Hi there!
Here is my fix to retrieve correct file information on POSX systems when along the path traversal a directory has no executable flag.
From
stat(2)
manpage:At the moment this is an incomplete fix: it breaks usage of
lstat(2)
on POSIX systems, due to change of the function signature passed to_file_info_()
.Kindly provide feedback on how to proceed. IMHO the usage of a function pointer passed as argument of file_info is a design burden: a simple flag can be used.
ciao
p.s. for the impatient, a quick non-breaking fix is applied in the lfs version shipped in my software.
