8c35fcf4d5 Add non-fatal mode for verify_uses_libraries check.
The new mode is enabled with environment variable
RELAX_USES_LIBRARY_CHECK. If the variable is set to true, then a
verify_uses_libraries check failure does not fail the build, instead it
sets a special compiler filter "extract" for dexpreopt, which means that
the DEX file will be extracted, but it won't be compiled to native code.
Class loader context will be set to empty in this case (not &, as it is
going to be deprecated soon).

If the variable RELAX_USES_LIBRARY_CHECK is unset or set to something
other than "true", then the old behaviour of the verify_uses_libraries
check is preserved.

The intended use case for this flag is to have a smoother migration path
for the Java modules that need to add <uses-library> information in
the build files. The flag allows to quickly silence build errors. This
flag should be used with caution and only as a temporary measure, as it
masks real errors and affects performance.

verify_uses_libraries check is reworked so that it writes the error
message to a status file (which is used instead of the former timestamp
file). Currently the stored error message is not used, but it may be
used later to produce a warning. Dexpreopt command checks if the status
file exists and is nonempty; if that is the case, then compiler filter
is set to "extract".
Bug: 132357300

Test: Manually add some mismatch between the libraries in the Android.bp
      and Android.mk files for dexpreopted apps, build with
      RELAX_USES_LIBRARY_CHECK=true and obsserve that the build doesn't
      fail and they are compiled with compiler-filter "extract".
      Unset RELAX_USES_LIBRARY_CHECK and observe that the build fails.

8cbc5d269b Rework class loader context implementation.
The old representation consisted of a list of libraries (UsesLibraries),
a list of optional libraries (OptionalUsesLibraries) and a mapping from
library name to its build/install paths (LibraryPaths). The separation
into lists and map was necessary because of special handling of
compatibility libraries, which is now unified with normal libraries.

The new representation is a mapping from target SDK version to a tree
structure ClassLoaderContext. Each node of the tree represents a library
and contains library name, build/install paths and a slice of
subcontexts for dependencies. The same library may occur in the tree
multiple times in case it is a dependency of multiple libraries. The
order in which libraries are added matters (the resulting tree shape may
be different).

Test results have to be updated, as the resulting <uses-library> list is
reodered (previously it was a sorted list of map keys, and now it is
formed by a depth-first preorder traversal of the class loader tree).

8130c482ab Move part of logic from construct_context.py to Soong.
construct_context.py is a script that runs at Ninja stage and constructs
class loader context arguments for dex2oat. Previously it accepted lists
of library paths and concatenated them into one class loader context
string. The script also handled the dependency of "android.hidl.manager"
on "android.hidl.base" that is not tracked by the build system and must
be handled in a special way.

Now that class loader context representation is going to change from
flat lists to trees, passing paths to individual libraries as script
arguments is no longer possible, because a list of paths cannot
represent a class loader context tree. Passing the trees in a serialized
form is also inconvenient, because the script would have to parse them,
which would complicate it a lot.

Therefore this patch ports all the concatenation and "android.hidl.base"
handling to Soong. It is not possible to port the remaining script to
Soong because Soong has no information about the targetSdkVersiion of
the dexpreopted apps (it is in the manifest and sometimes in an APK, and
has to be extracted at Ninja time).

24813e1d80 Unify handling of compat and normal libs in class loader contexts.
Also, add tests for compatibility libraries in class loader context.

This CL separates special-case handling of compatibility libraries into
a "fixup" step that is done after class loader context is constructed by
Soong. This allows to handle compatibility libraries and normal
libraries uniformly, which should enable further simplification of class
loader context representation (in subsequent CLs).

Currently the only "fixup" step is removal of libraries from conditional
class loader context if they already are in unconditional context. This
check cannot be done at the time when the libraries are added to
conditional context, because the full uncoditional context is not yet
known at that time. Previously construction of unconditional context was
delayed, now it is no longer delayed and handled in the same way as
unconditional context, and the "fixup" does the filtering.

a54d33be77 Fail the build if dexpreopt cannot find path to a <uses-library>.
This doesn't apply to compatibility libraries (those added to
conditional class loader context base on the targetSdkVersion in the
manifest), because Soong doesn't know if they are needed or not (the
build rule that parses the manifest runs at Ninja stage).

In the future we may need to relax this and instead of failing the build
to disable dexpreopt in such cases. But currently there are no use cases
that fail.

Also, this patch replaces hardcoded install path with a constant.

75480154e2 Re-land "Move odexes of non-system apps into system_other"
Previously, the patterns in SYSTEM_OTHER_ODEX_FILTER only matched
subpaths of /system. Broaden this to match /<p> as well as /system/<p>.

Because SYSTEM_OTHER_ODEX_FILTER includes system_ext and product apps,
the immediate effect of this is that the odex and vdex files of
apps on those partitions move to system_other for A/B devices.

