            Bug ID: 17911
           Summary: gdb reports "/some/path/: Success" when trying to open
                    a directory
           Product: gdb
           Version: 7.8
            Status: NEW
          Severity: normal
          Priority: P2
         Component: cli
          Assignee: unassigned at sourceware dot org
          Reporter: nhaehnle at gmail dot com

Proposed patch

(This is on 7.8, but a quick glance at the source suggests it is also present
in more recent versions).

Consider the following transcript of a GDB session:

$ gdb
...
(gdb) file /home/
/home/: Success.
...

Clearly, it would be nice if the GDB output were more helpful. (The transcript
may seem trivial; however, this problem leads to significantly more confusion
in the context of KDevelop's gdb plugin.)

I am attaching a patch proposal which changes the behavior to:

(gdb) file /home/haehnle
/home/haehnle: Is a directory.
(gdb) file /home/haehnle/asdfs
/home/haehnle/asdfs: No such file or directory.
(gdb) file /dev/null          
/dev/null: Exec format error.

(The last case is a bit of an odd one out. Unfortunately, there is no
ENOTAREGULARFILE as far as I can tell, and ENOEXEC was the best I could come up
with.)
