Some refactoring is required to make the StructuredOutputParser a suitable drop-in replacement for the DesktopUnittestOutputParser and others, particularly implementing or establishing the obsolescence of things like tbox_print_summary and the "crashed" and "leaked" statuses.

We want a tuple or list in the in-tree config, something like "structured_suites", if we find it, we use the StructuredOutputParser, if not, we proceed exactly as before. This is probably a different bug, but I'd like to propose something in mozharness.mozilla.testing.unittest whose purpose is to de-duplicate logic in *_unittest.py scripts and perhaps others for interpreting options, feature detection, and whatever other directives from an in-tree config. Armen, this seems really closely related to some proposals you've had. I see this as a blocker for structured logging work I'm presently engaged with. Let's put our heads together to decide how to approach this.

I want jlund to be in the loop for this since he wrote the original output parser IIRC. The second part of 3.1 [1] should help us by allow us reading more info from the in-tree configs. I'm still working to get approval and coverage to work on it. If you're happy to block on that it would be great. Otherwise, you can start by hacking the current in-mozharness configs. What do you think? [1] https://wiki.mozilla.org/User:Armenzg/Proposals/Mozharness_changes#Move_and_extend_information_used_from_in-tree_mozharness_configs

I'll definitely flag jlund for feedback once we get to that point, thanks. I'm thinking that what I want to do here is exactly the realm of "Extend which information is read from in-tree configs", but whether we read it from in-tree or elsewhere, we're making something (the output parser to be used) configurable, where it wasn't before. I'm strongly inclined to get this from in-tree because that seems much easier than hacking existing configs to have it apply only to certain branches. In part because there are also a small number of modifications to logging in harness that really ought to land precisely when this swap is made, and in part because my mental model of how configuration coming from in tree works is much better developed than how this might work from in mozharness/buildbot. But I'm sure that this second point could be addressed with a little guidance :) What sort of approval does this require, generally? This impacts proposed structured logging deliverables for Q4; I could certainly justify working on it.

I think we're fine with reading from the tree. I believe jlund would be OK with reading this info from the tree. I assume his approval as module owner is good. In this bug you're focused on a subset of the info I want. With Bug 1070041 I want to make it a more general approach. I don't know yet when I can tackle bug 1070041 as I'm still working on mulet reftests. I hope it will be in less than 2 weeks.

Great, thank you for the info Armen. It doesn't sound critical which modification lands first as long as we're all on the same page. I think I just need to deliver an output parser based on a config and make it work independent of whether the config comes from in tree or out.

This is what I'm after. This shouldn't have an observable effect without a corresponding tree config change. Adding "--log-raw=-" tells mozlog to log line-delimited json to stdout instead of tbpl style formatted strings. On ash (turned on for marionette desktop, the failures are my addition): https://treeherder.mozilla.org/ui/#/jobs?repo=ash&revision=140ee4ffe0f4

I think this a great proposal. Getting more things configurable, especially in-tree, empowers devs and increases turn around time. tests that stem from the tree should have its parsing logic live within the tree too. will look at patch shortly.

Thanks for the feedback! I'll update and run through ash with this turned on for mochitests to see how we fare.

This is a lot like the prior patch, but I got rid of the idea of each script adding --log-raw=- because we can already do this through the in-tree config, and we may move to a version of this where we don't parse the raw log from stdout in the medium term. On ash with a recent m-c as a sanity check: https://treeherder.mozilla.org/ui/#/jobs?repo=ash&revision=68405d63b588 On ash with the structured output parser turned on for mochitest and xpcshell: https://treeherder.mozilla.org/ui/#/jobs?repo=ash&revision=4772aa3dbb3e There are a few things in that second push to sort out before we can turn this on, but with this patch landed I can at least push things to try and toggle things with the in-tree config to get them straightened out.

I know I'm a little late for Halloween, but the scary part is the function we're using today: http://hg.mozilla.org/build/mozharness/file/baa1b3294d2d/mozharness/mozilla/testing/unittest.py#l159 You might notice the return_code parameter is ignored altogether. Some users of StructuredOutputParser (w-p-t and marionette) do or will be able to use a return code to contribute to job status, so we're doing a little better there but haven't fixed the underlying issue causing us to ignore return codes in the first place.
