2021-09-27Add newStringFromUtf8Bytes native implementation.Rock.Yeh
Porting a part of StringFactory.newStringFromBytes from libcore to native for UTF-8 character set. It can improve the UX score of Antutu v8 a little bit. Only watch UX score. We test 10 times and average the total score. Bechmark results - before(Java implementation): 10 times avg,: 13133.9 - after (Native implementation): 10 times avg.: 13324.2 Diff.: +1.4% Bug: 176514597 Test: cts Change-Id: I6b601c09663b21fdacde7f14b0db1ac4f0a94c0f

2020-03-13Reland "libcore: Remove native calls in FileDescriptor <clinit>"Orion Hodson
This reverts commit Ie9fa5a25d5352f214a16e10d5bbbe45da9f3c486. Original commit message: Moves cloning of FileDescriptor in, out, and err descriptors into a ZygoteHook. This avoids the need to run JNI methods in FileDescriptor.<clinit> and enables native Core Platform API checking of FileDescriptor descriptor and ownerId fields. Changes in reland: Force UnixChannelFactory to fail initialization during AOT compilation. UnixChannelFactory is on the preloaded-classes-blacklist and the changes in the original CL unintentionally allowed it to be initialized. It used to be that FileDescriptor and UnixChannelFactory initialization failed in the same transaction due to the FileDescriptor clinit method making native calls (dup(s)).

New annotation is tools/platform-compat/annotation/src/java/android/compat/annotation/UnsupportedAppUsage.java.

2019-03-12Merge "Allow size for malloc-only registration"Hans Boehm
2019-03-12Allow size for malloc-only registrationHans Boehm
Encode malloc-only allocations with an odd size field. These are treated similarly to the prior treatment of zero size objects, except that: - Huge allocations cause more frequent mallinfo() checks. - The sizes are stored, and hence available to ahat and friends. Add public factory methods to hide the negative size representation and provide a slightly easier-to-describe-and-use API. Add registerNativeAllocation(long) and registerNativeFree(long) methods to VMRuntime to avoid enshrining the obsolete ones in the platform API. Unfortunately we need to retain the old ones for compatibility, at least for now. See also ag/6235934 . Bug: 121304803 Test: build and boot AOSP Change-Id: Idccb8b50d26c8c3e93cc34040d784f74dfcdbf51

2019-02-18Blacklist VMRuntime.setTargetSdkVersion()David Brazdil
Enabling apps to overwrite their target SDK version in the runtime is undersirable as it may allow them to access APIs in greylists intended for legacy apps only, e.g. an app targeting Q accessing greylist-max-o. Move the setter in VMRuntime to blacklist. API usage data shows very limited affect of this change. Test: n/a Change-Id: I52de53c208894fae15edde19a92efb60f86100f0
2019-02-11Mark threads started by Daemons.java as systemDaemonAlex Light
The threads started by Daemons.java are special daemon threads that provide important GC related functionality to the runtime. As such the runtime sometimes needs to keep track of which threads these are. This adds support for keeping track of that data. Also give a way for the runtime to wait for all Daemon threads to come up. Test: while atest CtsJdwpTestCases; do; done; Exempt-From-Owner-Approval: Previous version approved by nfuller@ with only minor nit changes.

5c9406fb hardcoded "linux" as the value for the os.name property on Android. Because we will now support additional device OSs, this value is no longer static. Reverting back to dynamically querying os.name will regress compile-time initialization for AbstractDatagramSocket. Analysis of this is tracked in b/121268567.

2018-12-12Adjust NativeAllocationRegistry for new accountingHans Boehm
Provide a new NativeAllocationRegistry constructor that does not require a size, assuming instead that all native allocation goes through malloc() and the GC tracks native allocation anyway. Use it in BigInt, Pattern, and Matcher, the traditional problem cases for proper size tracking. We should use it in many other cases as well. The fact that we're not yet doing so has the effect that we're currently double-counting some allocations. However a mere factor of 2 error is likely to be a huge improvement already over prior accounting. Force the argument to setTargetHeapUtilization to be at least 0.1. Very small numbers are not reasonable, and could cause overflows in ART. (Needed by accounting cleanups in the companion ART CL.)

2018-12-03Add fields to ClassExt to store pre-redefine DexFile pointerDavid Brazdil
Hidden API access checks refer to the dex file of a class to read the access flags of a given method/field. The pointer to the dex file is lost when the class is redefined with JVMTI.

Additional libcore classes and methods have been added to the hiddenapi since the last time stubs were added. This change adds stubs and annotations for them all.

Metalava was accidentally including default constructors in the API generated for CorePlatformApi and IntraCoreApi annotations. This change adds the constructor and appropriate annotations to allow the metalava bug to be fixed without changing the API. Tested by building the API with and without the Metalava fix and checking that they were the same apart from removing the constructors for the following classes as they are not required in the API because the classes are never meant to be instantiated: * dalvik.system.VMSTack * libcore.icu.ICU * libcore.io.DropBox * libcore.io.EventLogger * libcore.net.MimeUtils * libcore.util.SneakyThrow Bug: 119859108 Test: see above Change-Id: I87cdb60827edbc2703b9b8723e873aa49c82d9cf
