Re: [libvirt] PATCH [0/2]: Deprecate conn, dom, net virterror fields

This is a pair of patches which deprecate the conn, dom and net fields in the virterror structure. Programs which use these fields will get a warning (if compiled under gcc anyway): foo.c:123: warning: 'dom' is deprecated (declared at /usr/include/libvirt/virterror.h:81) The fields themselves are still present and still set, so the ABI isn't changed. Now the patch is quite a lot more involved than you might think for such a simple change. Part of the problem is that we want to allow libvirt itself to modify these fields without generating a warning. Therefore the first part of the patch has to refactor all code within libvirt which includes "libvirt.h" or "virterror.h" (the public headers) so that instead this code just includes "internal.h". "internal.h" already includes the public headers. This allows "internal.h" to undefine the deprecation macro. Of course nothing is quite so simple. We have two "internal.h" files, so I renamed the one in the qemud directory to "qemud.h". I also added something in the HACKING file, stating how *.c files within libvirt should include header files. The second part of the patch actually adds the deprecation to the fields in virterror, and hence is small and simple.
