#11475: HDHomeRun recorder repeatedly setting filter tracking ticket
-------------------------------------------------+-------------------------
Reporter: Gary Buhrmaster | Owner: danielk
<gary.buhrmaster@…> | Status: new
Type: Bug Report - General | Milestone: unknown
Priority: minor | Version: 0.26-fixes
Component: MythTV - DVB | Keywords: hdhomerun
Severity: medium |
Ticket locked: 0 |
-------------------------------------------------+-------------------------
After the reports on list, irc, and the SD forums indicated that there was
an issue with the MythTV HDHomeRun recorder repeatedly issuing set filter,
I have performed a git bisect of MythTV, and the result is that the first
commit that is causing the problem appears to be
9b22460f53bf6313516f33987e4260897c6076a3 which is "Merge of various
recorder changes from mythtv-rec2". This seems to generate new filter
updates hundreds (or more) times per second. The second commit
0542a100237dd26bcbc60212c443f4619586f15b "Refs #10414. Lower HDHomeRun
recorder CPU usage a tiny bit more." sets a timer to only update the
filters about 10 times per second (the currently observed rate). For
testing purposes, I have created a patch against fixes/0.26 which updates
the filter on the hdhomerun only when the code indicates that the filter
list has been changed (attached). It should not be considered complete,
but simply as a proof of concept. In particular, I have not looked at EIT
filter changes, nor other recorders.
Kenni Lund suggested that I submit this ticket.
