2020-11-30Update libjpeg-turbo to v2.0.90 (2.1 beta1)Jonathan Wright
Update Chromium's copy of libjpeg-turbo to the latest upstream release (v2.0.90) and re-apply our local changes documented in README.chromium. Cherry-pick two additional changes from upstream to fix bugs found by fuzzers: 1) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/ccaba5d7894ecfb5a8f11e48d3f86e1f14d5a469 2) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/c7ca521bc85b57d41d3ad4963c13fc0100481084 Significant changes provided by this update: 1) A large performance boost to JPEG encoding due to an improved Huffman encoding implementation. 2) The complete removal of Arm Neon assembly code. This allows Arm's control-flow integrity security features (Armv8.3-A Pointer Authentication and Armv8.5-A Branch Target Identification) to be switched on with the appropriate compiler flags.

2019-03-01Update libjpeg-turbo to v2.0.1Chris Blume
In order to apply some performance updates from ARM, we need to update libjpeg-turbo. These performance updates have yielded a 50% speedup on some devices. This CL updates our copy of libjpeg-turbo to v2.0.1 and re-applies our local patches. This patch also deletes some extra files which were not being used locally. Update our local patch that was applied to fix http://crbug.com/398235 (https://codereview.appspot.com/229430043/). The original patch incorrectly removed "& 0xFF" which limited an array index to within that array's bounds (effectively reverting https://github.com/libjpeg-turbo/libjpeg-turbo/commit/fa1d18385d904d530b4aec83ab7757a33397de6e). Restore the mask, making the array access safe and fixing a graphical glitch which would otherwise be introduced by this change. Bug:922430 Change-Id: I3860fdb424deecf7a17818ed09a640e632e71f8d

2014-04-14Upgrade libjpeg_turbo to 1.3.1 (r1219)noel@chromium.org
Remove google.jdmarker.patch, since the fixes for CVE-2013-6629 and CVE-2013-6630 are upstream most everywhere now [1]. Version number to 1.3.1 (config.h, jconfig.h). README.chromium: "Fixed valgrind error" patch was upstreamed in r839 http://sourceforge.net/p/libjpeg-turbo/code/839. The r1188 cherry-pick was put in config.h, say that.

2011-05-17Support Motion JPEGhbono@chromium.org
This change uses the default Huffman tables when a JPEG image does not have DHT markers. When a Motion JPEG frame does not have DHT markers, it assumes a decoder uses the huffman tables suggested by the JPEG standard. Even though it is not compliant with the JPEG standard, it is useful to support such Motion JPEG because it is used by many webcams.

2010-11-01Adds libjpeg-turbo to our repository.hbono@chromium.org
This change lands the original libjpeg-turbo 1.0.1 (source files only) and NASM 2.09.2 (required for assembling .asm files on Windows) to "deps/third_party". I will send more changes to land its build files and patches to integrate it into Chrome.
