ccf36aa928 LOG_DIR changes should not trigger soong_build to re-run
On the build servers, LOG_DIR is a subset of DIST_DIR, which encodes the
build number. This means that LOG_DIR is guaranteed to be different for
every build, and we'll never re-use previous soong runs on CI builds.

The current use case (writing out soong metrics) shouldn't care if the
value changes, so pipe the environment variable through, bypassing the
env dep checks. It's not clear if this is the only issue triggering
soong_build re-runs on the build servers, but it's a start.

Test: Change DIST_DIR, soong_build does not re-run.

027881cf35 Add extraNinjaDeps to mixed builds depfile
This was accidentally removed in aosp/2094705. Among other possible
issues, this caused the "used environment variable" file to be omitted
from the depfile of soong_build during mixed builds, which would result
in soong_build not being subsequently retriggered during env var
changes.

Sendng this out as a quickfix, regression test to follow.

Bug: 233774464
Test: Manual `m nothing && USE_BAZEL_ANALYSIS=1 m nothing && m nothing`,

f874e46153 Refactor mixed builds to only take one pass
This large refactoring has both immense performance implications and
improves mixed builds complexity / usability. Summary:

1. Queueing calls to Bazel is done in a new mutator instead of a full
   soong_build pass. Normal soong_build flow is interrupted (via a
   functional hook in blueprint) to invoke bazel and parse its response.
2. Implementing mixed build support for additional modules is as simple
   as implementing MixedBuildsBuildable. In this interface, define the
   request that must be queued to Bazel, and then subsequently define
   how to handle the returned bazel cquery metadata.
3. Mixed builds consists of only a single pass. This greatly
   improves mixed build performance.

Result:
  A 33% runtime improvement on soong analysis phase with mixed builds.

Caveats:
  C++ BazelHandler handling still remains a bit of a mess; I did what
  I could within this CL's scope, but this may require additional cleanup.

Test: Treehugger
Test: Verified that aosp_arm ninja file is bit-for-bit identical with or
without this change.

eb0454b2a4 Generate actions when building the module graph.
This is necessary because GenerateAndroidBuildActions() is effectively a
mutator and therefore can change the data stored in each module.
Sometimes one wants to dump that data in the JSON module graph, and in
order to do so, actions need to be generated.

I briefly entertained removing StopBeforePrepareBuildActions(), but it
incurs a 10-second penalty on "m soong_docs" and "m bp2build" so I
decided to keep it.

66213a64b2 Disable protobuf deterministic randomness in soong_build
Soong writes out text protos for the sbox manifests, and if those change
every time soong changes, we trigger rebuilds of significant portions of
the tree. This is very annoying when attempting to iterate on Soong, so
disable this functionality at the soong_build level.

89fcdcb788 Refactor the creation of soong_build calls.
They were a bit repetitive.

In addition, make the environment checks more correct; they could
probably use an integration test or two to make sure that when the
environment changes, exactly those outputs are rebuilt that need to be,
but for now, this is an improvement already.

c6012f36e1 Invoke soong_docs from the bootstrap Ninja file.
This makes soong_ui the only place where soong_build is invoked, thus
greatly simplifying the conceptual model of the build.

It comes with the slight limitation that now soong_docs (and queryview
and the JSON module graph) are not Make targets anymore, but I suppose
that's an acceptable loss.

The only place where someone depended on soong_docs from a Makefile is
removed in a separate change.

e571dc3bd0 Print the JSON module graph correctly.
Before, we piggybacked on the implementation of regular soong_build and
wrote a fake build.ninja file to satisfy Ninja.

Now, instead, the JSON module graph is a a separate action in the Ninja
output file. This has the pleasant side effect that one can flip back
and forth between generating the JSON file and regular Soong without
loss of incrementality.

Side cleanup: write .d files in a slightly cleaner way.

809d2ed548 Do globbing-related paperwork explicitly.
In particular, the writing of build-globs.ninja and the collection of
glob list files for build.ninja.d is now done outside of the Blueprint
invocation.

This is useful because RunBlueprint() is sometimes called multiple times
in a single soong_build invocation and because now glob processing is
not hidden by the machinery of Blueprint.

They used to be defined in Blueprint but since it doesn't have a
separate existence anymore, we can consolidate all command line

by a simple Go function call and not by invoking a separate binary, so
command line arguments are not needed there.

56ebaf35b3 Separate the files of bp2build and soong_build.
The following files are forked:

- build-globs.ninja
- The glob list files
- .d files for the glob list files
- The output file (build.ninja or the bp2build marker file)

This makes bp2build and soong_build not overwrite each other's files
they need for proper incrementality.

53dfa408b4 Generate build-globs.ninja when running bp2build.
This fixes null bp2build builds.

When running bp2build, out/soong/.bootstrap/build-globs.ninja wasn't
generated, therefore none of the globs in out/soong/.primary/globs have
actions to generate them. This makes bp2build always re-run on a null
build, because it depends on those non-existent globs in its depfile.

