Bug description: Socket reading functions always timeout
While performing read functions on a socket, fread,fgets,fgetss, with the timeout
value set on the socket If a timeout occurs all subsequent calls timeout immediately.
example:
$s = fsockopen("localhost",25);
socket_set_timeout($s,0,100000);
$rply = fgets($s,129); # "220 server.domain SMTP server xyz v1.0"
fputs($s,"HELO my.domain\r\n");
$rply = fgets($s,129); # "250 Welcom my.domain"
$rply = fgets($s,129); # no data so it times out
fputs($s,"NOOP\r\n");
$rply = fgets($s,129); # times out; data is available
fputs($s,"QUIT\r\n");
$rply = fgets($s,129); # times out; data is available
fclose($s);
Removing the fgets that doesn't get any data will cause the program to run as
expected. Also, moving the fgets to any line will cause all lines below it to timeout
even when there is data.
I tracked the the problem down in ext/standard/fclose.c to being while loops that use
the sock->timeout_event variable as a condition without first reseting the variable to
an appropiate value. Below is a context diff that fixes the problem.
