Objects belong to a canvas, and can be moved around on the canvas. They also belong to at most one ``pile'' of objects, and can be transferred between piles (or removed from their pile).

Subject: tkinter "paint" example From: Dave Mitchell To: python-list@cwi.nl Date: Fri, 23 Jan 1998 12:18:05 -0500 (EST) Not too long ago (last week maybe?) someone posted a request for an example of a paint program using Tkinter.

All this does is put up a canvas and draw a smooth black line whenever you have the mouse button down, but hopefully it will be enough to start with..

Select a demoscript from the example menu. The (syntax colored) source code appears in the left source code window. IT CANNOT BE EDITED, but ONLY VIEWED! - Press START button to start the demo. - Stop execution by pressing the STOP button. - Clear screen by pressing the CLEAR button. - Restart by pressing the START button again. SPECIAL demos are those which run EVENTDRIVEN. (For example clock.py - or oldTurtleDemo.py which in the end expects a mouse click.): Press START button to start the demo. - Until the EVENTLOOP is entered everything works as in an ordinary demo script. - When the EVENTLOOP is entered, you control the application by using the mouse and/or keys (or it's controlled by some timer events) To stop it you can and must press the STOP button. While the EVENTLOOP is running, the examples menu is disabled. - Only after having pressed the STOP button, you may restart it or choose another example script. * * * * * * * * In some rare situations there may occur interferences/conflicts between events concerning the demo script and those concerning the demo-viewer. (They run in the same process.) Strange behaviour may be the consequence and in the worst case you must close and restart the viewer. * * * * * * * * (2) How to add your own demos to the demo repository IMPORTANT! When imported, the demo should not modify the system by calling functions in other modules, such as sys, tkinter, or turtle. Global variables should be initialized in main(). - The script name must begin with tdemo_ , so it must have the form tdemo_.py - The code must contain a main() function which will be executed by the viewer (see provided example scripts). It may return a string which will be displayed in the Label below the source code window (when execution has finished.) - In order to run mydemo.py by itself, such as during development, add the following at the end of the file: if __name__ == '__main__': main() mainloop() # keep window python -m turtledemo.mydemo # will then run it - If the demo is EVENT DRIVEN, main must return the string "EVENTLOOP". This informs the demo viewer that the script is still running and must be stopped by the user! If an "EVENTLOOP" demo runs by itself, as with clock, which uses ontimer, or minimal_hanoi, which loops by recursion, then the code should catch the turtle.Terminator exception that will be raised when the user presses the STOP button. (Paint is not such a demo; it only acts in response to mouse clicks and movements.)

It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966. Imagine a robotic turtle starting at (0, 0) in the x-y plane. After an ``import turtle``, give it the command turtle.forward(15), and it moves (on-screen!) 15 pixels in the direction it is facing, drawing a line as it moves. Give it the command turtle.right(25), and it rotates in-place 25 degrees clockwise. By combining together these and similar commands, intricate shapes and pictures can easily be drawn. ----- turtle.py This module is an extended reimplementation of turtle.py from the Python standard distribution up to Python 2.5. (See: http:\\www.python.org) It tries to keep the merits of turtle.py and to be (nearly) 100% compatible with it. This means in the first place to enable the learning programmer to use all the commands, classes and methods interactively when using the module from within IDLE run with the -n switch. Roughly it has the following features added: - Better animation of the turtle movements, especially of turning the turtle. So the turtles can more easily be used as a visual feedback instrument by the (beginning) programmer. - Different turtle shapes, gif-images as turtle shapes, user defined and user controllable turtle shapes, among them compound (multicolored) shapes. Turtle shapes can be stgretched and tilted, which makes turtles zu very versatile geometrical objects. - Fine control over turtle movement and screen updates via delay(), and enhanced tracer() and speed() methods. - Aliases for the most commonly used commands, like fd for forward etc., following the early Logo traditions. This reduces the boring work of typing long sequences of commands, which often occur in a natural way when kids try to program fancy pictures on their first encounter with turtle graphcis. - Turtles now have an undo()-method with configurable undo-buffer. - Some simple commands/methods for creating event driven programs (mouse-, key-, timer-events). Especially useful for programming games. - A scrollable Canvas class. The default scrollable Canvas can be extended interactively as needed while playing around with the turtle(s). - A TurtleScreen class with methods controlling background color or background image, window and canvas size and other properties of the TurtleScreen. - There is a method, setworldcoordinates(), to install a user defined coordinate-system for the TurtleScreen. - The implementation uses a 2-vector class named Vec2D, derived from tuple. This class is public, so it can be imported by the application programmer, which makes certain types of computations very natural and compact. - Appearance of the TurtleScreen and the Turtles at startup/import can be configured by means of a turtle.cfg configuration file. The default configuration mimics the appearance of the old turtle module. - If configured appropriately the module reads in docstrings from a docstring dictionary in some different language, supplied separately and replaces the english ones by those read in. There is a utility function write_docstringdict() to write a dictionary with the original (english) docstrings to disc, so it can serve as a template for translations.

xdrlib.py *** There are two library modules, xdr.py and rpc.py, and several example clients: mountclient.py, nfsclient.py, and rnusersclient.py, implementing the NFS Mount protocol, (part of) the NFS protocol, and the "rnusers" protocol (used by rusers(1)), respectively. The latter demonstrates the use of broadcast via the Port mapper's CALLIT procedure. There is also a way to create servers in Python. To test the nfs client, run it from the shell with something like this: python -c 'import nfsclient; nfsclient.test()' [hostname [filesystemname]] When called without a filesystemname, it lists the filesystems at the host; default host is the local machine. Other clients are tested similarly. For hostname, use e.g. wuarchive.wustl.edu or gatekeeper.dec.com (two hosts that are known to export NFS filesystems with little restrictions). There are now two different RPC compilers: 1) Wim Lewis rpcgen.py found on http://www.omnigroup.com/~wiml/soft/stale-index.html#python. 2) Peter strands rpcgen.py, which is part of "pynfs" (http://www.cendio.se/~peter/pynfs/).

For example, class C: def m1(self, arg): require arg > 0 return whatever ensure Result > arg can be written (clumsily, I agree) as: class C(Eiffel): def m1(self, arg): return whatever def m1_pre(self, arg): assert arg > 0 def m1_post(self, Result, arg): assert Result > arg Pre- and post-conditions for a method, being implemented as methods themselves, are inherited independently from the method. This gives much of the same effect of Eiffel, where pre- and post-conditions are inherited when a method is overridden by a derived class. However, when a derived class in Python needs to extend a pre- or post-condition, it must manually merge the base class' pre- or post-condition with that defined in the derived class', for example: class D(C): def m1(self, arg): return arg**2 def m1_post(self, Result, arg): C.m1_post(self, Result, arg) assert Result < 100 This gives derived classes more freedom but also more responsibility than in Eiffel, where the compiler automatically takes care of this. In Eiffel, pre-conditions combine using contravariance, meaning a derived class can only make a pre-condition weaker; in Python, this is up to the derived class. For example, a derived class that takes away the requirement that arg > 0 could write: def m1_pre(self, arg): pass but one could equally write a derived class that makes a stronger requirement: def m1_pre(self, arg): require arg > 50 It would be easy to modify the classes shown here so that pre- and post-conditions can be disabled (separately, on a per-class basis). A different design would have the pre- or post-condition testing functions return true for success and false for failure. This would make it possible to implement automatic combination of inherited and new pre-/post-conditions.

Metaclasses in Python 1.5

(A.k.a. The Killer Joke :-)

(Postscript: reading this essay is probably not the best way to understand the metaclass hook described here. See a message posted by Vladimir Marangozov which may give a gentler introduction to the matter. You may also want to search Deja News for messages with "metaclass" in the subject posted to comp.lang.python in July and August 1998.)

In previous Python releases (and still in 1.5), there is something called the ``Don Beaudry hook'', after its inventor and champion. This allows C extensions to provide alternate class behavior, thereby allowing the Python class syntax to be used to define other class-like entities. Don Beaudry has used this in his infamous MESS package; Jim Fulton has used it in his Extension Classes package. (It has also been referred to as the ``Don Beaudry hack,'' but that's a misnomer. There's nothing hackish about it -- in fact, it is rather elegant and deep, even though there's something dark to it.)

