algorithm.
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
Tweaked by Ashesh Vashi to integrate the backgroud process, and also
with some improvements as stated below:
* Resolved an issue loading existing preference.
* Improved the background process observer/executor for supporting
detalied view.
* Added the utility path preferences in the ServerType class.
Also - includes:
* Added 'parent_id' in the 'generate_browser_node' function of the Nodes
to allow them to move around the parents objects (specially through
update/save functionality).
* Handles the issue related to adding the older object back to the
collection (DataModel).

NodeListByNameCell for selecting the grantee.
This patch includes:
- Change the RolePrivilegesModel schema to allow to use the
NodeListByNameCell for showing grantee, and granter information.
- When setting some value - do not use the silent flag in Select2Cell, which
will allow the session manager to take the value in account, which is
used by the NodeListByNameCell.
- Set the top object in the children of the UniqueControl collections.
[Ashesh Vashi]
- Pass on the node information to the actual data model, so that - we can use
node information by the control itself. [Ashesh Vashi]
- While adding the new privilege, set the granter to the current user.

Thanks Harshal Dhumal for sharing the original patch.
I've modified a lot to work by fetching the variables later by giving a
url.
Also,
- Introduced the template macros for SECURITY LABELS and VARIABLES.
- Improvised the Backform.Control with better syntactic approach.
- Introduced a jquery function pgMakeVisible(..) to make it visible
under any obj which can be identified by unique class.
inputs.
In order to do the proper quoting around the identifier, different type,
and literal, we introduced respective functions qtIdent, qtTypeIdent,
qtLiteral in psycopg2 driver. Also, introduced them as the Jinja's
custom filter for using it directly inside the templates.
Also, created an utility - generate_keywords.py in order to generate
keyword lists from the latest PostgreSQL installation.
- Renamed the URL 'nodes' to 'children', because - we'll return the
children for the current node.
- Using the URL 'nodes' to fetch all nodes of its type, when not
specified the node-id, otherwise regenerate that node info using the
node-id (it will be used by the refresh function).
- Added the URL 'msql' for fetching modified SQL for the modified
objects.
- Separated the URL 'deps' (GET/POST methods) to 'dependency' and
'dependent', because - it will be used to fetch the properties of the
object, not manipulate it. (as suggested by Dave).
This commit includes the changes related to it in the specific nodes.
(i.e. server-group, and server).
Also, includes a javascript change to ask the user (if they really want
to leave the page, and it is not an accidental navigation by keyboard
shortcuts).
- Allow to release connection using the database OID (did).
- Generate correct url for the collection nodes.
- Removed the server-type from the collection node module, from the
generate_browser_collection_node(...) function.
- Show version string, and not version integer in the server properties
(when connected).
connect to the database server. Also, added modified the way, we do
check the node is supported by the server.
Instead of creating separate blueprint for the server types, they will
be independently works. In order to add different variant of the
PostgreSQL, we need to extend the ServerType class, and override the
'instanceOf' function for identification using version string. Please
take a look at the ppas.py for the example.
During checking the back-end support for the node, we will also check
the server type (variant) along with the version within the range of
maximum and minimum version for the node. And, the same support added
for the schema attributes in front-end (JavaScript).
Really thankful to Khushboo Vashi for her initial work in front-end. I
took it further from there.
