Thomas Wouters 553489ab1d As discussed on python-dev, silence three gcc-4.0.x warnings, using assert()
to protect against actual uninitialized usage.

Objects/longobject.c: In function ‘PyLong_AsDouble’:
Objects/longobject.c:655: warning: ‘e’ may be used uninitialized in this function

Objects/longobject.c: In function ‘long_true_divide’:
Objects/longobject.c:2263: warning: ‘aexp’ may be used uninitialized in this function

Neal Norwitz bab05c9604 Fix SF #1412837, compile failed with Watcom compiler 2006-01-24 06:06:11 +00:00
Neal Norwitz fc76d633e8 - Patch #1400181, fix unicode string formatting to not use the locale.
This is how string objects work.  u'%f' could use , instead of .
  for the decimal point.  Now both strings and unicode always use periods.

This is the code that would break:

import locale
locale.setlocale(locale.LC_NUMERIC, 'de_DE')
u'%.1f' % 1.0
assert '1.0' == u'%.1f' % 1.0

I couldn't create a test case which fails, but this fixes the problem.

Will backport.

Armin Rigo fd163f92ce SF patch #1390657:
* set sq_repeat and sq_concat to NULL for user-defined new-style
  classes, as a way to fix a number of related problems.  See
  test_descr.notimplemented()).  One of these problems was fixed
  in r25556 and r25557 but many more existed; this is a general
  fix and thus reverts r25556-r25557.

* to avoid having PySequence_Repeat()/PySequence_Concat() failing
  on user-defined classes, they now fall back to nb_add/nb_mul if
  sq_concat/sq_repeat are not defined and the arguments appear to
  be sequences.

* added tests.

Backport candidate.

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Guido van Rossum 630db60a55 - On 64-bit platforms, when __len__() returns a value that cannot be
represented as a C int, raise OverflowError.

(Forward port from 2.4.2; the patch to classobject.c was already in

2005-09-20 18:49:54 +00:00
Guido van Rossum ba3e6ec0c9 A minor fix for 64-bit platforms: when __len__() returns Python int

rather than truncating silently (and having 50% chance of hitting the
"it should be >= 0" error).

Raymond Hettinger f408ddf4a0 Results of a line-by-line comparison back to dictobject.c.
* set_merge() cannot assume that the table doesn't resize during iteration.

* convert some unnecessary tests to asserts -- they were necessary in
  dictobject.c because PyDict_Next() is a public function.  The same is
  not true for set_next().

* re-arrange the order of functions to more closely match the order
  in dictobject.c.  This makes it must easier to compare the two
  and ought to simplify any issues of maintaining both.

Phillip J. Eby 00148226df Fix a too-aggressive assert (see SF#1257960). Previously, gen_iternext
was never called during interpreter shutdown GC, so the f_back!=NULL
assertion was correct.  Now that generators get close()d during GC,
the assertion was being triggered because the generator close() was being
called as the top-level frame.  However, nothing actually is broken by
this; it's just that the condition was unexpected in previous Python
versions.
2005-08-13 03:29:00 +00:00
Raymond Hettinger b02c35e208 * Fix SF #1257731. Make __contains__(), remove(), and discard() only do

* Eliminate a duplicate if-stmt.

Raymond Hettinger c991db240c * Add short-circuit code for in-place operations with self (such as
s|=s, s&=s, s-=s, or s^=s).  Add related tests.

* Improve names for several variables and functions.

* Provide alternate table access functions (next, contains, add, and discard)
  that work with an entry argument instead of just a key.  This improves
  set-vs-set operations because we already have a hash value for each key
  and can avoid unnecessary calls to PyObject_Hash().  Provides a 5% to 20%
  speed-up for quick hashing elements like strings and integers.  Provides
  much more substantial improvements for slow hashing elements like tuples
  or objects defining a custom __hash__() function.

* Have difference operations resize() when 1/5 of the elements are dummies.
  Formerly, it was 1/6.  The new ratio triggers less frequently and only
  in cases that it can resize quicker and with greater benefit.  The right
  answer is probably either 1/4, 1/5, or 1/6.  Picked the middle value for
  an even trade-off between resize time and the space/time costs of dummy
  entries.
2005-08-11 07:58:45 +00:00
Raymond Hettinger bc841a1464 * Bring in INIT_NONZERO_SET_SLOTS macro from dictionary code.
* Bring in free list from dictionary code.
* Improve several comments.

  1/6 are dummies, then resize them away.
* Factor-out common code with new macro, PyAnySet_CheckExact.
2005-08-07 13:02:53 +00:00
Raymond Hettinger 99220fabb1 * Removed checked_error flag which no longer provides any benefit.

Raymond Hettinger 5ba0cbe392 * set_new() doesn't need to zero the structure a second time after tp_alloc

Raymond Hettinger a580c47c6d * Improve a variable name: entry0 --> table.
* Give set_lookkey_string() a fast alternate path when no dummy entries
  are present.
* Have set_swap_bodies() reset the hash field to -1 whenever either of
  bodies is not a frozenset.  Maintains the invariant of regular sets
  always having -1 in the hash field; otherwise, any mutation would make
  the hash value invalid.
* Use an entry pointer to simplify the code in frozenset_hash().
2005-08-05 17:19:54 +00:00
Raymond Hettinger a9d9936d10 * Move copyright notice to top and indicate derivation from sets.py and

* Finalize the dummy entry before a system exit.

Michael W. Hudson ba283e2b7f This is my patch:
[ 1181301 ] make float packing copy bytes when they can

which hasn't been reviewed, despite numerous threats to check it in
anyway if noone reviews it.  Please read the diff on the checkin list,
at least!

The basic idea is to examine the bytes of some 'probe values' to see if
the current platform is a IEEE 754-ish platform, and if so
_PyFloat_{Pack,Unpack}{4,8} just copy bytes around.

The rest is hair for testing, and tests.

Backported to 2.4.

Raymond Hettinger 57e7447c44 * Beef-up tests for str.count().
* Speed-up str.count() by using memchr() to fly between first char matches.

Raymond Hettinger 7cbf1bcb3e * Beef-up testing of str.__contains__() and str.find().
* Speed-up "x in y" where x has more than one character.

The existing code made excessive calls to the expensive memcmp() function.
The new code uses memchr() to rapidly find a start point for memcmp().
In addition to knowing that the first character is a match, the new code
also checks that the last character is a match.  This significantly reduces
the incidence of false starts (saving memcmp() calls and making quadratic
behavior less likely).

Improves the timings on:
    python -m timeit -r7 -s"x='a'*1000" "'ab' in x"
    python -m timeit -r7 -s"x='a'*1000" "'bc' in x"

Once this code has proven itself, then string_find_internal() should refer
to it rather than running its own version.  Also, something similar may
apply to unicode objects.

Michael W. Hudson ee319f66ab Fix
[ 1124295 ] Function's __name__ no longer accessible in restricted mode

which I introduced with a bit of mindless copy-paste when making
__name__ writable.  You can't assign to __name__ in restricted mode,
which I'm going to pretend was intentional :)

Michael W. Hudson faa7648ffe More bug #1077106 stuff, sorry -- modem induced impatiece!
This should go on whatever bugfix branches the other fetches up on.

Armin Rigo a174813113 Dima Dorfman's patch for coercion/comparison of C types (patch #995939), with
a minor change after the coercion, to accept two objects not necessarily of
the same type but with the same tp_compare.
