2017-08-14simpleperf: export more info through report_lib_interface.Yabin Cui
Make below changes to better suppport inferno: 1. Save product properties of device in perf.data. 2. Add a python/c api GetFeatureSection. It is used to support reading record cmd and meta info from perf.data. 3. Remove old api GetNextMetaInfo, because meta info can be exported by GetFeatureSection more easily. 4. When reading perf.data in record_file_reader.cpp, remove callchain at and below ip == 0 to avoid caller's effort. Also move to use android-base/properties.h. Bug: http://b/64035530 Test: run simpleperf_unit_test and test.py. Change-Id: Ib6743a09167e2b7cd65a12f17d991bc1ac628588

2017-08-11simpleperf: improve warning msg.Yabin Cui
The warning of missing symbol for each lib is shown twice, once in recording, and once in reporting. This is redundant and maybe misleading. Because when reporting we actually don't know if we have collected enough symbols in perf.data. So move warning of missing symbols to debug info if we have symbols in perf.data. Use customized StderrLogger, because simpleperf doesn't need time,pid,tid information in log. Bug: http://b/29574526 Test: run simpleperf manually and run simpleperf_unit_test.

2017-08-07simpleperf: allow recording events in different speed.Yabin Cui
Currently record command interface only allows one sample freq or sample period for all events. This is not convenient when recording both non tracepoint events and tracepoint events. This CL allows setting different sample speed for different events. For example, for "-f 1000 -e cpu-cycles -c 1 sched:sched_switch", "-f 1000" applies to cpu-cycles, and "-c 1" applies to sched:sched_switch. It also fixes a bug about trace-offcpu: if "-f 1000 --trace-offcpu" is used, the sched:sched_switch is be samples with "-f 1000". But we want to sample it with "-c 1". Also change the order of options in the help msg of record cmd to make it more readable. Remove -F option. Because adding it seems not useful. Bug: http://b/37572306 Test: run simpleperf_unit_test.

To support perf.data generated with --trace-offcpu option, update interface in report_sample.proto: 1. Add meta info to show all event types. 2. Add event_type_id in each sample to show which even type it belongs to. Bug: http://b/37572306 Test: run simpleperf_unit_test. Change-Id: I2878979ec2023904df1006ce353dcf233b6a2642

2017-08-03simpleperf: support profiling native programs in app_profiler.py.Yabin Cui
This is a preparation of using app_profiler.py in inferno. In app_profiler.py: Add -np option to profile native programs like surfaceflinger. Add -cmd option to profile command lines. Add --arch option to set the app arch, because we don't guess the app arch when profiling command lines. Add corresponding tests in test.py. Also improve the way of detecting whether the device supports trace-offcpu. Bug: http://b/63006886 Test: run test.py. Change-Id: Id899063d9a94beec67b22fd7710cda7a438557fb

2017-07-25Fix a memory leakGeorge Burgess IV
This fixes the following memory leak: system/extras/tests/tcp_nuke_addr/tcp_nuke_addr_test.cpp:146:20: warning: Potential memory leak [clang-analyzer-cplusplus.NewDeleteLeaks] Namely, clang was upset that we didn't free the std::threads we new'ed up. Immediately detach()ing them gets us the same effect. (Context: We're trying to clean up scary-sounding warnings like this in Android. I realize that, in this case, a leak is harmless, but...) Bug: 27101951 Test: mma. Memory leak warning is gone. Ran the test on bullhead for 60s; seemed to work (last line of output is "60s: 246 cps, total 25432") Change-Id: I4b6b5679430968e01ffea5bc10309a4ced04ba4e
