[Bug 35495] New: sharing violation and prompt for copy /B file1+file2 file1

http://bugs.winehq.org/show_bug.cgi?id=35495

Bug ID: 35495
           Summary: sharing violation and prompt for copy /B file1+file2
                    file1
           Product: Wine
           Version: 1.7.10
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
          Assignee: [e-mail]
          Reporter: [e-mail]
    Classification: Unclassified

copy /B file1+file2 file1

(to do append in a rather old nmake MSVC build script)

results in sharing violation and prompts, and error. Obviously, under genuine
windows, there is no prompt to confirm, nor the sharing violation message.

The actual behavior is this:

-------------
> copy /B file1+file2 file1

Overwrite file1? (Yes|No)yes
Sharing violation.

Overwrite file1? (Yes|No)yes
> copy file1+file2 file1

Overwrite file1? (Yes|No)yes
err:cmd:WCMD_ManualCopy Unexpected failure writing to L"file1", rc=6
Invalid handle.

Overwrite file1? (Yes|No)yes
-----------

The expected behavior should be silent for /B .

The /B switch has actually nothing to do with a prompt (or silence). It just
signifies binary mode, which is fine in your case.

To avoid a prompt, you should use the /Y switch.

As for the main issue, I've sent a patch that should fix it:

Actually my patch fixes your prompt problem as well, since appending to a file
does not cause a prompt.

So, this is fixed in 064508c0dd7bb331d581de77bebec62db2025e57.
