[LTP] [PATCH] network/stress/http: Do not use SIGPIPE

[Petr Vorel]

Hi Akihiko,

Although curl really does not kill when testing manually, running:
curl -L -o /tmp/delete.iso http://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-DVD-x86_64-Current.iso

In another terminal this blocks:
killall -w -s SIGPIPE curl

But when I tested with nginx the original code with -s SIGPIPE) it works:

export HTTP_DOWNLOAD_DIR=/srv/www/htdocs/
PATH="/opt/ltp/testcases/bin:$PATH" http-stress.sh -i3

pgrep -a curl # nothing

Not sure what am I missing, but I don't see any problem to accept this patch.

Kind regards,
