Tim Peters 58e0a8c130 SF patch #418147 Fixes to allow compiling w/ Borland, from Stephen Hansen. 2001-05-14 22:32:33 +00:00
Mark Hammond 26cffde4c2 Fix the Py_FileSystemDefaultEncoding checkin - declare the variable in a fileobject.h, and initialize it in bltinmodule. 2001-05-14 12:17:34 +00:00
Tim Peters 72f98e9b83 SF bug #422177: Results from .pyc differs from .py
Store floats and doubles to full precision in marshal.
Test that floats read from .pyc/.pyo closely match those read from .py.
Declare PyFloat_AsString() in floatobject header file.
Add new PyFloat_AsReprString() API function.
Document the functions declared in floatobject.h.

Tim Peters cb8d368b82 Reimplement PySequence_Contains() and instance_contains(), so they work
safely together and don't duplicate logic (the common logic was factored
out into new private API function _PySequence_IterContains()).
Visible change:
    some_complex_number  in  some_instance
no longer blows up if some_instance has __getitem__ but neither
__contains__ nor __iter__.  test_iter changed to ensure that remains true.

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.

Tim Peters f4848dac41 Make PyIter_Next() a little smarter (wrt its knowledge of iterator
internals) so clients can be a lot dumber (wrt their knowledge).
2001-05-05 00:14:56 +00:00
Marc-André Lemburg 8155e0e541 This patch originated from an idea by Martin v. Loewis who submitted a
patch for sharing single character Unicode objects.

Martin's patch had to be reworked in a number of ways to take Unicode
resizing into consideration as well. Here's what the updated patch
implements:

* Single character Unicode strings in the Latin-1 range are shared
  (not only ASCII chars as in Martin's original patch).

* The ASCII and Latin-1 codecs make use of this optimization,
  providing a noticable speedup for single character strings. Most
  Unicode methods can use the optimization as well (by virtue
  of using PyUnicode_FromUnicode()).

* Some code cleanup was done (replacing memcpy with Py_UNICODE_COPY)

* The PyUnicode_Resize() can now also handle the case of resizing
  unicode_empty which previously resulted in an error.

* Modified the internal API _PyUnicode_Resize() and
  the public PyUnicode_Resize() API to handle references to
  shared objects correctly. The _PyUnicode_Resize() signature
  changed due to this.

* Callers of PyUnicode_FromUnicode() may now only modify the Unicode
  object contents of the returned object in case they called the API
  with NULL as content template.

Note that even though this patch passes the regression tests, there
may still be subtle bugs in the sharing code.

Guido van Rossum 213c7a6aa5 Mondo changes to the iterator stuff, without changing how Python code
sees it (test_iter.py is unchanged).

- Added a tp_iternext slot, which calls the iterator's next() method;
  this is much faster for built-in iterators over built-in types
  such as lists and dicts, speeding up pybench's ForLoop with about
  25% compared to Python 2.1.  (Now there's a good argument for
  iterators. ;-)

- Renamed the built-in sequence iterator SeqIter, affecting the C API
  functions for it.  (This frees up the PyIter prefix for generic
  iterator operations.)

- Added PyIter_Check(obj), which checks that obj's type has a
  tp_iternext slot and that the proper feature flag is set.

- Added PyIter_Next(obj) which calls the tp_iternext slot.  It has a
  somewhat complex return condition due to the need for speed: when it
  returns NULL, it may not have set an exception condition, meaning
  the iterator is exhausted; when the exception StopIteration is set
  (or a derived exception class), it means the same thing; any other
  exception means some other error occurred.

Guido van Rossum 05311481d4 Adding iterobject.[ch], which were accidentally not added. Sorry\! 2001-04-20 21:06:46 +00:00
Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises:
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)

Fred Drake 6a1c87ddf9 Add the necessary field for weak reference support to the function and
method types.
2001-03-23 04:17:58 +00:00
Ka-Ping Yee b5c5132d1a Add sys.excepthook.
Update docstring and library reference section on 'sys' module.
New API PyErr_Display, just for displaying errors, called by excepthook.
Uncaught exceptions now call sys.excepthook; if that fails, we fall back
    to calling PyErr_Display directly.
Also comes with sys.__excepthook__ and sys.__displayhook__.
2001-03-23 02:46:52 +00:00
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).

