Tim Peters 59c9a645e2 SF bug [#460467] file objects should be subclassable.
Preliminary support.  What's here works, but needs fine-tuning.

Tim Peters 16a77adfbd Generalize operator.indexOf (PySequence_Index) to work with any
iterable object.  I'm not sure how that got overlooked before!

Got rid of the internal _PySequence_IterContains, introduced a new
internal _PySequence_IterSearch, and rewrote all the iteration-based
"count of", "index of", and "is the object in it or not?" routines to
just call the new function.  I suppose it's slower this way, but the
code duplication was getting depressing.

Martin v. Löwis cb227c9850 Report patch #416079 changes. 2001-09-06 08:54:16 +00:00
Tim Peters 6e13a562ae Enable large file support on Win32 systems.
Curious:  the MS docs say stati64 etc are supported even on Win95, but
Win95 doesn't support a filesystem that allows partitions > 2 Gb.

test_largefile:  This was opening its test file in text mode.  I have no
idea how that worked under Win64, but it sure needs binary mode on Win98.
BTW, on Win98 test_largefile runs quickly (under a second).
2001-09-06 00:32:15 +00:00
Tim Peters a40c793d06 Rework the way we try to check for libm overflow, given that C99 no longer
requires that errno ever get set, and it looks like glibc is already
playing that game.  New rules:

+ Never use HUGE_VAL.  Use the new Py_HUGE_VAL instead.

+ Never believe errno.  If overflow is the only thing you're interested in,
  use the new Py_OVERFLOWED(x) macro.  If you're interested in any libm
  errors, use the new Py_SET_ERANGE_IF_OVERFLOW(x) macro, which attempts
  to set errno the way C89 said it worked.

Unfortunately, none of these are reliable, but they work on Windows and I
*expect* under glibc too.

Martin v. Löwis 44f8696171 Patch #428326: New class threading.Timer. 2001-09-05 13:44:54 +00:00
Tim Peters 785261684e Return reasonable results for math.log(long) and math.log10(long) (we were
getting Infs, NaNs, or nonsense in 2.1 and before; in yesterday's CVS we
were getting OverflowError; but these functions always make good sense
for positive arguments, no matter how large).
2001-09-05 00:53:45 +00:00
Tim Peters 7eea37e831 At Guido's suggestion, here's a new C API function, PyObject_Dir(), like
__builtin__.dir().  Moved the guts from bltinmodule.c to object.c.
2001-09-04 22:08:56 +00:00
Tim Peters 9fffa3eea3 Raise OverflowError when appropriate on long->float conversion. Most of
the fiddling is simply due to that no caller of PyLong_AsDouble ever
checked for failure (so that's fixing old bugs).  PyLong_AsDouble is much
faster for big inputs now too, but that's more of a happy consequence
than a design goal.

Guido van Rossum 61c345fa37 Rename the -D option to -Q, to avoid a Jython option name conflict. 2001-09-04 03:26:15 +00:00
Tim Peters 32f453eaa4 New restriction on pow(x, y, z): If z is not None, x and y must be of
integer types, and y must be >= 0.  See discussion at

2001-09-03 08:35:41 +00:00
Tim Peters 5d2b77cf31 Make dir() wordier (see the new docstring). The new behavior is a mixed
bag.  It's clearly wrong for classic classes, at heart because a classic
class doesn't have a __class__ attribute, and I'm unclear on whether
that's feature or bug.  I'll repair this once I find out (in the
meantime, dir() applied to classic classes won't find the base classes,
while dir() applied to a classic-class instance *will* find the base
classes but not *their* base classes).

Please give the new dir() a try and see whether you love it or hate it.
The new dir([]) behavior is something I could come to love.  Here's
something to hate:

>>> class C:
...     pass
...
>>> c = C()
>>> dir(c)
['__doc__', '__module__']
>>>

The idea that an instance has a __doc__ attribute is jarring (of course
it's really c.__class__.__doc__ == C.__doc__; likewise for __module__).

OTOH, the code already has too many special cases, and dir(x) doesn't
have a compelling or clear purpose when x isn't a module.

Barry Warsaw 9b3be7f5d9 Document the new semantics for setting and deleting a function's
__dict__ attribute.  Deleting it, or setting it to a non-dictionary
result in a TypeError.  Note that getting it the first time magically
initializes it to an empty dict so that func.__dict__ will always
appear to be a dictionary (never None).

Closes SF bug #446645.

Guido van Rossum c7e4aca56c Add xmlrpc.
(Tim & I should agree on where to add new additions: I add them at the
top, Tim adds them at the bottom.  I like the top better because folks
who occasionally check out the NEWS file will see the latest news
first.)
2001-07-12 11:54:37 +00:00
Barry Warsaw 19b1c6156b (py-version): Hopefully fixed my XEmacs settings so this doesn't get

Tim Peters 7a3bfc3a47 Added q/Q standard (x-platform 8-byte ints) mode in struct module.
This completes the q/Q project.

longobject.c _PyLong_AsByteArray:  The original code had a gross bug:
the most-significant Python digit doesn't necessarily have SHIFT
significant bits, and you really need to count how many copies of the sign
bit it has else spurious overflow errors result.

test_struct.py:  This now does exhaustive std q/Q testing at, and on both
sides of, all relevant power-of-2 boundaries, both positive and negative.

