long polling issues

[kolyande]

Hello!

While using BoostHttpOnlySslClient when timeout much greater than 10 seconds is set for TgLongPoll (50 sec, 100 sec) it leads to std::exception throwing (from here https://github.com/reo7sp/tgbot-cpp/blob/master/src/net/BoostHttpOnlySslClient.cpp#L74) in few seconds after TgLongPoll::start() method call.
What is the reason of that - am I doing something wrong?

And one more - in TgLongPoll::start() method Api::getUpdates() is called twice (here https://github.com/reo7sp/tgbot-cpp/blob/master/src/net/TgLongPoll.cpp#L25 and here https://github.com/reo7sp/tgbot-cpp/blob/master/src/net/TgLongPoll.cpp#L36) both times with the same predefined timeout value, so result is that real long polling period is twice bigger than expected. Or this is how it should work?

Thanks.

Hi!

Thanks for your message.

1. No, that's not supposed to happen. The exception is thrown if the timeout is > 20 seconds. This is because the read timeout in BoostHttpOnlySslClient is hard coded to 20 instead of the value of TgLongPoll::_timeout. The same is true for the CurlHttpClient, where the CURLOPT_TIMEOUT is set to 25 instead of TgLongPoll::_timeout. Currently, I don't have time to fix this. You can temporarily change these two values manually. I'll commit a fix asap if it's not already done by someone else in the meantime.

2. No, this is also not correct. I can't fix this quickly, due to the current structure of TgLongPoll::start(). You can do it quick and dirty if you set _timeout = _timeout / 2.

I'll keep you updated.
