3 PyWin problems with Zope 2.7.6.B2

[Martin Gfeller]

As you requested, I tested Zope 2.7.6.B2 with Quantax on Windows (XP Prof SP2).

During startup, I get the following log:

2005-04-24T15:41:43 DEBUG(-200) FileStorage create storage C:\Program Files\Quantax/var/Data.fs

When I upgrade the Pytonwin Installation to release 204 and changed sitecustomize.py to point to it (see Collector 1711),

I got the following error during statup:

 C:\Program Files\Quantax\etc>"C:\Program Files\Zope\bin\python.exe" -O "C:\Program Files\Zope\lib\python\Zope\Startup\run.py" -C "C:\Program Files\Quantax\etc\zope.conf"

    hevent = win32event.CreateEvent(sa, 0, 0, event_name)
 TypeError: The object is not a PySECURITY_ATTRIBUTES object

After it started with the new build, it issued a complaint as attached when trying to launch Excel as a COM object.

All this worked fine with 2.7.5. So I conclude that something with the installation of PyWin is wrong.

Best regards, Martin

Experienced a similar problem (but with Zope 2.7.6-final on Win2K):

This is the windows binary release, plain install without extra products, i did not change the included python interpreter. Zope is not installed as a service and started by INSTANCEFOLDER/bin/runzope.bat

The .bmp shows the bizarre message you get if an older installation of pywin32 gets picked up. It looks like Mark Hammond's patches to improve Zope operations on Windows made it into 2.7.6, but not his patches to build the Zope Windows installer with the correct corresponding build (204) of pywin32. If so, it's a problem in how the Windows installer build process got done.

I'll note that you can also get this message even if Zope ships with build 204 of pywin32, and properly packaged: if you have an older installation of pywin32 of your own (for example, you have your own Python installation and installed an older pywin32 for that), Zope may pick that one up first. In that case, you'll need to (as the messages you saw said):

"""
Please install (or upgrade) your pywin32 installation (https://sf.net/projects/pywin32)
"""

Mark Hammond checked in a patch today, on the Zope 2.7 branch, that should at least repair the problem with PySECURITY_ATTRIBUTES.

It's possible you can work around the problem by uninstalling other installations of pywin32, or maybe just by removing pywintypes23.dll from your system32 directory.

I also needed to remove pywintypes23.dll from the Zope\bin directory (where an earlier installation put it). Now it seems to work fine.

> Now it seems to work fine.
Using 2.7.7 I mean.

Status: Pending => Resolved

I'm closing this now, since the problems appear to have been fixed in 2.7.7. If someone still has a problem, better to open a new report anyway, since several relevant things that were done wrongly before 2.7.7 did get fixed.
