Chris Parsons ec1a3dc6f8 Subsume INTEGRATED_BP2BUILD into other env modes
This refactors bazel-build mode determination logic in soong_ui so it's
clearer which of three possible modes are being used in a given
invocation (NO_BAZEL, GENERATE_BUILD_FILES, or MIXED_BUILDS).

Test: bootstrap tests

Lukacs T. Berki 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 .

Jingwen Chen 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.

Test: rm -rf out/ && GENERATE_BAZEL_FILES=true m nothing && m libc

Anton Hansson 5e5c48b2b5 Add support for skipping just kati
The existing --skip-make flag disables both the config step and the kati
step in the build. Add support for a --skip-kati flag that skips just
the kati step, and refactor things so that the logic is shared between

Jingwen Chen cda22c9bb9 Refactor 'in_make' to mean Kati is not skipped.
In Nougat and before, Make wrote a marker file to indicate that
soong_build was invoked from Make to change certain behaviors of Soong
at build time.
https://cs.android.com/android/platform/superproject/+/android-7.1.2_r36:build/core/soong.mk;l=70-73;drc=ae18638b0406ad107b0882a02a13cdd8b92f2a4e

Things have changed, and now soong_build is invoked from soong_ui, which
supports a --skip-make configuration flag:
https://cs.android.com/android/platform/superproject/+/master:build/soong/ui/build/build.go;l=31-33;drc=680387bf1d3ce7cbc77f535be7c42cec411b1687

Thus, the various remnants of 'EmbeddedInMake' and 'inMake'
configuration are misleading, since soong_build is no longer invoked
from Make. This CL refactors all instances to actually mean that
Kati is enabled (not skipped with --skip-make), and will run after
soong_build finishes, so Kati-specific behavior like the AndroidMk
singleton should run.

Dan Willemsen 570a292bab Better handling of low memory situations
Drop down to a single high-mem task when we've got <=16GB, as the system
probably isn't completely free RAM, ninja will be using a couple gigs,
along with whatever "normal" actions will be running concurrently. So
it's unlikely that we can handle two 6-8GB actions along with everything
else.

Also print warnings when we detect <=16GB total RAM, or when we're
running more parallel jobs than than we have GB RAM. These both notify
the user and suggest lowering the `-j` value if they run into problems.

Test: fake totalRAM to [0.5,8,16]GB, checking warning
Test: fake totalRAM to 17GB, `m -j4 nothing` has no warning

Dan Willemsen 6587beddfa Turn on ninja phony outputs
This replaces the _kati_always_build_ hack with a ninja feature so that
ninja can actually understand what's happening. This means that we can
turn on some more options and checks around expected output filenames:

* Remove the output file(s) before the command executes
* Error if the output file(s) don't exist after the execution
* Error if the output is a directory

They're turned on immediately during the soong bootstrap runs, as those
run a limited number of rules. The main ninja execution does not remove
the output files, and prints warnings instead of errors for the others.
I'll turn them on as we understand how often those warnings are seen.

Colin Cross 8b8bec3b3a Create a highmem pool and put metalava into it
Create a highmem pool based on the total RAM and the number of CPUs,
with an override via the NINJA_HIGHMEM_NUM_JOBS variable.  Put
metalava into the highmem pool.

Ninja does not support nested pools, and when goma or RBE is enabled
the maximum ninja parallelism is set very high with local jobs in a
local pool.  When both the local pool and highmem pool are enabled,
the total number of local jobs will be as high as the sum of the sizes
of the two pools.  Keep the highmem pool limited to 1/16th of the
local pool when remote builds are enabled to try to minimize the
effect while still limiting highmem jobs.

Dan Willemsen fb1271a52b Add a Kati-based packaging step
The idea is that we'd move the installation and packaging tasks over to
it, using data from Soong & the Kati reading Android.mk files.