(On first reading, you may want to skip directly to the examples in the section "Writing Metaclasses in Python" below, unless you want your head to explode.)

Documentation of the Don Beaudry hook has purposefully been kept minimal, since it is a feature of incredible power, and is easily abused. Basically, it checks whether the type of the base class is callable, and if so, it is called to create the new class.

Note the two indirection levels. Take a simple example: 

class B:
    pass

class C(B):
    pass
Take a look at the second class definition, and try to fathom ``the type of the base class is callable.''

(Types are not classes, by the way. See questions 4.2, 4.19 and in particular 6.22 in the Python FAQ for more on this topic.)

  • The base class is B; this one's easy.

  • Since B is a class, its type is ``class''; so the type of the base class is the type ``class''. This is also known as types.ClassType, assuming the standard module types has been imported.

  • Now is the type ``class'' callable? No, because types (in core Python) are never callable. Classes are callable (calling a class creates a new instance) but types aren't.

So our conclusion is that in our example, the type of the base class (of C) is not callable. So the Don Beaudry hook does not apply, and the default class creation mechanism is used (which is also used when there is no base class). In fact, the Don Beaudry hook never applies when using only core Python, since the type of a core object is never callable.

So what do Don and Jim do in order to use Don's hook? Write an extension that defines at least two new Python object types. The first would be the type for ``class-like'' objects usable as a base class, to trigger Don's hook. This type must be made callable. That's why we need a second type. Whether an object is callable depends on its type. So whether a type object is callable depends on its type, which is a meta-type. (In core Python there is only one meta-type, the type ``type'' (types.TypeType), which is the type of all type objects, even itself.) A new meta-type must be defined that makes the type of the class-like objects callable. (Normally, a third type would also be needed, the new ``instance'' type, but this is not an absolute requirement -- the new class type could return an object of some existing type when invoked to create an instance.)

Still confused? Here's a simple device due to Don himself to explain metaclasses. Take a simple class definition; assume B is a special class that triggers Don's hook: 

class C(B):
    a = 1
    b = 2
This can be though of as equivalent to: 
C = type(B)('C', (B,), {'a': 1, 'b': 2})
If that's too dense for you, here's the same thing written out using temporary variables: 
creator = type(B)               # The type of the base class
name = 'C'                      # The name of the new class
bases = (B,)                    # A tuple containing the base class(es)
namespace = {'a': 1, 'b': 2}    # The namespace of the class statement
C = creator(name, bases, namespace)
This is analogous to what happens without the Don Beaudry hook, except that in that case the creator function is set to the default class creator.

In either case, the creator is called with three arguments. The first one, name, is the name of the new class (as given at the top of the class statement). The bases argument is a tuple of base classes (a singleton tuple if there's only one base class, like the example). Finally, namespace is a dictionary containing the local variables collected during execution of the class statement.

Note that the contents of the namespace dictionary is simply whatever names were defined in the class statement. A little-known fact is that when Python executes a class statement, it enters a new local namespace, and all assignments and function definitions take place in this namespace. Thus, after executing the following class statement: 

class C:
    a = 1
    def f(s): pass
the class namespace's contents would be {'a': 1, 'f': <function f ...>}.

But enough already about writing Python metaclasses in C; read the documentation of MESS or Extension Classes for more information.

Writing Metaclasses in Python

In Python 1.5, the requirement to write a C extension in order to write metaclasses has been dropped (though you can still do it, of course). In addition to the check ``is the type of the base class callable,'' there's a check ``does the base class have a __class__ attribute.'' If so, it is assumed that the __class__ attribute refers to a class.

Let's repeat our simple example from above: 

class C(B):
    a = 1
    b = 2
Assuming B has a __class__ attribute, this translates into: 
C = B.__class__('C', (B,), {'a': 1, 'b': 2})
This is exactly the same as before except that instead of type(B), B.__class__ is invoked. If you have read FAQ question 6.22 you will understand that while there is a big technical difference between type(B) and B.__class__, they play the same role at different abstraction levels. And perhaps at some point in the future they will really be the same thing (at which point you would be able to derive subclasses from built-in types).

At this point it may be worth mentioning that C.__class__ is the same object as B.__class__, i.e., C's metaclass is the same as B's metaclass. In other words, subclassing an existing class creates a new (meta)inststance of the base class's metaclass.

Going back to the example, the class B.__class__ is instantiated, passing its constructor the same three arguments that are passed to the default class constructor or to an extension's metaclass: name, bases, and namespace.

It is easy to be confused by what exactly happens when using a metaclass, because we lose the absolute distinction between classes and instances: a class is an instance of a metaclass (a ``metainstance''), but technically (i.e. in the eyes of the python runtime system), the metaclass is just a class, and the metainstance is just an instance. At the end of the class statement, the metaclass whose metainstance is used as a base class is instantiated, yielding a second metainstance (of the same metaclass). This metainstance is then used as a (normal, non-meta) class; instantiation of the class means calling the metainstance, and this will return a real instance. And what class is that an instance of? Conceptually, it is of course an instance of our metainstance; but in most cases the Python runtime system will see it as an instance of a helper class used by the metaclass to implement its (non-meta) instances...

Hopefully an example will make things clearer. Let's presume we have a metaclass MetaClass1. It's helper class (for non-meta instances) is callled HelperClass1. We now (manually) instantiate MetaClass1 once to get an empty special base class: 

BaseClass1 = MetaClass1("BaseClass1", (), {})
We can now use BaseClass1 as a base class in a class statement: 
class MySpecialClass(BaseClass1):
    i = 1
    def f(s): pass
At this point, MySpecialClass is defined; it is a metainstance of MetaClass1 just like BaseClass1, and in fact the expression ``BaseClass1.__class__ == MySpecialClass.__class__ == MetaClass1'' yields true.

We are now ready to create instances of MySpecialClass. Let's assume that no constructor arguments are required: 

x = MySpecialClass()
y = MySpecialClass()
print x.__class__, y.__class__
The print statement shows that x and y are instances of HelperClass1. How did this happen? MySpecialClass is an instance of MetaClass1 (``meta'' is irrelevant here); when an instance is called, its __call__ method is invoked, and presumably the __call__ method defined by MetaClass1 returns an instance of HelperClass1.

Now let's see how we could use metaclasses -- what can we do with metaclasses that we can't easily do without them? Here's one idea: a metaclass could automatically insert trace calls for all method calls. Let's first develop a simplified example, without support for inheritance or other ``advanced'' Python features (we'll add those later). 

import types

class Tracing:
    def __init__(self, name, bases, namespace):
        """Create a new class."""
        self.__name__ = name
        self.__bases__ = bases
        self.__namespace__ = namespace
    def __call__(self):
        """Create a new instance."""
        return Instance(self)

class Instance:
    def __init__(self, klass):
        self.__klass__ = klass
    def __getattr__(self, name):
        try:
            value = self.__klass__.__namespace__[name]
        except KeyError:
            raise AttributeError, name
        if type(value) is not types.FunctionType:
            return value
        return BoundMethod(value, self)

class BoundMethod:
    def __init__(self, function, instance):
        self.function = function
        self.instance = instance
    def __call__(self, *args):
        print "calling", self.function, "for", self.instance, "with", args
        return apply(self.function, (self.instance,) + args)

Trace = Tracing('Trace', (), {})

class MyTracedClass(Trace):
    def method1(self, a):
        self.a = a
    def method2(self):
        return self.a

aninstance = MyTracedClass()

aninstance.method1(10)

print "the answer is %d" % aninstance.method2()
Confused already? The intention is to read this from top down. The Tracing class is the metaclass we're defining. Its structure is really simple.

  • The __init__ method is invoked when a new Tracing instance is created, e.g. the definition of class MyTracedClass later in the example. It simply saves the class name, base classes and namespace as instance variables.

  • The __call__ method is invoked when a Tracing instance is called, e.g. the creation of aninstance later in the example. It returns an instance of the class Instance, which is defined next.

The class Instance is the class used for all instances of classes built using the Tracing metaclass, e.g. aninstance. It has two methods:

  • The __init__ method is invoked from the Tracing.__call__ method above to initialize a new instance. It saves the class reference as an instance variable. It uses a funny name because the user's instance variables (e.g. self.a later in the example) live in the same namespace.

