This will allow a new kind of special variable where it is possible to do
FOO += ['bar']
All the current special variables are either strings (for which __setitem__ would
be called with a different string object), or a read-only dict (which doesn't
allow modifications).
We have many unit tests in the tree for some small parts of the build system
pipeline, but we don't have anything that resembles an end to end test, and we
kind of rely on the resulting Firefox not being broken by our changes.
With the Faster make backend growing, I want to ensure it produces the same
thing as the recursive make backend, at least for the parts it supports.
This adds some kind of test that allows to check that.
The test I'm about to add doesn't have XPIDL files, and that currently avoids
the FasterMake backend to run properly. Also, in the future, when the FasterMake
grows the ability to build C++ files, it should be possible to build Spidermonkey
with the FasterMake backend, but it doesn't have XPIDL files either.
This makes it clearer that really it's the same thing as FINAL_TARGET,
with preprocessing.
We still keep DIST_FILES in backend.mk because it's shorter and doesn't
really matter.
This new ChromeManifestEntry object type is generic and can hold any kind of
chrome manifest entry, but we currently only emit them for binary components.
References to sub-directory manifests is left to the backend, for now, until
all manifest entries are emitted by the frontend.
Ideally, we should properly make and shell quote everything we print out
in makefiles, but that's a can of worms I don't want to open just yet. So
I'll limit myself to just passthru variables.
This further improves the changes from bug 1224460 to e.g. handle variable
references mixed with text, and to avoid adding empty strings to the
resulting flags variables when the expansion leads to an empty string.
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.
FlatFormatter, JarFormatter and OmniJarFormatter all, in some way, deal
with different pieces of the package being handled differently.
Instead of each of them dealing with their different pieces in some subtly
different way, instead, introduce a new base package formatter class that
will handle it for all of them.
Use this new PiecemealFormatter for the FlatFormatter.
Only directories containing chrome manifests are given as base to formatters,
but there can still be files given outside the bases, like, on mac builds,
all files in Content/MacOS, or Content/Info.plist, whereas chrome manifests
are under Content/Resources.
There is a lot of repetition across its various tests, and we're going to add
some more in a subsequent change, so it is desirable to make it a less
repetitive task.
This function was found to be a little slow while profiling due to repeated calls to
mozpath.dirname. This patch speeds up the function replacing dirname with string manipulation
(these paths are already normalized), by caching results on the basis of directory,
and converting from iteration to recursion to increase use of the cache.
This commit speeds up the "install tests" step run as a part of the build and running
tests by ~10% on a fast linux laptop.

When a make target is generated with FileAvoidWrite, this can cause targets to
get rebuilt perpetually when a prerequisite is updated, because FileAvoidWrite
will leave the target's mtime older than the prerequisite's when the target's

Calling CommonBackend.consume_object ensures that we process WebIDL and
IPDL files (and many other things) correctly. Calling
CommonBackend.consume_finished ensures that the CompileDB backend gets
to see the unified bindings and protocol files that we generate, and add
those files to the compilation database.
The only thing we need the obj for here is getting the objdir. Future
patches will just have an objdir when calling this function, and not a
proper mozbuild object. In light of these facts, let's change the
function to accept an objdir only, which will make those future patches
easier.
For GENERATED_FILES scripts that want to report dependencies, this
change makes it easy to use |preprocess|, rather than having to
construct and use |Preprocessor| manually.
In addition to their inputs declared in moz.build files, generated files
may also depend on other files, such as #includes in preprocessed files.
Let's provide a place for file_generate.py to write out those extra
dependencies.
Indicating a jar currently looks like the following in a jar manifest:
path/to/name.jar:
The `path/to` doesn't contain the implicit "chrome/" directory. This, in
turn, doesn't allow much flexibility to use the jar maker for what is not
necessarily under chrome/.
To use the jar maker to fill some chrome manifest for the default theme
extension, we currently use a hackish path to get to the right location,
and rely on the chrome.manifest file in the parent directory never to be
picked by the package manifest, which is a quite horrible way to do this,
but worked well enough for that specific use case.
With the need to handle system addons at the build system level, it
becomes necessary to come up with something less hackish.
What this change introduces is an additional syntax for the jar manifest,
in the following form:
[base/path] sub/path/to/name.jar:
Using this syntax, there is no implicit 'chrome' path. The `base/path` is
relative to the current DIST_SUBDIR, and the `sub/path` is relative to that
`base/path`. The distinction can be useful for build system backends.
The assumption that the "root" chrome.manifest is in the parent directory
of the implicit "chrome" directory dies, and the `base/path` is where the
root chrome.manifest is placed.

