I initially added these as part of my TryAnalyzer rewrite to allow testing complicated `finally` types like this:
```
$foo = 1;
try {
$foo = 2;
} catch (Exception $_) {
$foo = 3;
} finally {
$bar = $foo;
/** @psalm-check-type-exact $bar = 1|2|3 */;
}
/** @psalm-check-type-exact $bar = 2|3 */;
```
Using the `'assertions'` in tests doesn't work since the type is different inside the `finally`.
I decided to extract the new annotation from the rest of my changes and do a separate pull request since I think others may find it useful, and it should be much easier to review than the entire TryAnalyzer rewrite.
Add InvalidClassConstType issue as alternative to LessSpecificClassConstType when type isn't contravariant.
Handle final class consts (#6395).
Use double quotes for types in class const issues.
As counterpart to existing `AfterStatementAnalysisEvent` - invoked in
`\Psalm\Internal\Analyzer\StatementsAnalyzer` - this changed introcued
a corresponding `BeforeStatementAnalysisEvent`.
Resolves: #7534
This change introduces new `BeforeAddIssueEvent` which is invoked
from `IssueBuffer::add`, which allows to collect and intercept code
issue in a generic way.
Resolves: #7528
ProjectAnalyzer consumed Config::$fileExtensions early in its
constructor - without having processed plugins' modifications,
registering their custom scanners or analyzer implementations.
This change
* adds new specific interface \Psalm\Plugin\FileExtensionsInterface
to be used by plugin implementations
* extracts file extension handling from \Psalm\PluginRegistrationSocket
and interface \Psalm\Plugin\RegistrationInterface to a new dedicated
\Psalm\PluginFileExtensionsSocket and new interface
\Psalm\Plugin\FileExtensionsInterface
!!! this is a breaking change in PluginRegistrationSocket !!!
* adds runtime in-memory cache for Config::$plugins
* calls new method Config::processPluginFileExtensions(), providing
modifications to file extension only early in ProjectAnalyzer
* adjusts documentation
Add class const covariance support (fixes#5589).
Add check for overriding const from interface in PHP < 8.1 (fixes#7108).
Add check for ambiguous const inheritance.
