Package: screen
Version: 4.3.1-2
Severity: normal
Apparently screen -r does some prefix-based matching. As a result, sometimes
even screen -r exact-name-of-session attaches to another session that is
more recent and whose name starts with the supplied string.
This might be caused by 80EXP_session_creation_time.patch.
To reproduce:
$ screen -d -m -S aaa sh -c 'echo aaa; sleep 3600'
$ screen -d -m -S aaabbb sh -c 'echo aaabbb; sleep 3600'
$ screen -ls
There are screens on:
10534.aaabbb (24/09/15 14:29:53) (Detached)
10496.aaa (24/09/15 14:29:49) (Detached)
$ screen -r aaa
[resumes aaabbb instead]
After some attaching/detaching, a “WriteMessage: Bad file descriptor”
error also happens intermittently after -r attempts. Repeating the -r
command reattaches successfully.

Version: 5.0.1-1
This issue is fixed in screen v5.
Upstream commit 5e4c7c5:
"Use fuzzy-matching for session names only if required"
changes session selection so an exact session-name match is preferred
over
prefix/fuzzy matches.
