ANN: ConfigObj 4.0.0 Final and Pythonutils 0.2.3
ConfigObj 4.0.0 final and Pythonutils 0.2.3 have just hit the streets. http://www.voidspace.org.uk/python/configobj.html http://www.voidspace.org.uk/python/pythonutils.html They are both pure Python modules - the source distributions include full documentation, which is also online. What's New ? ConfigObj 4.0.0 final has two bugfixes. Using ``setdefault`` to create a new section would return a reference to the dictionary you passed in - not the new section. Also fixed a trivial bug in ``write`` (wouldn't have affected anyone). Pythonutils 0.2.3 is updated to include the ConfigObj 4.0.0 final and cgiutils 0.3.3 ConfigObj is now marked stable. (But caveat emptor :-) What is ConfigObj ? === ConfigObj is a simple but powerful config file reader and writer: an *ini file round tripper*. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though : * Nested sections (subsections), to any level * List values * Multiple line values * String interpolation (substitution) * Integrated with a powerful validation system - including automatic type checking/conversion - repeated sections - and allowing default values * All comments in the file are preserved * The order of keys/sections is preserved * No external dependencies What is Pythonutils ? = The Voidspace Pythonutils package is a simple way of installing the Voidspace collection of modules. Several of the Voidspace Projects depend on these modules. They are also useful in their own right of course. They are primarily general utility modules that simplify common programming tasks in Python. These are currently : * ConfigObj - simple config file handling * validate - validation and type conversion system * listquote - string to list conversion * StandOut - simple logging and output control object * pathutils - for working with paths and files * cgiutils - cgi helpers (and functions for sending emails etc) * urlpath - functions for handling URLs * odict - Ordered Dictionary Class All the best, Fuzzyman http://www.voidspace.org.uk/python -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html

make: circular dependency for Modules/signalmodule.o
Hi group, I'm preparing Python 2.4.2 for the upcoming Minix 3.x release, and I have problems with make. configure runs fine and creates the makefile, but right at the end ends with an error about a circular dependency in Modules/signalmodule.o. I'm new to makefiles and makefile rules, so I can understand what this means, but I don't know how I can fix this problem. Looks like I'll need to rewrite one or more makefile rules and during Minix builds add some code to patch it up for those rules (as opposed to perhaps porting a more capable `make` like gmake right now).

Thanks a lot. Actually you are right I would be trying same thing now. Writing my own custom serializable for the object. But everyone else who face the same problem would come up with their own Serializable code. Can't we plug something into cpickle So that it discards some variable from being serializable.

Iyer, Prasad C wrote: How do I serialize the object color without serializing the x and somechar variables? Is there any modifier which prevents the variable from being serialized. See the pickle documentation. The example given in the documentation pickles a class while excluding one of its attributes. http://www.python.org/doc/2.4.2/lib/pickle-example.html Another question: Is there a concept of private variables? 'private variables' can mean either of two things: hiding the variables to prevent accidental naming conflicts in subclasses, or security to prevent malicious manipulation of a class's internal state. Python provides the former (to a certain extent) when you give an attribute a name prefixed with a double underscore, but makes no attempt to provide the latter. Some other languages (such as C++) make no attempt to provide the former and a completely inadequate attempt at the latter. In other words: Python has a concept of private variables, but it is different than in some other languages, and if you google past threads you can find endless discussions on the pro's and con's of the Python approach. -- http://mail.python.org/mailman/listinfo/python-list

I see it's clear how to modify the behaviour of the descriptor instance, but is he saying I need to mess with the descriptor magic methods so they know what applies to each instance? ## my silly example class ObserverProperty(property): def __init__(self,name,observers=None,validator=None): self._name = name self._observers = observers or [] self._validator = validator or (lambda x: x) self._pName = '_' + name property.__init__(self, fset=lambda inst, value: self.__notify_fset(inst,value), ) def __notify_fset(self,inst,value): value = self._validator(value) for obs in self._observers: obs(inst,self._pName,value) inst.__dict__[self._pName] = value def add(self,obs): self._observers.append(obs) def obs0(inst,pName,value): print 'obs0', inst, pName, value def obs1(inst,pName,value): print 'obs1', inst, pName, value class A(object): x = ObserverProperty('x') a=A() A.x.add(obs0) a.x = 3 b = A() b.x = 4 #I wish I could get b to use obs1 instead of obs0 #without doing the following class B(A): x = ObserverProperty('x',observers=[obs1]) b.__class__ = B b.x = 7 -- Robin Becker -- http://mail.python.org/mailman/listinfo/python-list

