Rechercherichtung

Beginne damit, die JRuby-Fehler in test/drb/drbtest.rb und test/drb/ut_array_drbssl.rb zu reproduzieren, und verfolge dann die gemeldeten Pfade durch lib/drb/drb.rb und lib/drb/ssl.rb. Vergleiche jeden Fehler mit den referenzierten Tests und dem JRuby-Issue, um erwartete Verhaltensunterschiede von Defekten oder Konfigurationsproblemen zu unterscheiden. Die Aufgabe ist abgeschlossen, wenn die Fehler erklärt und entweder behoben, begründet oder mit dokumentierter Begründung von JRuby CI ausgeschlossen wurden.

Vom Indexierungsmodell aus dem Issue-Text verfasst.

Beschreibung

There are a few failures during the test suite on JRuby. We will want to investigate them so we can get JRuby into CI.

Some of these may be expected failures due to behavioral differences on JRuby, like concurrency and GC differences.

  • ArgumentError in test_bug16634: https://github.com/jruby/jruby/issues/8798

  • Connection closed during test_05_break and test_07_break_18. If these are intermittent they may be a thread race or other concurrency-related failure.

  • Several SSL-related tests (basically everything in DRbTests::TestDRbSSLCore) fail with certificate verify failed but I'm not sure if this is a bug or some misconfiguration in JRuby's openssl support. A server in a separate thread crashes as a result and these tests then time out waiting for the server to respond.
