2025-03-20Move more path logic for tests to testing.cc, so it can be used without Martin Stjernholm
depending on CommonArtTest. Preparation to fix the libart-gtest dependency in art_standalone_libartpalette_tests. Due to a new #include, this necessitated fixing a bunch of `testing` namespace references that could become ambigious wrt `art::testing`.

2024-09-10Restrict exported symbols from libnative{loader,bridge} lazy libs. Martin Stjernholm
The shims in the lazy libs bypass the stubs and hence the vetted exported APIs in the .map.txt files. To avoid inadvertently giving external access to internal APIs that way, let's apply the .map.txt files as version scripts to the lazy libs instead, so that any functions added there just don't become available to external code unless the .map.txt files get updated. This hack doesn't work if the lazy libs are linked statically, so restrict them to be shared libs (although ideally they should be static instead to avoid the shared lib overheads). Also drop the shims for the two functions added in https://r.android.com/2689969 and https://r.android.com/3022103, because they're only used internally in ART and don't go through the shims.

2024-08-13Simplify test configs by disabling append-bitness and pushing the whole Martin Stjernholm
test directory instead. Using append-bitness with FilePusher apparently disables pushing of the whole directory. If we remove it and push the test directory instead, we won't need to append bitness since it's added implicitly (and the test directory also has arch subdirectories). Without append-bitness we can also switch to PushFilePreparer, because that flag is the only difference between them. By pushing the whole test directory it's possible to clean up several cases where it was necessary to push other files with the tests. Test configs that invoke generate-boot-image on the device aren't so easy to fix this way, because we must expand the right path to the binary inside the test directory. Hence they're kept as-is for now. #codehealth Test: atest -a art_libnativebridge_cts_tests art_standalone_artd_tests \ art_standalone_cmdline_tests art_standalone_compiler_tests \ art_standalone_dex2oat_cts_tests art_standalone_dex2oat_tests \ art_standalone_dexdump_tests art_standalone_dexlist_tests \ art_standalone_dexopt_chroot_setup_tests \ art_standalone_dexoptanalyzer_tests art_standalone_dexpreopt_tests \ art_standalone_disassembler_tests art_standalone_libartbase_tests \ art_standalone_libartpalette_tests \ art_standalone_libartservice_tests art_standalone_libarttools_tests \ art_standalone_libdexfile_external_tests \ art_standalone_libdexfile_support_tests \ art_standalone_libdexfile_tests art_standalone_libprofile_tests \ art_standalone_oatdump_tests art_standalone_odrefresh_tests \ art_standalone_profman_tests art_standalone_runtime_tests \ art_standalone_sigchain_tests libnativeloader_lazy_test \ libnativeloader_test libnativebridge-tests Change-Id: I7c524a856821a5ee2b53d53e84793bf6527b970b
2024-08-12Link libraries with unstable ABIs statically into libnativebridge-tests. Martin Stjernholm
It incorrectly used art_test_internal_library_defaults, which requires setting NATIVELOADER_DEFAULT_NAMESPACE_LIBS to work. It still links several test libraries dynamically, but that works fine since they're pushed with the test. Add a test config to enable pushing the test libraries. It's the same as art-gtests-target-standalone-template.xml, except `append-bitness` isn't passed to the file pusher, which apparently disables pushing the whole test directory.

2024-05-15Use isolated: true instead of test_per_src: true in libnativebridge_tests Colin Cross
libnativebridge_tests uses test_per_src: true to avoid running multiple tests in the same process. gtest_isolated uses separate processes for each test, but without the various incompatibilities caused by test_per_src. Switch to isolated: true instead. Create a temporary directory in the constructor of the shared NativeBridgeTest base class instead and put the code_cache directory inside it to keep the tests from trying to modify the current directory.

2024-03-18Revert "libnativebridge_test: link non-public libs statically" and fix Martin Stjernholm
the CTS test to only call exported APIs. Reverts commit 7f5b3d89f21edd958ddb9d7bd01e03c77bd5425a. CTS tests need to link the libraries they test dynamically, and this test only tests exported stable APIs. The standalone CTS test config template includes NativeBridgeModuleController, so the test won't run in a translated environment (which has no proxy for this library and hence caused the error that prompted commit 7f5b3d89f21edd958ddb9d7bd01e03c77bd5425a). The test also used to test some non-exported APIs, which it shouldn't do in CTS. This changes it to use art_standalone_test_defaults, which doesn't have the test_for attributes that made it bypass the stub. Also reuse the trivial API-only tests for libnativebridge_lazy, and give them a more apt name for the new use.

2023-03-16Make art modules apex_available to test_broken_com.android.art Cole Faust
libart-broken needs to compile against the source of its dependencies, not stubs. The stubs/source logic is complicated, but one of the ways it can be affected is that if both modules have identical apex_available lists, they will be allowed to depend on the source of each other. libart-broken needs to be apex_available to test_broken_com.android.art, so test_broken_com.android.art needs to be added to libdexfile as well. This change then propagates virally though most of the art modules. This is needed now because we're making a change to allow building the non-apex variants of apex dependencies. The apex variant of libart-broken did not have this issue because the stubs/source rules are different for apex variants.

