Tim Peters 7d3a511a40 Cray J90 fixes for long ints.
This was a convenient excuse to create the pyport.h file recently
discussed!
Please use new Py_ARITHMETIC_RIGHT_SHIFT when right-shifting a
signed int and you *need* sign-extension.  This is #define'd in
pyport.h, keying off new config symbol SIGNED_RIGHT_SHIFT_ZERO_FILLS.
If you're running on a platform that needs that symbol #define'd,
the std tests never would have worked for you (in particular,
at least test_long would have failed).
The autoconfig stuff got added to Python after my Unix days, so
I don't know how that works.  Would someone please look into doing
& testing an auto-config of the SIGNED_RIGHT_SHIFT_ZERO_FILLS
symbol?  It needs to be defined if & only if, e.g., (-1) >> 3 is
not -1.

Greg Stein a90b23c571 One of the new prototypes was missing the "void" args. 2000-07-08 00:46:19 +00:00
Tim Peters 9ace6bc7ef Got RID of redundant coercions in longobject.c (as spotted by Greg
Stein -- thanks!).  Incidentally removed all the Py_PROTO macros
from object.h, as they prevented my editor from magically finding
the definitions of the "coercion", "cmpfunc" and "reprfunc"
typedefs that were being redundantly applied in longobject.c.

Marc-André Lemburg fa1309fd72 Fix to use Py_UCS4 2000-07-07 17:45:37 +00:00
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.
2000-07-07 13:46:42 +00:00
Marc-André Lemburg 295b1bbca1 Defunct the _XOPEN_SOURCE define for now. Suggested by Fredrik
Lundh as response to bug reports on True64 and IRIX.
2000-07-07 11:24:49 +00:00
Marc-André Lemburg 43279100f4 Bill Tutt: Added Py_UCS4 typedef to hold UCS4 values (these need
at least 32 bits as opposed to Py_UNICODE which rely on having
16 bits).
2000-07-07 09:01:41 +00:00
Marc-André Lemburg 3d1a1d7f0c Added prototypes for the new codec APIs for strings. These APIs
match the ones in the Unicode implementation, but were extended
to be able to reuse the existing Unicode codecs for string
purposes too.

Conversion from string to Unicode and back are done using the
default encoding.
2000-07-06 11:25:40 +00:00
Marc-André Lemburg f03e74126e Modified the ISALPHA and ISALNUM macros to use the new lookup APIs
from unicodectype.c
2000-07-05 09:45:59 +00:00
Marc-André Lemburg 82249c8389 Added #defines to enable SUSv2 compatibility where available and
to switch on support for BSD and SysV on platforms which use glibc
such as Linux.

These #defines are documented in e.g. the file /usr/include/features.h
on Linux platforms and the SUSv2 docs.
2000-07-05 08:53:18 +00:00
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).
2000-07-04 17:44:48 +00:00
Marc-André Lemburg a9c103bc09 Added new Py_UNICODE_ISALPHA() and Py_UNICODE_ISALNUM() macros
which are true for alphabetic and alphanumeric characters resp.

The macros are currently implemented using the existing is* tables
but will have to be updated to meet the Unicode standard definitions
(add tables for non-cased letters and letter modifiers).

Guido van Rossum 632ea6e353 Bump version to 2.0b1. 2000-06-29 22:29:24 +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.

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 e92e610a9e Christian Tismer -- total rewrite on trashcan code.
Improvements:
- does no longer need any extra memory
- has no relationship to tstate
- works in debug mode
- can easily be modified for free threading (hi Greg:)

Side effects:
Trashcan does change the order of object destruction.
Prevending that would be quite an immense effort, as
my attempts have shown. This version works always
the same, with debug mode or not. The slightly
changed destruction order should therefore be no problem.

Algorithm:
While the old idea of delaying the destruction of some
obejcts at a certain recursion level was kept, we now
no longer aloocate an object to hold these objects.
The delayed objects are instead chained together
via their ob_type field. The type is encoded via
ob_refcnt. When it comes to the destruction of the
chain of waiting objects, the topmost object is popped
off the chain and revived with type and refcount 1,
then it gets a normal Py_DECREF.

I am confident that this solution is near optimum
for minimizing side effects and code bloat.

Guido van Rossum 08df3ac066 Bump version to 1.6a2 -- to be released one of these days. 2000-04-06 15:01:30 +00:00
Guido van Rossum 9e896b37c7 Marc-Andre's third try at this bulk patch seems to work (except that
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent).  Checkin messages:


New Unicode support for int(), float(), complex() and long().

- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
  Unicode to a decimal char* string (used in the above new
  APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above

Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
  are masked, all other errors such as ValueError during
  Unicode coercion are passed through (note that PyUnicode_Compare
  does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
  masked and 0 returned; all other errors are passed through

Better testing support for the standard codecs.

Misc minor enhancements, such as an alias dbcs for the mbcs codec.

Changes:
- PyLong_FromString() now applies the same error checks as
  does PyInt_FromString(): trailing garbage is reported
  as error and not longer silently ignored. The only characters
  which may be trailing the digits are 'L' and 'l' -- these
  are still silently ignored.
- string.ato?() now directly interface to int(), long() and
  float(). The error strings are now a little different, but
  the type still remains the same. These functions are now
  ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
  in the input string; PyNumber_Long() already did this (and
  still does)

Followed by:

Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).