for unclear reasons (and the lack of bug number doesn't help), and hasn't been
used, as far as I can see in the gecko-dev history, other than in bug 206029,
which is the only use currently in the tree.
Bug 206029 was working around the Flash player installer modifying Firefox's
prefs file and not dealing with it properly or something depending on the line
endings. 11 years later, all prefs files except channel-prefs.js are in
omni.ja, so obviously, bug 206029 doesn't actually apply anymore.
So, let's simplify it all and get rid of this.
Compressing C++ unit tests is a long pole when writing test archives.
Experimenting with various levels of compression revealed that
compression level 9 was providing minimal space savings for
significantly longer archiving times and greater CPU usage.
Results of our experimentation of `make -sj8 package-tests` on OS X
with various levels of compression are below. Note: these numbers were
accidentally obtained without JS tests being archived. This skews the
results a little but doesn't impact the analysis below.

Levels lower than 3 resulted in larger archives with no decreae in
wall time and marginal decrease in CPU time.
As we can see, lowering the compression level reduces archiving time by
>3x while only increasing total archive size by ~2.5 MB or ~1% for
compression level 5.
Total time hits a plateau around levels 4 and 5. After that, file size
increases faster for little decrease in wall time. I suspect that we're
hitting Python limits from having to process thousands of files: there's
only so fast Python can do I/O and make function calls.
I think choosing 4 or 5 for the new compression level are acceptable.
I went with 5 because the wall time savings from 5 to 4 are marginal and
the archive size does start to increase a bit faster at 4. That being
said, 4 does consume 10% less CPU. I could easily just 4 as well. 5 is
more conservative. We can always change to 4 after seeing results in the
wild.
The end result of this change is `make package-tests` is much faster:
Before: 228,146,761 bytes; 31.2s wall; 75.9s CPU
After: 230,725,600 bytes; 11.4s wall; 45.0s CPU
Delta: +2,578,839 bytes; -19.8s wall; -30.9s CPU
When you take the whole series into consideration:
Before: 44.2s wall; 84.6s CPU
After: 11.4s wall; 45.0s CPU
Lowering CPU is impressive considering we switched from the C `zip`
implementation to Python!
Keep in mind we were at ~78s wall before e87b74b3db43 introduced
concurrent archive generation!
And we still haven't eliminated the staging of JS tests, which are
several thousand files and a few dozen MB!

Metrics are nice. Adding this output clearly demonstrates that C++ unit
tests are the long pole by far: they take ~95% of wall execution time
to archive (~30s total). The next longest archive only takes ~11s to
produce. This will be important if we ever want to reduce archive time
further on optimal hardware.
FWIW, disabling compression will produce a C++ unit test archive in
1.0s. Archives with more files take longer, despite the significantly
smaller sizes.

Won't impact performance much. But fewer make foo makes porting the C++
unit tests (which are the largest remaining tests) to the Python
archiver easier to grok.
This conversion did change behavior slightly. Previously, startup
cache files weren't being packaged if startup cache was disabled. Now,
we always package them since their presence in the test archive should
be harmless. The original change to guard their inclusion in
ee82e0ae5488 was probably unnecessary.

This is slightly more involved than earlier changes because reftests
have a one-off mechanism for finding files. Essentially, the master
reftest manifest is loaded, directories are discovered, and every file
in those directories is packaged.
We add support to our test archive generation tool to read sources from
reftest manifests and tell it where the reftest manifests are.
print-manifest-dirs.py was only being used for staging reftest files.
Since we don't do that any more, the functionality doesn't need to exist
in a standalone file, so it has been moved inline into test_archive.py.
This change avoids copying ~26,000 tests consuming 131 MB during test
packaging. This is a majority of the file count that was remaining in
the stage directory at this point. On my machine (which hasn't typically
seen major wall time wins from not staging files due to its fast SSD),
this change made test packaging ~20% faster, reducing wall time from
~50s to ~40s!
A Try push seemed to indicate drastic results with the series up to this
point. Including the already landed changes to generate test archives
concurrently, test packaging times on OS X builders dropped from ~18:40
to 6:29! Times on Linux x64 remained about the same (~2:46). This is
possibly due to these machines already having SSDs and due to normal
variance in performance of builders and EC2 instances.