This makes the product and system_ext partitions smaller, which
in turn makes OTAs smaller.

fc24ad3d4e Propagate transitive SDK Java library dependencies to dexpreopt.
For some dependencies, like stubs, the SDK library may not be found at
build time (either because the implementation library is not among the
dependencies of the dexpreopted module, or because it's part of a
prebuilt, or because it's missing from the build altogether). In such
cases dexpreopt is useless, because dex2oat does not have access to the
full classpath (unless the &-classpath is used). Therefore do not
dexpreopt in such cases.

249386ad69 Add structured representation for colon-separated jar lists.
With the addition of apexes and /system_ext some of the bootclasspath
and system server jars have moved from /system to the new locations.
This has been implemented by using lists of colon-separated strings
called "apex-jar pairs" (although "apex" was misleading as it could
refer to "platform" or "system_ext", not necessarily a real apex).

Using the colon-separated string representation is inconvenient, as it
requires splitting and reassembling the list components many times,
which harms performance and makes error handling difficult. Therefore
this patch refactors the colon-separated lists into a struct that
hides the implementation details.

5f364b63b8 Rewrite construct_context.sh in Python.
This allows to reuse SDK version comparison routine from other Python
scripts. With the addition of non-numeric versions comparison has become
more complex, and the deleted shell script did it incorrectly: it used
comparisons like `[[ "S" -lt 28 ]]` which results in "true" as strings
are converted to zero in numeric context. This resulted in adding legacy
libraries to class loader context of apps targeting recent SDK versions.
The error was masked because currently there is only one non-AOSP app
that uses the script (GoogleDialer), and it targets numeric SDK version.

The order is non-optimal if some jar X precedes its dependency Y. In

PRODUCT_BROKEN_SUBOPTIMAL_ORDER_OF_SYSTEM_SERVER_JARS to true in the

This is a prerequisite change for moving core-icu4j to a separate

6cf2c0c197 Fix host path for dexpreopted system server modules defined in Make.
Previously there was a discrepancy between the generated paths for
Soong modules that used "out/soong/system_server_jars" and Make modules
that used "out/system_server_jars". This happened because the default
output directory is $OUT/soong for the normal Soong config and jsut $OUT
for the reduced "null config" created by dexpreopt_gen.

As a result, class loader context for system server jars defined in Make
was referring to nonexistent jars, which caused non-fatal dex2oat errors
(the build was not broken, so the errors remained unnoticed):

dacc6c56f1 Simplify the construction of class loader contexts for system server jars.
This reworks CL https://r.android.com/1180134 as follows:

1) Do not reorder the list of system server jars passed from Make to
  Soong via the product variable PRODUCT_SYSTEM_SERVER_JARS. This means
  that for some products the order of jars on the system server
  classpath may be non-optimal: a jar X that depends on Y may be
  dexpreopted before Y, so that all references to the classes and
  methods from Y wil be unresolved.

  Unfortunately for such products, fixing the order is not a simple
  matter of rearranging their PRODUCT_SYSTEM_SERVER_JARS, because the
  conflicts may arise when the product-specific variable gets merged
  with the common variable.

2) As a consequence of 1), do not add artificial dependencies between
  system server jars: this is now impossible, as it would create
  circular dependencies for those products that have non-optimal order
  of jars.

3) Copy dex files for system server jars to a predefined build location.
  This is necessary because at the time when Soong generates class
  loader context for k-th jar, it needs to know the paths to jars 1 ..
  (k-1), and it might have not processed those jars yet (so Soong can't
  query the paths from the modules).

  This approach is similar to the way Soong handles bootclasspath jars.

4) Do not exclude from dexpreopting system server jars that are not
  Soong modules (those that are Make modules). The previous CL excluded
  them because Make modules do not have ModuleContext. But it turns out
  that ModuleContext is not necessary, as all the information is passed
  via the dexpreopt config.

Test: aosp_walleye-userdebug boots and there are no messages in the
  logcat regarding class loader context mismatch:

3aff5787e2 Simple refactoring of prefix related functions.
Rename the two prefix-in-list funcs so that their usages are clearer.
Also find and replace all the code that essentially does either.

This introduces additional loops in some places, but I think the added
readability and simplicity outweighs the performance degradation, which
should be negligible anyway.

f3ff010bd4 Use precise class loader context for system server jars.
This patch excludes non-Soong system server jars from dexpreopting.

System server jars should be dexpreopted together for better
performance: each jar should have all preceding system server jars
in its class loader context (that is passed to dex2oat and recorded
in the resulting .oat file to be used by the loader).

This means that we need a total order on system server jars. The
default order provided by PRODUCT_SYSTEM_SERVER_JARS is not good, as
it does not always respect genuine dependencies between jars (counter-
examples are rare, but non-trivial to fix: b/148219586).

This patch adds a post deps mutator pass that creates additional
dependencies and enforces global order. These are later used to
generate precise class loader contexts and system server classpath.

