It now handles adding .bp files and changing globs.
In order to do this, depfiles are now written separately from RunBlueprint.
This is necessary due to the confluence of a number of seemingly
unrelated factors:
1. The glob filelist dependencies are discovered in globSingleton
2. Singletons need to be registered because otherwise singleton module
types panic
3. Singletons don't work because they require mutators bp2build does not
run
Due to (1), we would need to run the glob singleton. However, due to (2)
and (3), we can't run singletons and have to run Blueprint with
StopBeforeGeneratingBuildActions, which is when the build actions
writing glob files would be generated. So what happens is:
1. When bp2build is run, the glob singleton is disabled
2. At the end of bp2build, the list of glob files is artifically added
to the depfile of the workspace marker file
3. When build.ninja is generated, the Ninja file containing the glob
list file is written by the now-active glob singleton
Test: Presubmits.

There is little overlap at this point, but we expect these to converge
more over time, to handle exported includes, libs, etc., this will allow
those changes to be handled in one place and allow more consolidation of
code.

go idiom is to define the interface where it is used rather than where
it is defined. This makes it obvious that ParseResult is not a used part
of the interface, removing the need to return an interface{} and cast
results.

This CL is pretty large, so I recommend starting with reading the newly
added tests for the expected behavior.
This change works in conjunction with the linked CLs in the Gerrit topic.
Those CLs add support for new platform() definitions for OS targets
specified in Soong's arch.go, which are configurable through
Android.bp's `target {}` property. It works similary to previous CLs
adding support for the `arch {}` property.
These configurable props are keyed by the OS: android, linux_bionic,
windows, and so on. They map to `select` statements in label list
attributes, which this CL enables for cc_library_headers' header_libs
and export_header_lib_headers props.
This enables //bionic/libc:libc_headers to be generated correctly, from:
cc_library_headers {
name: "libc_headers",
target: {
android: {
header_libs: ["libc_headers_arch"],
export_header_lib_headers: ["libc_headers_arch"],
},
linux_bionic: {
header_libs: ["libc_headers_arch"],
export_header_lib_headers: ["libc_headers_arch"],
},
},
// omitted props
}
to:
cc_library_headers(
name = "libc_headers",
deps = [] + select({
"//build/bazel/platforms/os:android": [

"//build/bazel/platforms/os:linux_bionic": [

This is a step in the right direction to allow generalized specification
of variant information in the form of configuration transitions, such
that not all transitions must be specified manually. This allows for
much more reasonable addition of new variations in mixed builds.

This requires linking Blueprint into soong_ui. It lets us avoid the
complicated dance of Ninja files and shell scripts: now the information
as to how soong_build is built is passed directly to Blueprint using a
struct that contains all the information the command line arguments used
to contain.
The ability to run Blueprint from the command line is kept (for now).
Some variables in bootstrap/command.go needed public accessor functions
because soong_build reads them. This will be disentangled by moving the
flag parsing to soong_build.
The presence of the flag definitions in Blueprint means that soong_ui
now also accepts them. This is not a problem in practice because they
are ignored and because soong_ui itself is hidden behind a few layers of
shell scripts.
Test: Presubmits + the new bootstrap_test.sh .

While this may be helpful in the immediate-term, it will cause
incredibly bloated logs as more of the build is managed by Bazel.

Previously, the build failed if the directory already existed,
so mixed builds had to be null builds.

This effectively moves execution of Bazel actions outside of soong_build
and alongside ninja execution of the actual ninja files, whether that be
by ninja or by Bazel itself.
This almost allows for mixed builds and Bazel-as-Ninja-executor to
coexist, but requires hacks explained in b/175307058.

Bazel is executed several times during the execution of soong_build.
For each bazel execution, generate a profile and save under the
BAZEL_METRICS_DIR which is defined in soong_ui.

Test: * USE_BAZEL_ANALYSIS=1 USE_BAZEL=1 m nothing and checked
if the cquery and graph build bazel profiles were generated.

to the local dev metrics pipeline.

This removes the need to source bazelenv.sh for USE_BAZEL_ANALYSIS, and
unifies mixed builds to use the checked in tools/bazel and bazelrc.
It also unifies all bazel-related output to be in out/bazel.
Without aosp/1502095, this change still requires toplevel_output_directories to be an empty
list, otherwise there'll be this error:
ERROR: Directories specified with toplevel_output_directories should be
ignored and can not be used as sources.

This adds an extra step to mixed builds: creating a master BUILD/bzl
file pair to facilitate running a single cquery command to analyze
all soong->bazel edges in a single request.

stderr is a bytes.Buffer, but the String() method has a pointer

With this change, bazel_module is a specifiable property on
genrule module definitions. With bazel-enabled mode, soong_build will
defer to Bazel for information on these modules.
