            Bug ID: 17002
           Summary: Passing a directory to the "file" command gives wrong
                    error.
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: dje at google dot com

(gdb) file testsuite/gdb.base
testsuite/gdb.base: Success.
(gdb) file testsuite
testsuite: No such file or directory.

The first one fails, openp returns -1, but errno is zero so the error message
says "Success."

The second one fails, but I would have expected EISDIR or some such.

--- Comment #1 from Sergio Durigan Junior <sergiodj at redhat dot com> ---
After a quick investigation...

The first error is easily fixed (I have a patch for it).

The second error is a little more complex.  If GDB doesn't find a directory
separator in the filename (as is the case), then it tries to find in the $PATH
for the filename.  Only when it fails is that it decides to print the error.

Anyway, those are just my findings so far.
