probe_producer: Post metadata to helper sources

ftrace_reader needs a way to signal to the inode/ps metadata sources
with vectors of intresting inodes/pids. It should signal only data
sources which belong to the same tracing session. These sources may not
exist. Rather than keeping many parallel maps up to date and having
lookups in the fast path instead everytime a new datasource is created
we do a pass though all the ftrace datasources and try to set weak
pointers on them leading to the corresponding inode/ps datasources.
Then when we see metadata we post task to relevent datasource via the
weak pointer.

Perfetto - Performance instrumentation and logging for POSIX platforms

This project is meant to be built both as part of the Android tree and from a standalone checkout

For internal docs see this page

Supported platforms

Android is the platform targeted in the first milestones. Right now Linux desktop and OSX are maintained best-effort.

Contributing

This project uses Android AOSP Gerrit for code reviews and uses the Google C++ style. Currently targets -std=c++11.

You can use both git cl upload from Chromium depot tools or Android repo to upload patches.

git cl is quite convenient as it supports code auto-formatting via git cl format.

See https://source.android.com/source/contributing for more details about external contributions and CLA signing.

Build instructions

See docs/build_instructions.md

Running Perfetto

See docs/running_perfetto.md

Continuous integration

Continuous build and test coverage is available at perfetto-ci.appspot.com. Trybots: CLs uploaded to gerrit are automatically submitted to TravisCI within one minute and made available on the CI page above. The relevant code lives in the infra/ directory.

Run tests

On the host (Linux / OSX)

$ tools/ninja -C out/default (tracing_unittests | tracing_benchmarks)
$ out/default/tracing_unittests --gtest_help

On Android

Either connect a device in ADB mode or use the bundled emulator.

To start the emulator:
$ tools/run_android_emulator (arm | arm64) &

To run the tests (either on the emulator or physical device):
$ tools/run_android_test out/default tracing_unittests
