Standalone system server jars are dynamically loaded by system server
using a `PathClassLoader` whose parent is `SYSTEMSERVERCLASSPATH`. They
are listed in `PRODUCT_STANDALONE_SYSTEM_SERVER_JARS` and
`PRODUCT_APEX_STANDALONE_SYSTEM_SERVER_JARS` in Makefile. We need to
dexpreopt them to achieve better performance.

This change adds a Soong module that stores the paths to the compilation
artifacts of system server jars in a variable, which will then be
consumed by Make to check if the artifacts are installed. When the check
fails, it means that dexpreopting is not working for some system server
jars and needs to be fixed.

This is necessary in order to expose the copy rule to Ninja. Otherwise
Ninja has a build rule that depends on the copied jar (namely, dexpreopt
commands for all subsequent system server jars that have the current one
in class loader context), but no rule that creates it, so Ninja fails
with a "no rule to make ..." error.
The change only affects system server ed in Android.mk
Previously the problem existed, but was hidden by the fact that the only
system server jar defined in Android.mk was the last one on the list, so
no other jar depended on it. Now that updatable apex jars are also
dexpreopted (https://r.android.com/1828115) the problem was uncovered.

This special-casing is actively unhelpful nowadays, as it breaks
callstack unwinding and symbolisation by tools that work using the
on-device debug info (e.g. perfetto's profilers). It's also highly
surprising that eng builds have less debug info than userdebug/user.
As far as I can tell, the history behind this case is (with some
internal-only references as the context is in the review comments): the
minidebuginfo was originally rolled out in device-specific makefiles
(e.g. ag/2433691). Eng builds were excluded, presumably due to time/size
concerns for rebuild+resync workflow, as well as the assumption that
engineers using eng builds already have the necessary debug info
off-device. Later, as some more makefile variables were introduced, the
conversation in ag/990059 shows that the overheads were no longer a
concern, and the last patchset generalised the option to include eng
builds. However at a later point, during device-specific makefile
cleanup, the eng-exclusion got restored: ag/2455645. This then ended up
in the makefile->soong transition, leaving us with the current special
casing that is undesireable.
Checking things with an internal master build on my workstation:
dexpreopting system services is 10s regardless of this minidebuginfo
flag, and the resulting odex size is 37MB vs 38MB. Overall, I only see 4
dexpreopt invocations as part of a local build, so the effect of this
patch should be negligible.

For running dex2oat on the target_files, the paths should be use the
device install path instead of the path starting with $(OUT).
So add usesTargetFiles option and basePath option which indicates
extracted path. With those options, the path is replaced with

Dexpreopt uses AAPT to parse `targetSdkVersion` from the manifest, so it
the generated dexpreopt.sh script that calls AAPT must depend on it,
otherwise AAPT might not be built by the time it is used. Tool
dependencies are handled via the global Soong config and the
DEXPREOPT_GEN_DEPS variable that Soong generates for Make. This config
always uses Soong tool paths, like out/soong/host/linux-x86/bin/aapt
rather than out/host/linux-x86/bin/aapt.
This CL fixes a mistake in dexpreopt rule that used context-dependent
AAPT path (so, when called from Make, the dependency was on Soong tool,
but a Make tool was actually used, so it failed sometimes).

There are modules that would have passed verify_uses_library check, but
don't run it for some reason (the check gets enabled either with an
explicit setting, or if the module has nonempty <ues-library> lists in
the build properties). Previously all such modules were assumed to have
empty CLC, which is not always true. In particular, compatibility
libraries are ignored, which affected e.g. Calendar and messaging apps.

the manifests of Java modules, but 1) worked for XML manifests, and 2)

In cases when class loader context cannot be computed at build time and
verify_uses_libraries check is relaxed (RELAX_USES_LIBRARY_CHECK=true)
dexpreopt uses a special compiler filter that suppresses AOT-compilation
to native code and applies only those optimizations that do not require
class loader context. Previously the "extract" filter was used. Now ART
supports using "verify" filter in this configuration.

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".

Test: Manually add some mismatch between the libraries in the Android.bp

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).

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).

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.

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.

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

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

With the addition of apexes and /system_ext some of the bootclasspath

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,

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.

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:
$ adb logcat | grep 'mismatch'
# empty
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 2>/dev/null | grep '^classpath'
classpath = PCL[]
$ oatdump --oat-file=out/target/product/walleye/system/framework/oat/arm64/services.odex 2>/dev/null | grep '^classpath'
classpath = PCL[/system/framework/com.android.location.provider.jar*1989208671]
$ oatdump --oat-file=out/target/product/walleye/system/framework/oat/arm64/ethernet-service.odex 2>/dev/null | grep '^classpath'
classpath = PCL[/system/framework/com.android.location.provider.jar*1989208671:/system/framework/services.jar*4040443083:/system/framework/services.jar!classes2.dex*2210087472]
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
$ adb logcat | egrep -io 'system_server: .*load.*/system/framework.*'
