Guido van Rossum 6c9e130524 - Removed FutureWarnings related to hex/oct literals and conversions
and left shifts.  (Thanks to Kalle Svensson for SF patch 849227.)
  This addresses most of the remaining semantic changes promised by
  PEP 237, except for repr() of a long, which still shows the trailing
  'L'.  The PEP appears to promise warnings for operations that
  changed semantics compared to Python 2.3, but this is not
  implemented; we've suffered through enough warnings related to
  hex/oct literals and I think it's best to be silent now.

Raymond Hettinger 4f8f976576 Add optional fillchar argument to ljust(), rjust(), and center() string methods. 2003-11-26 08:21:35 +00:00
Walter Dörwald 4894c30626 Fix a bug in the memory reallocation code of PyUnicode_TranslateCharmap().
charmaptranslate_makespace() allocated more memory than required for the
next replacement but didn't remember that fact, so memory size was growing
exponentially every time a replacement string is longer that one character.
This fixes SF bug #828737.

Jeremy Hylton 504de6bd2c Fix for SF bug [ 817156 ] invalid \U escape gives 0=length unistr. 2003-10-06 05:08:26 +00:00
Tim Peters ced69f8a20 On c.l.py, Martin v. Löwis said that Py_UNICODE could be of a signed type,
so fiddle Jeremy's fix to live with that.  Also added more comments.

Bugfix candidate (this bug is in all versions of Python, at least since
2.1).

Jeremy Hylton d808279be3 Double-fix of crash in Unicode freelist handling.
If a length-1 Unicode string was in the freelist and it was
uninitialized or pointed to a very large (magnitude) negative number,
the check

	 unicode_latin1[unicode->str[0]] == unicode

could cause a segmentation violation, e.g. unicode->str[0] is 0xcbcbcbcb.

Fix this in two ways:

1. Change guard befor unicode_latin1[] to test against 256U.  If I
   understand correctly, the unsigned long used to store UCS4 on my
   box was getting converted to a signed long to compare with the
   signed constant 256.

2. Change _PyUnicode_New() to make sure the first element of str is
   always initialized to zero.  There are several places in the code
   where the caller can exit with an error before initializing any
   of str, which would leave junk in str[0].

Also, silence a compiler warning on pointer vs. int arithmetic.

Bug fix candidate.

Jeremy Hylton deb2dc6658 Change checks of PyUnicode_Resize() return value for clarity.
The unicode_resize() family only returns -1 or 0 so simply checking
for != 0 is sufficient, but somewhat unclear.  Many Python API
functions return < 0 on error, reserving the right to return 0 or 1 on
success.  Change the call sites for consistency with these calls.

Walter Dörwald d4ade0885c Fix another refcounting leak (in PyUnicode_DecodeUnicodeEscape()). 2003-08-15 15:00:26 +00:00
Walter Dörwald e5402fb340 Fix refcount leak in PyUnicode_EncodeCharmap(). The bug surfaces
when an encoding error occurs and the callback name is unknown,
i.e. when the callback has to be called. The problem was that
the fact that the callback has already been looked up was only
recorded in a local variable in charmap_encoding_error(), because
charmap_encoding_error() got it's own copy of the errorHandler
pointer instead of a pointer to the pointer in
PyUnicode_EncodeCharmap().

Walter Dörwald 2e0b18af30 Change the treatment of positions returned by PEP293
error handers in the Unicode codecs: Negative
positions are treated as being relative to the end of
the input and out of bounds positions result in an
IndexError.

Also update the PEP and include an explanation of
this in the documentation for codecs.register_error.

Fixes a small bug in iconv_codecs: if the position
from the callback is negative *add* it to the size
instead of substracting it.

From SF patch #677429.

Neal Norwitz 80a1bf4b5d Fix SF # 635969, No error "not all arguments converted"
When mwh added extended slicing, strings and unicode became mappings.
Thus, dict was set which prevented an error when doing:
	newstr = 'format without a percent' % string_value

This fix raises an exception again when there are no formats
and % with a string value.

