subject:"\[Bug 346964\] Re\: menu items selected from screen 1 open on screen 0"

Here is a patch with both the fix and debugging information.

Use this only if the later patch doesn't work.

I don't know if you need libglib or libgio-fam, so install both .debs.

And here is the patch without debugging information.

TRY THIS FIRST.

Again, this is a bug in glib, NOT gnome-panel.

Nope, above doesn't work, this should:

static gboolean
is_env (const char *a,
const char *b)
{
  while (*a == *b)
  {
if (*a == 0 || *b == 0 || *b == '=') /* cover naughty equals usage */
  return FALSE;

a++;
b++;
  }

  if (*a == '=' && *b == 0)
return TRUE;

  return FALSE;

[Bug 346964] Re: menu items selected from screen 1 open on screen 0

Okay, I think I found the problem.

I think this is a bug in the "is_env()" function in glib2.0 file
gdesktopappinfo.c.

I will be providing a patch shortly once I have tested it locally.

Basically what's happening is the environment passed to the spawned
process has 2 "DISPLAY=" lines, one with "DISPLAY=:0.0" and another with
"DISPLAY=:0.1".

The is_env() function as written is CLEARLY wrong.

Untested version of the new fix:

/* '=' is the new '\0'.
 * DO NOT CALL unless at least one string ends with '='
 */
static gboolean
is_env (const char *a,
const char *b)
{
  while (*a == *b)
  {
if (*a == '=' && *b == 0) /* return true if at end of b and a is on =. */
  return TRUE;

if (*a == '=' || *a == 0 || *b == 0) /* otherwise return if at the end of 
either string. */
  return FALSE;

a++;
b++;
  }

  return FALSE;
}

The old version would bomb out with FALSE if *a==0 || *b==0, but the
actual correct TRUE case (shown above) is (*a == '=' and *b == 0).

2009-05-28 Thread yakovlev

Actually, this helps a lot.

What this tells us is that this is actually a bug in glib2.0 function
g_app_info_launch_uris().

The bug occurs when this is launched with a context including a screen
with gdk_screen_make_display_name(screen)=":0.1" but the parent process
has DISPLAY=":0.0"

Here is a snippet of the relevent code sequence in gnome-panel:

...
gdk_app_launch_context_set_screen (context, screen);
gdk_app_launch_context_set_timestamp (context, timestamp);

local_error = NULL;
retval = g_app_info_launch_uris (appinfo, uris,
 (GAppLaunchContext *) context,

2009-05-27 Thread yakovlev

Okay, now for a patched gnome-panel.

For this one, you'll need to install the gnome-panel and libpanel .debs.
To get the old ones, recompile without the patch and reinstall the
.debs.  There also may be a way to force synaptic/apt-get to reinstall
over the current ones, but I'm not sure what it is.

This test again puts data in ~/foo.

It outputs some information on startup, and other information when the
application is launched.

This should tell us whether the bug is in gnome-panel or in the
underlying gnome/GTK libraries.  Right now I'm about 50/50 as to which I
suspect.

Install the debs listed above and then log out and log back in.  (I've
tested on my single display machine, so you should be okay as far as
hosing your system, though this may leak memory.)

Then run an application on screen 1 that shows up on the wrong screen
(screen 0), and send the output.

Thanks!

Interesting...

I need one more thing... it will take a while for me to get a new patch
file ready, if you can do this yourself, that would be great.

Basically, I need to add the following lines to the previous patch so
that I have the value of the "DISPLAY" environment variable.  I think
some other users were using `bash -c executable` to get things working,
which I don't understand why it worked.:

char *fdfoodisplay;
fdfoodisplay = getenv( "DISPLAY" );

fprintf(fdfoo, "DISPLAY Environment Variable is: \"%s\"\n",
fdfoodisplay);

[Bug 346964] Re: menu items selected from screen 1 open on screen 0

2009-05-15 Thread yakovlev

I think you're missing the point.

Add a gnome-panel launcher (temporarily, of course) to screen 1 which
launches the hacked gnome-terminal.  Then use that to make it appear on
the *wrong* screen.  **What I most need the output of is a run where
gnome-terminal shows up on the wrong screen.**

The other cases I would like (for comparison) are a run where gnome-
terminal is launched in the same way from screen 0 and appears on screen
0, and a run where it is launched "correctly" on screen 1 (maybe via
your hack.)

What I'm trying to do is figure out just where the bad terminal info is
coming from, so that I work backwards and attack the problem from there.

In particular, I want to see if the environment that gnome-terminal is
picking up is bad, or if the problem comes from something in the DBUS
code ignoring the environment that is passed to it.

Thanks!

[Bug 346964] Re: menu items selected from screen 1 open on screen 0

Ok I tried to use the patch.  There's one problem...  In order to open
the program on screen 1 I have to use a hack to get it to open onto that
screen.  Once the terminal is opened on the right screen calling the
apps directly through this opens up on the correct terminal.

Also if you set the environment display variable "export DISPLAY=':0.1'"
and call the programs from the command line they all open fine.

So long story short, you can not replicate the problem from the
terminal.  To get the info you're looking for I'd recommend hacking
gnome-panel and output it's info instead.


Thanks for looking into it.

[Bug 346964] Re: menu items selected from screen 1 open on screen 0

I've attached a hacked version of gnome-terminal that dumps some screen
information to a file called "foo" in your home directory when run.

THIS IS NOT a secure version, DO NOT install the resulting hacked .deb.

However, if you compile gnome-terminal with this patch to
src/terminal.c, you should be able to get some debug information.

I need someone experiencing the problem to run the resulting binary from
a terminal on screen 1 and from a panel launcher on screen 1.

Hopefully we'll get different results which we can use to further debug
the problem.

How to use:
Log into your home directory.

sudo apt-get build-dep gnome-terminal
*NOTE: NO SUDO BELOW HERE*
mkdir temp
cd temp
apt-get source gnome-terminal
cd gnome-terminal-2.26.0
cd src
patch terminal.c /path/to/gnome-terminal-fdfoo.patch
cd ..
dpkg-buildpackage -rfakeroot -b

This will build some packages in your temp directory... ignore these.

What you want to do now is run the resulting executable file:

temp/gnome-terminal-2.26.0/src/gnome-terminal

in as many ways as possible from screen 1 (and maybe some from screen
0.)

Then, please post the results (appended to file "~/foo") and where the
terminal appeared here.

Thanks!
