Zope (and Python) crashing bug found
by Andy Dustman 06 Sep '01

06 Sep '01

There have been a couple of reports from various people (myself included) about a bug that will cause Zope to mysteriously die and dump core. I myself had the same problem, particularly with MySQLdb on recent versions of Python. I decided I better hunt the bastard down sooner rather than later... Symptoms: Mysterious core dumps fairly early on after starting up MySQLdb, isolated to the first query. After some investigation, I determined that this did not occur with Python 1.5.2 or 2.0, but does occur with 2.0.1, 2.1, and 2.1.1. Now, when calling _mysql.connect(), one of the items that you MySQLdb will pass in is a type conversion dictionary as a keyword argument, i.e. apply(connect, args, kwargs). After injecting some print statements here and there, and some getrefcount(), I found that the refcount on the converter dictionary was going to zero, i.e. getrefcount() returns 1. However, this only happened with Python > 2.0. So I got out diff and found the critical difference between 2.0 (MySQLdb not broken) and 2.0.1 (MySQLdb broken): diff -u -r Python-2.0/Python/getargs.c Python-2.0.1/Python/getargs.c --- Python-2.0/Python/getargs.c Mon Oct 16 17:49:29 2000 +++ Python-2.0.1/Python/getargs.c Sat Mar 31 08:18:35 2001 @@ -1124,6 +1124,7 @@ return 0; } converted++; + Py_DECREF(item); } else { PyErr_Clear(); The general upshot of this is: In versions of Python (numerically) prior to 2.0.1, if you use the O format with PyArgs_ParseTupleAndKeywords() (and possibly also PyArgs_ParseTuple()) to return a PyObject *, you get a new reference. In 2.0.1 and later, you get a borrowed reference and must Py_INCREF() if you want to keep it. In Python 1.5.2, however, doing this causes a memory leak! Since I want to keep compatibility with Python 1.5.2 for now, my solution is this: if (!conv) conv = PyDict_New(); #if PY_VERSION_HEX > 0x02000100 else Py_INCREF(conv); #endif In this example, conv is initialized to NULL, and PyArgs_ParseTupleAndKeywords() may or may not set it to some object pointer if it was passed in. Since Zope is only going to be supporting 2.1 and newer releases, this is not necessary. However, it may be worth auditing the code to see if the O format is being used, and if so, do Py_INCREF()s need to be added. I suspect some might, since with Python 1.5.2, having them there is a memory leak.

Where is has() defined?
by Kyler B. Laird 05 Sep '01

05 Sep '01

I'm trying to read python/Products/PageTemplates/Expressions.py and python/OFS/Traversable.py but I am at a loss for the definition of has(). I've been grep-ping all over the place trying to find it, with no luck. Is it a Python 2.1 thing? I've tried it in a test script, but I did not succeed. I need a whack with the clue stick. Thank you. --kyler

declarePublic and users
by Richard Jones 04 Sep '01

04 Sep '01

We've just noticed that in zope 2.3.3, using declarePublic has the side-effect of making a request anonymous. That is, a logged-in manager, viewing a declarePublic()'ed page will appear to be anonymous. This isn't mentioned in the manual, and probably should be, assuming it's the desired behaviour. Richard

delObject errors and aq_base
by John Ziniti 04 Sep '01

04 Sep '01

I received an error message when attempting to delete an object: Error Value: examples does not exist 'examples' is a folder from the Zope tutorial. In my messing around, I have found that this occurs because OFS/ObjectManager, in method _getObj, calls (more or less): hasattr(aq_base(self), id) This returns 0 unless I change it to: hasattr(self, id) Further checking shows that self is of type Acquisiton.ImplicitAcquirerWrapper but that aq_base(self) is of type OFS.Folder.Folder. Is this a bug? Is my ZODB hosed (I do a lot of weird stuff)? Any workaround besides changing the code, deleting the objects and changing the code back? Any side-effects to that approach? What did I do to get it like this? -- John Ziniti Channing Laboratory Brigham and Women's Hospital 181 Longwood Avenue Brookline, MA 02115 john.ziniti(a)channing.harvard.edu
