Without this, we throw UnrecognizedArgumentError when running commands
such as `./mach mochitest-plain test`, which causes an error message
such as the below to be emitted:
It looks like you passed an unrecognized argument into mach.
The mochitest-plain command does not accept the arguments: test
This patch will fix the above command to instead print the corresponding
deprecation message.

This implements a new "scan" mode for DMD that records the address
and contents of every live unsampled block in the DMD log. This
enables the low-level analysis of references from one block to
another, which can help leak investigations.
bf34d16b6ab2 added absolute_import to this file. When changed, "import
mozinfo" stopped picking up mozbuild.mozinfo and started importing
mozinfo instead.
Use relative imports to force mozbuild.mozinfo to be picked up.

This removes ambiguity as to which modules are being imported, making
import slightly faster as Python doesn't need to test so many
directories for file presence.
All files should already be using absolute imports because mach command
modules aren't imported to the package they belong to: they instead
belong to the "mach" package. So relative imports shouldn't have been
used.

DONTBUILD ON A CLOSED TREE: Android-only and the build changes are cosmetic.
Very much a first cut, but I'd like to get some Fennec early adopters testing.
This adds:
* |mach artifact install| to fetch and install Fennec binaries;
* |mach artifact last| to print details about what was last installed;
* |mach artifact {print,clear}-caches|, for debugging.
This code is exposed as a new mozbuild.artifacts Python but it's not
particularly general. My intention was to get things out of the mach command
more than produce a general artifact fetching API. We can leave that bike
shed to Bug 1124378.
I've been testing this with --disable-compile-environment and it works well
locally, although there's no reason a knowledgeable developer couldn't use
this in conjunction with a fully-built tree. (I don't know when such a
situation would arise, but I know of no technical impediment.)

Up to this point, mach command metadata has been stored in tuples.
Initially, things weren't so bad. But they have evolved into tuples with
many elements. Adding new attributes is cumbersome. Let's restructure
the code to capture metadata in a dedicated class.
Before, there existed a separate attribute on the @Command or
@SubCommand decorated method for each mach decorator: @Command,
@CommandArgument, @CommandArgumentGroup. With the magic of __ior__,
we can now capture all metadata on a single type. This simplies
processing, as we now only look at a single attribute on methods:
_mach_command.
Before, we used separate attributes to distinguish between mach commands
and mach sub-commands. Now that we have a type that can hold all data,
we combine things into the _mach_command attribute and look for the
presence of the "subcommand" attribute on this type to identify
sub-commands.

The hglib Mercurial finder was nice. But it is somewhat slow, as it
involves a separate Mercurial process.
This commit introduces a native Mercurial finder that speaks directly
to a Mercurial repository instance. It is significantly faster.
The new code is isolated to its own file because it imports Mercurial
code, which is GPL.

The moz.build reader uses absolute paths when referencing moz.build
files. *Finder classes expect paths to be relative to a base. When we
switched the reader to use *Finder instances for I/O, we simply provided
a default FileFinder based at the filesystem root. This was quick and
easy. Things worked.
Unfortunately, that solution isn't ideal because not all *Finder
instances can accept absolute paths like that. The
MercurialRevisionFinder is one of them.
Changing the moz.build reader to talk in terms of relative paths is a
lot of work. While this would be ideal, it is significantly easier to
defer the problem until later and hack up MercurialRevisionFinder to
accept absolute paths. This commit does exactly that.
Bug 1171069 has been filed to track converting BuildReader to relative
paths.

Now that moz.build files use finders for I/O, we can start reading
moz.build data from other sources.
Version control is essentially a filesystem. We implement a finder
that speaks to Mercurial to obtain file data. It is able to obtain
file data from a specific revision in the repository.
We use the hglib package (which uses the Mercurial command server) for
speaking with Mercurial. This adds overhead compared to consuming the
raw Mercurial APIs. However, it also avoids GPL side-effects of
importing Mercurial's Python modules.
Testing shows that performance is good but not great. A follow-up
commit will introduce a GPL licensed Mercurial finder. For now, get
the base functionality in place.

Sometimes moz.build data may not come from the local filesystem. To
support defining moz.build data in other backing stores, we switch
moz.build reading to use mozpack's *Finder classes for I/O.
The use of a FileFinder bound to / is sub-optimal. We should ideally
be creating a finder bound to topsrcdir. However, doing this would
require refactoring a lot of path handling in the reader, as that code
makes many assumptions that paths are absolute. This would be excellent
follow-up work.
While I was here, I cleaned up some linter warnings for unused imports.
On my machine, this commit results in a slight slowdown of moz.build
reading. Before, `mach build-backend` was consistently reporting 1.99s
for reading 2,572 moz.build files. After, it is consistently reporting
2.07s, an increase of 4%. This is likely due to a) function call
overhead b) the cost of instantiating a few thousand File instances
c) FileFinder performing an os.path.exists() before returning File
instances. I believe the regression is tolerable.

Passing raw file handles around is a bit dangerous because it could lead
to leaking file descriptors. Add a read() method that handles the simple
case of obtaining the full contents of a File instance.

Today, the *Finder classes are optimized for doing matching and
returning multiple results. However, sometimes only looking for a
single file is wanted.
This commit implements the "get" method on all the *Finder classes.
It returns a BaseFile or None.
FileFinder._find_file has been refactored into FileFinder.get
to avoid code duplication.

The current mode of execution of templates doesn't allow them to more advanced
control flow, like returning early, returning or yielding values, because that
mode of execution is equivalent to running the code at the top level of a .py
file.
Making the templates executed through a function call, although trickier,
allows those control flows, which will be useful for template as context
managers.
inspect.getsourcelines() and inspect.getfile() involve I/O out of our control.
Our use of those functions, however, doesn't require all their smarts. In fact,
we only use them on function objects, for which we can just do the work
ourselves without involving inspect functions that trigger I/O.
`mach help <command>` currently only displays a brief description of the
command along with its arguments. Sometimes more detailed help text is
needed.
With this commit, the docstrings of mach command handlers will appear in
the output of `mach help <command>` if they are defined.
I've implemented basic docstrings for the three flavors of mach commands
(normal command, main subcommand, subcommand) to demonstate things work.
My hope is others will start to fill in docstrings once this feature
lands so the output for `mach help` can serve as a better learning guide
for new contributors.

The old way of writing scripts for generated files would invoke the script thusly:
python script.py arg1...
Invoking the script this way means that the script's directory is
automatically added to sys.path, and importing modules from that
directory is easy. Let's make it equally easy in the new world for
GENERATED_FILES, too.
Document the role of l10n.ini, filter.py, file paths and checks.
Also add a glossary for the jargon used in the doc.
