Martin v. Löwis da3dc5b892 Patch #416953: Cache ASCII characters to speed up ASCII decoding. 2001-04-18 12:49:15 +00:00
Tim Peters fff5325078 Bug 415514 reported that e.g.
"%#x" % 0
blew up, at heart because C sprintf supplies a base marker if and only if
the value is not 0.  I then fixed that, by tolerating C's inconsistency
when it does %#x, and taking away that *Python* produced 0x0 when
formatting 0L (the "long" flavor of 0) under %#x itself.  But after talking
with Guido, we agreed it would be better to supply 0x for the short int
case too, despite that it's inconsistent with C, because C is inconsistent
with itself and with Python's hex(0) (plus, while "%#x" % 0 didn't work
before, "%#x" % 0L *did*, and returned "0x0").  Similarly for %#X conversion.

Tim Peters 711088d9b8 Fix for SF bug #415514: "%#x" % 0 caused assertion failure/abort.
http://sourceforge.net/tracker/index.php?func=detail&aid=415514&group_id=5470&atid=105470
For short ints, Python defers to the platform C library to figure out what
%#x should do.  The code asserted that the platform C returned a string
beginning with "0x".  However, that's not true when-- and only when --the
*value* being formatted is 0.  Changed the code to live with C's inconsistency
here.  In the meantime, the problem does not arise if you format a long 0 (0L)
instead.  However, that's because the code *we* wrote to do %#x conversions on
longs produces a leading "0x" regardless of value.  That's probably wrong too:
we should drop leading "0x", for consistency with C, when (& only when) formatting
0L.  So I changed the long formatting code to do that too.

Fredrik Lundh 06d126803c Move uchhash functionality into unicodedata (after the recent
crop of changes, the files are small enough to do this).  Also
adds "name" and "lookup" functions to unicodedata.
2001-01-24 07:59:11 +00:00
Fredrik Lundh f60560626c Better error message if ucnhash cannot be found (obscure attribute
errors aren't that helpful), or doesn't contain what's expected from
it.  Also tweaked the test script so it compiles even if ucnhash is
missing.
2001-01-20 11:15:25 +00:00
Fredrik Lundh 0fdb90cafe refactored the unicodeobject/ucnhash interface, to hide the

Marc-André Lemburg ad7c98e264 This patch adds a new builtin unistr() which behaves like str()
except that it always returns Unicode objects.

A new C API PyObject_Unicode() is also provided.

This closes patch #101664.

Marc-André Lemburg 3a645e4dd4 Added checks to prevent PyUnicode_Count() from dumping core
in case the parameters are out of bounds and fixes error handling
for .count(), .startswith() and .endswith() for the case of
mixed string/Unicode objects.

This patch adds Python style index semantics to PyUnicode_Count()
indices (including the special handling of negative indices).

The patch is an extended version of patch #103249 submitted
by Michael Hudson (mwh) on SF. It also includes new test cases.
2001-01-16 11:54:12 +00:00
Marc-André Lemburg ec233e5803 This patch adds a new feature to the builtin charmap codec:
The mapping dictionaries can now contain 1-n mappings, meaning
that character ordinals may be mapped to strings or Unicode object,
e.g. 0x0078 ('x') -> u"abc", causing the ordinal to be replaced by
the complete string or Unicode object instead of just one character.

Another feature introduced by the patch is that of mapping oridnals to
the emtpy string. This allows removing characters.

The patch is different from patch #103100 in that it does not cause a
performance hit for the normal use case of 1-1 mappings.

2001-01-06 14:59:58 +00:00
Marc-André Lemburg a866df806d This patch changes the default behaviour of the builtin charmap
codec to not apply Latin-1 mappings for keys which are not found
in the mapping dictionaries, but instead treat them as undefined
mappings.

The patch was originally written by Martin v. Loewis with some
additional (cosmetic) changes and an updated test script
by Marc-Andre Lemburg.

The standard codecs were recreated from the most current files
available at the Unicode.org site using the Tools/scripts/gencodec.py
tool.

This patch closes the bugs #116285 and #119960.

Tim Peters 38fd5b6413 Derived from Martin's SF patch 110609: support unbounded ints in %d,i,u,x,X,o formats.
Note a curious extension to the std C rules:  x, X and o formatting can never produce
a sign character in C, so the '+' and ' ' flags are meaningless for them.  But
unbounded ints *can* produce a sign character under these conversions (no fixed-
width bitstring is wide enough to hold all negative values in 2's-comp form).  So
these flags become meaningful in Python when formatting a Python long which is too
big to fit in a C long.  This required shuffling around existing code, which hacked
x and X conversions to death when both the '#' and '0' flags were specified:  the
hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or
'+' flags too, since signs were always meaningless before for x and X conversions.
Isomorphic shuffling was required in unicodeobject.c.
Also added dozens of non-trivial new unbounded-int test cases to test_format.py.
2000-09-21 05:43:11 +00:00
Tim Peters 8f422461b4 Fix for bug 113934. string*n and unicode*n did no overflow checking at
all, either to see whether the # of chars fit in an int, or that the
amount of memory needed fit in a size_t.  Checking these is expensive, but
the alternative is silently wrong answers (as in the bug report) or
core dumps (which were easy to provoke using Unicode strings).
2000-09-09 06:13:41 +00:00
Fredrik Lundh df84675f93 changed \x to consume exactly two hex digits, also for unicode

Marc-André Lemburg e5034378cc Removing UTF-16 aware Unicode comparison code. This kind of compare
function (together with other locale aware ones) should into a new collation
support module. See python-dev for a discussion of this removal.

Note: This patch should also be applied to the 1.6 branch.
2000-08-08 08:04:29 +00:00
Marc-André Lemburg bff879cabb This patch finalizes the move from UTF-8 to a default encoding in
the Python Unicode implementation.

The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).

Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.

(Note: this patch will also have to be applied to the 1.6 branch
 of the CVS tree.)

Marc-André Lemburg fb625847bf Fix to a bug found by Florian Weimer:
The UTF-8 decoder is still buggy (i.e. it doesn't pass Markus Kuhn's
stress test), mainly due to the following construct:

    #define UTF8_ERROR(details)  do {                       \
        if (utf8_decoding_error(&s, &p, errors, details))   \
            goto onError;                                   \
        continue;                                           \
    } while (0)

(The "continue" statement is supposed to exit from the outer loop,
but of course, it doesn't.  Indeed, this is a marvelous example of
the dangers of the C programming language and especially of the C
preprocessor.)

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Fredrik Lundh dde6164402 - changed hash calculation for unicode strings. the new

the C APIs should be made Unicode aware.

Guido van Rossum b8872e61c6 Trent Mick:
Fix the string methods that implement slice-like semantics with
optional args (count, find, endswith, etc.) to properly handle
indeces outside [INT_MIN, INT_MAX]. Previously the "i" formatter
for PyArg_ParseTuple was used to get the indices. These could overflow.

This patch changes the string methods to use the "O&" formatter with
the slice_index() function from ceval.c which is used to do the same
job for Python code slices (e.g. 'abcabcabc'[0:1000000000L]).

  though (switching it off is easy: see the unicodeobject.c
  file for details).

* Fixed a memory leak in the Unicode freelist cleanup code.

* Added tests to correctly process the return code from
  _PyUnicode_Resize().

* Fixed a bug in the 'ignore' error handling routines
  of some builtin codecs. Added test cases for these to
  test_unicode.py.

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).

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).