Jeremy Hylton 2e2cded1b5 Set the line number correctly for a nested function with an exec or
import *.  Mark the offending stmt rather than the function def line.
2001-03-22 03:57:58 +00:00
Jeremy Hylton bc32024769 Extend support for from __future__ import nested_scopes
If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.

If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.

XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported.  What's the point?

To support these changes, many function variants have been added to
pythonrun.c.  All the variants names end with Flags and they take an
extra PyCompilerFlags * argument.  It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.
2001-03-22 02:47:58 +00:00
Jeremy Hylton 061d106a0f If a code object is compiled with nested scopes, define the CO_NESTED flag.
Add PyEval_GetNestedScopes() which returns a non-zero value if the
code for the current interpreter frame has CO_NESTED defined.
2001-03-22 02:32:48 +00:00
Guido van Rossum 823649d544 Move the code implementing isinstance() and issubclass() to new C

Guido van Rossum b845cb0946 Bump version to 2.1b2. 2001-03-20 19:57:10 +00:00
Jeremy Hylton 30c9f3991c Variety of small INC/DECREF patches that fix reported memory leaks
with free variables.  Thanks to Martin v. Loewis for finding two of
the problems.  This fixes SF buf 405583.

There is also a C API change: PyFrame_New() is reverting to its
pre-2.1 signature.  The change introduced by nested scopes was a
mistake.  XXX Is this okay between beta releases?

cell_clear(), the GC helper, must decref its reference to break
cycles.

frame_dealloc() must dealloc all cell vars and free vars in addition
to locals.

eval_code2() setup code must INCREF cells it copies out of the
closure.

The STORE_DEREF opcode implementation must DECREF the object it passes
to PyCell_Set().

Guido van Rossum f0ee4b20a9 RISCOS patch by dschwertberger 2001-03-02 06:10:17 +00:00
Jeremy Hylton 9f324e964e Useful future statement support for the interactive interpreter
(Also remove warning about module-level global decl, because we can't
distinguish from code passed to exec.)

Define PyCompilerFlags type contains a single element,
cf_nested_scopes, that is true if a nested scopes future statement has
been entered at the interactive prompt.

New API functions:
    PyNode_CompileFlags()
    PyRun_InteractiveOneFlags()
    -- same as their non Flags counterparts except that the take an
       optional PyCompilerFlags pointer

compile.c: In jcompile() use PyCompilerFlags argument.  If
    cf_nested_scopes is true, compile code with nested scopes.  If it
    is false, but the code has a valid future nested scopes statement,
    set it to true.

pythonrun.c: Create a new PyCompilerFlags object in
    PyRun_InteractiveLoop() and thread it through to
    PyRun_InteractiveOneFlags().

Jeremy Hylton 39e2f3f824 Presumed correct compiler pass for future statements
XXX still need to integrate into symtable API

compile.h: Remove ff_n_simple_stmt; obsolete.

           Add ff_found_docstring used internally to skip one and only
           one string at the beginning of a module.

compile.c: Add check for from __future__ imports to far into the file.

 	   In symtable_global() check for -1 returned from
	   symtable_lookup(), which signifies name not defined.

	   Add missing DECERF in symtable_add_def.

           Free c->c_future.

future.c:  Add special handling for multiple statements joined on a
	   single line using one or more semicolons; this form can
           include an illegal future statement that would otherwise be
           hard to detect.

	   Add support for detecting and skipping doc strings.

2001-02-27 04:45:05 +00:00
Jeremy Hylton 29906eef3a Preliminary support for future nested scopes
compile.h: #define NESTED_SCOPES_DEFAULT 0 for Python 2.1
           __future__ feature name: "nested_scopes"

symtable.h: Add st_nested_scopes slot.  Define flags to track exec and
    import star.

