           Summary: Winbench 96 disk test fails during recursive directory
                    deletion; bug in INT21_FindFirst/FindNext?
           Product: Wine
           Version: 1.1.13
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dos
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com


Install and run Ziff-Davis PC Benchmarks WinBench 96
(on the Winstone 32 cd-rom).
Start it with
  cd .wine/drive_c/ZDBENCH/WB96
  wine WB96
Get past the hangs described in bug 12267 by killing and restarting twice.

Run the "Disk Tests".  Get past the abort 

"A DOS file operation that was supposed to fail succeeded during the test.
The following information is for ZDBOp use:
Drive: C  Operation: GetFileAttrib
Script Location: 0d0b11 0
Pathname(s): C:\~WBDM.TMP\ZDBENCH\WS96.B03\WORK\PDOX50\"

by applying the patch
http://www.winehq.org/pipermail/wine-patches/2009-January/068579.html

The test runs for a long time, then tries to delete its temporary
directory, C:\~WBDM.TMP, but fails with the dialog
and the app aborts with

"A DOS file operation failed during the test.
The following information is for ZDBOp use:
Drive: C  Operation: DeleteTestDir
Pathname(s): SB, ???????????
Working Dir: ~WBDM.TMP
Int 21 Function: 3a 00 CF: 1 Expected CF: 0"

Looking at the log, it seems as if Wine trips over its shoelaces
when the app is doing its recursive directory list, 
and does not tell the app about one directory, 
C:\~WBDM.TMP\MGA\CPANEL.  As a result, the app doesn't
delete its contents, and when the app then tries to 
delete C:\~WBDM.TMP\MGA, it fails with 'directory not empty'.

INT21_FindHelper looks awfully tricky.  It seems to have
a loop to skip over some directory entries, and maybe this
is firing improperly here.  The code seems to date from
2003-11-14, mostly written by Eric Pouech in 
http://source.winehq.org/git/wine.git/?a=commit;h=8ca6cadab1ebb386f1dfa2e47c609ba5f43cc394
and touched up by Alexandre same day in
http://source.winehq.org/git/wine.git/?a=commit;h=adfa5e101fc2e01d4276c3f3ee4ae373d5af7c8a
