Probably related commit: FIX: Use dualstack S3 endpoint for direct uploads (#29611) · discourse/discourse@0568d36 · GitHub

I use S3 object storage upload to DO Spaces. The issue is probably with this.

Configure an S3 compatible object storage provider for uploads

Configuration

In order to store Discourse static assets in your Object Storage add this configuration on your app.yml under the hooks section:
  after_assets_precompile:
    - exec:
        cd: $home
        cmd:
          - sudo -E -u discourse bundle exec rake s3:upload_assets
          - sudo -E -u discourse bundle exec rake s3:expire_missing_assets

Thanks

I commented out these lines which makes the rebuild run successfully but the site stuck on splash I think because cannot load assets. Safe mode same…

  after_assets_precompile:
    - exec:
        cd: $home
        cmd:
          - sudo -E -u discourse bundle exec rake s3:upload_assets
          - sudo -E -u discourse bundle exec rake s3:expire_missing_assets

Any idea? I know it’s a bad timing…

Hey Don, we’ll have a look. Thanks for reporting.

Thanks Natalie

For quick fix I’ve rebuild with cc01555fce59e116b76c912b4c5195e111a652b2 version, which is one commit behind this FIX: Use dualstack S3 endpoint for direct uploads (#29611) · discourse/discourse@0568d36 · GitHub

My rebuild with a Digital Ocean Spaces S3 setup started failing with this error:

Maybe S3_REGION should be cleared if an endpoint is set here?

EDIT: Oops. I thought I’d searched. Sorry Falco.

Strangely, that gives me this error:

Gem::LoadError: can't activate webrick-1.9.0, already activated webrick-1.8.2 (Gem::LoadError)

which I’d just seen on an instance I was using to run an import, which I “fixed” by upgrading.

I guess I just can’t upgrade this server right now.

Don · November 7, 2024, 7:48pm

I am not sure but maybe worth a try. I did a rebuild succesfully before do this.

And just after this try to rebuild with pick the commit. Second time run the rebuild successfully.

Falco · November 7, 2024, 8:14pm

@martin usually what we do here is providing a GlobalSetting to disable the behavior that people running incompatible S3 clones can then opt-in to make it work.

IMO, the current behavior should stay as the default, but provide toggles to increase compatibility.

See prior art in DISCOURSE_S3_HTTP_CONTINUE_TIMEOUT, DISCOURSE_S3_INSTALL_CORS_RULE, etc.

martin · November 8, 2024, 12:13am

Ah sorry my bad here everyone, these S3 clones always slip my mind. I actually had to fix this custom endpoint issue with Minio yesterday. I think the fix here can just to be never use dualstack if DISCOURSE_S3_ENDPOINT has been set since they are incompatible, and everyone here is seemingly using that.

martin · November 8, 2024, 1:13am

I merged a fix for this now:

https://github.com/discourse/discourse/pull/29654

pfaffman · November 8, 2024, 4:03pm

Thanks for the quick fix! I’m back in business.

Thanks for the lucid explanation, Rafael!

That’s because there’s a lot of stuff to keep in mind! And the spec tests, I think, would require those annoying stub_requests which I know I hate writing.

FWIW, that sounds right to me. And you could probably write tests for that that didnt’ require stubs for stub_requests.

merefield · November 13, 2024, 11:29am

I don’t think this should be marked as fixed .

This change has very likely caused a break to backups on several instances (with others not knowing that their instances aren’t backing up yet presumably).

That suggests to me the specs are not broad enough to capture all the real use cases and changes are passing that shouldn’t have?

pfaffman · November 14, 2024, 5:01pm

It sounds to me like it is fixed just for sites that have use_s3 turned on but not those that are using S3 only for backups.

Though it is again possible to rebuild, it’s just that S3 backups are broken.
