Property inheritance in Python
by Torsten Landschoff 25 Apr '10

25 Apr '10

Hi Python experts. [It should be obvious, but you can run the code in this message via python -m doctest body.txt if you saved it as body.txt] In an application I develop on I want to use properties instead of the getter/setter paradigm. I ran into a problem overriding a property in a subclass. While I know how to do it with current Python, I propose changing the behaviour to be more consistent. For presentation, here is a stupid example using getters and setters: >>> class BaseGetterSetter(object): ... def get_p(self): ... return self._p ... def set_p(self, value): ... self._p = value >>> class DerivedGetterSetter(BaseGetterSetter): ... def get_p(self): ... return super(DerivedGetterSetter, self).get_p() * 2 ... def set_p(self, value): ... super(DerivedGetterSetter, self).set_p(value / 2) >>> d = DerivedGetterSetter() >>> d.set_p(42) >>> d._p 21 >>> d.get_p() 42 When translating this to use properties, I would come up with something like this: >>> class BaseProp(object): ... @property ... def p(self): ... return self._p ... @p.setter ... def p(self, value): ... self._p = value >>> class DerivedProp(BaseProp): ... @property ... def p(self): ... return super(DerivedProp, self).p * 2 ... @p.setter ... def p(self, value): ... super(DerivedProp, self).p = value / 2 >>> d = DerivedProp() >>> d._p = 21 >>> d.p 42 >>> d.p = 50 Traceback (most recent call last): ... AttributeError: 'super' object has no attribute 'p' As can be seen, using super like in the getter/setter approach above works for fget but not for fset. Support for using the getter via super() was added for Python 2.3 according to http://mail.python.org/pipermail/python-dev/2003-April/034702.html I think it would be more consistent to be able to access the __set__ call via super() as well. Working around -------------- The problematic code boils down to >>> super(DerivedProp, d).p = 1 Traceback (most recent call last): ... AttributeError: 'super' object has no attribute 'p' which can be worked around like this: >>> BaseProp.p.fset(d, 25) >>> BaseProp.p.__set__(d, 10) I'd rather use the method resolution order computed by Python so that mixin classes can extend the behaviour of properties. For that, one can extend super: >>> class duper(super): ... def __setattr__(self, name, value): ... mro = self.__self_class__.__mro__ ... for pos in xrange(len(mro)): ... if mro[pos] == self.__thisclass__: ... break ... for pos in xrange(pos+1, len(mro)): ... tmp = mro[pos] ... if isinstance(tmp, type) and name in tmp.__dict__: ... desc = tmp.__dict__[name] ... desc.__set__(self.__self__, value) ... return >>> duper(DerivedProp, d).p = 100 >>> d.p 200 Extending super --------------- I wrote a test case for the super() behaviour as I would like it to be and implemented the __setattr__ of duper above into super's C implementation. The code is not of production quality and there are some open questions. But I figured that I'd rather ask for opinions before spending even more time on this. The code is available on launchpad at this URL: https://code.launchpad.net/~torsten/python/descr-set-via-super What do you think, do you agree with my understanding or am I completely wrong? Hoping for some insightful comments, Torsten

Inconsistent nesting of scopes in exec(..., locals())
by Joachim B Haga 24 Apr '10

24 Apr '10

There seem to be an inconsistency in the handling of local scopes in exec. Consider the following code, which raises NameError if the '#' is removed from the second last line. block = """ b = 'ok' def f(): print(b) # raises NameError here f() """ scope = locals()#.copy() exec(block, globals(), scope) The intermediate scope is searched for the variable name if the third argument to exec() is locals(), but not if it is locals().copy(). Testing further, it looks like NameError is raised for any dict which is not identically equal to either globals() or locals(). This behaviour is quite unexpected, and I believe it qualifies as a bug. Tested with python 2.6.5 and 3.1.2. -- Joachim B Haga

