[Libvir] python/libvir.c returning wrong value on error?
by Cole Robinson 07 Feb '08

07 Feb '08

Hi all, Looking at python/libvir.c, all the custom functions return VIR_PY_NONE on error. This unfortunately doesn't map well to some of the generated python bindings which expect an error val of -1. So if these commands fail, no exception will be thrown at the python level. (Ex. virDomainGetAutostart, virDomainGetVcpus and their python equiv.) I'm wondering where the fix should be: in python/libvir.c, changing these error return values, or in the generator somewhere? Thanks, Cole

[Libvir] Pthreads error in windows compilation
by Gabriel Kaufmann 07 Feb '08

07 Feb '08

Hi, I received the error In file included from libvirt.c:32: internal.h: At top level: internal.h:177: error: expected specifier-qualifier-list before 'pthread_mutex_t' In order to fix this problem, I installed the 'pthreads' package on my MinGW. Then added include pthread.h in src/internal.h Is this the right action?

I have a slight preference to remove -Winline, but either way is ok.

Hi, Ignore this mail and look at the two following ... I can't figure out how to make "quilt mail" send one of these intro mails, even when sending a single patch :-) Cheers, Mark. --
