* harbour/source/common/hbgete.c
* added suport for BSD systems
* harbour/contrib/examples/uhttpd/uhttpd.prg
! fixed private declaration - after last modification they were not
declared for threads at all
! fixed close procedure, s_aRunningThreads and s_aServiceThreads
where not protected at all in the moment when these variables
variables where used inside aeval() and other threads were
resizing them removing their pointers. In short word it was
in practice impossible to cleanly close uhttpd server without
GPF, deadlock or other bad side effects. I changed this code so
these arrays are modified only by calling procedure.
I do not know why it was written in such way but I guess it
was workaround for xHarbour bugs. In xHarbour is race condition
inside some functions like ThreadJoin() (RTE if thread finished
just before ThreadJoin(<pThID>)). Harbour does not have such
problems so I simply cleaned this code making it much simpler.
* reactivated hb_gcAll( .T. ) in the main loop for tests.
I made some tests with linux and current uhttpd works perfectly
without any problems with and without hb_gcAll( .t. ).
I haven't noticed any problems. I used this scripts to make
tests:
#!/bin/sh
function GT_UHTTPD()
{
while curl http://127.0.0.1:8082/ > /dev/null
do
if ! curl http://127.0.0.1:8082/serverstatus > /dev/null
then
exit
fi
# disable it if you want to increase traffic
if ! curl http://127.0.0.1:8082/info > /dev/null
then
exit
fi
if [ -f stop ]
then
exit
fi
done
}
for i in `seq 10`
do
GT_UHTTPD &>/dev/null &
done
wait
on three CPU machine. Please make some test with other systems.
