Jeffrey Yasskin d7b00334f3 Add rational.Rational as an implementation of numbers.Rational with infinite 
precision. This has been discussed at http://bugs.python.org/issue1682. It's
useful primarily for teaching, but it also demonstrates how to implement a
member of the numeric tower, including fallbacks for mixed-mode arithmetic.

I expect to write a couple more patches in this area:
 * Rational.from_decimal()
 * Rational.trim/approximate() (maybe with different names)
 * Maybe remove the parentheses from Rational.__str__()
 * Maybe rename one of the Rational classes
 * Maybe make Rational('3/2') work.

Christian Heimes c3b2a4afe8 Added more comments to the new structseq repr code and implemented several of Neal's suggestions. 2008-01-14 06:06:19 +00:00
Christian Heimes c94e2b5c12 Now that I've learnt about structseq objects I felt like converting sys.float_info to a structseq. It's 
readonly and help(sys.float_info) explains the attributes nicely.

Christian Heimes 9c2019632b Added new an better structseq representation. E.g. repr(time.gmtime(0)) now returns 'time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)' instead of '(1970, 1, 1, 0, 0, 0, 3, 1, 0)'. The feature is part of #1816: sys.flags 2008-01-14 03:33:52 +00:00
Amaury Forgeot d'Arc 7cdf5f5c31 ?Why did my tests not notice this before? 
Slots inheritance is very different from OO inheritance.
This code lead to infinite recursion on classes derived from StructType.

Amaury Forgeot d'Arc e4c270c2a8 Re-apply patch #1700288 (first applied in r59931, rolled back in r59940) 
now that ctypes uses a more supported method to create types:

Method cache optimization, by Armin Rigo, ported to 2.6 by Kevin Jacobs.
 2008-01-14 00:29:41 +00:00
Amaury Forgeot d'Arc 08ccf202e6 As discussed in issue 1700288: 
ctypes takes some liberties when creating python types: it modifies the types'
__dict__ directly, bypassing all the machinery of type objects which deal with
special methods.  And this broke recent optimisations of method lookup.
Now we try to modify the type with more "official" functions.

Georg Brandl d1c131a6e3 Back out r59931 - test_ctypes fails with it. 2008-01-13 15:04:05 +00:00
Ka-Ping Yee 9e0f116fac Check in the patch proposed by Ben Hayden (benjhayden) for issue 
#1550: help('modules') broken by several 3rd party libraries.

Tested with Python build: trunk:54235:59936M -- the reported error
occurs with Django installed (or with any __init__.py present on
the path that raises an exception), and such errors indeed go away
when this change is applied.

The sqlite3 dll, when compiled in debug mode, must be linked with
  /MDd to use the debug runtime library.  Further, the dll will be
  named sqlite3_d.dll.
