phan v3.2.1 Release Notes

Release Date: 2020-09-13 // over 3 years ago

  • 🆕 New features (Analysis):

    • Don't compare parameter types against alternate method signatures which have too many required parameters.
      (e.g. warn about max([]) but not max([], [1]))
    • Support /** @unused-param $param_name */ in doc comments as an additional way to support suppressing warnings about individual parameters being unused.
    • Warn about loop conditions that potentially don't change due to the body of the loop.
      This check uses heuristics and is prone to false positives.
      🆕 New issue types: PhanPossiblyInfiniteLoop
    • Treat unset($x); as shadowing variable definitions during dead code detection.
    • 🔄 Change the way $i++, --$i, etc. are analyzed during dead code detection
    • Properly enable allow_method_param_type_widening by default when the inferred minimum_target_php_version is '7.2' or newer. (#4168)
    • 🚀 Start preparing for switching to AST version 80 in an upcoming Phan 4 release. (#4167)`

    🐛 Bug fixes:

    • 🛠 Fix various crashes in edge cases.
    • 🛠 Fix crash with adjacent named labels for gotos in the polyfill/fallback parser.
    • 🛠 Fix false positive unused parameter warning with php 8.0 constructor property promotion.

    🔌 Plugins:

    • 🔌 Warn about # comments in PHPDocInWrongCommentPlugin if they're not used for the expected #[ syntax of php 8.0 attributes.

    🚧 Maintenance:

    • ⚡️ Update polyfill/fallback parser to properly skip attributes in php 8.0.
      🚀 The upcoming Phan 4 release will support analyzing attributes, which requires AST version 80.
