Marc-André Lemburg 53f3d4ac74 [ Bug #116174 ] using %% in cstrings sometimes fails with unicode paramsFix for the bug reported in Bug #116174: "%% %s" % u"abc" failed due
to the way string formatting delegated work to the Unicode formatting
function.

Fred Drake d5fadf75e4 Rationalize use of limits.h, moving the inclusion to Python.h.
Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.

This closes SourceForge patch #101659 and bug #115323.

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.

Marc-André Lemburg d1ba443206 This patch adds a new Python C API called PyString_AsStringAndSize()
which implements the automatic conversion from Unicode to a string
object using the default encoding.

The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.

As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.

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).

Barry Warsaw 4df762ff98 Insure properly identifies the `interned' dictionary as leaking at
shutdown time, but CVS log entry for revision 2.45 explains why this
is so.  Simply include a comment so we don't have to re-figure it out
again 5 years from now.

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 ;)

Barry Warsaw 771d0675b6 string_join(): Some cleaning up of reference counting. In the
seqlen==1 clause, before returning item, we need to DECREF seq.  In
the res=PyString... failure clause, we need to goto finally to also
decref seq (and the DECREF of res in finally is changed to a
XDECREF).  Also, we need to DECREF seq just before the
PyUnicode_Join() return.

Jeremy Hylton 4904829dbf fix two refcount bugs in new string_join implementation:
1. PySequence_Fast_GET_ITEM is a macro and borrows a reference
2. The seq returned from PySequence_Fast must be decref'd
2000-07-11 03:28:17 +00:00
Jeremy Hylton 194e43e953 two changes to string_join:
implementation -- use PySequence_Fast interface to iterate over elements
interface -- if instance object reports wrong length, ignore it;
   previous version raised an IndexError if reported length was too high

Tim Peters c2e7da9859 Somebody started playing with const, so of course the outcome
was cascades of warnings about mismatching const decls.  Overall,
I think const creates lots of headaches and solves almost
nothing.  Added enough consts to shut up the warnings, but
this did require casting away const in one spot too (another
usual outcome of starting down this path):  the function
mymemreplace can't return const char*, but sometimes wants to
return its first argument as-is, which latter must be declared
const char* in order to avoid const warnings at mymemreplace's
call sites.  So, in the case the function wants to return the
first arg, that arg's declared constness must be subverted.

Fred Drake ba09633e1e ANSI-fication of the sources. 2000-07-09 07:04:36 +00:00
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.
2000-07-06 11:29:01 +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().

Guido van Rossum c682140de7 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]). slice_index()
is renamed _PyEval_SliceIndex() and is now exported. As well, the return
values for success/fail were changed to make slice_index directly
usable as required by the "O&" formatter.

[GvR: shouldn't a similar patch be applied to unicodeobject.c?]

Guido van Rossum b8f820c5a9 The methods islower(), isupper(), isspace(), isdigit() and istitle()
gave bogus results for chars in the range 128-255, because their
implementation was using signed characters.  Fixed this by using
unsigned character pointers (as opposed to using Py_CHARMASK()).

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 f0b7b04ae8 Marc-Andre Lemburg:
The maxsplit functionality in .splitlines() was replaced by the keepends
functionality which allows keeping the line end markers together
with the string.

Added support for '%r' % obj: this inserts repr(obj) rather
than str(obj).
2000-04-11 15:39:26 +00:00
Guido van Rossum 90daa87569 Marc-Andre Lemburg:
* string_contains now calls PyUnicode_Contains() only when the other
  operand is a Unicode string (not whenever it's not a string).

* New format style '%r' inserts repr(arg) instead of str(arg).

* '...%s...' % u"abc" now coerces to Unicode just like
  string methods. Care is taken not to reevaluate already formatted
  arguments -- only the first Unicode object appearing in the
  argument mapping is looked up twice. Added test cases for
  this to test_unicode.py.

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).

Guido van Rossum 98c9eba945 Fix bug discovered by John W. Shipman -- when the width of a format
specifier came from an int expression instead of a constant in the
format, a negative width was truncated to zero instead of taken to
mean the same as that negative constant plugged into the format.  E.g.
"(%*s)" % (-5, "foo") yielded "(foo)" while "(%-5s)" yields "(foo  )".
Now both yield the latter -- like sprintf() in C.

Guido van Rossum 971a7aaeac Change the Fini function to only remove otherwise unreferenced strings
from the interned table.  There are references in hard-to-find static
variables all over the interpreter, and it's not worth trying to get
rid of all those; but "uninterning" isn't fair either and may cause
subtle failures later -- so we have to keep them in the interned
table.

Also get rid of no-longer-needed insert of None in interned dict.
1997-08-05 02:15:12 +00:00
Guido van Rossum 8cf0476474 Added internal routine PyString_Fini() which deletes all interned
