Because they tend to clutter our code a lot and unfortunately, there are
lots of false positives. Instead, it would probably be better to deal
with false positives out of band, via the Scrutinizer web UI.
* ListWorksheetInfo/Names for Html/Csv/Slk
Fix#3706. ListWorksheetInfo is implemented for all Readers except Html. For most (not all), ListWorksheetInfo is more efficient than reading the spreadsheet. I can't think of a way to make that so for Html, but that shouldn't be a reason to leave it unimplemented.
ListWorksheetNames is not implemented for Html, Csv, or Slk. It isn't terribly useful for those formats, but that isn't a reason to omit it. The requester's use case consists of using IOFactory to create a reader for a file of unknown format and determining the first sheet name. That seems legitimate, but it is currently not possible without extra user code if the file is Html, Csv, or Slk; this PR will make it possible.
When Excel opens a Slk or Csv file, the sheet name is based on the file name. PhpSpreadsheet does this for Slk, but it uses a default name for Csv. I am not interested in creating a break for that behavior, but I have added a new boolean property `sheetNameIsFileName` with a setter to Csv Reader. The requester actually mentioned that possibility in our discussion, although it is not essential to the request.
As an adjunct to the issue, the requester wishes to use the worksheet name in `setLoadSheetsOnly`. That is already possible for Html, Csv, and Slk, but that particular property is ignored for those formats. I do not see a reason to change that behavior. This treatment is now explicitly noted in the documentation for property `loadSheetsOnly`.
There had been no tests for what happens when `loadSheetsOnly` is specified but no sheets match the criteria for the formats for which this makes sense (Xlsx, Xls, Ods, Gnumeric, Xml). The behavior was not consistent - some formats threw an Exception while others continued with a single empty worksheet. All cases attempt to set the active sheet, and they will now all throw identical Exceptions when they attempt to do so in this situation. Tests are added for each.
There also had been no tests for `loadSheetsOnly` returning more than one sheet. One is added.
* Update LoadSheetsOnlyTest.php
Add strict types to this new test, consistent with work being done in PR #3718.
* Update LoadSheetsOnlyTest.php
Add strict types to this new test, consistent with work being done in PR #3718.
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.
* Read Code Page for Xls ListWorksheetInfo/Names for BIFF5
Fix#3671. Xls reader was not processing Code Page as part of functions ListWorksheetInfo/Names, which was causing them to fail for for BIFF5 (and BIFF7); this was not a problem for BIFF8. There were no unit tests for these functions for either BIFF5 or BIFF8. There are now.
* Add getVersion and getCodePage Methods
These came about because test file for non-standard codepage was supposed to be BIFF5, but turned out to be BIFF8 using UTF-16 with some string data otherwise encoded. Add a BIFF5 equivalent (some hex editing was required), and the means to distinguish one from the other.
* Found MACCENTRALEUROPE Text in BIFF8
It was used for 'Last Modified By' property, even though bulk of spreadsheet uses UTF-16LE. Add a test.
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+.
The code currently allocates the style object as a non-conditional style, leading to corruption when the spreadsheet is written out.
That being said, Font Color is the only Conditional Formatting I have gotten to work for Xls for read or write. Use of other styles will essentially continue to be ignored, but will at least no longer result in corrupt spreadsheets.
Fix#3369. The parser had failed to account for `TRUE` and `FALSE` when supplied as arguments to a function.
I had hoped to be able to do something about its inability to handle defined names as well. I failed. I think another section might need to be added to the Writer output which specifies the defined names. I haven't yet located any suitable documentation.
* Resolve Phpstan Messages - FINALE - Shared/OLE
Reduce number of Phpstan messages by addressing their issues. This is the last of a series of related tickets to achieve that end. Only a handful of messages will be left in Phpstan baseline after this change is merged.
Shared/Ole.php and Shared/Ole/ChainedBlockStream.php were completely uncovered in the test suite. So I wrote some tests and found they didn't work at all. There were 2 problems. The first was that ChainedBlockStream checks for a mode of `r`, but Ole invokes it with mode `rb`. ChainedBlockStream will now just check the first character of the mode.
The second was a more interesting problem. Ole was reading "an *unsigned* long". However, what it should have been reading was "a 32-bit *signed* long". The irony of this mismatch is that, once the mode problem was corrected, 32-bit Php handled Ole and ChainedBlockStream correctly, but 64-bit Php did not. The code is corrected to work properly for both 32- and 64-bit.
* Scrutinizer
2 dead assignments - sufficient to just make calls which are expected to fail.
* Additional Coverage for Reader Xls
More than 750 lines are newly covered, increasing overall coverage on my machine from 91.14% to 93.09%.
* Update FormulasTest.php
* Breaking Change to toFormattedString and 3 toArray Methods
DocBlock says `toFormattedString` returns string, but code can return int, float, bool, null, or RichText. I think the DocBlock is correct (function name clearly indicates "to string"), and the code needs to change to match it. This is not that big a deal on its own. However, some methods in `Worksheet` call this function by default - `rangeToArray`, `toArray`, and `namedRangeToArray`. All 3 can be called with a parameter so that they don't call `toFormattedString`, but, by default, they do call, and so are affected by this change. Some unit test results are changed as a result of this code change. In all those cases, an additional test is added which would match the previous result.
* Update Change Log
I often skip this till later, but, since it's a breaking change ...
* Scrutinizer, Plus Strange Cast to -0
Avoid Scrutinizer complaint by casting string to float, but ... Php decides resulted should sometimes be `-0`? That caused test failures. Very odd.
Fix#3055. Xls Reader can set vertical break specifying row 0, causing an exception. It is doubtful that Excel needs a row for a vertical break; code is changed to use row 1 if the input file specifies row 0 (or lower). Code in question has not been exercised in unit test suite. Similarly, code to set horizontal break (which probably does not have a bug) is not exercised in test suite. Finally, page order in Writer incorrectly uses value in opposite way that Reader does. A new sample is added to illustrate that these are all handled correctly; it is easier to verify this by visually comparing the source spreadsheet and the copy made from it. A unit test is also added for the same spreadsheet to formally assert that the 3 properties in question are both read and written correctly.
* Namespace-Aware Code for SheetViewOptions, SheetProtection (minor break)
This is fairly straightforward for SheetViewOptions.
SheetProtection is a bit less straightforward. All the attributes should allow for null as well as boolean; this is especially important because Excel defaults to true for some of them and false for others (existing code always treated attributes missing from the XML as false). DocBlocks are updated to indicate the defaults. The test for isProtectionEnabled is changed to reflect this reality. Also, PhpSpreadsheet has been using true/false when writing these, but Excel uses 1/0. Because of these differences, this is a breaking change, but the consequences of the breaks should be minor. Two unit test results needed to change.
Remaining areas in Reader/Xlsx which still use the namespace-unaware code include conditional formatting (internal or external), auto filters, unparsed loaded data, data validation (internal or external), alternate content, and header/footer images.
* Corrections to Xls Reader and Writer
New test and changed sample to go with code changes. Also doc change.
* 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
