What data do we have? | |||
== How Can We Use It To Get to the Bottom of Crash Problems == | |||
QA activities -- who, what, when, where, and how: | |||
* getting to a reproducible environment/test case | |||
** identifying a common config | |||
*** OS version, hardware & driver correlations | |||
*** addon/plugin correlations | |||
*** graphics cards and driver correlations | |||
*** urls, domains, locales/regions of sites visited | |||
*** common user actions in comments | |||
**** e-mailing some some users?... (new automated system coming on-line) | |||
*** calibrating which Product Releases where the crash is seen. | |||
* Time & Regression Ranges -- looking at the various forms of time data: | |||
** Finding Spikes and Volume Regressions | |||
*** time of crash (breakpad/socorro dup reports) https://bugzilla.mozilla.org/show_bug.cgi?id=579136 | |||
*** time since last crash | |||
*** time since start up (uptime) | |||
*** time of the build | |||
*** install time | |||
* Connecting to External and Other Events | |||
** Plugin/Addon Releases | |||
** Web Site Changes | |||
** Firefox/Gecko Source Code Changes | |||
** Build Environment Changes... new compliers, build configs. | |||
* With a reproducible test case... | |||
** reduced test case | |||
** crash recorded on VM... | |||
* developer investigations | |||
** finding problems though source inspection | |||
*** using regression ranges to examine change sets | |||
** Running Minidupms in the debugger. | |||
