[mythtv] Using QUERY_GETALLPENDING from a SBE

[Guillaume Membré]

hello,

I'm trying to query the MBE from a SBE to get the next upcoming
recording. I looked the way the option --printsched works and I tried
to use Scheduler::FillRecordListFromMaster(). I also modify the method
ProgramList::FromScheduler() to force the query QUERY_GETALLPENDING
even if it is run from a SBE. It returns a good result but my SBE gets
flooded by SCHEDULE_CHANGE messages. I think they comes from the MBE
but I don't understand why such messages are sent.
I also try to use Scheduler::FillRecordList() but I think only the MBE
shoud use it as it query the database and may modify it, so I end up
to forgive this option.

Here is an output of what happens :

and so on until I kill my SBE

My question is : how can I avoid those SCHEDULE_CHANGE messages ?

Any help is greatly appreciated.
