* When an inlined operation on two small ints causes overflow, don'tGuido van Rossum2001-08-231-32/+24
| | | | | raise the exception here -- call the generic function (which may convert the arguments to long and try again).
* Introduce OverflowWarning -- to be issued when short int operationsGuido van Rossum2001-08-231-0/+7
| | | | are overflowing and a long int operation is substituted.
* Fix SF bug [ #450245 ] Error in parsing future stmtsJeremy Hylton2001-08-201-3/+18
| | | | | | | | | Check return value from future_parse() in for loop for file_input to accomodate multiple future statements on separate lines. Add several comments explaining how the code works. Remove out-dated XXX comment.
* Fix SF bug #443600:Guido van Rossum2001-08-181-15/+46
| | | | | | | | Change to get/set/del slice operations so that if the object doesn't support slicing, *or* if either of the slice arguments is not an int or long, we construct a slice object and call the get/set/del item operation instead. This makes it possible to design classes that support slice arguments of non-integral types.
* Fix for bug [#452230] future division isn't propagated.Tim Peters2001-08-171-1/+8
| | | | | | | builtin_eval wasn't merging in the compiler flags from the current frame; I suppose we never noticed this before because future division is the first future-feature that can affect expressions (nested_scopes and generators had only statement-level effects).
* A fiddled version of the rest of Michael Hudson's SF patchTim Peters2001-08-171-8/+26
| | | | | #449043 supporting __future__ in simulated shells which implements PEP 264.
* ceval, PyEval_MergeCompilerFlags: wasn't merging in theTim Peters2001-08-171-6/+3
| | | | | | | | | | | | | | CO_FUTURE_DIVISION flag. Redid this to use Jeremy's PyCF_MASK #define instead, so we dont have to remember to fiddle individual feature names here again. pythonrun.h: Also #define a PyCF_MASK_OBSOLETE mask. This isn't used yet, but will be as part of the PEP 264 implementation (compile() mustn't raise an error just because old code uses a flag name that's become obsolete; a warning may be appropriate, but not an error; so compile() has to know about obsolete flags too, but nobody is going to remember to update compile() with individual obsolete flag names across releases either -- i.e., this is the flip side of PyEval_MergeCompilerFlags's oversight).
* Patch #445762: Support --disable-unicodeMartin v. Löwis2001-08-177-14/+80
| | | | | | | | - Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled - check for Py_USING_UNICODE in all places that use Unicode functions - disables unicode literals, and the builtin functions - add the types.StringTypes list - remove Unicode literals from most tests.
* Patch #427190: Implement and use METH_NOARGS and METH_O.Martin v. Löwis2001-08-163-168/+138

* Oops. Two fixes for SF bug #422004 are not needed. :-)Guido van Rossum2001-08-161-1/+0

