Bug description:get_headers( ) loops on localhost
Description:
------------
First I want to say I have an offer of 2x1 bugs. I will start with a bit of
history.. (for some reason) I have a test server added to my
system32/drivers/etc/hosts. Ex: 127.0.0.1 testserver.com
and I thought the problem can be the name of something like that, and
deletind the line doesn't solve the problem, and then I realized that the
problem is the function inself with the localhost.
Is almost understandable becouse it try to get the self headers over and
over again. Almost like: function get($headers){return get($headers);}
The subsequent problem is that is bypassing the time limit of the script,
30 seconds (or whatever time limit is) and the script when reach the limit,
the limit is restarted and run again for few minutes 'till the browser stop
it.
The error.log will have thousands of line with the error limit..
The documentation doesn't say nothing about localhost.
Speaking of error log, here come the second bug. NOTE: only happens with
the bug above ! That why I put together. Ok.. lets see..
For production (like almost everybody, i guess) I use:
ini_set('log_errors', false);
ini_set('display_errors', false);
Ok.. When I try to see the error returned by the above bug with
"display_error true", nothing is showed, and ONLY when "log_errors are
true" it show me the error "Time limit 30 seconds etc...", also it show me
the error with "display_errors false" too ! Something strange there..
Maybe is becouse the script running foreaver, when the browser it stop it,
the php does have nothing "prepared" to show.. and must get something from
the error.log to display something to the browser
To finish, maybe the second is the subsequent of the first bug (almost sure
it is), so dont give to mush importance to that, and fix just the first
one.
Test script:
---------------
<?php
var_dump(get_headers('http://localhost'));
Expected result:
----------------
The list of all headers..
or some error like "The php can not get the headers from localhohst" :D
Actual result:
--------------
The script run forever and ever.. (what a happy ending) ..'till the browser
dies.. (what a sad ending)
