Cindy Zhou 18417cbd72 Skip apex dep check when sanitizer diag is enabled
To avoid adding ubsan to the apex allowed_dep list, this commit adds a
check on depedency tags to see if apex check should be skipped.
The check is only used on sharedLib dependencies when diag mode are enabled
for sanitizers.

Jiyong Park f7c3bbe433 Prebuilt stub not available to platform is handled correctly
When a shared library providing stubs is included in an APEX, only the
stub variant (i.e. version:"1", etc.) gets emitted to Android.mk. This
enforces that everything in the Make world to link to the stub providing
only the public APIs of the library. The non-stub variant (i.e.
version:"") isn't exposed, otherwise, others will be able to access
private part of the lib which isn't guaranteed to be stable.

This has been done by unhiding the stub variant when it is known that
the library is actually included in an APEX. Note that stub variants are
by default hidden.

The above mechanism however doesn't work when the shared library is
replaced by a prebuilt and when the APEX is also replaced by a prebuilt.
Then, the fact that the prebuilt library is actually in the APEX gets
lost.  In that case, AnyVariantDirectlyInAnyApex() returns false for the
prebuilt library. As a result, the stub variant remains hidden and not
emitted to Android.mk.

This change fixes the problem by checking if the lib isn't available for
the platform at all. If not available for the platform (e.g.
apex_available doesn't have "//apex_available:platform"), the lib is
assumed to be included in an APEX even when it actually didn't go
through the apex mutator (... because it's a prebuilt).

Paul Duffin 949abc03eb Rename apexDepsMutator to apexInfoMutator
Generally ...DepsMutator methods add dependencies between modules but
the apexDepsMutator does not which can be confusing. This renames
apexDepsMutator to apexInfoMutator and adds some extra documentation to
clarify its function. It also renames the registered name for the
mutator and its associated providers from apex_deps to apex_info.

Paul Duffin 9a89a2a0ea Move boot jars package check from make
Adds a singleton that traverses the module variants finding the ones
that are in the list (updatable and non-updatable) of boot jars and
add a ninja rule to ensure that they only contain packages from an
allowed list.

Replaces a hack that ignored any prebuilt boot jars supplied as dex
file with an equivalent one to ensure that they are still ignored.
A follow up change that switches to checking dex jars will allow the
hack to be removed.

The boot jars check can be strict or lax. If strict then all the boot
jars listed in the configuration must be found, otherwise it will only
check the ones it finds. It is strict by default unless
TARGET_BUILD_UNBUNDLED=true or ALLOW_MISSING_DEPENDENCIES=true.

Moves the script and data file from build/make.

Test: m check-boot-jars - for failing and passing cases

Colin Cross 0de8a1e17b Start using Providers instead of direct module access
Export information about static libraries, shared libraries and
exported flags through Providers instead of accessing the module
directly.  Much more is left to be converted, but this significantly
simplifies the dependencies on libraries with stubs by making it easy
for a module to masquerade as another by simply exporting the
providers from the other module.  Instead of depending on all the
versions of a library and then picking which one to use later, it
can depend only on the implementation variant and then select the
right SharedLibraryInfo from the variant.

instead of "10000" for libraries that specify "current" in their stubs

Colin Cross aede88c1c7 Reland: Deduplicate APEX variants that would build identically
APEX variants that share the same SDK version and updatability
almost always use identical command line arguments to build but
with different intermediates directories.  This causes unnecessary
build time and disk space for duplicated work.

Deduplicate APEX variants that would build identically.  Create
aliases from the per-APEX variations to the new shared variations
so that the APEX modules can continue to depend on them via the
APEX name as the variation.

This has one significant change in behavior.  Before this change,
if an APEX had two libraries in its direct dependencies and one
of those libraries depended on the other, and the second library
had stubs, then the first library would depend on the implementation
of the second library and not the stubs.  After this change, if
the first library is also present in a second APEX but the second
library is not, then the common variant shared between the two
APEXes would use the stubs, not the implementation.

In a correctly configured set of build rules this change will
be irrelevant, because if the compilation worked for the second
APEX using stubs then it will work for the common variant using
stubs.  However, if an incorrect change to the build rules is
made this could lead to confusing errors, as a previously-working
common variant could suddenly stop building when a module is added
to a new APEX without its dependencies that require implementation
APIs to compile.

