Re: [Dev] Adding a user with '@' sign (username == test@user) without enable Email User

[Nuwan Dias]

IMO we should set  to 'true' in carbon.xml to be able
to create users in the form of u...@email.com. My opinion is that we should
prevent entering those type of usernames if that config is 'false'.

Thanks,
NuwanD.

[Dev] Can we use Snakeyaml 1.17 in Carbon 5.1.0?

[Isuru Perera]

Hi Carbon Team,

I noticed that there is a new version for snakeyaml [1]. Do you usually
check your dependencies before releasing a new Carbon Kernel version?

Re: [Dev] SnakeYAML is already an OSGi bundle. Why do we have SnakeYAML in orbit?

[Isuru Perera]

Thanks for info.

Shall we ask the snakeyaml developers to add the Dynamic-Import header. May
be we can create an issue [1]. Otherwise, that library is not useful in an
OSGi container, right?

[Niranjan Karunanandham]

Hi Isuru,

+1 to upgrade the snakeyaml version. IMO it would be better to upgrade the
version, but before that we need to verify if there has been any API
changes (since it is a minor release).

Regards,
Nira

Re: [Dev] [DEV] [VOTE] WSO2 Developer Studio Kernel RC3

[Awanthika Senarath]

Hi Nuwan ,

Please find my inline comments,

Please note that all three bugs reported are not related to Kernel, but to
Developer Studio Tooling Platform, RC2 of Tooling Platform will be released
today for voting.

https://wso2.org/jira/browse/TOOLS-3413

This has already been fixed in the latest Platform RC released this
morning, with which version of platform did you test? Please install the
latest Platform Tooling versions from [1] and confirm if the issue exist. I
have tested with [1] and could not reproduce.
https://wso2.org/jira/browse/TOOLS-3412

This is a linux specific issue, and I will look into this.

https://wso2.org/jira/browse/TOOLS-3411

This has been changed and committed in the latest Platform Release RC

Re: [Dev] [DevStudio] How to retrieve DevStudio kernel key store certificates?

[Awanthika Senarath]

Hi Thilini,

With the eclipse migration to Mars, we cannot use the system property JKS
parameters, Eclipse has removed this facility from Mars onwards.

The recommended approach is to set a Trust all manager for your connection,
Please refer commit at [1] at class CloudAdminServiceClient for an example
of the implementation required to fix the issue mentioned.

[Dev] [Architecture] [BPS] [UUF] Developing BPMN Explorer UI using UUF for BPS

[Sudharma Subasinghe]

Hi all,

I am working on developing BPMN explorer ui using Unified UI Framework.

The existing BPMN explorer ui is for BPS which has built on C4 and it is
used Jaggery. So, I am working on BPMN explorer ui for BPS which is to be
released on C5.

We need to implement business logics in backend. For example, I need to
send request to backend from browser, and from backend to BPS. Is there
functionality to achieve it in UUF?

Any idea on this is appreciated.

Thanks
Sudharma

+1. IIRC current behavior was not there in Kernel 4.2.0 products.

@IS team: was there any special reason to introduce this? As Dhanuka
mentioned above, this leads to ambiguity between user *a...@x.com
* of *super tenant* and user* abc* from tenant* x.com
. *And the most critical issue here is if we have a user
*a...@x.com
* in super tenant, it will break all the places where it uses
*MultitenantUtils.getTenantAwareUsername. *So we need to come to a decision
about this soon.

That's great Abhishek.

You can build the docker images using puppet provisioning for Kubernetes
platform and try to deploy in Kubernetes,
you can follow the steps provided in the docs [1]. It is very easy to
follow.

[Dev] Why there is a TestNG version 6.9.11 in WSO2 Maven Repo??

[Isuru Perera]

Hi,

I noticed that there is a TestNG version 6.9.11 in WSO2 Maven Repo.

The latest TestNG version is 6.9.10 [2, 3].

I usually use "mvn versions:display-dependency-updates" to update my
dependencies and I thought TestNG 6.9.11 is the latest version.

I had an issue with Pax Exam OSGi tests and the build was not failing if
there is an assertion error in TestNG 6.9.11.

However that issue is solved when using the TestNG 6.9.10.

I was checking on this issue for few days because of the this unknown
TestNG version in WSO2 Maven Repo! :(

Re: [Dev] [Architecture] [BPS] [UUF] Developing BPMN Explorer UI using UUF for BPS

[SajithAR Ariyarathna]

Hi Sudharma,

In the browser (client-side), you can do AJAX calls to the necessary REST
APIs. However, doing HTTP requests from UI backend (which runs on the
server-side) to REST APIs (which also runs on the server-side) is not
recommended. Instead of that you should call OSGi services. Calling OSGI
services from server-side JS will be available in the next milestone of UUF.

Thanks.

[Dev] [BPS][Tooling] Version numbers for product based Tooling releases

[Heshitha Hettihewa]

Hi all,

Currently I'm in the process of developing BPS Tooling for Developer
Studio.For the product based Tooling releases like these what is the most
appropriate version number?. As this is the first BPS tooling release
should it be 1.0.0 or should it be a version related to current dev studio
version (4.1.0) ?.