Guido van Rossum 049cd6b563 Fix a nasty endcase reported by Armin Rigo in SF bug 618623:
'%2147483647d' % -123 segfaults.  This was because an integer overflow
in a comparison caused the string resize to be skipped.  After fixing
the overflow, this could call _PyString_Resize() with a negative size,
so I (1) test for that and raise MemoryError instead; (2) also added a
test for negative newsize to _PyString_Resize(), raising SystemError
as for all bad arguments.

An identical bug existed in unicodeobject.c, of course.

Will backport to 2.2.2.

Guido van Rossum 2023c9b84a Fix SF bug 599128, submitted by Inyeol Lee: .replace() would do the
wrong thing for a unicode subclass when there were zero string
replacements.  The example given in the SF bug report was only one way
to trigger this; replacing a string of length >= 2 that's not found is
another.  The code would actually write outside allocated memory if
replacement string was longer than the search string.

(I wonder how many more of these are lurking?  The unicode code base
is full of wonders.)

Guido van Rossum 078151da90 Implement stage B0 of PEP 237: add warnings for operations that
currently return inconsistent results for ints and longs; in
particular: hex/oct/%u/%o/%x/%X of negative short ints, and x<<n that
either loses bits or changes sign.  (No warnings for repr() of a long,
though that will also change to lose the trailing 'L' eventually.)

This introduces some warnings in the test suite; I'll take care of
those later.

Jeremy Hylton 938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.

Guido van Rossum cacfc07d08 - A new type object, 'string', is added. This is a common base type
for 'str' and 'unicode', and can be used instead of
  types.StringTypes, e.g. to test whether something is "a string":
  isinstance(x, string) is True for Unicode and 8-bit strings.  This
  is an abstract base class and cannot be instantiated directly.

Raymond Hettinger 0ebac97058 Patch 549187. Improve string formatting error message. 2002-05-21 15:14:57 +00:00
Tim Peters 5de9842b34 Repair widespread misuse of _PyString_Resize. Since it's clear people
don't understand how this function works, also beefed up the docs.  The
most common usage error is of this form (often spread out across gotos):

	if (_PyString_Resize(&s, n) < 0) {
		Py_DECREF(s);
		s = NULL;
		goto outtahere;
	}

The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL.  So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s):  s is already
NULL!  A correct way to write the above is the simpler (and intended)

	if (_PyString_Resize(&s, n) < 0)
		goto outtahere;

Bugfix candidate.

Tim Peters 602f740bc2 SF patch 549375: Compromise PyUnicode_EncodeUTF8
This implements ideas from Marc-Andre, Martin, Guido and me on Python-Dev.

"Short" Unicode strings are encoded into a "big enough" stack buffer,
then exactly as much string space as they turn out to need is allocated
at the end.  This should have speed benefits akin to Martin's "measure
once, allocate once" strategy, but without needing a distinct measuring
pass.

"Long" Unicode strings allocate as much heap space as they could possibly
need (4 x # Unicode chars), and do a realloc at the end to return the
untouched excess.  Since the overallocation is likely to be substantial,
this shouldn't burden the platform realloc with unusably small excess
blocks.

Also simplified uses of the PyString_xyz functions.  Also added a release-
build check that 4*size doesn't overflow a C int.  Sooner or later, that's
going to happen.

Guido van Rossum 77f6a65eb0 Add the 'bool' type and its values 'False' and 'True', as described in
PEP 285.  Everything described in the PEP is here, and there is even
some documentation.  I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison.  I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.

Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.

Marc-André Lemburg bd3be8f0ca Fix to the UTF-8 encoder: it failed on 0-length input strings.
Fix for the UTF-8 decoder: it will now accept isolated surrogates
(previously it raised an exception which causes round-trips to
fail).

Added new tests for UTF-8 round-trip safety (we rely on UTF-8 for
marshalling Unicode objects, so we better make sure it works for
all Unicode code points, including isolated surrogates).

Bumped the PYC magic in a non-standard way -- please review. This
was needed because the old PYC format used illegal UTF-8 sequences
for isolated high surrogates which now raise an exception.

Marc-André Lemburg 72f8213ba4 Fix for bug #438164: %-formatting using Unicode objects.
This patch also does away with an incompatibility between Jython
and CPython.

