I don't know. Does it? It almost seems so when looking at the Nautilus
source, but I haven't read anything about that in the documentation.
Afterall, its purpose is to allow for transfers running asynchronously
to the main thread, so why should it call its signal handlers from
anywhere but its own thread of execution?
gnome-vfs sources, file gnome-vfs-job.c, function job_notify. It adds
idle handler, that calls the callback, to the main loop. It doesn't call
the callback function by itself in its own thread.
I don't know how it happens that your function gets called from
another thread.
I thought this is how gnome-vfs' async functions work. You connect
your signal handlers, start the transfer(), it kicks off its own
thread and sends updates periodically to report progress. In this case
I see no reason why my signal handler would not be called from the
thread which is running the transfer (and which is most certainly not
the main thread).
You can use gdb to set up a break point in your function and see how
execution flow gets to your function and in which thread's context.
wbr, Dmitry.
