Mozilla pushes - June 2014

Here's June 2014's  analysis of the pushes to our Mozilla development trees. You can load the data as an HTML page or as a json file

Trends
This was another record breaking month with a total of 12534 pushes.  As a note of interest, this is is over double the number of pushes we had in June 2013. So big kudos to everyone who helped us scale our infrastructure and tooling.  (Actually we had 6,433 pushes in April 2013 which would make this less than half because June 2013 was a bit of a dip.  But still impressive :-)

Highlights
  • 12534 pushes
    • new record
  • 418 pushes/day (average)
    • new record
  • Highest number of pushes/day: 662 pushes on June 5, 2014
    • new record
  • Highest 23.17 pushes/hour (average)
    • new record

General Remarks
The introduction of Gaia-try in April has been very popular and comprised around 30% of pushes in June compared to 29% last month.
The Try branch itself consisted of around 38% of pushes.
The three integration repositories (fx-team, mozilla-inbound and b2g-inbound) account around 21% of all the pushes, compared to 22% in the previous month.

This week in Mozilla Releng - July 4, 2014

>> Friday, July 04, 2014

This is a special double issue of this week in releng. I was so busy in the last week that I didn't get a chance to post this last week.  Despite the fireworks for Canada Day and Independence Day,  Mozilla release engineering managed to close some bugs. 

Major highlights:

  • Armen, although he works on Ateam now, made blobber uploads discoverable and blogged about it.  Blobber is a server and client side set of tools that allow Releng's test infrastructure to upload files without requiring to deploy ssh keys on them. 
  • Callek and Coop, who served on buildduty during the past two weeks worked to address capacity issues with our test and build infrastructure.  We hit a record of 88,000 jobs yesterday which led to high pending counts.
  • Kim is trying to address the backlog of Android 2.3 test jobs  by moving more test jobs to AWS from our inhouse hardware now that Geoff on the Ateam has found a suitable image.
  • Rail switched jacuzzi EBS from magnetic to SSD.  Jacuzzis are similar pools of build machines  and switching their EBS storage from magnetic to SSD in AWS will improve build times.
 Completed work (resolution is 'FIXED'):
In progress work (unresolved and not assigned to nobody):
