Does PHP know that?
This is actually a little complex. A couple of underlying questions:
- Does the Lion PHP know its working with a case insensitive file system?
- Is there any hardcoded attempt to load the plugin?
and three things:
- DokuWiki itself only loads plugins based on the file names it reads from the
plugin directory. I.e. if only DokuWiki core is loading plugins the error
should not be able to occur.
- Plugin files are loaded using include_once. If PHP knows its using a case
insensitive file system the error should not be able to occur.
- If custom code is attempting to load the plugin component using a hard coded
name (e.g. "misra_attributevalue") and PHP thinks the file system is case
sensitive and the filename is a case insensitive match but not a case sensitive
one (i.e. dokuwiki is loading misra_attributeValue), you have the possibility
of the error you're seeing.
Plugin loading has been completely revamped for Angua. My reading of the code
is the error you're seeing could no longer happen.
