Exception handler problem in sender

[mariusl]

Hi
I found this error after I uploaded a photo with sender.send_photo.

This is #33 again. It just needs a dummy handler.

[mariusl]

The problem for me is not so much the logging but the exception not handled. I actually get a problem with no_response from Telegram. The message goes through but there is an exception I can only assume is no_response. I commented all the "raise" statements out and made the timeout on the function 1 second. I get all my messages and photos through but the code is broken or missing a specific handler.

[mariusl]

I put the logger stuff in and now have a lot more information reported. Maybe this will help. It does look like no_response from Telegram. I still have the "raise" commented out in the sender.

I am not currently have a runnable telegram CLI configured, and didn't work on this for half an year. So I have no direct clue what's going on.

Can you please try what happens if you enter the sent command

 [disable_preview] send_photo Roaming_Camera './/5897f668-19bc-499f-b422-53e00b41c7fe.jpg' 'Taken at - Saturday 17 October 2015 09:14:50AM'

manually in the cli (with json enabled)?

[luckydonald]

Next step we could test:
What happens if you run that code via the socket?
Use some tool like netcat with the specified port (e.g. 4458) .

$ nc localhost 4458

Then see if that command works, and if you get a response.
Also, how long does it takes?

[mariusl]

I did tyhe test from within cli and it was immediate. The response is included in the code below. I tried the netcat test but cannot get it to work. Also see below. I dont know netcall at all so I can't say that I did it right.

Netcat result

pi@rpi2b /usr/local/src/tg $ nc localhost 4458 send_photo Roamin_Camera /home/pi/development/pi-home-surveillance/dec6dd43-b707-48fb-94f3-585b60a7ca43.jpg 
nc: getaddrinfo: Servname not supported for ai_socktype

[luckydonald]

sorry, I forgot to mention to start the additonal cli parameters listening to the port, and netcat was unclear.

 bin/telegram-cli -k tg-server.pub -W --json -P 4458

Please retry both.
Netcat works by first connecting to it

$ nc localhost 4458 [enter]

and then typing your commands as you would in the CLI

[mariusl]

Ok I got netcat going. I opened telegram as you asked with no problem and I sent messages as below. All with no problem and no delay.

This what I done:-
pi@rpi2b /usr/local/src/tg $ nc localhost 4485
send_photo Roaming_Camera /home/pi/development/pi-home-surveillance/dec6dd43-b707-48fb-94f3-585b60a7ca43.jpg

ANSWER 0

Don't see anything strange unless you did not exdpect a 0 in the answer

[luckydonald]

ANSWER 0 means empty answer. It should return something like {"status": "success"} instead...
You are sure --json is enabled?

[mariusl]

This is how I called telegram and the output from that.

pi@rpi2b /usr/local/src/tg $ bin/telegram-cli -k tg-server.pub -W --json -P 4485

[luckydonald]

If you get a message or some other event, is that json format?

[mariusl]

My application only makes use of sender. I dont read anything back at this time so I cant answer. I can try something if you want to make a suggestion on how to do that.

[luckydonald]

When your CLI recieves a message, can you post that output?

(sorry for the delay)

[luckydonald]

This should be the same as #50 and should be resolved by commit f745d92
