Add home directory to config file search paths by System-Glitch · Pull Request #1325 · golangci/golangci-lint

System-Glitch · 2020-08-21T14:48:55Z

Guidance required: tests don't pass if you have a configuration file in your home directory. This is because some tests check that config is not found. I need assistance on how to update tests properly.

So, dumb question, but I must ask it: have you test it on your env? Since we cannot write the unit test for this. And I cannot test it on my laptop, I don't have external adds or usb sticks

System-Glitch · 2020-08-21T15:00:27Z

I have tested it but have not written automated tests for it.

From another drive (/mnt/6C161AE6161AB156), I ran it and got

$ ./golangci-lint run -v
INFO [config_reader] Config search paths: [./ /mnt/6C161AE6161AB156 /mnt / /home/jeremy] 
INFO [config_reader] Used config file ../../home/jeremy/.golangci.yml

With v1.30.0:

$ golangci-lint run -v

/home/jeremy/.golanci.yml:

You can notice the additional linters I enabled are correctly enabled.

Cool, thanks

System-Glitch · 2020-08-21T15:07:17Z

So, we leave it like that and write no tests?

bombsimon · 2020-08-21T15:12:17Z

Another question just to be sure since I haven't dug into the code, is the search order like this now so /home doesn't come after /mnt/path/go but before /mnt/path? Because I think that could be breaking for some users.

Given code in /mnt/path/go

/mnt/path/go
/mnt/path
/mnt
/
/home

SVilgelm · 2020-08-21T15:12:26Z

We can write the test, but it will require some refactoring. viper.SetConfigName(".golangci") must be changed and the ".golangci" must be moved to a variable, so it's not a constant. Then unit tests can change that variable and generate the config files and put them to the all possible folders and test that the expected file is used.

SVilgelm · 2020-08-21T15:14:37Z

it will work in this order:

/mnt/path/go
/mnt/path
/mnt
/
/home

the /home is the latest folder

System-Glitch · 2020-08-21T15:15:56Z

@bombsimon The home directory is added last, so it should be checked last.
See my comment above:

INFO [config_reader] Config search paths: [./ /mnt/6C161AE6161AB156 /mnt / /home/jeremy]

However, there is a possibility for duplicate paths (effectively checking the same path twice). I can add a check to prevent this if needed.

Proof:

$ ./golangci-lint run -v
INFO [config_reader] Config search paths: [./ /home/jeremy/Projects/go/randomproject /home/jeremy/Projects/go /home/jeremy/Projects /home/jeremy /home / /home/jeremy]

@SVilgelm I am still a bit lost on how I could write those tests. Maybe it can be merged and tests added later by the core team?

System-Glitch · 2020-08-21T15:24:48Z

Duplicate paths fixed:

$ ./golangci-lint run -v
INFO [config_reader] Config search paths: [./ /home/jeremy/Projects/go/randomproject /home/jeremy/Projects/go /home/jeremy/Projects /home/jeremy /home /]

SVilgelm

Looks good to me. Thank you

 	}
 }

+func sliceContains(slice []string, value string) bool {


I can't find where this function is used.

https://github.com/golangci/golangci-lint/pull/1325/files/b5ca52de4a96d08869900d387607b8244d5e9986#diff-e85ca4ec86b591a1db43740ce03c8773R187

I think it would be better to move to slice utils or so, so we can reuse it later

oops, my bad :(

it's needed to avoid duplications in the list of folders

Should I create a new package pkg/sliceutil and put it there?

yeah, it would be better if you move it to pkg/sliceutil
