/remove arguments, using ParamSpec together with typing.Concatenate (Python 3.10 or later) or typing_extensions.Concatenate. The decorator in this example provides an implicit Request argument to the decorated function. - New Feature: Detect Unused Coroutines and Awaitables - Now mypy will give an error if you forget to await a coroutine: - If you enable the unused-awaitable error code, mypy will also complain about any unused value that supports __await__. This is not enabled by default, since this can cause false positives. - New Feature: assert_type - You can now use typing_extensions.assert_type to ask mypy to validate that an expression has a specific static type. Mypy will report an error if the inferred type is not as expected: - from typing_extensions import assert_type - assert_type([1], list[int]) # OK - # Error: Expression is of type "List[int]", not "List[str]" - assert_type([1], list[str]) - This can be used to validate that the expected type is inferred by mypy when calling a complex overloaded function, for example. At runtime assert_type just returns the first argument and doesn’t perform a runtime type check. - Mypyc Fixes and Improvements - Fix overflow in id built-in (Ekin Dursun, PR 12332) - Simplify generated code for native attribute get (Jukka Lehtosalo, PR 11978) - Implement close method for generators (Max Shvets, PR 12042) - Use more accurate flags with msvc (KotlinIsland, PR 12468) - Fix potential memory leak with setdefault() (Jukka Lehtosalo, PR 12514) - Make boxed integer constants/literals faster (Jukka Lehtosalo, PR 12507) - Performance Improvements - Mypy now type checks somewhat faster, in particular when dealing with enums and unions with many items. - Speed up union types (Jukka Lehtosalo, PR 12541, PR 12519) - Speed up subtype checks (Jukka Lehtosalo, PR 12540, PR 12538, PR 12536, PR 12539) - Speed up type checking enums (Hugues, PR 12032) - Speed up union types further (Hugues, PR 12630) - Documentation Improvements - Use Furo theme for documentation (97littleleaf11, PR 12348) - Add missing enable_error_code to config documentation (Mathieu Kniewallner, PR 12346) - Correct example in “Annotation issues at runtime” (Alex Waygood, PR 12356) - Fix inaccuracy: NoneType is exposed in the types module on Python 3.10+ (Alex Waygood, PR 12515) - Stubgen Improvements - Fix handling of Protocol (citruz, PR 12129) - Use _typeshed.Incomplete instead of typing.Any (Sebastian Rittau, PR 12449) - Do not consider nested generators (Štěpán Horáček, PR 12463) - Fix behavior for instance variables in C extensions (Shubham SInghal, PR 12524) - Stubtest Improvements - Generate error for read-only property at runtime, but not in stub (Alex Waygood, PR 12291) - Enable verification of __match_args__ attributes (Alex Waygood, PR 12465) - Other Notable Fixes and Improvements - Use tomllib on Python 3.11 (Shantanu, PR 12305) - Print compilation status with --version (Shantanu, PR 12318) - Fix __annotations__ being undefined (Niklas Gustafsson, PR 10969) - Add success message for notes-only output (97littleleaf11, PR 12306) - dmypy: Warn instead of failing if report generation is configured (Nate McMaster, PR 10181) - Fix caching of PEP 561 namespace packages with missing submodules (Shantanu, PR 12250) - Fix empty reveal_locals output (Cibin Mathew, PR 12400) - Check that async for/with is inside an async function (Štěpán Horáček, PR 12418) - Recognize Hashable as a real protocol (Nikita Sobolev, PR 11802) - Remove the * for inferred types from reveal_type output (Stanislav K, PR 12459) - Unify a codepath in typevarlike semanal (Jared Hance, PR 12480) - Recognise both attrs and attr package names (Spencer Brown, PR 12469) - Fix Callable attributes in frozen dataclasses (Jordan Speicher, PR 12383) - Improve checking of __slots__ (Jukka Lehtosalo, PR 12531) - Avoid conflicts between type variables defined in different classes (Jukka Lehtosalo, PR 12590) - Fix __slots__ and __deletable__ in incremental mode (Jukka Lehtosalo, PR 12645) - Fix issue with ParamSpec serialization (Jukka Lehtosalo, PR 12654) - Fix types of inherited attributes in generic dataclasses (Jukka Lehtosalo, PR 12656) ------------------------------------------------------------------- Mon Mar 28 15:33:14 UTC 2022 - Matej Cepl <mcepl@suse.com> - Add 12452-stringent-err-msg.patch to make mypy work with more stringent error messages in Python >= 3.10.3 (gh#python/mypy#12451). ------------------------------------------------------------------- Fri Mar 25 21:32:58 UTC 2022 - Sebastian Wagner <sebix+novell.com@sebix.at> - Update to version 0.942: - Fixes to Regressions: - Let overload item have a more general return type than the implementation (Jukka Lehtosalo, PR 12435) - Fix inheritance false positives with dataclasses/attrs (Jukka Lehtosalo, PR 12411) - Support overriding dunder attributes in Enum subclass (Petter Friberg, PR 12138) - Fix small conditional overload regression (Marc Mueller, PR 12336) - Other Fixes: - Fix issues related to the order of processing in the builtins import cycle (Jukka Lehtosalo, PR 12431) - Fix crash in match statement if class name is undefined (Jukka Lehtosalo, PR 12417) - Allow non-final __match_args__ and overriding (Jukka Lehtosalo, PR 12415) ------------------------------------------------------------------- Mon Mar 14 21:44:08 UTC 2022 - Sebastian Wagner <sebix+novell.com@sebix.at> - Update to version 0.941: - No changelog available. ------------------------------------------------------------------- Mon Mar 14 21:35:28 UTC 2022 - Sebastian Wagner <sebix+novell.com@sebix.at> - Update to version 0.940: - Match Statement Mypy now has experimental support for type checking match statements introduced in Python 3.10. - Python 2 End-of-Life Schedule After this release, Python 2 support is in feature freeze. Mypy won’t add new features or fixes specific to type checking Python 2 code, expect for fixes of significant regressions. Mypy will drop Python 2 support in the second half of 2022. Important note: Since typeshed is in the process of removing Python 2 specific stubs, you should pin all installed typeshed stub packages for third-party libraries to a version from Feb 2022 or earlier if you want to type check Python 2 code. -

Previously this could only be configured at TypedDict level (by using total=). - You can also use typing_extensions.Required to mark an item as required in a non-total TypedDict. - New Feature: ParamSpec (Experimental) - Mypy now partially support ParamSpec, which was introduced in Python 3.10. This makes it possible to define type variables that range over the parameter specification of a callable type. In particular, it allows giving precise types for some decorators that change the return type of the decorated function. - Miscellaneous New Features - Define a GitHub Action that makes it easier to run mypy in GitHub CI workflows (Elvis Pranskevichus, PR 11320) -

Fix signature in curses and corresponding dmypy bug (Shantanu, PR 11785) ------------------------------------------------------------------- Thu Dec 16 08:04:39 UTC 2021 - Sebastian Wagner <sebix+novell.com@sebix.at> - Update to version 0.920: - Making a Variable Optional in an Else Block - Now mypy alllows more general conditionally defined variables with optional types. Previously mypy allowed this only if a None assignment happened first. Now this is also supported. Implemented by Michael J. Sullivan in PR 11002. - Type Checking __slots__ Assignment - For classes that define the special __slots__ attribute, mypy will now report an error on assigning to attributes that are not found in the slots definitions (this matches runtime semantics). - Note that this feature does not work for dynamically computed slots. Implemented by Nikita Sobolev in PR 10864. - Partial Python 3.10 Support - We now ship binary wheels for Python 3.10 and mypy supports the new Python 3.10 union type syntax. - Some new features, including the match statement, ParamSpec and TypeAlias are not supported yet. - Python 3.5 Is No Longer Supported - Python 3.5 reached its end of life more than a year ago. Its support was deprecated in mypy 0.910 and it is no longer supported in mypy 0.920. - Efficient String and Bytes Formatting in Mypyc - Most string and bytes formatting methods now use fast C-level logic when compiled with mypyc. This includes % formatting, the format() method, and f-strings. This was implemented by 97littleleaf11 as part of a Google Summer of Code project. - Work Towards singledispatch Support - The signature of the initial function variant handles the generic case and describes the external signature of the singledispatch function. - This was implemented Pranav Rajpal as part of a Google Summer of Code project. - Stubgen Improvements - Add support for yield statements in stubgen (Sebastian Rittau, PR 10745) - Handle commas in namedtuple field definition in stubgen (Vanessa Ung, PR 10828) - Other Notable Fixes and Improvements - Allow plugin signature hooks to return FunctionLike (to support overloads) (pranavrajpal, PR 10717) - Narrow type with type variable when the upper bound is a subtype of current type (ethframe, PR 10658) - Make --cache-fine-grained imply --local-partial-types (Michael J.