This change reduces the number of modules in an AOSP arm64-userdebug
build by 3% (52242 to 50586), reduces the number of variants of the
libcutils module from 74 to 53, and reduces the number of variants
of the massive libart[d] modules from 44 to 32.

This relands I0529837476a253c32b3dfb98dcccf107427c742c with a fix
to always mark permissions XML files of java_sdk_library modules as
unique per apex since they contain the APEX filename, and a fix
to UpdateUniqueApexVariationsForDeps to check ApexInfo.InApexes
instead of DepIsInSameApex to check if two modules are in the same
apex to account for a module that depends on another in a way that
doesn't normally include the dependency in the APEX (e.g. a libs
property), but the dependency is directly included in the APEX.

Jooyung Han 698dd9f007 apexDepsMutator uses WalkDeps
apexDepsMutator marks all dependencies of apex modules. Previously, it
was converted from WalkDeps() to Top-down mutator to avoid the pitfall
of WalkDeps() bug. (It did't handle multiple visits via different
paths.)

Because WalkDeps() problem solved in aosp/1277516, apexDepsMutator can
be reverted to use WalkDeps().

Even though there's no observable difference between them, I revert this
for the up-coming change, which requires different pruning strategies
per apexes.

Jiyong Park 89e850ab84 mark platform un-availability
A module is marked unavailable for platform when 1) it does not have
"//apex_available:platform" in its apex_available property, or 2)
it depends on another module that is unavailable for platform.

In that case, LOCAL_NOT_AVAILABLE_FOR_PLATFORM is set to true for the
module in the Make world. Later, that flag is used to ensure that there
is no module with the flag is installed to the device.

The reason why this isn't entirely done in Soong is because Soong
doesn't know if a module will be installed to the device or not. To
explain this, let's have an example.

cc_test { name: "mytest", static_libs: ["libfoo"]}
cc_library_static { name: "libfoo", static_libs: ["libbar"]}
cc_library { name: "libbar", apex_available: ["com.android.xxx"]}

Here, libbar is not available for platform, but is used by libfoo which
is available for platform (apex_available defaults to
"//apex_available:platform"). libfoo is again depended on by mytest
which again is available for platform. The use of libbar should be
allowed in the context of test; we don't want to make libbar available
to platform just for the dependency from test because it will allow
non-test uses of the library as well.

Soong by itself can't tell whether libfoo and libbar are used only in the
context of a test. There could be another module depending them, e.g.,

cc_library_shared { name: "mylib", static_libs: ["libfoo"] }

can exist and it might be installed to the device, in which case
we really should trigger an error.

Since Make has the knowledge of what's installed and what's not,
the check should be done there.

Paul Duffin dddd5469ad Ignore PrebuiltDepTag when processing APEX contents
When a source and a prebuilt module are present in the same build a
dependency is added from the source module to the prebuilt module.
Previously, the code for generating the APEX did not recognize that
tag and in some cases (e.g. for cc_(prebuilt_)library_shared) will
fail the build.

This change:
1) Adds a test to reproduce the problem.
2) Improves the debug message by pretty printing the tag.
3) Adds a new ExcludeFromApexContents interface that can be implemented
   by a tag to declare that it should be excluded from the APEX
   contents.
4) Ignores tags that implement that interface when generating APEX
   contents.
5) Implements that interface on prebuiltDependencyTag to fix the
   test.

The DepIsInSameApex() and RequiredSdks() methods were defined in a few
places to avoid having to depend on the whole ApexModule/SdkAware
interfaces directly. However, that has a couple of issues:
1) It duplicates functionality making it difficult to change, changes
   to the definitions outside the main interfaces do not cause compile
   time failures, instead they result in a runtime change in behavior
   which can be difficult to debug.
2) IDE navigation (specifically in Intellij) does not detect that the
   duplicate definitions can resolve to the definitions in the main
   interface.

This change extracts the methods into their own interfaces and reuses
those interfaces instead of duplicating the methods to fix both of
these issues.

