As more phony rules move either to the packaging kati run, or soong, the

rules.
So I added --top_level_phony to Make that assumes that all leaf nodes

do not have a '/' in them are phony targets.
The existing phony-looks-real check in Kati should prevent these from
being real generated files, and our source tree shouldn't have any

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.

Use --no_ninja_prelude and move local_pool & _kati_always_build_ into

when Goma is enabled, and it allows us to include more than one

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.

This reverts commit 09f4540d66.
Fixes the raw call to net.Listen in the tests to go through the listen()
helper and use the long socket path fallbacks.
Removes the use of timeouts from the tests -- the behaviors being tested
did not rely on timeouts, so removing them will reduce the flakiness if
the build is heavily loading the machine at the same time the test is
running.
Also fixes some potential nil pointer dereferences.

This reverts commit 96c957ae20.
Fixes issues on some machines where the socket in TMPDIR ended up with a
unix domain socket pathname over 107 characters long, which Go will
reject due to underlying limitations in the system calls. If this
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
instead of the underlying file, sending a message over a unix domain
socket will block if the reader isn't reading, and sandboxing was
preventing us from running `ps`.

This will allow us to track (and eventually limit) the commands that the
build references via $PATH. These are mostly implicit dependencies on
the host system -- for Linux, we assume something similar to Ubuntu
14.04 with a few extra packages, but this will let us better define
that.
This will not catch uses of tools with absolute paths (/bin/bash, etc),
but most uses shouldn't be relying on absolute path names anyways.

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.

Get a list of leaf nodes in the dependency graph

One major output difference between the pure make implementation and
this one is that report_config in Go is implemented using embedded

embedded echo commands. This seems to work fine for both bash and zsh,

Instead of pairing the reading of CleanSpec.mk files with the reading of

This way we only read Android.mk files once after a clean/sync. We'll

significantly faster than reading all the Android.mk files.

This way we only have one way to start a build, which always has logging

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.

Instead of calling SetNinjaBuildDir, pass it to bootstrap.bash, so that
the bootstrap package can set it consistently during bootstrapping and
normal execution.

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

MAKELEVEL and MAKEFLAGS were are both unset by makeparallel when invoked
from Make. In preparation for removing the Make wrapper (and
makeparallel), strip them in soong_ui as well.
Add MFLAGS for completeness.

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.
So in preparation to remove the Make wrapper, support a simplified form
of this syntax, roughly equivalent to what the shell supports if
specified before the command (<NAME>=<VALUE>).
Test: m -j blueprint_tools

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').

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.

I removed *.txt from the installclean list yesterday, but it turns out
that android-info.txt being removed was the only thing triggering
system.prop to be rebuilt on the incremental build servers. So continue
android-info.txt so that the version information in system.prop is
correct.
I'll follow this up with a more complicated change to make the
system.prop generation depend on the build number/versions more
directly, but that's a more complicated change since we need to change
how the build number file is written.

For *.ini/*.txt files we should be recreating them as the instructions
change, so we shouldn't need to remove them. The biggest reason to
remove them is that the auto-installclean was removing
$PRODUCT_OUT/build_fingerprint.txt just after Kati wrote it out, causing
the fingerprint to be blank on builds where the auto installclean code
ran.
There's no reference to xlb in our tree, and it's been around since the
beginning of git history, so remove it.
