2018-01-03ART: Clean up library loading Andreas Gampe
Retrieve the library path from the classloader before attempting to load, instead of getting it passed down. This allows unifying said loading behavior for follow-up changes. Fix up test code to support the new required data in classloader objects. Bug: 70901841 Test: m test-art-host Test: device boots Change-Id: Iaccaeb56422877abac9f7fe6f5a17364c8adf4ca

2017-12-22Extensions to check JNI. Ian Rogers
Ensure critical lock isn't held when returning from a down-call. Log a warning if the critical lock is held for a significant period of time. Refactor JNIEnvExt to be a class rather than a struct. Test: mma test-art-host Change-Id: I4d149cb04d3a7308a22b92b196e51e2f1ae17ede

2017-10-04ART: Add allocation tracking to JNI global refs Andreas Gampe
Add allocation tracking to global references. When the reference table's free capacity falls under an adjustable value, enable tracking so as to help tracking down possibly-leaky allocations. Bug: 67044702 Test: m test-art-host Change-Id: Ic17d6ebbad895b54c5ac63558027e04aef2b14c1
2017-09-25ART: Refactor IRT:Add Andreas Gampe
Do not abort on overflow. Return null and an error message. The caller is responsible for handling this, e.g., by aborting. In a future CL, this may be used for driving additional GCs. Additional side effect is the removal of a frame from an abortion stack trace. Test: m Test: m test-art-host Change-Id: I80b1e0ee396fc69906d051f1b661d7dba222fc6f
2017-09-19ART: Improve double-JNI-load exception message Andreas Gampe
Try to print the involved classloaders. The code is suboptimal and will not cache any intermediates, as this is an unexpected failure - but aids in debugging application issues. Add a test for the behavior of duplicate library loading in separate classloaders. For ART, add a rough test for the pattern of the error message.

2017-06-02Avoid holding mutator lock while calling dlsym Mathieu Chartier
Paranoid that dlsym might not always terminate quickly. The fix is to go to suspended before calling FindNativeMethodInternal. Bug: 62235781 Test: test-art-host Change-Id: I4323b580ffb582521ce94d8c90476e6db12bfe4a
2017-06-02ART: Introduce thread-current-inl.h Andreas Gampe
Factor out Thread::Current() code into its own -inl file to remove transitive includes. This requires at the same time correcting mutex.h, i.e., moving some functions into mutex-inl.h. Test: m test-art-host Change-Id: I88f888b604e0897368d9b483edce6ce4332dd9c9
2017-05-30ART: Clean up heap headers Andreas Gampe
Use more forward declarations for accounting structures and spaces. Factor out structs to reduce header surface. Remove heap include where unnecessary. Fix up transitive users. Move some debug-only code out of line. Test: m test-art-host Change-Id: I16db4aaa803f39e155ce6e1b0778b7e393dcbb17
2017-04-21ART: Clean up art_method.h Andreas Gampe
Clean up the header. Fix up other headers including the -inl file, in an effort to prune the include graph. Fix broken transitive includes by making includes explicit.

2017-04-20Agent libraries need to be searched for JNI functions Alex Light
This makes agent libraries the option of last resort for native method implementations. This will allow one to not need to manually link all native methods in an agent library. Bug: 37522517 Bug: 37432636 Test: ./test.py --host -j40 Change-Id: I5ad78a15e7e2799d2a877c5d603342899e2a1bd1

2017-03-18Revert "Make sigchain actually own the signal chain." Jin Qian
This reverts commit 7600fa9234e02cf5108a3a82babf3d3ab82fcddd. Change-Id: Ia46db2a7df0c0ac07107a8db06f42ff1afd4a97e
2017-03-17Make sigchain actually own the signal chain. Josh Gao
sigchain exists to make sure that art's signal handler is at the front, but it currently does this by putting the fault manager in the actual signal handler slot and having that handler call into sigchain when it doesn't want to handle a signal. sigchain also has a "special signal handler" (used for native bridge) that runs before user handlers, but after ART's. Move maintenance of the signal chain into sigchain itself, and use the same mechanism to handle the ART handler and the native bridge handler. Also, clean up some bugs: - InvokeUserSignalHandler was using the wrapper sigprocmask instead of the actual one. - Use SIG_SETMASK instead of SIG_BLOCK between calling handlers, in case one of the handlers changes the signal mask. - Correctly handle sigaction without SA_SIGINFO.

