Version 6.3.1 — 2022-02-01

• Fix: deadlocks could occur when terminating processes. Some of these deadlocks (described in issue 1310_) are now fixed.

• Fix: a signal handler was being set from multiple threads, causing an error: "ValueError: signal only works in main thread". This is now fixed, closing issue 1312_.

• Fix: --precision on the command-line was being ignored while considering --fail-under. This is now fixed, thanks to Marcelo Trylesinski <pull 1317_>_.

• Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython internal fields which are moving during the alpha phase. Fixes issue 1316_.

Version 6.3 — 2022-01-25

• Feature: Added the lcov command to generate reports in LCOV format. Thanks, Bradley Burns <pull 1289_>. Closes issues 587 <issue 587_> and 626 <issue 626_>_.

• Feature: the coverage data file can now be specified on the command line with the --data-file option in any command that reads or writes data. This is in addition to the existing COVERAGE_FILE environment variable. Closes issue 624. Thanks, Nikita Bloshchanevich <pull 1304_>.

• Feature: coverage measurement data will now be written when a SIGTERM signal is received by the process. This includes :meth:Process.terminate <python:multiprocessing.Process.terminate>, and other ways to terminate a process. Currently this is only on Linux and Mac; Windows is not supported. Fixes issue 1307_.

• Dropped support for Python 3.6, which reached end-of-life on 2021-12-23.

• Updated Python 3.11 support to 3.11.0a4, fixing issue 1294_.

• Fix: the coverage data file is now created in a more robust way, to avoid problems when multiple processes are trying to write data at once. Fixes issues 1303 <issue 1303_>_ and 883 <issue 883_>_.

Published 1.1.272

Enhancement: Added bidirectional type inference support for comprehension statements that create generators. This addresses microsoft/pyright#3948.

Bug Fix: Improved handling of circular dependencies in a generic class hierarchy — in particular, where a class is parameterized by a constrained TypeVar where one of the constraints includes the class or its ancestors. This addresses microsoft/pyright#3955.

Bug Fix: Fixed false positive reportInvalidTypeVarUse diagnostic in an overload implementation. This addresses microsoft/pyright#3958.

Bug Fix: Fixed confusing error message when a value is written to a class attribute that is not defined on the class but is defined on the metaclass but with an incompatible type. This addresses microsoft/pyright#3960.

Enhancement: Updated typeshed stubs to the latest version.

Enhancement: Improved error message readability for generic class type incompatibilities.

Bug Fix: Fixed a bug that resulted in incorrect type evaluation when calling a generic class constructor from within that class implementation. This addresses microsoft/pyright#3927.

Bug Fix: Fixed recent regression. Default includes/excludes should be used when pyproject.toml is present. This addresses #3965.

Enhancement: Extended support for method override completions that use member access expression forms in a parameter's default value expression. This addresses microsoft/pylance-release#3374.

Bug Fix: Fixed false positive error when a call expression provides zero arguments for an unpacked tuple of indeterminate length within a Callable. This addresses #3972.

Bug Fix: Improved error message for positional parameter count mismatch when the signature contains an unpacked tuple with either a definite or indefinite length.

v1.10.1 (2022-08-31)

• Add __hash__ method to pydancic.color.Color class, #4454 by @​czaki

Full Changelog: https://github.com/pydantic/pydantic/compare/v1.10.0...v1.10.1

v1.10.0 (2022-08-30)

See #4419 for feedback and discussion, docs are live at pydantic-docs.helpmanual.io.

• Refactor the whole pydantic dataclass decorator to really act like its standard lib equivalent. It hence keeps __eq__, __hash__, ... and makes comparison with its non-validated version possible. It also fixes usage of frozen dataclasses in fields and usage of default_factory in nested dataclasses. The support of Config.extra has been added. Finally, config customization directly via a dict is now possible, #2557 by @​PrettyWood BREAKING CHANGES:
  • The compiled boolean (whether pydantic is compiled with cython) has been moved from main.py to version.py
  • Now that Config.extra is supported, dataclass ignores by default extra arguments (like BaseModel)
• Fix PEP487 __set_name__ protocol in BaseModel for PrivateAttrs, #4407 by @​tlambert03
• Allow for custom parsing of environment variables via parse_env_var in Config, #4406 by @​acmiyaguchi
• Rename master to main, #4405 by @​hramezani
• Fix StrictStr does not raise ValidationError when max_length is present in Field, #4388 by @​hramezani

