* Eliminate Some Phpstan Annotations
Some changes are possible due to Php8+ features like null-safe operators and Stringable.
* Possible Uninitialized Variable
Scrutinizer might be technically correct.
* CellAddress Static -> Self
I don't understand the use case for extending it, which would be the reason for using static rather than self.
* Update Worksheet.php
While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
And quite a bit more manual changes. The idea is that typing of our
tests can be a bit more loose, so we assume PHPDoc is mostly correct. If
that happens to be wrong, it should be caught by the tests themselves.
Successor to PR #3523. There are 494 single-line changes (`public function provider` to `public static function provider`) in this PR. None of these were made manually; they were all created with the following script (adapted from
https://stackoverflow.com/questions/25909820/how-to-recursively-iterate-through-files-in-php):
```php
$dir = 'C:/git/unit10prep2/tests/PhpSpreadsheetTests';
$it = new RecursiveDirectoryIterator($dir);
// Loop through files
foreach(new RecursiveIteratorIterator($it) as $file) {
if ($file->getExtension() === 'php') {
$contents = file_get_contents($file);
$new = preg_replace('/public function (\\w*)([Pp])rovider/', 'public static function $1$2rovider', $contents);
if ($new !== $contents) {
echo "changing $file\n";
file_put_contents($file, $new);
}
}
}
```
After this PR, there will be one more, with a small number of test changes, and enabling PhpUnit 10 for Php 8.1+.
* Update Some Doc Block Annotations
See PR #2010. That PR was never completed, and has gone stale. However, it was correct in identifying a situation where the doc block was not entirely accurate. It did not go far enough - several closely-related methods have similar problems. This PR attempts to fix the original problem and its close relations. Aside from the doc block changes, there are very minor changes to executable code. It also changes some of the unit tests targeted at the methods in question to eliminate mocking in favor of 'real' tests.
* Change Method to Static
Otherwise Scrutinizer will complain, even though Phpstan doesn't.
* Scrutinizer
Various clean-up activities.
* Scrutinizer
@#&$(*#&$ Got complexity down from 53 to (I think) 50. Don't really know what the target is.
* Code Changes Suggested By Review
Some improvements suggested in review by @PowerKiKi.
* Update Cells.php
* Merge Conflict
A change to a parameter name caused several problems when trying to fix it on Github. Fixing it locally should do the trick.
* Merge Conflicts in Phpstan Baseline
PR #2382 made a large number of changes to Phpstan Baseline, some of which conflicted with the Phpstan Baseline changes in this PR. This should resolve them all.
