Bug description: getallheaders() possible bug.
getallheaders is this :
PHP_FUNCTION(getallheaders)
{
array_header *env_arr;
table_entry *tenv;
int i;
if (array_init(return_value) == FAILURE) {
RETURN_FALSE;
}
env_arr = table_elts(((request_rec *)
SG(server_context))->headers_in);
tenv = (table_entry *)env_arr->elts;
for (i = 0; i < env_arr->nelts; ++i) {
if (!tenv[i].key ||
(PG(safe_mode) &&
!strncasecmp(tenv[i].key, "authorization", 13))) {
continue;
}
if (add_assoc_string(return_value, tenv[i].key, (tenv[i].val==NULL) ? ""
: tenv[i].val, 1)==FAILURE) {
RETURN_FALSE;
}
}
}
Using the example from the docs :
<?php
$headers = getallheaders();
while (list ($header, $value) = each ($headers)) {
echo "$header: $value<br>\n";
}
var_dump($HTTP_SERVER_VARS['HTTP_ACCEPT_ENCODING']);
?>
I receive this :
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
application/vnd.ms-powerpoint, application/vnd.ms-excel,
application/msword, */*
Accept-Language: bg
Connection: Keep-Alive
Host: vanity.masq
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
NULL
I thought that to get if the browser has capability of encoding it must be
in $HTTP_SERVER_VARS['HTTP_ACCEPT_ENCODING']. Why I decided that?
Snippet from zlib.c :
if (ZLIBG(ob_gzhandler_status)==-1
|| zend_hash_find(&EG(symbol_table), "HTTP_SERVER_VARS",
sizeof("HTTP_SERVER_VARS"), (void **) &data)==FAILURE
|| Z_TYPE_PP(data)!=IS_ARRAY
|| zend_hash_find(Z_ARRVAL_PP(data), "HTTP_ACCEPT_ENCODING",
sizeof("HTTP_ACCEPT_ENCODING"), (void **) &a_encoding)==FAILURE) {
/* return the original string */
*return_value = **zv_string;
zval_copy_ctor(return_value);
ZLIBG(ob_gzhandler_status)=-1;
return;
}
The sniff from Naviscope :
GET http://myserver.masq/proxy/getall.php HTTP/1.1
Accept: */*
Accept-Language: bg
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
Host: vanity.masq
Proxy-Connection: Keep-Alive
