[Openmcl-devel] ENSURE-DIRECTORIES-EXIST and DIRECTORY on Windows

Hi!

First, I want to appreciate the work you have put into the Windows port
of Clozure CL. Thanks.

At the end of this mail is a patch which attempts to make CCL's
DIRECTORY and ENSURE-DIRECTORIES-EXIST functions nicer on Windows.

(I am using 1.3-r11949 on Windows XP SP2.)

Most of the changes typically involve the addition of the :DEVICE
component for to make the functions `drive aware'---if you will.

For 1 and 2, the `context' is:

? (PATHNAME-DEVICE (CURRENT-DIRECTORY)) => C



1.

? (ENSURE-DIRECTORIES-EXIST "D:/dir1/dir2/") => creates "C:/dir1/dir2/"
instead.



2.

? (DIRECTORY "D:/dir1/dir2/*.*") => NIL (despite having files in
D:/dir1/dir2/).



3. I have a file tree with the following structure:

D:.
|   init.bat
|
+---.dir2
|   |   .file3
|   |   file1.txt
|   |   file2
|   |
|   +---.dir1-2
|   |       .file5
|   |       file3.txt
|   |       file4
|   |
|   \---dir1-1
|           .file3
|           file1.txt
|           file2
|
\---dir1
     |   .file3
     |   file1.txt
     |   file2
     |
     +---.dir1-2
     |       .file5
     |       file3.txt
     |       file4
     |
     \---dir1-1
             .file3
             file1.txt
             file2


? (DIRECTORY #P"D:/sources/lang/lisp/ccl/tests/**/.dir2/" :directories t))
=>
'(#P"/sources/lang/lisp/ccl/tests/.dir2/"
#P"/sources/lang/lisp/ccl/tests/.dir2/.dir2/"
#P"/sources/lang/lisp/ccl/tests/.dir2/.dir1-2/.dir2/"
#P"/sources/lang/lisp/ccl/tests/.dir2/dir1-1/.dir2/"
#P"/sources/lang/lisp/ccl/tests/dir1/.dir2/"
#P"/sources/lang/lisp/ccl/tests/dir1/.dir1-2/.dir2/"
#P"/sources/lang/lisp/ccl/tests/dir1/dir1-1/.dir2/")

If I understand the Spec well, I expected:
#P"D:/sources/lang/lisp/ccl/tests/.dir2/"

Regards,
Martin.


Patch: (In the expected format, I hope.)
