Bug #2081
Crash while adding self created channels
0%
Description
I've added a channelfile by myself. After writing all infos into the file and restarting tv-headend, the services crashes... I cannot figure out why it crashes. There's no speaking crash message except this one:

The file content:
root@home:/home/hts/.hts/tvheadend# cat channel/1
{
"number": 2,
"dvr_pre_time": 5,
"dvr_pst_time": 5,
"services": [
"5ca224e0a51fab89d79f9e17dc0ce923"
],
"tags": [

]
}
The servicefile exists, too:
root@home:/home/hts/.hts/tvheadend# find . |grep 5ca224e0a51fab89d79f9e17dc0ce923

Updated by Ok, found that the filename has to be a md5sum of the sid? After naming the file in this style the service does not crash anymore...
Perhaps this exception should be better catched?

If you start messing about with teh config files by hand its out of spec and not going to spend much time worrying about it.
Yes TVH could have better validation in many places, but we take the approach of validating things that can (or more correctly are allowed) to be influenced via an external process. A file that's completely malformed due to not being created via TVH would fail that test.
