#3093: program guide with no input connections defined --> segfault
---------------------------------+------------------------------------------
Reporter: jharvell [at] dogpad | Owner: stuarta
Type: defect | Status: new
Priority: minor | Milestone: 0.21
Component: mythtv | Version: 0.20
Severity: medium | Resolution:
---------------------------------+------------------------------------------
Comment (by jharvell [at] dogpad):
Are you sure my expectation is wrong? It is based on documentation from
www.mythtv.org (see below). The reason I deleted all my input connections
is because they are not physically connected to anything yet. I am
staging the machine. I had to define the input connections first so I
could get the channels and programming. Then I deleted the input
connections to reflect the fact that there is no video source connected to
the inputs. This prevents the scheduler from trying to use the input
connection. I had to use this before with a previous Myth box when I
temporarily had to disconnect one of the video sources from an input. The
scheduler seems to work fine when you delete one of the inputs. It
doesn't try to record from that input. The only thing I've observed to
have problems is the program guide.
Also, if you are going to fix the segfault, then I think you should also
change the wording of the error message on the basis that it's at best
misleading and arguably incorrect. In fact, channels are defined in the
database. Your argument that they are "orpahned" doesn't really make
sense. They are not weak entities and have no existence dependeny on
input connections. The fact that the EPG tries to do a natural join
involving the input connections and comes up with nothing does not mean
the channels are orphaned. If you assert that the EPG is not designed to
work without input connections, that's fine. But the error message is in
fact wrong.
Now, on to the actual expected behavior. Is there any documentation other
than the web page where I could find the expected behavior? If not, then
either the EPG needs to be fixed or the web page needs to be updated. My
expectation is reasonable. If it is wrong as you say, then how can I make
a feature request? It seems reasonable to be able to look at the program
guide and schedule programming while no video sources are connected to the
inputs. In fact, I shouldn't even have to have a capture card defined to
do that. I think the things that need to exist to look at the programming
guide and schedule recordings are the video sources, the channels, and of
course the programs.

NOTE: Don't add a video source to a hardware input if you don't actually
have anything connected there. For example, adding "Cable" to the Tuner
and to the Composite inputs without having something connected to
Composite will lead to blank recordings.
