QGIS_Plugin_Check WCPS plugin can work with QGIS 3.x

Check if Rasdaman's QGIS plugin can work with QGIS 3.x

https://plugins.qgis.org/plugins/QgsWcpsClient1/

from this email

the Release of QGIS 3.0 was a great success and with the first LTR (3.4)
scheduled for release this fall, it is now the perfect time to port your
plugins to the new API, if you did not do it already.
I'd like to share a new tool created to help plugin developers porting
their plugins to QGIS3.
It is called it qgis2to3 and you can install it via pip by running

  pip install qgis2to3 (on some system this might need sudo)

once installed,  two new commands will be available on you system:
- qgis2to3 (a copy of the files found in
https://github.com/qgis/QGIS/tree/master/scripts to allow for quick
downloading and simple installation)
- qgis2apifinder (a tool based on qgis.org/api/api_break.html that helps
you find usages of the QGIS API version 2 and gives hint on how to adapt
the code for API version 3)
Documentation and source code are at
https://github.com/opengisch/qgis2to3
a blog post with more suggestions on how to port can be found here:

First check that the current version (for QGIS 2.x) can work with latest rasdaman.

Replying to dmisev:

First check that the current version (for QGIS 2.x) can work with latest rasdaman.

​https://imgur.com/a/QejWL it can work with latest Petascope and QGIS v2.14

[Bang Pham Huu]

However, the latest version QGIS in centos 7 is just 2.14

yum list qgis

[rasdaman@localhost rasdaman]$ 

I think to update to version 3.0 should be deferred.

@Dragi: First you need to install QGIS ​https://qgis.org/en/site/forusers/download.html version 3.2 and then install this WCPS1 plugin: ​http://rasdaman.org/wiki/Clients#QGISWebGIS to test if it still works, if it is not, update as the ticket description.

On QGIS 3.3 it gives this

This plugin is incompatible with this version of QGIS
Plugin designed for QGIS 2.0 - 2.99

[Dimitar Misev]

Right, so the plugin needs to be updated to be compatible with QGIS 3.

[dkamov]

After trying to adjust the plugin for QGIS 3 I got to the following error where I didn't know how to continue and so I emailed the QGIS developers team but they didn't contact me back…
The error is:

TypeError: qRegisterResourceData(int, str, str, str): argument 2 has unexpected type 'str'

So Dragi can continue his task last year.
