Python script to be notified of channel lineup changes

bnhf · February 10, 2024, 3:05pm

Looks promising, but I did need to make one change to the code (and related comment) at lines 331 and 335:

def create_data_subdirectory(ip_address, port_number):
    '''
    Create a directory with the path as:
    current directory + "_<ip_address>-<port_number>_data" at the end
    '''
    global Data_Subdirectory_Path

    end_of_path = f'{ip_address}-{port_number}_data'
    data_subdirectory_path = os.path.join(os.getcwd(), end_of_path)

    if not os.path.exists(data_subdirectory_path):
        os.mkdir(data_subdirectory_path)
        
    Data_Subdirectory_Path = data_subdirectory_path

"_" changed to "-" between {ip_address} and {port_number}

On first run the data files ended up under /root again, but this time I cleverly changed the directory to /config before running the script. Don't know why I didn't think of that before. It's good to have the data files in a subdirectory though.

Thanks for the feedback and the code change. I'll make the correction.

I'm curious: when you refer to "./” in OliveTin, what is the actual full path for this current directory?

bnhf · February 10, 2024, 4:10pm

/config is the usual working directory for most scripts, as that's the one that's bound to the host. All the scripts are there, as well as logs and other data-files -- some of which are in sub-directories.

I'm not landing in that directory on container start though, and I use the full path for many/most things, since a container has a completely predictable file system. It'd probably make sense to just change to /config at container start, as opposed to doing it as needed for a given script.

mjitkop · February 10, 2024, 4:53pm

OK so you don't think I need to make any more changes in my script with regard to the directory names?
I think this is what I'm understanding but please confirm.

bnhf · February 10, 2024, 5:07pm

Yes -- all good! Just the "-" change referenced above.

New OliveTin-for-Channels pushed incorporating the latest 3.x version of this excellent script:

chDVRuser · February 10, 2024, 7:55pm

Thanks much for the new improved script!
Especially the persistent reference files that keep track of channels between runs/restarts.

Have a question regarding this

I don't see the duplicate channels called out, for instance in my Pluto source. Are they supposed to appear? I'm not doing text/email notifications as that's overkill for me. Just looking in the log file.

Checking every 30 minutes atm for "stress testing". I'm not doing PERSISTENT_LOGS though, so I'm not sure what my first run looked like anymore. @chDVRuser maybe shorten your interval for testing purposes, and see if the next run shows the dups?

chDVRuser · February 10, 2024, 8:54pm

Nope. Changed it to a 5 minute interval

mjitkop · February 10, 2024, 8:59pm

@chDVRuser in the case where a new source is found, the script doesn't check the lineup itself, it just reports the new source and the number of channels

That's one thing I didn't think of.

Duplicated channels get reported only if a lineup has changed.

I can add it.

chDVRuser · February 10, 2024, 9:12pm

Ahh, thanks for the explanation.
No need to add it as I just wanted to make sure the log file contained the same detailed message that would be emailed. I'm over-notified of too many things and don't need text msgs/email that channel lineups have changed!

Text msg says check your email
Email says check a wesbite
Website says Check your secure messages
I had already logged in the Website and read the Secure message

mjitkop · February 10, 2024, 9:22pm

Yes. Unless I made a mistake in the code, the contents of the log file and the email should be the same.

Is this from OliveTin? That's not from my script.

chDVRuser · February 10, 2024, 9:23pm

No. Just in general. Over Notified.

mjitkop · February 10, 2024, 9:24pm

I see. Got it.

mjitkop · February 13, 2024, 7:43pm

@bnhf and @chDVRuser
I got a change in my Pluto TV source today. I'm expecting that you should get it too.
I'm curious to get your feedback about the reported changes that you will see.

chDVRuser · February 14, 2024, 6:12am

Looking good.
Picked up changes on two of my servers.

mjitkop · February 14, 2024, 2:06pm

Great, @chDVRuser!

I'm curious about Big Ten Network Alternate on Fubo. Is that right that it appears 3 times on 3 consecutive channel numbers? Are they different versions?

Also, it looks like the two examples that you posted came from the same server machine at 192.168.1.3.
How can it be that Fubo starts at 9000 and Pluto at 9001? That's not a bug in my script?
I can see that they are from two different dockers so maybe they are used by different Channels DVR servers?

I have everything on one machine so it was strange at first for me to wrap my head around your configuration. I'm guessing you have something like this:

joagomez · February 14, 2024, 2:13pm

The Big Ten alternates are different feeds, but typically only show different games during football season.
