The segfault is one of
the problem… It only segfaults after you have read a device-page.
owhttpd --foreground
--error_level=9 -s 3011 -p 3012
owserver --foreground
--error_level=9 --fake 10,10 -p 3011
kill –INT <owserver>
works perfect
owhttpd --foreground
--error_level=9 -s 3011 -p 3012
owserver --foreground
--error_level=9 --fake 10,10 -p 3011
lynx –source http://localhost:3012/uncached/
kill –INT <owserver>
works perfect..
owhttpd --foreground
--error_level=9 -s 3011 -p 3012
owserver --foreground
--error_level=9 --fake 10,10 -p 3011
lynx –source http://172.20.1.101:3012/10.67C6697351FF
kill –INT <owserver>
owserver segfaults since the
memory/stack is corrupt.
I’m playing the
Swedish championship in pinball this weekend, and I qualified for the finals
today. Will not have home to look at the bug until Monday… Have you tried
to trace down the failing free() calls?

owserver bug
Christian,
I can't replicate this error. (Current CVS version, AMD64 platform).
Used your example invokation exactly, except didn't run gdb.
I assume you featured only a part of the output, my listing starts with
address, not temperature.
I do notice a segfault whenever I Cntr-C out of
owserver. That isn't the problem you're noting. owhttpd exits
gracefully.
I'll try running wget on owhttpd overnight to see if this is an intermittent
problem.

I have worked with the signal handling and made some adjustments... But I
recently found out some bad free() calls in owserver/owlib.
It only occurs when I start owserver & owhttpd.
(owserver & owdir works fine!?!)
owserver --foreground --error_level=9 --fake 10,10 -p 3011
owhttpd --foreground --error_level=9 -s 3011 -p 3012
View a sensor directory and you will get some errors in owserver about:
"free(): invalid pointer 0x8b66eb8!"
And after that I can't stop the process correctly.
I don't have time to search for the problem right now, and I'm not sure if I
will have much spare time this weekend either... that's why I send an email
about it.
