625874 - Running Talos ts throws "Unable to remove directory" at the end of the run

Status: RESOLVED FIXED

(Testing :: Talos, defect)

Description

[cmtalbert]

Attachment: the config file

1. Get a tegra set up with the agent, watcher, fenneccp, firefoxcp, and fennec.
2. run talos with the attached config file: python run_tests.py --noisy mine.yml
3. Wait, make coffee
4. Wait some more, eat a sandwhich

At the end of the ts run, you will see that there is a notice from ffprocess_remote stating "Unable to remove directory", and it's calling to the agent trying to remove a directory and failing to do so.

The directory it is trying to remove is the temp directory it used to store the profile in on the *local* computer.  It's something like "/tmp/tmp<randomchars> which does not, cannot, and will not exist on the device.  So, either something in ffprocess_remote (or more likely) something in our super class ffprocess is trying to remove the temp directory it used to store the profile before sending it to the device, but our remote code thinks that this is a directory on the device when it isn't and hence you get the error.

This needs to be cleaned up in ffprocess_remote/ffprocess (probably somewhere in that interaction between the two classes).

Note, I'm running with the talos-devicemanager patch on bug 624001 when repro'ing this.

Attachment: allow talos to differentiate between host and remote ffprocess (1.0)

this patch will add in a self.hostproc variable such that when we need to do actions on the host or remote device we can choose the correct version.  By default it sets hostproc = _ffprocess.
