Guido van Rossum 4f53da07bf Two improvements to large file support:
- In _portable_ftell(), try fgetpos() before ftello() and ftell64().
  I ran into a situation on a 64-bit capable Linux where the C
  library's ftello() and ftell64() returned negative numbers despite
  fpos_t and off_t both being 64-bit types; fgetpos() did the right
  thing.

- Define a new typedef, Py_off_t, which is either fpos_t or off_t,
  depending on which one is 64 bits.  This removes the need for a lot
  of #ifdefs later on.  (XXX Should this be moved to pyport.h?  That
  file currently seems oblivious to large fille support, so for now
  I'll leave it here where it's needed.)

Jeremy Hylton 2b724da8d9 Remove f_closure slot of frameobject and use f_localsplus instead.
This change eliminates an extra malloc/free when a frame with free
variables is created.  Any cell vars or free vars are stored in
f_localsplus after the locals and before the stack.

eval_code2() fills in the appropriate values after handling
initialization of locals.

To track the size the frame has an f_size member that tracks the total
size of f_localsplus. It used to be implicitly f_nlocals + f_stacksize.

Jeremy Hylton 64949cb753 PEP 227 implementation
The majority of the changes are in the compiler.  The mainloop changes
primarily to implement the new opcodes and to pass a function's
closure to eval_code2().  Frames and functions got new slots to hold
the closure.

Include/compile.h
    Add co_freevars and co_cellvars slots to code objects.
    Update PyCode_New() to take freevars and cellvars as arguments
Include/funcobject.h
    Add func_closure slot to function objects.
    Add GetClosure()/SetClosure() functions (and corresponding
    macros) for getting at the closure.
Include/frameobject.h
    PyFrame_New() now takes a closure.
Include/opcode.h
    Add four new opcodes: MAKE_CLOSURE, LOAD_CLOSURE, LOAD_DEREF,
    STORE_DEREF.
    Remove comment about old requirement for opcodes to fit in 7
    bits.
compile.c
    Implement changes to code objects for co_freevars and co_cellvars.

    Modify symbol table to use st_cur_name (string object for the name
    of the current scope) and st_cur_children (list of nested blocks).
    Also define st_nested, which might more properly be called
    st_cur_nested.  Add several DEF_XXX flags to track def-use
    information for free variables.

    New or modified functions of note:
    com_make_closure(struct compiling *, PyCodeObject *)
        Emit LOAD_CLOSURE opcodes as needed to pass cells for free
        variables into nested scope.
    com_addop_varname(struct compiling *, int, char *)
        Emits opcodes for LOAD_DEREF and STORE_DEREF.
    get_ref_type(struct compiling *, char *name)
        Return NAME_CLOSURE if ref type is FREE or CELL
    symtable_load_symbols(struct compiling *)
        Decides what variables are cell or free based on def-use info.
        Can now raise SyntaxError if nested scopes are mixed with
        exec or from blah import *.
    make_scope_info(PyObject *, PyObject *, int, int)
        Helper functions for symtable scope stack.
    symtable_update_free_vars(struct symtable *)
        After a code block has been analyzed, it must check each of
        its children for free variables that are not defined in the
        block.  If a variable is free in a child and not defined in
        the parent, then it is defined by block the enclosing the
        current one or it is a global.  This does the right logic.
    symtable_add_use() is now a macro for symtable_add_def()
    symtable_assign(struct symtable *, node *)
        Use goto instead of for (;;)

    Fixed bug in symtable where name of keyword argument in function
    call was treated as assignment in the scope of the call site. Ex:
        def f():
            g(a=2) # a was considered a local of f

ceval.c
    eval_code2() now take one more argument, a closure.
    Implement LOAD_CLOSURE, LOAD_DEREF, STORE_DEREF, MAKE_CLOSURE>

    Also: When name error occurs for global variable, report that the
    name was global in the error mesage.

Objects/frameobject.c
    Initialize f_closure to be a tuple containing space for cellvars
    and freevars.  f_closure is NULL if neither are present.
Objects/funcobject.c
    Add support for func_closure.
Python/import.c
    Change the magic number.
Python/marshal.c
    Track changes to code objects.

