Hi, When I register a callback for events with this function call: eh = guestfs_set_event_callback(g, message_callback, GUESTFS_EVENT_ALL, 0, dev); Shouldnt it capture and redirect messages like this to message_callback(): "libguestfs: error: lstat: /.Trash: No such file or directory" I still get them in stderr .. Thanks, Or

[These two patches are for discussion only] Allow FUSE support to be used directly through the API. This is the second commit. In order to make this usable from guestfish, we have to also bind the events API in guestfish. This is the first commit. Rich.

v4: - Lots more analysis of the /init script and other parts. - Display a list of the longest to shortest activities. - Rebase on top of current head. Rich.

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

The safe_malloc (etc) functions call g->abort_fn on failure. That's not appropriate for language bindings, and we never intended that these internal functions be used from language bindings, that was just a historical accident. This patch series removes any external use of the safe_* functions. Rich.

This set of patches fixes virt-rescue rather cleanly. In particular the problems with handling ^C are completely fixed. Work still to be done before this can go upstream: - Shutdown doesn't work properly if you exit the shell. At the moment to exit you must do 'reboot -f'. Future improvements: - An escape sequence and escape commands that could be handled by virt-rescue,

This fixes the main issues in virt-rescue and is usable. There are some enhancements which could be made (in follow up work): - An escape sequence and escape commands that could be handled by virt-rescue, eg. to shut down the appliance, mount or unmount filesystems. - `virt-rescue -i' could be implemented cleanly by performing the right API calls before handing control to the

This patch isn't ready to go upstream. In fact, I think we might do a quick 1.30 release soon, and save this patch, and also the extensive changes proposed for the test suite[1], to after 1.30. Currently it is not safe to use the same handle from multiple threads, unless you implement your own mutexes. See: http://libguestfs.org/guestfs.3.html#multiple-handles-and-multiple-threads These
