[dependabot-preview]

Bumps phan/phan from 2.4.8 to 4.0.7.

Changelog

Sourced from phan/phan's changelog.

Jun 26 2021, Phan 4.0.7

Language Server/Daemon mode:

• Fix an uncaught exception sometimes seen checking for issue suppressions when pcntl is unavailable.

Maintenance:

• Expand allowed netresearch/jsonmapper version ranges to include ^4.0 for php 8.1 support.
• Update dependencies in composer.lock for compatibility with php 8.1 in published phar files.

Bug fixes:

• Don't emit PhanCompatibleNonCapturingCatch when minimum_target_php_version is '8.0' or newer. (#4433)

• Stop ignoring @return null and @param null $paramName in phpdoc. (#4453)

  Stop special casing @param null now that Phan allows many other literal types in param types.

May 19 2021, Phan 4.0.6

New Features (Analysis):

• Partially support php 8.1 enums (#4313) (infer the real type is the class type, that they cannot be instantiated, that enum values cannot be reused, and that class constants will exist for enum cases)

  New issue types: PhanReusedEnumCaseValue, PhanTypeInstantiateEnum, PhanTypeInvalidEnumCaseType, PhanSyntaxInconsistentEnum, PhanInstanceMethodWithNoEnumCases, PhanInstanceMethodWithNoEnumCases, PhanEnumCannotHaveProperties, PhanUnreferencedEnumCase, PhanEnumForbiddenMagicMethod.

• Support php 7.4 covariant return types and contravariant parameter types when the configured or inferred minimum_target_php_version is '7.4' or newer (#3795)

• Add initial support for the php 8.1 never type (in real return types and phpdoc). (#4380) Also add support for the phpdoc aliases no-return, never-return, and never-returns

• Support casting iterable<K, V> to Traversable<K, V> with is_object or !is_array checks

• Detect more types of expressions that never return when inferring types (e.g. when analyzing ?:, ?? operators)

• Use php 8.1's tentative return types from reflection (hasTentativeReturnType, getTentativeReturnType) to assume real return types of internal functions/methods (#4400)

  This can be disabled by setting use_tentative_return_type to false (e.g. when using subclasses of internal classes that return incompatible types).

• Warn about modifying properties of classes that are immutable at runtime (enums, internal classes such as \Closure and \WeakRef, etc.) (#4313) New issue type: PhanTypeModifyImmutableObjectProperty

Dead code detection:

• Infer that functions with a return type of never (or phpdoc aliases such as no-return) are unreachable when performing control flow analysis. This can be disabled by setting dead_code_detection_treat_never_type_as_unreachable to false

  Note that control flow is only affected when UseReturnValuePlugin is enabled.

Plugins:

• In UseReturnValuePlugin, also start warning about when using the result of an expression that evaluates to never New issue types: PhanUseReturnValueOfNever

Bug fixes:

• As part of the work on php 7.4 contravariant parameter types, don't automatically inherit inferred parameter types from ancestor classlikes when (1) there is no @param tag with a type for the parameter on the overriding method and (2) the ancestor parameter types are a subtype of the real parameter types unless
