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 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 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

    - -

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! - Now you know everything about meta-classes and the Real-World! - - - --- - Vladimir MARANGOZOV | Vladimir.Marangozov@inrialpes.fr -http://sirac.inrialpes.fr/~marangoz | tel:(+33-4)76615277 fax:76615252 diff --git a/Demo/parser/FILES b/Demo/parser/FILES deleted file mode 100644 index 1ff59a31a2..0000000000 --- a/Demo/parser/FILES +++ /dev/null @@ -1,6 +0,0 @@ -Demo/parser -Doc/libparser.tex -Lib/AST.py -Lib/symbol.py -Lib/token.py -Modules/parsermodule.c diff --git a/Demo/parser/README b/Demo/parser/README deleted file mode 100644 index f2f18cade5..0000000000 --- a/Demo/parser/README +++ /dev/null @@ -1,25 +0,0 @@ -These files are from the large example of using the `parser' module.

With -g you specify -a shell command to be executed to sound the gong; with -G you can -specify the interval between gong calls, in seconds (default is one hour). -The shell command is executed in the background. It is given two -arguments: the hours (on a 24 hour clock!) and the minutes. The -executable Python script /ufs/guido/bin/sgi/chime is a suitable example. -Again, this only works if you have installed a speaker (I bet 8 ohm -speakers are going to be in demand!) - --- -Guido van Rossum, Centre for Mathematics and Computer Science (CWI), Amsterdam -guido@cwi.nl or ..!hp4nl!cwi.nl!guido or guido%cwi.nl@uunet.uu.net -"A thing of beauty is a joy till sunrise" diff --git a/Demo/sgi/gl/mclock.py b/Demo/sgi/gl/mclock.py deleted file mode 100755 index 6af01ba991..0000000000 --- a/Demo/sgi/gl/mclock.py +++ /dev/null @@ -1,736 +0,0 @@ -#! /usr/bin/env python -

The format consists of -a header containing global information (like data format) -followed by a sequence of frames, each consisting of a header -followed by the actual frame data. -All information except pixel data is -encoded in ASCII. Pixel data is \fIalways\fP encoded in Silicon Graphics -order, which means that the first pixel in the frame is the lower left -pixel on the screen. -.PP -All ASCII data except the first line of the file -is in python format. This means that -outer parentheses can be ommitted, and parentheses around a tuple with -one element can also be omitted. So, the lines -.IP -.ft C -.nf -('grey',(4)) -('grey',4) -'grey',4 -.LP -have the same meaning. -To ease parsing in C programs, however, it is advised that there are -no parenteses around single items, and that there are parentheses around -lists. So, the second format above is preferred. -.PP -The current version is version 3, but this document will also explain -shortly what the previous formats looked like. -.SH -Header. -.PP -The header consists of three lines. The first line identifies the file -as a CMIF video file, and gives the version number. -It looks as follows: -.IP -.ft C -CMIF video 3.0 -.LP -All programs expect the layout to be exactly like this, so no -extra spaces, etc. should be added. -.PP -The second line specifies the data format. Its format is a python -tuple with two members. The first member is a string giving the format -type and the second is a tuple containing type-specific information. -The following formats are currently understood: -.pT rgb -The video data is 24 bit RGB packed into 32 bit words. -R is the least significant byte, then G and then B. The top byte is -unused. -.IP -There is no type-specific information, so the complete data format -line is -.IP -.ft C -('rgb',()) -.pT grey -The video data is greyscale, at most 8 bits. Data is packed into -8 bit bytes (in the low-order bits). The extra information is the -number of significant bits, so an example data format line is -.IP -.ft C -('grey',(6)) -.pT yiq -The video data is in YIQ format. This is a format that has one luminance -component, Y, and two chrominance components, I and Q. The luminance and -chrominance components are encoded in \fItwo\fP pixel arrays: first an -array of 8-bit luminance values followed by a array of 16 bit chrominance -values. See the section on chrominance coding for details. -.IP -The type specific part contains the number of bits for Y, I and Q, -the chrominance packfactor and the colormap offset. So, a sample format -information line of -.IP -.ft C -('yiq',(5,3,3,2,1024)) -.IP -means that the pictures have 5 bit Y values (in the luminance array), -3 bits of I and Q each (in the chrominance array), chrominance data -is packed for 2x2 pixels, and the first colormap index used is 1024. -.pT hls -The video data is in HLS format. L is the luminance component, H and S -are the chrominance components. The data format and type specific information -are the same as for the yiq format. -.pT hsv -The video data is in HSV format. V is the luminance component, H and S -are the chrominance components. Again, data format and type specific -information are the same as for the yiq format. -.pT rgb8 -The video data is in 8 bit dithered rgb format. This is the format -used internally by the Indigo. bit 0-2 are green, bit 3-4 are blue and -bit 5-7 are red. Because rgb8 is treated more-or-less like yiq format -internally the type-specific information is the same, with zeroes for -the (unused) chrominance sizes: -.IP -.ft C -('rgb8',(8,0,0,0,0)) -.PP -The third header line contains width and height of the video image, -in pixels, and the pack factor of the picture. For compatability, RGB -images must have a pack factor of 0 (zero), and non-RGB images must -have a pack factor of at least 1. -The packfactor is the amount of compression done on the original video -signal to obtain pictures. In other words, if only one out of three pixels -and lines is stored (so every 9 original pixels have one pixel in the -data) the packfactor is three. Width and height are the size of the -\fIoriginal\fP picture. -Viewers are expected to enlarge the picture so it is shown in the -original size. RGB videos cannot be packed. -So, a size line like -.IP -.ft C -200,200,2 -.LP -means that this was a 200x200 picture that is stored as 100x100 pixels. -.SH -Frame header -.PP -Each frame is preceded by a single header line. This line contains timing information -and optional size information. The time information is mandatory, and -contains the time this frame should be displayed, in milliseconds since -the start of the film. Frames should be stored in chronological order. -.PP -An optional second number is interpreted as the size of the luminance -data in bytes. Currently this number, if present, should always be the -same as \fCwidth*height/(packfactor*packfactor)\fP (times 4 for RGB -data), but this might change if we come up with variable-length encoding -for frame data. -.PP -An optional third number is the size of the chrominance data -in bytes. If present, the number should be equal to -.ft C -luminance_size2*/(chrompack*chrompack). -.SH -Frame data -.PP -For RGB films, the frame data is an array of 32 bit pixels containing -RGB data in the lower 24 bits. For greyscale films, the frame data -is an array of 8 bit pixels. For split luminance/chrominance films the -data consists of two parts: first an array of 8 bit luminance values -followed by an array of 16 bit chrominance values. -.PP -For all data formats, the data is stored left-to-right, bottom-to-top. -.SH -Chrominance coding -.PP -Since the human eye is apparently more sensitive to luminance changes -than to chrominance changes we support a coding where we split the luminance -and chrominance components of the video image. The main point of this -is that it allows us to transmit chrominance data in a coarser granularity -than luminance data, for instance one chrominance pixel for every -2x2 luminance pixels. According to the theory this should result in an -acceptable picture while reducing the data by a fair amount. -.PP -The coding of split chrominance/luminance data is a bit tricky, to -make maximum use of the graphics hardware on the Personal Iris.

