subshell is not working with dash

Description

if root uses dash as a default login shell than mc is unable to engage subshell (ctrl+o) with error message about not xterm or linux console.

Note: I can run dash as regular user and mc works just fine in it, but "sudo mc" gives the error described above. If root's default login shell is switched to bash than 'sudo mc' works as expected.

Note to self: patch to fix this probably available in #2742

comment:3 Changed 10 years ago by god12

  • Version changed from 4.8.8 to 4.8.13

mc 4.8.13

There's no error message anymore but shell prompt is not displayed after ctrl+o and if I press any key mc panels are back as if I've pressed ctrl+o again.

So it's still completely broken.

I can confirm this root-dash-mc-subshell bug in 4.8.15
which is resolved in current git version.

@andrew_b, so shall we close this as a duplicate of #2742?

@andrew_b, also, regarding milestones, see my suggestion in #2707.

Replying to zaytsev:

I don't know. I don't use dash.

Ok, I've checked it with 4.8.15 and current master (4.8.15-218-g4d5c1b2). With 4.8.15 it doesn't work at all, that is, subshell support is completely deactivated. With current master it works to a degree (subshell support is initialized, running commands in prompt works, CTRL+O works).

However, there is still an annoying a bug. When one switches from panels to console with CTRL+O, ^H (literally) is printed to the prompt. Many switches back and forth result in more ^H. They can be simply deleted by hand, but otherwise cause errors when running commands. Tested on dash 0.5.5.1, can't try a newer one for now.

@and, you're saying it works for you, can you reproduce the ^H issue, if not, which version of dash have you used for testing?

I have simple tested, no in deep testing because I not a dash lover.
In 4.8.15 no subshell was here, in current master subshell was testing by simple commands.
