Search the directories pointed to by the preprocessor variables - PREFIX and EXEC_PREFIX. These paths are prefixed with the volume name - extracted from argv0_path. The volume names correspond to the UEFI - shell "map" names. - - That's it! - - Well, almost. Once we have determined prefix and exec_prefix, the - preprocessor variable PYTHONPATH is used to construct a path. Each - relative path on PYTHONPATH is prefixed with prefix. Then the directory - containing the shared library modules is appended. The environment - variable $PYTHONPATH is inserted in front of it all.

A Python long with that much space is reserved -near the start, and the result is computed into it. - -The input string is actually treated as being in base base**i (i.e., i digits -are processed at a time), where two more static arrays hold: - - convwidth_base[base] = the largest integer i such that - base**i <= PyLong_BASE - convmultmax_base[base] = base ** convwidth_base[base] - -The first of these is the largest i such that i consecutive input digits -must fit in a single Python digit. The second is effectively the input -base we're really using. - -Viewing the input as a sequence of digits in base -convmultmax_base[base], the result is "simply" - - (((c0*B + c1)*B + c2)*B + c3)*B + ... ))) + c_n-1 - -where B = convmultmax_base[base]. - -Error analysis: as above, the number of Python digits `n` needed is worst- -case - - n >= N * log(B)/log(PyLong_BASE) - -where `N` is the number of input digits in base `B`. This is computed via - - size_z = (Py_ssize_t)((scan - str) * log_base_PyLong_BASE[base]) + 1; - -below. Two numeric concerns are how much space this can waste, and whether -the computed result can be too small. To be concrete, assume PyLong_BASE = -2**15, which is the default (and it's unlikely anyone changes that). - -Waste isn't a problem: provided the first input digit isn't 0, the difference -between the worst-case input with N digits and the smallest input with N -digits is about a factor of B, but B is small compared to PyLong_BASE so at -most one allocated Python digit can remain unused on that count. If -N*log(B)/log(PyLong_BASE) is mathematically an exact integer, then truncating -that and adding 1 returns a result 1 larger than necessary. However, that -can't happen: whenever B is a power of 2, long_from_binary_base() is called -instead, and it's impossible for B**i to be an integer power of 2**15 when B -is not a power of 2 (i.e., it's impossible for N*log(B)/log(PyLong_BASE) to be -an exact integer when B is not a power of 2, since B**i has a prime factor -other than 2 in that case, but (2**15)**j's only prime factor is 2). - -The computed result can be too small if the true value of -N*log(B)/log(PyLong_BASE) is a little bit larger than an exact integer, but -due to roundoff errors (in computing log(B), log(PyLong_BASE), their quotient, -and/or multiplying that by N) yields a numeric result a little less than that -integer. Unfortunately, "how close can a transcendental function get to an -integer over some range?" questions are generally theoretically intractable. -Computer analysis via continued fractions is practical: expand -log(B)/log(PyLong_BASE) via continued fractions, giving a sequence i/j of "the -best" rational approximations. Then j*log(B)/log(PyLong_BASE) is -approximately equal to (the integer) i. This shows that we can get very close -to being in trouble, but very rarely. For example, 76573 is a denominator in -one of the continued-fraction approximations to log(10)/log(2**15), and -indeed: - - >>> log(10)/log(2**15)*76573 - 16958.000000654003 - -is very close to an integer. If we were working with IEEE single-precision, -rounding errors could kill us. Finding worst cases in IEEE double-precision -requires better-than-double-precision log() functions, and Tim didn't bother. -Instead the code checks to see whether the allocated space is enough as each -new Python digit is added, and copies the whole thing to a larger long if not. -This should happen extremely rarely, and in fact I don't have a test case -that triggers it(!). Instead the code was tested by artificially allocating -just 1 digit at the start, so that the copying code was exercised for every -digit beyond the first. -***/ - register twodigits c; /* current input character */ - Py_ssize_t size_z; - int i; - int convwidth; - twodigits convmultmax, convmult; - digit *pz, *pzstop; - char* scan; - - static double log_base_PyLong_BASE[37] = {0.0e0,}; - static int convwidth_base[37] = {0,}; - static twodigits convmultmax_base[37] = {0,}; - - if (log_base_PyLong_BASE[base] == 0.0) { - twodigits convmax = base; - int i = 1; - - log_base_PyLong_BASE[base] = (log((double)base) / - log((double)PyLong_BASE)); - for (;;) { - twodigits next = convmax * base; - if (next > PyLong_BASE) - break; - convmax = next; - ++i; - } - convmultmax_base[base] = convmax; - assert(i > 0); - convwidth_base[base] = i; - } - - /* Find length of the string of numeric characters. */ - scan = str; - while (_PyLong_DigitValue[Py_CHARMASK(*scan)] < base) - ++scan; - - /* Create a long object that can contain the largest possible - * integer with this base and length.