Fix the above by generating a build-globs.ninja file with the globs that
bp2build encounters during conversion, and add tests to verify that null
builds and bp2build -> soong workflows correctly regenerates the
build-globs.ninja file.

Test: soong integration tests for null soong->soong, bp2build->bp2build and bp2build->soong builds.

4fabaf52b0 bp2build/b: exit early in GENERATE_BAZEL_FILES=1.
This CL fixes a typo in writeFakeNinjaFile to correctly write
a fake out/soong/build.ninja and its depfile. It also modifies bootstrap
phase to *not* run the main soong build phase (which takes more than a
minute) if GENERATE_BAZEL_FILES=1.

This change has the side effect that `GENERATE_BAZEL_FILES=1 m nothing`
no longer generates the real build.ninja, which is fine because one
shouldn't be using GENERATE_BAZEL_FILES=1 for that anyway (or, use
USE_BAZEL_ANALYSIS=1). This change has no effect on mixed builds.

Time on a change to Soong or any Android.bp files:

Before: bp2build_workspace_marker (~20 seconds) + build.ninja (1 min)
After: bp2build_workspace_marker (~20 seconds)

d518e1a407 Make bp2build be more correct.
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

f8e2428c5d Allow running bp2build as part of a regular build.
This is done by setting the INTEGRATED_BP2BUILD environment variable
when invoking the build.

Even though the name of the marker file insinuates that a Bazel
workspace is already created, this is not the case yet.

An issue that remains is that a .d file is not written for the marker
file so it won't be rebuilt if a .bp file changes. Fixing this requires
delicate surgery because writing the .d file is the result of delicate
interplay between Soong and Blueprint.

There are also a number of semi-related fixes:

- The name of soong.environment.{used,available} is now on the command
  line of soong_build (soong_docs is still special cased because its
  command line in the Ninja file is taken from the os.Args of
  soong_build so it's not trivial to remove the --{available,used}_env
  from it
- bp2build writes a separate soong.environment.used file
- I had to call SetAllowMissingDependencies() separately when creating
  the android.Context for bp2build so that bp2build runs in the
  integration tests (it was not obvious how not to do this)
- Fixed a number of integration tests where a command with an expected
  exit code of 1 was used as the last one in a test case, thereby
  breaking the test suite

f0b3b94bb3 Make GENERATE_BAZEL_FILES=true correct.
This is achieved by writing soong.environment.used in Main() instead of
as a side effect of a singleton. This makes a difference because build
actions are not generated when GENERATE_BAZEL_FILES=true is set,
therefore the side effect did not happen.

Arguably, Main() is made worse by this change, but I don't want to
tackle the problem of readably determining which mode soong_build is
running in in this change.

Test: Presubmits + the additional test.

d1e3f1ff08 Embed minibp into soong_ui.
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 .

164e0867fc bp2build: add a simple UI to report migration progress.
Sample output:

[bp2build] cc_library_headers: 5 targets
[bp2build] cc_object: 5 targets
[bp2build] filegroup: 4 targets
[bp2build] genrule: 4 targets
[bp2build] sh_binary: 1 targets
[bp2build] Generated 19 total BUILD targets from 39270 Android.bp modules.

This CL adds an additional CodegenMetrics return value to
GenerateBazelTargets calls, which are called from bp2build, queryview,
and their tests. For this UI, we only want to use it for bp2build, and
not queryview or tests, since it's not useful for the former, and can
pollute the CLI for the latter.

7dcc4fcc68 bp2build: fix BUILD file generation incrementality bug.
Before this change, changes to any Android.bp file would not trigger a re-run of bp2build/Soong, since the depfile for Soong's main output, the build.ninja file, didn't contain the list of Android.bp files. bp2build only reran when Soong itself changed, which happens regularly while developing bp2build, but not at all while modifying Android.bp files.

This change correctly dumps the list of all Android.bp files in the tree to the depfile for out/soong/build.ninja, therefore correctly triggering a re-run of bp2build when any Android.bp file changes.

Test: GENERATE_BAZEL_FILES=true m nothing; edit an Android.bp file; GENERATE_BAZEL_FILES=true m nothing -> successfully re-runs and regenerates out/soong/bp2build.

eb76c4319d bp2build: fix running from clean checkout.
bp2build is a Soong mode that returns as soon as the BUILD files are generated. This causes it not generate the build.ninja file, which the Ninja process executing soong_build itself expects to produce as an output. If there isn't an existing build.ninja file generated from a previous build, GENERATE_BAZEL_FILES=true m nothing will fail.

This CL generates the expected files as a workaround, and also makes GENERATE_BAZEL_FILES=true skip the Kati/Ninja steps in soong_ui since they aren't needed.

Implement bp2build codegen as a discrete step that runs after an

PathContext, so this CL also makes a BpToBuildWrapperContext that
conforms to PathContext by adding two method implementations.

