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.
Mach has special handling for remainder arguments which previously
only worked with the decoration form. Extend this to also work when
a command passes in an explict parser
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.
Move Python code into an xpidl subdirectory, and include a setup.py to allow
inclusion from pip install or requirements files. Change build directory
variables appropriately.
I considered three ways to do this:
* one, as a Python script executed with $(shell);
* two, as a Python script that writes an include file for the preprocessor;
* three, as a function exposed to the moz.build sandbox.
I rejected two because it's both tied to the preprocessor, and awkward
to make handle the dependency on the buildid (in a file) and
additional build defines (in config.status).
I rejected three because I know of no precedent for this approach, and
it hides the dependency on the buildid.
One doesn't handle failures in the script gracefully, but neither did
the existing approach. This patch is at least testable.
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.
DONTBUILD NPOTB
This was just an oversight during the initial landing, leading to two
copies of artifact libraries being appended to the same destination
file.
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.