2017-02-10Fix the empty checkpoint timeout. Hiroshi Yamauchi
The problem happens when a thread is indirectly blocked on a mutex that another thread holds and is blocked on a weak ref access. Add a way to do a dummy wakeup on a thread that's blocked on a mutex so that the thread will respond to the empty checkpoint request. Do this for the mutexes that are expected to be held when a weak ref is accessed. Add a check that detects an unexpected case. Bug: 33006388 Bug: 12687968 Test: test-art-host. Change-Id: Iefec69b9a21aa25a928cb31fcf4fb872f867a8c2
2017-01-06Don't need to block in AddWeakGlobalRef and MonitorList::Add under CC. Hiroshi Yamauchi
CMS needs this to block because an object allocated during the GC won't be marked and concurrent reference processing would incorrectly clear the JNI weak ref or the monitor list weak. But CC doesn't because of the to-space invariant, that is, when a mutator tries to create a JNI weak ref or a monitor for an object, it must be already marked and the concurrent reference processing wouldn't incorrectly clear it. Bug: 34128900 Bug: 12687968 Test: test-art-host with CC. Change-Id: Ia87bf8ed9e604900df5ecb450c89b0ac222bef32

2016-10-24ART: Make IndirectReferenceTable resizable Andreas Gampe
Allow backing table to be resized. This can be used for the local reference table, where synchronization is not an issue. Bug: 32125344 Test: m test-art-host Change-Id: Iae3a933e330026231b17fdde44bcdd99c235dff1
2016-10-24ART: Change IndirectReferenceTable Andreas Gampe
Change cookie structure to allow for more entries. Use a local hole-count caching scheme. The design is driven by two considerations. For one, the change is small and mostly local. The other point is to still allow inlining of functions involved with JNI transitions. This change is in preparation for a resizable backing table for "unlimite" local references. micro_native tests show changes are in the noise.

2016-10-24ART: Clean up IndirectReferenceTable Andreas Gampe
Introduce constants and move some functions into the IndirectReferenceTable class. Slightly change IndirectRef encoding to be more obvious (and slighly more optimized when decoding). Bug: 32125344 Test: m test-art-host Change-Id: I05819eccb733b611de582fb8d7151f1a110c305a
2016-10-24Always call into native loader when loading a native library Zhenhua WANG
Namespace semantic has been enabled at native bridge side. And, native loader wraps both dynamic linker and native bridge. ART on longer calls native bridge directly when it loads a native library, but still remembers whether native bridge is needed for each library.

2016-10-20Merge "Return error message if IndirectReferenceTable construction fails." Treehugger Robot
2016-10-19Merge "Remove mirror:: and ArtMethod deps in utils.{h,cc}" David Sehr
2016-10-19Return error message if IndirectReferenceTable construction fails. Richard Uhler
Previously if there was an error when constructing the IndirectReferenceTable, the error message was lost. Now expose and include the error message when throwing an exception related to failures to construct the IndirectReferenceTable. The error message is propagated through JVMEnvExt, JavaVMExt, and Runtime::Init as well. Bug: 32013594 Test: Added new 151-OpenFileLimit runtest.

2016-10-18Remove mirror:: and ArtMethod deps in utils.{h,cc} David Sehr
The latest chapter in the ongoing saga of attempting to dump a DEX file without having to start a whole runtime instance. This episode finds us removing references to ArtMethod/ArtField/mirror. One aspect of this change that I would like to call out specfically is that the utils versions of the "Pretty*" functions all were written to accept nullptr as an argument. I have split these functions up as follows: 1) an instance method, such as PrettyClass that obviously requires this != nullptr. 2) a static method, that behaves the same way as the util method, but calls the instance method if p != nullptr. This requires using a full class qualifier for the static methods, which isn't exactly beautiful. I have tried to remove as many cases as possible where it was clear p != nullptr.

This allows one to pass shared-libraries on the command line that the runtime will load as plugins. They have access to runtime code and can install hooks to add functionality.
