           Summary: kernel/console: no more EOF handling.
           Product: Wine
           Version: 1.3.2
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wineserver
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: hoehle at users.sourceforge.net

^D (^Z in native) used to be able to end the session with my
interactive MCI shell (bug #20232, comment #9).  What it does is:

 ret = ReadFile(hin, inbuf, sizeof(inbuf)/sizeof(inbuf[0])-1,
                &received, NULL);
 if(!ret || !received) break;

^D signals EOF in UNIX (more precisely, it immediately returns the
pending read(), which is interpreted as EOF when there is no more
input on the line).  ^Z is EOF in MS-Windows, since MS-DOS times.

Presumably since Eric Pouech's console patches, EOF is not recognized
and I must ^C the program.

BTW, native's ^Z handling differs among versions.  In win95, ^Z
immediately sends an EOF to the app; since w2k you need ^Z + Return.

^Z is not honoured in Wine (after using "stty susp ^y").

Alternatively instead of wine mcishell.exe,
using ^C in an mcishell started inside "wine cmd" yields:
^Cfixme:console:CONSOLE_DefaultHandler Terminating process 8 on event 0
fixme:console:CONSOLE_DefaultHandler Terminating process 1c on event 0
err:console:WCEL_Get hmm bad situation
mci.c:1376hoehle:~/Bugs$ : GetLastError: 0 <= that's from mcishell,
                                           so it was not aborted!?!
          ^^^^^^^^^^^^^^ bash prompt gets in between
mcishell: 2 tests executed (0 marked as todo, 1 fai <= nothing more

I just noticed console error #2:
wine wineconsole cmd (as the usage() text says)
opens a virtual desktop but no console window appears.
That desktop window cannot be activated.
Clicking the close button produces Wine's "kill app" requester after a couple
of seconds. Accepting yields a mini backtrace in the terminal:
0x9d50fd0:1: Fd unix_fd=71 user=0x9db3320 options=00000020
0x9db3320:1: Console screen buffer input=0x9d53fe0
0x9d50f10:1: Fd unix_fd=65 user=0x9d53fe0 options=00000020
0x9d598a0:1: Event manual=1 signaled=0 name=""
0x9d53fe0:1: Console input active=0x9db3320 evt=(nil)
That does not look like a typical backtrace from Wine.
Ah, it's from server/{event,console}.c
I should probably open a separate bug report for that one.

I'm using Ubuntu Intrepid.
