Rule of Thumb

Status code:

  • OOAD: In analysis or design phase.
  • WIP: working on WIP patch.
  • feedback?(f?): WIP is ready for feedback grant.
  • feedback+(f+): Get positive feedback.
  • review?(r?): patch is under review
  • review+(r+): get review+ and ready to check-in
  • review(r): review a patch.
  • feedback(f): feedback a patch
  • land: patch check in.
  • debug: Figure out the root cause of a bug/ try to repro that bug, etc...
  • file: file a bug
  • PTO: take personal leave
  • study: Spend time on domain knowledge study, such as multimedia transport technology, compress format, real-time rendering.
  • presentation
    • Write a personal blog, which is relative to work, such as articles on MozTech, or what you experience in a work week.
    • WIKI/ MDN article writing.
    • If you write a technical blog or anything relative to work, it's welcome to share it on weekly report.
    • Do a presentation of technical topics

Status code combination rule
Combine status code with "|". For example 

** OOAD|WIP

Which means you work on both OOAD and WIP in the last week.

land status code
If your patch is target for specific branch, instead of central, postfix branch version. For exp 

** land(1.4)

  • bug 976656 - crash in mozilla::gfx::DrawTargetCairo::CreateSourceSurfaceFromNativeSurface(mozilla::gfx::NativeSurface const&) const (edit)
    • debug
    • The bug has been set to resolved now, however the actual root cause is not clear. This bug probably not directly originated to the function CreateSourceSurfaceFromNativeSurface() itself. The potential root cause maybe dues to the stack overflow cause by BufferUnrotate() (bug#970007), which destried its return address.
  • bug 995680 - Camera preview does not use hw composer
    • debug
    • The previewing of Camera app now using TiledThebeLayer, and it was improperly set to scrollable. Which results in the composition must be done by GPU.