I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).

Guido van Rossum 24bdb0474f Marc-Andre Lemburg:
The attached patch set includes a workaround to get Python with
Unicode compile on BSDI 4.x (courtesy Thomas Wouters; the cause
is a bug in the BSDI wchar.h header file) and Python interfaces
for the MBCS codec donated by Mark Hammond.

Also included are some minor corrections w/r to the docs of
the new "es" and "es#" parser markers (use PyMem_Free() instead
of free(); thanks to Mark Hammond for finding these).

The unicodedata tests are now in a separate file
(test_unicodedata.py) to avoid problems if the module cannot
be found.

Barry Warsaw 51ac58039f On 17-Mar-2000, Marc-Andre Lemburg said:
Attached you find an update of the Unicode implementation.

    The patch is against the current CVS version. I would appreciate
    if someone with CVS checkin permissions could check the changes
    in.

    The patch contains all bugs and patches sent this week and also
    fixes a leak in the codecs code and a bug in the free list code
    for Unicode objects (which only shows up when compiling Python
    with Py_DEBUG; thanks to MarkH for spotting this one).

1999-10-12 19:54:53 +00:00
Guido van Rossum 8746082175 Patch by Tim Peters:
Introduce a new builtin exception, UnboundLocalError, raised when ceval.c
tries to retrieve or delete a local name that isn't bound to a value.
Currently raises NameError, which makes this behavior a FAQ since the same
error is raised for "missing" global names too:  when the user has a global
of the same name as the unbound local, NameError makes no sense to them.
Even in the absence of shadowing, knowing whether a bogus name is local or
global is a real aid to quick understanding.

Example:

D:\src\PCbuild>type local.py
x = 42

def f():
    print x
    x = 13
    return x

f()

D:\src\PCbuild>python local.py
Traceback (innermost last):
  File "local.py", line 8, in ?
    f()
  File "local.py", line 4, in f
    print x
UnboundLocalError: x

D:\src\PCbuild>

Note that UnboundLocalError is a subclass of NameError, for compatibility
with existing class-exception code that may be trying to catch this as a
NameError.  Unfortunately, I see no way to make this wholly compatible
with -X (see comments in bltinmodule.c):  under -X, [UnboundLocalError
is an alias for NameError --GvR].

[The ceval.c patch differs slightly from the second version that Tim
submitted; I decided not to raise UnboundLocalError for DELETE_NAME,
only for DELETE_LOCAL.  DELETE_NAME is only generated at the module
level, and since at that level a NameError is raised for referencing
an undefined name, it should also be raised for deleting one.]

Guido van Rossum f1176c4815 New version identification scheme.
The version numbers are now exported by Python.h.
Also rolled back the API version change -- it's back to 1007!

Guido van Rossum a8b47fe5c6 I can't seem to do anything right :-)
As Chris H. points out, I should have added 'extern' to the
declaration of _PyThreadState_Current.  Here it is.

Guido van Rossum 65d5b5763c Thanks to Chris Herborth, the thread primitives now have proper Py*
names in the source code (they already had those for the linker,
through some smart macros; but the source still had the old, un-Py names).
1998-12-21 19:32:43 +00:00
Guido van Rossum 275ea67e6b Add macro version of PyThreadState_GET(). This uses
_PyThreadState_Current, defined in pystate.c.

Guido van Rossum cc34faaf14 Add prototypes for PyOS_strto[u]l -- Chris Herborth. 1998-12-10 16:54:17 +00:00
Guido van Rossum f0f3600d0b Undo the change here -- there's no point in declaring a static
function as DL_IMPORT()!
1998-12-08 13:23:22 +00:00
Guido van Rossum 43466ec7b0 Add DL_IMPORT(returntype) for all officially exported functions. 1998-12-04 18:48:25 +00:00

Guido van Rossum d1f2d7eede Bump the patch level to 1.5.2b2, just in case I feel like releasing
next week. :-)

Guido van Rossum 36eef3c173 Changes by Greg Stein (code) and GvR (design).
Add a new member to the PyBufferProcs struct, bf_getcharbuffer.  For
backward compatibility, this member should only be used (this includes
testing for NULL!) when the flag Py_TPFLAGS_HAVE_GETCHARBUFFER is set
in the type structure, below.  Note that if its flag is not set, we
may be looking at an extension module compiled for 1.5.1, which will
have garbage at the bf_getcharbuffer member (because the struct wasn't
as long then).  If the flag is one, the pointer may still be NULL.
The function found at this member is used in a similar manner as
bf_getreadbuffer, but it is known to point to 8-bit character data.
(See discussion in getargs.c checked in later.)

As a general feature for extending the type structure and the various
structures that (may) hang off it in a backwards compatible way, we
rename the tp_xxx4 "spare" slot to tp_flags.  In 1.5.1 and before,
this slot was always zero.  In 1.5.1, it may contain various flags
indicating extra fields that weren't present in 1.5.1.  The only flag
defined so far is for the bf_getcharbuffer member of the PyBufferProcs
struct.

Note that the new spares (tp_xxx5 - tp_xxx8), once they become used,
should also be protected by a flag (or flags) in tp_flags.

Guido van Rossum d076c73cc8 Changes to support other object types besides strings
as the code string of code objects, as long as they support
the (readonly) buffer interface.  By Greg Stein.
