Intro

Clang packages use tooltool to deploy itself run time. The binaries are hosted on relengweb1.dmz.scl3.mozilla.com (use your LDAP account) and accessible from http://runtime-binaries.pvt.build.mozilla.org/tooltool/.

Clang build is made by http://hg.mozilla.org/mozilla-central/file/tip/build/unix/build-clang/build-clang.py script. You may want to use this script to discover the recent used version of clang.

How to add a new version

  • Manifests should be attached to the bug by a developer
  • ssh to relengweb1.dmz.scl3.mozilla.com
  • Download files
mkdir ~/tooltool
cd ~/tooltool
rm -i *
# get latest setup.sh if its manifest was changed
wget https://hg.mozilla.org/mozilla-central/raw-file/default/build/unix/build-clang/setup.sh
# download new clang packages
wget http://people.mozilla.org/~user/clang-linux.tar.bz2
wget http://people.mozilla.org/~user/clang-linux64.tar.bz2
wget http://people.mozilla.org/~user/clang-osx.tar.bz2
# Fix permissions
chmod 644 *
  • Copy files to the tooltool directory. Use the "digest" field from the generated manifests as target file name:
for f in clang-*.tar.bz2; do
  ls -l $f
  sudo cp -vi $f /var/www/html/runtime-binaries/tooltool/sha512/$(sha512sum $f | cut -f1 -d " ")
done
  • repeat the same step for setup.sh if needed