Unpickling memory usage problem, and a proposed solution
by Dan Gindikin 23 Apr '10

23 Apr '10

We were having performance problems unpickling a large pickle file, we were getting 170s running time (which was fine), but 1100mb memory usage. Memory usage ought to have been about 300mb, this was happening because of memory fragmentation, due to many unnecessary "puts" in the pickle stream. We made a pickletools.optimize inspired tool that could run directly on a pickle file and used pickletools.genops. This solved the unpickling problem (84s, 382mb). However the tool itself was using too much memory and time (1100s, 470mb), so I recoded it to scan through the pickle stream directly, without going through pickletools.genops, giving (240s, 130mb). Other people that deal with large pickle files are probably having similar problems, and since this comes up when dealing with large data it is precisely in this situation that you probably can't use pickletools.optimize or pickletools.genops. It feels like functionality that ought to be added to pickletools, is there some way I can contribute this?

autoconf update to 2.65 and cleanup
by Matthias Klose 23 Apr '10

23 Apr '10

configure is still generated by 2.61; would it be possible to update to 2.65? The cr_lf issue mentioned in [1] seems to be resolved, ac_cr is now defined as ac_cr=`echo X | tr X '\015'` Proposing to - fix some quoting in help strings and code snippets (#8509) - update to autoconf 2.65 (#8510) - convert obsolete macros (AC_HELP_STRING, AC_TRY_*, AC_AIX, ...) one by one (tracking these in separate reports). Could this be done for both trunk and py3k branch, even if 2.7 already is in beta? Matthias [1] http://mail.python.org/pipermail/python-dev/2008-November/083781.html

One final (optional) question/suggestion... should we change from this (in RECORD files): lib/python2.6/site-packages/docutils/__init__.pyc to this: lib/python2.6/site-packages/docutils/__init__.pyc,, In this way, reader code can be written as: for path, hash, size in csv.reader(...): It's not a high-priority thing, but if anybody is writing code to parse RECORD files outside the provided API implementation (eg. system packaging tool authors), they'll probably appreciate this. ;-)

Doctests REPORT_ONLY_FIRST_FAILURE ignored
by Lennart Regebro 22 Apr '10

22 Apr '10

If you set up any sort of report flag on the unit test itself, the default report flags given to the testrunner are ignored. This goes for all report flags, the REPORT_xDIFF and REPORT_ONLY_FIRST_FAILURE. I'd suggest that we do allow the testrunner to set REPORT_ONLY_FIRST_FAILURE by default even if the testcase has a REPORT_xDIFF flag. Why? Because it makes sense. :) The REPORT_xDFF flags makes sense both as parameters to a testrunner, and as flags on a testcase. You might want to permanently set diff flags on tests that generate output that warrants a diff if they fail. REPORT_ONLY_FIRST_FAILURE you would rarely set on a testcase. You don't want that on the testcase, as buildbots wouldn't see the subsequent fails, and developers might think it was only a minor issue. It is a flag you give to the testrunner to stop having the first failure scroll off screen. So you want it to work *always*. You don't want or expect it to stop working just because one testcase had a DIFF flag set. Right? Or did I miss something? If not, I'll provide a patch and put it in the bugtracker. -- Lennart Regebro: http://regebro.wordpress.com/ Python 3 Porting: http://python-incompatibility.googlecode.com/ +33 661 58 14 64

PEP 376
by Tarek Ziadé 22 Apr '10

22 Apr '10

Hello, I think I went through all the latest feedback regarding PEP 376. There will be still some work of course, on the implementation side (for instance the Zip issues described by PJE). But I would like to go ahead and propose PEP 376 for acceptance. If it's accepted, I will implement it in pkgutil for Python 3.2 and provide a backport in distutils2. (In fact Michael Mulich has started this work in distutils2, so it might be done the other way) The next big piece is the FHS-compatible handling of resource files, which will worth a PEP on its own.
