Guido van Rossum 3a03d4c4c7 Add two scenarios by Vladimir Marangozov that show how to use your own
allocator.

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 e326b1efe2 At last, this backward compatibility file bites the dust.
If you still haven't updated your extension since the Grand Renaming,
you don't deserve Python 1.6. :-)

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 004d64f362 Marc-Andre Lemburg:
Changed PyUnicode_Splitlines() maxsplit argument to keepends.
The maxsplit functionality was replaced by the keepends
functionality which allows keeping the line end markers together
with the string.

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).

    add * & ** options to arglist

Include/opcode.h & Lib/dis.py:
    define three new opcodes
        CALL_FUNCTION_VAR
        CALL_FUNCTION_KW
        CALL_FUNCTION_VAR_KW

Python/ceval.c:
    extend TypeError "keyword parameter redefined" message to include
        the name of the offending keyword
    reindent CALL_FUNCTION using four spaces
    add handling of sequences and dictionaries using extend calls
    fix function import_from to use PyErr_Format

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.

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).

Guido van Rossum d0d366b5e6 Marc-Andre Lemburg: add declaration for PyUnicode_Contains(). 2000-03-13 23:22:24 +00:00
Guido van Rossum d724b23420 Christian Tismer's "trashcan" patch:
Added wrapping macros to dictobject.c, listobject.c, tupleobject.c,
frameobject.c, traceback.c that safely prevends core dumps
on stack overflow. Macros and functions in object.c, object.h.
The method is an "elevator destructor" that turns cascading
deletes into tail recursive behavior when some limit is hit.

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.]

macro definition and instead fix the doco.
