Error when uploading RubyGems packages

[deanpcmad]

Description

When trying to upload a RubyGem package to Gitea (main version 1.17.0+dev-629-ge0273bad7), I get a cannot unmarshal !!seq into string error.

gem push --host http://localhost:3000/api/packages/dean/rubygems mygem.gem

Pushing gem to http://localhost:3000/api/packages/dean/rubygems...
yaml: unmarshal errors:
  line 57: cannot unmarshal !!seq into string

Looking at the server logs, it shows this:

2022/05/29 11:58:23 ...rubygems/rubygems.go:24:apiError() [E] [629351cf] yaml: unmarshal errors:
	  line 57: cannot unmarshal !!seq into string
2022/05/29 11:58:23 [629351cf] router: completed POST /api/packages/dean/rubygems/api/v1/gems for 127.0.0.1:39502, 500 Internal Server Error in 13.3ms @ rubygems/rubygems.go:193(rubygems.UploadPackageFile)

When trying to reproduce the error on try.gitea.io, it doesn't show an error but when checking my account, no Gem has been uploaded so I'm not sure if packages are fully enabled on that system?

I've just tried uploading a Docker image and that worked fine

Yeah, packages are disabled for try.gitea.io as far as I know.
For the rest, I don't really have an idea where the problem could be coming from.

Could you upload you gem file and/or project? I added only a basic marshal implementation to get it working. Maybe something is missing.

[deanpcmad]

As it's a private gem, I can't share the contents of it but I did have issues uploading the rails gem

[KN4CK3R]

I have tested rack and rails without problems:

gem push --host http://localhost:3000/api/packages/KN4CK3R/rubygems rails-7.0.3.gem     
Pushing gem to http://localhost:3000/api/packages/KN4CK3R/rubygems...

[deanpcmad]

Hmm, I'll give it another go then. What version are you using there?

[KN4CK3R]

Gitea is current master but there were no changes to the packages registry since 1.17-RC1.

gem -v
3.2.5

[deanpcmad]

Just tried it with another gem of mine, twitchrb and I get a similar error, but different lines:

yaml: unmarshal errors:
  line 29: cannot unmarshal !!seq into string

[KN4CK3R]

Thank you for the new example. Found the error this time and fixed it in #20470.

[deanpcmad]

Just to confirm this is now fixed for a few Rubygems I've tested. Thanks!
