3d60b115a0 Allow boards to turn overriding commands into an error
Many board still have this problem, but if we can switch some over,
we'll prevent global problems and have the ability to clean boards up
one-by-one.

32a669b01b Use our own TMPDIR
Some people have run into issues where /tmp is on a smaller partition
than their main source tree, and if it fills up (or only has a few GB
free), their builds can start failing.

There may also be a subset of people whose /tmp may be slower than their
out directory -- if they put their src and out trees on a SSD, but keep
/tmp on a spinning HDD.

d9429e6ff2 Handle Scanner errors in kati output filter
If Kati ever wrote a line over 64k characters, the scanner in soong_ui
would error, and Kati would hang trying to write into the pipe. Now if
the Scanner errors out, fall back to copying directly from the pipe to
the output.

Test: Add $(warning $(shell find frameworks)), does not hang

e7945d76ac Make GOROOT consistent
We were previously setting GOROOT to "prebuilts/go/linux-x86" during the
ninja executions when we were running Soong. But we can also run Soong
during the main ninja execution, were GOROOT was unset. When the GOROOT
was unset, the default GOROOT in our Go installation is
"./prebuilts/go/linux-x86" (note the extra ./).

This would cause g.bootstrap.goRoot to change between some soong runs,
causing us to rebuild all go programs (and anything depending on them)
more often than necessary.

So instead, keep GOROOT undefined when running Soong. Everything that
matters is using runtime.GOROOT(), which will fall back to the default.

Continue setting $GOROOT for bootstrap.bash, otherwise it fails when
there is no system provided go binary. What we give bootstrap.bash
doesn't really matter, since we don't actually use the blueprint wrapper
in Android.

Test: m blueprint_tools; touch bionic/libc/tzcode/new.c;
      m blueprint_tools <doesn't rebuild everything>

ed86952403 Normalize LANG / LC_* environment
This ensures that the current locale supports UTF-8, and that we're
getting a consistent (but still supported by the system) locale for
every configuration except user-facing messages. This should eliminate
any reproducibility problems around sorting, formatting, etc for all
built products, while still showing localized error messages where
available.

0c51851f08 Apply kati output rewriting to dumpvars
This way we strip out ANSI codes when using dumb terminals. It's likely
overkill to use katiRewriteOutput, but we should rarely see any output
on stderr while dumping variables. This also lets us turn on kati_stats.

18099fd856 Build with OpenJDK 9 -target 1.8 by default (attempt 4).
This is cherry-picked from attempt 3, which was reverted
due to http://b/70862583.

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

13f23a2753 Build with OpenJDK 9 -target 1.8 by default except for errorprone.
(This is cherry-picked from the first attempt to submit this CL
topic, which was reverted after 3 hours because of bug 70286093;

7709a05770 Test for dangling rules in make checkbuild
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
sandboxing configurations.

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.

59fdf96fcf Split CleanSpec processing out of main Kati run
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 adds about 50ms if kati doesn't need to reread the CleanSpec.mk
files. Reading all the CleanSpec.mk files takes about a second.

Bug: 35970961
Test: m clean; m nothing; m nothing
Test: Add CleanSpec.mk line, see it executed.

99a75cd2a5 Obsolete bootstrap.bash and ./soong wrappers
We can call directly into the blueprint bootstrap.bash using values that
soong_ui has already calculated.

Instead of calling into blueprint.bash, build minibp with microfactory,
and directly run ninja. This allows us to get individual tracing data
from each component.

Test: m -j blueprint_tools
Test: m clean; m -j blueprint_tools

b64fc1cab5 Run the Finder and make its results available to Kati
The Finder runs roughly 200ms faster than findleaves.py in aosp,
and runs roughly 400ms faster in internal master.

e0879fc3ae Add --skip-make to replace Soong's blueprint wrapper with soong_ui
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.

Test: rm -rf out; m --skip-make libc
Test: rm -rf out; m libc; m --skip-make libc
Test: rm -rf out; mkdir out; cd out; ../bootstrap.bash; ./soong libc
Test: build/soong/scripts/build-ndk-prebuilts.sh
