Tim Peters 9f688bf9d2 Some cleanup of longs in prepartion for Cray J90 fixes: got
rid of Py_PROTO, switched to ANSI function decls, and did some
minor fiddling.
2000-07-07 15:53:28 +00:00
Marc-André Lemburg 5a5c81a0e9 Added new API PyUnicode_FromEncodedObject() which supports decoding
objects including instance objects.

The old API PyUnicode_FromObject() is still available as shortcut.

Marc-André Lemburg 063e0cb4c6 Fix to bug #393 (UTF16 codec didn't like empty strings) and
corrected some usage of 'unsigned long' where Py_UNICODE
should have been used.

Marc-André Lemburg 85cc4d8940 Fixed a couple of places where 'int' was used where 'long'
should have been used.

into 1000-case smaller ones.

Marc-André Lemburg 63f3d17418 Added new codec APIs and a new interface method .encode() which
works just like the Unicode one. The C APIs match the ones in the Unicode
implementation, but were extended to be able to reuse the existing
Unicode codecs for string purposes too.

Conversions from string to Unicode and back are done using the
default encoding.

Marc-André Lemburg 1f46860a29 Fix to bug #389:
Full_Name: Bastian Kleineidam
Version: 2.0b1 CVS 5.7.2000
OS: Debian Linux 2.2
Submission from: earth.cs.uni-sb.de (134.96.252.92)
2000-07-05 15:32:40 +00:00
Marc-André Lemburg a7acf425f6 Added new .isalpha() and .isalnum() methods which provide interfaces
to the new alphabetic lookup APIs in unicodectype.c.
2000-07-05 09:49:44 +00:00
Marc-André Lemburg f3938f55c7 Added new lookup API which matches all alphabetic Unicode characters,
i.e the ones with category 'Ll','Lu','Lt','Lo','Lm'.
2000-07-05 09:48:59 +00:00
Marc-André Lemburg 4027f8f4b3 Added new .isalpha() and .isalnum() methods to match the same
ones on the Unicode objects. Note that the string versions use
the (locale aware) C lib APIs isalpha() and isalnum().

Tim Peters 1f5871e834 Removed Py_PROTO and switched to ANSI C declarations in the dict
implementation.  This was really to test whether my new CVS+SSH
setup is more usable than the old one -- and turns out it is (for
whatever reason, it was impossible to do a commit before that
involved more than one directory).

Marc-André Lemburg 1e7205a62a Bill Tutt:

Marc-André Lemburg 891bc65486 If auto-conversion fails, the Unicode codecs will return NULL.
This is now checked and the error passed on to the caller.
2000-07-03 09:57:53 +00:00
Fredrik Lundh efecc7d05b changed repr and str to always convert unicode strings
to 8-bit strings, using the default encoding.

Guido van Rossum 9a15c211cf Fix an error on AIX by using a proper cast. 2000-06-30 22:46:04 +00:00
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.

Fred Drake 56780257c6 Thomas Wouters <thomas@xs4all.net>:
The following patch adds "sq_contains" support to rangeobject, and enables
the already-written support for sq_contains in listobject and tupleobject.

The rangeobject "contains" code should be a bit more efficient than the
current default "in" implementation ;-) It might not get used much, but it's
not that much to add.

listobject.c and tupleobject.c already had code for sq_contains, and the
proper struct member was set, but the PyType structure was not extended to
include tp_flags, so the object-specific code was not getting called (Go
ahead, test it ;-). I also did this for the immutable_list_type in
listobject.c, eventhough it is probably never used. Symmetry and all that.

Marc-André Lemburg 90e8147118 Marc-Andre Lemburg <mal@lemburg.com>:
Change the default encoding to 'ascii' (it was previously
defined as UTF-8).

Note: The implementation still uses UTF-8 to implement
the buffer protocol, so C APIs will still see UTF-8. This
is on purpose: rather than fixing the Unicode implementation,
the C APIs should be made Unicode aware.

This patch correct bounds checking in PyLong_FromLongLong. Currently, it does
not check properly for negative values when checking to see if the incoming
value fits in a long or unsigned long. This results in possible silent
truncation of the value for very large negative values.