NEWS:  Added brief dict news while I was at it.
2001-06-12 01:22:22 +00:00
Tim Peters 7b9542a3f7 Initial support for 'q' and 'Q' struct format codes: for now, only in
native mode, and only when config #defines HAVE_LONG_LONG.  Standard mode
will eventually treat them as 8-byte ints across all platforms, but that
likely requires a new set of routines in longobject.c first (while
sizeof(long) >= 4 is guaranteed by C, there's nothing in C we can rely
on x-platform to hold 8 bytes of int, so we'll have to roll our own;
I'm thinking of a simple pair of conversion functions, Python long
to/from sized vector of unsigned bytes; that may be useful for GMP
conversions too; std q/Q would call them with size fixed at 8).

test_struct.py:  In addition to adding some native-mode 'q' and 'Q' tests,
got rid of unused code, and repaired a non-portable assumption about
native sizeof(short) (it isn't 2 on some Cray boxes).

libstruct.tex:  In addition to adding a bit of 'q'/'Q' docs (more needed
later), removed an erroneous footnote about 'I' behavior.
2001-06-10 23:40:19 +00:00
Tim Peters 2a7f384122 SF bug 430991: wrong co_lnotab
Armin Rigo pointed out that the way the line-# table got built didn't work
for lines generating more than 255 bytes of bytecode.  Fixed as he
suggested, plus corresponding changes to pyassem.py, plus added some
long overdue docs about this subtle table to compile.c.

Bugfix candidate (line numbers may be off in tracebacks under -O).

2001-06-02 06:16:02 +00:00
Tim Peters eb28ef209e New collision resolution scheme: no polynomials, simpler, faster, less
code, less memory.  Tests have uncovered no drawbacks.  Christian and
Vladimir are the other two people who have burned many brain cells on the
dict code in recent years, and they like the approach too, so I'm checking
it in without further ado.
2001-06-02 05:27:19 +00:00
Tim Peters 4324aa3572 Cruft cleanup: Removed the unused last_is_sticky argument from the internal
_PyTuple_Resize().
2001-05-28 22:30:08 +00:00
Tim Peters 15d4929ae4 Implement an old idea of Christian Tismer's: use polynomial division
instead of multiplication to generate the probe sequence.  The idea is
recorded in Python-Dev for Dec 2000, but that version is prone to rare
infinite loops.

The value is in getting *all* the bits of the hash code to participate;
and, e.g., this speeds up querying every key in a dict with keys
 [i << 16 for i in range(20000)] by a factor of 500.  Should be equally
valuable in any bad case where the high-order hash bits were getting
ignored.

Also wrote up some of the motivations behind Python's ever-more-subtle
hash table strategy.
2001-05-27 07:39:22 +00:00
Tim Peters 1af03e98d9 Change list.extend() error msgs and NEWS to reflect that list.extend()

Tim Peters 58e0a8c130 SF patch #418147 Fixes to allow compiling w/ Borland, from Stephen Hansen. 2001-05-14 22:32:33 +00:00
Tim Peters 95b3f78622 pprint's workhorse _safe_repr() function took time quadratic in the # of
elements when crunching a list, dict or tuple.  Now takes linear time
instead -- huge speedup for even moderately large containers, and the
code is notably simpler too.
Added some basic "is the output correct?" tests to test_pprint.

Tim Peters 2f228e75e4 Get rid of the superstitious "~" in dict hashing's "i = (~hash) & mask".
The comment following used to say:
	/* We use ~hash instead of hash, as degenerate hash functions, such
	   as for ints <sigh>, can have lots of leading zeros. It's not
	   really a performance risk, but better safe than sorry.
	   12-Dec-00 tim:  so ~hash produces lots of leading ones instead --
	   what's the gain? */
That is, there was never a good reason for doing it.  And to the contrary,
as explained on Python-Dev last December, it tended to make the *sum*
(i + incr) & mask (which is the first table index examined in case of
collison) the same "too often" across distinct hashes.

Changing to the simpler "i = hash & mask" reduced the number of string-dict
collisions (== # number of times we go around the lookup for-loop) from about
6 million to 5 million during a full run of the test suite (these are
approximate because the test suite does some random stuff from run to run).
The number of collisions in non-string dicts also decreased, but not as
dramatically.

