still good, pleasently surprisingly

Other Team Business[edit]

  • Antoine https://phabricator.wikimedia.org/T145819
    • "Jobs invoking SiteConfiguration::getConfig cause HHVM to fail updating the bytecode cache due to being filesize limited to 512MBytes"
    • Can we have scap to trigger a generation of /var/cache/hhvm/cli.hhbc.sq3 or maybe just delete it ? It keeps growing until that reach wfShellExec imposed ulimit.

Program 6: Outcome 2: Objective 2: Set up a continuous integration and deployment pipeline to publish new versions of an application to production via testing and staging environments that reliably reproduce production[edit]

Due: End of this quarter
Complete build phase of release pipeline
    • Build test variant
    • Run test entrypoint w/developer feedback - services dependency
    • Build production variant w/developer feedback - services dependency
    • Tag production container
    • Push to production docker registry - ops dependency - staging namespace

Quaterly non-goal "Work"[edit]

Program 1: Outcome 1: Objective 1: Scap (Tech Debt Sprint FY201718-Q2)[edit]

workboard
  • Trying to pin down a time for Chad and Mukunda to meet (weekly) about this objective, not yet scheduled
  • Investigated git the issue with submodules wasting a lot of space for duplicated git packs/objects


Program 1: Outcome 5: Objective 1: Maintain existing shared Continuous Integration infrastructure[edit]

Goal: A generalized POC for a docker-based CI.
https://phabricator.wikimedia.org/project/view/3008/ (shipyard workboard)
  • struggling with building an image using docker, limited and easy to screw up :)
  • Homegrow CI tool to build vs operations one for prod images
  • Still "docker pull" random image from docker hub
  • Not sure yet how to exactly run the commands in the container
  • We need CACHE (similar to Castor)

There are a few experimental jobs here and there. But nothing will be seriously migrated until the infrastructure is ready.


Program 1: Outcome 6: Milestone 1: Maintain Gerrit[edit]

Program 1: Outcome 6: Milestone 2: Maintain Phabricator[edit]

  • Created tools for managing custom forms
    • Copy an existing form, maintaining it's default values / hidden fields and field ordering.
    • Changed custom fields to default to hidden
  • Updated the script for moving project hierarchies
    • Now it's possible to move an existing subproject into a different parent project
    • This is not particularly safe and it is generally inadvisable to use it except for extraordinary situations.
      • The script does not deal with project members so it is especially not advisable for projects where the membership matters


Program 1: Outcome 5: Objective 1: MW Nightlies server[edit]
