Question

我正在进行blob迁移到3.2.1站点，我得到“RuntimeError：在调用Python对象错误时超出了最大递归深度。”在@@ blob-file-migration期间的某个文件上。

我发现了这个http://svn.eionet.europa.eu/projects/Zope/ticket/4190，看起来他们通过创建自定义迁移器解决了图像问题。

有任何线索吗？跟踪回溯。

Answer 1

当使用Products.contentmigration从Plone 3.x迁移到Plone 4.x时，我得到了同样的错误。似乎plone.app.blob迁移中存在一个错误。我们进行了此自定义迁移以绕过递归错误：http://svn.eionet.europa.eu/projects/Zope/browser/trunk/Products.EEAPloneAdmin/trunk/Products/EEAPloneAdmin/Extensions/ImageFS2Image.py?rev=29656

问题在于.schemaextender版本（2.1.1）。向下固定到1.6.0解决了这个问题。这也解决了3.3.5站点上的随机KeyError问题。我认为这与#12051和#11396有关。看起来这些是较新版本的at.schemaextender的常见问题，但在包的自述文件中没有Plone 3.x的信息。
