Re: [pgAdmin4][Patch] Feature #1447 SSH Tunnel - Mailing list pgadmin-hackers

Hi Akshay,

After looking through the patch we found some one letter variable names and this is a regression on what we have been trying to accomplish in the last year.

An objective that we have for pgAdmin source code is to increase the testability of it and make it more readable. If we keep on adding one letter variables and if we continue adding code to already convoluted source files it is going to be very hard to achieve this objective.

Our recommendations for this change are:

- Name the variables with comprehensive names

- Extract functions where we can and try to wrap some tests around them (ex: the javascript disabled functions)

- We really need to find a better pattern than templated Javascript to pass information from the backend to the frontend 

- When changing a piece of code, if we see code that is confusing or that is hard to read, we should refactor instead of adding to the pattern.

Thanks

Victoria & Joao

Hi Hackers

As per suggestion by Dave, I have moved "Advanced" tab at the last for Server dialog. Attached is the modified patch.

For what it is worth, I manually verified that the feature worked, as well as looked through the code.

I'd like to see end-to-end testing for regression sake, but it's hard to so at this moment.

Hey Akshay 

This patch passed our test pipelines.

Did you test the feature and//or review the code and tests? Passing the tests is great, *if* the whole feature is covered (and the nature of this patch will make that quite difficult, maybe impossible to do without external infrastructure and config).

    Agreed, it's been difficult to write test case to test the complete feature.

Hi Hackers 

I have implemented the SSH Tunnel support using https://pypi.org/project/sshtunnel/ python package. Added "SSH Tunnel" Tab in server dialog. This implementation supports user name /password and private/public key combination with Passphrase to crate SSH Tunnel. I have added regression test case to add server using SSH Tunnel options.

The given python package(https://pypi.org/project/sshtunnel/) support Python version 2.7, 3.4+.

It uses Paramiko (Python implementation of SSHv2 protocol) which actually drops support for Python 2.6. So I have added SUPPORT_SSH_TUNNEL parameter in config.py which checks the python version and set the flag accordingly. In case of Python 2.6, 3.0, 3.1, 3.2 and 3.3 control on the "SSH Tunnel" tab of server dialog will be disabled.

Please review it, and if looks good please commit the code.
