Re: [Dev] [Automation Framework]

[Malaka Silva]

Hi,

It seems this is a requirement for ESB integration tests not for ESB
Connector test.

Ideally we should have a different version for connectors in integration
base.

[Dev] [App Cloud] Custom Applications on AppCloud

[Nishadi Kirielle]

Hi all,
I am currently working on allowing users to upload custom applications
types to app cloud with the user specified docker urls. As for now this
feature is expected to be exposed only to internal users by updating the
configuration file.

Any suggestions on this feature are highly appreciated.

Thanks

This functionality is already present in the ES.The search query supports
all attributes present in the RXT definition.

If so, how can I prevent this to show the search results once the user

Can you please provide the following details:

   - From which page are you performing the search?
   - Can you please provide a link/source to the custom template files and
   the client side JavaScript used to implement the functionality?


Thank You,

 Hi Devs,

 We are in the process of upgrading the Carbon Kernel version to 4.4.5

 During this upgrade we found out that
 "org.wso2.carbon.identity.provisioning.connector.salesforce.server" feature
 is dependenct on a non-existing feature version of
 "org.wso2.carbon.databridge.commons.server"

 I opened a Jira to track this. [1]

 Had a chat with Pulasthi and this will be fixed with IS 5.2.0 release
 which will happen in the next week.

 Until this is fixed, I'm proceeding with the identity 5.0.9-SNAPSHOT
 having the issue fixed locally.

 Thanks
 Rushmin

[Dev] [ES][PC] Prevent automatic redirection in form submission in Process Center

[Dilini Mihindra]

Hi all,

I am currently working on an advance search functionality in the Process
Center. Instead of searching a process by name only, when a user adds a
sub-process for a new process, I am implementing the functionality to do an
advance search using more filters (ex: name, version, owner, description
etc.)

However, when I enter a value in one of the search fields and click the
search button or press enter, the response is redirected to the following.

*https://localhost:9443/publisher/assets/process/create?process-name=abc==
*

Is this something default provided by ES? If so, how can I prevent this to
show the search results once the user submits the form? Any help would be
highly appreciated.

Thank you.

Re: [Dev] [DAS] Is there a way to retrieve selected fields from a given table

[Gimantha Bandara]

Hi all,

We have added an extra query parameter to  "get" operation and a JSON
element called "columns" to "search" and "drilldown" operations.


*Get the records from a table*

GET /analytics/tables/{tableName}?columns=column1,column2,column3

*Drilldown and Search APIs*

Additional JSON element will be added as following

POST /analytics/drilldown or POST /analytics/search

{
  "tableName" : ,
   
   
  "columns: ["column1", column2", column3"]
}

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Gimantha Bandara]

Please note that "fields" is changed to "columns" for consistency as in
APIs, "columns" is used.

 Hi Sanjeewa,

 Thank you for the guidelines doc. The exact problem is discussed in
 10.2 in the above document. We will be filtering the record values in each
 records by providing the required columns, so only those column values will
 be returned with each record. According to the document the POST can be
 used either for updating/creating a resource or for initializing a
 processing function. In our case we will be simply retrieving records but
 need to provide a filter for the record values. So from users perspective,
 it will be doing some processing and returning filtered records.

 We can actually implement the following url, but we cannot exactly say
 if it will exceed the url length limit.
 GET /analytics/tables/{tableName}?columns=column1,column2]

 Or we can implement something like below,

 POST /analytics/tables/tableName/

 {
   from:
   to:
   start:
   count:
   columns :[c1,c2,c3]
 }

 or

 POST /analytics/

 {
   tableName :
   from:
   to:
   start:
   count:
   columns :[c1,c2,c3]
 }

 Considering the url length limit, I think the second option is better.
 WDYT?

Re: [Dev] Unable to send SOAP call.

Hi Chiranga,

While debugging the code, I found that the class loader did not find the
package 'org.apache.axis2.saaj.SOAPConnectionFactoryImpl'. It throws the
class not found exception like
"*org.apache.axis2.saaj.SOAPConnectionFactoryImpl
cannot be found by geronimo-saaj_1.3_spec_1.0.0.wso2v3".*

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Gimantha Bandara]

Hi all,

Thank you for your suggestions! We are going to use GET with the query
parameter "columns" to get the records filtered by a time range. So when
only a selected set of columns/fields are needed, Following format can be
used.

*Get the records within a specific time range.*

GET
/analytics/tables/{tableName}/{to}/{from}/{start}/{count}?fields=field1,field2,field3

*Drilldown and Search APIs*

Additional JSON element will be added as following

POST /analytics/drilldown or POST /analytics/search

{
  "tableName" : ,
   
   
  "fields: ["field1", field2", field3"]
}

 Hi Gimantha,
 Did you refer REST API guidelines document attached in this mail[1] in
 architecture mailing list.
 When we develop REST APIs please follow that document and if you see
 anything missed there please let us know.

 [1][Architecture] REST API Guidelines


 Thanks,
 sanjeewa.

[Dev] C5 - mention the port in use as part of error message

[Sumedha Rubasinghe]

It's port 8080 that is being used here. But no way to find that through the
exception through from
Netty HTTP Transport listener.

Re: [Dev] Kubernetes (and Openshift) modules

[Chamila De Alwis]

Hi Ramon,

One issue that can arise if a configuration step is introduced to Docker
images is the propagation of configuration changes in a running cluster. If
the configuration is done for a generic server at startup, the subsequent
changes to the config has to go live following either of two ways.

1. Kill the existing containers and let the PaaS healing component (ex: RC
in Kubernetes) to spawn new ones and let new config be applied to those
containers. This approach is the same for an already configured image.
2. Have some kind of an agent on the containers to poll and pull new config
to the existing containers. This approach is used in Apache Stratos, and it
tends to introduce another set of problems, when it comes to containers.

IMO, although the management of different, already configured, servers is
bit cumbersome, it can ease the already PaaS recommended approaches to
various problems at the cluster management layer. For example, Kubernetes
has a rolling-update, which takes an image name as the new version of the
server to gradually update the cluster. This encourages an immutable image
with changes that get written in to versioned images.

For the maintainability issue of the images, can a Puppet based image
building pipeline be applied? This would have a single Puppet server
(configuration automation layer) which would trigger (on demand or by a
hook of some kind) an image build with a certain set of parameters, that
would result in a (new version or an overwriting version for the) set of
Docker images in the local Docker registry. Additionally this event can
trigger another execution where the Kubernetes clusters are updated. This
way the configuration is preserved and effectively separated from the
images and image maintenance is simplified.