Lib/test/test_scope.py: requires nested scopes

compile.c: Fiddle with error messages.

    Reverse the sense of ste_optimized flag on
    PySymtableEntryObjects.  If it is true, there is an optimization
    conflict.

    Modify get_ref_type to respect st_nested_scopes flags.

    Refactor symtable_load_symbols() into several smaller functions,
    which use struct symbol_info to share variables.  In new function
    symtable_update_flags(), raise an error or warning for import * or
    bare exec that conflicts with nested scopes.  Also, modify handle
    for free variables to respect st_nested_scopes flag.

    In symtable_init() assign st_nested_scopes flag to
    NESTED_SCOPES_DEFAULT (defined in compile.h).

    Add preliminary and often incorrect implementation of
    symtable_check_future().

    Add symtable_lookup() helper for future use.

2001-02-26 18:56:37 +00:00
Barry Warsaw a903ad9855 _Py_ReleaseInternedStrings(): Private API function to decref and
release the interned string dictionary.  This is useful for memory
use debugging because it eliminates a huge source of noise from the
reports.  Only defined when INTERN_STRINGS is defined.
2001-02-23 16:40:48 +00:00
Jeremy Hylton cb17ae8b19 Relax the rules for using 'from ... import *' and exec in the presence
of nested functions.  Either is allowed in a function if it contains
no defs or lambdas or the defs and lambdas it contains have no free
variables.  If a function is itself nested and has free variables,
either is illegal.

Revise the symtable to use a PySymtableEntryObject, which holds all
the revelent information for a scope, rather than using a bunch of
st_cur_XXX pointers in the symtable struct.  The changes simplify the
internal management of the current symtable scope and of the stack.

Added new C source file: Python/symtable.c.  (Does the Windows build
process need to be updated?)

As part of these changes, the initial _symtable module interface
introduced in 2.1a2 is replaced.  A dictionary of
PySymtableEntryObjects are returned.

Jeremy Hylton 5acc0c0cfc Fix symbol table pass to generation SyntaxError exceptions that
include the filename and line number.
2001-02-02 20:01:10 +00:00
Jeremy Hylton 4b38da664c Move a bunch of definitions that were internal to compile.c to
symtable.h, so that they can be used by external module.

Improve error handling in symtable_enter_scope(), which return an
error code that went unchecked by most callers. XXX The error handling
in symtable code is sloppy in general.

Modify symtable to record the line number that begins each scope.
This can help to identify which code block is being referred to when
multiple blocks are bound to the same name.

Add st_scopes dict that is used to preserve scope info when
PyNode_CompileSymtable() is called.  Otherwise, this information is
tossed as soon as it is no longer needed.

Add Py_SymtableString() to pythonrun; analogous to Py_CompileString().
2001-02-02 18:19:15 +00:00
Fred Drake 033f31270c Use a type flag to determine the applicability of the tp_weaklistoffset

2001-02-01 22:48:12 +00:00
Jeremy Hylton 483638c9a8 Undo recent change that banned using import to bind a global, as per
discussion on python-dev.  'from mod import *' is still banned except
at the module level.

Fix value for special NOOPT entry in symtable.  Initialze to 0 instead
of None, so that later uses of PyInt_AS_LONG() are valid.  (Bug
reported by Donn Cave.)

replace local REPR macros with PyObject_REPR in object.h

Fred Drake 41deb1efc2 PEP 205, Weak References -- initial checkin. 2001-02-01 05:27:45 +00:00
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.
2001-01-29 22:51:52 +00:00
Fred Drake 05473edbe5 Added prototype for PyInstance_NewRaw(). 2001-01-28 03:52:08 +00:00
Tim Peters d9b9ac855c It's unclear whether PyMarshal_XXX() are part of the public or private API.
They're named as if public, so I did a Bad Thing by changing
PyMarshal_ReadObjectFromFile() to suck up the remainder of the file in one
gulp:  anyone who counted on that leaving the file pointer merely at the
end of the next object would be screwed.  So restored
PyMarshal_ReadObjectFromFile() to its earlier state, renamed the new greedy
code to PyMarshal_ReadLastObjectFromFile(), and changed Python internals to
call the latter instead.