  • The __getattr__ method is invoked whenever the user code references an attribute of the instance that is not an instance variable (nor a class variable; but except for __init__ and __getattr__ there are no class variables). It will be called, for example, when aninstance.method1 is referenced in the example, with self set to aninstance and name set to the string "method1".

The __getattr__ method looks the name up in the __namespace__ dictionary. If it isn't found, it raises an AttributeError exception. (In a more realistic example, it would first have to look through the base classes as well.) If it is found, there are two possibilities: it's either a function or it isn't. If it's not a function, it is assumed to be a class variable, and its value is returned. If it's a function, we have to ``wrap'' it in instance of yet another helper class, BoundMethod.

The BoundMethod class is needed to implement a familiar feature: when a method is defined, it has an initial argument, self, which is automatically bound to the relevant instance when it is called. For example, aninstance.method1(10) is equivalent to method1(aninstance, 10). In the example if this call, first a temporary BoundMethod instance is created with the following constructor call: temp = BoundMethod(method1, aninstance); then this instance is called as temp(10). After the call, the temporary instance is discarded.

  • The __init__ method is invoked for the constructor call BoundMethod(method1, aninstance). It simply saves away its arguments.

  • The __call__ method is invoked when the bound method instance is called, as in temp(10). It needs to call method1(aninstance, 10). However, even though self.function is now method1 and self.instance is aninstance, it can't call self.function(self.instance, args) directly, because it should work regardless of the number of arguments passed. (For simplicity, support for keyword arguments has been omitted.)

In order to be able to support arbitrary argument lists, the __call__ method first constructs a new argument tuple. Conveniently, because of the notation *args in __call__'s own argument list, the arguments to __call__ (except for self) are placed in the tuple args. To construct the desired argument list, we concatenate a singleton tuple containing the instance with the args tuple: (self.instance,) + args. (Note the trailing comma used to construct the singleton tuple.) In our example, the resulting argument tuple is (aninstance, 10).

The intrinsic function apply() takes a function and an argument tuple and calls the function for it. In our example, we are calling apply(method1, (aninstance, 10)) which is equivalent to calling method(aninstance, 10).

From here on, things should come together quite easily. The output of the example code is something like this: 

calling <function method1 at ae8d8> for <Instance instance at 95ab0> with (10,)
calling <function method2 at ae900> for <Instance instance at 95ab0> with ()
the answer is 10

That was about the shortest meaningful example that I could come up with. A real tracing metaclass (for example, Trace.py discussed below) needs to be more complicated in two dimensions.

First, it needs to support more advanced Python features such as class variables, inheritance, __init__ methods, and keyword arguments.

Second, it needs to provide a more flexible way to handle the actual tracing information; perhaps it should be possible to write your own tracing function that gets called, perhaps it should be possible to enable and disable tracing on a per-class or per-instance basis, and perhaps a filter so that only interesting calls are traced; it should also be able to trace the return value of the call (or the exception it raised if an error occurs). Even the Trace.py example doesn't support all these features yet.

Real-life Examples

Have a look at some very preliminary examples that I coded up to teach myself how to write metaclasses:

Enum.py
This (ab)uses the class syntax as an elegant way to define enumerated types. The resulting classes are never instantiated -- rather, their class attributes are the enumerated values. For example: 
class Color(Enum):
    red = 1
    green = 2
    blue = 3
print Color.red
will print the string ``Color.red'', while ``Color.red==1'' is true, and ``Color.red + 1'' raise a TypeError exception.

Trace.py
The resulting classes work much like standard classes, but by setting a special class or instance attribute __trace_output__ to point to a file, all calls to the class's methods are traced. It was a bit of a struggle to get this right. This should probably redone using the generic metaclass below.

Meta.py
A generic metaclass. This is an attempt at finding out how much standard class behavior can be mimicked by a metaclass. The preliminary answer appears to be that everything's fine as long as the class (or its clients) don't look at the instance's __class__ attribute, nor at the class's __dict__ attribute. The use of __getattr__ internally makes the classic implementation of __getattr__ hooks tough; we provide a similar hook _getattr_ instead. (__setattr__ and __delattr__ are not affected.) (XXX Hm. Could detect presence of __getattr__ and rename it.)

Eiffel.py
Uses the above generic metaclass to implement Eiffel style pre-conditions and post-conditions.

Synch.py
Uses the above generic metaclass to implement synchronized methods.

Simple.py
The example module used above.

A pattern seems to be emerging: almost all these uses of metaclasses (except for Enum, which is probably more cute than useful) mostly work by placing wrappers around method calls. An obvious problem with that is that it's not easy to combine the features of different metaclasses, while this would actually be quite useful: for example, I wouldn't mind getting a trace from the test run of the Synch module, and it would be interesting to add preconditions to it as well. This needs more research. Perhaps a metaclass could be provided that allows stackable wrappers...

Things You Could Do With Metaclasses

There are lots of things you could do with metaclasses. Most of these can also be done with creative use of __getattr__, but metaclasses make it easier to modify the attribute lookup behavior of classes. Here's a partial list.

  • Enforce different inheritance semantics, e.g. automatically call base class methods when a derived class overrides

  • Implement class methods (e.g. if the first argument is not named 'self')

  • Implement that each instance is initialized with copies of all class variables

  • Implement a different way to store instance variables (e.g. in a list kept outside the instance but indexed by the instance's id())

  • Automatically wrap or trap all or certain methods
    • for tracing
    • for precondition and postcondition checking
    • for synchronized methods
    • for automatic value caching

  • When an attribute is a parameterless function, call it on reference (to mimic it being an instance variable); same on assignment

  • Instrumentation: see how many times various attributes are used

  • Different semantics for __setattr__ and __getattr__ (e.g. disable them when they are being used recursively)

  • Abuse class syntax for other things

  • Experiment with automatic type checking

  • Delegation (or acquisition)

  • Dynamic inheritance patterns

  • Automatic caching of methods

Many thanks to David Ascher and Donald Beaudry for their comments on earlier draft of this paper. Also thanks to Matt Conway and Tommy Burnette for putting a seed for the idea of metaclasses in my mind, nearly three years ago, even though at the time my response was ``you can do that with __getattr__ hooks...'' :-)

For example, class C: def m1(self, arg): require arg > 0 return whatever ensure Result > arg can be written (clumsily, I agree) as: class C(Eiffel): def m1(self, arg): return whatever def m1_pre(self, arg): assert arg > 0 def m1_post(self, Result, arg): assert Result > arg Pre- and post-conditions for a method, being implemented as methods themselves, are inherited independently from the method. This gives much of the same effect of Eiffel, where pre- and post-conditions are inherited when a method is overridden by a derived class. However, when a derived class in Python needs to extend a pre- or post-condition, it must manually merge the base class' pre- or post-condition with that defined in the derived class', for example: class D(C): def m1(self, arg): return arg**2 def m1_post(self, Result, arg): C.m1_post(self, Result, arg) assert Result < 100 This gives derived classes more freedom but also more responsibility than in Eiffel, where the compiler automatically takes care of this. In Eiffel, pre-conditions combine using contravariance, meaning a derived class can only make a pre-condition weaker; in Python, this is up to the derived class. For example, a derived class that takes away the requirement that arg > 0 could write: def m1_pre(self, arg): pass but one could equally write a derived class that makes a stronger requirement: def m1_pre(self, arg): require arg > 50 It would be easy to modify the classes shown here so that pre- and post-conditions can be disabled (separately, on a per-class basis). A different design would have the pre- or post-condition testing functions return true for success and false for failure. This would make it possible to implement automatic combination of inherited and new pre-/post-conditions. All this is left as an exercise to the reader.

