* Implement NonInvariantChildProperty detection
See https://github.com/vimeo/psalm/issues/4184
* Delete test cases with 'parentSetsWiderTypeInConstructor'
As I understand it these are not valid test cases. They
emit NonInvariantPropertyType issues which seems correct - the property
type variation is I think a latent bug in the sample code.
* Reduce shortcode for NonInvariantPropertyType to 1+max used shortcode on master
* Track references on global variables
Add global type references to the type map, and fix up unused detection on global variables.
* Add null assertions
* PHPCS
* Add constant fetch to reference map
To support showing constant types on hover of constant references, we need to add them to the ref map.
* Fix root constants
* PHPCBF
* Add completions for known array keys
* Use dynamic gap value
* Provide completions for known type contexts
* Fix formatting
* Remove trailing comma
* PHPCS fixes
* Remove support for literal floats
* Fix test for floats
* Remove ReflectionType::getName(), move ReflectionType::isBuiltin()
* `ReflectionType::getName()` was never there: https://3v4l.org/1iZt4
* `ReflectionType::isBuiltin()` was moved to
`ReflectionNamedType::isBuiltin()` in PHP 8
Fixesvimeo/psalm#5089
* Fix test
* Mark test as php 8.0 only
* Use separate exit code to indicate Psalm finding issues
This will allow to distinguish successful run that found some issues
from crashes.
* Fix e2e test expectations
* Documented exit statuses
* Support compleitions on class references
This provides completions on class references (as opposed to initiated objects via the type map), so you can do `MyClass::` and get completitions for static methods and constants etc.
* Only provide completions for references that don't exist
* Remove file map cache when re-analyzing files
When the project is re-analyzed under the single thread condition (not using a process pool), the filemaps are not cleared before re-analyzing files. This means that file maps only get appended to. If you delete the contents of a file via the LSP, the file map will still be populated with all the old values for example.
In doing this I had to write a few more tests to check my assumptions too, so adding those additional tests.
* Rename test
* Formatting
* Formatting again!
* #4997 added more precise stub for `count()` returning `0` or `positive-int` on known types
* #4997 updated `count()` to support `\SimpleXmlElement` and `\ResourceBundle` counting, as well as handling hardcoded 2-element-arrays cases
This patch:
* adds support for `count(\SimpleXmlElement)` (https://www.php.net/manual/en/simplexmlelement.count.php)
* adds support for `count(\ResourceBundle)` (https://www.php.net/manual/en/resourcebundle.count.php)
* removes usage of global constants from stub (not supported - see https://www.php.net/manual/en/function.count.php)
* adds support for identifying fixed-element-count arrays, for example `count(callable&array)`, which is always `2`
* #4997 adapted `FunctionCallReturnTypeFetcher` to infer `TPositiveInt` for `count(TNonEmptyArray)` and `count(TNonEmptyList)`
* The `FunctionCallReturnTypeFetcher` is responsible for defining the precise type of a `\count(T)`
expression when given a `T`, so we baked the whole type resolution for `positive-int`, `0` and
`positive-int|0` directly in there.
While this complicates things, it is also true that it is not possible right now (for the stubs)
to provide the level of detail around `count()` that is required by the type inference system
for such a complex function with so many different semantics.
* Split unit test over multiple jobs in GitHub Actions, lowering the total run time
* rename FileManipulationTest to FileManipulationTestCase so it does not run as a standalone Test
* add stubs for standard iterators
* Apply suggestions from code review cc @weirdan