Writing a_bits and b_bits for the - number of significant bits in a and b respectively, a - straightforward formula for shift is: - - shift = a_bits - b_bits - DBL_MANT_DIG - 2 - - This is fine in the usual case, but if a/b is smaller than the - smallest normal float then it can lead to double rounding on an - IEEE 754 platform, giving incorrectly rounded results. So we - adjust the formula slightly. The actual formula used is: - - shift = MAX(a_bits - b_bits, DBL_MIN_EXP) - DBL_MANT_DIG - 2 - - 2. The quantity x is computed by first shifting a (left -shift bits - if shift <= 0, right shift bits if shift > 0) and then dividing by - b. For both the shift and the division, we keep track of whether - the result is inexact, in a flag 'inexact'; this information is - needed at the rounding stage. - - With the choice of shift above, together with our assumption that - a_bits - b_bits >= DBL_MIN_EXP - DBL_MANT_DIG - 1, it follows - that x >= 1. - - 3. Now x * 2**shift <= a/b < (x+1) * 2**shift. We want to replace - this with an exactly representable float of the form - - round(x/2**extra_bits) * 2**(extra_bits+shift). - - For float representability, we need x/2**extra_bits < - 2**DBL_MANT_DIG and extra_bits + shift >= DBL_MIN_EXP - - DBL_MANT_DIG. This translates to the condition: - - extra_bits >= MAX(x_bits, DBL_MIN_EXP - shift) - DBL_MANT_DIG - - To round, we just modify the bottom digit of x in-place; this can - end up giving a digit with value > PyLONG_MASK, but that's not a - problem since digits can hold values up to 2*PyLONG_MASK+1. - - With the original choices for shift above, extra_bits will always - be 2 or 3. Then rounding under the round-half-to-even rule, we - round up iff the most significant of the extra bits is 1, and - either: (a) the computation of x in step 2 had an inexact result, - or (b) at least one other of the extra bits is 1, or (c) the least - significant bit of x (above those to be rounded) is 1. - - 4. Conversion to a double is straightforward; all floating-point - operations involved in the conversion are exact, so there's no - danger of rounding errors. - - 5. Use ldexp(x, shift) to compute x*2**shift, the final result. - The result will always be exactly representable as a double, except - in the case that it overflows. To avoid dependence on the exact - behaviour of ldexp on overflow, we check for overflow before - applying ldexp. The result of ldexp is adjusted for sign before - returning. - */ - - /* Reduce to case where a and b are both positive. */ - a_size = ABS(Py_SIZE(a)); - b_size = ABS(Py_SIZE(b)); - negate = (Py_SIZE(a) < 0) ^ (Py_SIZE(b) < 0); - if (b_size == 0) { - PyErr_SetString(PyExc_ZeroDivisionError, - "division by zero"); - goto error; - } - if (a_size == 0) - goto underflow_or_zero; - - /* Fast path for a and b small (exactly representable in a double). - Relies on floating-point division being correctly rounded; results - may be subject to double rounding on x86 machines that operate with - the x87 FPU set to 64-bit precision. */ - a_is_small = a_size <= MANT_DIG_DIGITS || - (a_size == MANT_DIG_DIGITS+1 && - a->ob_digit[MANT_DIG_DIGITS] >> MANT_DIG_BITS == 0); - b_is_small = b_size <= MANT_DIG_DIGITS || - (b_size == MANT_DIG_DIGITS+1 && - b->ob_digit[MANT_DIG_DIGITS] >> MANT_DIG_BITS == 0); - if (a_is_small && b_is_small) { - double da, db; - da = a->ob_digit[--a_size]; - while (a_size > 0) - da = da * PyLong_BASE + a->ob_digit[--a_size]; - db = b->ob_digit[--b_size]; - while (b_size > 0) - db = db * PyLong_BASE + b->ob_digit[--b_size]; - result = da / db; - goto success; - } - - /* Catch obvious cases of underflow and overflow */ - diff = a_size - b_size; - if (diff > PY_SSIZE_T_MAX/PyLong_SHIFT - 1) - /* Extreme overflow */ - goto overflow; - else if (diff < 1 - PY_SSIZE_T_MAX/PyLong_SHIFT) - /* Extreme underflow */ - goto underflow_or_zero; - /* Next line is now safe from overflowing a Py_ssize_t */ - diff = diff * PyLong_SHIFT + bits_in_digit(a->ob_digit[a_size - 1]) - - bits_in_digit(b->ob_digit[b_size - 1]); - /* Now diff = a_bits - b_bits. */ - if (diff > DBL_MAX_EXP) - goto overflow; - else if (diff < DBL_MIN_EXP - DBL_MANT_DIG - 1) - goto underflow_or_zero; - - /* Choose value for shift; see comments for step 1 above. */ - shift = MAX(diff, DBL_MIN_EXP) - DBL_MANT_DIG - 2; - - inexact = 0; - - /* x = abs(a * 2**-shift) */ - if (shift <= 0) { - Py_ssize_t i, shift_digits = -shift / PyLong_SHIFT; - digit rem; - /* x = a << -shift */ - if (a_size >= PY_SSIZE_T_MAX - 1 - shift_digits) { - /* In practice, it's probably impossible to end up - here.

