"[Errno 9] Bad file descriptor" on testing with ab #1

Open mrkafk opened 10 years ago

mrkafk commented 10 years ago

In one console:

(w2)d7 192.168.56.101 ~/w2/tmp/weightless-core/weightless/examples % ./httpserver.py

In another console:

d7 192.168.56.101 ~ % curl http://127.0.0.1:8080/
Hello!d7 192.168.56.101 ~ %

It works. Then:

d7 192.168.56.101 ~ % ab -n 300 -c 50 http://127.0.0.1:8080/

Hi,

Sorry for my late reply.

I looked into your problems and I'll reply to them separately.

For the problem below, I see you are using GCC 4.7 and Python 2.7 on Linux 3.2. The handling of sockets is usually a bit nifty and depends on the platform. Therefor I would need to these versions running. I haven't at the moment, as all my development work is on either Debian of RedHat, which both lag behind a bit.

However, we will be switching to Debian Wheezy shortly and at that point it becomes a necessity for us to work, so it will be fixed soon, although I regret that I cannot do it right-away.

Erik
