The Windows content indexing service has been known to scan the objdir.
This can add significant system overhead and slow down builds or
subsequent operations. The objdir is meant to be a short-lived black box
and there really isn't a major benefit to indexing it.
There is a file attribute on Windows that disables content indexing.
This commit adds a utility function for creating a directory and
optionally disabling indexing on it. We call it at the top of
`mach build` to ensure the objdir as content indexing disabled.

We don't process IPDL and WebIDL files during artifact builds. The
backend shouldn't need to care about them.

After this change, we no longer write any .cpp files to the objdir
during config.status for artifact builds.
As part of this, we stopped generated webidlsrcs.mk and the build broke
because of an unguarded use in a Makefile.
After this change, only 102/3366 files in the objdir after
`mach configure` are not a) in _virtualenv b) named backend.mk
c) named Makefile (~950 each of backend.mk and Makefile).

I can't think of a good reason why unified C++ files need to exist
during artifact builds. Let's not write them in this build config.

No measureable change in performance on Linux. But on Windows where file
creation is in the ~1ms range, this will surely result in a speedup of
several hundred milliseconds.
We are still generating some .cpp files during artifact builds. This will be
addressed in subsequent commits.

As previous measurements have shown, creating/appending files
on Windows/NTFS is slow because the CloseHandle() Win32 API takes
1-3ms to complete. This is apparently due to a fundamental issue
with NTFS extents. A way to work around this slowness is to use
multiple threads for I/O so file closing doesn't block execution
as much.
This commit updates the file copier to use a thread pool of 4
threads when processing file copies. Additional threads appear
to have diminishing returns.
On my i7-6700K, this reduces the time for processing the tests install
manifest (24,572 files) on Windows from ~22.0s to ~12.5s in the best
case.
Using the thread pool globally resulted in a performance regression
on Linux. Given the performance sensitivity of manifest copying,
I thought it best to implement a slightly redundant non-Windows
branch to preserve performance. For the record, that same machine
running Linux is capable of processing nearly the same install
manifest (24,616 files) in ~2.2s in the best case.

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.

self._pushhead_cache no longer exists. But self._tree_cache does!
This was causing AttributeError when running `mach artifact clear-cache`
and other misc `mach artifact` sub-commands.

Currently, config.status runs `mach artifact install`. mach commands prefix
output lines with elapsed time by default. When running from `mach build`,
there will be 2 sets of times in `mach artifact install` output lines.
When config.status is run directly, there will be no times printed
except for `mach artifact install`. It is weird both ways.
Fix it by not printing lines when running `mach artifact install` from
config.status.

Opt-in by adding --enable-gradle-mobile-android-builds.
Gradle dependencies (including the Android-Gradle plugin) are assumed
to be present. Local developers will fetch them from the jcentral
repository.
Android-specific Maven dependencies are shipped as "extras" with the
Android SDK, and should be found automatically by the Android-Gradle
plugin.

The moz.build data is now sufficient to, with some convolution, generate
the same compilation database that recursing the tree with the showbuild
target does.
The resulting code is not the prettiest, and exposes the shortcomings of
the current moz.build data model. It is however a first step towards
fixing those shortcomings, because they are now more clearly identified.
This was validated on all platforms on try by checking the output of
mach build-backend -b CompileDB -d -n
is empty when backing out the patch after running
mach build-backend -b CompileDB
once.
There are a few difficult directories to handle, with limited usefulness
compared to having the CompileDB properly filled for everything else
in a timely manner, so skip them for now.
This adds a substs field and cherrypicks the MOZ_ARTIFACT_BUILDS field so
we can determine whether or not an artifact build occurred.

Because the add-ons manager hasn't startup up yet we can replace the certificate
database in xpcshell tests with one that claims add-ons are signed by valid
certificates even when they aren't. This allows us to run tests even in builds
where signing cannot be disabled during for the normal application.
This adds an override for all tests except those that are explicitely testing
signing.

We have very few directories where we have SOURCES declared that are not
part of a library or program in some way. In fact, there is only one
where it is legitimate because we only use the object file
(build/unix/elfhack/inject). Others are the result of moz.build control
flow (see e.g. netwerk/standalone), and we end up building more objects
than we need to.
There are other cases where we need objects without actually linking
them anywhere, but there are other sources in the same directory, and a
corresponding Linkable is emitted. And in fact, the only case I knew
about (media/libvpx), doesn't use such objects since bug 1151175.
Since bug 1239217, artifacts builds are using a hybrid build system that
uses the fastermake rules to copy files to dist/bin, which means
artifact files are not removed by the processing of the dist/bin install
manifest. This means we don't need to add them to the recursivemake
install manifest anymore.
Currenlty --enable-artifact builds will take artifacts from fx-team regardless of the
state of the current working directory. This can lead to broken builds if someone
updates to a tree other than fx-team.
This commit changes the default behavior from tracking fx-team to finding all recent
pushheads and finding the closest to the working parent that has artifacts available.
This also fixes a mis-match between tree names according to mozext and branch names in
the taskcluster index preventing artifact download from common integration branches.

clang based tools typically choke when they encounter a lot of -XClang
arguments, and since those args are passed to the cc1 driver they're
unnecessary for such tools anyways.
This helps people who have things like --enable-clang-plugin in their
mozconfig use clang based tools without having to remove these arguments
manually.
Calling error() in moz.build files to indicate unsupported configurations is
useful, but readers using EmptyConfig will trigger them currently. This patch
allows a Config to have an `error_is_fatal` attribute, which will make
error emit a warning instead.

This is two straightforward optimizations in FileCopier: avoiding a redundant iteration
over the directory structure to find destination files (which includes a
call to normpath) and avoiding redundant calls to determine directories to preserve
when remove_unaccounted is not specified (which include a call to dirname).
Running a no-op install of _tests with this patch results in a reduction of about
25,000 calls to normpath and remove about 220,000 calls to dirname, resulting in
an overall speedup of 10-20%.
