-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Zope Developers, I've asked about this on the zope@ list, without getting any replies. Talking about it in #zope, I decided that maybe I will have to ask here from another point of view. As I was testing moving a big, old application to Zope 2.13, I was greeted with the following error: (...) from Products.ZCatalog.CatalogPathAwareness import CatalogPathAware ImportError: cannot import name CatalogPathAware Looking at the code informs me that CatalogPathAwareness is deprecated. I since noticed that apart from the depreciation, also the "emtpy" class CatalogPathAware(CatalogAware) has been removed from CatalogPathAwareness.py. The depreciation message points to zope.lifecycleevent. Looking at http://pypi.python.org/pypi/zope.lifecycleevent I see some examples about calling those notify() events, but nothing that would tell me how to replace CatalogPathAware with this stuff. Googling for [CatalogPathAware zope.lifecycleevent] does not give me anything besides some SVN commit messages. So, anybody have some examples of doing this, please? Specifically an example for replacing CatalogPathAware with zope.lifecycleevent. Since this is what the depreciation message talks about, it's been done many times over and should be well documented, right? I also hope that developers are aware that this change involves changing the base classes that classes in production systems out there are based on. I assume this kind of thing has been discussed and the decision has been taken on judging backwards compatibility vs. the benefits of doing this? (Personally I don't know those benefits, but I'm open to learn. I'm also open to help if there is any work involved, I'm planning to give back more to the zope community in the near future.) Thank you very much, Regards, Sascha -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (Darwin) iD8DBQFNqBeEpYOq9ODq/IoRAr8UAKCmziFbjoJ/rD+jOqycMnzyCjrPngCfQFoP UOqcNboJ0XMuX3z9sBM6z2o= =3aWj -----END PGP SIGNATURE-----
