[1.7.0 HEAD]: Cygwin no longer encoding/decoding names on managed mounts

[Nicholas Wourms <nwourms at gmail dot com>]

Hi All,

I'm not sure when this cropped up, but it happened sometime after the
great "win 9x" code purge. The problem is that the Cygwin dll no longer
decodes or encodes file/directory names on managed mounts.


Steps to reproduce (WinXP SP2 x32):
-----------------------------------
1) mkdir -p /usr/src2
2) mount -b -s -o managed C:\\cygwin\\usr\\src2 /usr/src2
3) cd /usr/src2
4) mkdir -p FOO
5) ls -1 /cygdrive/c/cygwin/usr/src2

1.5.25(0.156/4/2) results:
--------------------------
Expected: %46%4F%4F
Actual: %46%4F%4F

1.7.0(0.179/4/2) results:
-------------------------
Expected: %46%4F%4F
Actual: FOO


For this test, I setup a fresh, default Cygwin install on another
machine. The Cygwin dll which was used was from the 1.5.25-7 package. I
ran the test and everything worked as expected. However, on the machine
with the Cygwin dll compiled from cvs HEAD, it did not. Running strace
on the "mkdir -p FOO" operation seems to confirm that the munging gets
skipped somewhere in the normalize_posix_path function.

Anyway, that's all I could come up with for now. Anyone else seeing
this? I'll see if I can't do more later on this week when I have more time.

Cheers,
Nicholas