2001-01-23 16:33:18 +00:00
Barry Warsaw 9bf16440f4 A few miscellaneous helpers.
PyObject_Dump(): New function that is useful when debugging Python's C
runtime.  In something like gdb it can be a pain to get some useful
information out of PyObject*'s.  This function prints the str() of the
object to stderr, along with the object's refcount and hex address.

PyGC_Dump(): Similar to PyObject_Dump() but knows how to cast from the
garbage collector prefix back to the PyObject* structure.

[See Misc/gdbinit for some useful gdb hooks]

none_dealloc(): Rather than SEGV if we accidentally decref None out of
existance, we assign None's and NotImplemented's destructor slot to
this function, which just calls abort().

Barry, that comment belongs in the code, not in the checkin msg.
    The code *used* to do this correctly (as you well know, since you
    & I went thru considerable pain to fix this the first time).
    However, because the *reason* for the convolution wasn't recorded
    in the code as a comment, somebody threw it all away the first
    time it got reworked.

default_3way_compare(): Stick the checkin message from 2.110 in a
comment.
2001-01-20 06:24:55 +00:00
Barry Warsaw 71ff8d5dc5 default_3way_compare(): When comparing the pointers, they must be cast
to integer types (i.e. Py_uintptr_t, our spelling of C9X's uintptr_t).
ANSI specifies that pointer compares other than == and != to
non-related structures are undefined.  This quiets an Insure
portability warning.
2001-01-20 06:08:10 +00:00
Barry Warsaw 0395fdd3a9 Application and elaboration of patch #103305 to fix core dumps when
del'ing func.func_dict.  I took the opportunity to also clean up some
other nits with the code, namely core dumps when del'ing func_defaults
and KeyError instead of AttributeError when del'ing a non-existant
function attribute.

Specifically,

func_memberlist: Move func_dict and __dict__ into here instead of
special casing them in the setattro and getattro methods.  I don't
remember why I took them out of here before I first uploaded the PEP
232 patch. :/

func_getattro(): No need to special case __dict__/func_dict since
their now in the func_memberlist and PyMember_Get() should Do The
Right Thing (i.e. transforms NULL values into Py_None).

func_setattro(): Document the intended behavior of del'ing or setting
to None one of the special func_* attributes.  I.e.:

    func_code - can only be set to a code object.  It can't be del'd
    or set to None.

    func_defaults - can be del'd.  Can only be set to None or a tuple.

    func_dict - can be del'd.  Can only be set to None or a
    dictionary.

Fix core dumps and incorrect exceptions as described above.  Also, if
we're del'ing an arbitrary function attribute but func_dict is NULL,
don't create func_dict before discovering that we'll get an
AttributeError anyway.

Tim Peters 19fe14e76a Derivative of patch #102549, "simpler, faster(!) implementation of string.join".
Also fixes two long-standing bugs (present in 2.0):
1. .join() didn't check that the result size fit in an int.
2. string.join(s) when len(s)==1 returned s[0] regardless of s[0]'s
   type; e.g., "".join([3]) returned 3 (overly optimistic optimization).
I resisted a keen temptation to make .join() apply str() automagically.

Guido van Rossum a3af41d564 Changes to recursive-object comparisons, having to do with a test case
I found where rich comparison of unequal recursive objects gave
unintuituve results.  In a discussion with Tim, where we discovered
that our intuition on when a<=b should be true was failing, we decided
to outlaw ordering comparisons on recursive objects.  (Once we have
fixed our intuition and designed a matching algorithm that's practical
and reasonable to implement, we can allow such orderings again.)

- Refactored the recursive-object comparison framework; more is now
  done in the support routines so less needs to be done in the calling
  routines (even at the expense of slowing it down a bit -- this
  should normally never be invoked, it's mostly just there to avoid
  blowing up the interpreter).

- Changed the framework so that the comparison operator used is also
  stored.  (The dictionary now stores triples (v, w, op) instead of
  pairs (v, w).)