For example, class C: def m1(self, arg): require arg > 0 return whatever ensure Result > arg can be written (clumsily, I agree) as: class C(Eiffel): def m1(self, arg): return whatever def m1_pre(self, arg): assert arg > 0 def m1_post(self, Result, arg): assert Result > arg Pre- and post-conditions for a method, being implemented as methods themselves, are inherited independently from the method. This gives much of the same effect of Eiffel, where pre- and post-conditions are inherited when a method is overridden by a derived class. However, when a derived class in Python needs to extend a pre- or post-condition, it must manually merge the base class' pre- or post-condition with that defined in the derived class', for example: class D(C): def m1(self, arg): return arg**2 def m1_post(self, Result, arg): C.m1_post(self, Result, arg) assert Result < 100 This gives derived classes more freedom but also more responsibility than in Eiffel, where the compiler automatically takes care of this. In Eiffel, pre-conditions combine using contravariance, meaning a derived class can only make a pre-condition weaker; in Python, this is up to the derived class. For example, a derived class that takes away the requirement that arg > 0 could write: def m1_pre(self, arg): pass but one could equally write a derived class that makes a stronger requirement: def m1_pre(self, arg): require arg > 50 It would be easy to modify the classes shown here so that pre- and post-conditions can be disabled (separately, on a per-class basis). A different design would have the pre- or post-condition testing functions return true for success and false for failure. This would make it possible to implement automatic combination of inherited and new pre-/post-conditions. All this is left as an exercise to the reader. i(t MetaClasst MetaHelpertMetaMethodWrappertEiffelMethodWrappercBseZdZdZRS(cCstj|||yt||jd|_Wntk rLd|_nXyt||jd|_Wntk rd|_nXdS(Nt_pret_post(Rt__init__tgetattrt__name__tpretAttributeErrortNonetpost(tselftfunctinst((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyRDs   cOsh|jrt|j||nt|j|jf||}|jrdt|j|f||n|S(N(R tapplyRRR (R targstkwtResult((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyt__call__Ss   (Rt __module__RR(((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyRBs t EiffelHelpercBseZeZRS((RRRt__methodwrapper__(((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyR[stEiffelMetaClasscBseZeZRS((RRRt __helper__(((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyR^stEiffelcCs0dtfdY}|}|jddS(NtCcBs#eZdZdZdZRS(cSs|dS(Ni((R targ((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pytm1fscSs|dkstddS(Nisprecondition for m1 failed(tAssertionError(R R((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pytm1_prehscSs||kstdS(N(R(R RR((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pytm1_postjs(RRRRR (((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyRes  i (RR(Rtx((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyt_testds t__main__N(( t__doc__tMetaRRRRRRRR"R(((s//usr/lib64/python2.7/Demo/metaclasses/Eiffel.pyt>s PK%L]L!!metaclasses/Synch.pycnu[ ^c@sdZddlZdddYZdZddlmZmZmZdefdYZd efd YZ d efd YZ e d diZ dZ e dkree ndS(s`Synchronization metaclass.

I understand that anybody's interpretation of the meta-class concept is likely to be difficult to digest by others. Here's another try, expressing the same thing, but using the Python programming model, examples and, perhaps, more popular terms. 1. Classes. This is pure Python of today. Sorry about the tutorial, but it is meant to illustrate the second part, which is the one we're interested in and which will follow the same development scenario. Besides, newbies are likely to understand that the discussion is affordable even for them :-) a) Class definition A class is meant to define the common properties of a set of objects. A class is a "package" of properties. The assembly of properties in a class package is sometimes called a class structure (which isn't always appropriate). >>> class A: attr1 = "Hello" # an attribute of A def method1(self, *args): pass # method1 of A def method2(self, *args): pass # method2 of A >>> So far, we defined the structure of the class A. The class A is of type . We can check this by asking Python: "what is A?" >>> A # What is A? b) Class instantiation Creating an object with the properties defined in the class A is called instantiation of the class A. After an instantiation of A, we obtain a new object, called an instance, which has the properties packaged in the class A. >>> a = A() # 'a' is the 1st instance of A >>> a # What is 'a'? <__main__.A instance at 2022b9d0> >>> b = A() # 'b' is another instance of A >>> b # What is 'b'? <__main__.A instance at 2022b9c0> The objects, 'a' and 'b', are of type and they both have the same properties. Note, that 'a' and 'b' are different objects. (their adresses differ). This is a bit hard to see, so let's ask Python: >>> a == b # Is 'a' the same object as 'b'? 0 # No. Instance objects have one more special property, indicating the class they are an instance of. This property is named __class__. >>> a.__class__ # What is the class of 'a'? # 'a' is an instance of A >>> b.__class__ # What is the class of 'b'? # 'b' is an instance of A >>> a.__class__ == b.__class__ # Is it really the same class A? 1 # Yes. c) Class inheritance (class composition and specialization) Classes can be defined in terms of other existing classes (and only classes! -- don't bug me on this now). Thus, we can compose property packages and create new ones. We reuse the property set defined in a class by defining a new class, which "inherits" from the former. In other words, a class B which inherits from the class A, inherits the properties defined in A, or, B inherits the structure of A. In the same time, at the definition of the new class B, we can enrich the inherited set of properties by adding new ones and/or modify some of the inherited properties. >>> class B(A): # B inherits A's properties attr2 = "World" # additional attr2 def method2(self, arg1): pass # method2 is redefined def method3(self, *args): pass # additional method3 >>> B # What is B? >>> B == A # Is B the same class as A? 0 # No. Classes define one special property, indicating whether a class inherits the properties of another class. This property is called __bases__ and it contains a list (a tuple) of the classes the new class inherits from. The classes from which a class is inheriting the properties are called superclasses (in Python, we call them also -- base classes). >>> A.__bases__ # Does A have any superclasses? () # No. >>> B.__bases__ # Does B have any superclasses? (,) # Yes. It has one superclass. >>> B.__bases__[0] == A # Is it really the class A? 1 # Yes, it is. -------- Congratulations on getting this far! This was the hard part. Now, let's continue with the easy one. -------- 2. Meta-classes You have to admit, that an anonymous group of Python wizards are not satisfied with the property packaging facilities presented above. They say, that the Real-World bugs them with problems that cannot be modelled successfully with classes. Or, that the way classes are implemented in Python and the way classes and instances behave at runtime isn't always appropriate for reproducing the Real-World's behavior in a way that satisfies them. Hence, what they want is the following: a) leave objects as they are (instances of classes) b) leave classes as they are (property packages and object creators) BUT, at the same time: c) consider classes as being instances of mysterious objects. d) label mysterious objects "meta-classes". Easy, eh? You may ask: "Why on earth do they want to do that?". They answer: "Poor soul... Go and see how cruel the Real-World is!". You - fuzzy: "OK, will do!" And here we go for another round of what I said in section 1 -- Classes. However, be warned! The features we're going to talk about aren't fully implemented yet, because the Real-World don't let wizards to evaluate precisely how cruel it is, so the features are still highly-experimental. a) Meta-class definition A meta-class is meant to define the common properties of a set of classes. A meta-class is a "package" of properties. The assembly of properties in a meta-class package is sometimes called a meta-class structure (which isn't always appropriate). In Python, a meta-class definition would have looked like this: >>> metaclass M: attr1 = "Hello" # an attribute of M def method1(self, *args): pass # method1 of M def method2(self, *args): pass # method2 of M >>> So far, we defined the structure of the meta-class M. The meta-class M is of type . We cannot check this by asking Python, but if we could, it would have answered: >>> M # What is M? b) Meta-class instantiation Creating an object with the properties defined in the meta-class M is called instantiation of the meta-class M. After an instantiation of M, we obtain a new object, called an class, but now it is called also a meta-instance, which has the properties packaged in the meta-class M. In Python, instantiating a meta-class would have looked like this: >>> A = M() # 'A' is the 1st instance of M >>> A # What is 'A'? >>> B = M() # 'B' is another instance of M >>> B # What is 'B'? The metaclass-instances, A and B, are of type and they both have the same properties. Note, that A and B are different objects. (their adresses differ). This is a bit hard to see, but if it was possible to ask Python, it would have answered: >>> A == B # Is A the same class as B? 0 # No. Class objects have one more special property, indicating the meta-class they are an instance of. This property is named __metaclass__. >>> A.__metaclass__ # What is the meta-class of A? # A is an instance of M >>> A.__metaclass__ # What is the meta-class of B? # B is an instance of M >>> A.__metaclass__ == B.__metaclass__ # Is it the same meta-class M? 1 # Yes. c) Meta-class inheritance (meta-class composition and specialization) Meta-classes can be defined in terms of other existing meta-classes (and only meta-classes!). Thus, we can compose property packages and create new ones. We reuse the property set defined in a meta-class by defining a new meta-class, which "inherits" from the former. In other words, a meta-class N which inherits from the meta-class M, inherits the properties defined in M, or, N inherits the structure of M. In the same time, at the definition of the new meta-class N, we can enrich the inherited set of properties by adding new ones and/or modify some of the inherited properties. >>> metaclass N(M): # N inherits M's properties attr2 = "World" # additional attr2 def method2(self, arg1): pass # method2 is redefined def method3(self, *args): pass # additional method3 >>> N # What is N? >>> N == M # Is N the same meta-class as M? 0 # No. Meta-classes define one special property, indicating whether a meta-class inherits the properties of another meta-class. This property is called __metabases__ and it contains a list (a tuple) of the meta-classes the new meta-class inherits from. The meta-classes from which a meta-class is inheriting the properties are called super-meta-classes (in Python, we call them also -- super meta-bases). >>> M.__metabases__ # Does M have any supermetaclasses? () # No. >>> N.__metabases__ # Does N have any supermetaclasses? (,) # Yes. It has a supermetaclass. >>> N.__metabases__[0] == M # Is it really the meta-class M? 1 # Yes, it is. -------- Triple congratulations on getting this far!

