I think MythTV has always been welcoming of code contributions however I
think the best method to do so is:
Create the PR at github: https://github.com/MythTV/mythtv/pulls
Create the corresponding ticket: https://code.mythtv.org/trac

This is largely what is outlined at: https://github.com/MythTV/mythtv
Sample: https://github.com/MythTV/mythtv/pull/121

Note it does sometimes take awhile, but github at least makes sure it can
patch cleanly into master.

> https://github.com/warpme/minimyth2/blob/master/script/
> myth-master/mythtv/files/0324-disable-caches-pruning.patch
> Patch allows to disable cache pruning by setting UIDiskCacheDays to -1.
> Why useful:
> If frontend is used as appliance with sleep/resume regime with mode where
> mythfrontend process is exited at sleep and started at appliance resume -
> cache pruning can considerable increase mythfrontend start time (on my ION2
> it is 11->19..21sec).
> Sure - this we can overcome by moving cache pruning to separate thread
> (which is also good idea IMHO)
> But I have another argument to turn-off pruning some cases:
> lets see 2 cases:
> a\ no pruning:
> (-)bigger disk usage
> (+)no issue with lagging some images on UI (no cache)
> (+)quick, predictable start of frontend
> b\pruning
> (+)space on hdd saved
> (-)noticeable UE impact when playing with UI
> (-)mythfrontend startup sometimes so longer(*) than user thinks it hanged
> For me in mm2 b\ wins clearly.
> Patch allows to user to decide a\ or b\
> (*) I have appliances where mythfrontend wasn’t restarted by weeks. Any
> restart triggers long (10-20sec) of cache pruning.