- Changed the nesting limit to a more reasonable small 20; this only
  slows down comparisons of very deeply nested objects (unlikely to
  occur in practice), while speeding up comparisons of recursive
  objects (previously, this would first waste time and space on 500
  nested comparisons before it would start detecting recursion).

- Changed rich comparisons for recursive objects to raise a ValueError
  exception when recursion is detected for ordering oprators (<, <=,
  >, >=).

Unrelated change:

- Moved PyObject_Unicode() to just under PyObject_Str(), where it
  belongs.  MAL's patch must've inserted in a random spot between two
  functions in the file -- between two helpers for rich comparison...

Tim Peters 60f42b50d8 Move distributed and duplicated config for stat() and fstat() into pyport.h. 2001-01-18 03:03:16 +00:00
Guido van Rossum be4cbb1668 Use rich comparisons to fulfill an old wish: complex numbers now raise
exceptions when compared using <, <=, > or >=.

NOTE: This is a tentative change: this means that cmp() involving
complex numbers will raise an exception when the numbers differ, and
that in turn means that e.g. dictionaries and certain other compounds
(e.g. UserLists) containing complex numbers can't be compared either.
So we'll have to decide whether this is acceptable.  The alpha test
cycle is a good time to keep an eye on this!
2001-01-18 01:12:39 +00:00
Guido van Rossum b932420cc7 Rich comparisons:
- Use PyObject_RichCompareBool() when comparing keys; this makes the
  error handling cleaner.

- There were two implementations for dictionary comparison, an old one
  (#ifdef'ed out) and a new one.  Got rid of the old one, which was
  abandoned years ago.

- In the characterize() function, part of dictionary comparison, use
  PyObject_RichCompareBool() to compare keys and values instead.  But
  continue to use PyObject_Compare() for comparing the final
  (deciding) elements.

- Align the comments in the type struct initializer.

Note: I don't implement rich comparison for dictionaries -- there
doesn't seem to be much to be gained.  (The existing comparison
already decides that shorter dicts are always smaller than longer
dicts.)
2001-01-18 00:39:02 +00:00
Guido van Rossum f77bc62e73 Same treatment as listobject.c:
- tuplecontains(): call RichCompare(Py_EQ).

- Get rid of tuplecompare(), in favor of new tuplerichcompare() (a
  clone of list_compare()).

- Aligned the comments for large struct initializers.
2001-01-18 00:00:53 +00:00
Guido van Rossum 24f67d568c Fix a leak in instance_coerce(). This was introduced by Neil's
earlier coercion changes, not by rich comparisons.  When a coercion
function returns 1 (meaning it cannot do it), it should not INCREF the
arguments.  When no __coerce__() method was found, instance_coerce()
originally returned 0, pretending it did it.  Neil changed the return
value to 1, more accurately reflecting that it didn't do anything, but
forgot to take out the two INCREF calls.
2001-01-17 23:43:43 +00:00
Guido van Rossum 65e1cea6e3 Convert to rich comparisons:
- sort's docompare() calls RichCompare(Py_LT).

- list_contains(), list_index(), listcount(), listremove() call
  RichCompare(Py_EQ).

- Get rid of list_compare(), in favor of new list_richcompare().  The
  latter does some nice shortcuts, like when == or != is requested, it
  first compares the lengths for trivial accept/reject.  Then it goes
  over the items until it finds an index where the items differe; then
  it does more shortcut magic to minimize the number of additional
  comparisons.

- Aligned the comments for large struct initializers.
2001-01-17 22:11:59 +00:00
Guido van Rossum 2ffbf6b112 Deal properly (?) with comparing recursive datastructures.
- Use the compare nesting level and in-progress dictionary properly in
  PyObject_RichCompare().

- Change the in-progress code to use static variables instead of
  globals (both the nesting level and the key for the thread dict were
  globals but have no reason to be globals; the key can even be a
  function-static variable in get_inprogress_dict()).

- Rewrote try_rich_to_3way_compare() to benefit from the similarity of
  the three cases, making it table-driven.

- In try_rich_to_3way_compare(), test for EQ before LT and GT.  This
  turns out essential when comparing recursive UserList instances;
  with the old code, these would recurse into rich comparison three
  times for each nesting level up to NESTING_LIMIT/2, making the total
  number of calls in the order of 3**(NESTING_LIMIT/2)!