ANN: ConfigObj 4.0.0 Final and Pythonutils 0.2.3
ConfigObj 4.0.0 final and Pythonutils 0.2.3 have just hit the streets. http://www.voidspace.org.uk/python/configobj.html http://www.voidspace.org.uk/python/pythonutils.html They are both pure Python modules - the source distributions include full documentation, which is also online. What's New ? ConfigObj 4.0.0 final has two bugfixes. Using ``setdefault`` to create a new section would return a reference to the dictionary you passed in - not the new section. Also fixed a trivial bug in ``write`` (wouldn't have affected anyone). Pythonutils 0.2.3 is updated to include the ConfigObj 4.0.0 final and cgiutils 0.3.3 ConfigObj is now marked stable. (But caveat emptor :-) What is ConfigObj ? === ConfigObj is a simple but powerful config file reader and writer: an *ini file round tripper*. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though : * Nested sections (subsections), to any level * List values * Multiple line values * String interpolation (substitution) * Integrated with a powerful validation system - including automatic type checking/conversion - repeated sections - and allowing default values * All comments in the file are preserved * The order of keys/sections is preserved * No external dependencies What is Pythonutils ? = The Voidspace Pythonutils package is a simple way of installing the Voidspace collection of modules. Several of the Voidspace Projects depend on these modules. They are also useful in their own right of course. They are primarily general utility modules that simplify common programming tasks in Python. These are currently : * ConfigObj - simple config file handling * validate - validation and type conversion system * listquote - string to list conversion * StandOut - simple logging and output control object * pathutils - for working with paths and files * cgiutils - cgi helpers (and functions for sending emails etc) * urlpath - functions for handling URLs * odict - Ordered Dictionary Class All the best, Fuzzyman http://www.voidspace.org.uk/python -- http://mail.python.org/mailman/listinfo/python-list

I don't understand that, because a lot of people seem to use IDEs, and a lot of people seem to use VI/Vim or Emacs.

Re: How to get a raised exception from other thread
Before, after, or during the .start() call, or somewhere else? I'd like to catch *just after* the .start() call. I'm quite sure the problem you are trying to solve can be solved, but you are still describing part of the solution you believe you need, rather than explaining why you want to do this (which may let us show you other, simpler or cleaner ways to accomplish your goals). The thing is that I have in ProgramB a class derived from threading.Thread, that runs a TCPServer, listening to a port on local ip address. As you surely know, you have to specify certain parameters when instantiating the tcpserver: SocketServer.TCPServer(server_address, RequestHandlerClass) where server_address is a tuple (ip,port) ip has to be one of three modes of values (If I remember well): 1. A null string '' Listens on all IP local address 2. A string containing the local IP address where you want it to listen Listens only in the specified local IP address 3. A string containing localhost. Listens only for connections from localhost. Here comes the problem: When you specify the case number 2, the IP must be valid for the computer where the program runs, otherwise, it raises an exception saying that Can't assign requested address. The TCPServer class, defined in a module, is ran (instantiatedly) from the main program through a started thread. The thread also is in the same module as TCPServer class. It looks like (it's much more code than this. If you want the whole code, tell me): MainProgram.py ... SrvrTCP = module.ThreadedTCPServer(ip,port) SrvrTCP.start() #Here, I want to know if the TCPServer started well. ... module.py ... class ThreadedTCPServer(threading.Thread): def __init__(self, ip,port): threading.Thread.__init__(self) self.ip= ip self.port= port def run(self): TCPServer((self.ip,self.port)) #Here, if the self.ip is invalid, it raises an exception. ... -- http://mail.python.org/mailman/listinfo/python-list

Re: PEP: Adding decorators for everything
@GuardedClass class Foo: The functionality can be done using a meta-class, in a similarily declarative way. @Transient a = 'a transient field, ignored when serializing' @Const PI = 22.0 / 7 @TypeSafe(int) count = 10 These are tricky, as the implicitly change the nature of the values - they become properties. And the decorator protocol has to change, as the passed value is obviously not a callable, but a random value. So in the end, you could simply do something like this: @Const(3.24) def PI(self): pass with Const basically ignoring its callable-argument and simply returning a get-only-property. I have to admit that I was tempted to use such a thingy just the other day. But it is not exactly nice, and using PI = Const(3.14) as you suggested is even more pleasing. Additionally, the first @Transient-decorator can't be done that way, as the decorator protocol doesn't know about the _name_ a thing is bound to later. And you'd need that to actually set up e.g. __getstate__ operate properly. And it doesn't mkae much sense anyway, as a is a class variable, not a instance variable.

In the above example, you'd process the nodes in the anchors list to get the desired results. Paul [1] http://www.python.org/pypi/libxml2dom -- http://mail.python.org/mailman/listinfo/python-list
