akash provider lease-shell and the way it handles EOF

[arno01]

akash v0.16.4-rc2.

There are different use-cases getting broken due to the way akash provider lease-shell handles EOF.

1. Can upload the data into the container using this command, despite the error:

$ tar -cf - -C /usr/share -- info | akash provider lease-shell --stdin app1 -- tar -xf - -C /root
Error: EOF: failed while reading from stdin

2. When passing "z" flag (compressed tar), it just hangs until I Ctrl+C it:

$ tar -czf - -C /usr/share -- info | akash provider lease-shell --stdin app1 -- tar -xzf - -C /root
halted by signal: interrupt

even a small file:

$ tar -czf - -C /etc -- hosts | akash provider lease-shell --stdin app1 -- tar -xzf - -C /root
halted by signal: interrupt

3. It is waiting forever on user input (neither Ctrl+D is helping):

$ echo hi30 | akash provider lease-shell --stdin app1 -- cat -
hi30
<prompt hangs in here>

I think the correct behavior here would be

1. --stdin close when EOF is received by the local process
2. --tty - expect interactive console with user input

Todo

• [x] check provider-services 0.1.0 (and 0.1.1-rc1 probably as well)

Have tested provider & client both running provider-services 0.1.1-rc1, results are the same.

the issue still persists:
