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.
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+.
Fix for issue #1897.
The existing hashing code seems to work correctly almost all the time, but there are exceptions. It is replaced by an exact implementation of the spec, including a link to the spec in the comments. Cases known to fail are added to the unit test suite.
The spec expects the string to be at most 255 bytes (yes, bytes not characters). The program had permitted any length; it will now throw an exception when the maximum length is exceeded.
Xls does not support any hashing algorithm except basic. The Xls writer had, nevertheless, accepted the results of any of the other possible algorithms. This leads to (a) a worksheet that can't be unprotected, and (b) deprecation notices during the write (because it is using hexdec, which expects only hex characters, and the other algorithms generate non-hex characters). I have changed Xls writer to ignore passwords generated by other algorithms. An alternative would be to have the password hasher generate both an algorithmic password (for use by Xlsx) and a basic password (for use by Xls); I think that is too complex a solution, but can look into it if you think it worthwhile.
I do not see any current support for Worksheet passwords in ODS Reader or Writer. I did not add support in this PR.
I added a new test to confirm the password for reading a spreadsheet is consistent with the one used for writing it. As you can see from the comments for the new test, it had an unusual problem with a somewhat unusual solution.
