  The expected behaviour is this:
  - Upon installing Zope2 in a virtualenv a default instance should work with 
no issues.

  What happens instead:
  - The freshly installed Zope instance causes Python to SegFault after only a 
few requests.

  But Python should never SegFault.

2016-06-09 Thread Ján Jockusch 
Confirm that the problem is fixed in yakkety.


I just repeated the test by doing the following on a Ubuntu16.04 installation:

# dpkg -i python2.7-minimal_2.7.11-11_amd64.deb 
libpython2.7-minimal_2.7.11-11_amd64.deb
Preparing to unpack python2.7-minimal_2.7.11-11_amd64.deb ...
Unpacking python2.7-minimal (2.7.11-11) over (2.7.11-11) ...
Preparing to unpack libpython2.7-minimal_2.7.11-11_amd64.deb ...
Unpacking libpython2.7-minimal:amd64 (2.7.11-11) over (2.7.11-7ubuntu1) ...
Setting up libpython2.7-minimal:amd64 (2.7.11-11) ...
Setting up python2.7-minimal (2.7.11-11) ...

After raising the version of the python2.7 executable in this fashion
from 2.7.11-7ubuntu1 to 2.7.11-11 I repeated the testing sequence with
the script I posted earlier, with no problem.


Is there a recommended go-ahead as to which packages I should upgrade?

Will the patch move into 16.04 LTS updates?

Yes, that was exactly the one I wanted to keep out. Sadly, it's not that
simple. Later patches depend on this one. If I also disable those, the
build fails. That's why it's taking so much time...

[Touch-packages] [Bug 1580577] Re: python2.7 crashes with SegFault when running Zope

2016-05-17 Thread Ján Jockusch 
The Debian (testing) version of Python2.7.11 does also exhibit the
problem. I already told the Debian maintainer, Matthias Klose
, via email because I wanted to know exactly where he
prefers to have it posted. He has already contributed here.

@Matthias: The issue remains open. Please advise on how I should proceed
concerning Debian.

In the mean time, I have attempted to narrow the debian/patches/* files
down so I can find which patch produces the problem.

But the patches quite heavily depend on each other, so I have not yet
succeeded in producing a debianized build which does not have the
problem. Still working at that.


The bug can be traced in gdb by executing the testing setup, then saying "gdb 
./zope-virtualenv/bin/python2.7-dbg" and in gdb: "run 
./zope-virtualenv/bin/runzope -C ./zope-virtualenv/instance/etc/zope.conf".

After sending the curl commands to produce the error, gdb exits with the
above mentioned error:

"Fatal Python error: ../Objects/descrobject.c:10 object at 0x1572240 has 
negative ref count -1
Program received signal SIGABRT, Aborted."

Then the stack trace can be inspected. My knowledge of Python's memory
management is not deep enough to really make any sense of what I'm
seeing, other than it looks remotely like a "double free".

I'll try to contribute more. Anyone with better understanding of Python
internals, your help is much appreciated!

2016-05-11 Thread Alexander Loechel 
Hi Patrick,

I think we need to verify that this is in Ubuntu itself, while Ubuntu
just uses the upstream Package from Debian
(https://packages.debian.org/search?keywords=python2.7 /
https://packages.debian.org/stretch/python2.7 or
https://packages.debian.org/sid/python2.7) if they are also affected. If
so, we really need to go upstream for a bug Report on Debian Python 2.7

2016-05-11 Thread Patrick Gerken 
Hi Matthias, I am not sure I understand what you mean by upstream. As you wrote 
this also in the github tracker, I guess you mean to Python directly.
Several Plone developers tested Plone independently with a stock, self compiled 
Python 2.7.11. and confirmed, that their Plone/Zope instance does not segfault. 
So the patches in Ubuntu Python must be the source of the problem.