It was because unwinder is linked dynamically in R and APIs are provided

APIs. To make Q apexes run on Q device, libc++ should be linked with
static unwinder. But, because libc++ with static unwinder may cause problem
on HWASAN build, Q apexes were built against the latest stubs for bundled
build.

However, Q apexes should be built against Q stubs.

Now, only for HWASAN builds, Q apexes are built against the latest stubs
(and native modules are not linked with static unwinder).

Jiyong Park f760cae41b apexDepsMutator is a top-down mutator
apex { name: ["myapex"], native_shared_libs: ["libX", "libY"] }
cc_library { name: "libX", shared_libs: ["libY"] }
cc_library { name: "libY", shared_libs: ["libZ"], stubs: {...} }

apexDepsMutator was a bottom up mutator and it uses WalkDeps to traverse
the dependency tree rooted at myapex in a depth-first order. While
traversing the tree, if calls BuildForApex for a module that will be
part of the APEX.

libY is visited twice. Once via libX and once via myapex. If the visit
from libX was before the visit from myapex (since this is a depth-first
traversing), BuildForApex is not called for libY and its dependency
libZ, because libY provides a stub. And then when libY is again visited
via myapex, BuildForApex is correctly called for the module, but not for
its dependencies libZ because the paths from libY to libZ was already
visited.

As a result, the apex variant of libY has a dependency to the non-apex
variant of libZ.

Fixing the problem by changing the mutator a top-down one.

Jiyong Park 0f80c1848a apex_available tracks static dependencies
This change fixes a bug that apex_available is not enforced for static
dependencies. For example, a module with 'apex_available:
["//apex_available:platform"]' was able to be statically linked to any
APEX. This was happening because the check was done on the modules that
are actually installed to an APEX. Static dependencies of the modules
were not counted as they are not installed to the APEX as files.

Fixing this bug by doing the check by traversing the tree in the method
checkApexAvailability.

This change includes a few number of related changes:

1) DepIsInSameApex implementation for cc.Module was changed as well.
Previuosly, it returned false only when the dependency is actually a
stub variant of a lib. Now, it returns false when the dependency has one
or more stub variants. To understand why, we need to recall that when
there is a dependency to a lib having stubs, we actually create two
dependencies: to the non-stub variant and to the stub variant during the
DepsMutator phase. And later in the build action generation phase, we
choose one of them depending on the context. Also recall that an APEX
variant is created only when DepIsInSameApex returns true. Given these,
with the previous implementatin of DepIsInSameApex, we did create apex
variants of the non-stub variant of the dependency, while not creating
the apex variant for the stub variant. This is not right; we needlessly
created the apex variant. The extra apex variant has caused no harm so
far, but since the apex_available check became more correct, it actually
breaks the build. To fix the issue, we stop creating the APEX variant
both for non-stub and stub variants.

2) platform variant is created regardless of the apex_available value.
This is required for the case when a library X that provides stub is in
an APEX A and is configured to be available only for A. In that case,
libs in other APEX can't use the stub library since the stub library is
mutated only for apex A. By creating the platform variant for the stub
library, it can be used from outside as the default dependency variation
is set to the platform variant when creating the APEX variations.

3) The ApexAvailableWhitelist is added with the dependencies that were
revealed with this change.

Jiyong Park 3ff1699683 Create APEX variation only when needed
Create an APEX variation of a module only when it is either directly
included in an APEX or the dependency to the module demands that the
module should be included. For example, a non-static dependency to a
java library no longer creates an APEX variant of the library.

Jooyung Han 671f1ce75e Fix apex to follow deps of modules with stubs.
In case that an apex module depends on a module with stubs directly
*and* indirectly, the build system should follow the deps graph further.

Note that WalkDeps() visits deps in DFS and it won't visit again visited
modules.

Jiyong Park 505221f6e0 ignore apex_available for host variants
The main purpose of apex_available is to prevent a module from being
installed to the system partition (or being statically linked to
something that is installed to the system partition). It's not the goal
to prevent host tools from using the modules.

However, since both host and device variants are not mutated for
platform when the module is not available to platform, the host tools
that depends on those modules couldn't be built. To solve the problem,
the platform variation is NOT skipped for the host variants.
