Actions

Hot Bugs

(Important bugs for which we need to find owners or additional help. If known, please include suggested team or knowledge needed to advance the bug.)

Orange Factor
Stability
  • bug 885668 - needs owner - around the #10 topcrash position in both 24 and 25
Other

The Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (akeybl/lsblakk/bajaj)

?? bugs (?? bugs last week)
?? bugs (?? bugs last week)
Unresolved Aurora 54 Trackers (non-security, not tracked for Beta) Unresolved Beta 145 Trackers (non-security)

Build Changes (gps)

(Build changes of which engineers should be aware.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

6.5 hour tree closure planned for Saturday, July 13 from 1200 PDT to 1830 PDT. Master tracker is bug 889996.

Summary of work that will be done and the impact:

  • Failover of the new Bugzilla environment will be tested between data centers.
    • Impact: Bugzilla (bugs.mozilla.org) may experience brief interruptions in service during the window
  • Buildbot database failover will be tested.
    • Impact: trees will be closed, so no negative impact
  • http://build.mozilla.org will move to new releng web cluster
    • Impact: may experience a brief interruption in service to build.mozilla.org though none is expected; in addition the trees will be closed so there should be no impact to builds during this time
  • Database servers across the infrastructure will have their masters changed in preparation for upgrades
    • Impact: These failovers happen in a couple of seconds, some apps may fail queries during this time causing an HTTP 500 error or needing a client refresh
  • Backend load balancers in SCL3 will be upgraded from 1g to 10g network connectivity
    • Impact: some backend databases may experience a few seconds of service interruption, most of these services only impact developer/releng resources that will already be unavailable during the tree closure

Key Issues

(Non team specific issues that impact engineering.)
