Hi
I have been helping some people to debug a SIGALARM related crash
induced by using pl/perlu http get functionality
I have been so far able to repeat the crash only on Debian 64 bit
computers. DB create script and instructions for reproducing the crash
attached
The crash is related to something leaving begind a bad SIGALARM handler,
as it can be (kind of) fixed by resetting sigalarm to nothing using perl
function
So doesn't this look like a bug in the perl module that sets the signal
handler and doesn't restore it?
What happens if you wrap the calls to the module like this?:
{
local $SIG{ALRM};
# do LWP stuff here
}
return 'OK';
That should restore the old handler on exit from the block.
I think if you use a perl module that monkeys with the signal handlers
for any signal postgres uses all bets are off.