The routine that first executes # co.tran is called the "main coroutine". It's special in several # respects: it existed before you created the Coroutine object; if any of # the create'd coroutines exits (does a return, or suffers an unhandled # exception), EarlyExit error is raised in the main coroutine; and the # co.detach() method transfers control directly to the main coroutine # (you can't use co.tran() for this because the main coroutine doesn't # have a name ...). # # Coroutine objects support these methods: # # handle = .create(func [, arg1, arg2, ...]) # Creates a coroutine for an invocation of func(arg1, arg2, ...), # and returns a handle ("name") for the coroutine so created. The # handle can be used as the target in a subsequent .tran(). # # .tran(target, data=None) # Transfer control to the create'd coroutine "target", optionally # passing it an arbitrary piece of data. To the coroutine A that does # the .tran, .tran acts like an ordinary function call: another # coroutine B can .tran back to it later, and if it does A's .tran # returns the 'data' argument passed to B's tran. E.g., # # in coroutine coA in coroutine coC in coroutine coB # x = co.tran(coC) co.tran(coB) co.tran(coA,12) # print x # 12 # # The data-passing feature is taken from Icon, and greatly cuts # the need to use global variables for inter-coroutine communication. # # .back( data=None ) # The same as .tran(invoker, data=None), where 'invoker' is the # coroutine that most recently .tran'ed control to the coroutine # doing the .back. This is akin to Icon's "&source". # # .detach( data=None ) # The same as .tran(main, data=None), where 'main' is the # (unnameable!) coroutine that started it all.

PK%L]eITTthreads/sync.pynu[# Defines classes that provide synchronization objects. Note that use of # this module requires that your Python support threads. # # condition(lock=None) # a POSIX-like condition-variable object # barrier(n) # an n-thread barrier # event() # an event object # semaphore(n=1) # a semaphore object, with initial count n # mrsw() # a multiple-reader single-writer lock # # CONDITIONS # # A condition object is created via # import this_module # your_condition_object = this_module.condition(lock=None) # # As explained below, a condition object has a lock associated with it, # used in the protocol to protect condition data. You can specify a # lock to use in the constructor, else the constructor will allocate # an anonymous lock for you. Specifying a lock explicitly can be useful # when more than one condition keys off the same set of shared data. # # Methods: # .acquire() # acquire the lock associated with the condition # .release() # release the lock associated with the condition # .wait() # block the thread until such time as some other thread does a # .signal or .broadcast on the same condition, and release the # lock associated with the condition. The lock associated with # the condition MUST be in the acquired state at the time # .wait is invoked. # .signal() # wake up exactly one thread (if any) that previously did a .wait # on the condition; that thread will awaken with the lock associated # with the condition in the acquired state. If no threads are # .wait'ing, this is a nop. If more than one thread is .wait'ing on # the condition, any of them may be awakened. # .broadcast() # wake up all threads (if any) that are .wait'ing on the condition; # the threads are woken up serially, each with the lock in the # acquired state, so should .release() as soon as possible. If no # threads are .wait'ing, this is a nop. # # Note that if a thread does a .wait *while* a signal/broadcast is # in progress, it's guaranteeed to block until a subsequent # signal/broadcast. # # Secret feature: `broadcast' actually takes an integer argument, # and will wake up exactly that many waiting threads (or the total # number waiting, if that's less). Use of this is dubious, though, # and probably won't be supported if this form of condition is # reimplemented in C. # # DIFFERENCES FROM POSIX # # + A separate mutex is not needed to guard condition data. Instead, a # condition object can (must) be .acquire'ed and .release'ed directly. # This eliminates a common error in using POSIX conditions. # # + Because of implementation difficulties, a POSIX `signal' wakes up # _at least_ one .wait'ing thread. Race conditions make it difficult # to stop that. This implementation guarantees to wake up only one, # but you probably shouldn't rely on that. # # PROTOCOL # # Condition objects are used to block threads until "some condition" is # true. E.g., a thread may wish to wait until a producer pumps out data # for it to consume, or a server may wish to wait until someone requests # its services, or perhaps a whole bunch of threads want to wait until a # preceding pass over the data is complete. Early models for conditions # relied on some other thread figuring out when a blocked thread's # condition was true, and made the other thread responsible both for # waking up the blocked thread and guaranteeing that it woke up with all # data in a correct state. This proved to be very delicate in practice, # and gave conditions a bad name in some circles. # # The POSIX model addresses these problems by making a thread responsible # for ensuring that its own state is correct when it wakes, and relies # on a rigid protocol to make this easy; so long as you stick to the # protocol, POSIX conditions are easy to "get right": # # A) The thread that's waiting for some arbitrarily-complex condition # (ACC) to become true does: # # condition.acquire() # while not (code to evaluate the ACC): # condition.wait() # # That blocks the thread, *and* releases the lock. When a # # condition.signal() happens, it will wake up some thread that # # did a .wait, *and* acquire the lock again before .wait # # returns. # # # # Because the lock is acquired at this point, the state used # # in evaluating the ACC is frozen, so it's safe to go back & # # reevaluate the ACC. # # # At this point, ACC is true, and the thread has the condition # # locked. # # So code here can safely muck with the shared state that # # went into evaluating the ACC -- if it wants to. # # When done mucking with the shared state, do # condition.release() # # B) Threads that are mucking with shared state that may affect the # ACC do: # # condition.acquire() # # muck with shared state # condition.release() # if it's possible that ACC is true now: # condition.signal() # or .broadcast() # # Note: You may prefer to put the "if" clause before the release(). # That's fine, but do note that anyone waiting on the signal will # stay blocked until the release() is done (since acquiring the # condition is part of what .wait() does before it returns). # # TRICK OF THE TRADE # # With simpler forms of conditions, it can be impossible to know when # a thread that's supposed to do a .wait has actually done it. But # because this form of condition releases a lock as _part_ of doing a # wait, the state of that lock can be used to guarantee it. # # E.g., suppose thread A spawns thread B and later wants to wait for B to # complete: # # In A: In B: # # B_done = condition() ... do work ... # B_done.acquire() B_done.acquire(); B_done.release() # spawn B B_done.signal() # ... some time later ... ... and B exits ... # B_done.wait() # # Because B_done was in the acquire'd state at the time B was spawned, # B's attempt to acquire B_done can't succeed until A has done its # B_done.wait() (which releases B_done). So B's B_done.signal() is # guaranteed to be seen by the .wait(). Without the lock trick, B # may signal before A .waits, and then A would wait forever. # # BARRIERS # # A barrier object is created via # import this_module # your_barrier = this_module.barrier(num_threads) # # Methods: # .enter() # the thread blocks until num_threads threads in all have done # .enter(). Then the num_threads threads that .enter'ed resume, # and the barrier resets to capture the next num_threads threads # that .enter it. # # EVENTS # # An event object is created via # import this_module # your_event = this_module.event() # # An event has two states, `posted' and `cleared'. An event is # created in the cleared state. # # Methods: # # .post() # Put the event in the posted state, and resume all threads # .wait'ing on the event (if any). # # .clear() # Put the event in the cleared state. # # .is_posted() # Returns 0 if the event is in the cleared state, or 1 if the event # is in the posted state. # # .wait() # If the event is in the posted state, returns immediately. # If the event is in the cleared state, blocks the calling thread # until the event is .post'ed by another thread. # # Note that an event, once posted, remains posted until explicitly # cleared. Relative to conditions, this is both the strength & weakness # of events. It's a strength because the .post'ing thread doesn't have to # worry about whether the threads it's trying to communicate with have # already done a .wait (a condition .signal is seen only by threads that # do a .wait _prior_ to the .signal; a .signal does not persist). But # it's a weakness because .clear'ing an event is error-prone: it's easy # to mistakenly .clear an event before all the threads you intended to # see the event get around to .wait'ing on it. But so long as you don't # need to .clear an event, events are easy to use safely. # # SEMAPHORES # # A semaphore object is created via # import this_module # your_semaphore = this_module.semaphore(count=1) # # A semaphore has an integer count associated with it. The initial value # of the count is specified by the optional argument (which defaults to # 1) passed to the semaphore constructor. # # Methods: # # .p() # If the semaphore's count is greater than 0, decrements the count # by 1 and returns. # Else if the semaphore's count is 0, blocks the calling thread # until a subsequent .v() increases the count. When that happens, # the count will be decremented by 1 and the calling thread resumed. # # .v() # Increments the semaphore's count by 1, and wakes up a thread (if # any) blocked by a .p(). It's an (detected) error for a .v() to # increase the semaphore's count to a value larger than the initial # count. # # MULTIPLE-READER SINGLE-WRITER LOCKS # # A mrsw lock is created via # import this_module # your_mrsw_lock = this_module.mrsw() # # This kind of lock is often useful with complex shared data structures. # The object lets any number of "readers" proceed, so long as no thread # wishes to "write". When a (one or more) thread declares its intention # to "write" (e.g., to update a shared structure), all current readers # are allowed to finish, and then a writer gets exclusive access; all # other readers & writers are blocked until the current writer completes. # Finally, if some thread is waiting to write and another is waiting to # read, the writer takes precedence. # # Methods: # # .read_in() # If no thread is writing or waiting to write, returns immediately. # Else blocks until no thread is writing or waiting to write. So # long as some thread has completed a .read_in but not a .read_out, # writers are blocked. # # .read_out() # Use sometime after a .read_in to declare that the thread is done # reading. When all threads complete reading, a writer can proceed. # # .write_in() # If no thread is writing (has completed a .write_in, but hasn't yet # done a .write_out) or reading (similarly), returns immediately. # Else blocks the calling thread, and threads waiting to read, until # the current writer completes writing or all the current readers # complete reading; if then more than one thread is waiting to # write, one of them is allowed to proceed, but which one is not # specified. # # .write_out() # Use sometime after a .write_in to declare that the thread is done # writing. Then if some other thread is waiting to write, it's # allowed to proceed.