• Support Python 3.11, including binaries for 3.11 in PyPI, #4374 by @​samuelcolvin
• Add support for re.Pattern, #4366 by @​hramezani
• Fix __post_init_post_parse__ is incorrectly passed keyword arguments when no __post_init__ is defined, #4361 by @​hramezani
• Fix implicitly importing ForwardRef and Callable from pydantic.typing instead of typing and also expose MappingIntStrAny, #4358 by @​aminalaee
• remove Any types from the dataclass decorator so it can be used with the disallow_any_expr mypy option, #4356 by @​DetachHead
• moved repo to pydantic/pydantic, #4348 by @​yezz123
• fix "extra fields not permitted" error when dataclass with Extra.forbid is validated multiple times, #4343 by @​detachhead
• Add Python 3.9 and 3.10 examples to docs, #4339 by @​Bobronium
• Discriminated union models now use oneOf instead of anyOf when generating OpenAPI schema definitions, #4335 by @​MaxwellPayne
• Allow type checkers to infer inner type of Json type. Json[list[str]] will be now inferred as list[str], Json[Any] should be used instead of plain Json. Runtime behaviour is not changed, #4332 by @​Bobronium
• Allow empty string aliases by using a alias is not None check, rather than bool(alias), #4253 by @​sergeytsaplin
• Update ForwardRefs in Field.outer_type_, #4249 by @​JacobHayes
• The use of __dataclass_transform__ has been replaced by typing_extensions.dataclass_transform, which is the preferred way to mark pydantic models as a dataclass under PEP 681, #4241 by @​multimeric
• Use parent model's Config when validating nested NamedTuple fields, #4219 by @​synek
• Update BaseModel.construct to work with aliased Fields, #4192 by @​kylebamos

Published 1.1.229

Bug Fix: Fixed a bug that caused semantic highlighting to sometimes skip information for certain tokens involved in member access expressions.

Enhancement: Added checks for incompatible variable types for same-named instance or class variables in two base classes.

Enhancement: Updated typeshed stubs to the latest version.

Bug Fix: Fixed a bug that led to misleading type error messages and hover text when a type with an associated generic type alias was specialized. The underlying generic type was properly specialized, but the type alias itself appeared to be unspecialized still. Since the type alias is displayed in error messages and hover text, this was confusing.

Bug Fix: Fixed a bug where classes that derive from Any are not allowed to be assigned to a TypeVar. This resulted in a false positive error when returning NotImplemented in a function that is annotated to return a TypeVar.

Bug Fix: Fixed a bug that resulted in a false positive error "variable not in slots" when a value was assigned to a class variable that is a descriptor.

Bug Fix: Fixed a bug in the __post_init__ validation logic that resulted in a false positive when a dataclass with an InitVar derives from another dataclass with an InitVar.

Enhancement: Added support for per-line suppression of diagnostics using # pyright: ignore comment. This also supports rule-specific suppression using a list of diagnostic rules, as in # pyright: ignore [reportGeneralTypeIssues].

Bug Fix: Fixed a bug in the reportUnnecessaryComparison diagnostic rule that resulted in false negatives when one of the two operands included a None in the type.

Bug Fix: Fixed a bug that resulted in a false positive error when testing type compatibility of an invariant type argument that consists of a union of types, some of which are subtypes of each other.

Published 1.1.228

Bug Fix: Improved "reportUnnecessaryComparison" diagnostic check so it catches more cases.

Performance: Fixed performance bug that was causing a significant slowdown when evaluating highly nested call expressions especially when there are argument errors in the innermost expressions.

Enhancement: Extended support for narrowing of index expressions to include those with negative subscripts, such as a[-1]. This is supported for all supported type guard patterns.

Bug Fix: Fixed bug that resulted in a false positive error when using typing.Self in an inner function defined within an outer method.

Enhancement: Added negative type narrowing support for sequence patterns in match statements.

Bug Fix: Fixed a bug in negative type narrowing for class patterns in match statements when the class in the class pattern is one of the designated "special built-in classes" specified in PEP 634 and a class argument is specified.

Bug Fix: Fixed a bug that resulted in incorrect TypeVar resolution when the TypeVar was used in a Type[T] type expression, was constrained, and two of the constraints overlapped in type.

