Notes on setting up a local instance of the Catapult dashboard for development purposes. These instructions were only checked to work on a Linux workstation and might or might not work on a Mac host.
Get a copy of Catapult from https://github.com/catapult-project/catapult .
Download Google Cloud SDK and put it in PATH as demanded in Catapult prerequisites. Then hack it up - edit platform/google_appengine/google/appengine/tools/devappserver2/dispatcher.py and in _resolve_target(), replace:
try: _module, inst = self._port_registry.get(port) except KeyError: raise request_info.ModuleDoesNotExistError(hostname)
with
try: _module, inst = self._port_registry.get(port) except KeyError: _module, inst = None, None
This is a workaround for https://code.google.com/p/googleappengine/issues/detail?id=10114 and allows dashboard's task queue to work when the host name is other than localhost.
cd dashboard && bin/dev_server --host=0.0.0.0
By running the dev server on 0.0.0.0 we ensure it is reachable from all network interfaces.
Run Fuchsia. Take note of the ip address of your Fuchsia qemu interface by running ifconfig on the host.
Run wget http://<ip address>:8080 to ensure that the dashboard is accessible from Fuchsia. If this works, you're all set - run trace record with the result upload parameters, including --upload-server-url=<ip address>.
On the host, visit http://localhost:8080/update_test_suites and http://localhost:8080/update_test_suites?internal_only=true to make newly added test suites appear in the test suite picker.
