Bug description: recv in fastcgi never returns when server doesn't pad to size
of 8
Description:
------------
line 624 of sapi/cgi/fastcgi.c contains:
while (recv(req->fd, buf, strlen(buf), 0) > 0) {}
with buf being an array with 8 elements.
With the server doesn't pad all packets to the size of 8
(Which is suggested but not required by the fast-cgi spec), this causes
frequent lockups and failed requests. (Without that padding, I have no
idea about with it).
My fix was simple - change strlen(buf) (which returns 8), to 1, so it will
read any excess bytes at the end and cleanly close and continue on, even if
it's not a multiple of 8 bytes.
Thank you for php!
Expected result:
----------------
fast-cgi padding to be read and thrown out, requests to close.
Actual result:
--------------
request tends to lock up on recv when packets arn't a multiple of 8 in
size.