Note that this may, for a given dict, change the order (wrt previous
releases) of entries exposed by .keys(), .values() and .items().  A number
of std tests suffered bogus failures as a result.  For dicts keyed by
small ints, or (less so) by characters, the order is much more likely to be
in increasing order of key now; e.g.,

>>> d = {}
>>> for i in range(10):
...    d[i] = i
...
>>> d
{0: 0, 1: 1, 2: 2, 3: 3, 4: 4, 5: 5, 6: 6, 7: 7, 8: 8, 9: 9}
>>>

Unfortunately. people may latch on to that in small examples and draw a
bogus conclusion.

test_support.py
    Moved test_extcall's sortdict() into test_support, made it stronger,
    and imported sortdict into other std tests that needed it.
test_unicode.py
    Excluced cp875 from the "roundtrip over range(128)" test, because
    cp875 doesn't have a well-defined inverse for unicode("?", "cp875").
    See Python-Dev for excruciating details.
Cookie.py
    Chaged various output functions to sort dicts before building
    strings from them.
test_extcall
    Fiddled the expected-result file.  This remains sensitive to native
    dict ordering, because, e.g., if there are multiple errors in a
    keyword-arg dict (and test_extcall sets up many cases like that), the
    specific error Python complains about first depends on native dict
    ordering.

Tim Peters 8572b4fedf Generalize zip() to work with iterators.
NEEDS DOC CHANGES.
More AttributeErrors transmuted into TypeErrors, in test_b2.py, and,
again, this strikes me as a good thing.
This checkin completes the iterator generalization work that obviously
needed to be done.  Can anyone think of others that should be changed?

Tim Peters de9725f135 Make 'x in y' and 'x not in y' (PySequence_Contains) play nice w/ iterators.
NEEDS DOC CHANGES
A few more AttributeErrors turned into TypeErrors, but in test_contains
this time.
The full story for instance objects is pretty much unexplainable, because
instance_contains() tries its own flavor of iteration-based containment
testing first, and PySequence_Contains doesn't get a chance at it unless
instance_contains() blows up.  A consequence is that
    some_complex_number in some_instance
dies with a TypeError unless some_instance.__class__ defines __iter__ but
does not define __getitem__.
2001-05-05 10:06:17 +00:00
Tim Peters 2cfe368283 Make unicode.join() work nice with iterators. This also required a change
to string.join(), so that when the latter figures out in midstream that
it really needs unicode.join() instead, unicode.join() can actually get
all the sequence elements (i.e., there's no guarantee that the sequence
passed to string.join() can be iterated over *again* by unicode.join(),
so string.join() must not pass on the original sequence object anymore).
2001-05-05 05:36:48 +00:00
Tim Peters 432b42aa4c Mark string.join() as done. Turns out string_join() works "for free" now,
because PySequence_Fast() started working for free as soon as
PySequence_Tuple() learned how to work with iterators.  For some reason
unicode.join() still doesn't work, though.
2001-05-05 04:24:43 +00:00
Tim Peters 6912d4ddf0 Generalize tuple() to work nicely with iterators.
NEEDS DOC CHANGES.
This one surprised me!  While I expected tuple() to be a no-brainer, turns
out it's actually dripping with consequences:
1. It will *allow* the popular PySequence_Fast() to work with any iterable
   object (code for that not yet checked in, but should be trivial).
2. It caused two std tests to fail.  This because some places used
   PyTuple_Sequence() (the C spelling of tuple()) as an indirect way to test
   whether something *is* a sequence.  But tuple() code only looked for the
   existence of sq->item to determine that, and e.g. an instance passed
   that test whether or not it supported the other operations tuple()
   needed (e.g., __len__).  So some things the tests *expected* to fail
   with an AttributeError now fail with a TypeError instead.  This looks
   like an improvement to me; e.g., test_coercion used to produce 559
   TypeErrors and 2 AttributeErrors, and now they're all TypeErrors.  The
   error details are more informative too, because the places calling this
   were *looking* for TypeErrors in order to replace the generic tuple()
   "not a sequence" msg with their own more specific text, and
   AttributeErrors snuck by that.

2001-05-04 04:39:21 +00:00
Tim Peters 4e9afdca39 Generalize map() to work with iterators.
NEEDS DOC CHANGES.
Possibly contentious:  The first time s.next() yields StopIteration (for
a given map argument s) is the last time map() *tries* s.next().  That
is, if other sequence args are longer, s will never again contribute
anything but None values to the result, even if trying s.next() again
could yield another result.  This is the same behavior map() used to have
wrt IndexError, so it's the only way to be wholly backward-compatible.
I'm not a fan of letting StopIteration mean "try again later" anyway.

filter, etc) can be generalized similarly.  Feel encouraged to grab your
favorite and convert it!

    list(xrange(i, j, k)) == range(i, j, k)

Fred Drake 4e262a9631 A small change to the C API for weakly-referencable types: Such types
must now initialize the extra field used by the weak-ref machinery to
NULL themselves, to avoid having to require PyObject_INIT() to check
if the type supports weak references and do it there.  This causes less
work to be done for all objects (the type object does not need to be
consulted to check for the Py_TPFLAGS_HAVE_WEAKREFS bit).

SF patch http://sourceforge.net/patch/?func=detailpatch&patch_id=103453&group_id=5470
PyMember_Set of T_CHAR always raises exception.
Unfortunately, this is a use of a C API function that Python itself never makes, so
there's no .py test I can check in to verify this stays fixed.  But the fault in the
code is obvious, and Dave Cole's patch just as obviously fixes it.
