This patch takes care of:
* Consistent behaviour during create, update operation on any node.
- It should return the node data during creating a new object, or
updating the existing one.
* Now that - we have consistent behaviour during these operations, we
can consistently move, update the tree item based the node data from
the server.
* Implemented the methods for each node to get the information about
that particular node only.
* Using the above changes to implement the 'refresh' operation on tree
node properly.
I must thank Surinder, and Harshal for helping me implement the 'node'
method, and also changed the behaviour of create & update methods to
return the node data for most of the nodes.
Fixes#1244
Made backend changes for:
* Taking care of the connection status in the psycopg2 driver. And, when
the connection is lost, it throws a exception with 503 http status
message, and connection lost information in it.
* Allowing the flask application to propagate the exceptions even in the
release mode.
* Utilising the existing password (while reconnection, if not
disconnected explicitly).
* Introduced a new ajax response message 'service_unavailable' (http
status code: 503), which suggests temporary service unavailable.
Client (front-end) changes:
* To handle the connection lost of a database server for different
operations by generating proper events, and handle them properly.
Removed the connection status check code from different nodes, so that
- it generates the proper exception, when accessing the non-alive
connection.
Fixes#1387
* Hide the security tab for the objects under the catalog schema.
Patched by Surinder Kumar, vastly improved by me.
* Make the securtiy label across all the nodes, using the same backbone
model across the nodes, and make changes in the backend code for the
same.
- Don't display the OID on Edit dialogues
- Use the ACL summary display in the properties panel, not the subnode editor.
- s/Oid/OID/g
- Ensure all security properties are displayed in the Security group
- Ensure all object definition values are stored in the Definition (or a more precise) group, not General.
- Fix the ordering of General properties so the comment is always show last.
