1822a0a371 Improve sdk snapshot testing
The sdk produces snapshots that are expected to be unpacked in one of
the Android repos. Often that can lead to issues due to conflicts
between the source and prebuilts. This change attempts to avoid those
conflicts by testing the different ways that those files can be used.

With the existing test to cover adding the snapshot
This change will cause the sdk tests to check the following:
1) Snapshot on its own (already done).
2) Snapshot plus original source where the original source is
   preferred.
3) Snapshot plus original source where the snapshot is preferred.

It also adds the ability for tests to provide their own custom checkers
to verify the result of each of the previous tests.

This change reveals a number of bugs already present. Rather than
attempt to fix them this change adds the ability to specify error
handlers for the two cases that mix source and snapshot to allow those
errors to be temporarily ignored while allowing the majority of the
tests to benefit from this improvement. Each of those failures has a
TODO and bug associated with it.

4c3e8e2d67 Ensure that DepIsInSameApex is not called for ExcludeFromApexContentsTag
The ExcludeFromApexContentsTag marker interface was added to avoid
every implementation of DepIsInSameApex() from having to deal with the
special tags, like PrebuiltDepTag. Unfortunately, when adding that
not all calls to DepIsInSameApex() were protected which meant that the
BootImageModule, which panics if it doesn't recognize a tag, was
causing failures. This change documents the need and improves the
consistency.

A follow up change will add a test for this.

573989d821 Prevent ApexInfoMutator from creating unnecessary variants
Adds the AlwaysRequireApexVariantTag interface to enable
ApexInfoMutator to differentiate between a tag that is excluded from
apex contents but still requires an apex variant and a tag that is
excluded from apex contents and does not require an apex variant.

That is needed to support the sdkMemberVersionedDepTag which excludes
the target from being added to the APEX but requires an APEX variant.
A more detailed explanation is in the comments.

The AlwaysRequireApexVariant() method follows the pattern used in
ReplaceSourceWithPrebuilt of having a method that returns a bool to
trigger the behavior and not say ExcludeFromApexContentsTag that simply
relies on the tag implementing an interface to trigger. That is because
the former is more flexible and allows a tag type to parameterize the
behavior if necessary.

The tags that this will exclude from creating an apex variant are:
* PrebuiltDepTag - by the time the apex variant has been created any
  preferred prebuilts will have replaced the sources so there is no
  need to create an APEX variant if the only dependency path from the
  APEX to the prebuilt is via this tag.
* hiddenApiAnnotationsDependencyTag - the target of which is a purely
  build time artifect and MUST NEVER end up in the APEX.

It will also stop calling DepIsInSameApex for any dependency created
by the sdkMemberVersionedDepTag. Which will fix the issue reported in
the bug.

157f40f056 Add prebuilt_visibility property
Some mainline modules provide an `sdk` and one or more set of
module_exports. When the snapshots are unpacked into separate prebuilts
directories (one per snapshot) then any dependencies from a member of
one snapshot to a member of another may require the latter to have
additional visibility rules.

Previously, these rules had to be added to each source module. This
change allows additional visibility rules to be specified on the
sdk/module_exports that are added to all the prebuilts in its snapshot.

a37eca27c8 Avoid creating APEX variant for sdk member
Previously, an APEX variant was created for a module that was a member
of an SDK just in case it had to be replaced with an APEX requested
snapshotted version of that member. That was necessary because that was
the only way to have APEX specific replacements.

Since then a new method called ReplaceDependenciesIf() has been added
which provides fine grained control over which dependencies are
replaced. This change uses that new method to handle the replacements
which allows the APEX variants to be removed.

6534770793 Stop requiring apex_available on java_library members of sdks
Previously, adding java_library to an sdk required that the names of
any APEXes that transitively compiled against it were added to its
apex_available property. This change removes that requirement.

Also corrects the dependency path in the TestApexAvailable_IndirectDep
error which previously passed through "shared from static" static
dependency tags even though those are explicitly NOT followed when

923e8a5e9e Extract DepIsInSameApex and RequiredSdks interfaces
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.

6a7e953e62 Sdk snapshot set compile_multilib per OsType
Previously, when an sdk snapshot only supported a single os type the
compile_multilib was set based on the multilib usages by the members
of that variant. After the change to support multiple os types per
snapshot the multilib setting was based on the multilib usages across
all the members of all sdk variants. That meant that if one os type
used only "64" and the other used "both" then they would both be
treated as "both" leading to missing variants when the snapshot was
unpacked.

This change tracks the multilib usages per os type and adds a property
for each one.

