See skia/include/core/SkMilestone.h for the milestone number. + +Current upstream hash: 4655534302e6a3601c77eae70cc65b202609ab66 (milestone 79) + +How to update +============= + +To update to a new version of Skia: + +- Clone Skia from upstream using the instructions here: https://skia.org/user/download + Usually: `git clone https://skia.googlesource.com/skia` +- Checkout the wanted revision (`git checkout -b <hash>`). See below for the current + hash. +- Copy the entire source tree from a Skia clone to mozilla-central/gfx/skia/skia + (make sure that . files are also copied as .gn is mandatory). +- Download gn: cd gfx/skia/skia/bin && python fetch-gn && cd - + Note that these scripts might need Python 2.7. Please use a virtualenv if needed. +- cd gfx/skia && ./generate_mozbuild.py + +Once that's done, use git status to view the files that have changed. Keep an eye on GrUserConfig.h +and SkUserConfig.h as those probably don't want to be overwritten by upstream versions. + +This process will be made more automatic in the future. + +Debug +===== + +In case of issues when updating, run the command manually. +For example, if the following error occurs: +`subprocess.CalledProcessError: Command 'cd skia && bin/gn gen out/linux --args='target_os="linux" ' > /dev/null && bin/gn desc out/linux :skia sources' returned non-zero exit status 1` +Run: +`cd skia && bin/gn gen out/linux --args='target_os="linux"'` +and look at the errors. |
