I've noticed that POL creates playonlinux.log in each wineprefix. Sometimes, because of harlmess wine errors and "fixme" messages it's getting filled quite quickly. For example, SpaceEngine creates 3 mb of same error message in just 2 minutes. I've tried to put "-all" debug flags in settings, but apparently it only affects debug mode. Is there a way to disable logging at all?

When not in debug mode PlayOnLinux uses -all debug flags, so that's not normal. What is being logged exactly?

I didn't have the time to check, I can't guarantee it'll be supported forever (it should work for any 4.x version at least) but you can try:

Configure button > (select shortcut) > Miscellaneous tab > Command to run before the program is launched:

export LOGFILE=/dev/null

Unfortunately I cant provide playonlinux.log from my Space Engine now installation since I'm on a different system now, but I have logs from running world machine on mint 17 installation under virtualbox, and, as I understand, playonlinug.log have logs from both POL itself and wine, so it's still being filled with stuff like logs of running world machine itself every time.

VERR_INVALID_HANDLE (-4) - Invalid loader handle.

it crashes, but it's because I'm running it in virtualbox.

Also, using LOGFILE=/dev/null, does that mean that logfile is still being written to my hard drive and then being removed? I'm using ssd and trying to minimize unnecessary drive I/O as much as possible.

Ok, so those are logs from PlayOnLinux (first line) and logs from the game itself, none from Wine, as expected with -all flags

Also, using LOGFILE=/dev/null, does that mean that logfile is still being written to my hard drive and then being removed? I'm using ssd and trying to minimize unnecessary drive I/O as much as possible.

If it works no logs will be written.

Thank you for quick response, if I run POL itself with "LOGFILE=/dev/null", will it work for all applications launched from playonlinux?

LOGFILE=/dev/null playonlinux

Also, I have another problem, how exactly does this "Command to run before the program" function work? I have optimus laptop and using bumblebee. On the official FAQ it's stated that I should put "optirun" or "primusrun" commands in that field but it seems that instead of appending the content of that field to start of command, it runs it separately.

How it's supposed to be if I put "primusrun" in that field:

primusrun wine "World Machine.exe"

How it actually is:

primusrun

wine "World Machine.exe"

I've tried to put some random commands into that field (for example, thunar, xfce4-terminal or mousepad) to see if it's actually appending it to start of the command, but instead was getting just empty instances of these applications launched without them opening anything, just like if I run it from start menu.

No, that variable is just set internally before running Wine

PlayOnLinux indeed runs the commands in this field separately; If you want to actually prefix the command with something, use

export BEFORE_WINE='something'

As to how to use it to run primusrun, you tell us, we tried to add support in PlayOnLinux 4.1.0 and had to remove it because it didn't work (and we don't have the hardware to debug the situation)
