[Dev] [IS 6.0.0] [SCIM 2.0] Extend SCIM2.0 meta data in the SCIM response to include User Life cycle State

[Indunil Upeksha Rathnayake]

Hi,

In IS 6.0.0 with SCIM 2.0 support, we are planning to Extend SCIM2.0 meta
data in the SCIM response to include User Life cycle State. Currently, in
database level, "state" parameter is getting saved in the "IDM_USER" table
(Refer [1]).

As per the SCIM2 Core specification(Refer [2]), there are specifically
defined sub attributes for the "meta" attribute. So that, I think it's
invalid to include "state" inside the meta attributes in the response as
below.

"meta":{*"state":"CREATED"*, "created":"2017-02-28T11:50:12Z","location":"
http://localhost:9292/scim/v2/Users/1.945a6def-d139-4abc-9090-e4dd10217580";,
"lastModified":"2017-02-28T11:50:12Z","resourceType":"User"}

"state" is not defined as a core attribute in the specification, so that it
need to be considered as an extended attribute and need to be added from a
SCIM extension. If so, "state" can't be added for the list of meta
attributes since, extended attributes are kept in their own sub-attribute
namespace identified by the schema extension URI [2].

Is it appropriate to add "state" attribute from a SCIM extension and add it
to the response separately as below?

{"meta":{"created":"2017-02-28T11:50:12Z","location":"
http://localhost:9292/scim/v2/Users/1.945a6def-d139-4abc-9090-e4dd10217580";,
"lastModified":"2017-02-28T11:50:12Z","resourceType":"User"},"schemas":[
"urn:ietf:params:scim:schemas:core:2.0:User",
"urn:ietf:params:scim:schemas:extension:enterprise:2.0:User"],"name":{
"familyName":"user1"},"id":"1.945a6def-d139-4abc-9090-e4dd10217580",
"userName":"user1", *"EnterpriseUser"**:{"state":"CREATED"}*}

Appreciate your ideas.

Meta attributes are common set of attributes shared across all entities
such as User, Group ...etc. IMO we shouldn't and we can't include "state"
attribute under meta attributes.

[Dev] [IS 6.0.0] [SCIM 2.0] SCIM meta attributes directly get connected to User object

[Indunil Upeksha Rathnayake]

hi,

As per the SCIM 2.0 Core specification (Refer [1]), there are *resource
meta attributes such as resourceType, created, lastModified, location and
version* which are Common Attributes for all the resources.
As in the specification: "*Each SCIM resource (Users, Groups, etc.)
includes the following common attributes.  With the exception of the
"ServiceProviderConfig" and "ResourceType" server discovery endpoints and
their associated resources, these attributes MUST be defined for all
resources, including any extended resource types.*".

Currently the SCIM meta attributes of a user, saved in the
"UM_USER_ATTRIBUTES" table with the other user attributes. We are planning
to move all the SCIM meta attributes to "IDM_USER" table([2]) and make it
part of User, basically this is to have performance improvements when
querying for list users(in list users need only to return meta data unless
client specifically asks for other attributes) etc.

But is it correct to move the meta attributes to "IDM_USER" table, since
those are common attributes which are not directly related to the "User"
Resource Schema?

Appreciate your idea on this.

Re: [Dev] [GSoC 2017][ESB]Native inbound and connector for IBM MQ 8.0

[Chanaka Balasooriya]

Hi Malaka,

Thank you for your response.

As you mentioned, to understand the advantage of using native IBM MQ jars I
will need to compare the current ESB IBM MQ support with native IBM MQ.
So please share if you have any recommended reading materials to know more
about IBM MQ other than [1] and it will be really helpful to get a better
approach to this project.

(I do confirm that I am a full time student and eligible to participate
GSoC. )

Re: [Dev] Adding IoTs quick-start script

[Susinda Perera]

Hi Shavindri

The mobile-qsg is packed with IoTs core and will be available with the next
release.
Steps to run the QSG script is simplified as follows
Start the server,
Navigate to /core/samples/mobile-qsg
Run mobile-qsg.sh and observe the outcome.