ioi@blue.seas.upenn.edu Ioi K. Lam at University of Pennsylvania Hi, I have implemented a new image type called "compound". It allows you to glue together a bunch of bitmaps, images and text strings together to form a bigger image. Then you can use this image with widgets that support the -image option. For example, you can display a text string string together with a bitmap, at the same time, inside a TK button widget. tdisabledtstatetexpanditfilltpadxitpadyitsideitoktOkt underlinetcommandtcanceltCancel(Rtexittwinfo_toplevelt wm_protocoltTixt LabelEntrytentrytinsertt PanedWindowtaddtScrolledListBoxtlistboxt ScrolledTextRtENDtpacktBOTHtTOPt ButtonBoxt HORIZONTALRtBOTTOMtX( Rtwtztgrouptpanetp1tp2RRtbox((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyt__init__sJ          %%(.  cCs d|_dS(Ni(R%(R((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyRVscCs-x&|jdkr(|jjjtqWdS(Ni(R%Rttkt dooneeventtTCL_ALL_EVENTS(R((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyRYscCs|jjdS(N(RR(R((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyR]s(t__name__t __module__R@RRR(((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyRs :  t__main__((R(RCRRRDtTkR(((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyts  E  PK%L]3U tix/samples/DirList.pycnu[ ^c@sddlZddlZddlZddlTdZdZdd dYZedkrddlZddl Z yej Z ee Wqe j \ZZZdZxAe jeeeD]&Zeed Zejd eZqWqXndS( iN(t*icCs$t|}|j|jdS(N(t DemoDirListtmainlooptdestroy(troottdirlist((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyt RunSamples  RcBs>eZdZdZdZdZdZdZRS(c Csc||_d|_|j}|jd|dtj|dtdd}tj||_d|jj d#ttrelieftbdii(twidthttexts >> tpadyitlabelsInstallation Directory:t labelsidettoptoptionss entry.width 40 label.anchor w stix option get fixed_fonttfontt textvariablecSs|j||S(N(t copy_name(tdirtentR ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyR KstcommandscSs |jS(N(tokcmd(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyR OR texpandtyestfilltbothtsidetpadxitanchortst orientationt horizontaltoktOkt underlineicSs |jS(N(R(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyR ZR tcanceltCancelcSs |jS(N(R(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyR \R tx(Rtexittwinfo_toplevelt wm_protocoltTixtFrametRAISEDtDirListRthlisttButtontbtnt LabelEntryRttktevaltentrytcopytostcurdirt dlist_dirtbindtpacktTOPtBOTHtLEFTtXt ButtonBoxtaddtBOTTOM(R twtzRRtbox((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyt__init__s6    +%1  cCs?|jd|_|jjdd|jjd|jdS(Ntvalueitend(tcgetR=R9tdeletetinsert(R RR((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyR`scCs|jdS(N(R(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyRgscCs d|_dS(Ni(R,(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyRkscCs-x&|jdkr(|jjjtqWdS(Ni(R,RR7t dooneeventtTCL_ALL_EVENTS(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyRnscCs|jjdS(N(RR(R ((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyRrs(t__name__t __module__RJRRRRR(((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyRs  B    t__main__sError running the demo script: s sTix Demo Error((R/R;R:t TkconstantsRQRRRRt tkMessageBoxt tracebacktTkRtsystexc_infotttvttbRtformat_exceptiontlinet showerrortd(((s0/usr/lib64/python2.7/Demo/tix/samples/DirList.pyts$  [  PK%L]ûT T tix/samples/ComboBox.pynu[# -*-mode: python; fill-column: 75; tab-width: 8; coding: iso-latin-1-unix -*- # # $Id$ # # Tix Demonstration Program # # This sample program is structured in such a way so that it can be # executed from the Tix demo program "tixwidgets.py": it must have a # procedure called "RunSample".

For example, you can display a text string string together with a bitmap, at the same time, inside a TK button widget. tdisabledtstatetexpanditfilltpadxitpadyitsideitoktOkt underlinetcommandtcanceltCancel(Rtexittwinfo_toplevelt wm_protocoltTixt LabelEntrytentrytinsertt PanedWindowtaddtScrolledListBoxtlistboxt ScrolledTextRtENDtpacktBOTHtTOPt ButtonBoxt HORIZONTALRtBOTTOMtX( Rtwtztgrouptpanetp1tp2RRtbox((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyt__init__sJ          %%(.  cCs d|_dS(Ni(R%(R((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyRVscCs-x&|jdkr(|jjjtqWdS(Ni(R%Rttkt dooneeventtTCL_ALL_EVENTS(R((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyRYscCs|jjdS(N(RR(R((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyR]s(t__name__t __module__R@RRR(((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyRs :  t__main__((R(RCRRRDtTkR(((s1/usr/lib64/python2.7/Demo/tix/samples/PanedWin.pyts  E  PK%L]Dl11tix/samples/CmpImg.pynu[# -*-mode: python; fill-column: 75; tab-width: 8; coding: iso-latin-1-unix -*- # # $Id$ # # Tix Demonstration Program # # This sample program is structured in such a way so that it can be # executed from the Tix demo program "tixwidgets.py": it must have a # procedure called "RunSample".

