Fuzzers: Disable debug logging for all fuzzers Previously, some fuzzers were generating an excessive amount of debug logging. This change explicitly disables debug logging for all fuzzers. This allows higher test throughput and makes the logs easier to read when fuzzing locally. 2023-11-03 17:49:54 +00:00			`AK::set_debug_enabled(false);`
LibGfx: Rename `JPGLoader` to `JPEGLoader` The patch also contains modifications on several classes, functions or files that are related to the `JPGLoader`. Renaming include: - JPGLoader{.h, .cpp} - JPGImageDecoderPlugin - JPGLoadingContext - JPG_DEBUG - decode_jpg - FuzzJPGLoader.cpp - Few string literals or texts 2023-02-18 16:09:16 -05:00			`auto decoder_or_error = Gfx::JPEGImageDecoderPlugin::create({ data, size });`
LibGfx: Re-structure the whole initialization pattern for image decoders When trying to figure out the correct implementation, we now have a very strong distinction on plugins that are well suited for sniffing, and plugins that need a MIME type to be chosen. Instead of having multiple calls to non-static virtual sniff methods for each Image decoding plugin, we have 2 static methods for each implementation: 1. The sniff method, which in contrast to the old method, gets a ReadonlyBytes parameter and ensures we can figure out the result with zero heap allocations for most implementations. 2. The create method, which just creates a new instance so we don't expose the constructor to everyone anymore. In addition to that, we have a new virtual method called initialize, which has a per-implementation initialization pattern to actually ensure each implementation can construct a decoder object, and then have a correct context being applied to it for the actual decoding. 2023-01-20 10:13:14 +02:00			`if (decoder_or_error.is_error())`
			`return 0;`
			`auto decoder = decoder_or_error.release_value();`
LibGfx: Remove `ImageDecoderPlugin::initialize()` No plugin is currently overriding the default implementation, which is a no-op. So we can safely delete it. 2023-07-17 13:00:37 -04:00			`(void)decoder->frame(0);`
