util/bot/UPDATING

This directory consumes tools from other repositories for use on the
bots. To update to newer revisions, follow these instructions:

DEPS: Set all revisions to those used in Chromium, found at
   https://chromium.googlesource.com/chromium/src/+/master/DEPS (Search for the
   corresponding repository name.)

go/bootstrap.py: Set TOOLSET_VERSION to the latest release of Go, found at
    https://golang.org/dl/.

update_clang.py: Set CLANG_REVISION and CLANG_SUB_REVISION to the values used in
    Chromium, found at
    https://chromium.googlesource.com/chromium/src/+/master/tools/clang/scripts/update.py

vs_toolchain.py: Set the hash in TOOLCHAIN_HASH to the toolchain
    used in Chromium, found at _GetDesiredVsToolchainHashes
    https://chromium.googlesource.com/chromium/src/+/master/build/vs_toolchain.py
    This may require taking other updates to that file. If updating MSVS
    version, also update TOOLCHAIN_VERSION accordingly.

The .sha1 files correspond to files downloaded from Google Cloud Storage. To
update, place the updated files in their intended location and run:

    upload_to_google_storage.py -b chromium-tools FILE

        tar -czf cmake-linux64.tar.gz cmake-linux64/

    The current revision was built against cmake-3.5.0.tar.gz.