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

-        """Create a new instance."""
-        return Instance(self)
-

-        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

    - -

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! - 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/AppPkg/Applications/Python/Python-2.7.2/Demo/newmetaclasses/Eiffel.py b/AppPkg/Applications/Python/Python-2.7.2/Demo/newmetaclasses/Eiffel.py deleted file mode 100644 index f3a412b..0000000 --- a/AppPkg/Applications/Python/Python-2.7.2/Demo/newmetaclasses/Eiffel.py +++ /dev/null @@ -1,141 +0,0 @@ -"""Support Eiffel-style preconditions and postconditions.""" - -from types import FunctionType as function - -class EiffelBaseMetaClass(type): - - def __new__(meta, name, bases, dict): - meta.convert_methods(dict) - return super(EiffelBaseMetaClass, meta).__new__(meta, name, bases, - dict) - - @classmethod - def convert_methods(cls, dict): - """Replace functions in dict with EiffelMethod wrappers. - - The dict is modified in place. - - If a method ends in _pre or _post, it is removed from the dict - regardless of whether there is a corresponding method. - """ - # find methods with pre or post conditions - methods = [] - for k, v in dict.iteritems(): - if k.endswith('_pre') or k.endswith('_post'): - assert isinstance(v, function) - elif isinstance(v, function): - methods.append(k) - for m in methods: - pre = dict.get("%s_pre" % m) - post = dict.get("%s_post" % m) - if pre or post: - dict[k] = cls.make_eiffel_method(dict[m], pre, post) - -class EiffelMetaClass1(EiffelBaseMetaClass): - # an implementation of the "eiffel" meta class that uses nested functions - - @staticmethod - def make_eiffel_method(func, pre, post): - def method(self, *args, **kwargs): - if pre: - pre(self, *args, **kwargs) - x = func(self, *args, **kwargs) - if post: - post(self, x, *args, **kwargs) - return x - - if func.__doc__: - method.__doc__ = func.__doc__ - - return method - -class EiffelMethodWrapper: - - def __init__(self, inst, descr): - self._inst = inst - self._descr = descr - - def __call__(self, *args, **kwargs): - return self._descr.callmethod(self._inst, args, kwargs) - -class EiffelDescriptor(object): - - def __init__(self, func, pre, post): - self._func = func - self._pre = pre - self._post = post - - self.__name__ = func.__name__ - self.__doc__ = func.__doc__ - - def __get__(self, obj, cls): - return EiffelMethodWrapper(obj, self) - - def callmethod(self, inst, args, kwargs): - if self._pre: - self._pre(inst, *args, **kwargs) - x = self._func(inst, *args, **kwargs) - if self._post: - self._post(inst, x, *args, **kwargs) - return x - -class EiffelMetaClass2(EiffelBaseMetaClass): - # an implementation of the "eiffel" meta class that uses descriptors - - make_eiffel_method = EiffelDescriptor - -def _test(metaclass): - class Eiffel: - __metaclass__ = metaclass - - class Test(Eiffel): - - def m(self, arg): - """Make it a little larger""" - return arg + 1 - - def m2(self, arg): - """Make it a little larger""" - return arg + 1 - - def m2_pre(self, arg): - assert arg > 0 - - def m2_post(self, result, arg): - assert result > arg - - class Sub(Test): - def m2(self, arg): - return arg**2 - def m2_post(self, Result, arg): - super(Sub, self).m2_post(Result, arg) - assert Result < 100 - - t = Test() - t.m(1) - t.m2(1) - try: - t.m2(0) - except AssertionError: - pass - else: - assert False - - s = Sub() - try: - s.m2(1) - except AssertionError: - pass # result == arg - else: - assert False - try: - s.m2(10) - except AssertionError: - pass # result == 100 - else: - assert False - s.m2(5) - -if __name__ == "__main__": - _test(EiffelMetaClass1) - _test(EiffelMetaClass2) diff --git a/AppPkg/Applications/Python/Python-2.7.2/Demo/newmetaclasses/Enum.py b/AppPkg/Applications/Python/Python-2.7.2/Demo/newmetaclasses/Enum.py deleted file mode 100644 index a080e8d..0000000 --- a/AppPkg/Applications/Python/Python-2.7.2/Demo/newmetaclasses/Enum.py +++ /dev/null @@ -1,177 +0,0 @@ -"""Enumeration metaclass.""" - -class EnumMetaclass(type): - """Metaclass for enumeration. - - To define your own enumeration, do something like - - class Color(Enum): - red = 1 - green = 2 - blue = 3 - - Now, Color.red, Color.green and Color.blue behave totally - different: they are enumerated values, not integers. - - Enumerations cannot be instantiated;