It intentionally changes a couple of tests:
1) Either by adding compile_multilib that is missing.
2) By targeting it at a specific os type instead of host.

The latter change is important to prevent the snapshot from being
used on a host platform (which will match the host target section)
but which is a different os type to the ones supported by the
snapshot.

This change ensures that the runtime dependencies between a
binary/shared library are correctly specified in the snapshot so that
the build can ensure that shared libraries are built before the targets
that use them.

It adds support for differentiating between references that are
required to refer to another sdk member (required) and those that may
refer to either an sdk member or a non-sdk member (optional). The
latter is used for shared library references as the libraries used by
an sdk member may be provided from outside the sdk. e.g. liblog is not
part of the ART module but is used by some members of the ART sdk.

1356d8c0f3 Add CommonOS variant for sdk
Adds a CommonOS variant for sdk that depends on the os specific
variants and is used to generate a single sdk for multiple OsTypes,
e.g. host linux and android.

At the minute the member types only support a single OsType but the
basic mechanism for managing the CommonOS variant and collating the
variants across all of them is there.

The only visible effect of this change is that the location of the
generated snapshot is changed, it is no longer os specific and instead
is in the same location irrespective of which os it is built for.

A lot of tests needed to be changed to specify "common_os" as the
variant type instead of the specific os type. As that is the same across
all tests it is hard coded in CheckSnapshot method.

add dependencies on corresponding sdk member variants as if those
variants have not been created then the build breaks unnecessarily.

This is needed to make progress on unbundling art which provides at
least one host tool (dex2oat) that is not supported on all platforms
and some (hiddenapi) that only produce 64 bit versions.
Initially, the art prebuilts will only support building 64 bit

7291095d82 Differentiate between exported and internal sdk members
Internal sdk members are used by an sdk member but not exported by the
sdk. The exported sdk members are those listed explicitly in one of the
sdk member list properties, e.g. java_header_libs.

The prebuilts of an internal sdk member use a unique name so that they
do not clash with the source module. The use of the module internally
is an implementation detail that must not have any effect outside the
snapshot. Having the same name as the source module could cause it to
override the source module, hence why it needs a unique name.

Similarly, they are marked as private so as to prevent their accidental
use from outside the snapshot.

255f18e584 Decouple addition of new sdk member types from sdk code
Previously, adding a new SdkMemberType would require adding a new
sdkMemberListProperty instance to the sdkMemberListProperties as well
as adding a new property into the sdkProperties struct. They are
potential sources of conflict and couple the sdk code with all the
packages that add members to it. This change switched to a
registration model that allows each package to register its sdk
member types decoupling them from the sdk code.

Adds an SdkPropertyName() method to SdkMemberType that specifies the
name of the property to use in the sdk/sdk_snapshot. Also provides
an SdkMemberTypeBase struct to be used by providers of SdkMemberType
implementations.

SdkMemberType instances are registered using the
RegisterSdkMemberType() func which sorts the registered instances
by their SdkPropertyName() to ensure the behavior is consistent and
not affected by order of registration.

When creating a new sdk module a dynamicSdkMemberTypes instance is
created that contains the following:

* A properties struct is created dynamically that contains a field for
  each registered SdkMemberType, corresponding to that type's
  SdkPropertyName().

* A list of sdkMemberListProperty instances is also created, one for
  each registered SdkMemberType.

The dynamicSdkMemberTypes instance is cached using a key that uniquely
identifies the set of registered types just in case new types are
registered after one has been created, e.g. by tests.

methods of that type.

1387957727 Parameterize the sdk member processing
Extracts the type specific functionality into the SdkMemberType
interface which has to be implemented by each module type that can
be added as a member of the sdk. It provides functionality to add
the required dependencies for the module type, check to see if a
resolved module is the correct instance and build the snapshot.

The latter was previously part of SdkAware but was moved because
it has to be able to process multiple SdkAware variants so delegating
it to a single instance did not make sense.

The custom code for handling each member type specific property,
e.g. java_libs, has been replaced with common code that processes
a list of sdkMemberListProperty struct which associates the
property (name and getter) with the SdkMemberType and a special
DependencyTag which is passed to the SdkMemberType when it has to add
dependencies.

The DependencyTag contains a reference to the appropriate
sdkMemberListProperty which allows the resolved dependencies to be
grouped by type.

