What did you expect to see?

For it to work.

What did you see instead?

Did not work and failed with error message.

[ibrasho]

You have github.com/sirupsen/logrus and github.com/Sirupsen/logrus in your dependency graph (note the difference in cases) since some of your dependencies still import github.com/Sirupsen/logrus.

We had an approach to this as described in https://github.com/sirupsen/logrus/issues/553#issuecomment-307486868 but no one got to implement it yet. 😩

[Skarlso]

Well my dependencies have that. Damn that's not nice. :-( is there any kind of workaround for that?

[ibrasho]

I'm afraid that you can't solve this without updating dependencies at the moment (until we handle this case in dep).

[Skarlso]

But it's a transient dependency. I can't fix it. :( I don't depend on it. Some of my dependencies depend on it. How can I fix THAT? :)

[sdboyer]

@Skarlso yeah, until we fix it and fold cases together correctly, the only recourse you have is asking one of the projects you depend on to make the fix. Or, forking one and fixing it yourself, then pointing the import path to your fork with a source: directive in Gopkg.toml.

I'd recommend preferring lower case to upper, here.

[Skarlso]

Oh I see. Thanks @sdboyer. :-)

[nathany]

Would case folding require changes to the go tool or compiler?

(Assuming import paths remained mixed case).

[ibrasho]

@sdboyer's proposed solution doesn't require any changes to go toolchain or compiler. We can handle this within dep (more specifically, within gps).

[Skarlso]

So, Glide solves this with a --force flag, which detects if there was a change in a repo path, and if yes, it overrides the previous one and uses that. It's dirty, but it does work. :) For brevity, and because I dislike slack (:P) I'm going to put the proposed solution here as well.

1. the system that deduces repo/project roots from import paths needs to be expanded to return some kind of informational structure of case sensitivity for different elements of the paths
2. the system that manages repositories on disk needs to learn how to read those case sensitivity info structures, and we'll need a new trie implementation that works with them
3. the solver itself will need to stop using simple map[string]<...> types, and use a custom map that, again, works with these case sensitivity info structures
4. at least, this is what a "proper" solution looks like
5. but the risk and complexity of that is considerable, so we'll likely have to settle for some harm reductive approaches in the meantime
6. but yeah, i need to strategize a bit so that i can break this up into issues

[ibrasho]

Even glide has a similar issue. You won't be able to install the dependencies for the code below if you are on a case-insensitive file system. And the real issue for me is that version selection was done twice, and therefore you could have 2 versions of the same dependency.

package glidetest

import (
    l1 "github.com/Sirupsen/logrus"
    l2 "github.com/sirupsen/logrus"
)

func main() {
    _ = l1.New()
    _ = l2.New()
}

[Skarlso]

Ahhh totally forgot that that doesn't work. Right you are @ibrasho.

[rfay]

After #813 I made a naive attempt to resolve this by changing references from Sirupsen to sirupsen, but that turned out to be way too naive, since there are dependencies in the vendor directory that import Sirupsen/logrus, and that haven't been updated to sirupsen. So IMO this definitely requires a workaround of some type in dep. Who ever thought it would be OK to have a case-insensitive filesystem anyway!

[davidovich]

This is also breaking our usage of dep in a Windows environment. Should dep be aware that it is running in a case-insensitive filesystem and in that case use the existing (the first one created wins) git repo?

[sdboyer]

@davidovich we may have to resort to something like that in order to stop the bleeding, but it's a pretty fundamental violation of dep's rules to do that. so, yeah..._temporary_. god, i hope 😨

[tejasmanohar]

Is there an quick way to tell what transitive dep is importing Sirupsen/logrus (with a capital S)?

[sdboyer]

@tejasmanohar not currently, but #1079 will make it trivial.

[kumarsiva07]

Is there anyway to overcome this?

[sdboyer]

@kumarsiva07 right now, it takes a lot of manual work. once #1079 is in, dep _should_ find a solution for you, if one exists.

given that you're just trying to get over the initial hump that is dep init, you might try compiling dep from that PR and running dep init for your case. at minimum, you should get a more useful error, and we could use some real-world testing of this!

[therealplato]

I'm still encountering this on OSX with recent dep (1dc2d8b6)

[sdboyer]

@therealplato yeah I saw your note in slack - I'm honestly confused about how you arrived there 😢

[therealplato]

i arrived there by trying to use a top-level vendor folder with leftover cruft in subfolders from old vendoring @sdboyer

@spenczar provided a workaround (at least for me on OSX)

• delete all folders with unwanted capitalization
• commit that deletion
• dep ensure

[pires]

One option could be to allow exclusion of transitive dependencies, no?

[pires]

Actually, it's already possible, it seems!

ignored = ["github.com/Sirupsen/logrus"]

[[override]]
  name = "github.com/sirupsen/logrus"
  version = "^1.0.5"

[sdboyer]

@therealplato that also does not make sense. dep prepares its vendor folder in a separate dir, then moves it into place.

im honestly not sure if an ignore like that would have the desired effect. it...might, but it also might have some weird side effects, as I can't recall how we deal with case normalization in ignores.

[pires]

Well, at least the vendor directory seems clean.

$ find . -name logrus
./vendor/github.com/sirupsen/logrus
