[Octave-bug-tracker] [bug #48105] function "glob" oddities with trailing "/"

[Rik]

Follow-up Comment #2, bug #48105 (project octave):

I'm pretty sure this is a gnulib quirk.  I created the same test directory
containing two directories and two files


ls -F
d/  dir/  f  file


I then used perl, which I believe is linked against the system library version
of glob, to check.


perl -de 42
@a = glob ('f*');
X a
@a = (
   0  'f'
   1  'file'
)

@b = glob ('f*/');
X b


So, the first question is why gnulib isn't just using the system version of
glob that is defined in glob.h, as long as it is reasonable.  I thought gnulib
was smart enough not to substitute C code where it didn't have too.  Second,
since it appears to be using it's own implementation, why doesn't it have it
right?

Just to check, I went and edited oct-glob.cc.  I changed


#include <glob.h>


to 


#include "/usr/include/glob.h"


I then took the gnulib:: namespace decorator off the call to glob and
globfree.  After re-compiling, Octave returns an empty cell array for the
pattern 'f*/'.
