[telegram] Telegram Binding initial contribution #5677

ZzetT · 2019-06-02T16:48:49Z

This binding shall work as a replacement for the old OH1 Telegram Actions.
It supports not only sending messages, but also receiving them. The base for the implementation is the TelegramBot library.

User Belgadon (Jens) initially started the work on that binding which still used the old OH1 telegram actions for sending messages. I removed this dependency by using the new OH2 actions and "tried" to migrate it to the new build environement.

The development of that binding was discussed in that thread.

Although I still didn't completly manage to get it running with the latest build environemnt, I was told in the forum to create a PR anyway.
The problems that I still have are either OSGI errors when I click "Resolve" in the bnd demo app or
when I add:

  <properties>
    <bnd.importpackage>org.telegram.telegrambots.*;resolution:="optional"</bnd.importpackage>
  </properties>

then I get ClassNotFoundExceptions at runtime after adding a new Telegram thing.
One more thing to note here, IMHO it should not be necessary to also add a dependency to "telegrambots-meta" in the pom.xml (only telegrambots should be required), but if I remove that I get an error that this is missing.

Please note that the binding is using an apache client instead of a jetty client, but this issue was discussed already and agreed by @davidgraeff .

So, before continuing the work on more features, we need the approval that the library can be integrated into the OH2 environment and what needs to be configured to get it running again. Then, I hope that we can add a few more features in separate PRs for this binding.
Especially two things are currently missing compared to the old Telegram actions:

sending photos located on a webserver that requires username/password
support of html markup (should be easy to realize)

Currently, a beta version of that binding was released to several testers in the forum which however was only based on the old build environement.

The problem with the bnd resolver may be that the libraries are not OSGi-libraries and require wrapping. I think that BND cannot do that on the fly. #5503 will help with this. This will work in KARAF because wrapping (as requested on the feature.xml) is available.

Adding optional to bnd.importpackage is wrong. You need these classes, they are not optional but required. As a workaround you can add the libraries to the /lib directory. But please do not commit these files.

The library is MIT licensed, I do not see any problem in using it. I didn't check why you use apache http client, can you add a note to this PR? It's easier to find in case someone wants to look it up.

I'm not using the apache http client, but the Telegram library does. I tried to rewrite it, but there were a lot of changes necessary and it would be a big effort to keep it up to date with the original library.

J-N-K · 2019-06-02T21:21:35Z

Ok with me as well. Don‘t rewrite external libs.

Adding optional to bnd.importpackage is wrong. You need these classes, they are not optional but required. As a workaround you can add the libraries to the /lib directory. But please do not commit these files.

But then do I need this bnd importpackage at all? I found only very few bindings that have this. And some others also use an external library but don't have this bnd statement.

Sorry, I accidentally removed it now. Shall I just remove the optional attribute?

J-N-K · 2019-06-03T19:21:26Z

This is only for very special cases with embedded libraries. You don‘t need it.

J-N-K · 2019-06-06T17:25:42Z

Is there anything missing from me here?

@J-N-K There is still a "changes requested" review from you here - so yes, if you are satisfied, you should change it to an approval.

J-N-K · 2019-06-08T16:06:47Z

Mhm. Is there any better way to remove "requests changes"? I only looked at the infrastructure part, not at the code.

kaikreuzer · 2019-06-08T16:09:15Z

There is usually also a "dismiss review" button as an option.

Travis tests were successful

Hey @ZzetT,
we found no major flaws with your code. Still you might want to look at this logfile, as we usually suggest some optional improvements.

Why is lastMessageDate a String channel ?

- converted lastMessageDate channel type from String to DateItem - exceptions are now reported to the logger as a warning - in case of a 401 error during getUpdates the thing will go offline because it usually means that the thing configuration (botToken) is wrong - fixed mixed tabs and spaces Signed-off-by: Alexander Krasnogolowy <alexkrasno@hotmail.com>

Thanks for the hint, I changed that now.

From my side I would be ready to merge it to the master unless you guys want to have another look. Since the last review a few things have changed (library replacement).

LGTM; @J-N-K You approved some time ago. If you're ok we can merge this binding.
