Windows notifications not displaying

[Mark Harkin]

Server: CentOS7 r21792
Client: Windows 10 r21792 (tcp or ws connection)

Notifications aren't displaying on Windows when using:

xpra control :0 send-notification  1 'foo' 'hello world' '*'

Confirmed working on CentOS7 client.
On Windows OpenGL warning on startup seems to display notification ok also.

I assume that this is a build from trunk? 2.4.x?

r21816 switches to the gtk notifier for all notifications. More fixes in r21814.
The native win32 notifier seems to be broken (new ticket: #2169), not sure when that happened.

[Mark Harkin]

Yes this was on trunk but I think this has be the case for some time.

On r21811 now getting an error on the client when connecting:

<Unicode console stdout>.write: NameError("free variable 'unicode' referenced before assignment in enclosing scope",)

Yes this was on trunk but I think this has be the case for some time.

Looks like it, I couldn't find an older version of the code that still worked.

On r21811 now getting an error on the client when connecting:
(..)

Is this a python2 or python3 build? What command line?
(I'm not seeing this error anywhere)

Seems to be only when using Xpra_cmd.exe, Xpra.exe seems to work fine.
(Python2 both Powershell and Command Prompt)

Also tested notifications and we can close this also.

I have committed a potential fix by mistake as part of r21822. Does that help?
I'm not seeing the problem with any builds and I am using Xpra_cmd.exe

Yes, no issue after r21822.

Thanks.
