[Buildbot-devel] How to handle logfiles when multiple tests are run in a single buildstep

[Fulvio Cervone]

I guess that i did misunderstood.

Anyway I think that as I mentioned, he can easily get the data out of the single log file just with a bit of grep and sed/awk; if he wants to dump the logs in an external file. Then he could just make a web page to present the single links to each of the tests and link it to the waterfall page (or in any other area that he see fit); I saw some nice examples in the web folder, that I will probably use to present my test results.

It sound easier in this way, compared to writing a custom subclass, but that's just me (maybe is enough to overload the createSummary and put the logic there ? It will be a pain thou to create single links for each test without some heavy data processing on the main log file)

Anyway an example of what Bill want to accomplish would help :)

If having a shared log would work, you can just have all of the tests log to stdio and use the existing log, greping through for whatever individual test you need.
