Strange "file missing" error with 3.1.14 release

[ijdickinson]

I have a strange issue that I want to report, even though I don't have a complete characterisation yet.

I've just done a bundle update on one of our Rails apps, and that pulled in rdf 3.1.14. At which point, the app failed to start with this stacktrace (trimmed for brevity) in the log file:

App 17289 output: Error: The application encountered the following error: No such file to load -- rdf/model/literal.rb (LoadError)

If I coerce the version to stay below 3.1.14:

gem 'rdf', '<= 3.1.13'

the app starts up as normal.

What puzzles me is that, as far as I can see, rdf/models/literal.rb has been installed as part of the bundle install, so I don't really understand where the error is arising from.

Would welcome any suggestions, or probes to try!

My guess is that something is failing to require 'rdf', which brings in the auto-load for rdf/model/literal. It will take some work to see what might have changed to affect this dependency chain. You might try adding a require 'rdf' in your app setup.

What explicit requires are done to RDF gems?

i'm seeing reports from users of https://github.com/samvera/hyrax that this is happening during install processes.

i haven't tried to reproduce yet, but can give it a look and see whether i can identify the root cause.

Installing the gem, it looks like a file permission problem; the file is there, but it is 600. Must be some problem in packaging the gem. Best is probably to re-release and yank 3.1.14.

I released 3.1.15 and yanked 3.1.14. A local install verifies the proper permissions (at least for literal.rb). Not sure how permissions might have been messed up.

Let me know if that solves the problem.

Thanks @gkellogg, I'll give that a go tomorrow!

[ijdickinson]

Confirm that the issue we were seeing is fixed by 3.1.15. Thanks for the quick resolution, @gkellogg and @no-reply .
