dvc import broken authentication #7898

wdixon · 2022-06-14T16:12:40Z

We seem to no longer be able to import a remote dvc resources from a repository that requires authentication. This worked at some point prior to 2.10. This worked previously.

The output of the import is as follows:

The above exception was the direct cause of the following exception:

There was some previous commit appears to fix a similar issue, which was part of the 2.11 release:
issue #7670
however, updating to 2.11 did not fix the issue.

I reverted to version 2.9.5 and can now perform the dvc import of a remote resource as expected.

I would also point out that dvc update was also not working - failing for the same authentication issue.

dtrifiro · 2022-06-16T08:51:29Z

Hey @wdixon, would you mind providing a full traceback? Thanks

wdixon · 2022-06-16T10:33:14Z

I don't have a configuration that I can run from the same system.... but here is the same issue run from a windows system (the traceback doesn't appear to be as verbose - but the line numbers seem to match the traceback from the earlier linux system). Does this have the info you need?

Hi @wdixon, yes. Thank you.

This is a known issue (e.g. see #7670, #6586)

The problem is that since 2.9.5, scmrepo was bumped and in 0.0.11 the dulwich git backend for clone was implemented (favoring that over GitPython). Note that GitPython uses CLI git under the hood (which is not always available, hence the move to dulwich).

I'm assuming the http auth credentials are being passed to git using a credential helper defined in your git configuration.

Clone breaks because dulwich has no way of providing credentials for authentication since it doesn't support credential helpers (yet).

If you wish to use dvc > 2.9.5 the workaround for http auth is providing username/password in the URL you wish to import:

dvc import https://username:password@github.build.company.com/auto-inspection/BIT_Tool_Artifacts.git pose/S1FV_PS_A_20220606-092610-0558-0.0003.hdf5

The good news is that there's an open PR (jelmer/dulwich#976) which adds support for credential helpers. If you want to test it out, you can try installing it:

pip install git+https://github.com/dtrifiro/dulwich.git@feature/credential-helper

Any feedback would be appreciated!

wdixon · 2022-06-16T11:44:35Z

Our backend enterprise git is configured to disallow username:password in the URL; however, it does accept tokens in the URL.... But unfortunately this doesn't seem to work work either - though this would be a more common way to pass credentials that including the password in the clear....

Using the token in the URL produces a different exception (see below).

The token does comply with the RFC.... It is simply the case where no password is provided, only the user (as the token)

Directly from the RFC text:

        //<user>:<password>@<host>:<port>/<url-path>

password
        An optional password. If present, it follows the user
        name separated from it by a colon.

When authenticating using basic auth and only providing username (no password) the default value of `None` was cast to string, resulting in an attempt to authenticate using `<username>:None` instead of providing an empty password. This broke authentication when providing an auth token as username. See iterative/dvc#7898 (comment)

dtrifiro · 2022-06-20T18:07:38Z

I'm sorry, you're right. That is a bug in dulwich. Opened up a PR upstream. See jelmer/dulwich#980

dtrifiro · 2022-06-21T11:15:48Z

Recap:

For broken imports related to the change from gitpython backend to dulwich: we're waiting for git credentials support in dulwich (add support for git credential helpers jelmer/dulwich#976)
For broken https://token@host... authentication: it has been merged in dulwich, so we're waiting a release and scmrepo version bump

dtrifiro · 2022-07-11T18:13:47Z

@wdixon dulwich has merged the basic auth fix, so by using dulwich >= 0.20.44 you should be able to use dvc import with the token@host syntax. Still waiting on proper git credentials support though

d-miketa · 2022-07-27T21:49:21Z

@dtrifiro FWIW I tried installing dulwich from your feature branch using

pip install git+https://github.com/dtrifiro/dulwich.git@feature/credential-helper

and I'm unfortunately still running into the same issue:

❯ dvc pull data/dataset.dvc

Downgrading to 2.9 fixes the issue. I'm on macOS.

dtrifiro · 2022-07-28T10:23:51Z

@d-miketa thanks! Could you post a full traceback using dvc pull -v?

d-miketa · 2022-07-28T16:48:26Z

I got rid of the import but here's a similar issue when trying to do dvc exp list origin; also crops up when pushing an experiment:
