And this is one where the fears of removing the brackets sets in -
inline MACROs that do not have a 'do { ... } while(0)' definition....
I thought perhaps it'd be vbox and the funky macros there, but if you
look at the #define for EDIT_NOT_CHANGED it differs within the various
virsh-*.c files.
For example, in virsh-domain.c there's:
#define EDIT_NOT_CHANGED \
vshPrint(ctl, _("Saved image %s XML configuration " \
"not changed.\n"), file); \
ret = true; goto edit_cleanup;
So, in effect the second line will always be executed as I'm reading things.
there's also :
#define EDIT_NOT_CHANGED \
vshPrint(ctl, "%s", _("Metadata not changed")); \
ret = true; \
goto edit_cleanup;
and
#define EDIT_NOT_CHANGED \
vshPrint(ctl, _("Domain %s XML configuration not changed.\n"), \
virDomainGetName(dom)); \
ret = true; goto edit_cleanup;
I think modifying the macros to have the do {...} while(0); syntax will
do the trick.
