phan/phan 2.7.0

Release 2.7.0 supporting PHP 7.0-7.4 syntax

on PHP Packagist

New features(CLI, Configs):

• Sort output of --dump-ctags=basic by element type before sorting by file name (#3811)
  (e.g. make class and global function declarations the first tag type for a tag name)
• Colorize the output of phan_client by default for the default and text output modes. (#3808)
  Add phan --no-color option to disable colors.
• Warn about invalid CLI flags in phan_client (#3776)
• Support representing more AST node types in issue messages. (#3783)
• Make some issue messages easier to read (#3745, #3636)
• Allow using --minimum-severity=critical instead of --minimum-severity=10 (#3715)
• Use better placeholders for parameter default types than null in issue messages and hover text (#3736)
• Release phantasm, a prototype tool for assembling information about a codebase and aggressively optimizing it.
  Currently, the only feature is replacing class constants with their values, when safe to do so.
  More features (e.g. inlining methods, aggressively optimizing out getters/setters, etc.) are planned for the future.
  See tool/phantasm --help for usage.

New features(Analysis):

• Improve analysis of php 7.4 typed properties.
  Support extracting their real union types from Reflection information.
  Infer the existence of properties that are not in ReflectionClass->getPropertyDefaults()
  due to being uninitialized by default.
• Emit PhanAbstractStaticMethodCall* when calling an abstract static method statically. (#3799)
• Emit PhanUndeclaredClassReference instead of PhanUndeclaredClassConstant for MissingClass::class.

Language Server/Daemon mode:

• Catch exception seen when printing debug info about not being able to parse a file.
• Warn when Phan's language server dependencies were installed for php 7.2+
  but the language server gets run in php 7.1. (phpdocumentor/reflection-docblock 5.0 requires php 7.2)
• Immediately return cached hover text when the client repeats an identical hover request. (#3252)

Miscellaneous:

• PHP 8.0-dev compatibility fixes, analysis for some new functions of PHP 8.0-dev.
• Add symfony/polyfill-php72 dependency so that symfony 5 will work better in php 7.1.
  The next Phan major release will drop support for php 7.1.
