This PR will be merged at the end of this month. As the README says, we maintain support for Php Versions for six months beyond their end of life. That time has now arrived for 8.1.
Fix#4092. Change default value for Csv Reader autodetect line endings. Prior behavior can be enabled via `setTestAutodetect(true)`.
Change default value for Html Writer "better boolean" logic. Prior behavior can be explicitly enabled via `setBetterBoolean(false)`.
Change default for Xlsx Writer forceFullCalc option. Prior behavior can be explicitly enabled via `setForceFullCalc(null)`.
This has been requested a few times, most recently issue #4092. Because it's a breaking change, I haven't proceeded with it. But, because I have a breaking change PR #4240 already in the queue, this gives a plan for getting where we want to go (under the extremely likely assumption that most users don't deal with Csv files with Mac line endings). This PR doesn't change the current behavior, but it gets us to a state where a single-line change will be sufficient when the time comes for a new major release.
With PhpUnit 10 came the ability to use Php attributes rather than doc-block annotations for things like "data provider". PhpUnit 11 deprecates the use of annotations, and PhpUnit 12 will not not permit their use. Since PhpUnit 11 requires Php8.2+, we cannot adopt it as long as we support Php8.1, which will continue to be the case for some time. However, there is no penalty for early adoption.
Php-cs-fixer can use:
```
'php_unit_attributes' => ['keep_annotations' => false],
```
This allows us to run `composer fix` to automate all the needed changes. No manual changes were needed for any of the test members.
With this change, PhpUnit 9 can no longer be used with the test suite. File composer.json is updated to reflect that reality, and phpunit9.xml.dist, which has been supplied in case anyone needed to use PhpUnit 9, is no longer required, and is thus deleted. For now, PhpUnit 11 is not being added as a possibility.
No source code is changed in this PR.
See #4161. The best way to future-proof is to set the escape character to null string, and set testAutoDetect to false before reading. However, depending on the file being read, this may lead to different results than expected. This will be unavoidable because Php itself will change. This PR adds a new static method `affectedByPhp9` to Csv Reader. This can be used to identify in advance whether an input file will be affected by the changes. This will allow users to identify problems in advance, and prepare for how they might be handled.
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+.
With the deprecation of `auto_detect_line_endings` in Php8.1, there have been some tickets (issue #2609 and PR #2438). Although the deprecation message is suppressed, users with a homegrown error handler may still see it. I am not very concerned about that symptom, but I imagine that there will be more similar tickets in future. This PR adds a new property/method to Reader/CSV to allow the user to avoid the deprecated code, at the negligible cost of being unable to read a CSV with Mac line endings even on a Php version that could support it.
* Csv Handling of Booleans (and an 8.1 Deprecation)
PhpSpreadsheet writes boolean values to a Csv as null-string/1, and treats input values of 'true' and 'false' as if they were strings. On the other hand, Excel writes boolean values to a Csv as TRUE/FALSE, and case-insensitively treats a matching string as boolean on read. This PR changes PhpSpreadsheet to match Excel.
A side-effect of this change is that it fixes behavior incorrectly reported as a bug in PR #2048. That issue was closed, correctly, as user error. The user had altered Csv Writer, including adding ```declare(strict_types=1);```; that declaration was the cause of the error. The "offending" statements, calls to strpbrk and str_replace, will now work correctly whether or not strict_types is in use.
And, just as I was getting ready to push this, the dailies for PHP 8.1 introduced a change deprecating auto_detect_line_endings. Csv Reader uses that setting; it allows it to process a Csv with Mac line endings, which happens to be something that Excel can do. As they say in https://wiki.php.net/rfc/deprecations_php_8_1, where the proposal passed without a single dissenting vote, "These newlines were used by “Classic” Mac OS, a system which has been discontinued in 2001, nearly two decades ago. Interoperability with such systems is no longer relevant." I tend to agree, but I don't know that we're ready to pull the plug yet. I don't see an easy way to emulate that functionality. For now, I have silenced the deprecation notices with at signs. I have also added a test case which will fail when support for that setting is pulled; this will give time to consider alternatives.
* Scrutinizer: Handling ini_set
This could be interesting. It doesn't like not handling an error condition for ini_set. Let's see if this satisfies it.
