PHP Bug Type: Filesystem function related
Bug description: feof(FALSE) should return TRUE
Description:
------------
feof(bad_fd) returns FALSE, which indicates that the file descriptor
has more data. This is wrong in *every* case. It should return
TRUE (no more data), or throw a fatal error. More than a few sloppy
fools fail to test the result of fopen(), and blow your bandwidth
cap and/or hosting budget for a year by serving warnings when your
RSS source changes their DNS name.
Reproduce code:
---------------
<?php
$f = fopen ("http://dns.err/foo.html","r";); # ie. $f=FALSE
while (!feof ($f)) { # ie. !feof(FALSE)
$verse .= fgets($f, 4096);
}
fclose ($f);
echo "DONE";
Expected result:
----------------
Warning: fopen(): php_network_getaddresses: getaddrinfo failed: Name
or service not known in /home/andrewm/x.php on line 2
Warning: fopen(http://dns.err/foo.html): failed to open stream: No
such file or directory in /home/andrewm/x.php on line 2
Warning: feof(): supplied argument is not a valid stream resource
in /home/andrewm/x.php on line 3
DONE
Actual result:
--------------
Warning: fopen(): php_network_getaddresses: getaddrinfo failed: Name
or service not known in /home/andrewm/x.php on line 2
