Re: [mosquitto-dev] Auth plugin v3 interface seems to be incomplete

[Martin Assarsson <martin.assarsson@xxxxxxxxxx>]

@Tatsuzo

At the moment I still use 1.4.X but plan to use 1.5.X as soon as I see fit.

1. Yes, auth_plugin_v3 concerns only 1.5 and I'm not keen on mixing versions even if it's said to be backwards compatible.

2. Yes, all old variables are still present.

3. The variables posted to my function is only containing null and scanning the code makes it quite obvious.

4. Take a look in ./src/mosquitto_plugin.h from source code. History is available in git.

5. Backwards compatibility should be in place (don't know where I read it though). As said before, I'm not keen on mixing this though.

@Wiebe

Thanks!

I'll take a look at those issues if they affect me in a bad way.

Sorry, I expect (1)(2)(3) are yes, but (4) is no.

I'd like add one.
(5) Current external plugins can operate as it is? They can use
pugin_v2 interface without changing anything?

Assume (2) is no and (5) is yes, I guess mosquitto itself has no
degradation, although pulgin_v3 has degradation from pulgin_v2.
