* Add Socket tagging for granular data accounting.Jeff Sharkey2011-05-131-4/+92
| | | | | | | | Changes BlockGuard to maintain a set of "tags" for the current thread, which it communicates to kernel before each Socket use. Also changes HttpConnectionPool to tag/untag sockets as they are recycled. Change-Id: I33e614f1f570466bdffbf07cc5c718f18b8f3773
* Fix non-blocking connects.Elliott Hughes2011-05-031-3/+1
| | | | | | | | | | The key change here is reintroducing the boolean return value, which we need as long as the native code treats EINPROGRESS as a special case which doesn't throw. The rest is just drive-by incremental cleanup of the code. Change-Id: I761b052adbb14e912c3853a35327f8a589cd4023
* Rewrite blocking connects in terms of the non-blocking primitives.Elliott Hughes2011-05-021-9/+2
| | | | | | | | | | | | | | | | | | | | | This simplifies OSNetworkSystem, getting us closer to replacing the connect(2)-related bits with our new POSIX interface. It also lets us remove cruft on the Java side that was resetting the socket's blocking/non-blocking state (which should never have been touched), which in turn fixes bug 4193212. Detail messages for socket timeouts get better too, now we're throwing on the Java side. The only thing that's worse is that we used to get away with throwing a checked exception from native code, which simplified our "throws" clauses. Now we actually have to jump through a few hoops to make javac happy. (Especially awkward because SocketTimeoutException isn't a SocketException.) Stupid checked exceptions.

* Implement reference queuing in managed code.Carl Shapiro2011-03-301-0/+3
| | | | | | | | | | | | | This change adds a thread to the core library which receives a list of references after a garbage collection and enqueues each element. This list is constructed by linking together the pendingNext field of cleared references into a circular queue. To support this change, the pendingNext field has been replaced by the new zombie field for the purposes of providing a strongly reachable location within a FinalizerReference class instance.

