在Plone5.1升级到Plone5.2过程中可能的坑

在Plone5.1升级到Plone5.2过程中可能的坑

本文收集了在Plone5.1升级到Plone5.2过程中可能遇到的一系列坑以及解决办法.
1、不能导入IPossibleSite错误
错误产生的条件:
当你有定制的Dextertity内容类型,并且,你的代码中启用five.grok来代替ZCML来书写配置信息。
产生原因:
five.grok 依存的 IPossibleSite接口由原来zope.location包迁移到了zope.component包

3.7.1 (2009-11-18)

    Move the IPossibleSite and ISite interfaces to zope.component as they are dealing with zope.component’s concept of a site, but not with location.


src/five/grok/components.py

from zope.annotation.interfaces import IAttributeAnnotatable
from zope.location.interfaces import IPossibleSite
from zope import interface

解决办法:
编辑src/five/grok/components.py
将这行代码

from zope.location.interfaces import IPossibleSite

更改为:

from zope.component.interfaces import IPossibleSite


2、配置冲突错误
在Zope-4.1.1和zope.browserresource两个包中同时定义了 FileETag adapter,导致zcml配置冲突。
解决办法:取消Zope-4.1.1中重复加载的适配器定义。
编辑配置文件:

vi /home/demo/.buildout/eggs/Zope-4.1.1-py2.7.egg/Products/Five/browser/configure.zcml

注释adapter定义,如下代码9~10行所示:

<configure xmlns="http://namespaces.zope.org/zope"
           xmlns:browser="http://namespaces.zope.org/browser">

  <interface
      interface="zope.browsermenu.interfaces.IMenuItemType"
      />

  <include package="OFS" file="absoluteurl.zcml"/>
<!-- adam
  <adapter factory="zope.browserresource.file.FileETag" /> -->

  <browser:view
      for="OFS.interfaces.IObjectManager"
      name="+"
      class=".adding.ContentAdding"
      permission="zope2.ViewManagementScreens"
      >

    <browser:page name="index.html"  template="adding.pt" />

  </browser:view>


3、要求Product.archetype依存性错误
错误产生条件:
加载三方包dexterity.membrane时出现。
错误产生原因:
dexterity.membrane依存于Products.membrane,而Products.membrane目前最新版4.0依然依存于Product.archetype,但Plone5.2.0后已经完全drop掉
Product.archetype和Product.ATContenttype。

  File "/home/plone/workspace/Plone5sites/sites/src/Products.membrane/Products/membrane/at/interfaces.py", line 11, in <module>
    from Products.Archetypes.interfaces import IBaseObject
ImportError: No module named Archetypes.interfaces

生活还要继续,我们不能退回到原始社会···
解决办法:
新建Products.membrane 5.0分支,drop 掉对Product.archetype的依存,并适当更新代码,使其完全支持Plone5.2.x。

4、Plone.PlonePAS导入错误:

  File "/home/plone/workspace/Plone5sites/sites/src/Products.membrane/Products/membrane/setuphandlers.py", line 5, in <module>
    from Products.PlonePAS.Extensions.Install import activatePluginInterfaces
zope.configuration.xmlconfig.ZopeXMLConfigurationError: File "/home/plone/workspace/Plone5sites/sites/src/Products.membrane/Products/membrane/exportimport/configure.zcml", line 17.2
    File "/home/plone/workspace/Plone5sites/sites/parts/instance/etc/site.zcml", line 16.2-16.23
    File "/home/plone/.buildout/eggs/Products.CMFPlone-5.2.0-py2.7.egg/Products/CMFPlone/configure.zcml", line 110.2-114.8
    File "/home/plone/workspace/Plone5sites/sites/src/dexterity.membrane/dexterity/membrane/configure.zcml", line 9.2-9.37
    File "/home/plone/workspace/Plone5sites/sites/src/Products.membrane/Products/membrane/configure.zcml", line 12.2-12.37
    ImportError: No module named Extensions.Install

错误原因:

5.0.1 (2015-03-21)

    Add a integrated test setup with codeanalysis and travis. For this moved Products folder to a src folder in order to follow the package structure expected by buildout.plonetest’s qa.cfg. [jensens]
    Make patching of LDAPMultiPlugin explizit. Code using those must call Products.PlonePAS.ldapmp.patch_ldapmp with no parameters in order to activate the patches. [jensens]
    Removed (optional) Archetypes Storage (used in past with CMFMember, which itself was long time ago superseeded by Membrane). Probably dead code. If theres someone out there needing it in Plone 5 please copy the code from git/Plone4 in your addon/project. [jensens]
    Moved Extensions/Install.py functions to setuphandlers, kept BBB import for activatePluginInterfaces since this is imported by borg.localrole. [jensens]

错误处理:
使用 Products.membrane 5.0 branch
