If you remember I flagged this on 24.11.2011 with a private mail. After 
the upgrading to GNOME 3.2, not only the gtk3 build was unstable but 
also the old gtk2 builds were unstable...

Since then I am using this target

C:\cygwin-2\bin\run.exe bash -l -c 'GSETTINGS_BACKEND=memory emacs 
-display 127.0.0.1:0.0 2>/dev/null &'

to start Emacs from a link on desktop, and it works both with gtk2 and 
with gtk3 builds.

Notice, I do not use Cygwin service (dbus,... etc.)


Any way I will try to follow your recipe to reproduce the problem, but I 
am sure it is still there..

No, it isn't!

I have run Emacs for more than 14 hours and I haven't see any problem. I 
have done that strictly following your recipe...

Ciao,
Angelo.

Hi Angelo,

That's great news.  Thank you very much for testing.  Now I just have to 
figure out why it doesn't work on my system.  Would you mind sending me 
your cygcheck output off-list so I can see how my setup differs from 
yours?  I wonder if I need some GNOME-related package.  Or it could be 
BLODA.  What anti-virus software do you use (if any)?

Thanks.

Ken

Microsoft Security Essential (MSE)... I would be glad if someone could 
teach me how do not use an AV on Windows... ;-)

I am afraid, I haven't a Windows 7 box :-(

I can confirm that it seems to work fine on Windows XP.  But I have two 
Windows 7 computers on which it still consistently fails.  I'm searching 
for BLODA, but in the meantime, it would be helpful if someone else 
could test it on Windows 7.  I'd like to know if it's a general problem 
on Windows 7 or something specific to my systems.  The recipe is in

Thanks.

Ken

Re: Problems with emacs built with gsettings support

[Ken Brown]

I haven't made in progress in trying to debug this problem.  I think I 
will probably have to build the next release of emacs without GSettings 
support.  (This is a shame, but it's not a regression; emacs has never 
had the possibility of supporting GSettings prior to emacs-24.)  If 
there are any emacs users out there who care about this, read on.

First, here's a summary of what I know.  Everything I say is independent 
of whether I build emacs with gtk2 or gtk3.

* If emacs is built with GSettings support, it seems to work fine on 
Windows XP.

* It also works fine on my 64-bit Windows 7 systems if I

   export GSETTINGS_BACKEND=memory

* It fails on my Windows 7 systems otherwise.  The failure consists of 
emacs crashing with a segmentation fault shortly after it starts.  This 
could happen after a few minutes or a few hours, but it always happens.

* I haven't found any indication that this is a BLODA problem, but I 
can't rule it out either.

It would be very helpful if other people could try it on Windows 7. 
Here are the steps for testing, which are simpler than what I posted 
earlier in the thread:

1. Install my test build of emacs-X11-24.0.95-7 by running

   setup.exe -K http://sanibeltranquility.com/cygwin/kbrown.gpg

and adding http://sanibeltranquility.com/cygwin to the list of mirrors. 
  This was built with gtk3, so you'll have to let setup install a bunch 
of dependencies unless you already have libgtk3_0 installed.

2. Start the X server using the Start Menu shortcut, with no ~/.startxwinrc.

3. In the resulting xterm window:

eval `dbus-launch --sh-syntax`
emacs -Q &

4. Wait a few hours, if necessary, to see if emacs crashes.  You can use 
it or just leave it alone (but don't use it for anything important).

5. Send a note to the list reporting success or failure, with details 
about your system.

6. If it fails, you can rerun setup.exe to restore your previous version 
of emacs.  Or, if you'd like, you can install my build of 
emacs-X11-24.0.95-6, which was built without GSettings support.

Thanks in advance to anyone who is willing to test.

Ken
