[screen-devel] [bug #49883] Run mc inside screen + resize terminal + ctrl-a esc + pgup pgup pgup = bug

[Askar Safin]

Follow-up Comment #7, bug #49883 (project screen):

I tested again.
"altscreen on" really (something like) ignored now.

Steps I used.

My host system is debian stretch. I run this command (to create chroot
environment with another debian stretch in it):

$ sudo debootstrap --variant=minbase stretch /tmp/s
http://ftp.debian.org/debian

Then, in newly created system:

# apt-get install mc
# apt-get install gcc make git
# git clone https://git.savannah.gnu.org/git/screen.git # commit
a48e1f96dc329cd0fc28ed91890dd19f4d12a47c
# cd screen
# cd src
# apt-get install automake autoconf
# ./autogen.sh
# apt-get install libc6-dev
# apt-get install libncurses5-dev
# ./configure --prefix=/opt/screen-2017-04-11
# make
# make install
# apt-get install systemd-sysv systemd
# passwd -d root

Then, at host we boot this chroot environment using systemd-nspawn:

$ sudo systemd-nspawn -bD /tmp/s

Then, in newly booted container:

# mcedit ~/.screenrc
# cat ~/.screenrc
altscreen on
startup_message off
# /opt/screen-2017-04-11/bin/screen

Then I see "startup_message off" took effect (so, screen uses this config),
but "altscreen on" is ignored.

If you want, I can send you this chroot environment.

---

Also, I just noticed this: your example works. I. e. if I run big "ls" and
then "mc", then "altscreen" works. But if I type "mc" as first in command in
screen, then "altscreen" doesn't work (unlike stretch's version, i. e. "Screen
version 4.04.00 (GNU) 19-Jun-16")
