Raw Normal View History

Make image decoding more fault resistant, less verbose. This change address what happens when a jpeg is partially downloaded before failing. Many browsers will render it anyway: we want Skia to do the same. The JpegTest takes a perfectly cromulent jpeg file and only passes into the ImageDecoder the first half of the image. We then verify that the image decoder returns a valid bitmap of the correct dimensions. We also fixed some png library errors, including issue 1691. Also, suppressed the majority of warnings from using libpng and libjpeg. By default, most warnings are *not* suppressed in debug mode. If you have a debug binary and wish to suppress warnings, set the following environment variables to true skia_images_png_suppressDecoderWarnings skia_images_jpeg_suppressDecoderWarnings or from within a program that links to Skia: #if defined(SK_DEBUG) #include "SkRTConf.h" SK_CONF_SET("images.jpeg.suppressDecoderWarnings", true); SK_CONF_SET("images.png.suppressDecoderWarnings", true); #endif I tested this, before (control) and after these changes (test), on 364,295 skps from the cluster telemetry. - number of errors+warnings in control = 2804 - number of errors+warnings fixed = 2283 - number of PNG verbosity fixed = 2152 - number of PNG error fixed = 4 - number of PNG segfault fixed = 3 - number of PNG errors changed to warnings = 62 - number of JPG verbosity fixed = 26 - number of JPG error fixed = 91 Not all errors and warning have been fixed. These numbers were generated using the find_bad_images_in_skps.py program. This program may be useful going forward for testing image-decoding libraries on skp files from the cluster telemetry. find_bad_images_in_skps.py depends on the test_image_decoder program, which simply executes the SkImageDecoder::DecodeFile function and uses its exit status to report success or failure.

Use DEFINE_TESTCLASS_SHORT macro in tests. The three version of DEFINE_TESTCLASS macro is deprecated and thus just use the simple, short one.

Make image decoding more fault resistant, less verbose. This change address what happens when a jpeg is partially downloaded before failing. Many browsers will render it anyway: we want Skia to do the same. The JpegTest takes a perfectly cromulent jpeg file and only passes into the ImageDecoder the first half of the image. We then verify that the image decoder returns a valid bitmap of the correct dimensions. We also fixed some png library errors, including issue 1691. Also, suppressed the majority of warnings from using libpng and libjpeg. By default, most warnings are *not* suppressed in debug mode. If you have a debug binary and wish to suppress warnings, set the following environment variables to true skia_images_png_suppressDecoderWarnings skia_images_jpeg_suppressDecoderWarnings or from within a program that links to Skia: #if defined(SK_DEBUG) #include "SkRTConf.h" SK_CONF_SET("images.jpeg.suppressDecoderWarnings", true); SK_CONF_SET("images.png.suppressDecoderWarnings", true); #endif I tested this, before (control) and after these changes (test), on 364,295 skps from the cluster telemetry. - number of errors+warnings in control = 2804 - number of errors+warnings fixed = 2283 - number of PNG verbosity fixed = 2152 - number of PNG error fixed = 4 - number of PNG segfault fixed = 3 - number of PNG errors changed to warnings = 62 - number of JPG verbosity fixed = 26 - number of JPG error fixed = 91 Not all errors and warning have been fixed. These numbers were generated using the find_bad_images_in_skps.py program. This program may be useful going forward for testing image-decoding libraries on skp files from the cluster telemetry. find_bad_images_in_skps.py depends on the test_image_decoder program, which simply executes the SkImageDecoder::DecodeFile function and uses its exit status to report success or failure.
