Eric Smith aca19e6a74 Backport of some of the work in r71665 to trunk. This reworks much of
int, long, and float __format__(), and it keeps their implementation
in sync with py3k.

Also added PyOS_double_to_string. This is the "fallback" version
that's also available in trunk, and should be kept in sync with that
code. I'll add an issue to document PyOS_double_to_string in the C
API.

There are many internal cleanups. Externally visible changes include:

- Implement PEP 378, Format Specifier for Thousands Separator, for
  floats, ints, and longs.

- Issue #5515: 'n' formatting for ints, longs, and floats handles
  leading zero formatting poorly.

- Issue #5772: For float.__format__, don't add a trailing ".0" if
  we're using no type code and we have an exponent.

Kristján Valur Jónsson 170eee9d6a Fix those parts in the testsuite that assumed that sys.maxint would cause overflow on x64. Now the testsuite is well behaved on that platform. 2007-05-03 20:09:56 +00:00

Guido van Rossum 457bf91a7f Fix a bug discovered by Kalle Svensson: comparing sys.maxint to
2**32-1 makes no sense.  Use 2**31-1 instead.

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.

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.

Michael W. Hudson 549ab8a98d A test for the recent overflow-in-format-crash bug.
Only runs when sys.maxint == 2**32 - 1; different things go wrong
on a 64-bit box.

Neal Norwitz 88fe4ff5a9 Fix the problem of not raising a TypeError exception when doing:
'%g' % '1'
    '%d' % '1'

Add a test for these conditions
Fix the test so that if not exception is raise, this is a failure

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Martin v. Löwis 10d7255249 Use raw-unicode-escape for the tests that require it. 2001-08-17 22:08:34 +00:00
Martin v. Löwis 339d0f720e Patch #445762: Support --disable-unicode
- Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled
- check for Py_USING_UNICODE in all places that use Unicode functions
- disables unicode literals, and the builtin functions
- add the types.StringTypes list
- remove Unicode literals from most tests.

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.

Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Tim Peters a3a3a030af Fox for SF bug #123859: %[duxXo] long formats inconsistent. 2000-11-30 05:22:44 +00:00
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.
