* Explictly pass VerifierDeps when asking for class verification.Nicolas Geoffray2021-03-221-5/+7
| | | | | | | | | | This will simplify creating and populating VerifierDeps at runtime, which is needed for doing and saving background verifcation of secondary dex files. Test: test.py Bug: 158463186 Change-Id: Ic17913ebd173700e866ba9309bf6ae131fcbc423
* Disable the public SDK Checker during exception throwingCalin Juravle2021-01-211-0/+6
| | | | | | | | | | | | | | | | | | | The compiler will try to throw exception when it cannot resolved methods/classes or when there's an incompatible class change. While doing so, it requires the thrown exception class to be initialized. However, when verifying with a public SDK Checker installed, it's possible that the exception class may not initialized due to private member access (e.g. serialVersionUid). Since during verification the exceptions are simply mechanism for the compiler to propagate the verification error it is OK to disable the SDK Checker and allow the class to be initialized.

* SDK-stub controlled dex2oat verificationCalin Juravle2020-12-081-0/+19
| | | | | | | | | | | | | | | Allow dex2oat to further limit the resolved (boot classpath) symbols during verification according to an additional list of public SDK files. The additional SDKs can be specified as regular classpath (a list of dex files) and has the effect of limiting what can be resolved from the boot classpath. The extra checks are performed by comparing the symbol descriptors and do not replace common verification access-checks flow.

* Add a new class status for verified with access checks.Nicolas Geoffray2020-06-091-0/+3

* Fix boot image extension class exclusion.Vladimir Marko2019-11-251-0/+72
| | | | | | | | | | The code in CompilerDriver was too permissive for arrays and the code in Transaction was not even checking interfaces. Move the check to AotClassLinker and fix it.

* Load classes for boot image extension.Vladimir Marko2019-11-151-5/+18
| | | | | | | | | | | | Previously we actually failed to load and initialize classes for boot image extensions. Though some classes may have been resolved by other code paths, extension art files did not contain the intended classes. This CL fixes that and some other bugs that were exposed by this class initialization.

* Revert^2 "Optimize FindClass ClassNotFoundException case"Andreas Gampe2019-04-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | With the current class loaders, there are many exceptions thrown for each ClassNotFoundexception from FindClass calling ClassLoader.loadClass. This CL reduces that by throwing directly from FindClass to avoid these extra exceptions. Numbers are from logging time taken by QuickDeliverException. Time spent in exception throwing during startup goes down (Pixel 2 XL): Camera: 20ms -> 5ms Calculator: 5ms -> 2ms Maps: 20ms -> 10ms Added option -XX:FastClassNotFoundException=<bool> to enable or disable the feature. This reverts commit d399f579cf2a8462ef6f1fbea360fe62be174377.

* Change ClassStatus to fit into 4 bits.Vladimir Marko2018-01-051-3/+3
| | | | | | | | | | | | | | | | | In preparation for extending the type check bit string from 24 to 28 bits, rewrite ClassStatus to fit into 4 bits. Also perform a proper cleanup of the ClassStatus, i.e. change it to an enum class, remove the "Status" word from enumerator names, replace "Max" with "Last" in line with other enumerations and remove aliases from mirror::Class.

* Support class unloading in dex2oat for quicken multidexMathieu Chartier2017-08-081-2/+18
| | | | | | | | | | | | | | | | | Support class unloading for the quicken compilation filter. This will be enabled in a follow up CL. Added a test that compares with and without unloading. The way that it tests this is by adding an output app image. Having an app image disables the unloading. This test also covers that app images don't change the odex (currently). Added a test for the assumed verified logic. Bug: 63467744 Test: test-art-host Test: test/testrunner/testrunner.py --interpreter --host -j40 Change-Id: I1e8a862c6f089c06c58aa0c846797e4c24bd072c

* Support clinit for app image during compilationChang Xing2017-08-021-3/+19
| | | | | | | | | | | | | | | | | | | | Enabled compiler driver to start initialization process for classes with static class initializers if debuggable flag is not setted because this might change the behaviour of interpreter (although invisible to user), e.g. the memory heap at startup will contains initialization results. Updated two testcases to reflect the change of heap memory before classes are initialized. Enabled testcase 660-clinit to test whether class initializers are executed. This CL have to be submitted after /c/432328, /c/432154, /c/433242 and /c/433342 because without that four this will break the build. Besides, the other four CL will be tested in this CL.

* Fix recursive initialization on app image.Chang Xing2017-07-291-2/+13
| | | | | | | | | | | | | | | | | | Assume class B extends class A and class A's clinit tries to instantiate class B as a field. In this case, class A is under initializing but ClassLinker allows initialize B as class A is initialized. If class B is initialized successfully and transaction is commited then class A abort the transaction, status of class B will not be reverted. Fixed by a simple approach, when compiling images, AotClassLinker does not allow initialize a subclass when it's superclass is not fully initialized. A testcase produce this error is added in /c/433381 Test: make test-art-host -j64 Change-Id: Ic6bcbf1a5162d0e6ec26979b336c0f644a1c39bc
* Implemented Nested TransactionChang Xing2017-07-261-0/+58
Transaction can be created recursively and every transaction knows which class it is created for. The goal of implementing nested transaction is to let every class initialization (especially execution of class initializer) associates with one transaction which provides the ability to track whether field accesses are valid. To achieve this goal, we implemented a subclass for ClassLinker called AotClassLinker, which will be instantiated instead of ClassLinker under AOT compiler. All invocations of InitializeClass happens at AOT compiler will be wrapped with creating and destorying transactions. Transactions will be paused when rollbacking, otherwise the memory will not be rollbacked properly. The use the transaction is changed and all usage are updated, corresponding with native tests mentioning transaction, including transaction_test and unstarted_runtime_test. The validation rules will be implemented and explained in another CL. Test: make test-art-host -j64 Change-Id: If53d3ee3231c337a9ea917f5b885c173917765de
