Cannot clone public repository over HTTP anonymously.
Closed, ResolvedPublic


Since the new management UI (T10922: Upgrading: New Repository UI, APIs, and URI management), we can no longer access our anonymous access repositories over HTTP.

Reproduction steps:

  • For a Phabricator-hosted repository, click manage repository
  • Go to policies
  • Set visible to "Public (no login required)"
  • Attempt to clone the repository over HTTP
    • git clone http://phabricator.internal/diffusion/CALLSIGN/callsign.git

Expected result:

  • Git clone is successful

Actual result:

The only way I have been able to get anonymous HTTP cloning to work is by enabling diffusion.allow-http-auth first, however the docs at state I should be able to leave this option disabled for anonymous access (specifically the first sentence under "Configuring HTTP which says: "If you plan to serve repositories over authenticated HTTP, you need to set diffusion.allow-http-auth in Config. If you don't plan to serve repositories over HTTP (or plan to use only anonymous HTTP) you can leave this setting disabled.").

Leaving this diffusion.allow-http-auth enabled is not ideal for us because it allows all of our repositories to be cloned over HTTP, not just the ones that we have given anonymous access to. This also causes issues to us that are similarly described in T10517: Make Harbormaster build variables extensible where the default {repository.uri} becomes the HTTP URI instead of the git URI which breaks how we use Harbormaster today.

debugging troubleshooting

I'm not sure it's a bug. The error message was surprising; HTTP/1.0 500 Error 1: sudo: a password is required. I see a matching error message in Q261. The solution there seems to be allowing the webserver process owner to have sudo rights. I now found there are docs on the subject diffusion_hosting#configuring-sudo.

We'll verify the config is setup correctly.

Sorry to leave this hanging, but the issue was with our server configuration. We did not have the correct sudo rights confgured
