cosmos72 / detachtty Goto Github PK

Reported by Matthias Urlichs in 2002, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=168380

detachtty doesn't work with command-line editing programs.

To reproduce:

• detachtty /tmp/s1 /bin/bash
• attachtty /tmp/s1
• press arrow-up; you get ^[[ instead of the previous history item.

The problem is that attachtty needs to set its own stdio to 100% raw
mode (and clean up after itself when it exits).

hi,

i found myself wanting to use a script to send some lisp code to a
dettachtty'd lisp server. unfortunetly the first thing i could think
of 'echo (foo) | attachtty /socket' doesn't work since the stdin
socket gets closed. i don't think attachtty should deal with that
since when attachtty is used interactily that should be an error
(though doing something other than looping forever spitting out
error messages migth be nice). so, i figured adding an --eval
argument was the smartest thing to do.

the attach attachtty.c accepts a '--eval CODE' argument. when passed
CODE is sent directly to the socket and the connection is closed,
when the --eval argument isn't passed it runs like before.

i don't think my coding style is the best so if you want feel free
to edit/refactor/maul as much as you like.

Currently, detachtty unconditionally sets the umask to 077 before
opening the socket. This bothers me somewhat because I would like to
make the socket accessible to a group rather than just a single user.
(Even an option telling the program that I know it thinks it's a bad
idea but I'd really like to would be nice.)

Removing the umask fixing can be accomplished easily by removing lines
80, 128, and 160 of detachtty.c

Thank you very much.

The description of --pid-file in the manpage for detachtty/attachtty
states "The process ID of attachtty is written to pidname." when it
should read "The process ID of detachtty is written to pidname."