We received feedback that this wasn’t a good fit for all use cases, since it asks for interactive confirmation from the user, and it requires another mypy invocation to actually perform type checking. - This release adds the new option --non-interactive that can be used with --install-types to install suggested stub packages without asking for confirmation. This can be useful in Continuous Integration jobs. The option causes mypy to both install stub packages and perform type checking within a single invocation. When not using --non-interactive, you’d have to run mypy again to get up-to-date results with the installed stubs. - This option provides a new way to migrate existing mypy runner scripts after updating to mypy 0.9xx: just add the --install-types --non-interactive options to your mypy command line. - Note that --install-types currently always installs the latest stubs for all supported packages. If you want reproducible results from your builds, we recommend explicitly pinning stub package versions in your requirements.txt file, for example. - Python 3.5 Deprecation - Running mypy on Python 3.5 is now deprecated. A future mypy release will drop Python 3.5 support. We haven’t decided when this will happen, but this might happen in the next feature release after 0.910. - Stubgen Improvements - Don't annotate unknown argument and return types (Sebastian Rittau, PR 10626) - Never generate a variable initializer (Sebastian Rittau, PR 10623) - Use NamedTuple class syntax (Sebastian Rittau, PR 10625) - Use T | None (PEP 604) instead of Optional[T] (Sebastian Rittau, PR 10624) - Other Fixes and Improvements - Fix some crashes from faulty casts (Shantanu, PR 10560) - Update docs for deferral of PEP 563 to 3.11 (Smart, PR 10655) - Don't suggest to install stubs for packages with py.typed files (Sebastian Rittau, PR 10652) - Correct the type package name of pyopenssl ( Sebastian Rittau, PR 10656) - Improve error reporting when --install-types has no cache (PR 10667) - Suggest types-setuptools for pkg_resources (Sebastian Rittau, PR 10681) - Fix crash with assignment to variable guarded with TypeGuard (PR 10683) - Don't ask to install a stub package if stubs are installed (PR 10670) - Fix crash when inferring multiple assignment with overloaded function (PR 10689) - update to version 0.900: - Third-party Library Stubs in Stub Packages (Breaking Change) - Mypy now only ships with type stubs for stdlib modules (plus typing_extensions and mypy_extensions). If you use third-party libraries that don’t include stubs or inline type annotations, you can explicitly install stub packages, usually called types-<name>. - You can also now run mypy --install-types to install all missing stub packages in the mypy run (or the previous run, if you don’t pass any files to check). - Using cached types_requests-0.1.8-py2.py3-none-any.whl (22 kB) - For more information, read the blog post about this change and why we did this. There is more detail in the docs. - Python 2 Support is Opt-in (Breaking Change) - If you want to type check Python 2 code, you now have to install mypy[python2] using pip (on Python 3.8 and later): - python3 -m pip install -U mypy[python2] - This will install the additional typed-ast pip dependency that is required for Python 2 support. Type checking Python 2 code is still fully supported by mypy. - TypeGuard - Mypy now supports defining user-defined functions that perform type narrowing, similar to isinstance. Read PEP 647 for the details. - Since TypeGuard will be included in Python 3.10, which hasn’t been released yet, you will have to import it from a recent version of typing_extensions for now. - Support for pyproject.toml - Binary Wheels for Apple Silicon - We now include binary wheels for Apple Silicon. This can make mypy runs over 4x faster on supported hardware. This requires a native Apple Silicon build of Python 3.9 to work. - Type Narrowing with type(x) - Hosted Documentation for Mypyc - We now have hosted user documentation for mypyc, the compiler we use to speed up mypy. Mypyc is still experimental, but we are looking for early adopters. - New Mypyc Features - Support __setitem__, __delitem__, __len__ and __contains__ in native classes (PR 10451) - Basic support for class-based named tuples (PR 10252) -

