从 plone 3.3.2 迁移到 plone 4.2.1 失败并出现 PosKeyError。我已经尝试了这篇文章http://plonechix.blogspot.com/2009/12/definitive-guide-to-poskeyerror.html中的食谱。我已经运行了 error_finder 片段，但它没有给我任何异常。我也尝试在调试器中使用对象app.mysite._p_jar[p64(oid)]- 也没有成功，它失败并出现同样的错误。

如何删除损坏的对象或至少获取有关对象的更多信息（例如其类名或位置）？

完整追溯：

POSKeyError('\x00\x00\x00\x00\x00\x0ey=',)

You can use the fsrefs.py to find the bad object.

A very short article on using it is: http://nathanvangheem.com/news/fixing-broken-zodb-object-references

我相信这与我刚刚遇到的问题相同，如果回滚保存点（包括将对象添加到目录）会发生这种情况。我认为这是 ZODB 中的一个错误，但您可以通过解决回滚保存点的任何问题来解决它，在这种情况下，就是将文件和图像迁移到 blob。因此，如果您解决了使这些文件或图像无法成功迁移到 BLOB（或只是删除它们）的问题，那么它应该会成功。