Bug Fix: Fixed an edge case in the code flow engine that theoretically could result in incorrect type evaluation.

Bug Fix: Fixed a bug in the code flow engine that resulted in inconsistent type evaluation depending on order of evaluation in some cases where a variable is modified in a loop.

Bug Fix: Fixed bug that resulted in a stack overflow when evaluating unions with large numbers of subtypes.

Published 1.1.223

Bug Fix: Fixed a bug in negative type narrowing logic for value patterns in match statement.

Behavior Change: Removed provisional support for PEP 677 (Alternate Call Syntax) because the proposal was rejected by the Python steering council.

Bug Fix: Fixed a bug that led to incorrect type evaluation in the "implied else" code flow path.

Bug Fix: Improved support for functions or methods that return a context manager that swallow exceptions, such as pytest.raises.

Behavior Change: Modified reportIncompatibleVariableOverride check to permit a ClassVar in the base class to be overridden by a compatible class declaration in a child class.

Bug Fix: Fixed a bug in the type evaluator that led to false positives when assigning a function type to another function type and the source contained parameters annotated with literal types and the dest contained corresponding parameters annotated with TypeVars.

Bug Fix: Fixed bug in the handling of wildcard imports. If the target module doesn't contain a dunder all definition, the resulting imported symbol list should exclude names that start with a single underscore.

Bug Fix: Fixed bug that resulted in a false positive error when using a TypeVarTuple in a classmethod.

Behavior Change: Changed heap overflow detection to use a dynamic value based on available memory rather than a hard-coded size. For the pyright VS Code extension, changed the default "max heap size" from 1.7GB to 3.0GB on 32-bit systems. On 64-bit systems, this value appears to already be a higher value (4GB), and it doesn't appear to get overridden by the lower number.

Published 1.1.222

Bug Fix: Fixed bug that resulted in false positive when using a recursive type alias with a generic dataclass constructor.

Bug Fix: Fixed a bug that results in a false negative when handling a function parameter that is annotated with a function-scoped TypeVar and has a default argument value.

Behavior Change: Changed the handling of reveal_type so it participates in bidirectional type inference when used within a larger expression.

Bug Fix: Fixed long-standing bug in logic that applies config file settings for diagnostic rule severity levels. The bug caused all settings overrides to be ignored if a pyrightconfig.json file was present. The new logic applies the default values, then the settings overrides, then the pyrightconfig.json file values. The change also simplifies the code, which was getting a bit unmaintainable.

Enhancement: Extended dataclass_transform to support transform_descriptor_types parameter.

Enhancement: Added support for an unpacked TypedDict as a type annotation for a *kwargs parameter.

Bug Fix: Improved the type(x) is y type narrowing logic to handle the case where y is a TypeVar or Self type.

Bug Fix: Fixed bug in match statement type narrowing. It wasn't properly handling the negative type narrowing case for class patterns when the subject expression was a bound TypeVar or Self type.

Bug Fix: Fixed a bug related to the __eq__ method (and other order methods) that are synthesized for a dataclass. The parameter name was incorrect. It should be other.

Bug Fix: Added support for NFKC normalization of identifiers as specified in the Python lexical specification.

Published 1.1.218

Enhancement: Allow "--watch" to be used in conjunction with "--outputjson" command-line options.

Enhancement: Added support for bidirectional type inference for yield statements. The expected type is based on the first type argument in a Generator or AsyncGenerator return type annotation.

Enhancement: Added the ability to add new symbols to builtins by simply adding a type stub file named __builtins__.pyi locally.

Bug Fix: Fixed a bug that led to a false positive error when handling bidirectional type inference for tuple expressions when the expected type was a union that contained multiple tuple subtypes.

Bug Fix: Fixed a bug that resulted in a false negative when a list comprehension was used within a class body and referenced a class-scoped variable in a subexpression other than the first iterable. This also fixes a similar bug where a lambda was used within a class body and referenced a class-scoped variable in its return expression. These now property generate errors, reflecting the runtime behavior.

Bug Fix: Fixed a bug that resulted in incorrect type inference for positional parameters used in class patterns if the corresponding class was defined in a "py.typed" library and it defined a __match_args__ symbol with no annotation.

