We have been working on this as part of a BSP and have some findings.

The problem appears to be when zope2.13, and python-zope.proxy are
installed but NOT python-zope.security. In that situation:

import zope.security
Traceback (most recent call last):
  File "", line 1, in 
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/__init__.py",
 line 19, in

 line 46, in 
from zope.security._proxy import _Proxy as Proxy, getChecker
SystemError: dynamic module not initialized properly

It seems that zope.security gets loaded from the bundled copy, and
zope.proxy from the system. This explodes loudly.

If both or neither external packages are installed, everything is fine.

The reporter got into this situation by installing python-zope.security,
which has a dependency on python-zope.proxy, and then removing
python-zope.security. python-zope.proxy therefore stays around, causing the
SystemError.

Downgrading since it all works fine if both extensions are bundled or both
extensions are external, and 'apt install python-zope.security' does the
right thing.

I notice that the external packages are not the same versions as their
bundled counterparts, so perhaps an interface changed at some point or a
rebuild is needed or something.

After reinstalling zope.security (= reinstalling zope2.13 because that
mega-package contains all the dependencies) and finding nothing changed,
I think I've found the cause - the bug relates to other python-zope.*
packages being installed or not:

If there is no python-zope.* packages installed we have:

$ /usr/lib/zope2.13/bin/python 
>>> import zope.security._proxy
>>> # imported ok

But if we install python-zope.proxy (or thus any package which depends
on it, e.g. python-zodb) we'll have:

$ sudo aptitude install -y python-zope.proxy
$ /usr/lib/zope2.13/bin/python
Traceback (most recent call last):
  File "", line 1, in 
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/__init__.py",
 line 19, in 
from zope.security.management import checkPermission
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/management.py",
 line 23, in 
from zope.security.checker import CheckerPublic
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/checker.py",
 line 46, in 
from zope.security._proxy import _Proxy as Proxy, getChecker
SystemError: dynamic module not initialized properly

and to me this is reproducible 100% - I've tried to remove/install
python-zope.proxy several times and each time the import outcome was
consistent - ok, if no python-zope.proxy installed, SystemError if
installed.

So it looks like the bug relates to zope2.13 being packaged not the
Debian-way - e.g. it have all the dependencies inside it (zope.proxy,
zodb, etc...) instead of using system packages and that shipped
libraries somehow are not 100% isolated from the usual environment.

Thanks,
Kirill

I've tried both recipes on two different sid machines and I am unable to
reproduce the problem.  Importing zope.security._proxy succeeds for me, as
does the dzhandle [...] start command.

Perhaps it's a local problem?  Try re-installing zope.security?

Bug#774213: zope2.13: import zope.security._proxy -> SystemError: dynamic module not initialized properly

2014-12-30 Thread Kirill Smelkov 
Package: zope2.13
Version: 2.13.22-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

With zope2.13 I've tried to create a (user) instance and start it, but a
`SystemError: dynamic module not initialized properly` is raised while
zopectl tries to import zope.security._proxy .

The bug could be demonstrated in essence this way:

$ /usr/lib/zope2.13/bin/python 

>>> import zope.security._proxy
Traceback (most recent call last):
  File "", line 1, in 
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/__init__.py",
 line 19, in 
from zope.security.management import checkPermission
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/management.py",
 line 23, in 
from zope.security.checker import CheckerPublic
  File 
"/usr/lib/zope2.13/lib/python/zope.security-3.7.4.egg/zope/security/checker.py",
 line 46, in 
from zope.security._proxy import _Proxy as Proxy, getChecker
SystemError: dynamic module not initialized properly


Full log demonstrating the problem is attached.

Thanks,
Kirill