This would allow us to make more fundamental changes about how we
package things without having to adjust makefiles throughout the tree.
Possible use cases:

* Moving some information from Soong's Android.mk output to a file read
  by the packaging step may allow us to read the Android.mk files less
  often, speeding up builds.

* Refactoring our current two-stage ASAN builds to run the Kati build
  step twice, writing into different object directories, then have a
  single packaging step that reads both outputs. Soong already has the
  capability of writing out a single ninja file with all the asan
  combinations.

* Running two build steps, one building the system-related modules
  using a "generic" device configuration, and one building the vendor
  modules using a specific device configuration. This could enforce a
  GSI/mainline system vs vendor split in a single build invocation.

* If all installation is through this tool, it will be much easier to
  track what should no longer be installed on an incremental build,
  reducing the need for installclean.

* Changing PRODUCT_PACKAGES should be a much faster operation, which
  means we could keep track of local additions to the images. Then
  `mma` would be more persistent, instead of installing something once,
  then never updating it again.

Eventually we plan on switching from Kati to something Go-based, but
this is a more incremental approach while we clean up everything else.

Currently, this just moves the dist-for-goal handling over to the
packaging step, so that we don't need to read Android.mk files when
DIST_DIR changes, or we switch between dist vs not.

Dan Willemsen 2997123f73 Refactor Kati logic
Make the cleanspec & Android.mk runs of kati use much of the same code
and arguments.

Also renames 'Kati' to 'KatiBuild' in many cases, in the the expectation
that we'll have a 'KatiPackage' step in the future.

Use --no_ninja_prelude and move local_pool & _kati_always_build_ into
the combined ninja file. This will reduce the need to re-read makefiles
when Goma is enabled, and it allows us to include more than one
Kati-generated ninja file in the build graph.

Dan Willemsen b82471ad6d Add a unified status reporting UI
This adds a new status package that merges the running of "actions"
(ninja calls them edges) of multiple tools into one view of the current
state, and gives that to a number of different outputs.

For inputs:

Kati's output parser has been rewritten (and moved) to map onto the
StartAction/FinishAction API. A byproduct of this is that the build
servers should be able to extract errors from Kati better, since they
look like the errors that Ninja used to write.

Ninja is no longer directly connected to the terminal, but its output is
read via the protobuf frontend API, so it's just another tool whose
output becomes merged together.

multiproduct_kati loses its custom status routines, and uses the common
one instead.

For outputs:

The primary output is the ui/terminal.Status type, which along with
ui/terminal.Writer now controls everything about the terminal output.
Today, this doesn't really change any behaviors, but having all terminal
output going through here allows a more complicated (multi-line / full
window) status display in the future.

The tracer acts as an output of the status package, tracing all the
action start / finish events. This replaces reading the .ninja_log file,
so it now properly handles multiple output files from a single action.

A new rotated log file (out/error.log, or out/dist/logs/error.log) just
contains a description of all of the errors that happened during the
current build.

Another new compressed and rotated log file (out/verbose.log.gz, or
out/dist/logs/verbose.log.gz) contains the full verbose (showcommands)
log of every execution run by the build. Since this is now written on
every build, the showcommands argument is now ignored -- if you want to
get the commands run, look at the log file after the build.

Dan Willemsen 5af1cbe776 Ensure bpglob is built early
This matches the change to blueprint's blueprint_impl.bash:
https://github.com/google/blueprint/pull/213

It allows us to run bpglob during the two bootstrap phases, so we're
never running minibp or the primary builder in a later phase than
normal.

Also removes the dependency on out/soong/build.ninja from the main
phase, since it's never generated by the main phase anymore, and is
tripping the dangling dependency checks.

happens, we'll fall back to opening the directory, then using
/proc/self/fd/#/<file>, or manually creating a similar symlink in /tmp.

Also fixes some issues on Mac where os.Executable returns the symlink

socket will block if the reader isn't reading, and sandboxing was
preventing us from running `ps`.