| * SamplingProfilerIntegration and SamplingProfiler improvements (2/3)Brian Carlstrom2011-03-2911-80/+390
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: frameworks/base - fix profiling to collect data beyond the first snapshot - avoid many small files, accumulate data over process lifetime libcore: - add support for VM specific sampling, trying to cut down overhead - added support for converting snapshot files to text format - fixed race in profiler when stopping dalvik - added VMStack.setThreadStackTrace interface for filling a stack trace into an existing StackTraceElement[] Details: frameworks/base Changed snapshots from text to binary hprof format (bumping version to 3) Changed from one file per snapshot to one file per process lifetime. Restart profiling after snapshot. core/java/com/android/internal/os/SamplingProfilerIntegration.java Add quick test in maybeSnapshot to avoid doing work when the SamplingProfilerIntegration is disabled. Make maybeSnapshot private. Remove unneeded memory allocation in handleLowMemory. core/java/android/app/ActivityThread.java libcore Added ThreadSampler interface. This allows VM specific thread sampling optimizations. The portable version continues to use Thread.getStackTrace(). dalvik/src/main/java/dalvik/system/profiler/ThreadSampler.java dalvik/src/main/java/dalvik/system/profiler/PortableThreadSampler.java dalvik/src/main/java/dalvik/system/profiler/SamplingProfiler.java Add VMStack.setThreadStackTrace and use in new DalvikThreadSampler to avoid allocating a full stack trace when only a limited depth is desired. dalvik/src/main/java/dalvik/system/profiler/DalvikThreadSampler.java dalvik/src/main/java/dalvik/system/VMStack.java Refactored BinaryHprof.readMagic out of BinaryHprofReader so it can be used by HprofBinaryToAscii converter to probing file types. Added magic number constant to be shared between readMagic and BinaryHprofWriter. dalvik/src/main/java/dalvik/system/profiler/BinaryHprof.java dalvik/src/main/java/dalvik/system/profiler/BinaryHprofReader.java dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java Removed unneeded HprofWriter interface. Changed to simpler static interface to write HprofData to binary and text formats. dalvik/src/main/java/dalvik/system/profiler/HprofWriter.java dalvik/src/main/java/dalvik/system/profiler/AsciiHprofWriter.java dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java dalvik/src/test/java/dalvik/system/profiler/SamplingProfilerTest.java Added support for reading snapshot files created by SamplingProfilerIntegration by stripping the text header to allow easier conversion to the text format. dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java Fixed race between Sampler and SamplingProfiler.stop. SamplingProfiler.stop previously simply called the Sampler's TimerTask.cancel method, but this does not wait for a currently running Sampler to finish. The TimerTask documentation says the only reliable way to do this is to have the run() cancel itself, so that is what is now done, with new code to ensure that SamplingProfiler.stop does not return until the Sampler has been terminated. dalvik/src/main/java/dalvik/system/profiler/SamplingProfiler.java dalvik Refactored VMStack_getThreadStackTrace to create helper getTraceBuf used to implement new VMStack_setThreadStackTrace. The new version interface fills an existing StackTraceElement[], avoid allocating unnecessary StackTraceElements. vm/native/dalvik_system_VMStack.c Refactor dvmGetStackTraceRaw to create dvmSetStackTraceRaw which fills in an existing, potentially smaller, StackTraceElement[]. vm/Exception.c vm/Exception.h Change stack depths to be unsigned to avoid signed/unsigned comparison warnings. vm/Ddm.c vm/Exception.c vm/Exception.h Change-Id: Id65df6e72b7c727a0c8af15dbf6943297c591541
* | Add socket(2) and start adding setsockopt(2).Elliott Hughes2011-03-291-4/+0
| | | | | | | | | | | | | | | | I've added just enough setsockopt to keep the hack from our old socket creation code. More later (but not necessarily right away). Bug: 3107501 Change-Id: Id57bdd3c760bc58ed79d675b268c55493cbc24c8
* | Add sendfile(2).Elliott Hughes2011-03-291-18/+0
| | | | | | | | | | | | | | | | | | | | | | This patch marks the end of OSFileSystem. Having to support a Java "long*" for sendfile(2) gave me an opportunity to go back and improve my ioctl(2) to use a corresponding "int*" equivalent, instead of its previous special-case hack. Bug: 3107501 Change-Id: I9fde4777700552263fab4fe9aeb556174163e3dc
* | Add readv(2)/writev(2).Elliott Hughes2011-03-291-12/+0
| | | | | | | | | | | | | | | | | | | | The old implementation would cheat if it was given non-direct buffers, copying them into newly-allocated direct buffers. (The network Channel implementations are worse: they copy all the data into a single buffer, and then read/write that. I'll get to them eventually.) Bug: 3107501 Change-Id: I1655bacb042e7ebcde7e5bc5cf2c71e7ce5e30af
* | Add ioctl(2) for int*.Elliott Hughes2011-03-281-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | I'm not adding the "struct ifreq" stuff yet because that's really hairy and I plan on rewriting the NetworkInterface implementation anyway, so it'll mainly be based on /proc. With any luck, we won't even need those other ioctls then. I'm not sure _this_ ioctl is a good idea, but it does seem like a slight improvement on the old code, and we can always move it back out if/when these APIs become more public.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note that this is a functional change, because the old code was wrong: it assumed that short writes don't happen. I thought we'd (I'd) cleaned this up just recently, but it looks like I must have only gone through the network code. Embarrassing. This also cleans up the previous read change a bit, factoring out a bit more duplication, and taking advantage of the fact that we now get decent exceptions thrown from invalid FileDescriptors (meaning we can remove explicit checks).

* | Add fcntl(2).Elliott Hughes2011-03-241-9/+0
| | | | | | | | | | | | | | | | | | | | I initially used overloading, but that actually decreases safety in practice because which overload you need is (uniquely) determined by the specific command you're issuing. Forcing callers to explicitly state what they're doing works around this. As it was, I had to use strace(1) to find my bug. Bug: 3107501 Change-Id: Ia54b72dd6453372922f01b22f382eb93ac91aaa7

| | | | | | | | | | | | | | | | | | The claim that "the port library" modifies the file offset appears to only ever have been true of Harmony's Win32 implementation.

The special case in FileDescriptor.sync has been removed. Testing with the RI showed that it doesn't treat syncing a FileDescriptor that corresponds to a socket as a special case --- it throws SyncFailedException just like normal.

If the return value is not checked, the caller will not be able to correctly handle the case where fewer bytes were read than the caller requested. This is a particularly insidious kind of bug, because in many programs, reads from input streams usually do read the full amount of data requested, causing the program to fail only sporadically."

The former is only called with one input value that doesn't exercise the bug, and the latter would cause us to think that a time zone that stopped using daylight time before 1970 was still using daylight time (which would defeat various optimizations, but should otherwise be harmless).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This resulted in the creation of two new classes: DexPathList contains most of the common functionality, namely managing the two path lists (dex/resource files and native library directories) plus all the salient initialization and lookup code. BaseDexClassLoader provides the ClassLoader API, mostly by making calls to a contained DexPathList instance. The two original classes just become trivial subclasses which take different constructor args and make correspondingly different super() calls in their respective constructors. I took the opportunity to remove the ability for PathClassLoader to take directories on the dex/resource list. This functionality hadn't ever been used, at least not since well before 1.0.
