Fix streaming replies and expose peer info This CL introduces some smaller fixes to the IPC layer, specifically: - Fixes the support for streaming replies and adds a test for it. - Exposes the peer_uid() of the endpoint both at the Socket and IPC level. This will be used by the tracing service to recognize requests coming from the same client and enforce per-uid limits. Bug: 68854111 Change-Id: Ib5b4b8e9ec792556df262feba67bd54fbf29d64f
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 build/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 build/ prefix below and just use gn/ninja from depot_tools.
$ build/install-build-deps to install third-party build deps (NDK etc)
$ build/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)
$ build/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).
$ build/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:$ build/run_android_emulator (arm | arm64) &
To run the tests (either on the emulator or physical device):$ build/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
