1422988 - Failure suggestions depending on multiple lines

Status: NEW

• Failures can show up in the log summary, but the root cause is earlier in log and not part of the log summary. This often applies to infrastructure issues.
    • If such a failure is shown in the log summary, the bug should only be suggested if the other failure line has been found in the X lines before that failure. X=500?
    • Example: https://bugzilla.mozilla.org/show_bug.cgi?id=1415526

Is this still relevant and if so how often is it applicable?

Yes. For every task failure which currently doesn't mention the currently executed test or the one which ran last, this has to be manually checked in the log at the moment. Another use case are crashes where the line with the failure summary is not helpful (e.g. mentions a wrapper file) and the real Firefox file mentioning the issue is further down.