Now we don't have to host this to be downloaded as it comes with the pack.
We may need to change the docs accordingly for the 3.1.0 release.

Thanks
Susinda

Re: [Dev] GSoC 2017 - Proposal 8: CLI tool for WSO2 API Manager

[Pubudu Gunatilaka]

Hi Ayeshmantha,

Thank you for your interest and good progress on the work.

As you have some experience in using API Manager, you can also go through
the API Manager concepts [1] and get familiar with them. Additionally, you
can try out API export/import feature [2] and the API Manager 2.1.0 REST
APIs [3] to tryout the product.

Currently, WSO2 API Manager team is working on Carbon 5(C5) based API
Manager implementation and you can find the relevant repos in [4] and [5].
When you are developing the CLI, you should use the C5 REST APIs. API
Manager team has already added most important REST APIs and we are working
on adding new REST APIs based on the functionalities. Meantime, you can
also get familiar with GO language and learn the concepts.

As described in the project description you need to develop a CLI tool for
API Manager. You can also check the available CLI tools and get an idea how
you can develop the CLI in a more user-friendly way.

[Dev] GSoC 2017

[Dhanuka]

Hello everyone, My name is Dhanuka. And I'm a final year computer 
science student from Open University of Sri Lanka. I'm really looking 
forward to contributing to wso2 as a GSoC student. I found a particular 
project that I'm really interested in. Proposal 5: Eclipse plug-in for 
Siddhi; Because my interest in Java and Eclipse. And I think it's really 
awesome that I can create something that whole eclipse community can use.


And I've gone through the reference [1] and got some idea about eclipse 
plug-in development. And I would be so grateful to you if you can tell 
me more about this project and it's outcome.

Thank you.

Re: [Dev] GSoC 2017

[Tishan Dahanayakage]

HI Dhanuka,

Thank you for your interest in WSO2 and also the project. I am adding
possible mentors to the mail.
Siddhi is a SQL like language where you can write queries which can do
real-time analysis. Deliverable of the project is to develop an eclipse
editor plugin which has systax highlighting, code completion, running and
debugging Siddhi from within eclipse.
As starters I would say you start off by developing an eclipse plugin with
syntax highlighting capabilities for a simple antler based grammar. then we
can improve on that.

Thanks
/Tishan

[Dev] [MB] JMS session recovery causing messages which are buffered to move into the DLC before it's being received

[Pamod Sylvester]

Hi All,

Based on the issue mentioned in the $subject and described in [1] . Here's
what we discussed,

*Issue Summary*

During an error, when recover() session is called by the consumer (i.e jms
client/ESB), all unacked messages gets re-tried. This includes the messages
which were received by the JMS consumer as well as the messages which were
buffered in the client.

As a result, the messages which were buffered in the client and which have
not being received by the consumer get's diverted to the DLC after the
retry count has being breached.

*Problem Description*

The could also be described as a gap between the AMQP and the JMS
specifications. According to the AMQP the messages should be sent to the
client as a batch. Though JMS provides a way to acknowledge messages
individually. It doesn't provide a way to rollback an individual message.

The only option is to recover the whole session, when the client choses to
recover() the corresponding channel id of the client is sent to the broker,
for it to recover all unacknowledged messages. When the server recovers
unacked messages it will include the messages which were received by the
JMS client as well messages which are buffered in the client and which were
not received.

*Proposed Solution*

One way of solving this is through the following steps,

*Andes client side changes *

 1. When recover() is called from the client, distinguish the difference
between the received messages and the messages which are buffered. We've
done something similar for the rollback operation.
 2. The messages which were received by the JMS client, could be explicitly
rejected(). Sending a null ack for the message to the server. Since this
messages need to be retried for the given number of times.
 3. Once the rejection is sent the server will re-schedule the message
until the max retry count is reached in the

*server side changes*

When session recover is called in the broker,

*AndesSubscription.recoverMessages()*

We could maintain a seperate flag for each *DeliverableAndesMetadata *object.
So that when it's being re-scheduled for delivery, in the
*MaximumNumOfDeliveryRule.evaluate()
*would filter out these messages and will not increase the
*maximumRedeliveryTimes
*for the message.

