Creation of dynamic property GIFMetadataExtractorTest::$mediaPath is
deprecated in php8.2
Bug: T314099
Change-Id: I3247925a548586713d4363fc9e11625bc4c9ad46
Image metadata is usually a serialized string representing an array.
Passing the string around internally and having everything unserialize
it is an awkward convention.
Also, many image handlers were reading the file twice: once for
getMetadata() and again for getImageSize(). Often getMetadata()
would actually read the width and height and then throw it away.
So, in filerepo:
* Add File::getMetadataItem(), which promises to allow partial
loading of metadata per my proposal on T275268 in a future commit.
* Add File::getMetadataArray(), which returns the unserialized array.
Some file handlers were returning non-serializable strings from
getMetadata(), so I gave them a legacy array form ['_error' => ...]
* Changed MWFileProps to return the array form of metadata.
* Deprecate the weird File::getImageSize(). It was apparently not
called by anything, but was overridden by UnregisteredLocalFile.
* Wrap serialize/unserialize with File::getMetadataForDb() and
File::loadMetadataFromDb() in preparation for T275268.
In MediaHandler:
* Merged MediaHandler::getImageSize() and MediaHandler::getMetadata()
into getSizeAndMetadata(). Deprecated the old methods.
* Instead of isMetadataValid() we now have isFileMetadataValid(), which
only gets a File object, so it can decide what data it needs to load.
* Simplified getPageDimensions() by having it return false for non-paged
media. It was not called in that case, but was implemented anyway.
In specific handlers:
* Rename DjVuHandler::getUnserializedMetadata() and
extractTreesFromMetadata() for clarity. "Metadata" in these function
names meant an XML string.
* Updated DjVuImage::getImageSize() to provide image sizes in the new
style.
* In ExifBitmapHandler, getRotationForExif() now takes just the
Orientation tag, rather than a serialized string. Also renamed for
clarity.
* In GIFMetadataExtractor, return the width, height and bits per channel
instead of throwing them away. There was some conflation in
decodeBPP() which I picked apart. Refer to GIF89a section 18.
* In JpegMetadataExtractor, process the SOF0/SOF2 segment to extract
bits per channel, width, height and components (channel count). This
is essentially a port of PHP's getimagesize(), so should be bugwards
compatible.
* In PNGMetadataExtractor, return the width and height, which were
previously assigned to unused local variables. I verified the
implementation by referring to the specification.
* In SvgHandler, retain the version validation from unpackMetadata(),
but rename the function since it now takes an array as input.
In tests:
* In ExifBitmapTest, refactored some tests by using a provider.
* In GIFHandlerTest and PNGHandlerTest, I removed the tests in which
getMetadata() returns null, since it doesn't make sense when ported to
getMetadataArray(). I added tests for empty arrays instead.
* In tests, I retained serialization of input data since I figure it's
useful to confirm that existing database rows will continue to be read
correctly. I removed serialization of expected values, replacing them
with plain data.
* In tests, I replaced access to private class constants like
BROKEN_FILE with string literals, since stability is essential. If
the class constant changes, the test should fail.
Elsewhere:
* In maintenance/refreshImageMetadata.php, I removed the check for
shrinking image metadata, since it's not easy to implement and is
not future compatible. Image metadata is expected to shrink in
future.

This changeset implements T89432 and related tickets and is based on exploration
done at the Prague Hackathon. The goal is to identify tests in MediaWiki core
that can be run without having to install & configure MediaWiki and its dependencies,
and provide a way to execute these tests via the standard phpunit entry point,
allowing for faster development and integration with existing tooling like IDEs.
The initial set of tests that met these criteria were identified using the work Amir did in
I88822667693d9e00ac3d4639c87bc24e5083e5e8. These tests were then moved into a new subdirectory
under phpunit/ and organized into a separate test suite. The environment for this suite
is set up via a PHPUnit bootstrap file without a custom entry point.
You can execute these tests by running:
$ vendor/bin/phpunit -d memory_limit=512M -c tests/phpunit/unit-tests.xml
