{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Finalizer tries to dispose objects, that belong to previous Runtime \"generation\"","articleBody":"### Environment\r\n\r\n- Pythonnet version: master\r\n- Python version: any\r\n- Operating System: any\r\n\r\n### Details\r\n\r\n1. Initialize `Runtime`\r\n2. Create a few `PyObject`s, keep them somewhere\r\n3. Shutdown `Runtime`\r\n4. Initialize `Runtime` the second time\r\n5. Clear all alive reference to objects from step 2.\r\n6. Call `GC.Collect` and `WaitForPendingFinalizers`\r\n\r\n**Expected**: `XDecref` should never be called on the handles in `PyObject`s from step 2.\r\n**Actual**: `XDecref` is called on the handles in `PyObject`s from step 2.\r\n\r\nI saw this happen even to .NET types reflected to Python like `System.MulticastDelegate`. Will soon open a PR with repro.","author":{"url":"https://github.com/lostmsu","@type":"Person","name":"lostmsu"},"datePublished":"2020-03-03T02:08:09.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1073/pythonnet/issues/1073"}| route-pattern | /_view_fragments/issues/show/:user_id/:repository/:id/issue_layout(.:format) |