The above is one way we could solve the problem. Would there be any
implications to it ? or will there be a better way of solving this?  wdyt ?

Thanks,
Pamod

More than looking at it as performance improvement, I would look at it as
an inherent part of the user object. There can't exist a user object
without filling the metadata attributes. Therefore it is only logical to
store it along the global UUID in IDM_USER table. Performance improvement
is just a added benefit we get. I didn't look at it from the POV of
performance initially. I looked at it and thought it makes sense to have it
in IDM_USER even if we forget about performance improvement.

I am not saying it should be part of the same table we have. If we need to
normalize it I understand that it may go to a separate table and we may
have to do a join in order to get the full user object; in which case we
may loose some performance. Still I think its logical to have it in our
internal tables rather than the identity store. Having it in the identity
store will drastically impact performance compared to join of two tables
because it is two JDBC calls or one JDBC and one LDAP call.

Having it in the identity store can be an option; similar to how Isura
designed it for the state value - we always keep the state value in the
IDM_USER table, but user has the option to update the state value in the
identity store if it supports that attribute through a lifecycle executor
in addition to the filed that we maintain. For all internal functionality
we only depend on the field that we maintain in out tables.

 hi,

 As per the SCIM 2.0 Core specification (Refer [1]), there are *resource
 meta attributes such as resourceType, created, lastModified, location and
 version* which are Common Attributes for all the resources.
 As in the specification: "*Each SCIM resource (Users, Groups, etc.)
 includes the following common attributes.  With the exception of the
 "ServiceProviderConfig" and "ResourceType" server discovery endpoints and
 their associated resources, these attributes MUST be defined for all
 resources, including any extended resource types.*".

 Currently the SCIM meta attributes of a user, saved in the
 "UM_USER_ATTRIBUTES" table with the other user attributes. We are planning
 to move all the SCIM meta attributes to "IDM_USER" table([2]) and make it
 part of User, basically this is to have performance improvements when
 querying for list users(in list users need only to return meta data unless
 client specifically asks for other attributes) etc.

 But is it correct to move the meta attributes to "IDM_USER" table,
 since those are common attributes which are not directly related to the
 "User" Resource Schema?

 Appreciate your idea on this.

[Dev] [IS] Starting over authentication flow as a different user

[Pulasthi Mahawithana]

In IS 5.3.0, I have configured the authentication flow for an application
to have 3 steps. During the authentication flow, the users may remember the
result of the first two steps (using cookies) in their initial login. So,
in subsequent logins they'll see the third step straight away in which they
always need to get authenticated.

Let's say 'Alice' logs in and remember the result for the first two steps
and finish her work. After some time 'Bob' also use the same browser and
try to login. He won't see the first two steps because there is an already
remembered result from Alice's login. But in the third step he can't
authenticate because he doesn't know Alice's credentials (and he intend to
login as 'Bob'). So he needs to start over the flow as 'Bob'. When he does
so, at IS, we should clear the remembered results for 'Alice' and allow the
the user to try with a different username (This time he should get
authenticated from all 3 steps). How can we achieve this requirement? Is
there a known approach?

Re: [Dev] [MB] JMS session recovery causing messages which are buffered to move into the DLC before it's being received

[Hasitha Hiranya]

Hi Pamod and all,

IMO, *we need both side's changes.*

Andes client - when receover() is called, send reject to application
consumed messages, and clear internal buffer
Server - while recovering, do not increase redelivery count (do not
consider as a redelivery, as app has not consumed). Redelivery header flag
is not needed as well.

Let us investigate and implement

Thanks

AFAIK we need to set the redelivered flag. I remember reading it in a spec

Not for messages that were in the andes client consumer buffer without
being actually consumed by the application.

 Yes. User stories and mails serve for two different purposes, isn't it?

Re: [Dev] [IS] Starting over authentication flow as a different user

[Thanuja Jayasinghe]

Hi Pulasthi,

The best approach is to ask Alice to log-out when she leaves the browser.

Or from the application side, we can give an option like "fresh-login"
which sends a "forceAuth=true" request to the IS. So he will go through the
authentication process again.