Two new Python features improve this situation and are now supported by mypy: PEP 585 lets you use list[int] instead of List[int] (no need to import List and other generic collections from typing). PEP 604 lets you write X | Y instead of Union[X, Y], and X | None instead of Optional[X] (no need to import Union or Optional from typing). Note: Using list[int] requires Python 3.9 and X | Y requires Python 3.10 (alpha) in order to work at runtime. To use them on older versions of Python, use from __future__ import annotations. This allows them to be used in type annotations, but the older variants (or string literal escaping) may be required in non-annotation contexts, such as in type aliases. See the docs for more details. Here is an example that uses the new features: from __future__ import annotations def fields(s: str | None) -> list[str]: if not s: return [] else: return s.split(',') These were implemented by Allan Daemon in PR 9564 and by Marc Mueller in PR 9647. - Improvements to Finding Modules This release adds several improvements to how mypy finds Python source files to type check. You can now pass paths to files within namespace packages on the command line, and mypy can better infer their module names. As before, use --namespace-packages to enable namespace packages. When you use --explicit-package-bases together with --namespace-packages, mypy assumes that only the current directory and directories explicitly specified in MYPYPATH (or mypy_path in the config file) are valid package roots. This can help with situations where the module name of a file is ambiguous. For example, it may not be clear whether src/pkg/mod.py should be treated as src.pkg.mod or pkg.mod, and you can use this option to disambiguate between the two (more information in the docs). The above improvements were implemented in PR 9742 by Shantanu.

Previously mypy daemon did not support this, and it was necessary to use --follow-imports and explicitly mention all files to check on the command line. (Following imports in mypy daemon is an experimental feature.) See the docs about following import in mypy. - Miscellaneous New Features: - Support environment variable interpolation for junit_xml configuration key (Mattwmaster58, PR 8479) - Add no_site_packages config file setting (davidzwa, PR 8524) - Allow .mypy.ini (with a dot prefix) as an alternative name to mypy.ini (dosisod, PR 8515) - Disallow unpacking of strings in multiple assignment, as this is usually a bug (Abtin, PR 8589) - Allow type aliases in a runtime (non-type) context (PR 8779) - Add narrowing unions with bool literals via identity check (Steve Dignam, PR 8821) - Always allow to cast to Any without warnings (oda, PR 8544) - Suggest solutions for a typo in a key of a TypedDict (Felicián Németh, PR 8483) - Provide more context about why incompatible with supertype is an error (Chetan Khanna, PR 8866) - Other Notable Improvements and Bug Fixes: - Fix handling dependencies to __call__ in mypy daemon (PR 8494) - Various improvements to stubtest (PR 8502, PR 8886) (Shantanu) - Fix invalid type causing named tuple errors reported in wrong files (PR 8549) - Clarify documentation of Liskov substitution principle (PR 8563) - Fix type inference with lambda that returns None (PR 8562) - Fix incremental crash bug caused by NewType in functions (PR 8607) - Fix indexed assignment check when TypedDict is used as upper bound (Xuanda Yang, PR 8621) - Improve error message for bad indexed assignment (pando, PR 8641) - Fix crash when the same file is processed under multiple names (PR 8644) - Fix parser when using Python 3.9 (PR 8716) - Accept dict() as an empty dictionary in a TypedDict context (PR 8749) - Fix incorrect coroutine return type for nested function (Jens Widell, PR 8741) - Reject bytes literal as a TypedDict key (PR 8782) - Allow attrs keyword-only arguments at any position (Markus Schmaus, PR 8803) - Detect duplicate keys in call-based TypedDict definitions (PR 8849) - Look at arguments when generating constraints for an overload (PR 8845) - Fix potential wrong-file