2022-10-01Annotate symbols correctly Jiyong Park
Currently, tagging a symbol with #apex (# systemapi or # llndk) is not required when the symbol is in a non-NDK library. However, this is considered dangerous because such a symbol will automatically be promoted to NDK APIs when the library is promoted to an NDK library. When that happens, the native API council won't be able to notice the promotion because promoting a non-NDK library into an NDK library doesn't require an update of the map.txt file, but Android.bp only. To prevent that, we should mandate those tags for Mainline APIs regardless of whether the library the API belongs to is an NDK library or not. Upcoming changes in build/soong will enforce this. This change is to prepare for the enforcement. Note that this is a build-time only change. There's no behavior change at runtime.

2021-05-10Avoid loading external libraries from ARTs internal linker namespace Martin Stjernholm
(reland). dlopen() calls in ART will use its own linker namespace (com_android_art). That's appropriate for internal libraries in the APEX, but not when ART loads libraries on behalf of external requests. In those cases we should instead use android_dlopen_ext to load them from the system namespace, i.e. the one that searches /system/lib(64). The linker config has been using allow_all_shared_libs, so any loads from com_android_art fall back to the system namespace, and hence dlopen() usually works regardless which namespace it ought to use. However we want to drop allow_all_shared_libs, so we need to figure out which dlopen's should use which namespace: 1. Several ART libraries are loaded on-demand, e.g. libart-compiler and libart-disassembler. There are also those going through the runtime plugin system, like libperfetto_hprofd and heapprofd_client_api. All these are internal or at least statically known (so we can provide links for them in the linker config), and should continue to use dlopen from the ART namespace. 2. libnativeloader loads the preloadable public libraries from system/etc/public.libraries.txt, and should use the system namespace for that. 3. libnativebridge loads the native bridge implementation specified through the command line (or ultimately the system property ro.dalvik.vm.native.bridge). It's not part of the ART APEX and not known statically, so the system namespace should be used. 4. libnativeloader also loads JNI libraries from classloader namespaces, but has a fallback if no such namespace can be found based on caller location. Fall back to the system namespace to handle libraries loaded during the preload phase in the zygote. 5. JVMTI agents are loaded by dalvik.system.VMDebug.attachAgent(). Treat these too as external libraries - they are loaded in a way similar to JNI libraries through OpenNativeLibrary in libnativeloader, so are covered by #4. They are normally loaded by apps with a classloader, but a special case is adbconnection which loads libjdwp.so in the ART APEX without one and hence falls back to the system namespace. We therefore need to create a link for it (https://r.android.com/1690889, https://r.android.com/1690795). All cases #2-#5 are covered by libnativeloader and libnativebridge. Introduce OpenSystemLibrary, and since libnativeloader depends on libnativebridge, put it in the latter to be usable from both. It's only an internal dependency not exposed in the APEX stubs. (Another possibility could be to put it in the generic toolbox lib libartbase, but it's split into -d and non-d variants, and we don't want to split libnative{loader,bridge} that way.) Since libnativeloader_test no longer needs to mock dlopen we can simplify it to a more regular test that loads the tested libs dynamically. This relands https://r.android.com/1673312 without setting ANDROID_ADDITIONAL_PUBLIC_LIBRARIES in run-test-jar, because that made libnativeloader try to preload internal libraries from the system namespace.

2021-05-07Avoid loading external libraries from ARTs internal linker namespace. Martin Stjernholm
dlopen() calls in ART will use its own linker namespace (com_android_art). That's appropriate for internal libraries in the APEX, but not when ART loads libraries on behalf of external requests. In those cases we should instead use android_dlopen_ext to load them from the system namespace, i.e. the one that searches /system/lib(64). The linker config has been using allow_all_shared_libs, so any loads from com_android_art fall back to the system namespace, and hence dlopen() usually works regardless which namespace it ought to use. However we want to drop allow_all_shared_libs, so we need to figure out which dlopen's should use which namespace: 1. Several ART libraries are loaded on-demand, e.g. libart-compiler and libart-disassembler. There are also those going through the runtime plugin system, like libperfetto_hprofd and heapprofd_client_api. All these are internal or at least statically known (so we can provide links for them in the linker config), and should continue to use dlopen from the ART namespace. 2. libnativeloader loads the preloadable public libraries from system/etc/public.libraries.txt, and should use the system namespace for that. 3. libnativebridge loads the native bridge implementation specified through the command line (or ultimately the system property ro.dalvik.vm.native.bridge). It's not part of the ART APEX and not known statically, so the system namespace should be used. 4. libnativeloader also loads JNI libraries from classloader namespaces, but has a fallback if no such namespace can be found based on caller location. Fall back to the system namespace to handle libraries loaded during the preload phase in the zygote. 5. JVMTI agents are loaded by dalvik.system.VMDebug.attachAgent(). Treat these too as external libraries - they are loaded in a way similar to JNI libraries through OpenNativeLibrary in libnativeloader, so are covered by #4. They are normally loaded by apps with a classloader, but a special case is adbconnection which loads libjdwp.so in the ART APEX without one and hence falls back to the system namespace. We therefore need to create a link for it (https://r.android.com/1690889, https://r.android.com/1690795). All cases #2-#5 are covered by libnativeloader and libnativebridge. Introduce OpenSystemLibrary, and since libnativeloader depends on libnativebridge, put it in the latter to be usable from both. It's only an internal dependency not exposed in the APEX stubs. (Another possibility could be to put it in the generic toolbox lib libartbase, but it's split into -d and non-d variants, and we don't want to split libnative{loader,bridge} that way.) Since libnativeloader_test no longer needs to mock dlopen we can simplify it to a more regular test that loads the tested libs dynamically.
