* Phpstan Baseline Fixes 2022-09-21
Eliminate about 200 more lines from Phpstan baseline. For Helper/Sample and Helper/Html and others, many properties are declared as protected despite the fact that the classes do not extend any other class, and there are no classes which extend them. They are changed to private; this could be a breaking change in circumstances for which I cannot think of a use case (user extends class for some reason).
* Slightly Botched Merge Commit
Hope this fixes phpstan.
Shared/Font is hardly covered in unit tests (as opposed to Style/Font which is completely covered). And it presented some good opportunities for code optimization. I wrote and tested the new unit tests first, then optimized the code and confirmed that everything still works.
There is still a bit of a gap with "exact" measurements. I had tests ready, but had to withdraw them when I discovered they weren't quite portable (see https://github.com/php/php-src/issues/9073).
PHP 8.2 is supposed to deprecate the use of `['self', 'functionname']` for callables, suggesting the use of `[self::class, 'functionname']` instead. We made this change in a recent PR, and, while I'm thinking about it, I'll fix the remaining 2 modules with this construction. Vlookup is already adequately covered in unit tests. Reader/Xls/MD5 is not; a unit test is added.
See issue #2239. Problem is dealt with at the source, by making sure that Reader Xls checks for use of 'GENERAL' rather than 'General'. There doesn't seem to be a reason to test in other places, or to test for other casing variants.
* Tweaks to Input File Validation
This started as a response to issue #1718, for which it is a partial (not complete) solution. The following changes are made:
- canRead can currently throw an exception. This seems wrong. It should just return true/false.
- Breaking change of sorts. When AssertFile encounters a non-existent or unreadable file, it throws InvalidArgumentException. This does not make sense. I have changed it to throw PhpSpreadsheet/Reader/Exception.
- Since the previous bullet item required changing of most of the Reader files anyhow, this is a good time to add explicit typing for canRead in the function signature rather than the DocBlock. Since all the canRead functions inherit from an abstract version in IReader, they all have to be changed simulatneously. Except for Xlsx and Ods, most of the Reader files are otherwise unchanged.
- AssertFile is changed to add an optional "zip member" parameter. It will check for the existence of an appropriate member in what is supposed to be a zip file. It is used by Xlsx and Ods.
- Verifying that a given file is a valid zip ought to be a feature of ZipArchive. Thanks to a particularly nasty bug in php/libzip (see https://bugs.php.net/bug.php?id=81222), it is unsafe to attempt to open a zero-length file as a zip archive. There is a solution, but it does not apply to all the PHP releases which we support, and isn't even necessarily supported on all the point versions of the PHP versions which we do support. I have coded up a manual test for "valid zip", with a comment pointing to the spec.
- In theory, tests now cover 100% of the code in Shared/File. In practice ... One of the tests require that chmod works properly, which is not quite true on Windows systems, so that test is skipped on Windows. Another test requires that php.ini uses a non-default value for upload_temp_dir (can't be overridden in application code), which is probably not the case when Github runs the unit tests, so that test is skipped when appropriate. I have run tests for both on systems where they are not skipped.
* Update File.php
* Scrutinizer Timeout
It's not actually timing out, it's just waiting for something to finish that finished ages ago. Making a meaningless comment change in hopes that will clear the jam. Not particularly hopeful.
* Xls Reader Handle MACCENTRALEUROPE With or Without Hyphen
Fixes issue #549 and https://github.com/Maatwebsite/Laravel-Excel/issues/989 (which is the source of the new test file). Some systems accept MACCENTRALEUROPE as the name for the appropriate encoding, and some accept MAC-CENTRALEUROPE. I fortunately have access to at least one of each type, and have run the tests on each.
CodePage.php has an array of translations from codepage number to string. I now allow the value to itself be an array; if so, the code will test each in turn to see if it can be used in iconv. I did not go fishing for other similar problems. If such show up, they can be dealt with in the same manner as this one. I don't really expect others, since this is a problem not merely for Xls, but, even then, it applies only to BIFF5 and earlier.
I also moved XlsTest from Reader to Reader/Xls.
* Cache Successful Result For Future Use
Per suggestion from @MarkBaker
* Fix for the BIFF-8 Xls colour mappings in the Reader
* Unit test for reading colours, writing hen rereading and ensuring that the RGB values have not changed
