A valid concern, it did cross my mind as well. However, I have yet to
think of a better way to achieve all the features that are wished
for. Any suggestions?
Anyway, I have implemented some of the changes already. The patch is
again attached to the issue. Everything is still subject to change,
however. But, this is how setting up a process would look like at the
def processSetup(self, proc):
proc.addHelper(PTY('pty', [0, 1]))
This would configure the process to have uid 1000 and gid 1000, the
executable to be started in path /tmp, file descriptors 0 and 1 would
map to a PTY on the child, which would come in as
childDataReceived('pty', data) on the process protocol, file
descriptor 2 would be the parent's stderr and file descriptor 3 would
be a write pipe by the name of passphrase, that would be written as
This is still lacking the ability to give different protocols to
different communication channels and the chdir/chroot/whatever helper
logic is hackish.
So, feedback is very much appreciated, as always. Regardless, I'll
holler on the list again when I think of where to go next with this
