We would eventually like to break up the test package into individual test suite packages to avoid overhead of downloading on unzipping the monolithic archive on each test machine (bug 917999).

A first step would be to move the cppunit tests into their own package. They are the largest component of the test archive and are likely to grow larger as we move more tests out of make check (bug 992323). For instance, removing gtest from make check requires adding the gtest libxul to the test package which is 80+ MB on Linux.
This special cases the cppunit tests and moves them into their own test package.

We might eventually want to move every test type into individual packages, but I thought there was enough benefit in getting the cppunit tests out of the main test package that it was worthwhile doing that prior to coming up with a generic solution that handles each test type.

This will require mozharness changes before it can be landed, but I wanted to hold off on that until it looked like this approach would be ok.

My thought for mozharness would be to download the main test package and then attempt to download the cppunit test package if we are running those tests. It would not be an error if the cppunit test package is not present since we wouldn't expect these changes to be present on every branch initially.

I don't have much opinion besides the fact that i really hate those rules, but you're merely inheriting what's already awful. Maybe ted has something to add.

This seems fine (given the existing awfulness). I assume you're going to have to make mozharness smart enough to fall back to the existing test package so you don't break things?

I have a mozharness patch in progress to handle this, but I didn't want to waste someone's time reviewing that if my packaging changes weren't acceptable :)

Patch to attempt to download cppunit test package if available

Review of attachment 8479890 [details] [diff] [review]:

lgtm :) this will be fantastic to have. My only concern is that ERROR_LEVEL=INFO seems to get ignored for at least some part of _download_unzip (see in line comment). I'll r+ so this isn't blocked but my gut says we should fix this soon. What do you think?

OOC - what branch or where will firefox-34.0a1.en-US.linux-i686.cppunit.tests.zip exist? Your ash jobs looks like it never exists but I suspect that is due to the pipes not being connected?

I _think_ this will work with proxxy. looking at https://bug1014659.bugzilla.mozilla.org/attachment.cgi?id=8479890 it just fails to find the url like the non proxy equivalent

Thanks for catching that. It was hardcoded to ERROR in download_proxied_file in proxxy.py, so I've
changed that to use the passed in error level.

I'm planning to test my packaging change on Cedar once the mozharness patch lands. It is working fine locally, and I've done some try runs with it so I'm not expected problems, but you never know.

The 'test_url' itself comes from buildbot. I think in the future when we break out each suite into individual test packages we'll want something in the config that tells us the test package name but I don't think we need this right now.

With the changes in this patch I thought it would be good to have a specific check. This should only show up if the download fails.

Thanks for the review!

Merged to production, and deployed.
Depends on: 1062910
Sorry about the bustage on the last patch.

I think this is better - I only attempt to download the cppunit test package if the main test package is missing the cppunittest directory. This avoids having to change mozharness to allow for failed downloads.

Tested it on Ash here: https://tbpl.mozilla.org/?tree=Ash&rev=65b8285608ad

I should have caught that proxxy change. We don't want to fatal in proxy call as proxxy will have lots of urls to try and we should only fatal if error_level is fatal and all urls are exhausted. we had so many usw2 issues/bugs last week. hiding this in a condition will limit this to a limiting testing env so this is good
since this uses _download_unzip and that is hooked up to proxxy, we should inform catlee/Miroshnykov about this as it will be a new file and I don't know if this requires plumbing on the proxy server.
catlee, gmiroshynkov is this likely to cause problems again?

Ted has been working on Bug 1059943 which would make this patch unnecessary. At this point, I'm happy to stop work on this patch rather than break more things.

No, that proxxy change was completely my fault. I was trying to address your comment about 'ERROR' showing up in the tbpl log and I only tested it locally since it seemed like a small change. I should have requested a new review and/or tested it on Ash before landing.
Everything should work fine as long as error_level is not set to FATAL in self.download_file() inside proxxy.py

Hardcoding it to ERROR was kind of a hacky workaround because I wasn't brave / familiar enough to refactor mozharness to do this properly.

I guess we can replace ERROR with WARNING or something like that, as a single download timeout / failure inside proxxy is not that rare and we can recover from it anyway, but this is probably outside the scope of this bug.

The last version of the patch doesn't work (see try run [1])

The problem is at [2], which causes the cppunit package to be downloaded rather than the main test package:
    if f['name'].endswith('tests.zip'):  # yuk

This patch uses 'tests.cppunit.zip' rather than 'cppunit.tests.zip' to avoid this. I didn't hit this in local testing because I was passing in the path to the tests zip on the command line.

I've also added code to download the separate package for the b2g emulator. The last patch added this accidentally for b2g_desktop, which doesn't currently have cppunit tests scheduled against it. I don't think there is any harm in leaving it in, but I can remove it if you prefer.

if we have no near intentions of doing cpp on b2g desktop, I think we should remove it suggests the script supports it.

No worries, pushed to https://hg.mozilla.org/build/mozharness/rev/213d460025e0

Maybe it doesn't matter, but this change will mean that the binaries in the cppunittest package won't be universal binaries on universal OS X builds. I guess we probably don't test on non-64-bit OS X nowadays anyway?

I don't think it matters for running tests in automation, but now that you've pointed it out, it bothers me and I'll try to fix it.

Looks like some more problems have shown up [1]:

- we're attempting to use the cppunit test package as the installer (again)
- and we're messing up the url for the jsshell package.

My original intention was to start on bug 917999 here because the cppunit tests were the largest chunk of the tests zip and would give us the most benefit. With the new plans, I don't think there is any point continuing here.
