When I was looking at the code to figure out a bug I found (fix: https://github.com/MythTV/mythtv/pull/385
(changes in 385 now);
noticed the code in mythcontext was messy and not very readable.
My goal is to make the code more readable (some work, subject to changes
and rebasing, is on my fork https://github.com/ulmus-scott/mythtv
Much work remains, e.g. merging the anemic MythContextSlotHandler into
MythContextPrivate, separating the settings caches into their own
classes, some old cache format code to remove, some hacks to test.
I was originally only looking at MythContext, but I got distracted by
the unnecessary shim duplication of MythDB’s methods in
MythCoreContext. I was also thinking of making the MythDB instance a
global variable, but thinking on it some more, it would probably be
better to make it a member of MythCoreContext (still exposing it via the
global GetMythDB() ), since trying to access it uninitialized doesn’t
make any sense.
Communicating between MythCoreContext and MythContext via QObjects and
QEvents, seems, at the very least, hack-y, if not breaking
encapsulation. I’m thinking of renaming MythContext to MythGUIContext,
as seems to have been the intent, and make it a subclass of
MythCoreContext, overriding the CLI superclass methods with the subclass
Does MythCoreContext need to be a QObject? The TVPlayback signals
(without having looked at them) seem out of scope for MythCoreContext
(frontend only? And thus GUI only?).
Beyond current scope of work:
cleanup in MythMainWindow (similarly quasi-global as MythDB) (seems to
also be MythCoreContext’s GUIObject)
Improve logging with __FILE__, __LINE__, and __func__. Readability:
define masks with bit shifting. Add a mask for fonts to enable
disabling output (debug produces lots of extraneous font messages).
