I’m using fcgi.rb ruby-fcgi (0.8.7, according to the tarfile name, 0.8.5
according to the comment in the source) and lighttpd. Unfortunately,
lighttpd
can’t seem to shut down the ruby FastCGI servers:
25457 1 lighttpd CALL kill(0x2095, SIGTERM)
25457 1 lighttpd RET kill 0
8341 1 ruby18 RET accept RESTART
8341 1 ruby18 PSIG SIGTERM caught handler=0xbbbabdfc mask=())
8341 1 ruby18 CALL setcontext(0xbfbe7df4)
8341 1 ruby18 RET setcontext JUSTRETURN
8341 1 ruby18 CALL accept(0,0xbfbe8190,0xbfbe818c)
25457 1 lighttpd CALL unlink(0x806e800)
25457 1 lighttpd NAMI
“/u/cjs/co/dcity/instance.31041/sock/fastcgi-root-0”
It appears that the ruby interpreter, in ruby_signal() in signal.c, goes
and sets the SA_RESTART flag in the structure it passes to sigaction().
So, the accept syscall that it’s sitting in won’t be returned from until
the socket gets a connection, which is never going to happen because the
socket file is gone.
Anybody have any thoughts on what I can do about this silliness, short
of
modifying the Ruby interpreter?
And why does Ruby do this, anyway?
