Description Ling Li 2005-03-31 19:47:13 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2

Description of problem:
This is a known bug, see, the 3rd bullet. 

To repeat briefly, if a directory d being searched for subdirectories contains plain files and symbolic links to other directories, but no true subdirectories, d will be considered a leaf directory, i.e., the symbolic links will not be followed. You can work around this problem by creating an empty dummy subdirectory in d. Then d will no longer be a leaf, and the symlinks will be followed.

I haven't looked at the actual code for this part, but there is one line in this page reading "You can disable the trick by undefining UNIX_ST_LINK in kpathsea/config.h. (It is undefined by default except under Unix.)" So I guess the quick fix is to disable UNIX_ST_LINK on Fedora Core.

However, if the search performance is the main concern, the code for kpathsea has to be modified. I don't have a solution.

I'm not sure whether the undefinition of UNIX_ST_LINK will help somehow as I
grepped all teTeX sources, including kpathsea and found no checks or definitions
of this macro in teTeX-3.0 and teTeX-2.0.2 at all.

I found the UNIX_ST_LINK macro is only noted in the documentation...
