Description Mikkel Kruse Johnsen 2014-03-27 02:28:58 UTC
After updating to Mono 3.2.8 printing under Windows (7) with Gtk# is not working. It worked before, with Mono 3.0.2 (I only updated Mono, not Gtk#)

The last time I had this error (many years ago, I had to add the [STAThread] to my main funtion.

The program just hangs, no exception or any information.
Comment 1 Mikkel Kruse Johnsen 2014-03-28 07:16:22 UTC
I have testet with the official Mono installer 3.2.3 aswell and it breaks printing with Gtk#

The official Mono installer 3.0.10 works fine.

(Could not find any installers in between)
Comment 2 Zoltan Varga 2014-03-28 17:00:22 UTC
-> gtk#
Comment 3 Mikkel Kruse Johnsen 2014-03-31 03:36:35 UTC
Zoltan, this has nothing to do with Gtk#. 

This is a Mono problem.
Comment 4 Andres G. Aragoneses 2014-03-31 09:41:53 UTC
If you're sure this is a mono bug and regression, you could try bisect the commit that caused it, given that you know a working version and a non-working one.
Comment 5 Mikkel Kruse Johnsen 2014-03-31 09:57:05 UTC
I am pretty sure it is a Mono problem.

If I use the "mono.exe", "mono-2.0.dll" and "mscorlib.dll" from the Mono 3.0.10 installer. Everything works fine.

If I use the "mono.exe", "libmonoboehm-2.0.dll" and "mscorlib.dll" from the Mono 3.2.3 installer. The print dialog is not shown.


It makes it hard to bisect, since there is no release between 3.0.10 and 3.2.3. So it's a big commit stack to run through.

There are some releases between 3.0.10 and 3.2.3. However, I don't mean bisecting through releases but through each commit. You would need to build mono yourself.
Comment 7 Andres G. Aragoneses 2014-03-31 10:15:58 UTC
Also, probably the biggest change between 3.0.10 and 3.2.3 is the default garbage collector used. So, to rule out the GC as a cause, you would need to test with 3.2.3 using the boehm collector instead of sgen (like 3.0.10's default).
Comment 8 Mikkel Kruse Johnsen 2014-03-31 10:20:24 UTC
As I understand it, windows build has been broken for a while. I'm am unable to compile mono for windows between 3.0.10 and 3.2.3 my self.

There are no windows build between 3.0.10 and 3.2.3 on http://download.mono-project.com/archive/

I have testet with both Boehm and SGen and they both fail.
Comment 9 Mikkel Kruse Johnsen 2014-04-02 03:21:13 UTC
Just testet with Mono 3.4.0 and it has the same bug.

Gtk# print dialog is not shown and the program hangs.

(working with Mono 3.0.10)
Comment 10 Mikkel Kruse Johnsen 2014-04-03 01:53:16 UTC
diff -Nur mono-3.0.10/mono/metadata/threads.c mono-3.4.0/mono/metadata/threads.c

Is a 2500 line patch. So I guess a lot has changed with threads.

Could this be changed back to a Mono problem, since it works fine with mono 3.0.10, I don't see how it can be a Gtk# problem ?
Comment 11 Andres G. Aragoneses 2014-04-03 15:19:50 UTC
Can you obtain a log of all the traces of all the threads when it hangs? See http://stackoverflow.com/questions/2067359/how-do-i-make-a-thread-dump-with-mono for more info.
Comment 12 Andres G. Aragoneses 2014-04-03 15:21:00 UTC
Oh, just realised you are in Windows, not Linux... so I'm not sure if you can kill mono with msysgit?
Comment 13 Mikkel Kruse Johnsen 2014-04-23 07:38:09 UTC
I have changed to Runtime again.

This is not a Gtk# bug.
Comment 14 Mikkel Kruse Johnsen 2014-08-25 07:29:40 UTC
Just tested with Mono 3.6.0 on Windows. Printing still hangs Gtk.

gtk-demo.exe is working, so it is a problem with either Gtk# or Mono. But since it works fine with Mono 3.0.12, I assume it is a Mono problem.
Comment 15 Mikkel Kruse Johnsen 2014-09-10 03:38:23 UTC
Seems to have been resolved with Mono 3.8