Test: Class loader contexts in the oat files for system server jars
  match expectations:

  $ oatdump --oat-file=out/target/product/walleye/system/framework/oat/arm64/com.android.location.provider.odex | grep '^classpath'
  classpath = PCL[]
  $ oatdump --oat-file=out/target/product/walleye/system/framework/oat/arm64/services.odex | grep '^classpath'
  classpath = PCL[/system/framework/com.android.location.provider.jar*1919890654]
  $ oatdump --oat-file=out/target/product/walleye/system/framework/oat/arm64/wifi-service.odex | grep '^classpath'
  classpath = PCL[/system/framework/com.android.location.provider.jar*1919890654:/system/framework/services.jar*4269704903:/system/framework/services.jar!classes2.dex*134345935]
  ...

Test: The phone boots and logcat has no scary messages related to
  class loader contexts:

  $ lunch aosp_walleye-userdebug && m
  $ adb reboot bootloader && fastboot flashall -w && adb wait-for-device
  $ adb root
  $ adb shell stop
  $ adb logcat -c
  $ adb shell setprop dalvik.vm.extra-opts -verbose:oat
  $ adb shell start

c52aaf11d0 Move generation of the dexpreopt tool paths into Soong.
The dexpreopt global config is now split into the part that is generated
from make (in build/make/core/dex_preopt_config.mk) and the part that is
generated from Soong. Since the goal is to generate the dex2oat path from
Soong dependencies, the old GlobalConfig.Tools struct is simply repurposed
for the Soong generated config, although the intention is to allow more
settings to migrate from make to Soong, and hence from GlobalConfig to
GlobalSoongConfig.

Since the new dexpreopt_soong.config is written from a Soong-created ninja
rule, it doesn't need to be rewritten to out/soong/<device>/ like the old
make-created config file.

Test: m
Test: env USE_DEX2OAT_DEBUG=false m
  (check that out/soong/dexpreopt_soong.config points to dex2oat instead of dex2oatd)

3391a1e85f Respect JIT-zygote config when generating boot image location.
Earlier CL Ida40dfae8c83bf7c2e737d5c7ea418e1197ad826 introduced
Soong-generated Make variable 'DEXPREOPT_IMAGE_LOCATIONS'. That CL was
erroneous in that it did not take JIT-zygote config into account and
generated identical location for "boot" and "apex" boot images.

This caused build breakages, because in case of JIT-zygote config the
two variables 'DexPreoptImages' and 'DexPreoptImageLocations' in the
module's dexpreopt.config were out of sync: 'DexPreoptImages' was
for the "apex" image, and 'DexPreoptImageLocations' was for the "boot"
image.

CL I9a91fc48e54d7d43abec2cb2b5a11e3581db380b introduced a workaround
for this problem: incorrect 'DexPreoptImageLocations' from the module
dexpreopt.config was ignored, and instead boot image location was
manually reconstructed from 'DexPreoptImages'. This workaround would
not work when we start using boot image extension and location will
become more complex.

This CL fixes the way 'DexPreoptImageLocations' is generated by
spliting the 'DEXPREOPT_IMAGE_LOCATIONS' variable in two variables
depending on the boot image flavour "boot" of "apex". This is
aligned with the way other similar variables are generated.

Test: aosp_walleye-userdebug boots.
Test: walleye_jitzygote-userdebug builds
  (on git_rvc-release branch with this CL cherry-picked).

3380531d80 Rollback to the legacy way of computing boot image locations.
This fixes JIT-zygote builds (b/146462581). The fix is a workaround:
boot image location is computed from boot image filename instead of
using the pre-computed location from the module dexpreopt config.

Currently parts of the dexpreopt module config use boot image name
that is hard-coded in Makefiles, and other parts use boot image name
that is generated by Soong. This is exacerbated by the fact that
"default" boot image config in JIT-zygote builds consists partly of
the "apex" boot image, and partly of "boot" boot image.

Test: walleye_jitzygote-userdebug builds.

4d2eeed0da Use boot image extension for framework libraries.
This patch splits the system boot image in two parts:

  - The ART boot image. This is the primary boot image that is
    included in the ART apex and contains dexpreopted Core Libraries.

  - The framweork boot image extension. It depends on the ART boot
    image and contains framework libraries.

The third "apex" boot image (used in the JIT-zygote experiment)
remains unchanged; it is a monolithic primary boot image that
contains both libcore and framework libraries.

Dexpreopting of APKs now uses the framework boot image extension
(which in turn pulls in the ART boot image as a dependency).

12b8d427c7 Move odexes of non-system apps into system_other
Previously, the patterns in SYSTEM_OTHER_ODEX_FILTER only matched
subpaths of /system. Broaden this to match /<p> as well as /system/<p>.

Because SYSTEM_OTHER_ODEX_FILTER includes system_ext and product apps,
the immediate effect of this is that the odex and vdex files of
apps on those partitions move to system_other for A/B devices.

This makes the product and system_ext partitions smaller, which
in turn makes OTAs smaller.
