Guido van Rossum b3f7258f14 * Lots of small changes related to access.
* Added "access *: ...", made access work for class methods.
* Introduced subclass check: make sure that when calling
  ClassName.methodname(instance, ...), the instance is an instance of
  ClassName or of a subclass thereof (this might break some old code!)

Guido van Rossum 81daa32c15 Access checks now work, at least for instance data (not for methods
yet).  The class is now passed to eval_code and stored in the current
frame.  It is also stored in instance method objects.  An "unbound"
instance method is now returned when a function is retrieved through
"classname.funcname", which when called passes the class to eval_code.

Guido van Rossum 25831652fd Several changes in one:
(1) dictionaries/mappings now have attributes values() and items() as
well as keys(); at the C level, use the new function mappinggetnext()
to iterate over a dictionary.

(2) "class C(): ..." is now illegal; you must write "class C: ...".

(3) Class objects now know their own name (finally!); and minor
improvements to the way how classes, functions and methods are
represented as strings.

(4) Added an "access" statement and semantics.  (This is still
experimental -- as long as you don't use the keyword 'access' nothing
should be changed.)

Guido van Rossum 8a0c3456c2 Fix bug in class instance hash (forgot to clear error condition). 1993-04-08 12:56:19 +00:00
Guido van Rossum 9bfef44d97 * Changed all copyright messages to include 1993.
* Stubs for faster implementation of local variables (not yet finished)
* Added function name to code object.  Print it for code and function
  objects.  THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version
  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
* Replaced "dictobject" with more powerful "mappingobject"
* New per-type functio tp_hash to implement arbitrary object hashing,
  and hashobject() to interface to it
* Added built-in functions hash(v) and hasattr(v, 'name')
* classobject: made some functions static that accidentally weren't;
  added __hash__ special instance method to implement hash()
* Added proper comparison for built-in methods and functions

Guido van Rossum e537240c25 * Changed many files to use mkvalue() instead of newtupleobject().
* Fixcprt.py: added [-y file] option, do only files younger than file.
* modsupport.[ch]: added vmkvalue().
* intobject.c: use mkvalue().
* stringobject.c: added "formatstring"; renamed string* to string_*;
  ceval.c: call formatstring for string % value.
* longobject.c: close memory leak in divmod.
* parsetok.c: set result node to NULL when returning an error.

Guido van Rossum 9e51f9bec8 bltinmodule.c: added round(x, [n]); coerce() of two class instances
will try to coerce anyway.
classobject.c: instance 'nonzero' should first try __nonzero__
only then __len__.
1993-02-12 16:29:05 +00:00
Guido van Rossum d014ea6b5e * classobject.c: in instance_lenth, test result of call_object
for exception before using it.  Fixed a few other places where the
  outcome of calling sq_length wasn't tested for exceptions
  (bltinmodule.c, ceval.c).
1992-11-26 10:30:26 +00:00
Guido van Rossum 7066dd75c5 * Makefile: added IMGFILE; moved some stuff around.
* flmodule.c: added some missing functions; changed readonly flags of
  some data members based upon FORMS documentation.
* listobject.c: fixed int/long arg lint bug (bites PC compilers).
* several: removed redundant print methods (repr is good enough).
* posixmodule.c: added (still experimental) process group functions.

Guido van Rossum 1899c2e055 Made builtins int(), long(), float(), oct() and hex() more generic. 1992-09-12 11:09:23 +00:00
Guido van Rossum 94472a0374 classobject.c moduleobject.c stdwinmodule.c xxobject.c:
raise AttributeError, not KeyError, when attribute deletion fails.
sunaudiodevmodule.c: check for deletion before calling setmember.

Guido van Rossum ebc8c51cde Compare instance methods by comparing the object and the function. 1992-09-03 20:39:51 +00:00
Guido van Rossum 6d946f98bd * macmodule.c: include allobjects.h, not .c
* timemodule.c: the mac has no unistd.h
* classobject.c: fixed several cases of return NULL that should be
  return -1 !!!
1992-08-14 13:49:30 +00:00
Guido van Rossum e6eefc2231 * classobject.[ch], {float,long,int}object.c, bltinmodule.c:
coercion is now completely generic.
* ceval.c: for instances, don't coerce for + and *; * reverses
  arguments if left one is non-instance numeric and right one sequence.

Guido van Rossum 04691fc1c1 Changes so that user-defined classes can implement operations invoked
by special syntax: you can now define your own numbers, sequences and
mappings.
