tcsh-6.21.00-sighup-deadlock.patch Normal file
View File

@ -0,0 +1,50 @@
tcsh can deadlock with itself if savehist is confgured with "merge" and
"lock", and two SIGHUPs are received in rapid succession. The
mechanism of the deadlock is the first SIGHUP triggers a rechist() and
while that rechist() is executing (and after it has created the lock
file), another SIGHUP triggers a another rechist() which then waits
forever for the lock the the first rechist() created to be released
(which will never happen).