4133ce6912 Add bp2build mode to soong_build.
This CL adds a new CONVERT_TO_BAZEL env var, and a bp2build goal. It
reuses the queryview architecture, but registers no mutators before
converting to BUILD files. This gives us a blank slate of the module
graph to work with, and create a shadow/alternate pipeline of mutators
to converge the Bazel BUILD graph to be semantically equivalent with the
Android.bp graph (after apply its current set of mutators).

The command to do so is:

    $ CONVERT_TO_BAZEL=true m bp2build

To not clobber with queryview, the generated files are in
out/soong/bp2build.

5ba7e479d1 Create a AOSP Bazel overlay workspace with Soong
The Bazel overlay is a directory at out/soong/bazel_overlay that
replicates the layout of the AOSP Soong module tree, but as a Bazel
workspace. Each Soong module variant is represented as a BUILD target
created with the `soong_module` rule.

To create this overlay, run `m bazel_overlay`.

A `soong_module` target can depend on other `soong_module` targets.
These dependencies replicate each module's `directDeps` in the Blueprint
graph, just before `PrepareBuildActions`.

This enables users to use bazel query as a way to introspect the Soong
module graph. For example,

- Direct reverse dependencies of //bionic/libc:generated_android_ids in
//bionic/libc/...:

$ bazel query 'rdeps(//bionic/libc/...,
//bionic/libc:generated_android_ids, 1)'
//bionic/libc:libc_bionic_ndk--android_recovery_arm_armv7-a-neon_static
//bionic/libc:libc_bionic_ndk--android_ramdisk_arm_armv7-a-neon_static
//bionic/libc:libc_bionic_ndk--android_arm_armv7-a-neon_static_com.android.runtime
//bionic/libc:libc_bionic_ndk--android_arm_armv7-a-neon_static
//bionic/libc:generated_android_ids

- Why does com.android.runtime depend on lzma?

$ bazel query
'somepath(//bionic/apex:com.android.runtime--android_common_com.android.runtime_image,
//external/lzma/...)'
//bionic/apex:com.android.runtime--android_common_com.android.runtime_image

//system/core/libunwindstack:libunwindstack--android_arm_armv7-a-neon_shared_com.android.runtime
//external/lzma/C:liblzma--android_arm_armv7-a-neon_shared_com.android.runtime

- What does the dep graph of //bionic/libc:crtbegin_so look like?

$ bazel query
'deps(//bionic/libc:crtbegin_so--android_arm_armv7-a-neon)'
--output=graph > graph.in && dot -Tpng < graph.in > graph.png

modules with satisified dependencies are built.

87b17d1ff4 Use SRCDIR as a working directory
The existing behavior of using the build directory as the working
directory is useful if you want to move/copy the output directory around
and SRCDIR still refers the the source. But, it's more useful to have
the source directory be the working directory. Tools like cpp(__FILE__)
and other debug prints embed relative paths from the working directory.
We also have tools that expect the working directory to be $TOP.

Instead of putting all the blueprint registrations in soong_build,
put them all in init() functions.  This puts the registration next

d3ba039f74 Separate HostOrDevice out of Arch
Take HostOrDevice out of Arch, and put it into AndroidModuleBase
instead.  Also separate out the host vs. device mutator from
ArchMutator.  This will make it possible for genrules to depend
on a host tool, regardless of which host arches it is compiled
for.

SDK prebuilts need to be treated differently than other prebuilts.
They are used like a normal Java prebuilts when compiling java files,
but they are also used as aapt includes when compiling apps, and they
provide prebuilt aidl files when compiling aidl sources.  Create a
new module type so dependers can determine what kind of dependency
they are.

68f55102da Support dependencies on environment variables
Ninja can't depend on environment variables, so modifying build
behavior based on environment variables requires coordinating
between the soong script that invokes ninja and the soong_build
manifest generator.

Allow any module to call Config.Getenv to get the contents of an
environment variable while registering a dependency on it.
After all modules have been processed write out the state of
all used environment variables to a JSON file called
.soong.environment.  During the next build the soong script
will use the soong_env tool to compare the contents of
.soong.environment to the current environment, and force a
build manifest regeneration by deleting the .soong.environment
file if any variables have changed.

suite, but no way to reset it.  Allow them to specify test_per_src: true,

c403f7ce6d Add support for cc_test.
This behaves slightly differently than it does in the make based build.

1. The make based build manually passes -DGTEST_OS_ANDROID (or
   whatever). gtest-port.h already has logic that does this, so it's a
   no-op.
2. Host libraries are named identically, rather than libgtest_host.

files", which will only be built if another module that needs to build
depends on them.  For every target, add a module-install and a
module-checkbuild target that create dependencies on those files,
and then add a global checkbuild target that depends on all the
module-checkbuild targets.  Also add a module target for each module
that depends on module-install and module-checkbuild.
