[ANNOUNCEMENT] screen-4.6.2-3 (test)

[ANNOUNCEMENT] screen-4.6.2-3 (test)

[Andrew Schulman]

screen-4.6.2-3 is now available as a test release in Cygwin. This release
includes a small change to the default /etc/screenrc, that has been
reported to fix a screen corruption problem that some users - okay, Shaddy
:) - have reported after detaching from screen[1,2].

If you're a screen user, it'd be helpful if you'd first determine if you
have the symptom: the cursor appearing in the middle of the terminal
buffer, intermingled with other lines of text, after you detach or exit a
screen session.

If you do have that problem, please install the test release and see if it
fixes it. Be sure that your /etc/screenrc is the same as the new default,
/etc/defaults/etc/screenrc. Or if you've customized /etc/screenrc, you can
just comment out the lines:

#
# Do not use xterms alternate window buffer.
# This one would not add lines to the scrollback buffer.
termcap xterm|xterms|xs ti=\E7\E[?47l
terminfo xterm|xterms|xs ti=\E7\E[?47l

Then report here what you found.

Even if you don't have the screen corruption problem, it'd be helpful to
test this release and report here whether it causes any problems for you.

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells. Each virtual
terminal provides the functions of the DEC VT100 terminal and, in addition,
several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022
standards (e.g., insert/delete line and support for multiple character
sets). There is a scrollback history buffer for each virtual terminal and a
copy-and-paste mechanism that allows the user to move text regions between
windows. When screen is called, it creates a single window with a shell in
it (or the specified command) and then gets out of your way so that you can
use the program as you normally would. Then, at any time, you can create
new (full-screen) windows with other programs in them (including more
shells), kill the current window, view a list of the active windows, turn
output logging on and off, copy text between windows, view the scrollback
history, switch between windows, etc. All windows run their programs
completely independent of each other. Programs continue to run when their
window is currently not visible and even when the whole screen session is
detached from the user's terminal.

Many thanks for this :-) Sorry I went silent in the subsequent
discussion. I became busy, then went travelling for a week. I'll test
this release. Report back.

Whilst I'm at it, I'm not sure if others were able to reproduce. But the
steps to reproduce for me were really quite simple. In mintty, hit enter
a few times to get the prompt off of the top (and create a bit of
terminal history for mintty to restore), just run a screen session
(simple 'screen' command line is sufficient). Hit enter at the new
session prompt a few times so that the cursor is a few lines down from
the top. Type exit (or ctrl-d to detach) and see the message:

[screen is terminating]

at the top, with the original mintty prompt flashing intermixed with the
restored terminal history.
