[Bug 26549] New: GomezPEER fails to set processor priority

http://bugs.winehq.org/show_bug.cgi?id=26549

Summary: GomezPEER fails to set processor priority
           Product: Wine
           Version: 1.3.16
          Platform: x86-64
               URL: http://lastmile.gomez.com/PEERInstall.exe
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

GomezPEER sets its background process (an instance of java.exe) to the lowest
(idle) priority in Windows.  It fails to do so under Linux.  Does Wine lack the
ability to set process priorities, perhaps?

Apologies if a similar bug is already open but I could not find one.

On newer systems this is not a problem, but on older system the PEER can
consume 100% CPU while processing.  The app is designed so that performance of
the PC is not affected, which of course it isn't under Windows (save the usual
Windows-related problems) but it is under Wine.

I'm not sure if I/O priority is also set.

The following does not work as a workaround:

$nice -n19 wine ~/blah/GomezPEER.exe

because this then sets all the Wine components to -n19 and can badly affect the
performance of other apps running under Wine.

Instead, the workaround I use is:

$wineserver -p15
$nice -n19 wine ~/blah/GomezPEER.exe

This way the wineserver remains at normal priority.  winedevice.exe in this
case still receives -n19 priority, however.

I don't think this bug will ever get fixed, unless it's fixed in POSIX.

POSIX allows user space applications to lower their niceness but you cannot
raise it (you will receive the "permission denied" error).

In Windows it's possible to restore "niceness" to the "Normal" level.

Lowering the niceness should still be supported IF possible.

Raising the priority to "normal" is supported under Ubuntu. I don't know about
other OS but IIRC PC-BSD 9.x and OpenIndiana had no issue with this either.

In fact, Ubuntu's PPA Wine patches Wine to allow this, and it works perfectly.

Is this feature added or not? BOINC needs this.

https://github.com/wine-compholio/wine-staging/wiki/Environment-Variables#Re...

Wine said there is "optional" real time priorities support but what about
setting it to lower/lowest priority?

The built-in taskmgr.exe felt like does nothing...

The first patch landed in ab3c0a3e0a7b8f9fc1eb703b2e4f2133ef3ebf0d (wine 3.3)
The second is still being carried in staging. 
Should the bug status be updated?
