Pass read-only file to dropbox uploader
It seems that the dropbox API internally switches to the
system_server label while uploading (likely it starts a new thread).
system_server has read-only SELinux permissions on
/data/misc/perfetto-traces. This CL passes a read-only copy of the
file descriptor to Dropbox to work around this.
The violation looks like this:

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.
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.
See docs/build_instructions.md
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.
