Bug #: 28627
Summary: wfMakeUrlIndex throws "Undefined index: host" for file
links with more than two slashes
Product: MediaWiki
Version: 1.18-svn
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: General/Unknown
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
The function wfMakeUrlIndex() in includes/GlobalFunctions.php throws an error
if passed a file URI that has more than two slashes after "file://".
PHP Notice: Undefined index: host in <path>/w/includes/GlobalFunctions.php on
line 2636
This is because PHP's parse_url() function handles file URIs differently
depending on the number of slashes after "file:". If you have two slashes, you
get a 'host' array element:
print_r(parse_url('file:///whatever/you/like.txt'));
Array
(
[scheme] => file
[host] => whatever
[path] => /you/like.txt
)
but with three or more slashes, you don't:
print_r(parse_url('file:///whatever/you/like.txt'));
Array
(
[scheme] => file
[path] => /whatever/you/like.txt
)
This screws up all references to $bits['host'] in wfMakeUrlIndex.
I believe wfMakeUrlIndex() should handle file URIs specially, just as it does
"mailto" URIs today. It should accept ANY number of slashes after "file:",
because both IE and Firefox today accept these URIs (e.g., representing Windows
network shares).
