android-build-prod (mdb) d08726ac76 Merge "Pass TARGET_DEVICE_DIR from dumpvars to later kati runs" 2018-05-02 17:35:34 +00:00
Dan Willemsen 6ab79db2e6 Pass TARGET_DEVICE_DIR from dumpvars to later kati runs
The find commands used to locate the BoardConfig.mk can't be optimized
by Kati, so we're currently spending ~125ms three times during every
build (dumpvars, cleanspec, and the main kati run). Preserve the value
of TARGET_DEVICE_DIR from the dumpvars run so that we only need to run
the find commands once.

Bug: 78020936
Test: out/build-taimen.ninja is identical
Test: out/soong.log shows that we're not running these finds again

Dan Willemsen ebfe33ad80 Remove more problematic env vars
I got a report of a user exporting CDPATH in their shell and causing
strange issues in the build. We should never need this value (and it
probably shouldn't be exported from the shell either -- that was their
workaround).

NDK_ROOT causes issues with Android.mk files thinking that they're
building with the ndk (like external/googletest/googletest/Android.mk).

we'll prevent global problems and have the ability to clean boards up

Dan Willemsen 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.

Dan Willemsen 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

Dan Willemsen 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>

Dan Willemsen 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.

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

Tobias Thierer 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

Colin Cross 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,

Dan Willemsen 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.

Dan Willemsen 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.

Dan Willemsen 091525e15c Parse environment options from the command line
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>).

Dan Willemsen 9b58749f30 Support more ways to pass -j/-k
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').

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.

to occur in the name.

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.

Dan Willemsen 0c3919e996 Fix OUT_DIR_COMMON_BASE with soong_ui
Currently, Kati is the only one that is respecting OUT_DIR_COMMON_BASE,
causing the build to fail when ninja tries to match up the Soong and
Kati ninja files.

The soong_ui.bash script change is necessary to move the microfactory
built outputs to the correct location.

The config.go change takes care of setting OUT_DIR in the environment of
every subprocess, so that we could remove the OUT_DIR_COMMON_BASE
handling from Make once the USE_SOONG_UI=false path goes away.

Dan Willemsen c38d366d78 Updates for the new ckati drop
We can start removing out directories again in multiproduct_kati, since
the opendir bug has been fixed.

Add --color_warnings to the Kati command line. Since this is different
from Make, take this opportunity to reorder the command line to make
more sense. This wasn't done before because kati forces a regen whenever
the command line changes.

Dan Willemsen 29f88279ba Filter kati output to collapse verbose messages
1. Collapses the "including .../Android.mk ..." lines like ninja does,
so that we overwrite the last line if there wasn't anything else to
print.
2. Strips ansi control codes so that log files don't include unreadable
characters.

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.

 -only-soong   1m20s
 <none>        13m

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