All the tools mentioned currently live in /ufs/guido/bin/sgi. -A description of the CMIF video file format can be found in -/ufs/jack/cmif-film.ms. - - Recording video - -There are two tools to record video, Vrec and and Vrecb. Vrec does -continuous capture, but can capture at most 15 frames per second. -Vrecb uses burst capture, enabling it to capture all frames. It -captures to main memory, however, so it cannot handle long video -fragments. The following options are common to both programs: - - -r rate Capture one out of 'rate' frames. Default (and - minimum) is 1 for Vrecb, 2 for Vrec. There are some - caveats for recording PAL, see below. - -w width Set initial window width (and height, implicitly). - -g bits Create greyscale film in stead of 8-bit dithered color - film. Allowable values for 'bits' are 2, 4 or 8. - -m Create monochrome dithered film. These look horrible. - -M threshold Create monochrome thresholded film with specified - threshold (in range 0..255). - -G Create 2-bit dithered greyscale film. - -f Capture fields in stead of frames. The film is created - in such a way that the picture will be suitably - enlarged on playback, so aspect ratio, etc. are - maintained. - -d Drop fields if they would cause data from two video - fields to be combined. See the section on PAL for more - details. - -Options for Vrec: - -a Record audio as well. You will have to twiddle audio - and video later if you want lipsync playback. - -q queuesize Set size of the video board circular buffer. A little - experimentation with this may lead to more video being - captured, but not always. - -P frames Preallocate diskspace for 'frames' images. This may - enable you to capture more frames. - -Options for Vrecb: - -n number Capture 'number' frames. Default is 60 (2 seconds). - -Both programs accept a filename to store the video on (default -film.video) and Vrec also accepts an audio file name (default -film.aiff). When you want to record you press the left mouse button. -Vrec stops recording when you release the mouse button and Vrecb stops -after the predetermined number of frames have been recorded. During -recording the picture may look funny, but do not let this worry you, -the film will be ok. - -After recording and saving, Vrec will print the deltas of the field -numbers recorded. A list of '4 4 4 4'... means that all possible -frames (one out of two) have been recorded. Vrecb will tell you how -many duplicate fields have been skipped. See below on PAL useage -again. - - PAL caveats - -The IndigoVideo board converts the incoming video signal to the 60Hz -(59.something, actually) display rate. All further operations, -including capture, are done with respect to display rate. This is -especially bothersome in the case of PAL video, since it means one out -of 5 frames will be duplicated. Together with the fact that, in -continuous capture, you can only capture every second frame this leads -to strange and wondrous effects. The frame numbers returned by the -video board (and displayed by Vrec) are display frame numbers, and so -bear only a very complicated (and probably non-deterministic) relation -to PAL frame numbers. For recording simple videos this is probably no -problem. You can use Vrec and try using -d to see which gives the best -result. On the other hand, if you need every frame and no duplicates -either you have to use Vrecb and supply the -d and -f option. This -will give you exactly the fields as they appeared on the PAL tape. - - Video playback - -The easiest way to play back a video is to use Vplay. Calling it with -an argument of -? will make it list all its options. A few options may -need a bit of explanation: - -M magnify Magnify the images by the given factor. This still - takes any magnification specified in the film (if it - is a field film, for instance) in account. - -w width and - -h height Normally the window will be the correct size for the - film. You can set height and width, though, if you - want the window to be bigger. This is especially - useful if you want to record the film back to - videotape, since you can playback in a window that is - bigger than PAL size with a black background and you - will have no distracting window-manager thingies on - your videotape. - - Video Editing - -Vedit is a (very simple) video editor that allows you to select images -from the input movie and copy them to an output movie. Both input and -output films have a modest buffer that you can move around in. - -Vaddcache takes a movie and adds a frame location cache to it. This -will make some other programs run faster. - -rgb2video converts a set of SGI .rgb files to a movie. - -There are a few programs that can do image format conversion on movies -(i.e. convert an 8-bit dithered RGB movie to a greyscale movie), but -nothing very complete yet.

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.