Get a list of leaf nodes in the dependency graph

output directory.  This ensures that there are no
rules that depend on a file in the output directory
that doesn't have rule to generate it.  The check
will catch a common set of build failures where
a rule to generate a file is deleted (either by
deleting a module in an Android.mk file, or by
modifying the build system incorrectly).  These
failures are often not caught by a local incremental
build because the previously built files are still
present in the output directory.

Kati, and Soong will run outside of it's "make" mode. This preserves
most of the speed, and allows full user control over the Soong
configuration.

A (experimental, dangerous) way to temporarily bypass the product
variable and kati steps of a build. As long as a user is sure that
nothing has changed from the last build, and they know exactly which
Ninja targets they want to build (which may not be the same as the
arguments normally passed to 'm'), this can lead to shorter build
startup times.

The build now uses a prebuilt javac binary distributed with the
source, checking the host java version is no longer required.

Jeff Gaston efc1b412f1 Have Soong try to enforce that genrules declare all their outputs.
This causes Soong to put the outputs of each genrule into a temporary
location and copy the declared outputs back to the output directory.
This gets the process closer to having an actual sandbox.

This speeds things up a little bit, but the major win is that we don't
need to recursively call into the build during the auto installclean.

Dan Willemsen db8457cfec Move version checking from Make into soong_ui
When kati keeps state around, it has to regenerate the ninja file every
time the state is changed. So move the java version checking into
soong_ui, where we can parallelize it with other operations instead of
only checking it occasionally.

So that we don't have to load up all the makefile state just to remove
the output directory.

Starting from a completely empty out directory:
 kati:    16s
 soong_ui: 2.0s

From a minimal out directory (m -j blueprint_tools):
 kati:     3.8s
 soong_ui: 0.4s

Dan Willemsen 269a8c78e7 Add exec.Cmd wrapper for logging / sandboxing
Wrap os/exec.Cmd to use our Context and Config interfaces for automatic
logging and error handling. It also simplifies environment modification
based on the Config's environment.

This also adds sandboxing on Macs using sandbox-exec. A simple profile
is provided that only logs on violations, though multiproduct_kati on
AOSP has no violations. This isn't applied to ninja, only make / soong /
kati to start with. I measured <5% time increase in reading all
makefiles, and no noticable difference when kati doesn't regenerate.

I'd like to spin up a process to dump violation logs into our log file,
but the log reporting changed over the range of Mac versions that we
support, so that's going to be more complicated. Opening Console.app
works in all cases if you're local -- just search/filter for sandbox.

Linux sandboxing will be implemented later -- the sandbox definition is
opaque enough to support a different implementation.

Test: multiproduct_kati on AOSP master on Mac

Dan Willemsen 1e70446251 Add a Go replacement for our top-level Make wrapper
Right now this mostly just copies what Make is doing in
build/core/ninja.mk and build/core/soong.mk. The only major feature it
adds is a rotating log file with some verbose logging.

There is one major functional difference -- you cannot override random
Make variables during the Make phase anymore. The environment variable
is set, and if Make uses ?= or the equivalent, it can still use those
variables. We already made this change for Kati, which also loads all of
the same code and actually does the build, so it has been half-removed
for a while.

The only "UI" this implements is what I'll call "Make Emulation" mode --
it's expected that current command lines will continue working, and
we'll explore alternate user interfaces later.

We're still using Make as a wrapper, but all it does is call into this
single Go program, it won't even load the product configuration. Once
this is default, we can start moving individual users over to using this
directly (still in Make emulation mode), skipping the Make wrapper.

Ideas for the future:
* Generating trace files showing time spent in Make/Kati/Soong/Ninja
  (also importing ninja traces into the same stream). I had this working
  in a previous version of this patch, but removed it to keep the size
  down and focus on the current features.
* More intelligent SIGALRM handling, once we fully remove the Make
  wrapper (which hides the SIGALRM)
* Reading the experimental binary output stream from Ninja, so that we
  can always save the verbose log even if we're not printing it out to
  the console
