docker attach hangs on exit when container is run with -i -d #1869

This prints Hello and World to the console:

sudo docker run ubuntu /bin/bash -c 'sleep 1; echo Hello'; echo World

This hangs after the container exits, only printing Hello:

cid=$(sudo docker run -i -d ubuntu /bin/bash -c 'sleep 1; echo Hello'); sudo docker attach $cid; echo World

Any additional key presses cause it to exit and print World, but this is troublesome for scripts.

Could this be related to #1300? What operating system is the host? Can you show the output of running the docker daemon with debug output turned on?

I think this is fixed on master, can you confirm ?

No, it is not fixed. It is a different issue than hang after escape sequence.

I think I may be experiencing this issue with docker version 1.2 when trying to do:

 sudo docker attach e728d7b26857

uname -a for host:

    Linux android-host-2 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Container based on official Ubuntu 12.04.

Command used to run container:

sudo docker run -u=root -v /home/full_tests:/home/full_tests  -e PATH=$PATH:/android-sdk-linux/platform-tools -i -d --privileged --device /dev/bus/usb/001/001 10d7ec2cfa4d /home/myuser/myscript.sh

Ctrl+C doesn't do anything, and attach command just sits there:

myuser@android-host-2:~$ sudo docker attach e728d7b26857

^C

I am happy to be told that I am doing something wrong. The documents for attach don't mention anything about which kind of startup processes you can/cannot attach to. However in the examples I have seen it's /bin/bash or like in the docs it's /usr/bin/top

http://docs.docker.com/reference/commandline/cli/#attach

(I realise this is issue is closed, does that mean nobody will look at it?)
I am happy to provide more information and help debug if necessary..