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.

Guido van Rossum c219d55bd0 Rich comparisons: ensure that LT == Py_LT, etc. 2001-01-17 15:21:09 +00:00
Guido van Rossum 5f284ce68e Introduction to rich comparisons:
- Removed the nb_add slot from the PyNumberMethods struct.

- Renamed Py_TPFLAGS_NEWSTYLENUMBER to Py_TPFLAGS_CHECKTYPES.

- Added typedef richcmpfunc.

- Added tp_richcompare slot to PyTypeObject (replacing spare tp_xxx7).

- Added APIs PyObject_RichCompare() and PyObject_RichCompareBool().

- Added rich comparison operators Py_LT through Py_GE.

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.

Thomas Wouters 2cffc7d420 Move our own getopt() implementation to _PyOS_GetOpt(), and use it
regardless of whether the system getopt() does what we want. This avoids the
hassle with prototypes and externs, and the check to see if the system
getopt() does what we want. Prefix optind, optarg and opterr with _PyOS_ to
avoid name clashes. Add new include file to define the right symbols. Fix
Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on
Python to provide it.

Marc-André Lemburg 77317ca7dc Added Py_FPROTO macro which was available in Python 1.5.x and below.

2000-09-23 03:24:27 +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.
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.

I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.

Changes include:

- There's a --with-pth configure option.

- Instead of _GNU_PTH, we test for HAVE_PTH.

- Better signal handling.

- (The config.h.in file is regenerated in a slightly different order.)

Tim Peters 4826a894c5 Close SF bug 110826: a complaint about the way Python #define'd NULL.
It's hard to sort out what the bug was, exactly.  So, Big Hammer:

1. Python shouldn't be in the business of #define'ing NULL, period.
2. Users of the Python C API shouldn't be in the business of not including
   Python.h, period.

Hence:

1. Removed all #define's of NULL in Python source code (pyport.h and
   object.h).
2. Since we're *relying* on stdio.h defining NULL, put an #error in
   Python.h after its #include of stdio.h if NULL isn't defined then.

Guido van Rossum 0df002c45b Add three new APIs: PyRun_AnyFileEx(), PyRun_SimpleFileEx(),
PyRun_FileEx().  These are the same as their non-Ex counterparts but
have an extra argument, a flag telling them to close the file when
done.

Then this is used by Py_Main() and execfile() to close the file after
it is parsed but before it is executed.

Adding APIs seems strange given the feature freeze but it's the only
way I see to close the bug report without incompatible changes.

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.

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.)

Start by moving a pointy-haired ones from their previous locations to the

(The gethostname() one, for instance, breaks on several systems, because
some define it as (char *, size_t) and some as (char *, int).)

I purposely decided not to include the summary of used #defines like Tim did
in the first section of pyport.h. In my opinion, the number of #defines
likedly to be used by this section would make such an overview unwieldy. I
would suggest documenting the non-obvious ones, though.

just casts VALUE from type WIDE to type NARROW, but assert-fails if

to expand to the correct thing based on RETSIGTYPE.  However,
only void is ANSI!  Do we still have platforms that return int?
The Unix config mess appears to #define RETSIGTYPE by magic
without being asked to, so I assume it's "a problem" across
Unices still.

Fred Drake 85f363990c Create two new exceptions: IndentationError and TabError. These are
used for indentation related errors.  This patch includes Ping's
improvements for indentation-related error messages.

Closes SourceForge patches #100734 and #100856.

