Summary: libscreen Invalid Magic
Product: Sorcery
Version: Untargetted future release
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P2
Component: subroutines
AssignedTo: sm-sorcery-bugs AT lists.ibiblio.org
ReportedBy: pmahon AT sourcemage.org


There is a race condition in gnu screen which results in the following
message:
Invalid message (magic 0x20747361)

This happens if too many commands are sent to the screen too quickly. The
addition of sleeps seems to have fixed the race condition, but slower machines
may still have a problem. SCREEN_ANTI_RACE_SLEEP is the (possibly decimal)
number of seconds to sleep, a value around 0.2 seems to fix the problems for
machines faster than 1GHz or so.

When someone has time, it would be good to see if this race condition can be
elimiated, and submit the patch upstream.
