Warnings from mxODBC in 2.8.5

Hi All,

I get the following warnings from mxODBC on Zope 2.8.5:

lib/python/OFS/Application.py:788:
DeprecationWarning: __init__.py of Products.mxODBCZopeDA has a long
deprecated '__ac_permissions__' attribute. '__ac_permissions__' will be
ignored by install_product in Zope 2.10. Please use registerClass instead.
DeprecationWarning)
lib/python/OFS/Application.py:803:
DeprecationWarning: __init__.py of Products.mxODBCZopeDA has a long
deprecated 'meta_types' attribute. 'meta_types' will be ignored by
install_product in Zope 2.10. Please use registerClass instead.
DeprecationWarning)
lib/python/OFS/Application.py:820:
DeprecationWarning: __init__.py of Products.mxODBCZopeDA has a long
deprecated 'methods' attribute. 'methods' will be ignored by install_product
in Zope 2.10. Please use registerClass instead.
DeprecationWarning)

Have other people seen this?
I tried adding a warning filter but it didn't have any effect. My only
guess is becuase mxODBC ships only as .pyc files :-S

Anyway, I guess this is mainly aimed at the eGenix people: is there a
version of mxODBC available which has these problems fixed?

cheers,

Chris

The warning filter should work for any Python code which
issues these warnings, regardless of where and how it is
defined. However, you'd have to register
the filter early during Zope startup in order for it
to be active by the time OFS.Application.py is imported.

No. The reason is that the mxODBC Zope DA supports many old
Zope versions (starting with Zope 2.3).

Our next version will only be available for Zope 2.7 onwards
and will remove much of the old-style interface logic which
we still have to keep around for backwards compatibility
reasons.

Hi Chris,

are you using Zope 2.8.5 or Zope 2.9.0 or are they the same thing?

I'm using the warning filter stuff that zope.conf provides, it works for
all other products ,just not mxODBC. I wonder why?

2.8.5.

I find the fact that you ask if 2.8.5 and 2.9.0 are the same thing quite
scary...

You shouldn't worry too much! I'd just installed the FreeBSD port for
2.9.0 which was actually 2.8.5!

2.9.0 is *not* 2.8.5. If you install ports from third parties who
package the wrong thing that's an unrelated problem the packager
needs to be made aware of.

Haha... okay, that just makes me even more scared of FreeBSD...

Well, given that in Zope 2.9.0 it also doesn't catch
the following warning that you get on startup:

/home/lemburg/zope/Zope-2.9.0/lib/python/App/ImageFile.py:21:
DeprecationWarning: Using OFS.content_types is deprecated (will be
removed in Zope 2.11). Instead use zope.app.contenttypes.
from OFS.content_types import guess_content_type

this doesn't sound surprising. Perhaps there's a bug
in the Zope filter code ?!

Sorry, but we don't have an ETA yet.

Oh, it shouldn't! FreeBSD's ports are excellent and really easy to use. It
was my mistake as I should have read the package information. I have
reported the mislabelling to the maintainer.

The current breakneck pace of Zope releases doesn't make it easy for
companies like us providing Zope add-ons. The last couple of releases have
all had minor changes in the architecture which have required changes to
the mxODBCZopeDA for compatability. We are still waiting for the Windows
binary version of Zope 2.9 before we release anything for it.

FWIW this also effects ZpsycopgDA (at least using 1.1.21)

Did you put in a specific warn filter for this?

Well, the above was a bug that I think has already been fixed...

I haven't seen it though, as it's only in 2.9 and we're using 2.8

Yes, one that's supposed to catch exceptions.DeprecationWarning
(basically, I just uncommented the example in the zope.conf
file).
