JSON API SysVar.deleteSysVarByName only softdeletes

[pmdevelopment]

To reproduce create a new SysVar, e.g. using SysVar.createEnum named "Test". Now call SysVar.deleteSysVarByName, the result shows success, SysVar.getAll won't list the variable anymore. Now create "Test" again, SysVar.getAll will show: it's listed as "Test 2", the original "Test" was only softdeleted. I couldn't figure out how to remove the original "Test" variable.

Creating and deleting using the WebUI will not reproduce this behaviour.

Please show an example payload with example response output and not just explain your issues with words. Show concrete examples!

Sure, payload for SysVar.createEnum:

"{"name":"Test","valList":"Foo;Bar;Other","internal":"0","chnID":"-1"}

Response is successful:

{"version": "1.1","result": {'name':'Test','id':'6968','value':'Foo;Bar;Other' },"error": null}

Payload for SysVar.deleteSysVarByName:

{"name":"Test"}

Response is successful:

{"version": "1.1","result": true,"error": null}

SysVar.getAll won't list the variable anymore, but e.g. SysVar.getValueByName will return:

{"version": "1.1","result": "0","error": null}

Asking for a non-existing variable would look like this:

{"name":"Foobar"} => {"version": "1.1","result": "","error": null}

Now the payload to create the variable again:

{"name":"Test","valList":"A;B;C","internal":"0","chnID":"-1"}

The response shows our variable was created with a new name to prevent the conflict with our soft-deleted one:

{"version": "1.1","result": {'name':'Test 2','id':'6971','value':'A;B;C' },"error": null}

I am almost certain that the issue just happens because you have another object (device, channel, program, etc.) that has also the name "Test". Unfortunately, the SysVar.getValueByName function does not filter for system variables but applies the search to all objects, that's why your request for a "Test" system variable still matches, simply because the getValueByName function is doing the search wrong. This is something I will try to fix/optimized in RaspberryMatic.

It's definitly not because of "Test", my original Parameter was "APP_VENTILATION_STATUS". If you create, delete and recreate the same Systemvariable in the WebUI, the name won't add a number, it's only this behaviour with the JSON API.

I think the SysVar methods for the JSON API are just not used very often, i guess most software will program the channels directly instead of using a system variable change to trigger programs.
