External Evaluation for ISO 8583 PoC - Milestone 1

External Evaluation ISO 8583 PoC

In general, most of the delivery is provided. I encountered some errors while building parts of the solution, so I expect these issues to be resolved before marking the delivery as Accepted. The issues can be resolved through code or documentation.

1. Installing interface dependancies was successful with some warnings.

warnings are displayed due to version mismatches in the dependencies, unfortunately, some of the packages I am depending are not actively maintained, so it won't be possible to fix the warnings.

3. Starting the interface was not possible initially due to the following legacy issue:
   Removing the -openssl-legacy-provider solved the problem. Please resolve this issue.

thank you for the tip, I fixed the issue.

4. Running the makefile fails with the following output:

Issue is with your local postgres server. Before I can address it I need to know if you are running postgres locally and if default values for the DB exist in your local setup.

6. Running the docker container locally gives the following error:

Fixed and pushed

Could you publish your images to dockerhub, so we can download the pre-build images rather than building them locally?

Sure, here it is deployed

7. The oracle tests were failing tho.

Same issue as 4

8. Running the Oracle fails with similar error as the Makefile.

Same issue as 4

9. Consider hosting the solution online for the second delivery. It makes everything much easier to test and validate the functionality without running everything locally.

I think it's a good idea, will definitely consider it. Or at least a docker-compose configuration with images deployed to DockerHub

Let's switch the discussion here @stojanov-igor.

Since you didn't have postgres server running locally, you encountered the above issues with the oracle. Let me know how it goes after you install postgres

thank you for your review

I was able to install Postgres. However, I still have the same issue:

    Finished release [optimized] target(s) in 0.12s

Let me know if I am missing something...

are you sure postgres server is running? maybe it exposes a different port? or default database is not postgres? try setting DB variables for the oracle explicitly, with the arguments mentioned in the README

can you paste values of the following commands:

pg_isready

pg_ctl status

if it doesn't show /tmp:5432 - accepting connections or sth similar, you are not properly running postgres

[dastansam]

in any case, Connection refused error is usually related to improperly configured postgres server. make sure it's running and default user postgres and db postgres are there. If it's not there and you are using other users, pass your DB configuration explicitly.

hey @stojanov-igor,

I think I solved your issue. I added a docker-compose file with Postgres Docker image, and now you don't need to have postgres installed to run the oracle.

Just docker-compose up and it should be running.

[stojanov-igor]

Hi @dastansam,

Thank you for the prompt reply. The docker image worked for me.

I have updated the status of the delivery to Accepted. There are still some nice to have things that have to be implemented in the future, but I think you have fulfilled the requirements for Milestone 1.

The team at Web3 Foundation will also do their own evaluation, so I wish you good luck.

@stojanov-igor thank you for the external evaluation. It is accepted. I'll forward your KSM payment. Great job!
