Hi Murtuza,

The code change works, and I passed the patches through our pipeline and everything is green.

Personally I would love this bug fixes to have refactored the function into smaller chunk and made it more readable so that the next time someone need to check out a problem in the same area it is easier. I understand that without a good test coverage it is hard to have confidence while refactoring, but we need to start somewhere.

Are you planning to look into this Murtuza?

​Yes Dave, I am working on another issue, I'll pick up after that.​

 

 

@Hackers

Here is a video that I saw some time ago about refactoring existing code and code complexity that is very interesting

https://www.youtube.com/watch?v=8bZh5LMaSmE

In this video Sandi Metz does the Gilded Rose Kata in a talk in RailsConf 2014, and with it tries to demonstrate that code can be refactored and with that it make the code much more simpler. But the journey is not always simple and the complexity will increase before it get simpler. It is a good example of something that we can try with our code.

Nice!

Hi Dave,

PFA updated patch.

Using your example on the ticket, I added a "character varying (32)" column with NOT NULL to the table. When I then edit the column, and turn off NOT NULL (making no other changes), the SQL generated is:

ALTER TABLE public.test_drop

    ALTER COLUMN col2 TYPE character varying (32) COLLATE pg_catalog."default";

ALTER TABLE public.test_drop

    ALTER COLUMN col2 DROP NOT NULL;

I didn't see that when turning off NOT NULL for col1.

Hello Murtuza/Dave,

Nice splitting of some of the functionality into functions, removing some of the complexity of the initial function. Good job.

I made some changes because the linter was failing and also changed some variable names.

These changes pass our CI and the linter.

Thanks

Joao
