Kodi freezes when Enabling MythTV add-on - fossum_13 - 2018-08-29

While enabling the MythTV plug-in the GUI freezes if the backend isn't available. In the process of creating this bug, the interface came back, so not a bug. Still very annoying, because the user has no idea why it doesn't work. Ideally the GUI should be doing this work in a background process. Is there any way to get this in the road-map?

Steps to reproduce:
  1. From an Ubuntu environment, install Kodi through Software Center (if it matters).
  2. Open Kodi (cause I forgot I needed the plug-in).
  3. Installed kodi-pvr-mythtv through apt (if it matters).
  4. Configured plug-in with IP.
  5. Clicked enable for the plug-in.
  6. GUI freezes for 2-5 minutes, but eventually comes back.

Hi, I will try that today...

RE: Kodi freezes when Enabling MythTV add-on - janbar - 2018-09-01

So , I found the trouble. Seems there is a GUI deadlock when the addon launcher try to notify the user about the connection failure. For now the fix is to remove this dialog.

EDIT: It has been tested with kodi Krypton without issue. Testing with Leia fails now. I fixed the issue with the release 5.8.6.
The fix removes the dialog causing the gui deadlock, and I push queue notification instead. It seems to not cause any lock: to be hardly tested ...

@janbar I've been using 4.17.0 with all of the Kodi 18 alpha builds.  I decided to try beta 1 yesterday and built it with the latest in your master branch (commit 790).  I didn't take any logs, but playback would just freeze after a minute or two.  I had some other kodi related issues with stutter in videos, so I've rolled back to alpha3.  I decided to build pvr.mythtv commit 790 against Kodi 18 alpha 3 and kodi then crashed on startup, which sounds similar to this issue.  I had to reinstall 4.17.0 again.  Do you have a suggestion on what is the latest commit of pvr.mythtv I could try for alpha 3?  Also, what is the numbering system?  Are releases 4.x.y and pre-releases 5.x.y?

It shouldn't work !!! Kodi 18 requires pvr.mythtv addon version 5.x.
The addon version 4.x runs with Krypton only.

Have you more than one pvr.mythtv addon installed with different version ? ... and kodi uses the bad one from system libs or user data.

If you want to try the lastest effortlessly then you should install the nightly build of kodi Leia18. Also cleanup any pvr.mythtv addon from user data: $HOME/.kodi/addons/ .

If you want to build yourself the addon to work with kodi 18 from alpha3 or newer, you have to pull the latest commit from the branch master of my repository (commit 790). Also you'll need kodi sources to achieve the build and you have to cleanup any previous addon installation (4.17 or 5.x somewhere on the system ?) from your system or the kodi user data folder.

In my opinion when you want build the addon yourself then you should also build kodi itself to be sure not installing an other pvr.mythtv addon that is supplied with official kodi installation. Or you have to cleanup any pvr.mythtv addon installed with kodi installation. Then you will install your build of the addon in the kodi user data folder: $HOME/.kodi/addons/ .

@janbar well maybe that will explain some things... 4.17 actually seems pretty stable aside from these playback issues... I forgot to mention that I am using an Arch based linux that does not have Kodi 18 in the repository and so I don't have much of a choice besides building the packages from source.  I presume that the user data you are referring to is in $HOME/.kodi/userdata/addon_data/pvr.mythtv?

RE: Kodi freezes when Enabling MythTV add-on - knappster - 2018-09-02

I stand corrected... The PKGBUILD file says that it is 4.17.0, however, in reality the one which is working with some performance issues is 5.8.1 looking at the kodi addon information.  Kodi 5.8.6 crashes alpha 3 when it is enabled.  The source for alpha 3 was downloaded when compiling 5.8.6.  When I built it for beta 1, the installation file was about 50kB larger.  I'm trying to compile each of the milestone pre-releases with the expectation that things will improve each time.  I think I will give the beta 1 a skip though and try again with beta 2.  It sounds like you are working on keeping it compatible with dailies and I don't want to waste your time with older pre-releases.

@knappster , the mannually installed addon are stored in folder $HOME/.kodi/addons/.
The binary size should greater than 500K, else it misses probably lot of thing that could cause a crash.
You could try to compile the addon for kodi 18 from my branch "devel" which doesn't need kodi sources.

RE: Kodi freezes when Enabling MythTV add-on - knappster - 2018-09-03

@janbar For alpha3 the installation binary for 5.8.1 was 794k and the installation binary for 5.8.6 is 747k
For beta1 the installation binary for 5.8.6 is 798k.

Maybe something went wrong with the compilation of 5.8.6 in alpha3.

BTW, my settings.xml file is in this folder:
$HOME/.kodi/userdata/addon_data/pvr.mythtv

I feel like I am hijacking this thread at this point.  Should I start a new one?
