[Buildbot-devel] Question about mail notifier.

[shiny knight]

The main issue, for me, has always been how to find the step that failed. Found at least a couple of solution, but none that is explained on the manual.

If you have for example 4 steps, and the 2nd will fail; you need to go backward in the logs to find the log of that specific step. Because the example on the manual grab the last step logs and print the last X lines from it, so it never tells you how you actually access the log object.

One way is to search for an "error" log; but if 2 or more steps fail in the same builder, then it won't work, because it would just take the last one. Otherwise you need to loop trough the whole log object and extrapolate the error lines, building a custom createSummary function in your step, that search for whatever error you need to convey.

AFAIK, the documentation do not mention how can you access to specific logs for a specific step, nor if you can find the status of a specific test. If this info is there; is not really pointed out.
Examples on the topic would be highly appreciated on the manual. There are plenty of config tips, but on the customization, the amount of info on the manual is not enough.

Would be possible to activate a wiki on the Buildbot page, so people can contribute? Mailing lists are awesome but search trough them is a jump in the unknown :)
