So, I'm trying to execute a script on every request. I know how that sounds, this is for development environment.
I've added this to my nginx config access_by_lua_file "/opt/nginx/git-magic.lua";
git-magic.lua contains local status = os.execute('/opt/nginx/git-magic.sh')
And git-magic.sh contains: echo hello >> /tmp/git-magic
The issue is:
Whenever I hit any URL, I get the following in the nginx error log: 2012/09/27 15:35:48 [alert] 3241#0: waitpid() failed (10: No child processes)
Any ideas what I might be doing wrong?

Have you checked the obvious? Can nginx user access lua file? can nginx user write to /tmp/ ?

Lua can access git-magic.sh, git-magic.sh writes the right thing to /tmp/git-magic

See if there's an apparmor.d file for nginx. I had a problem convincing dhcpd to run a file when an address is requested, because apparmor was blocking it.