Guido van Rossum b8c65bc27f SF patch #470578: Fixes to synchronize unicode() and str()
This patch implements what we have discussed on python-dev late in
    September: str(obj) and unicode(obj) should behave similar, while
    the old behaviour is retained for unicode(obj, encoding, errors).

    The patch also adds a new feature with which objects can provide
    unicode(obj) with input data: the __unicode__ method. Currently no
    new tp_unicode slot is implemented; this is left as option for the
    future.

    Note that PyUnicode_FromEncodedObject() no longer accepts Unicode
    objects as input. The API name already suggests that Unicode
    objects do not belong in the list of acceptable objects and the
    functionality was only needed because
    PyUnicode_FromEncodedObject() was being used directly by
    unicode(). The latter was changed in the discussed way:

    * unicode(obj) calls PyObject_Unicode()
    * unicode(obj, encoding, errors) calls PyUnicode_FromEncodedObject()

    One thing left open to discussion is whether to leave the
    PyUnicode_FromObject() API as a thin API extension on top of
    PyUnicode_FromEncodedObject() or to turn it into a (macro) alias
    for PyObject_Unicode() and deprecate it. Doing so would have some
    surprising consequences though, e.g.  u"abc" + 123 would turn out
    as u"abc123"...

[Marc-Andre didn't have time to check this in before the deadline.  I
hope this is OK, Marc-Andre!  You can still make changes and commit
them on the trunk after the branch has been made, but then please mail
Barry a context diff if you want the change to be merged into the
2.2b1 release branch.  GvR]

Guido van Rossum 9475a2310d Enable GC for new-style instances. This touches lots of files, since
many types were subclassable but had a xxx_dealloc function that
called PyObject_DEL(self) directly instead of deferring to
self->ob_type->tp_free(self).  It is permissible to set tp_free in the
type object directly to _PyObject_Del, for non-GC types, or to
_PyObject_GC_Del, for GC types.  Still, PyObject_DEL was a tad faster,
so I'm fearing that our pystone rating is going down again.  I'm not
sure if doing something like

void xxx_dealloc(PyObject *self)
{
	if (PyXxxCheckExact(self))
		PyObject_DEL(self);
	else
		self->ob_type->tp_free(self);
}

is any faster than always calling the else branch, so I haven't
attempted that -- however those types whose own dealloc is fancier
(int, float, unicode) do use this pattern.

Marc-André Lemburg 3508e30861 Fix Unicode .join() method to raise a TypeError for sequence
elements which are not Unicode objects or strings. (This matches
the string.join() behaviour.)

Fix a memory leak in the .join() method which occurs in case
the Unicode resize fails.

Restore the test_unicode output.

Marc-André Lemburg 6871f6ac57 Implement the changes proposed in patch #413333. unicode(obj) now
works just like str(obj) in that it tries __str__/tp_str on the object
in case it finds that the object is not a string or buffer.

Marc-André Lemburg c60e6f7771 Patch #435971: UTF-7 codec by Brian Quinlan. 2001-09-20 10:35:46 +00:00
Tim Peters af90b3e610 str_subtype_new, unicode_subtype_new:
+ These were leaving the hash fields at 0, which all string and unicode
  routines believe is a legitimate hash code.  As a result, hash() applied
  to str and unicode subclass instances always returned 0, which in turn
  confused dict operations, etc.
+ Changed local names "new"; no point to antagonizing C++ compilers.

Tim Peters 7a29bd5861 More on bug 460020: disable many optimizations of unicode subclasses. 2001-09-12 03:03:31 +00:00
Tim Peters 78e0fc74bc Possibly the end of SF [#460020] bug or feature: unicode() and subclasses.
Changed unicode(i) to return a true Unicode object when i is an instance of
a unicode subclass.  Added PyUnicode_CheckExact macro.

Tim Peters 772747b3f1 SF patch #438013 Remove 2-byte Py_UCS2 assumptions
Removed all instances of Py_UCS2 from the codebase, and so also (I hope)
the last remaining reliance on the platform having an integral type
with exactly 16 bits.
PyUnicode_DecodeUTF16() and PyUnicode_EncodeUTF16() now read and write
one byte at a time.