Test archive generation currently copies a bunch of files into a staging
area then runs `zip` to produce ZIP files. There are 2 concerns with
this approach:
1) We incur a lot of extra I/O to copy files so everything is
rooted in a single tree so the `zip` invocation and paths are
simple.
2) ZIP files inherit properties from the local filesystem (including
mtime), making ZIP files non-deterministic.
This commit introduces a new mozbuild action for producing test
archives. It does so using the mozpack file finder and JAR writer,
which are used throughout the build to deterministically
produce ZIP/JAR files from files in multiple source directories.
We implement support for producing the mozharness archive. This archive
does not involve files that are staged, so no I/O is saved. In fact,
the switch from `zip` to Python likely makes this slightly slower.
However, we do have deterministic archives now.
Additional archives will be ported over in subsequent commits.

The flags added in toolkit/locales/Makefile.in turn out not to be actually
used, so just remove that.
The remaining uses of XULPPFLAGS are to set debug flags depending on whether
MOZ_DEBUG is set or not. Just set a dedicated variable with the right value
from configure.
When running mach `build-backend` or `config.status`, it is now possible to
pass multiple backends to the --backend/-b option, so that they can share
moz.build reading and object emitting.
The command line syntax is however maybe a little awkward:
mach build-backend -b Backend1 Backend2
but supporting with `-b Backend1 -b Backend2` requires more argument parser
twiddling (action='append' doesn't work out of the box with choices, we'd
need a custom action class)
Currently, we set a flag on each object to know whether it has been consumed
by the backend. This doesn't work nicely when multiple backends try to consume
the same objects.
- Make all backends report the time spent in their own execution
- Change how the data is collected for the reader and emitter such that
each of them is aware of its own data, instead of everything being
tracked by the backend.
This is meant to open the door to multiple backends running from the
same execution of config.status.
This commit exposes test-deps file info as a mach command, and
modifies the test scheme reader to make it filter out unsuitable
contexts when generating TestManifest objects for metadata context.

This gets us a limited version of AAR support: we can consume static
AAR libraries, where here static does not refer to linking, but to
static assets that are fixed at build-backend time and not modified
(or produced) during the build. This lets us pin our dependencies
(and move to Google's versioned Maven repository packages, away from
Google's unversioned ad-hoc packages).
By restricting to static AAR libraries, we avoid having to handle
truly complicated dependency trees, as changing parts of generated AAR
files require delicate rebuilding of the APKs (and internal libraries)
that depend on the AAR files.
It is possible that we will generate AARs in the tree at some time.
Right now, we don't do that, even for GeckoView: the AARs produced are
assembled as artifacts at package time and are intended for external
consumption. We might want this for GeckoView and Fennec at some
time; we should consider using Gradle everywhere at that point.
The patch itself does the simplest possible thing (which has precedent
from Gradle and other build systems): it simply "explodes" the AAR
into the object directory and uses existing mechanisms to refer to the
exploded pieces.
AARs have both required and optional components. Each component is
defined with an expected and required flag. If a component is expected
and not present, or not expected and is present, an error is raised.
If the component is expected and present, autoconf's ifelse() macro is
used to define the relevant AAR_* component variables. If the
component is not expected and not present, no action is taken. A
consuming build backend therefore can guard all AAR_* component
variables with just the top-level AAR variable.
Many AAR files have empty assets/ directories. This patch doesn't
explode empty assets/ directories, protecting against trivial changes
to AAR files that don't impact the build.
There's a lot not to like in this approach, including:
* We need to manually reference internal AAR libs;
* I haven't separated the pinned version numbers out of configure.in.
However, it's closer to what we want than what we have!

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.
Previously, we used a PPA on Ubuntu to install Mercurial. The PPA has
proved to be unreliable. Furthermore, we didn't have a mechanism for
installing a modern Mercurial on Debian and other derived distros.
In this commit, we remove the PPA from Ubuntu. We add the ability to
install Mercurial from pip to the Debian bootstrapper. However, since
some people may not want <not apt> installing package-like things,
we add a prompt explaining the situation and giving users a choice.
We recommend installing a modern Mercurial via pip. But we also given
the option to install a likely legacy version via apt. And, for Git
users, we give the option to not install Mercurial at all.
Since the new version of the Ubuntu bootstrapper is empty, it doesn't
need to exist, so it has been removed.