Tix widgets are an attractive and useful extension to Tk. See http://tix.sourceforge.net for more details about Tix and how to get it. Features: 1) It is almost complete. 2) Tix widgets are represented by classes in Python. Sub-widgets are members of the mega-widget class. For example, if a particular TixWidget (e.g. ScrolledText) has an embedded widget (Text in this case), it is possible to call the methods of the child directly. 3) The members of the class are created automatically. In the case of widgets like ButtonBox, the members are added dynamically. PK%L]䠵&& tix/grid.pynu[### import Tix as tk from pprint import pprint r= tk.Tk() r.title("test") l=tk.Label(r, name="a_label") l.pack() class MyGrid(tk.Grid): def __init__(self, *args, **kwargs): kwargs['editnotify']= self.editnotify tk.Grid.__init__(self, *args, **kwargs) def editnotify(self, x, y): return True g = MyGrid(r, name="a_grid", selectunit="cell") g.pack(fill=tk.BOTH) for x in xrange(5): for y in xrange(5): g.set(x,y,text=str((x,y))) c = tk.Button(r, text="Close", command=r.destroy) c.pack() tk.mainloop() PK%L]*ϰtix/INSTALL.txtnu[$Id$ Installing Tix.py ---------------- 0) To use Tix.py, you need Tcl/Tk (V8.3.3), Tix (V8.1.1) and Python (V2.1.1). Tix.py has been written and tested on an Intel Pentium running RH Linux 5.2 and Mandrake Linux 7.0 and Windows with the above mentioned packages. Older versions, e.g. Tix 4.1 and Tk 8.0, might also work. There is nothing OS-specific in Tix.py itself so it should work on any machine with Tix and Python installed. You can get Tcl and Tk from http://dev.scriptics.com and Tix from http://tix.sourceforge.net. 1) Build and install Tcl/Tk 8.3. Build and install Tix 8.1. Ensure that Tix is properly installed by running tixwish and executing the demo programs. Under Unix, use the --enable-shared configure option for all three. We recommend tcl8.3.3 for this release of Tix.py. 2a) If you have a distribution like ActiveState with a tcl subdirectory of $PYTHONHOME, which contains the directories tcl8.3 and tk8.3, make a directory tix8.1 as well. Recursively copy the files from /library to $PYTHONHOME/lib/tix8.1, and copy the dynamic library (tix8183.dll or libtix8.1.8.3.so) to the same place as the tcl dynamic libraries ($PYTHONHOME/Dlls or lib/python-2.1/lib-dynload). In this case you are all installed, and you can skip to the end. 2b) Modify Modules/Setup.dist and setup.py to change the version of the tix library from tix4.1.8.0 to tix8.1.8.3 These modified files can be used for Tkinter with or without Tix. 3) The default is to build dynamically, and use the Tcl 'package require'. To build statically, modify the Modules/Setup file to link in the Tix library according to the comments in the file. On Linux this looks like: # *** Always uncomment this (leave the leading underscore in!): _tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \ # *** Uncomment and edit to reflect where your Tcl/Tk libraries are: -L/usr/local/lib \ # *** Uncomment and edit to reflect where your Tcl/Tk headers are: -I/usr/local/include \ # *** Uncomment and edit to reflect where your X11 header files are: -I/usr/X11R6/include \ # *** Or uncomment this for Solaris: # -I/usr/openwin/include \ # *** Uncomment and edit for BLT extension only: # -DWITH_BLT -I/usr/local/blt/blt8.0-unoff/include -lBLT8.0 \ # *** Uncomment and edit for PIL (TkImaging) extension only: # (See http://www.pythonware.com/products/pil/ for more info) # -DWITH_PIL -I../Extensions/Imaging/libImaging tkImaging.c \ # *** Uncomment and edit for TOGL extension only: # -DWITH_TOGL togl.c \ # *** Uncomment and edit for Tix extension only: -DWITH_TIX -ltix8.1.8.3 \ # *** Uncomment and edit to reflect your Tcl/Tk versions: -ltk8.3 -ltcl8.3 \ # *** Uncomment and edit to reflect where your X11 libraries are: -L/usr/X11R6/lib \ # *** Or uncomment this for Solaris: # -L/usr/openwin/lib \ # *** Uncomment these for TOGL extension only: # -lGL -lGLU -lXext -lXmu \ # *** Uncomment for AIX: # -lld \ # *** Always uncomment this; X11 libraries to link with: -lX11 4) Rebuild Python and reinstall. You should now have a working Tix implementation in Python. To see if all is as it should be, run the 'tixwidgets.py' script in the Demo/tix directory. Under X windows, do /usr/local/bin/python Demo/tix/tixwidgets.py If this does not work, you may need to tell python where to find the Tcl, Tk and Tix library files. This is done by setting the TCL_LIBRARY, TK_LIBRARY and TIX_LIBRARY environment variables. Try this: env TCL_LIBRARY=/usr/local/lib/tcl8.3 \ TK_LIBRARY=/usr/local/lib/tk8.3 \ TIX_LIBRARY=/usr/local/lib/tix8.1 \ /usr/local/bin/python Demo/tix/tixwidgets.py If you find any bugs or have suggestions for improvement, please report them via http://tix.sourceforge.net PK%L]Irscripts/makedir.pynuȯ#! /usr/bin/python2.7 # Like mkdir, but also make intermediate directories if necessary. # It is not an error if the given directory already exists (as long # as it is a directory). # Errors are not treated specially -- you just get a Python exception. import sys, os def main(): for p in sys.argv[1:]: makedirs(p) def makedirs(p): if p and not os.path.isdir(p): head, tail = os.path.split(p) makedirs(head) os.mkdir(p, 0777) if __name__ == "__main__": main() PK%L]u=iiscripts/from.pynuȯ#! /usr/bin/python2.7 # Print From and Subject of messages in $MAIL. # Extension to multiple mailboxes and other bells & whistles are left # as exercises for the reader. import sys, os # Open mailbox file.

Separate versions (one optimized for speed, one for beauty :-) are ok. Post your code so we can time it on our own systems. 0) Factorial Test (numerics and function calls) (we did this already) 1) Regular Expressions Test Read a file of (extended per egrep) regular expressions (one per line), and apply those to all files whose names are listed on the command line. Basically, an 'egrep -f' simulator. Test it with 20 "vt100" patterns against a five /etc/termcap files. Tests using more elaborate patters would also be interesting. Your code should not break if given hundreds of regular expressions or binary files to scan. 2) Sorting Test Sort an input file that consists of lines like this var1=23 other=14 ditto=23 fred=2 such that each output line is sorted WRT to the number. Order of output lines does not change. Resolve collisions using the variable name. e.g. fred=2 other=14 ditto=23 var1=23 Lines may be up to several kilobytes in length and contain zillions of variables. 3) System Test Given a list of directories, report any bogus symbolic links contained anywhere in those subtrees. A bogus symbolic link is one that cannot be resolved because it points to a nonexistent or otherwise unresolvable file. Do *not* use an external find executable. Directories may be very very deep. Print a warning immediately if the system you're running on doesn't support symbolic links.

The Server class is instantiated with a port number on which it should listen for requests; the Client class is instantiated with a host name and a port number where it should connect to. Once a client is connected, a TCP connection is maintained between client and server. The Server class currently handles only one connection at a time; however it could be rewritten to allow various modes of operations, using multiple threads or processes or the select() system call as desired to serve multiple clients simultaneously (when using select(), still handling one request at a time). This would not require rewriting of the Client class. It may also be possible to adapt the code to use UDP instead of TCP, but then both classes will have to be rewritten (and unless extensive acknowlegements and request serial numbers are used, the server should handle duplicate requests, so its semantics should be idempotent -- shrudder). Even though the FSProxy and RCSProxy modules define client classes, the client class is fully generic -- what methods it supports is determined entirely by the server. The server class, however, must be derived from. This is generally done as follows: from server import Server from client import Client # Define a class that performs the operations locally class MyClassLocal: def __init__(self): ... def _close(self): ... # Derive a server class using multiple inheritance class MyClassServer(MyClassLocal, Server): def __init__(self, address): # Must initialize MyClassLocal as well as Server MyClassLocal.__init__(self) Server.__init__(self, address) def _close(self): Server._close() MyClassLocal._close() # A dummy client class class MyClassClient(Client): pass Note that because MyClassLocal isn't used in the definition of MyClassClient, it would actually be better to place it in a separate module so the definition of MyClassLocal isn't executed when we only instantiate a client. The modules client and server should probably be renamed to Client and Server in order to match the class names. *** Security warning: this version requires that you have a file $HOME/.python_keyfile at the server and client side containing two comma- separated numbers. The security system at the moment makes no guarantees of actuallng being secure -- however it requires that the key file exists and contains the same numbers at both ends for this to work. (You can specify an alternative keyfile in $PYTHON_KEYFILE). Have a look at the Security class in security.py for details; basically, if the key file contains (x, y), then the security server class chooses a random number z (the challenge) in the range 10..100000 and the client must be able to produce pow(z, x, y) (i.e. z**x mod y).