Bug Fix: Fixed bug in stub generator that caused it to omit import statements with multi-part names (e.g. import a.b.c) even though there was a reference within the generated stub to the imported module.

Enhancement: Extended type narrowing for class pattern matching so it supports narrowing in the negative case when arguments are present and when the pattern class is generic.

Bug Fix: Fixed a bug that resulted in a false negative when a *args parameter was used in conjunction with a * keyword-only separator parameter. This generates a syntax error at runtime.

Bug Fix: Fixed a false positive error when TypeGuard was used without a type argument in a runtime manner (outside of a type annotation).

Bug Fix: Fixed recent regression that results in false positive errors detected in the reportUnknownParameterType diagnostic check when the function includes a parameter with a double underscore name indicating that it's positional-only.

Enhancement: Improved signature help and hover text for synthesized __init__ dataclass method when a parameter uses a field descriptor with a default value.

Published 1.1.217

Bug Fix: Fixed a bug that resulted in a false positive error when passing an *args argument typed as an unpacked TypeVarTuple to a function that includes an unpacked TypeVarTuple parameter.

Enhancement: Added special-case bidirectional type inference for the right operand of the "|" and "|=" operators (with an expected type based on the left operand). This supports the case where the left operand is a TypedDict and the right operand is a dict expression that conforms to the TypedDict type.

Bug Fix: Fixed a bug in the reportIncompatibleMethodOverride check that resulted in false positive errors when both the base class and child methods have overloads but the base class does not have an implementation and the child class does.

Enhancement: Updated typeshed stubs to the latest version.

Bug Fix: Fixed a bug that results in false positive errors when a ClassVar type declaration appears within an Annotated.

Bug Fix: Added special-case handling of Generic base types to match the (undocumented) runtime behavior. Without this special-case handling, pyright reports that "a consistent method ordering cannot be found" in some cases where the runtime does not.

Bug Fix: Fixed bug that is leading to some crashes that appear in the telemetry.

Bug Fix: Added recursion detection for wildcard import lookups during code flow.

Bug Fix: Fixed a bug that caused a type alias of Any to be evaluated as Unknown if defined within a py.typed library.

Performance: Improved performance when analyzing types that involve some forms of recursive type aliases.

Enhancement: Added support for typing_extensions.Never and typing.Never type and unified the underlying handling of Never and NoReturn, which are synonyms.

Enhancement: Improved type stub generation code to emit definitions for TypeVar, TypeVarTuple, ParamSpec and NewType.

Sourced from coverage's changelog.

Version 6.3 — 2022-01-25

• Feature: Added the lcov command to generate reports in LCOV format. Thanks, Bradley Burns <pull 1289_>. Closes issues 587 <issue 587_> and 626 <issue 626_>_.

• Feature: the coverage data file can now be specified on the command line with the --data-file option in any command that reads or writes data. This is in addition to the existing COVERAGE_FILE environment variable. Closes issue 624. Thanks, Nikita Bloshchanevich <pull 1304_>.

• Feature: coverage measurement data will now be written when a SIGTERM signal is received by the process. This includes :meth:Process.terminate <python:multiprocessing.Process.terminate>, and other ways to terminate a process. Currently this is only on Linux and Mac; Windows is not supported. Fixes issue 1307_.

• Dropped support for Python 3.6, which reached end-of-life on 2021-12-23.

• Updated Python 3.11 support to 3.11.0a4, fixing issue 1294_.

• Fix: the coverage data file is now created in a more robust way, to avoid problems when multiple processes are trying to write data at once. Fixes issues 1303 <issue 1303_>_ and 883 <issue 883_>_.

• Fix: a .gitignore file will only be written into the HTML report output directory if the directory is empty. This should prevent certain unfortunate accidents of writing the file where it is not wanted.

• Releases now have MacOS arm64 wheels for Apple Silicon, fixing issue 1288_.

Published 1.1.216

Bug Fix: Fixed recent regression that resulted in a crash (stack overflow) in the code flow engine.

Bug Fix: Fixed a bug that resulted in unknown types in member access expressions to go unreported with reportUnknownMemberType was enabled. This occurred when the member access expression was located within a subscript of an index expression.

Performance: Changed the logic that infers a NoReturn type to avoid inferring symbol types. This was causing a bunch of extra work to be performed in complex unannotated code bases like sklearn.

Performance: Fixed performance issue in parser for deeply-nested parenthesized expressions.

