Previously on first `mach` run on a system, we'd display a prompt with a
20s countdown timer after which the default state directory
(~/.mozbuild) was created. Users had to wait 20s or ctrl+c and
make the directory by hand. Either way, they'd have to re-invoke
mach to run whatever command they were trying to run.
This was annoying.
This commit makes the following changes:
1) The countdown timer is replaced with "press RETURN/ENTER to continue"
2) The requirement to re-invoke mach has been removed
On first run, people now see a message telling them to press
RETURN/ENTER. Then the directory is created and whatever mach command
they requested to run is run.
While I was here, I also changed the permissions on the newly created
directory to match what it was a few lines above. Without, we're relying
on umask, which may be permissive. UNIX convention is to use a more
restrictive umask insider user directories. So this feels like the right
behavior.

This adds a simple schema for build telemetry data. We can make it more
restrictive once we have a better feeling for what kind of data we want
to submit.
This also moves more common data about the system to the telemetry handler.
We leave psutil derivied information in the resource usage data as not every
system will have psutil installed.

When I modified ehsan's patch in bug 904572 to switch to a build backend
instead of a mach command, I forgot to remove the line added to
mach_bootstrap.py to pick the mach command, which now doesn't exist.
Pymake's clinetoargv is very specific to pymake's use case, yet has been abused
as a replacement for shlex because shlex doesn't handle things properly for our
use cases.
Using pymake's clinetoargv, however, has shortcomings, and we're better off
importing its code in mozbuild, simplifying it a little, and using that
instead.
Plus, less dependencies on pymake will help kill it for good some day.
This included adding the slugid 1.0.6 python source code in /python since slugid
is now a dependency of the ./mach taskcluster-graph command, as well us updating
references that used it. Previously the implementation was in-tree.
It's been clear from user feedback that people don't realize that `mach
mercurial-setup` doesn't make any changes unless they tell it to.
Reinforce this message in the prompts printed by mach_boostrap.py.
This command is used by tab completion handlers. A user reported that
hitting tab in his shell resulted in the mercurial-setup out of date
check spewing output.
Having not configured or out-of-date tools benefits nobody. It slows
people down.
Version control tools are an integral part of working on Firefox. It is
important for version control tools to be configured optimally and to be
continuously updated so they stay optimal.
The `mach mercurial-setup` command exists to optimally configure
Mercurial for working on Firefox and other Mozilla projects.
This commit adds a pre-dispatch handler to mach that will verify
Mercurial is in a happy state. If `mach mercurial-setup` has never
executed, it will complain. If `mach mercurial-setup` hasn't been
executed in the past 31 days, it will complain.
Yes, aborting command execution and forcing people to context switch to
run `mach mercurial-setup` is annoying. First, we have carved out
several exceptions to this behavior, including detection for running in
automation, on the machines of curmudgeons, when Mercurial isn't being
used, and from non-interactive processes. Second, I argue that people
ignore optional notifications and that having persistently
poorly-configured tools is worse than a single context switch at most
every month. Therefore, the heavyhanded approach is justified.
In addition, if we did support a non-fatal notification, we would
introduce the problem of extra output from commands. If anyone was e.g.
parsing mach output, we could very likely break those systems. These
cases should be caught by the isatty() check or be running in a context
with MOZ_AUTOMATION set. But you never know.

A subsequent commit will want to access the state directory path without
possibly creating it. Make that possible by extracting path resolution
to its own function.
We're using as many defaults from the configure step as we can. We're also opinionated upon the defaults, but obviously allow most compare-locales options to be specified.
There are two exceptions:
Reference language is specified to be en-US, without optional argument. This is our in-tree command, and the reference language is known.
We always clobber the merge dir, and don't give an option not to. We default to a merge dir in the objdir, so we don't need to be that paranoid as in the standalone version.
Also, compare-locales clobbers merge-dir/browser etc, so you're not going to get / removed.
I went with gradle instead of gradlew because it's more likely to be
what users consider. And mach helpfully fixes up the uncommon typo.
This is a little hard-coded right now but I don't think it's likely
any other Gradle consumer will arise in the short term.
