Before this CL topic, the build toolchain for .java source files
used OpenJDK 8, targeting 1.8 (v52 class files) by default.
This CL topic switches the default to OpenJDK 9, but still
targeting 1.8 (v52 class files) by default. If USE_ERROR_PRONE
is set to true, then the default remains OpenJDK 8.
Code in the Android platform should generally be unaffected,
but if host tools that are now compiled and run using
OpenJDK 9 are causing problems for your team, then let me
know.
To manually switch back to the old behavior for now (continue
using OpenJDK 8), run this command in your shell:
export EXPERIMENTAL_USE_OPENJDK9=false
Bug: 69449021
Test: Treehugger
Test: "make core-oj", checked that compilation now uses
OpenJDK 9 javac -target 1.8
Test: Checked that this is still compiled using OpenJDK 8.

Get a list of leaf nodes in the dependency graph
from ninja, and make sure none of them are in the
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.

But uses soong_ui and ckati, so that we use a consistent make parser and

One major output difference between the pure make implementation and
this one is that report_config in Go is implemented using embedded
newlines in single quotes, while the make implementation uses `` with
embedded echo commands. This seems to work fine for both bash and zsh,
and report_config isn't meant to be machine-parsed anyways.

Instead of pairing the reading of CleanSpec.mk files with the reading of
Android.mk files, split them into separate, individually cachable steps.
This way we only read Android.mk files once after a clean/sync. We'll
still read the CleanSpec.mk files multiple times, but that's
significantly faster than reading all the Android.mk files.

This way we only have one way to start a build, which always has logging
/ tracing / etc, even if we don't need Kati.
There's two ways to use this:
As a direct replacement for mkdir out; cd out; ../bootstrap.bash;
./soong -- as long as --skip-make is always passed, we'll never run
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.

Make supports specifying all types of variables on the command line
(using =, :=, +=, and other variable references. When running soong_ui
through make/makeparallel these all effectively become environment
variables.

of this syntax, roughly equivalent to what the shell supports if
specified before the command (<NAME>=<VALUE>).

In preparation to remove Make/makeparallel from soong_ui startup, we
need to preserve compatibility with the different ways that make
supports the -j option.
Nothing changes unless Make/makeparallel is removed from the startup.
Once that is removed, not specifying a -j value will be equivalent to
'-j' instead of '-j1', like Ninja. A value will also be supported when
specifying -k, like Ninja (though specifying it alone will be equivalent
to '-k 0').

system.prop to be rebuilt on the incremental build servers. So continue

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 -keep; load out/multiproduct*/build.trace.gz
Change-Id: Ic060fa9515eb88d95dbe16712479dae9dffcf626
This is a replacement for build/tools/kati_all_products.sh using the new
Soong ui/build package. It doesn't even attempt to run ninja, and it can
be configured to run only the product config, or only the product config
and Soong.
For AOSP on my machine:
-only-config 1.4s
-only-soong 1m20s
<none> 13m

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
