Guido van Rossum b4db1944c4 When comparing objects, always check that tp_compare is not NULL
before calling it.  This check was there when the objects were of the
same type *before* coercion, but not if they initially differed but
became the same *after* coercion.

Guido van Rossum cd5a5f627a When comparing objects of different types (which is done by comparing
the type names), make sure that numeric objects are considered smaller
than all other objects, by forcing their name to "".

Guido van Rossum 1c4f458099 In PyObject_IsTrue(), don't call function pointers that are NULL
(nb_nonzero, mp_length, sq_length).

Guido van Rossum 9b00dfae75 If USE_STACKCHECK is defined use PyOS_CheckStack() in the repr and str
routines. This catches a slightly different set of crashes than the
recursive-repr fix.

Guido van Rossum db9351643d Instead of "attribute-less object", issue an error message that
contains the type of the object and name of the attribute.

Guido van Rossum 242c64256c Add a new function PyNumber_CoerceEx() which works just like
PyNumber_Coerce() except that when the coercion can't be done and no
other exceptions happen, it returns 1 instead of raising an
exception.

Use this function in PyObject_Compare() to avoid raising an exception
simply because two objects with numeric behavior can't be coerced to a
common type; instead, proceed with the non-numeric default comparison.

Note that this is a somewhat questionable practice -- comparisons for
numeric objects shouldn't default to random behavior like this, but it
is required for backward compatibility.  (Case in point, it broke
comparison of kjDict objects to integers in Aaron Watters' kjbuckets
extension.)  A correct fix (for python 2.0) should involve a different
definiton of comparison altogether.

Guido van Rossum 97ead3fb8e Hack to force loading of cobject.o 1996-01-12 01:24:09 +00:00
Sjoerd Mullender 6ec3c653da Implemented two new functions in sys:
getcounts() returns a list of counts of allocations and
		deallocations for all different object types.
	getobjects(n [, type ]) returns a list of recently allocated
		and not-yet-freed objects of the given type (all
		objects if no type given).  Only the n most recent
		(all if n==0) objects are returned.
getcounts is only available if compiled with -DCOUNT_ALLOCS,
getobjects is only available if compiled with -DTRACE_REFS.  Note that
everything must be compiled with these options!

Guido van Rossum 6610ad9d6b Added 1995 to copyright message.
floatobject.c: fix hash().
methodobject.c: support METH_FREENAME flag bit.
1995-01-04 19:07:38 +00:00
Guido van Rossum d7047b395e Lots of minor changes. Note for mappingobject.c: the hash table pointer
can now be NULL.
1995-01-02 19:07:15 +00:00
Guido van Rossum 9776adf565 rearranged code in debugging version of DELREF to avoid touching data
after it has been freed.

Guido van Rossum 1d5735e846 Merge back to main trunk 1994-08-30 08:27:36 +00:00
Guido van Rossum c600411755 * mpzmodule.c: removed redundant mpz_print function.
* object.[ch], bltinmodule.c, fileobject.c: changed str() to call
  strobject() which calls an object's __str__ method if it has one.
  strobject() is also called by writeobject() when PRINT_RAW is passed.
* ceval.c: rationalize code for PRINT_ITEM (no change in function!)
* funcobject.c, codeobject.c: added compare and hash functionality.
  Functions with identical code objects and the same global dictionary are
  equal.  Code objects are equal when their code, constants list and names
  list are identical (i.e. the filename and code name don't count).
  (hash doesn't work yet since the constants are in a list and lists can't
  be hashed -- suppose this should really be done with a tuple now we have
  resizetuple!)
1993-11-05 10:22:19 +00:00
Sjoerd Mullender 52c1f51554 import.c: When something is wrong with the .pyc, properly open the .py
file.
object.c: Write allocation statistics to stderr.
1993-10-25 08:40:52 +00:00
Sjoerd Mullender 3bb8a05947 Several optimizations and speed improvements.
cstubs: Use Matrix type instead of float[4][4].
1993-10-22 12:04:32 +00:00
Sjoerd Mullender 842d2ccdcd intobject.c: Save references to small integers, so that they can be
shared.  The default is to save references to the integers in
	the range -1..99.  The lower limit can be set by defining
	NSMALLNEGINTS (absolute value of smallest integer to be saved)
	and NSMALLPOSINTS (1 more than the largest integer to be
	saved).
tupleobject.c: Save a reference to the empty tuple to be returned
	whenever a tuple of size 0 is requested.  Tuples of size 1
	upto, but not including, MAXSAVESIZE (default 20) are put in
	free lists when deallocated.  When MAXSAVESIZE equals 1, only
	share references to the empty tuple, when MAXSAVESIZE equals
	0, don't include the code at all and revert to the old
	behavior.
object.c: Print some more statistics when COUNT_ALLOCS is defined.
1993-10-15 16:18:48 +00:00
Sjoerd Mullender a9c3c22c33 * Extended X interface: pixmap objects, colormap objects visual objects,
image objects, and lots of new methods.
* Added counting of allocations and deallocations of builtin types if
  COUNT_ALLOCS is defined.  Had to move calls to NEWREF down in some
  files.
* Bug fix in sorting lists.
1993-10-11 12:54:31 +00:00
Guido van Rossum ed18fdc9fc * accessobject.c (ownercheck): allow a base class access to protected
objects of its derived classes; allow anything that has an attribute
  named "__privileged__" access to anything.
* object.[ch]: added hasattr() -- test whether getattr() will succeed.
1993-07-11 19:55:34 +00:00
Guido van Rossum 6ac258d381 * pythonrun.c: Print exception type+arg *after* stack trace instead of
before it.
* ceval.c, object.c: moved testbool() to object.c (now extern visible)
* stringobject.c: fix bugs in and rationalize string resize in formatstring()
* tokenizer.[ch]: fix non-working code for lines longer than BUFSIZ
1993-05-12 08:24:20 +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
1993-03-29 10:43:31 +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.
1992-09-17 17:54:56 +00:00
Guido van Rossum 2e8f6140ff If a type has a repr function but no print function, printing it now
calls the repr function.  When the refcount is bad, don't print
the object at all (chances of crashes).
Changes to checking and printing of references: the consistency
check is somewhat faster; don't print strings referenced once
(most occur in function's name lists).
