Andrew Halberstadt a3a1865e5a Bug 1368438 - Add -j to mach try, r=chmanchester
The -j try syntax specifies a "job" task. Job tasks are different from
unittests in that they typically don't require a build and run from the
source tree. Examples include linters (eslint, flake8, etc), python tests
(mozbase, mochitest, etc) and misc things like doc generation.

Sometimes, developers might only want to run a specific "job" task with a
syntax like "./mach try -j mozbase".

This means a few assumptions need to be broken in |mach try|. Platforms
and unittests should no longer be required if -j was specified. Most of
the changes in this patch revolve around dealing with those broken
assumptions.

"""Autotry is in beta, please file bugs blocking 1149670.
Push the current tree to try, with the specified syntax.
Build options, platforms and regression tests may be selected
using the usual try options (-b, -p and -u respectively). In
addition, tests in a given directory may be automatically
selected by passing that directory as a positional argument to the
command. For example:
mach try -b d -p linux64 dom testing/web-platform/tests/dom
would schedule a try run for linux64 debug consisting of all
tests under dom/ and testing/web-platform/tests/dom.
Test selection using positional arguments is available for
mochitests, reftests, xpcshell tests and web-platform-tests.
Tests may be also filtered by passing --tag to the command,
which will run only tests marked as having the specified
tags e.g.
mach try -b d -p win64 --tag media
would run all tests tagged 'media' on Windows 64.
If both positional arguments or tags and -u are supplied, the
suites in -u will be run in full. Where tests are selected by
positional argument they will be run in a single chunk.
If no build option is selected, both debug and opt will be
scheduled. If no platform is selected a default is taken from
the AUTOTRY_PLATFORM_HINT environment variable, if set.
The command requires either its own mercurial extension ("push-to-try",
installable from mach mercurial-setup) or a git repo using git-cinnabar
(available at https://github.com/glandium/git-cinnabar).