Bug Fix: Fixed bug in callable type compatibility logic. It was not properly handling some edge cases where a keyword parameter in the source and destination had an incompatible type if one or both of the types were specialized.

Bug Fix: Fixed a bug that resulted in false positives when specializing a callback protocol with a TypeVarTuple when the callback protocol also contained one or more keyword parameters that were generic.

Bug Fix: Fixed a bug in the protocol invariance checking logic. It wasn't properly handling protocols that used a TypeVarTuple as a type parameter that wasn't last (right-most) in the type parameter list.

Behavior Change: Changed import resolution order to more closely match PEP 561. Typeshed stdlib type stubs are now resolved later in the import resolution process, after all local modules and modules within the python environment.

Published 1.1.215

Bug Fix: Fixed bug that resulted in crash when extremely large integer literals are encountered.

Bug Fix: Fixed bug that caused "extraPaths" specified for individual execution environment to be combined for all execution environments if a default "extraPaths" was also specified in the same config file.

Bug Fix: Fixed handling of NoReturn type, which should act like Never in that both are considered "bottom types" and are assignable to any other type.

Enhancement: Updated typeshed stubs to the latest.

Enhancement: Added new diagnostic check "reportMatchNotExhaustive" which reports cases where a match statement doesn't exhaustively cover all cases.

Enhancement: Added support for unpack operator for tuples used within type arguments. Support for this new syntax will appear in Python 3.11.

Bug Fix: Added code in parser to detect obscenely deep parse subtrees containing binary and unary operations. These were sometimes leading to crashes in the binder and type evaluator. The parser now replaces them with error parse nodes and reports an error to the user.

Bug Fix: Added recursion check in type guard logic to address stack overflow issue seen in telemetry.

Bug Fix: Fixed bug that produces a false positive when attempting to assign a value of type Type[NoneType] to Type[None]. These are equivalent, so the assignment should be allowed.

Enhancement: Enhanced parser to detect and report a runtime error that occurs when using a generator expression without surrounding parens as an argument within a call expression when more than one argument or a trailing comma is present.

Bug Fix: Fixed a bug that resulted in a false positive when a member access expression targeted an attribute that was returned by a __getattr__ method that returns a descriptor object. The old logic was binding the descriptor to the object, but that's inconsistent with the way things work at runtime.

Enhancement: Improved analysis of finally block and the code that comes after the finally block so type narrowing performed within the finally block in the fall-through case is preserved.

Enhancement: Added support for Final and ClassVar annotations embedded within Annotated. Runtime support has recently been added for this case.

Enhancement: Added support for InitVar that is wrapped in Annotated. Support is being added for this in the runtime.

Enhancement: Added special-case handling for methods declared as returning a Generator, AsyncGenerator or AwaitableGenerator that do not contain a yield statement. This special case applies only to methods declared in stub files, an abstract method, or a protocol definition with no code.

Bug Fix: Improved support for custom subclasses of the builtin property class. Previously, the special-case handling in place for property were not handling these custom subclasses well, and this resulted in several false positive errors and incorrect type evaluations.

Published 1.1.188

Bug Fix: Fixed issue that caused import resolution failures for certain submodules of google.cloud.

Bug Fix: Fixed crash in completion provider.

Bug Fix: Fixed bug in ParamSpec type evaluation that caused a false positive error when assigning a callable with a Concatenate to another ParamSpec.

Bug Fix: Fixed bug in ParamSpec logic that resulted in false positive when a TypeVar was used as within a Concatenate expression.

Bug Fix: Fixed bug in type evaluator that resulted in false positive error in strict mode. Type of call argument expression was incorrectly reported as partially unknown in some cases.

Bug Fix: Fixed bug that resulted in a false positive when a tuple with known element types is used as an unpacked argument in a call to a function that uses position-only parameters.

Bug Fix: Fixed type checking hole (false negative) in certain circumstances involving loop constructs and variables whose types are modified within these loops. This bug fix also has a positive performance impact when analyzing functions with complex code flow graphs.

Bug Fix: Fixed issue that caused CLI version of pyright to use incorrect Python interpreter to discover the Python version when no "pythonVersion" configuration setting was supplied.

Enhancement: Implemented diagnostic check for a ClassVar declaration that uses a type variable. PEP 526 explicitly states that this is not allowed.
