I disagree. The definition of the VIR_ONCE_GLOBAL_INIT macro uses virErrorPtr, which means if we don't include virerror.h here, _every_ .c file that uses one-shot initialization would then have to pull in virerror.h. It turns out that all existing clients already do, or we would have hit a compilation error sooner; thus this patch is really only mandatory for the new client later in this series - but that commit has already been nack'd on design grounds. Still, requiring a client .c file to do extra includes just to use the macro makes it harder than necessary, so I'm still in favor of making virthread.h self-contained. ACK, after updating the commit message to explain why. I've pushed 1-3 in this series. Like Dan, I agree that the remainder of the series needs a step back to figure out what the real design goal is, before doing any more refactoring. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