Android version codes serve multiple masters. They indicate newer
versions, yes; but they also break ties between versions with
different features and requirements. High order bits effectively
partition the space of versions and are valuable. Since Android
version codes are signed Java integers, we have 31 bits to work with.
Mozilla's traditional build ID is YYYYMMDDhhmmss. This was chopped to
ten characters (YYYYMMDDhh, i.e., hourly build IDs) and then converted
to a decimal. This took many high order bits. We will lose another
high order bit in the 36th month of 2015 -- i.e., as soon as the year
rolls over to 2016. If we waited to lose the next higher order bit,
we'd lose that one in the 46th month of 2017 -- i.e., as soon as the
year rolls over to 2018.
The following patch sacrifices a high order bit to change the version
scheme, winning us roughly 15 years of hourly build IDs before we are
forced to lose another high order bit. So it's clearly to our
advantage to change the scheme sooner rather than later -- we will
sacrifice 1 bit for 15 years of build IDs, rather than keeping the
current scheme and sacrificing (say) 2 bits for 3 years of build IDs.
The resulting scheme produces build IDs that look like (in binary):
0111 1000 0010 tttt tttt tttt tttt txpg
The meaning of these build IDs is documented in the Python source code
that generates them.

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.

This moves a little bit more of mobile/android/base/Makefile.in into
moz.build, and gets closer to moving that aapt invocation into
java-build.mk.
There are no other extra package consumers in the tree. (There should
be a new one shortly: b2gdroid.)

This paves the way for defining additional Android packages in
moz.build, which is a step toward moving the special
mobile/android/base/Makefile.in aapt invocations into the generic
java-build.mk framework.
The new variables are both passthru variables for now: in the future,
we'll roll them into some aggregate Android APK definition.
It's worth noting that references to the variables in Makefile.in
files are only defined after including rules.mk (and thereby
backend.mk). This only required a few changes in the tree but it
confused me for some time.

This change adds a 'what' parameter to |mach clobber| which facilitates clobbering other things as well.
E.g, |mach clobber python| now clobbers all .pyc and .pyo files in the tree. Multiple clobber targets can
be specified, e.g |mach clobber objdir python|. By default |mach clobber| without arguments will only
remove the currently active objdir, the same as before.

We have had singular ANDROID_ASSETS_DIR in Makefile.in for a while.
Fennec itself does not use the existing Makefile.in Android code, for
complicated historical reasons.
This makes the existing variable moz.build-only; generalizes the
existing variable to an ordered list; and adds the equivalent use of
the new list to the Fennec build, with a simple example asset.
This patch also updates the packager to include assets packed into the
gecko.ap_. Without the packager change, the assets/ directory in the
ap_ gets left out of the final apk. This whole approach is totally
non-standard but is more or less required to support our single-locale
repack scheme.

This patch does a few things. First, it adds an AbsolutePath data
type, sibling to SourcePath and ObjDirPath. (Existing Path consumers
that accept an open set of Path subtypes, and that only use full_path,
should function fine with the new AbsolutePath subtype.)
Second, it moves ANDROID_RES_DIRS to a moz.build list of Paths
(ordered). We test, but don't use in tree, the new AbsolutePath.

It is useful to be able, during mozconfig execution, to do tests depending
on what was previously added with mk_add_options. Specifically, there is a
need to do this for MOZ_PGO because developers pushing to try may add it to
mozconfig.common.override.
While, ideally, it would be nice if we just defined the variable itself in
the mozconfig execution environment, that is a tedious task, having to jump
through hoops with eval, and handle all cases of variable assigment properly.
The hacky alternative is to just treat MOZ_PGO specially, but meh.
So instead, we set a ${var}_IS_SET variable to 1, indicating that a
mk_add_options defined ${var} to some value.
Bug 1153566 changed the regexp used in that method in such a way that there
has been a big hit in the time spent executing the make backend. On my machine,
with the current code, mach build-backend indicates:
Backend executed in 5.01s
With the change from bug 1153566 reverted:
Backend executed in 2.97s
That's a significant regression for a 4-character change.
But we can actually avoid using regexp in most cases, which can make things faster
than they were. With this change, we get down to:
Backend executed in 2.28s
For reference, making the _check_blacklisted_variables method do nothing at all
ends with:
Backend executed in 2.20s

This just allows a little versatility for consumers such as b2gdroid,
which are Fennec-like but don't have MOZ_APP_NAME=fennec.
I elected to pass appname as a parameter rather than modify the
existing distdir because I expect to want to differentiate, in some
way, the output AAR files based on the underlying name. That is, in
future we might generate geckoview-fennec-VERSION.aar and
geckolibs-b2gdroid-VERSION.aar, or stuff the name into the Ivy version
information, or...
This also fixes a typo in one of the JarFinder instantiations.

CalledProcessError.output and subprocess.check_output's return value
are str types. This file uses unicode_literals. If we do something
like `if 'foo' in e.output`, there will be a mix of str and unicode
types and Python will do implicit conversion. If the strings aren't
ASCII, we'll likely encounter a UnicodeDecodeError.
Use b'' literals around all strings to prevent this coercion from
occurring.