NOTE: I'm not 100% comfortable with this.  It works for the standard
test suite (which compares a few trivial recursive data structures
only), but I'm not sure that the in-progress dictionary is used
properly by the rich comparison code.  Jeremy suggested that maybe the
operation should be included in the dict.  Currently I presume that
objects in the dict are equal unless proven otherwise, and I set the
outcome for the rich comparison accordingly: true for operators EQ,
LE, GE, and false for the other three.  But Jeremy seems to think that
there may be counter-examples where this doesn't do the right thing.

for .count(), .startswith() and .endswith() for the case of
mixed string/Unicode objects.

This patch adds Python style index semantics to PyUnicode_Count()
indices (including the special handling of negative indices).

The patch is an extended version of patch #103249 submitted
by Michael Hudson (mwh) on SF. It also includes new test cases.

Barry Warsaw d6a9e84c81 Committing PEP 232, function attribute feature, approved by Guido.
Closes SF patch #103123.

funcobject.h:

    PyFunctionObject: add the func_dict slot.

funcobject.c:

    PyFunction_New(): Initialize the func_dict slot to NULL.

    func_getattr(): Rename to func_getattro() and change the
    signature.  It's more efficient to use attro methods and dig the C
    string out than it is to re-convert a C string to a PyString.

    Also, add support for getting the __dict__ (a.k.a. func_dict)
    attribute, and for getting an arbitrary function attribute.

    func_setattr(): Rename to func_setattro() and change the signature
    for the same reason.  Also add support for setting __dict__
    (a.k.a. func_dict) and any arbitrary function attribute.

    func_dealloc(): Be sure to DECREF the func_dict slot.

    func_traverse(): Be sure to traverse func_dict too.

    PyFunction_Type: make the necessary func_?etattro() changes.

classobject.c:

    instancemethod_memberlist: Add __dict__

    instancemethod_setattro(): New method to set arbitrary attributes
    on methods (really the underlying im_func).  Raise TypeError when
    the instance is bound or when you're trying to set one of the
    reserved im_* attributes.

    instancemethod_getattr(): Renamed to instancemethod_getattro()
    since that's what it really is.  Also, added support fo getting
    arbitrary attributes through the im_func.

    PyMethod_Type: Do the ?etattr{,o} dance.

Guido van Rossum 65e0b99b61 SF patch #103158 by Greg Ball: Don't do unsafe arithmetic in xrange
object.

This fixes potential overflows in xrange()'s internal calculations on
64-bit platforms.  The fix is complicated because the sq_length slot
function can only return an int; we want to support
xrange(sys.maxint), which is a 64-bit quantity on most 64-bit
platforms (except Win64).  The solution is hacky but the best
possible: when the range is that long, we can use it in a for loop but
we can't ask for its length (nor can we actually iterate beyond
2**31-1, because the sq_item slot function has the same restrictions
on its arguments.  Fixing those restrictions is a project for another
day...

Tim Peters 142297ac92 Speed getline_via_fgets(), by supplying two "fast paths", although one is
faster than the other.  Should be faster for Mark Favas's 254-character
mail log lines, and *is* 3-4% quicker for my test case with much shorter
lines (but they're typical of *my* text files, and I'm tired of optimizing
for everyone else at my expense <wink> -- in fact, the only one who loses
here is Guido ...).

Guido van Rossum 8628206b95 Let's hope that three time's a charm...
Tim discovered another "bug" in my get_line() code: while the comments
said that n<0 was invalid, it was in fact still called with n<0 (when
PyFile_GetLine() was called with n<0).  In that case fortunately
executed the same code as for n==0.

