Now that defining $DMD is no longer necessary to run DMD, this patch does the
following.
- Removes all the places where we set DMD=1 (test harnesses, etc.)
- Still handles DMD=1, for backwards compatibility.
- Prints "$DMD is undefined" at DMD start-up if appropriate.
- Writes a |null| value for |dmdEnvVar| in the JSON if $DMD is undefined. Bumps
the DMD output version number accordingly.
- Changes a bunch of the test files accordingly, including changing the mode of
script-ignore-alloc-fns.json in order to test a case where $DMD is undefined.

FileCopier.copy() was performing a lot of os.path.normpath() operations.
Profiling revealed that os.path.normpath() was the function with the
most wall time CPU usage when processing the tests manifests. Upon
subsequent examination of the code in question, all the paths being used
were already normalized. So, os.path.normpath() wasn't accomplishing
anything.
This patch results in ~300ms reduction in wall time to process the tests
install manifest on a fully populated page cache. Execution time drops
from ~2.8s to ~2.5s.
Profiling reveals that after this patch os.stat() is the #1 wall time
consumer. However, os.path.{join,dirname,normpath} still account for
~1.5x the wall time of os.stat(). There is still room to optimize
this function.

This patch moves profiling mode selection from post-processing (in dmd.py) to
DMD start-up. This will make it easier to add new kinds of profiling, such as
cumulative heap profiling.
Specifically:
- There's a new --mode option. |LiveWithReports| is the default, as it is
currently.
- dmd.py's --ignore-reports option is gone.
- There's a new |mode| field in the JSON output.
- Reports-related operations are now no-ops if DMD isn't in LiveWithReports
mode.
- Diffs are only allowed for output files that have the same mode.
- A new function ResetEverything() replaces the SetSampleBelowSize() and
ClearBlocks(), which were used by the test to change DMD options.
- The tests in SmokeDMD.cpp are split up so they can be run multiple times, in
different modes. The exact combinations of tests and modes has been changed a
bit.

People often seek to learn how mach commands work. A common way to do
this is to launch a debugger and step through the code as it is
executing. But this requires someone to first find and modify the mach
command. This involves overhead.
This patch adds a global --debug-command argument to mach. When present,
we launch an interactive debugger right before command dispatch. This
allows people to easily enter a debugger to see what mach commands are
doing, hopefully lowering the barrier to understanding and contributing.

JS module installation performs simple file copying or preprocessing.
There is no reason it can't occur in parallel. Move it to the misc tier.
As part of this, I recognized that TESTING_JS_MODULES was assigned to a

belong to any tier. So the tier is now listed as None.

The build system being what it currently is, there are various cases where one
wants something explicit, rather than the current autodetection.
For instance, one may want to run
make -C $objdir chrome
instead of
make -C $objdir/chrome
that mach build chrome currently invokes.
There are several such usecases that mach's autodetection makes harder, and
it's sometimes awkward when telling people, to debug their issues, to run
make -C objdir something
and hear back that objdir doesn't exist or something along those lines,
because they took "objdir" literally.
There are, sadly, many combinations of linkage in use throughout the tree.
The main differentiator, though, is between program/libraries related to
Gecko or not. Kind of. Some need mozglue, some don't. Some need dependent
linkage, some standalone.
Anyways, these new templates remove the need to manually define the
right dependencies against xpcomglue, nspr, mozalloc and mozglue
in most cases.
Places that build programs and were resetting MOZ_GLUE_PROGRAM_LDFLAGS
or that build libraries and were resetting MOZ_GLUE_LDFLAGS can now
just not use those Gecko-specific templates.
It's not entirely clear passing down all the metadata makes sense. On the
other hand, when creating the template execution sandbox, passing down
exports does assign the value for the exported variable in that execution
context. When that context is merged with the caller sandbox context, the
exported variable is reassigned, even if the value is not modified. Then,
if the caller sandbox itself reassigns the exported variable, it fails
because calling a template already did it once, unexpectedly.
Not passing down exported variables makes the template execution sandbox
never set those exported variables, so that they are not merged back. The
caller sandbox can then properly reassign the exported variable.
The in-tree Sphinx docs have been broken since bug 1041941 because
processing moz.build files outside their context doesn't work.
Specifically, templates aren't loaded (because this information usually
comes from a parent moz.build file). A new execution mode is needed.
I tried to implement a proper execution mode. However, I kept running
into walls. While we should strive for a proper execution mode, this can
be a follow-up, tracked in bug 1058359.
This patch implements extraction of Sphinx variables from ast walking.
It is extremely low-level and definitely a one-off. But it solves the
problem at hand: |mach build-docs| will work after this patch is
applied.

The reason to use '+' prefixing was to distinguish between options to the
mach command itself, and options that are passed down to whatever the
command does (like mach run passing down args to the built application).
That makes things unnecessarily awkward, and quite non-standard.
Instead, use standard '-' prefixing, and pass all the unknown arguments
down. If there is overlap between the known arguments and arguments supported
by the underlying tool (like -remote when using mach run), it is possible to
use '--' to mark all following arguments as being targetted at the underlying
tool.
For instance:
mach run -- -remote something
would run
firefox -remote something
while
mach run -remote something
would run
firefox something
As allow_all_arguments is redundant with the presence of a argparse.REMAINDER
CommandArgument, allow_all_arguments is removed. The only mach command with a
argparse.REMAINDER CommandArgument without allow_all_arguments was "mach dmd",
and it did so because it didn't want to use '+' prefixes.
These manifests are special in that they don't package their test files
into the test package. Each test listed in an instrumentation manifest
serves as an identifier rather than a file.

