This is an auto-filed bug because dev-ruby/rack-cache fails tests. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info. NOTE: If you need further logs, feel free to ask.
Created attachment 640290 [details] build.log build log and emerge --info
To save others the effort of reading the log to see if they have the same issue, the relevant segment of the build log is: ------ 1) Error: Rack::Cache::Context#test_0078_passes if there was a metastore exception: NameError: uninitialized constant Timeout test/context_test.rb:981:in `block (3 levels) in <top (required)>' test/test_helper.rb:170:in `request' test/test_helper.rb:177:in `get' test/context_test.rb:980:in `block (2 levels) in <top (required)>' 296 runs, 1408 assertions, 0 failures, 1 errors, 0 skips Focus on failing tests: mtest test/context_test.rb:970 ------ For me, this is rack-cache-1.12.0, and this failure only occurs for ruby26, passing for ruby25.