Changed the comment to admit this fact, and changed Tim's MS speed
hack code to use 'n <= 0' as the criteria for the speed hack.
2001-01-08 01:26:47 +00:00
Tim Peters 15b838521f Fiddled ms_getline_hack after talking w/ Guido: made clearer that the
code duplication is to let us get away without a realloc whenever possible;
boosted the init buf size (the cutoff at which we *can* get away without
a realloc) from 100 to 200 so that more files can enjoy this boost; and
allowed other threads to run in all cases.  The last two cost something,
but not significantly:  in my fat test case, less than a 1% slowdown total.
Since my test case has a great many short lines, that's probably the worst
slowdown, too.  While the logic barely changed, there were lots of edits.
This also gets rid of the reference to fp->_cnt, so the last platform
assumption being made here is that fgets doesn't overwrite bytes
capriciously (== beyond the terminating null byte it must write).

Tim Peters 86821b2563 MS Win32 .readline() speedup, as discussed on Python-Dev. This is a tricky
variant that never needs to "search from the right".

Guido van Rossum 4ddf0a01f7 Tim noticed that I had botched get_line_raw(). Looking again, I
realized that this behavior is already present in PyFile_GetLine(),
which is the only place that needs it.  A little refactoring of that
function made get_line_raw() redundant.
2001-01-07 20:51:39 +00:00
Marc-André Lemburg ec233e5803 This patch adds a new feature to the builtin charmap codec:
The mapping dictionaries can now contain 1-n mappings, meaning
that character ordinals may be mapped to strings or Unicode object,
e.g. 0x0078 ('x') -> u"abc", causing the ordinal to be replaced by
the complete string or Unicode object instead of just one character.

Another feature introduced by the patch is that of mapping oridnals to
the emtpy string. This allows removing characters.

The patch is different from patch #103100 in that it does not cause a
performance hit for the normal use case of 1-1 mappings.

Marc-André Lemburg a866df806d This patch changes the default behaviour of the builtin charmap
codec to not apply Latin-1 mappings for keys which are not found
in the mapping dictionaries, but instead treat them as undefined
mappings.

The patch was originally written by Martin v. Loewis with some
additional (cosmetic) changes and an updated test script
by Marc-Andre Lemburg.

The standard codecs were recreated from the most current files
available at the Unicode.org site using the Tools/scripts/gencodec.py
tool.

Tim Peters c54d19043a SF bug 115831 and Ping's SF patch 101751, 0.0**-2.0 returns inf rather than
raise ValueError.  Checked in the patch as far as it went, but also changed
all of ints, longs and floats to raise ZeroDivisionError instead when raising
0 to a negative number.  This is what 754-inspired stds require, as the "true
result" is an infinity obtained from finite operands, i.e. it's a singularity.
Also changed float pow to not be so timid about using its square-and-multiply
algorithm.  Note that what math.pow does is unrelated to what builtin pow
does, and will still vary by platform.

Tim Peters ef14d73b7a Fix for SF bug 110624: float literals behave inconsistently.
I fixed the specific complaint but left the (many) large issues untouched.
See the (very long) bug report discussion for why:
    http://sourceforge.net/bugs/?func=detailbug&group_id=5470&bug_id=110624
Note that while I left the interface to the undocumented public API function
PyFloat_FromString alone, its 2nd argument is useless.  From a comment block
in the code:

RED_FLAG 22-Sep-2000 tim
PyFloat_FromString's pend argument is braindead.  Prior to this RED_FLAG,

1.  If v was a regular string, *pend was set to point to its terminating
    null byte.  That's useless (the caller can find that without any
    help from this function!).

2.  If v was a Unicode string, or an object convertible to a character
    buffer, *pend was set to point into stack trash (the auto temp
    vector holding the character buffer).  That was downright dangerous.

Since we can't change the interface of a public API function, pend is
still supported but now *officially* useless:  if pend is not NULL,
*pend is set to NULL.

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.
2000-09-21 05:43:11 +00:00
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.
2000-09-19 21:04:18 +00:00
Marc-André Lemburg e44e507b0e PyObject_SetAttr() and PyObject_GetAttr() now also accept Unicode
objects for the attribute name. Unicode objects are converted to
a string using the default encoding before trying the lookup.

Note that previously it was allowed to pass arbitrary objects as
attribute name in case the tp_getattro/setattro slots were defined.
This patch fixes this by applying an explicit string check first:
all uses of these slots expect string objects and do not check
for the type resulting in a core dump. The tp_getattro/setattro
are still useful as optimization for lookups using interned
string objects though.

