Hi,
We had a quick meeting focused on how to not regress Talos.
Attendance: Taras Glek, Ehsan Akhgari, Clint Talbert, Nathan Froyd, Dave
Mandelin, Christina Choi, Joel Maher
Notes:
* Clint's Automation&Tools team is improving Talos reporting abilities.
We should have much better tools for comparing performance between 2
different changesets soon.
* Talos is now significantly easier to run locally than it used to be.
Expect blog posts from Joel/Ehsan
* Joel will revisit maintaining Talos within mozilla-central to reduce
developer barriers to understanding what a particular Talos test result
means. This should also make Talos easier to run
* We will implement a formal policy on Talos impact of merges.
** focus on perf tracking on inbound, to avoid merge pains
** We will extend the current merge criteria of last green PGO changeset
to also include "good Talos numbers"
* Nathan Froyd will look at historical data for the last Firefox nightly
release cycle to come up with threshold numbers for backing out commits
* Joel/Ehsan will look into using mozregression with talos so we can
bisect performance regressions locally. We will also consider doing
something similar on try.
Taras