Tim Peters 7d3a511a40 Cray J90 fixes for long ints.
This was a convenient excuse to create the pyport.h file recently
discussed!
Please use new Py_ARITHMETIC_RIGHT_SHIFT when right-shifting a
signed int and you *need* sign-extension.  This is #define'd in
pyport.h, keying off new config symbol SIGNED_RIGHT_SHIFT_ZERO_FILLS.
If you're running on a platform that needs that symbol #define'd,
the std tests never would have worked for you (in particular,
at least test_long would have failed).
The autoconfig stuff got added to Python after my Unix days, so
I don't know how that works.  Would someone please look into doing
& testing an auto-config of the SIGNED_RIGHT_SHIFT_ZERO_FILLS
symbol?  It needs to be defined if & only if, e.g., (-1) >> 3 is
not -1.

Greg Stein a90b23c571 One of the new prototypes was missing the "void" args. 2000-07-08 00:46:19 +00:00
Tim Peters 9ace6bc7ef Got RID of redundant coercions in longobject.c (as spotted by Greg
Stein -- thanks!).  Incidentally removed all the Py_PROTO macros
from object.h, as they prevented my editor from magically finding
the definitions of the "coercion", "cmpfunc" and "reprfunc"
typedefs that were being redundantly applied in longobject.c.

Marc-André Lemburg fa1309fd72 Fix to use Py_UCS4 2000-07-07 17:45:37 +00:00
Tim Peters 9f688bf9d2 Some cleanup of longs in prepartion for Cray J90 fixes: got
rid of Py_PROTO, switched to ANSI function decls, and did some
minor fiddling.
2000-07-07 15:53:28 +00:00
Marc-André Lemburg 5a5c81a0e9 Added new API PyUnicode_FromEncodedObject() which supports decoding
objects including instance objects.

The old API PyUnicode_FromObject() is still available as shortcut.
2000-07-07 13:46:42 +00:00
Marc-André Lemburg 295b1bbca1 Defunct the _XOPEN_SOURCE define for now. Suggested by Fredrik
Lundh as response to bug reports on True64 and IRIX.
2000-07-07 11:24:49 +00:00
Marc-André Lemburg 43279100f4 Bill Tutt: Added Py_UCS4 typedef to hold UCS4 values (these need
at least 32 bits as opposed to Py_UNICODE which rely on having
16 bits).
2000-07-07 09:01:41 +00:00
Marc-André Lemburg 3d1a1d7f0c Added prototypes for the new codec APIs for strings. These APIs
match the ones in the Unicode implementation, but were extended
to be able to reuse the existing Unicode codecs for string
purposes too.

Conversion from string to Unicode and back are done using the
default encoding.
2000-07-06 11:25:40 +00:00
Marc-André Lemburg f03e74126e Modified the ISALPHA and ISALNUM macros to use the new lookup APIs
from unicodectype.c
2000-07-05 09:45:59 +00:00
Marc-André Lemburg 82249c8389 Added #defines to enable SUSv2 compatibility where available and
to switch on support for BSD and SysV on platforms which use glibc
such as Linux.

These #defines are documented in e.g. the file /usr/include/features.h
on Linux platforms and the SUSv2 docs.
2000-07-05 08:53:18 +00:00
Tim Peters 1f5871e834 Removed Py_PROTO and switched to ANSI C declarations in the dict
implementation.  This was really to test whether my new CVS+SSH
setup is more usable than the old one -- and turns out it is (for
whatever reason, it was impossible to do a commit before that
involved more than one directory).
2000-07-04 17:44:48 +00:00
Marc-André Lemburg a9c103bc09 Added new Py_UNICODE_ISALPHA() and Py_UNICODE_ISALNUM() macros
which are true for alphabetic and alphanumeric characters resp.

The macros are currently implemented using the existing is* tables
but will have to be updated to meet the Unicode standard definitions
(add tables for non-cased letters and letter modifiers).

Guido van Rossum 632ea6e353 Bump version to 2.0b1. 2000-06-29 22:29:24 +00:00
Fred Drake 13634cf7a4 This patch addresses two main issues: (1) There exist some non-fatal
errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"

(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))

As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.

These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.