Thanks.

[Dev] SAML 2.0 Single Logout Profile Response handling for AS 6.0.0

[Chiranga Alwis]

Hi,

I have been working on porting the past AS SAML 2.0 based single-sign-on
valve to the new AS version.

When refactoring and testing the already ported code, I came across the
following issue within the invoke() method of the SAML 2.0 SSO Tomcat Valve
[1].

In the group of if-then and if-then-else statements which handle the SAML
2.0 Web Browser SSO and Single-Logout Profiles, I find the following code
block which the program flow does not seem to enter within simple sign-in
and logout processes.

if (resolver.isSLORequest()) {

if (log.isDebugEnabled()) {
log.debug("Processing Single Log Out Request");
}
samlSSOManager = new SAML2SSOManager(ssoAgentConfig);
samlSSOManager.doSLO(request);

} else if (resolver.isSAML2SSOResponse()) {


During debugging of the past AS 5.3.0 implementation and my current
implementation, I have experienced that this block is never executed.

In addition, the implementation of the resolver.isSLORequest() method in
[2] has changed in latest versions and the carbon-identity version 4.5.6
(used in AS 5.3.0) possesses an older implementation [3]. I tried adopting
the new implementation which leads to an error during handling of
Single-Logout responses from the side of Identity Server.

Are there any scenarios which led to the introduction of the above
mentioned logic when performing SSO? Any suggestions or ideas are highly
appreciated.

[1] - SAMLSSOValve.java

[2] - SSOAgentRequestResolver.java

[3] - SSOAgentRequestResolver.java

 Credentials might be correct, I think the issue is with the
 permission. You might need to grant permission to the relevant 
 databases to
 your user for the given IP address. Please refer [1].

Hi All,

For clarification, does this mean we will be able to invoke a service side
function(through nashorn) upon client request ? As in when a user clicks a
button, we can call a server side function ?

[Dev] Time series data summarization

[Dulitha Wijewantha]

Hi guys,
I have a bunch of data streams that have time stamps (like event logs) -
currently in DAS 3.0.1 - is there a way to efficiently query these?

Right now I am summarizing them based on string manipulation to the
timestamp. An example query I have is -

1) How many unique user events do we have in the last year.

Cheers~

I'm using OAuth2TokenValidationService to validate the token.

schedule a spark query that aggregate the data per year and write to new
table, and you can query from that table?

To add to what Srinath said.
If you enable indexing for that summary table, you'll be able to get the
data through the REST API as well using lucene queries,.

Re: [Dev] GSOC 2016 - Project 21 : MongoDB Userstore Development

[Asantha Thilina]

Hi Tharindu,

sorry for the late reply ,as you advised i remove the scr reference and its
corresponding methods from user store now it's works fine but i having
another small issue if i wanted to run my mongodb user store as as my
primary user store how would i do that?
i added my user store configurations to user-mgt.xml file and comented the
ldap userstore properties and i added MongoDBUserStore to tenant-mgt.xml as
well but then i get error as datasource cannot be casted to MongoDB db
source while deploying thats mean its still referring to Default Activator
inside carbon core module how would i set it to my activator to reffer?
any suggestion or help would be grateful
Thanks,
Asantha

 Hi Tharindu,

 since mongodb driver not having prepared statement support earlier i
 developed a logic to support prepared statement but i realized that it has
 a limitation such as parameters has to be pass as same order it exists in
 prepared statement then as you suggested to use key value relationship
 instead of order during our hangout conversation i created a new logic same
 to prepared statement in sql and it will work according to key value
 relationship and i created standard query format for mongodb with json to
 support prepared statements and i rewrite the JDBCRealmConstants class with
 those supporting json queries instead of sql queries

 All of my prepared statement methods contain in
 MongoDBPreparedStatement interface and its implementation in
 MongoDBPreparedStatementImpl class

 All the changes i have pushed to my repo in here[1]

 security of this prepared statements has to be improve

 I'll be grateful if you can provide me some suggestions to improve it
 and also another small issue i having is can i write a DataSource for
 MongoDB as in java.sql.DataSource ?

Re: [Dev] [Jaggery] Web sockets api in jaggery

[Sinthuja Ragendran]

Hi Dhanushka,

You don't need to do any special changes, just include the server side code
as shown in the sample [1] in a jag file, and mention that jag URL in the
client side to connect via web socket. As per the example, the jaggery app
for ws server side should be in below format.

- sample
   - ws
   - server.jag

Thanks,
Sinthuja.

Hi all,

Does web sockets work through nginx, haproxy like load balancers?