Thanks,
Thanuja

Re: [Dev] [MSF4J] Can we provide HTTP handler args in Interceptor level?

[Vidura Nanayakkara]

Hi Malintha,

As for the questions, you asked regarding the 1st approach I suggested:


* - Write a custom context provider of your own which will describe how the
injected value is generated by implementing a certain interface.In the
custom context provider, will we have access to the internal objects like
[1] so that we can use them to generate the custom context object?*

As per my understanding using approach 1 (custom context providers) it
would be a no. As I mentioned in the previous response, by default we can
access the Request, Response, HttpStreamer, FormParamIterator and
MultivaluedMap instances using the @Context annotation. If you need access
to the MSF4J internal objects like [1]
,
we need to make it accessible by default using the @Context annotation.

The purpose of the custom context provider is to help you inject custom
values by specifying the logic on how the value are generated (probably to
feed the arguments to your interceptors and the HTTP methods).

   - *Register the custom context provider to the MSF4J*
   - *Inject the value using @Context annotation (Ex:- @Context(String key)
   Object[] arguments)*

*Will it be possible to access the injected values within Interceptors?
Since one of our requirement is to come up with an Interceptor to validate
ETags in a central place, we need to access them within the Interceptor.*

Yes, this would be an enhancement to MSF4J (with or without custom context
provider implementation).

However, it would be great if we can have a discussion regarding this.

 Hi Vidura,

 I went through the links and the approaches you suggested and I have a
 couple of questions. I have also tried is to build the Request inside the
 Interceptor and get the Java method and the args from the Request (which
 was suggested during the offline discussion). For that, I tried to get this
 block of code [1] (which builds the request) inside the Interceptor. And
 that was successful, but I needed access to some of the internal objects in
 MSF4J request path. Ex: HttpResourceModel object [2]. They are not
 currently available in Interceptor level, so I had to modify ms4fj-core bit
 locally (just to check) to get them inside the Interceptor.

 Let's say we are following the approach 1.

- *Write a custom context provider of your own which will describe
how the injected value is generated by implementing a certain 
 interface.*

 In the custom context provider, will we have access to the internal
 objects like [1] so that we can use them to generate the custom context
 object?

- *Register the custom context provider to the MSF4J*
- *Inject the value using @Context annotation (Ex:- @Context(String
key) Object[] arguments)*

 Will it be possible to access the injected values within Interceptors?
 Since one of our requirement is to come up with an Interceptor to validate
 ETags in a central place, we need to access them within the Interceptor.

[Dev] [UUF] [IS-6] Update Google Guava version

[Ayesha Dissanayaka]

Hi,

Can we update guava.version and guava.version.range  [1] to match latest
released version(21) in next uuf release.

While writing UI tests for IS-6 User-Portal with selenium to resolve some
issues such as below one , I had to update above mentioned versions in
product-is.
[ERROR]
/home/ayesha/WORK/IS/SOURCE/PRODUCT_IS/product-is/portal/apps/org.wso2.carbon.iam.user-portal.app/src/test/java/org/wso2/carbon/iam/userportal/pageobject/PasswordRecoveryOptionsPage.java:[253,45]
no suitable method found for until(>)

But, again when running osgi tests I get below error, that uuf.core
requires previous version as dependency.
[2017-03-02 11:24:59,478] ERROR {org.wso2.carbon.uuf.core} - FrameworkEvent

Re: [Dev] [MSF4J] Can we provide HTTP handler args in Interceptor level?

[Vidura Nanayakkara]

Hi Azeez,

We had a discussion regarding this. Following are the solutions we decided

   - Set object handler as a property in the Request instance (just like we
   are setting the HTTP method according to [1]
   )

With this change you can access the handler through the Request instance
just like as shown below:

request.getProperty("HANDLER")


   - Include method arguments in the Request instance.

As for what we suggested in the previous discussion,

*I have also tried is to build the Request inside the Interceptor and get
the Java method and the args from the Request (which was suggested during
the offline discussion)*

With the pull request [1]  we are
building the Request before the interceptors are executed. So this is
handled.

WDYT?