error message for unsupported types (PR 8854) - Typeshed Updates - Many small improvements were made to typeshed — too many to list. Browse the typeshed commit log here. - update to version 0.770: - Tagged Unions - Previously, the only way to distinguish between two types in a union was to use an isinstance check. Now, mypy supports distinguishing between two or more types based on the value of some common shared "tag" field. This feature is most useful when you want to narrow down a union of TypedDicts: since TypedDicts are really just regular dicts at runtime, using isinstance checks won't work. Instead, you can now label or tag each TypedDict with a distinct Literal type and discriminate by checking that tag. Note that you can import Literal from typing_extensions on Python 3.7 and earlier. You can also use this technique to discriminate between unions of objects, tuples, or named tuples, so long as: 1. Every item in your union is tagged with a unique value 2. Mypy understands how to narrow the union of the tag values. For more details and examples, see the documentation on tagged unions. - Type Inference Improvements Type inference is now more powerful. Mypy can infer types in some cases where you previously needed an explicit type annotation. Mypy can infer a built-in collection type from augmented assignment statements. Some dictionary construction idioms are better supported. Mypy is better at inferring defaultdict types. - Multiple Inheritance and isinstance() Checks Previously, mypy assumed a variable cannot have two unrelated types when analyzing isinstance checks. For example, in the following example B is not a subclass of A, so mypy would incorrectly conclude the isinstance check is always false, and that the if-branch is unreachable — even though var could actually be a subtype of both types. This meant that mypy skipped type checking anything inside the if statement, since it (by design) skips analyzing unreachable branches. Now, mypy will instead decide that the narrowed type of x is test.<subclass of "A" and "B">, instead of marking the branch as unreachable. If it’s impossible for two types to be a subtype of one another, mypy will continue to not attempt to infer this "ad-hoc intersection". - Other Notable Improvements and Bug Fixes: - Fix some crash bugs involving import * and import cycles (PR 8450) - Fix interaction of descriptor methods with plugins (Jan Verbeek, PR 8365) - Allow strict in config file (Ville Skyttä, PR 8192) - Don’t crash when a module shadows builtin libraries (such as typing or types, PR 8405) - Fix type join between subclasses of unicode and str (PR 8402) - Fix type join of fixed-length tuples with mismatching lengths (Marti Raudsepp, PR 8333) - Fix type join of Sequence (e.g. variadic tuple) and fixed-length tuple (Marti Raudsepp, PR 8335) - Make mypy.api.run_dmypy actually capture the output (PR 8375) - Support determining whether a literal is truthy (Jan Verbeek, PR 8368) - Fix covariant overriding of decorated methods (Xuanda Yang, PR 8350) - Support typing.Annotated in addition to typing_extensions.Annotated (Jakub Stasiak, PR 8371) - Add add_method_to_class function to plugins.common (useful when writing mypy plugins) (Maksim Kurnikov, PR 8245) - Fix module alias as instance attribute (Uwe L.

It got a complete rewrite. Some features of the new stubtest are: - Find missing, extraneous or mistyped classes, methods, functions and attributes in the stubs - Check presence, names and kinds of function arguments, accounting for overloads, decorators, *args and kwargs. Checks argument types against their default values, accounting for type vars. - Checks @property, @classmethod, @staticmethod declarations - Check types of module level and class level attributes and enums - Some results of this: - We now run stubtest in typeshed CI (for stdlib) - We’ve fixed about 1900 issues in typeshed definitions - We’ve greatly improved Python 3.8 support in typeshed and it’ll be easier to make the changes needed for future Python versions - We’ve uncovered a handful of issues in Python itself - Typeshed Updates: - Many small improvements were made to typeshed — too many to list.