Up to now, DIRS and TEST_DIRS were dumb values. This change makes them
a list of ContextDerivedValues, and handles the fact that some types of
paths are relative to the current source directory and others to the
topsrcdir.
This also makes us one step closer to fixing bug 991983.
After bug 762358 mk_add_options MOZ_MAKE_FLAGS was simply ignored in client.mk
processing. At the same time, mach environment was expecting a list of options
while the mozconfig reader returned a single string, so straighten this up at
the same time.
Having to walk over elements and strings of HierarchicalStringList with
an external recursive function is un-Pythonic and adds unnecessary
obfuscation to several tasks. Add a walk() function to
HierarchicalStringList, modeled on os.walk(), to handle these cases more
directly.
The forward slash appears to be the standard path separator in zip/JAR
files. Accept back slashes when adding paths to a JAR.

The install manifest processor starts with an empty InstallManifest and
uses |= to "concatenate" instances. It became pretty obvious when
developing some patches that add more preprocessed files to install
manifests that the source install manifest dependency was getting
lost during the |= operation. This patch fixes it.
The solution is not ideal performance wise. But slightly worse
performance (only after config.status, however) is better than
clobbers.
A test has been added to ensure this doesn't regress.

- parent and var were used for TOOL_DIRS/TEST_TOOL_DIRS, which were removed in
bug 1043802.
- tier metadata was not really used, and tiers are going to go away soon
anyways.
As handled in configure.in, EXTERNAL_SOURCE_DIR is a single directory for
external sources, and more specifically, comm-central. There is no need
to handle it as a list in the moz.build emitter.
At the same time, avoid checking the external sources for every moz.build,
and bind it to a config environment.
As a special exception, we change List's + and += operators to treat
"+ None" and "+= None" as "+ []" and "+= []" respectively.
This is a hack to make moz.build files simpler so they don't have to
perform "is x" checks before appending x.
While I was here, I fixed the implementation of List.__add__ to return a
List instead of list.

This patch makes EXTRA_{PP_,}JS_MODULES similar in functionality to
TESTING_JS_MODULES: we indicate the path relative to
$(FINAL_TARGET)/modules with an appropriate hierarchy of paths.
We're going to build on top of INSTALL_TARGETS for the next patch, and
it's easiest to do so if we can look at the 'directories' in the
hierarchy, rather than the individual strings.
I am slightly surprised that we haven't needed this before, but the
motivating idea behind this is wanting to do:
VARIABLE.with.some["non-pythonic-identifier"] += ...
It seems unfortunate that the behavior is completely overridden by
subclasses, but I don't see a good way around that.
Straight assignments to HierarchicalStringList, which we'll change
EXTRA_JS_MODULES to in a later patch, don't work. This change, in
addition to making things work as expected later on, also is more
consistent with existing practice.
While most environments are using the root topobjdir, some can be using a
different path. This happens for comm-central files. For those, the compile
target needs to have paths relative to the root topobjdir instead of relative
to the comm-central topobjdir.
As a first step, this moves PYTHON_UNIT_TESTS to moz.build as a passthru
variable. In the future, we could hook it up to |mach test|.
The __init__.py files may not need to be in the list, but I don't want to
change the list here.
While I was here, I removed the try..except in favor of failing fast.
Before, we were only making cosmetic changes. Now, we actually need the
group for mach to work. It makes sense to stop ignoring errors.

Some moz.build syntax errors cause the thrown SyntaxError object to not include
an offset field, leading to all sorts of hilarity when we try printing messages
depending on SyntaxError.offset. Check for this case and simply don't print
the caret if so.
We want to make it turnkey for people to use reviewboard. So, we add
reviewboard and related functionality to |mach mercurial-setup|.
Since the reviewboard extension only works in Mercurial 3.0 and newer,
we add some version detection for the Mercurial version. This should
have been done months ago. We now have it.
I also took the opportunity to inform |mach bootstrap| that Mercurial
2.x is no longer modern.
I also updated the messaging around mq to encourage fewer new users to
use it. You may find this controversial. People can always ignore the
message.
Finally, I also added a histedit prompt to the mix, since a lot of
people don't know about that and many find it useful.

This adds a format option to mach environment and uses it in client.mk to
create a .mozconfig.json in the objdir, containing all the relevant data
from mozconfig. If the mozconfig doesn't change in a way that alters that
data, we still skip configure.
At the same time, use mach environment in place of mozconfig2configure and
mozconfig2client-mk, which makes us now have only one mozconfig reader.
Also, in the mozconfig reader, keep track of environment variables (as
opposed to shell variables), so that changes such as a variable that was
exported not being exported anymore is spotted. At the opposite, in order
for irrelevant environment variable changes not to incur in re-running
configure, only a set of environment variables are stored when they are
unmodified. Otherwise, changes such as using a different terminal window,
or even rebooting, would trigger reconfigures.
Finally, make mach environment emit both MOZ_OBJDIR and OBJDIR for
client.mk, and cleanup some objdir-related things in client.mk..
At the same time, make the mozconfig reader take MOZ_OBJDIR from the
environment if it is defined there and not in the mozconfig.
