[confirm] RC4 SVN (25965) TvPlugin.TVProgramInfo is still slow (recording screen) (1 Viewer)

Hi!

Programs that are repeated very often like let's say daily 4 times. Are taking up to 3 minutes on my system to show the TvPlugin.TVProgramInfo screen.

Complete logs in Post #3.

Are you talking about this?

0002927: Delays in displaying upcoming programs from EPG - MediaPortal Bugtracker

If so, it is fixed in RC5.

If not, could you please provide a clear description of the problem and full logs?

Mark

Hi elliottmc,

as mentioned in the topic i'm using SVN 25965 which is after the fix - that is why i wanted to point this out again.

Attached you'll find full logs - simply viewing the programinfo recording screen which takes up to 3 minutes.

EDIT:
- the show is running on about 8 channels daily every day - so this seems related to the mass of available alternatives
- but CPU usage on client and server is really low while waiting

How many schedules do you have setup?

The fix there was removing a loop over all schedules which in turn was looping over all schedules again. There was some other similar code to set the recording pins.

If you delete all your schedules does it speed things up?

I've about 21 recordings. How can i safely remove them without loosing them? Is the loop still needed? As far as i can remember gemx introduced some code which flags the programs in epg directly.

Schedules not recordings. You can export/import these

sorry i also meant schedules - will try your suggestions later this evening.

you're right if i delete my 21 schedules it's fast like hell! But i think 21 schedules isn't so much isn't it?

Any idea where to look into code? sadly i don't know how to debug the tvplugin dll

Agreed but when I looked through the code it was pretty messy and involved and I was struggling to figure out what code was needed and what wasn't

IIRC the delay is the multiple calls to IsRecordingProgram in PopulateListViewWithUpcomingEpisodes method in TVProgramInfo.cs. I have a feeling this builds up a list of upcoming epidoes from guide as well as a list of scheduled recordings; it then combines the two lists and itterates over each entry calling IsRecordingProgram. That method then loops over all schedules to build up a list of what is going to be recorded and tries to establish whether the episode it is looking for is in that list. It does this for each episode....

The original loop was to set the IsSeries variable and that called the IsRecordingProgram method for every schedule so actually itterated over every schedule within a loop itterating over every schedule The outer loop was removed but the next part (which is slow as you have seen) is looking far more complicated to fix without a complete rewrite

Mhm but is this still needed? Isn't the IsRecordingProgram now set / flagged in the program database?
