# RPMS gnome-panel-2.13.2-1.1.i386 evolution-data-server-1.5.2-1.1.i386

Steps to reproduce:
=======================
1) remove any running clock applets
2) from a terminal type ...
   $ ltrace -s256 -f -S -o /tmp/clock-applet.ltrace /usr/libexec/clock-applet
3) add clock applet to panel by right clicking panel and selecting "Add to panel
..."
4) click the clock applet 

Expected results:
=======================
drop down calendar appears showing any evolution VTODO and VEVENTs

Actual results:
=======================
no drop down calendar dialog displays, the applet is still alive and has a
depressed button look to it (as if the calendar did display).  

Using ltrace it appears to hang when writing to a socket ...

4109 SYS_socketcall(1, 0xbfba3c00, 0x94bb4c, 0x8ce57c0, 0x8ce9588)           = 14

4109 SYS_writev(14, 0x8ce55a8, 2, 2, 0x7d2ff4)                               = 230
4109 SYS_futex(0x8ce1914, 0, 1, 0, 1)                                        = -4

Please advise if there are any additional debugging steps you'd like me to perform.

> 4109 SYS_futex(0x8ce1914, 0, 1, 0, 1)

I think that may be some sort of thread lock contention. The first 0 there means
this is doing a FUTEX_WAIT operation and the second 0 means block indefinitely
until the lock is released.  

The -4 means EINTR (it stopped blocking not because the lock was available, but
because it got signal).

Thanks; I'm seeing this as well and am debugging...
Comment 3 Dave Malcolm 2005-12-15 15:40:16 EST
I get the simple part of the symptoms reported in the bug; I'm seeing a possible
problem in position_calendar_popup; looks like it might simply be picking a
bogus y coordinate and the calendar popups up offscreen.

This is with a Top orientation panel, using metacity.

If I mess around with the orientation in Panel properties, I can get the
calendar popup to appear at times, albeit in the wrong location (if I change it
whilst the calendar visibility toggle is in a "depressed" state, then the
calendar popup appears but in the location relating to the previous panel
orientation).

Possibly also a bad window manager interaction; the panel code tries to pick a
good location for the calendar popup window, and calls:
  gtk_window_move (GTK_WINDOW (window), x, y);
  gtk_window_set_gravity (GTK_WINDOW (window), gravity);
then
  gtk_window_present (GTK_WINDOW (window));

Incidentally, I'm correctly seeing my tasks and appointments when I do manage to
make it visible

I can confirm that it's appearing off-screen.  I'm using twm, and the title bar
it gives to the calendar window is partially on-screen, on the lower right.

Don't know if it's useful or not, but running xwininfo against it, on a 1280x960
display, gives this information:
  Absolute upper-left X:  1020
  Absolute upper-left Y:  969

This appears to be working now in rawhide-20051221 which includes

evolution-2.5.3-1.i386.rpm            
evolution-data-server-1.5.3-2.i386.rpm
evolution-devel-2.5.3-1.i386.rpm
evolution-connector-2.5.3-1.i386.rpm
evolution-data-server-devel-1.5.3-2.i386.rpm
evolution-webcal-2.4.1-2.i386.rpm
gnome-panel-2.13.3-2.i386.rpm
Comment 7 Dave Malcolm 2006-01-11 17:51:44 EST
Working for me as well; I'm going to resolve this as fixed in rawhide.  Please
reopen it if symptoms persist.
