Antoine below, probably better by email:::


  • Composer / mediawiki/vendor for Jenkins jobs

Jan is switching our jobs on master to use composer instead of vendor The REL/wmf branches versions of the jobs use vendor ( ).

Problem: when we cut the branch, the wmf jobs will fail until vendor.git is updated. The branch cut needs a new step:

   * update composer
   * update vendor.git
   * get tests to pass and +2
   * REL/wmf branches based jobs pass again (cause vendor has been updated)


  • Where is the branch cut doc/process?
  • Gotta update the make-release make-wmf-branches scripts
  • automatically build and commit mediawiki/vendor (composer)
  • can be done just when we cut the branch (Monday). Leave us a day to update vendor before first deployment (Tuesday)


  • Pool to be raised from 1 standby / max of 5 to 10/20 probably
  • Antoine/Andrew talked about potential overloading of the labs infra. The scheduler should refuse instant creations in such case.
