IPC plumbing for TraceWriter and service-side Consumer port. This CL fixes most of the IPC plumbing after TraceWriter and related methods are landed. This mainly reduces the need of keeping .proto and core objects in sync. Also exposes the service-side implementation of the Consumer port. Finally gets rid of the ObserverForTesting, which at the end turned out to be unneeded. Bug: 70284518 Bug: 68854243 Change-Id: I5e9156fee2945dc8bd42d7016046afb7da643411
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
Android is the platform targeted in the first milestones. Right now Linux desktop and OSX are maintained best-effort.
All dependent libraries are self-hosted and pulled by the tools/install-build-deps
script.
The only requirements on the host are python, git and a compiler (preferably clang, gcc is maintained best-effort):$ sudo apt-get update && sudo apt-get install git clang python
Then:$ git clone https://android.googlesource.com/platform/external/perfetto.git
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.
If you are a chromium developer and have depot_tools installed you can avoid the tools/
prefix below and just use gn/ninja from depot_tools.
$ tools/install-build-deps
to install third-party build deps (NDK etc)
$ tools/gn args out/android
to generate build files and enter in the editor:
target_os = "android" # Leave empty for local testing target_cpu = "arm" or "arm64" # Only when building for Android
(See the Build Configurations section below for more)
$ tools/ninja -C out/android all
TODO. The plan is to autogenerate the Android.bp build files from the master GN build files (or temporarily maintain both until we can autogenerate them).
$ tools/ninja -C out/default (tracing_unittests | tracing_benchmarks) $ out/default/tracing_unittests --gtest_help
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
The following GN args are supported:
target_os = "android" | "linux" | "mac"
:
Defaults to the current host, set "android" to build for Android.
target_cpu = "arm" | "arm64" | "x86" | "x64"
:
Defaults to "arm"
when target_os
== "android"
, "x64"
when targeting the host. 32-bit host builds are not supported.
is_debug = true | false
:
Toggles Debug (default) / Release mode.
is_clang = true | false
:
Use Clang (default) / GCC. It requires clang 3.5+ to be installed on the host. Clang is the default compiler on Mac (% having installed Xcode). On Linux: sudo apt-get update && sudo apt-get install clang
cc = "gcc" / cxx = "g++"
:
Uses a different compiler binary (default: autodetected depending on is_clang).
is_asan = true
:
Enables Address Sanitizer
is_lsan = true
:
Enables Leak Sanitizer
(Linux/Mac only)
is_msan = true
:
Enables Memory Sanitizer
(Linux only)
is_tsan = true
:
Enables Thread Sanitizer
(Linux/Mac only)
is_ubsan = true
:
Enables Undefined Behavior Sanitizer
