Now that bug 995417 has landed, we have coverage against gecko attempting to connect to a non-loopback name (eg external resource outside of the build network) whenever MOZ_DISABLE_NONLOCAL_CONNECTIONS is defined. 

https://hg.mozilla.org/mozilla-central/rev/51342b493983 defined it in:
build/automation.py.in
build/automationutils.py
build/mobile/remoteautomation.py
testing/xpcshell/runxpcshelltests.py

However, there are other places we set env defines (see bug 1023483 comment 3), so there are still test suites for which bug 995417 is not enabled.

These try runs:
https://tbpl.mozilla.org/?tree=Try&rev=c4fe727a12d1
https://tbpl.mozilla.org/?tree=Try&rev=03c4764ac26a
(latter for PGO)

...shows that the define is missing for:
* talos (all valid platforms)
* jetpack (all valid platforms)
* marionette (all valid platforms)
* marionette-webapi (all valid platforms)
* gaia-unit (all valid platforms)
* gaia-integration (all valid platforms)
* gaia-ui-test (all valid platforms)
* mochitest (b2g emulator only)
* reftest/crashtest (b2g emulator only)
* xpcshell (b2g emulator only)

This try run removes the check for MOZ_DISABLE_NONLOCAL_CONNECTIONS:
https://tbpl.mozilla.org/?tree=Try&rev=a06dd6870851

...so should show us what will need fixing once we define it everywhere.

Another try run, except this time with the error message prefixed with "Automation Error:" so that the TBPL parser will find them for us - and the MOZ_CRASH removed, so we can find several in one go:

I can believe this, but I'm also pretty sure that several bugs fixed for bug 995417 were found only on B2G emulator: bug 1023638 (xpcshell) and bug 1024588 (seen during mochitests), for instance.

Note that for this run, the jobs appear passing, but that's just because buildbot/mozharness doesn't check for "Automation Error:". Opening the logs does show TBPL-parsable output however, so it's slightly more useful than the comment 0 try run.

Yeah that puzzled me; though we use gecko for other parts of the b2g emulator end-to-end job (eg xpcshell; though that should already be covered?), which are what is crashing in that try run, rather than the mochitests/... themselves.

Ah in fixing bug 1038943, khuey found that the env wasn't being passed in correctly. Once bug 1039019 is fixed we'll need to revert his workaround from https://bugzilla.mozilla.org/attachment.cgi?id=8456564&action=diff#a/testing/mochitest/runtestsb2g.py_sec3

Mass-closing old bugs I filed that have not had recent activity/no longer affect me.

Btw a better method is to file bugs for specific harnesses like Marionette (bug 1272255).

This was a meta bug
