Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Hi All,

With related to the python cartridge agent , Dinesh and myself do some
research related to the Apache ActiveMQ connectivity using the python
client.

Following our findings on this.

*AMQP*

AFAWU we need to have  pyactivemq , which is a Python wrapper for the
ActiveMQ C++ Library,[1] But we won't be able to use this module as it is
platform dependent.
Also we checked the following client libraries as well(those
are recommended with the RabbitMQ)
[3] py-amqplib
[4] txAMQP
[5] pika
[6] Carrot (has copy right licence)

But we were unable to connect Apache ActiveMQ with those as well.(Even
through we can connect those with the RabbitMQ)

*STOMP[2]*

With the STOMP protocol , We were able to connect Apache ActiveMQ by using
the stomp module.[7]


As a summary,
It seems like we need to use STOMP to connect ActiveMQ. But still, WSO2
message broker is not supporting STOMP protocol.
IMO Shall we used the hybrid model for connect to the message queues. Such
that , we can use STOMP to connect the ActiveMQ and AMQP to connect WSO2
MB. WDYT?
With txAMQP[4] we were able to connect WSO2 MB using the qpid
amqp specifications.
Please share your suggestions and thoughts on this.

@Dinesh , Please add If I missed anything here.



Thanks,

Yeah. If we install libraries based on the platform (architecture and the
versions) , I think it is possible.

Currently do we have platform based library installations with new instance
spawning?

Thanks,
Gayan

Re: Stratos Python Cartridge Agent

[chris snow <ch...@gmail.com>]

I would have thought that puppet would abstract the installation of
the correct package for us:

- puppet will be defined to install the package 'qpid-proton'
- on ubuntu platforms, puppet will have the qpid-proton package
defined with a dependency that first adds the apt-repository
- on RHEL platforms, puppet will have the qpid-proton package defined
with a dependency that first adds the EPEL repository

The OS package management will take care of installing the package
with the correct architecture (32 or 64 bit) and on ubuntu installing
the correct version (trusty or precise).

WDYT?

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Thanks Chris.

My concern is if we used the binaries based on the platform ,every-time we
need to get the platform details of the instance when new instance going to
spawn and download the relevant binaries based on that platform.

As I noticed there are different set of binaries for the Ubuntu version as
well.

As an example Ubuntu 12 has following set of binaries[1].Those binaries
also based on the architecture.(eg binary-amd64,binary-i386 etc)
Ubuntu 14 has different set of binaries[2] with the different architectures.
So If we used this every time we need to check the platform architecture
with version details and get the correct binaries based on the platform
before start the cartridge agent on the newly spawned instance.

[1] http://ppa.launchpad.net/qpid/released/ubuntu/dists/precise/main/
[2] http://ppa.launchpad.net/qpid/released/ubuntu/dists/trusty/main/

Thanks,
Gayan

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

AFAIU we don't have make dist option here.I guess, they included the
install option only.Even if we have make dist option I guess still we need
to make a separate build for the each platform.Is n't?

Also that link[1],even it is about the qpid message broker, I think they
are talking about the same platform. WDYT?

Thanks,
Gayan

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Hi Chris,

AFAIR that build will added the attached file list (please find the
attached document) to the Ubuntu and it uses those files.IMO with fedora
build that files will be different and it will be platform dependent. WDYT?

Thanks,
Gayan

Re: Stratos Python Cartridge Agent

[chris snow <ch...@gmail.com>]

Ah, ok.  So the problem is just that we need to setup a development
environment to compile the qpid application?  After qpid has been
compiled to a binary, the development environment is no longer
required?  Can we use fedora to build a qpid binary for ubuntu?

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Yeah Chris.It is the command set for the fedora as mention in their read-me
file.

For Ubuntu we can use the following command sets.

# required dependencies
sudo apt-get install gcc cmake uuid-dev

# dependencies needed for ssl support
sudo apt-get install libssl-dev

# dependencies needed for bindings
sudo apt-get install swig python-dev ruby-dev php5-dev libperl-dev

sudo apt-get install oracle-java8-installer

sudo apt-get install python-epydoc

Thanks,
Gayan

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Hi Akila,

When we tried with the Apache Qpid Proton-C library we did the following
prerequisites.

    # required dependencies
    yum install gcc cmake libuuid-devel

    # dependencies needed for ssl support
    yum install openssl-devel

    # dependencies needed for bindings
    yum install swig python-devel ruby-devel php-devel perl-devel

    yum install java-1.8.0-openjdk-devel

    yum install epydoc


After that only we were able to build in the Ubuntu and run the python
client with proton support.I guess for every platform we need to do
the same and have to maintain different settings for different
platform.WDYT?


When it comes to the large number of instance, we need to do load
testing with the STOMP protocol.Thanks for pointing out this.



Thanks,

Gayan

Re: Stratos Python Cartridge Agent

[Akila Ravihansa Perera <ra...@wso2.com>]

Hi Gayan,

What are the concerns/blockers for using Apache Qpid Proton-C library
[1] with Python binding?

As I understood, this is cross-platform compatible (Linux/Windows) and
you do not need Java. However, there is a pure Java implementation but
we can use C/Python binding. We will have to investigate this further
though.

Have we made an analysis of using STOMP vs AMQP as the communication
protocol with MB for cartridge agent? We might have to consider this
because with the upcoming Docker support there can be about 1000+
instances communicating with the MB.

Re: Stratos Python Cartridge Agent

[chris snow <ch...@gmail.com>]

I guess the agent will need to be configurable to support STOMP for
ActiveMQ installations or AMQP for WSO2MB installations.

Also, I raised this JIRA:
https://issues.apache.org/jira/browse/AMQ-5332 - it won't happen in
our timescales, but I thought it was worth adding as it seems a lot of
people hit issues with ActiveMQ only supporting AMQP 1.0.

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Yeah Chris.

Exactly the problem we have.Currently lot of python amqp agents for
RabbitMQ which supports AMQP 0-9.[1].

Re: Stratos Python Cartridge Agent

[chris snow <ch...@gmail.com>]

Thanks Gayan!

What errors were you hitting?  The few clients I tried give me the error [1].

It seems some of f the python amqp libraries don't support version 1.0 of AMQP?

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Hi Chris,

Yeah. We looked that qpid messaging as well.For that we need that qpid
proton library .Is n't?
AFAIR it is based on CMake and It requires java also[1].

Also we will share with you the samples we try with the amqp clients.

Re: Stratos Python Cartridge Agent

[chris snow <ch...@gmail.com>]

hi Gayan,

What are the issues that you received from the various AMQP libraries?
Do you have a code repo that I can take a look at to try and replicate
the errors?
Did you investigate qpid [1]?

Many thanks

Chris

Re: Stratos Python Cartridge Agent

[Gayan Gunarathne <ga...@wso2.com>]

Hi Chris,

We try to replace our java cartridge agent with the python as after that we
can remove the java dependency from the cartridge itself.I guess this is
also vital for the Docker support too.

In Apache ActiveMQ site also AMQP support is based on the JMS/AMQP[1]. I
guess message broker implementation will be different from one MQ to other
as some python client which able to connect with RabbitMQ successfully
,still fails with the ActiveMQ.

Thanks,
Gayan

Re: Stratos Python Cartridge Agent

[chris snow <ch...@gmail.com>]

Is the issue because we currently have a mix of JMS/AMQP/Jndi? If we had a
pure AMQP approach would these problems go away?  AFAIK, one of the drivers
for AMQP was interoperability with all languages, rather than jms which is
focused on Java.
