Title::quickUserCan (   $action)

Can $wgUser perform $action on this page? This skips potentially expensive cascading permission checks.

Suitable for use for nonessential UI controls in common cases, but not for functional access control.

May provide false positives, but should never provide a false negative.

Parameters
string$actionaction that permission needs to be checked for
Returns
boolean

Title::secureAndSplit ( )
private

Secure and split - main initialisation function for this object.

Assumes that mDbkeyform has been set, and is urldecoded and uses underscores, but not otherwise munged. This function removes illegal characters, splits off the interwiki and namespace prefixes, sets the other forms, and canonicalizes everything.

Returns
bool true on success

Pages with "/./" or "/../" appearing in the URLs will often be unreachable due to the way web browsers deal with 'relative' URLs. Forbid them explicitly.

Magic tilde sequences? Nu-uh!

Limit the size of titles to 255 bytes. This is typically the size of the underlying database field. We make an exception for special pages, which don't need to be stored in the database, and may edge over 255 bytes due to subpage syntax for long titles, e.g. [[Special:Block/Long name]]

Normally, all wiki links are forced to have an initial capital letter so [[foo]] and [[Foo]] point to the same place.

Don't force it for interwikis, since the other site might be case-sensitive.

Can't make a link to a namespace alone... "empty" local links can only be self-links with a fragment identifier.
