In that mc shell, try this: echo $PROMPT_COMMAND $ echo $PROMPT_COMMAND pwd>&7;kill -STOP $$ Okay, that PROMPT_COMMAND setting is the whole problem. I can't imagine the purpose that it serves, and it makes no sense within the context of how portage uses it. As a workaround, you can do this:
export -n PROMPT_COMMAND
Or set this in make.conf:
FEATURES="${FEATURES} notitles"
unless you can show a valid use case for that PROMPT_COMMAND, i'd suggest following Zac's suggestion. there's not an easy way for us to detect this case and then ignore PROMPT_COMMAND. portage is doing what you told it to do. |
When running emerge in mc's (midnight commander's) subshel, and mc is running in gnu screen session, then every emerge output ends with `bash: 7: Bad file descriptor' and shell do not show prompt. If type Ctrl+C now it shows ^C ==================================== Error in portage.process.run_exitfuncs File "/usr/lib64/portage/pym/portage/process.py", line 134, in run_exitfuncs func(*targs, **kargs) File "/usr/lib64/portage/pym/_emerge/actions.py", line 3836, in emergeexit xtermTitleReset() File "/usr/lib64/portage/pym/portage/output.py", line 289, in xtermTitleReset 2:sys.stderr.fileno()}) File "/usr/lib64/portage/pym/portage/process.py", line 323, in spawn retval = os.waitpid(pid, 0)[1] File "/usr/lib64/portage/pym/portage/__init__.py", line 246, in __call__ rval = self._func(*wrapped_args, **wrapped_kwargs) ==================================== and no shell prompt again.

Bug can be reproduced only in combination "mc inside of screen" but not "screen inside of mc"
