SamplingProfilerIntegration and SamplingProfiler improvements (3/3)
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

Resurrect SamplingProfilerIntegration
1.) Change from samples per second (persist.sys.profiler_hz) to
interval between samples (persist.sys.profiler_ms) to match
underlying SamplingProfiler API. This allows samples to be taken
less often than a second, which allows lower overhead for always
on profiling.
2.) Add persist.sys.profiler_depth to control the number of frames
kept. Currently defaults to 4 which is the default hprof depth,
but often 12 is necessary even in benchmarks to get a good idea
where time is being spent.
3.) Moved SNAPSHOT_DIR creation to initialization time instead of
checking it on every sample.
4.) Used ThreadFactory to provide human readable name to writeSnapshot
Executor thread.
5.) Fixed bug where writeZygoteSnapshot was calling wrong variant of
writeSnapshot causing profiling to prevent zygote startup. Renamed
underling private writeSnapshot to writeSnapshotFile to try to
prevent future confusion.

New Java-based SamplingProfiler
Summary:
- libcore: new Java based SamplingProfiler
- dalvik: remove old SamplingProfiler native bits
- frameworks/base: New placeholder SamplingProfilerIntegration
- vendor/google: remove old profiler snapshot parsing code
Details:
libcore
A new 100% Java SamplingProfiler. While it has more overhead that
the old native one, the new one can actually collect more than the
current PC and frame pointer, so you can get useful context of
where your app is spending time. It currently provides ASCII hprof
format output for use with tools like PerfAnal
dalvik/src/main/java/dalvik/system/SamplingProfiler.java
Unit test for the new SamplingProfiler
dalvik/src/test/java/dalvik/system/SamplingProfilerTest.java
Add core-tests-dalvik
JavaLibrary.mk
dalvik
Removing native code that supported the old SamplingProfiler
vm/Dvm.mk
vm/native/InternalNative.c
vm/native/dalvik_system_SamplingProfiler.c
frameworks/base
Placeholder SamplingProfilerIntegration. Later plans include
generating EventStackTrace protobufs.
New SamplingProfiler does not have a global instance, so
SamplingProfilerIntegration provides one in INSTANCE. Old binary
snapshot format is temporily replaced with ASCII hprof data.
core/java/com/android/internal/os/SamplingProfilerIntegration.java
Simplified interface for zygote profile snapshotting
core/java/com/android/internal/os/ZygoteInit.java
Current SamplingProfilerIntegration does not track event loop
explicitly, but hprof information does include thread information.

wire up sampling profiler to dropbox
When system property "persist.sys.profiler_hz" > 0, SamplingProfilerService is
loaded to SystemServer. It creates a FileObserver, watching any new file in the snapshot
directory. When a snapshot is found, it is put in dropbox and deleted after that.
SamplingProfilerIntegration writes snapshots with headers. Headers are <name, value> pairs,
instantiated by caller.
Currently header format is (also in source comment):
Version: <version number of profiler>\n
Process: <process name>\n
Package: <package name, if exists>\n
Package-Version: <version number of the package, if exists>\n
Build: <fingerprint>\n
\n
<the actual snapshot content begins here...>
