Subject: fvwm2: Race condition in fvwm2 icon box

Date: Wed, 23 Jul 1997 01:36:42 -0400 (EDT)

Package: fvwm2
Version: 2.0.45-BETA-4

When I start X, my init files start up several programs.  Most of these are
things like xclock, xload, etc.  But one of them is an application that
throws up a couple of windows, one of which is iconified.

The icon for the iconified window doesn't always appear in the icon box.
As far as I can tell, there is a race condition: if the icon box is
configured before the icon is created, then the icon goes in the box.
Otherwise, the icon goes in the upper-left hand corner of the screen.

When the icon is misplaced, if I kill the program and restart it, the icon
is properly placed.  Alternatively, if the icon is properly placed, and I
leave the program running and restart fvwm, the icon is misplaced when fvwm
restarts.

The likelihood of the icon being properly placed is very high on my fast
computer, and quite low on my slow one.

All of this information adds up to a race condition in my mind.

IMO, the icon should go in the box regardless of when it is created.

Thanks for your bug report.  I'm sorry for the delay in getting back
to you, but I've been on holiday recently.

Which sort of icon box are you using?   The standard one defined by
IconBox, or one of FvwmIconMan or FvwmIconBox modules?

Austin

If you want to be sure about what is done earlier: IconBox
configuration or you program execution, you *must* put the execution
in InitFunction. If it is done no problem occur.
