| * | Refuse to write optimized dex files to a non-private directory.Jesse Wilson2012-01-061-0/+16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's infeasible to test if other applications can write to a given directory, particularly since directories like /sdcard/ are accessible to named groups like sdcard_rw. Instead we take a shortcut and just test that the optimized directory is owned by the current process. I tested this manually; the '/data/data/vogar.test.java.StatTest/' app directory could be successfully used but other directories ('/data', '/sdcard', '/') throw exceptions as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will let the BlockGuard attempt to set tags. For now, it will silently do nothing if the needed /proc/net/xt_qtaguid/ctrl file is not available. It distinguishes "t"agging from "u"ntagging. For now, it does not pass down the tag as a string, but just its hash. It doesn't attempt to control the module when nothing needs doing. This needs the kernel with the new xt_qtaguid netfilter module. And the new system/netd bandwidth management support that sets up the iptables. Change-Id: Ie20def02f8d6aa4b67249f1b46ec5aefb9396305

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of PlainSocketImpl.accept is made ugly by the fact that the SocketImpl we mutate may share its FileDescriptor with a SocketChannel, so we need to mutate the FileDescriptor itself, and can't simply swap in a new one. I've raised http://b/4452981 to see if we can integrate the nio and io socket classes more closely, to avoid this kind of mess. Bug: 3107501 Change-Id: I4964b64c25e936a44d1e4c22504ca29bba247ab6

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I wasn't planning on touching this code (since I want to replace it), but the purported "fix" for http://code.google.com/p/android/issues/detail?id=6309 was actually a regression. The supplied test fails on the RI. This patch replaces the bogus test with new tests, and reverts the old "fix". This was found while trying to work out what "true" and "false" return values from OSNetworkSystem.select are supposed to mean. This patch also switches to a more traditional int return value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new NET_FAILURE_RETRY in Posix.cpp is intended to replace the legacy one in NetFd.h, but during the transition we need both. The new one also takes care of the asynchronous Socket.close semantics, and changes the behavior when the FileDescriptor is invalid on entry: that is now reported as EBADF; it's only reported as "Socket closed" when we've been round the loop at least once, giving us reason to believe the socket was ever open. Having had to debug this distinction, I think the new semantics are less confusing. Bug: 3107501 Change-Id: I243dc4fa2eddde7ba40e9b66ec8fc555bc4e80f9
* | | Expose bind(2).Elliott Hughes2011-05-091-6/+0
|/ / | | | | | | | | | | | | | | | | | | I've renamed the java.net.InetAddress to struct sockaddr conversion functions too, after initially screwing up this patch by copy & pasting a usage of the one that only one caller actually wants. Now the name's so ugly no-one will be likely to use it by accident. Bug: 3107501 Change-Id: I869a8d27fc40e462505e02bf25a67e771a403e92
* | 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.

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.

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