[Dev] Clarification on Availability of API

[Shavantha Weerasinghe]

Hi All

When APIs are invoked continuously, the availability of the same API is
shown as available and also  busy. Is this the expected behavior or should
the only 1 status be shown for an API at one time

admin--TestAPO:v1.0.0Available*admin--PizzaShackAPI:v1.0.0*AvailableTestAPO:v1.0.0Response
time is too high*PizzaShackAPI:v1.0.0*Response time is too
highCalculatorAPI:v1.0Available

[Dev] Automation Script to check if feature/update successfully copied to P2 repository

[Awanthika Senarath]

scenario;

I am writing an automated script for $subject using P2 director

For the P2 director we cannot give the feature with a version, we have to
give only the feature name,

When we give the feature with the releases repository URL it will also
check in the updates repository and will install the latest version of that
feature available in the whole repository.

Therefore we can give the releases URL and ask to install the feature we
give, so that it will isntall the latest available version of that feature
in updates/releases.

what we can do is to give the feature ID with the released repository URL.
But then again we cannot give the version and cannot verify whether the
feature we gave is installed or not.

I have checked the headless feature installation in eclipse via command
line, but that does not support installation of features with versions.

Any idea how to proceed?

There are couple of phase in this test scenario , in the first phase,we can
verify that given release/update version of a feature is available in the
p2 repo then we can execute this test script to install latest version of
that feature, so we don't want to specify the version again, after this
phase , we need to have SWT_BOT based test case to validate the
functionality of that feature

Re: [Dev] Automation Script to check if feature/update successfully copied to P2 repository

[Awanthika Senarath]

Yes, but say we have updated kernel feature version 3, kernel feature 1 and
2 are already available viea releases and previous updates

this script will run and give success installing kernel feature 2 even if
kernel feature 3 that was copied is corrupted,

then the whole purpose of the script is not achieved right?

this will only guarantee that the given feature is available in the
repository with whatever version.

Re: [Dev] [Architecture] [BPS] [UUF] Developing BPMN Explorer UI using UUF for BPS

So there is not separation between UI back-end and the actual server (e.g.

 Hi all,

 I am working on developing BPMN explorer ui using Unified UI Framework.

 The existing BPMN explorer ui is for BPS which has built on C4 and it
 is used Jaggery. So, I am working on BPMN explorer ui for BPS which is to
 be released on C5.

 We need to implement business logics in backend. For example, I need to
 send request to backend from browser, and from backend to BPS. Is there
 functionality to achieve it in UUF?

 Any idea on this is appreciated.

 Thanks
 Sudharma

Yes, there's possibility for this to happen since the p2 query for checking
the feature version in first phase is only reading the metadata repository.
Only at the install phase, artifact repository will be read.

Re: [Dev] [Architecture] [BPS] [UUF] Developing BPMN Explorer UI using UUF for BPS

[Rasika Perera]

Hi,

We have came up with this best practise. There are basically two scenarios;

1. When the back-end is belongs to your product(eg. calling BPS runtime).

We assume that you have written your JAX-RS based on an OSGi service.
JAX-RS will *not* hold any business logic and act as API interface(Facade
Pattern). In this case making a network call(AJAX) from UI to your own VM
is discouraged. You should use callOsgiService() function on the server
side Js.

2. When the back-end is external(eg. calling Twitter API).

Here we don't provide any server side feature for handling HTTP calls
because this will again abuse and use to call own VM back-ends. You can
simply write AJAX calls from UI using $.ajax() in jquery or XMLHttpRequest
in client-side Js.

* In the edge cases that you really need to make HTTP calls from the server
side Js, you can initiate; apache commons 'HttpClient' or java.net
'URLConnection' through Nashorn.

* Also you might still need to write JAX-RS APIs for your OSGi services for
customers.

Thanks,
Rasika

 Hi Sudharma,

 In the browser (client-side), you can do AJAX calls to the necessary
 REST APIs. However, doing HTTP requests from UI backend (which runs on the
 server-side) to REST APIs (which also runs on the server-side) is not
 recommended. Instead of that you should call OSGi services. Calling OSGI
 services from server-side JS will be available in the next milestone of 
 UUF.

 Thanks.

Re: [Dev] [Architecture] [BPS] [UUF] Developing BPMN Explorer UI using UUF for BPS

[Nandika Jayawardana]

In case of BPS, what we develop is similar to a web application which
should be independent of the BPS backend. Idea is that this component has
to be packaged into PC ( process center ) as well as BPS. Hence, native
OSGi call's is not sufficient for our requirement.

Nandika

Re: [Dev] Clarification on Availability of API

[Fazlan Nazeem]

Hi Shavantha,

We are using both the request and response stream in order to check the
availability of an API. We identified a bug in API-M where the api_version
takes two different values as in the screenshot, for the request and the
response stream of the same API. Thanks for reporting this issue. I have
created a Jira[1] in API-M to track this.

Re: [Dev] [Jaggery] Web sockets api in jaggery

[Danushka Fernando]

My log file rolled and tail got expired thats why I saw no logs. Actually
problem is my jaggery call to modules. I am getting exception below.

var logMap = mod.getFormattedRuntimeLogs(applicationKey, selectedRevision, "");

Is there a way to ged rid of this?

Re: [Dev] Time series data summarization

[Niranda Perera]

Hi Chan,

Agree with the above comments. Additionally, you can refer to the log
analyzer scenarios as well, because I feel like their use case is somewhat
similar to yours.