CVS locking strategy ==================== As reverse engineered from the CVS 1.3 sources (file lock.c): - Locking is done on a per repository basis (but a process can hold write locks for multiple directories); all lock files are placed in the repository and have names beginning with "#cvs.". - Before even attempting to lock, a file "#cvs.tfl." is created (and removed again), to test that we can write the repository. [The algorithm can still be fooled (1) if the repository's mode is changed while attempting to lock; (2) if this file exists and is writable but the directory is not.] - While creating the actual read/write lock files (which may exist for a long time), a "meta-lock" is held. The meta-lock is a directory named "#cvs.lock" in the repository. The meta-lock is also held while a write lock is held. - To set a read lock: - acquire the meta-lock - create the file "#cvs.rfl." - release the meta-lock - To set a write lock: - acquire the meta-lock - check that there are no files called "#cvs.rfl.*" - if there are, release the meta-lock, sleep, try again - create the file "#cvs.wfl." - To release a write lock: - remove the file "#cvs.wfl." - rmdir the meta-lock - To release a read lock: - remove the file "#cvs.rfl." Additional notes ---------------- - A process should read-lock at most one repository at a time. - A process may write-lock as many repositories as it wishes (to avoid deadlocks, I presume it should always lock them top-down in the directory hierarchy). - A process should make sure it removes all its lock files and directories when it crashes. - Limitation: one user id should not be committing files into the same repository at the same time. Turn this into Python code -------------------------- rl = ReadLock(repository, waittime) wl = WriteLock(repository, waittime) list = MultipleWriteLock([repository1, repository2, ...], waittime) iNi is#cvs.lcks #cvs.rfl.s #cvs.wfl.tErrorcBs#eZdZdZdZRS(cCs ||_dS(N(tmsg(tselfR((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyt__init__`scCs t|jS(N(treprR(R((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyt__repr__cscCs t|jS(N(tstrR(R((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyt__str__fs(t__name__t __module__RRR(((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR^s  tLockedcBseZRS((RR (((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR jstLockcBsVeZdedZdZdZdZdZdZdZ dZ RS( t.cCsx||_||_d|_d|_ttj}|jt |_ |jt ||_ |jt ||_dS(N(t repositorytdelaytNonetlockdirtlockfileRtostgetpidtjointCVSLCKtcvslcktCVSRFLtcvsrfltCVSWFLtcvswfl(RR Rtpid((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyRps    cCsdGH|jdS(Nt__del__(tunlock(R((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyRzscCsxy'|j|_tj|jddSWqtjk r}d|_|dtkrytj|j}Wntjk rqnX|j|qnt d|j |fqXqWdS(Niisfailed to lock %s: %s( RRRtmkdirterrorRtEEXISTtstattsleepRR (RRtst((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyt setlockdir~s    cCs|j|jdS(N(t unlockfilet unlockdir(R((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyRs cCsP|jrLdG|jGHytj|jWntjk r?nXd|_ndS(Ntunlink(RRR'RR(R((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR%s  cCsP|jrLdG|jGHytj|jWntjk r?nXd|_ndS(Ntrmdir(RRR(RR(R((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR&s  cCst||j|jdS(N(R"R R(RR#((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR"scCstjj|j|S(N(RtpathRR (Rtname((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyRs( RR tDELAYRRR$RR%R&R"R(((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR ns    cCs|dkrt|n|tj}ytj|}|d}Wntk rbd|}nXdtjtjdd!Gd|G|GHtj|dS(Nisuid %ds[%s]i isWaiting for %s's lock in( R R!tST_UIDtpwdtgetpwuidtKeyErrorttimetctimeR"(R#R Rtuidtpwenttuser((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR"s    tReadLockcBseZedZRS(cCsztj|||d}z<|j|j|_t|jd}|jd}Wd|sk|jn|jXdS(Nitwi( R RR$RRtopentcloseR%R&(RR Rtoktfp((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyRs     (RR R+R(((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR5st WriteLockcBseZedZdZRS(cCs}tj||||jx1|j}|s6Pn|j|j|q W|j|_t|jd}|j dS(NR6( R RR$t readers_existR&R"RRR7R8(RR RR2R:((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyRs    cCswtt}xdtj|jD]P}|| tkrytj|j|}Wntjk rjqnX|SqWdS(N( tlenRRtlistdirR R!RRR(RtnR*R#((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR<s (RR R+RR<(((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyR;s cCsjxcg}xC|D]:}y|jt|dWqtk rI}~PqXqWPt|j||qWtS(Ni(tappendR;R R"Rtlist(t repositoriesRtlockstrtinstance((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pytMultipleWriteLocks  cCsddl}|jdr)|jd}nd}d}d}zDdGHt|}dGH|jdGHt|}dGH|jWddgGHd|_dgGH|r|jndgGH|r|jnd gGHd}d gGHd}d gGHXdS( NiiR sattempting write lock ...sgot it.sattempting read lock ...iiiii(tsystargvRR;RR5t exc_traceback(RGR trltwl((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pyttests8        t__main__(((t__doc__RR0R!R-R+R RRRRR R R"R5R;RFRLR(((s*/usr/lib64/python2.7/Demo/pdist/cvslock.pytGs&     ?   !

CVS locking strategy ==================== As reverse engineered from the CVS 1.3 sources (file lock.c): - Locking is done on a per repository basis (but a process can hold write locks for multiple directories); all lock files are placed in the repository and have names beginning with "#cvs.". - Before even attempting to lock, a file "#cvs.tfl." is created (and removed again), to test that we can write the repository. [The algorithm can still be fooled (1) if the repository's mode is changed while attempting to lock; (2) if this file exists and is writable but the directory is not.] - While creating the actual read/write lock files (which may exist for a long time), a "meta-lock" is held. The meta-lock is a directory named "#cvs.lock" in the repository. The meta-lock is also held while a write lock is held. - To set a read lock: - acquire the meta-lock - create the file "#cvs.rfl." - release the meta-lock - To set a write lock: - acquire the meta-lock - check that there are no files called "#cvs.rfl.*" - if there are, release the meta-lock, sleep, try again - create the file "#cvs.wfl." - To release a write lock: - remove the file "#cvs.wfl." - rmdir the meta-lock - To release a read lock: - remove the file "#cvs.rfl." Additional notes ---------------- - A process should read-lock at most one repository at a time. - A process may write-lock as many repositories as it wishes (to avoid deadlocks, I presume it should always lock them top-down in the directory hierarchy). - A process should make sure it removes all its lock files and directories when it crashes. - Limitation: one user id should not be committing files into the same repository at the same time.

CVS locking strategy ==================== As reverse engineered from the CVS 1.3 sources (file lock.c): - Locking is done on a per repository basis (but a process can hold write locks for multiple directories); all lock files are placed in the repository and have names beginning with "#cvs.". - Before even attempting to lock, a file "#cvs.tfl." is created (and removed again), to test that we can write the repository. [The algorithm can still be fooled (1) if the repository's mode is changed while attempting to lock; (2) if this file exists and is writable but the directory is not.] - While creating the actual read/write lock files (which may exist for a long time), a "meta-lock" is held. The meta-lock is a directory named "#cvs.lock" in the repository. The meta-lock is also held while a write lock is held. - To set a read lock: - acquire the meta-lock - create the file "#cvs.rfl." - release the meta-lock - To set a write lock: - acquire the meta-lock - check that there are no files called "#cvs.rfl.*" - if there are, release the meta-lock, sleep, try again - create the file "#cvs.wfl." - To release a write lock: - remove the file "#cvs.wfl." - rmdir the meta-lock - To release a read lock: - remove the file "#cvs.rfl." Additional notes ---------------- - A process should read-lock at most one repository at a time. - A process may write-lock as many repositories as it wishes (to avoid deadlocks, I presume it should always lock them top-down in the directory hierarchy). - A process should make sure it removes all its lock files and directories when it crashes. - Limitation: one user id should not be committing files into the same repository at the same time.
