[Bug 22418] New: Wine apps executed from a dynamically mounted device leave open files after being closed.

http://bugs.winehq.org/show_bug.cgi?id=22418

Summary: Wine apps executed from a dynamically mounted device
                    leave open files after being closed.
           Product: Wine
           Version: 1.1.42
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I am running openSuSE 11.2 with Wine-1.1.42 and use the PortableApps off of a
USB Passport disk drive. I am noticing that when I try to close applications
such as Firefox or Thunderbird, also running under Wine, that the processes for
Thunderbird, Firefox, PortableApps, and Wineserver are leaving files open and
not properly closing them (Observed with lsof /media/My\ Passport after closing
the apps) This in turn prevents the disk drive from being able to be dismounted
and forces me to kill the associated processes. Of course that is dangerous and
can lead to file corruption.
> From my observations, this is only happening when running an app under Wine,

when the app is executed from a dynamically mounted device. It does not occur
when the app is executed from a permanently mounted disk drive...

No, not always, although I have seen them show up on occasion as a defunct
process when I give a ps -aux command. When that happens it is not a transitory
state either but will persist until I kill the process with a kill -9 command..

Other symptoms I have noted, and should point out, is that there have been
occasions when I tried to dismount the USB drive, neither ps nor lsof have
reported anything amiss, but the umount command would still be refused with a
"Device Busy" message. Sometimes however just lsof would report open files
remained, and I will kill the associated process despite the fact that ps was
not showing it. Sometimes that works, sometimes not.

I know that the only thing I had done, in these cases, was to run
FirefoxPortable or ThunderbirdPortable under PortableApps, all under Wine, and
all were "closed" . Nothing else could/should have been using the device, and
simply waiting for awhile would not change this...  When I can't find a process
to kill, at that point my only option has been to reboot and hope that the
shutdown process would safely dismount the USB drive...

This sounds like a kernel bug to me. If a process some how mysteriously keeps
files open when it's killed and not even shown in 'ps -ef' (or any other ps
output that shows all processes) then it's something really messed up inside
kernel.

I think it is wrong and unprofessional for you to simply close this bug report
and point fingers at someone else. You do NOT KNOW whether this is a kernel bug
or not, and simply took a guess, based upon a few observations on my part, none
of which could possibly clearly identify where the problem resides. All you
have done by attempting to disown this bug is to leave me in a difficult
position to try an find a solution.

I have reported this bug because it is clearly related to Wine and possibly
it's interactions with both the kernel and with an application running under
Wine. I have NOT observed similar symptoms with other apps, as would probably
happen if this were truly a kernel bug.

This is a serious bug which could cause potential data loss for users. The
developers of Wine should take responsibility to at least clearly determine,
whether the bug resides within Wine, or with another subsystem, i.e. the
kernel, and work with me, and the developers of any other subsystem involved,
to clearly identify the problem and to find a resolution.

Please reconsider your decision to close this bug report, and do not simply
blow me off with a half-hearted guess.

I'm repeating again. _If_ the process is closed, and Wine is no longer running
it can not be anything related to Wine.

Wine is a 100% user process it can not magically keep files open if it's not
running.

Closing. File bug with your distro.