This patch fixes bug #113829.

that Py_INCREF boosts global _Py_RefTotal when Py_REF_DEBUG is defined

There are, IMO, way too many preprocessor gimmicks in use for refcount
debugging (at least 3 distinct true/false symbols, but not all 8 combos
are supported by the code, etc etc), and no coherent documentation of
this stuff -- 'twas too painful to track this one down.

Jeremy Hylton b709df3810 refactor __del__ exception handler into PyErr_WriteUnraisable
add sanity check to gc: if an exception occurs during GC, call
PyErr_WriteUnraisable and then call Py_FatalEror.

Guido van Rossum 04127de434 Add parens suggested by gcc -Wall. 2000-09-01 02:39:00 +00:00
Fred Drake 1bff34ab96 Slight performance hack that also avoids requiring the existence of thread
state for dictionaries that have only been indexed by string keys.

See the comments in SourceForge for more.

This closes SourceForge patch #101309.
2000-08-31 19:31:38 +00:00
Fred Drake c88b99ce06 Clear errors raised by PyObject_Compare() without losing any existing
exception context.  This avoids improperly propogating errors raised by
a user-defined __cmp__() by a subsequent lookup operation.

This patch does *not* include the performance enhancement patch for
dictionaries with string keys only; that will be checked in separately.

This closes SourceForge patch #101277 and bug #112558.
2000-08-31 19:04:07 +00:00
Thomas Wouters 6b958f7d7b Fix grouping: this is how I intended it, misguided as I was in boolean

Fred Drake 8ce159aef5 Peter Schneider-Kamp <nowonder@nowonder.de>:
Remove some of GCC's warning in -Wstrict-prototypes mode.

This closes SourceForge patch #101342.
2000-08-31 05:18:54 +00:00
Fred Drake 562f62aa9b Removed compiler warning about wanting explicit grouping around &&
expression next to a || expression; this is a readability-inspired
warning from GCC.

Marc-André Lemburg f5e96fa6b7 Fixed a serious typo. 2000-08-25 22:49:05 +00:00
Marc-André Lemburg 6ef68b5b01 Fix to bug [ Bug #111860 ] file.writelines() crashes.
file.writelines() now tries to emulate the behaviour of file.write()
as closely as possible. Due to the problems with releasing the
interpreter lock the solution isn't exactly optimal, but still better
than not supporting the file.write() semantics at all.

Thomas Wouters 1de2a79a48 Call PyErr_Clear() to clear the AttributeError raised by GetAttr. 2000-08-25 10:47:46 +00:00
Thomas Wouters e289e0bd0c Support for the in-place operations introduced by augmented assignment. Only
the list object supports this currently, but other candidates are
gladly accepted (like arraymodule and such.)
2000-08-24 20:08:19 +00:00
Thomas Wouters e266e42c9c Addendum to previous change: now that 'f' is not unconditionally
initialized in the 'if (..)', do so manually.
2000-08-23 23:31:34 +00:00
Thomas Wouters bf6cfa5f8e Add extra check on whether 'tp_as_number' is still non-NULL after coercion,
in the PyNumber_* functions. Also, remove unnecessary tests from
PyNumber_Multiply: after BINOP(), neither argument can be an instance.
2000-08-23 23:16:10 +00:00
Jack Jansen d49cbe1060 Added PyOS_CheckStack call to PyObject_Compare
Lowered the recursion limit on compares to 60 (one recursion depth can

Barry Warsaw ce4dc41b1a PyUnicode_AsUTF8String(): /F picks up what I missed: the local var
`str' is no longer necessary.  Gotta turn on -Wall!
2000-08-18 19:30:40 +00:00
Barry Warsaw 2dd4abf277 PyUnicode_AsUTF8String(): Don't need to explicitly incref str since
PyUnicode_EncodeUTF8() already returns the created object with the
proper reference count.  This fixes an Insure reported memory leak.

