Re: [Dev] [GSOC][CEP][DEV] Python API for Siddhi CEP

Hi Madhawa, Great progress so far. As per our offline discussion, for the above callback issue, please go ahead with the workaround you found on [1]. Since it only affects Python 3.4 and above, use a version check to decide whether to use the workaround or not. Once you get all the test cases to

Hi Madhawa, I went through your impl and it works great. Try to improve the test cases and documentation (README.md on git) when you get a time. Furthermore, I have added Event simulator REST API endpoints to the doc that you shared earlier. After getting debugger to work, try to wrap event

Hi, I started working on the native wrapper. So far, have the very basic functionality working for Siddhi 3.1 and Siddhi 4.0. I am maintaining my code at the repo [1]. Next step is getting the Siddhi debugger working. I will let you know when it is done. [1] -

Sure we'll look into that. As the immediate next step can you make finish the work on native Siddhi working with python. Make sure Siddhi debugger also works. Regards Suho On Fri, May 19, 2017 at 11:45 AM, Madhawa Vidanapathirana < madhawavidanapathir...@gmail.com> wrote: > Hi, > > I have

Re: [Dev] [GSOC][CEP][DEV] Python API for Siddhi CEP

Hi, I will look into REST side also then. Already found good APIs to work with Native Calls and SOAP. I am also trying to come up with a list of classes of Siddhi Java Library that should be exposed via Python API. I don't think its required to wrap the internal classes since their

Re: [Dev] [GSOC][CEP][DEV] Python API for Siddhi CEP

Siddhi 3.x is compatible with DAS 3.1, and Siddhi 4.x is compatible with DAS 4.0 which we are still working on. Siddhi APIs does not drastically change from 3.x to 4.x, DAS 3.1 uses SOAP and DAS 4.0 uses HTTP/REST APIs So apart from native APIs, if you have figured out a way to use REST and SOAP

Hi, Need bit more clarity on what versions of products we should build on. Are we developing on DAS 3.1 (as mentioned in beginning of mail thread) or 4.0 (mentioned in previous mail) ? Also, what version of WSO2 CEP? According to my understanding so far, we are developing on Siddhi Java Library

Hi Suho, Got the prototype working with Python 3 as well. Refer the link below for sources. https://github.com/madhawav/CEP-Python-Wraps/tree/master/Pyjnius_Prototype_Wrap_Python2_3 This version works with both Python 2.7 and 3.x. (Tested on 2.7 and 3.5). Uses native calls via Pyjnius API.

Hi Suho, Going ahead with the proposal, few questions crossed my mind. 1. You mentioned previously that WSO2 DAS should also be supported. What sort of interactions are expected with WSO2 DAS? 1. Should publishing events to WSO2 DAS from Python Siddhi API supported? 2. Should
