Re: [libvirt] PATCH: Always log source location if available.

Currently, even though all the logging functions get given the source function and line number, it is just discarded unless priority == DEBUG. As an example, run virsh with logging enabled, and a bogus URI LIBVIRT_DEBUG=1 LIBVIRT_LOG_OUTPUTS=1:stderr virsh -c foo://bar 13:12:06.252: debug : do_open:993 : trying driver 4 (remote) ... 13:12:06.252: debug : do_open:999 : driver 4 remote returned DECLINED 13:12:06.252: error : could not connect to foo://bar 13:12:06.252: debug : virUnrefConnect:232 : unref connection 0x99617b0 1 13:12:06.252: debug : virReleaseConnect:191 : release connection 0x99617b0 Notice how it doesn't tell the user where the log message with 'error' priority came from. The same happens for info & warn levels. With the following patch applied, we always report function if it was passed into virLogMessage() 13:15:00.456: debug : do_open:993 : trying driver 4 (remote) ... 13:15:00.456: debug : do_open:999 : driver 4 remote returned DECLINED 13:15:00.456: error : virLibConnError:390 : could not connect to foo://bar 13:15:00.456: debug : virUnrefConnect:232 : unref connection 0x8dd87b0 1 13:15:00.456: debug : virReleaseConnect:191 : release connection 0x8dd87b0 So, we now see that the error came from virLibConnError at line 390