Jeremy Hylton d08b4c4524 part 2 of Neil Schemenauer's GC patches:
This patch modifies the type structures of objects that
participate in GC.  The object's tp_basicsize is increased when
GC is enabled.  GC information is prefixed to the object to
maintain binary compatibility.  GC objects also define the
tp_flag Py_TPFLAGS_GC.

implementation.
2000-06-23 14:18:11 +00:00
Jeremy Hylton 94988067b9 Add new parser error code, E_OVERFLOW. This error is returned when
the number of children of a node exceeds the max possible value for
the short that is used to count them.  The Python runtime converts
this parser error into the SyntaxError "expression too long."
2000-06-20 19:10:44 +00:00

Greg Ward 9581144329 Typo fix in comment. 2000-05-28 20:29:48 +00:00
Barry Warsaw c094ac856f Now that standard exceptions are builtin, we don't need two phase init
or fini of the builtin module.

_PyBuiltin_Init_1 => _PyBuiltin_Init
_PyBuiltin_Init_2 removed
_PyBuiltin_Fini_1 removed
_PyBuiltin_Fini_2 removed

These functions are used to initialize the _exceptions module.

init_exceptions added
fini_exceptions added

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)
2000-05-03 23:44:39 +00:00
Guido van Rossum e326b1efe2 At last, this backward compatibility file bites the dust.
If you still haven't updated your extension since the Grand Renaming,
you don't deserve Python 1.6. :-)
2000-05-02 19:09:40 +00:00
Guido van Rossum b16d197d66 Marc-Andre Lemburg:

Guido van Rossum e92e610a9e Christian Tismer -- total rewrite on trashcan code.
Improvements:
- does no longer need any extra memory
- has no relationship to tstate
- works in debug mode
- can easily be modified for free threading (hi Greg:)

Side effects:
Trashcan does change the order of object destruction.
Prevending that would be quite an immense effort, as
my attempts have shown. This version works always
the same, with debug mode or not. The slightly
changed destruction order should therefore be no problem.

Algorithm:
While the old idea of delaying the destruction of some
obejcts at a certain recursion level was kept, we now
no longer aloocate an object to hold these objects.
The delayed objects are instead chained together
via their ob_type field. The type is encoded via
ob_refcnt. When it comes to the destruction of the
chain of waiting objects, the topmost object is popped
off the chain and revived with type and refcount 1,
then it gets a normal Py_DECREF.

I am confident that this solution is near optimum
for minimizing side effects and code bloat.

Guido van Rossum 004d64f362 Marc-Andre Lemburg:
Changed PyUnicode_Splitlines() maxsplit argument to keepends.
The maxsplit functionality was replaced by the keepends
functionality which allows keeping the line end markers together
with the string.

Guido van Rossum 52c2359a59 Marc-Andre Lemburg: New exported API PyUnicode_Resize(). 2000-04-10 13:41:41 +00:00
Guido van Rossum 08df3ac066 Bump version to 1.6a2 -- to be released one of these days. 2000-04-06 15:01:30 +00:00
Guido van Rossum 9e896b37c7 Marc-Andre's third try at this bulk patch seems to work (except that
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent).  Checkin messages:


New Unicode support for int(), float(), complex() and long().

- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
  Unicode to a decimal char* string (used in the above new
  APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above

Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
  are masked, all other errors such as ValueError during
  Unicode coercion are passed through (note that PyUnicode_Compare
  does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
  masked and 0 returned; all other errors are passed through

Better testing support for the standard codecs.

Misc minor enhancements, such as an alias dbcs for the mbcs codec.

Changes:
- PyLong_FromString() now applies the same error checks as
  does PyInt_FromString(): trailing garbage is reported
  as error and not longer silently ignored. The only characters
  which may be trailing the digits are 'L' and 'l' -- these
  are still silently ignored.
- string.ato?() now directly interface to int(), long() and
  float(). The error strings are now a little different, but
  the type still remains the same. These functions are now
  ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
  in the input string; PyNumber_Long() already did this (and
  still does)

Followed by:

Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).

I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).