Previously, the dependency collection methods would ignore a module if
it was an unsupported type because they did not have a way of
determining which property it was initially listed in. That meant it
was possible to add say a droidstubs module to the java_libs property
(and because they had the same variants) it would work as if it was
added to the stubs_sources property. Or alternatively, a module of an
unsupported type could be added to any property and it would just be
ignored.

However, the DependencyTag provides information about which property
a resolved module was referenced in and so it can detect when the
resolved module is of the wrong type and report an error. That check
identified a bug in one of the tests where the sdk referenced a
java_import module (which is not allowed in an sdk) instead of a
java_library module (which is allowed). That test was fixed as part
of this.

A list of sdkMemberListProperty structs defines the member properties
supported by the sdk and are processed in order to ensure consistent
behaviour.

The resolved dependencies are grouped by type and each group is then
processed in defined order. Within each type dependencies are grouped
by name and encapsulated behind an SdkMember interface which includes
the name and the list of variants.

The Droidstubs and java.Library types can only support one variant and
will fail if given more.

The processing for the native_shared_libs property has been moved into
the cc/library.go file so the sdk package code should now have no type
specific information in it apart from what is if the list of
sdkMemberListProperty structs.

the snapshot directory java/foo/stubs then it will create a zip that
contains java/foo/stubs/foo/Foo.java.

The temporary zip that is the output of that rule is added to the
zipsToMerge field for merging later.

If the zipsToMerge is empty then the snapshot zip is created as
before. Otherwise, a temporary zip file is created. That is then
merged with the other zip files in zipsToMerge to create the final
snapshot zip.

Adds prebuilt_stubs_sources for use by the generated .bp module.

232e785b98 SDK snapshot is dist'ed
`m module_sdk dist` produces snapshots of all SDKs in the source tree.
A snapshot is a zip file consists of Android.bp, exported headers,
exported AIDL files, stubs for native libs and jars. The zip file is
expected to be downloaded from the build server and extracted to a
directory (which probably will be
/prebuilts/module_sdks/<module_name>/current).

73c54ee7fe native shared libs in an SDK can be snapshotted
The snapshot script can now handle native shared libs in an SDK.

Bug: 138182343
Test: create following sdk module:
sdk {
    name: "mysdk",
    native_shared_libs: ["libc", "libdl"],
}
, then execute `m mysdk` and execute the update_prebuilt-1.sh as
prompted. Following directories are generated under the directory where
mysdk is defined at:

the outside of the APEX should be from the SDKs that the APEX is built
against.

0f7d2ef3ac Add method to determine variations from a Target

them out into a Target.Variations() method in preparation for
splitting the arch mutator into two, which will require using
different variations.

9b409bcd10 Create scripts to update and freeze a module SDK
`m <sdk_name>` generates two scripts each of which is use to update the
current snapshot of the SDK and to freeze ToT as a new version,
respectively. Executing the scripts will copy necessary files (stub
libraries, AIDL files, etc.) along with Android.bp into the ./<apiver>
directory under the directory where the sdk is defined.

This change also introduces a new module type 'sdk_snapshot' that
represents a snapshot of an SDK. It will be auto-generated by the above
scripts, so developers are not expected to write this manually.

The module type 'sdk' is now used to simply specify the list of modules
that an SDK has.

Finally, this change changes the version separator from '#' to '@'
because '#' confuses Make.

d1063c1586 Introduce module type 'sdk'
This change introduces a new module type named 'sdk'. It is a logical
group of prebuilt modules that together provide a context (e.g. APIs)
in which Mainline modules (such as APEXes) are built.

A prebuilt module (e.g. java_import) can join an sdk by adding it to the
sdk module as shown below:

sdk {
    name: "mysdk#20",
    java_libs: ["myjavalib_mysdk_20"],
}

java_import {
    name: "myjavalib_mysdk_20",
    srcs: ["myjavalib-v20.jar"],
    sdk_member_name: "myjavalib",
}

sdk {
    name: "mysdk#21",
    java_libs: ["myjavalib_mysdk_21"],
}

java_import {
    name: "myjavalib_mysdk_21",
    srcs: ["myjavalib-v21.jar"],
    sdk_member_name: "myjavalib",
}

java_library {
    name: "myjavalib",
    srcs: ["**/*/*.java"],
}

An APEX can specify the SDK(s) that it wants to build with via the new
'uses_sdks' property.

apex {
    name: "myapex",
    java_libs: ["libX", "libY"],
    uses_sdks: ["mysdk#20"],
}

With this, libX, libY, and their transitive dependencies are all built
with the version 20 of myjavalib (the first java_import module) instead
of the other one (which is for version 21) and java_library having the
same name (which is for ToT).
