Fred Drake a44d353e2b Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Jeremy Hylton c5007aa5c3 final patches from Neil Schemenauer for garbage collection 2000-06-30 05:02:53 +00:00
Fred Drake 13634cf7a4 This patch addresses two main issues: (1) There exist some non-fatal
errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"

(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))

As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.

These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.

Jeremy Hylton d08b4c4524 part 2 of Neil Schemenauer's GC patches:
This patch modifies the type structures of objects that
participate in GC.  The object's tp_basicsize is increased when
GC is enabled.  GC information is prefixed to the object to
maintain binary compatibility.  GC objects also define the
tp_flag Py_TPFLAGS_GC.

implementation.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum 0dabacee16 Make function objects somewhat mutable -- the members func_code,
func_defaults and func_doc (alias __doc__) may be assigned to.  For
the first two, there's a type restriction to code object and tuple,
respectively.

Guido van Rossum 1d5735e846 Merge back to main trunk 1994-08-30 08:27:36 +00:00
Guido van Rossum 590baa4a7a * import.c (get_module): pass .py filename to parse_file, not .pyc filename!
* funcobject.c (func_repr): don't call getstringvalue(None) for anonymous
  functions.
* bltinmodule.c: removed lambda (which is now a built-in function);
  removed implied lambda for string arg to filter/map/reduce.
* Grammar, graminit.[ch], compile.[ch]: replaced lambda as built-in
  function by lambda as grammar entity: instead of "lambda('x: x+1')" you
  write "lambda x: x+1".
* Xtmodule.c (checkargdict): return 0, not NULL, for error.

Guido van Rossum 2e8f8a398e Added compare operations for functions and code objects.
(Also hash, but it doesn't work yet.)
1993-11-05 10:20:10 +00:00
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 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
