move IXR XML RPC to composer dependency #1970

[splitbrain]

This is a monky patched version of kissyfrot/php-ixr until my PR has
been accepted upstream.

Plugins using the XML RPC client may need adjustments.

Plugins using the XML RPC client may need adjustments.

What kind of adjustments?

[splitbrain]

The client is now namespaced \dokuwiki\Remote\IXR\Client and no longer inherits from HTTPClient but from the original IXR Client.

It's no longer possible to set the debug parameter, as shown in the demos:
https://www.dokuwiki.org/devel:xmlrpc:clients
It throws one of two errors, depending on whether you use the setDebug method or set the property directly using $client->debug.

Error: Call to undefined method dokuwiki\Remote\IXR\Client::setDebug()
Error: Cannot access protected property dokuwiki\Remote\IXR\Client::$debug

It turns out that the debug value was a function of HTTPClient.

docs will need to be adjusted. you can call getHttpClient() and set debugging on that

[turnermm]

Thanks. Works perfectly. I'll update the docs.

[turnermm]

But I'll wait until the new code is merged.

@turnermm Do you have the opportunity to update the docs? If you are done, could you remove the label please?

[turnermm]

Docs have been updated
https://www.dokuwiki.org/devel:xmlrpc:clients#sample_php_client

I can't remove label. I guess splitbrain has to do that since he added the label.

[turnermm]

Ah, I see you not splitbrain added the tlo-do label

[Klap-in]

Thanks!
