new core enhancement https://tm.tl/#8890 by hawkowl: async/await doesn't work with chained Deferreds

Amber Brown <hawkowl@atleastfornow.net>; closed <https://tm.tl/#8878>; - Already-failed Deferred doesn't re-raise exception when awaited

I'm trying to start a process, with line-oriented stdin/stdout, but I get an exception

builtins.AttributeError: '_ProcessEndpointTransport' object has no attribute 'disconnecting'

o11c, it could be trying to disconnect before it's connected?

dpn`: I don't *think* so, since before I fixed the delimiter, I could see the process existed

actually, the process *exists* even despite this error

I think this is a bug: twisted is schizophrenic about whether transports are required to have the 'disconnecting' attribute or not

I assume only TCP endpoints do

o11c, can you show which line that error is happening on?

after run(), it's not in my code

i mean which line in which twisted file.. you're not getting a stacktrace?

(and #L573 for the LineReceiver class instead of LineOnlyReceiver)

o11c, have you defined your own Protocol? Can you show that?

assuming you're on linux

That gist is my entire code

sorry i missed the gist

process, not stdio

gdb spits out a bunch of info on startup, so the dataReceived callback is called without any further code on my part

yeah but the parent child fd's are handled with stdio

the pipes to the child process

do you have the full stacktrace?

refresh the gist

I'm 95% sure that your stdio link is totally unrelated, the child isn't using twisted ...

ah sorry my bad

have my head in ampoule land too much

hmm I'd have to dig into it more sorry

I'm still a bit behind when using endpoints

but even so, you could try p = GdbMiProtocol();p.transport.disconnecting = False or something to hack around it

but it does seem like something is being called/happening before the transport is fully initialised

in connectionMade?

yeah, that works

_ProcessEndpointTransport inherits from something dynamic so it's hard to tell what's going on

sorry, meatspace calls

What changed in twisted-16.5.0 with respect to the setup.py install????

I am getting a sandbox violation on a Gentoo system

File "/usr/lib64/python2.7/site-packages/setuptools/command/easy_install.py", line 1102, in run_setup

raise DistutilsError("Setup script exited with %s" % (v.args[0],))

distutils.errors.DistutilsError: Setup script exited with error: SandboxViolation: mkdir('/var/tmp/portage/dev-python/twisted-16.5.0/work/Twisted-16.5.0-python2_7/incremental.egg-info', 511) {}

this is a new problem
