Debian libguestfs packages updated

by Guido Günther

Hi, I finally updated the Debian libguestfs packages: http://honk.sigxcpu.org/con/Libguestfs__Virtual_Machine_Image_Swiss_Army_... Sine we can't run the fuse tests easily in a chroot (since we might be unable to load the module) I'm using the attached patch to skip the tests if /dev/fuse doesn't exist. This probably isn't clean enough to go upstream though. The other patch adjusts the test output of rhbz557655. xstrtol seems to be behaving differently here. I didn't investigate why yet. As a last point: is there a simple way to disable the appliance build altogether? I'd like to ship the Debian package without it so we stay out of the security update trouble and provide them via http. Cheers and thanks for that great tool, -- Guido

[PATCH] Non-working support for GObject Introspection.

by Richard W.M. Jones

Read the README file at the top of this patch first. Problems I see with GObject Introspection: (1) Requires that your code uses GObject; obvious in hindsight given the name. In this case, it seems that we'd have to "register" the guestfs_h structure with GObject (whatever that means). (2) Cannot convert C error codes into exceptions automatically. So all your high level code has to check return values -- ugh. (3) Poor type system (although at least it does have a concept of non-nullable types). For example, you cannot express 31 bit ints, or range types, dependent types, constructed types, etc etc etc. So I think it's OK if your code depends on glib, but for general C interfaces I cannot see this catching on at the moment.