Barry Warsaw 9d23a4eb03 make_pair(): When comparing the pointers, they must be cast to integer
types (i.e. Py_uintptr_t, our spelling of C9X's uintptr_t).  ANSI
specifies that pointer compares other than == and != to non-related
structures are undefined.  This quiets an Insure portability warning.
2000-08-18 05:01:19 +00:00
Barry Warsaw 67c1a04bbb PyFloat_FromString(): Move s_buffer[] up to the top-level function
scope.  Previously, s_buffer[] was defined inside the
PyUnicode_Check() scope, but referred to in the outer scope via
assignment to s.  This quiets an Insure portability warning.
2000-08-18 05:00:03 +00:00

2000-08-18 04:57:32 +00:00
Thomas Wouters 1d75a79c00 Apply SF patch #101029: call __getitem__ with a proper slice object if there
is no __getslice__ available. Also does the same for C extension types.
Includes rudimentary documentation (it could use a cross reference to the
section on slice objects, I couldn't figure out how to do that) and a test
suite for all Python __hooks__ I could think of, including the new
behaviour.
2000-08-17 22:37:32 +00:00
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.

Tim Peters 39dce29365 Fix for http://sourceforge.net/bugs/?func=detailbug&bug_id=111866&group_id=5470.
This was a misleading bug -- the true "bug" was that hash(x) gave an error
return when x is an infinity.  Fixed that.  Added new Py_IS_INFINITY macro to
pyport.h.  Rearranged code to reduce growing duplication in hashing of float and
complex numbers, pushing Trent's earlier stab at that to a logical conclusion.
Fixed exceedingly rare bug where hashing of floats could return -1 even if there
wasn't an error (didn't waste time trying to construct a test case, it was simply
obvious from the code that it *could* happen).  Improved complex hash so that
hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.
2000-08-15 03:34:48 +00:00
Marc-André Lemburg b7520774e2 Fixed a couple of instances where a 0-length string was being
resized after creation. 0-length strings are usually shared
and _PyString_Resize() fails on these shared strings.

Trent Mick 20abf573ef Clean up warning from Monterey compiler.
Properly end a comment block. It was terminated fine later but by a subsequent
block and. It was also in #if 0. This patch is so trivial I can't believe I am
talking about it. :)
2000-08-12 22:14:34 +00:00
Trent Mick a248fb605f Clean up a warning on Win64. The downcast of the strlen size_t
return value to int is safe here because it previously checked that
there will be no overflow.
2000-08-12 21:37:39 +00:00
Trent Mick 8a74e5fc2c Add the current Win64 compiler to the list of those that need the
huge switch statement broken up. This will probably not be necessary when
the Win64 compiler matures.
2000-08-12 19:37:27 +00:00
Trent Mick f29f47b38b Add largefile support for Linux64 and WIn64. Add test_largefile and some minor
change to regrtest.py to allow optional running of test_largefile ('cause it's

Guido van Rossum 164452cec4 Barry's patch to implement the new setdefault() method. 2000-08-08 16:12:54 +00:00
Marc-André Lemburg e5034378cc Removing UTF-16 aware Unicode comparison code. This kind of compare
function (together with other locale aware ones) should into a new collation
support module. See python-dev for a discussion of this removal.

Note: This patch should also be applied to the 1.6 branch.

Fred Drake c76e0e5679 snprintf() is not portable, so continue to use sprintf() until a portable
snprintf() is available.
2000-08-04 02:34:41 +00:00
Marc-André Lemburg bff879cabb This patch finalizes the move from UTF-8 to a default encoding in
the Python Unicode implementation.

The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).

Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.

(Note: this patch will also have to be applied to the 1.6 branch
 of the CVS tree.)

Marc-André Lemburg fb625847bf Fix to a bug found by Florian Weimer:
The UTF-8 decoder is still buggy (i.e. it doesn't pass Markus Kuhn's
stress test), mainly due to the following construct:

    #define UTF8_ERROR(details)  do {                       \
        if (utf8_decoding_error(&s, &p, errors, details))   \
            goto onError;                                   \
        continue;                                           \
    } while (0)

(The "continue" statement is supposed to exit from the outer loop,
but of course, it doesn't.  Indeed, this is a marvelous example of
the dangers of the C programming language and especially of the C
preprocessor.)

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 ;)