* Bunchathings:Guido van Rossum2001-08-161-5/+6
| | | | | | | | | | | - initsigs(): Ignore SIGXFZ so writing files beyond the file system size limit won't kill us. - Py_Initialize(): call _Py_ReadyTypes() instead of readying types here. - Py_Initialize(): call _PyImport_FixupExtension() for module "extensions". (SF bug #422004.)
* Fix SF bug [ #450909 ] __future__.division fails at promptJeremy Hylton2001-08-141-2/+6
| | | | | | When code is compiled and compiler flags are passed in, be sure to update cf_flags with any features defined by future statements in the compiled code.
* Fixed typo in comment leading up to _PyImport_FixupExtension().Barry Warsaw2001-08-131-1/+1
|
* Py_Initialize(): Apply patch by Jürgen Hermann to callBarry Warsaw2001-08-131-0/+1
| | | | | | | | _PyImport_FixupExtension() on the exceptions module. Now reload(exceptions) acts just like reload(sys) instead of raising an ImportError. This closes SF bug #422004.
* Remove much dead code from ceval.cJeremy Hylton2001-08-121-220/+18
| | | | | | | | | | | | | | The descr changes moved the dispatch for calling objects from call_object() in ceval.c to PyObject_Call() in abstract.c. call_object() and the many functions it used in ceval.c were no longer used, but were not removed. Rename meth_call() as PyCFunction_Call() so that it can be called by the CALL_FUNCTION opcode in ceval.c. Also, fix error message that referred to PyEval_EvalCodeEx() by its old name eval_code2(). (I'll probably refer to it by its old name, too.)
* SF Patch [ 429024 ] deal with some unary ops at compile timeJeremy Hylton2001-08-121-3/+66
| | | | | | | | | | | | | Revised version of Fred's patch, including support for ~ operator. If the unary +, -, or ~ operator is applied to a constant, don't generate a UNARY_xxx opcode. Just store the approriate value as a constant. If the value is negative, extend the string containing the constant and insert a negative in the 0th position. For ~, compute the inverse of int and longs and use them directly, but be prepared to generate code for all other possibilities (invalid numbers, floats, complex).
* Patch by Jonathan Wight (slightly reformatted) to forestall loading theJack Jansen2001-08-111-3/+7
| | | | | | | | same module twice, which apparently crashes Python. I could not test the error condition, but in normal life it seems to have no adverse effects. Also removed an unsued variable, and corrected 2 glaring errors (missing 'case' in front of a label).
* Remove st_nested_scopes from struct symtable,Jeremy Hylton2001-08-111-130/+46
| | | | | | | because nested scopes are always enabled. (Accidentally checked in one small change along this path yesterday, wreaking havoc in the Windows build.)
* st_nested_scopes was uninitialized trash. Jeremy should fix in a betterTim Peters2001-08-111-0/+6
| | | | way; see code comments.
* Refactor future feature handlingJeremy Hylton2001-08-104-52/+17
| | | | | | | | | | | Replace uses of PyCF_xxx with CO_xxx. Replace individual feature slots in PyFutureFeatures with single bitmask ff_features. When flags must be transfered among the three parts of the interpreter that care about them -- the pythonrun layer, the compiler, and the future feature parser -- can simply or (|) the definitions.

* Split macglue.c into two: a new mactoolboxglue.c (in ./Python)Jack Jansen2001-08-081-0/+430
| | | | | | | | | | | | with functionality needed for both unix-Python and MacPython and a new smaller ./Mac/Python/macglue.c which contains MacPython stuff only. pymactoolbox.h has moved to ./Include from ./Mac/Include and now also contains the relevant stuff from macglue.h. The net effect of this is that the ./Mac subdirectory is not needed anymore for building the unix-Python core on MacOSX (it is needed for building the extension modules).
* Put conditional S_IFMT definition into pyport.h.Martin v. Löwis2001-08-081-5/+0

* Repair the Windows build (S_ISDIR() macro doesn't exist).Tim Peters2001-08-081-1/+1
| | | | | Somebody else should feel free to repair this a different way; see Python- Dev for discussion.

* Implement PEP 238 in its (almost) full glory.Guido van Rossum2001-08-084-196/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | This introduces: - A new operator // that means floor division (the kind of division where 1/2 is 0). - The "future division" statement ("from __future__ import division) which changes the meaning of the / operator to implement "true division" (where 1/2 is 0.5). - New overloadable operators __truediv__ and __floordiv__. - New slots in the PyNumberMethods struct for true and floor division, new abstract APIs for them, new opcodes, and so on. I emphasize that without the future division statement, the semantics of / will remain unchanged until Python 3.0. Not yet implemented are warnings (default off) when / is used with int or long arguments. This has been on display since 7/31 as SF patch #443474. Flames to /dev/null.
* - Rename PyType_InitDict() to PyType_Ready().Guido van Rossum2001-08-071-1/+4
| | | | | | - Add an explicit call to PyType_Ready(&PyList_Type) to pythonrun.c (just for the heck of it, really -- we should either explicitly ready all types, or none).
* Another bug fix for recent import * warning (caught by Thomas Wouters)Jeremy Hylton2001-08-061-3/+3
| | | | | Only return if symtable_warn() returns -1, indicating that the warning was turned into an error.

* This patch turns the Python API mismatch notice into a standardMarc-André Lemburg2001-07-312-5/+107
| | | | | | | | | | | | Python warning which can be catched by means of the Python warning framework. It also adds two new APIs which hopefully make it easier for Python to switch to buffer overflow safe [v]snprintf() APIs for error reporting et al. The two new APIs are PyOS_snprintf() and PyOS_vsnprintf() and work just like the standard ones in many C libs. On platforms which have snprintf(), the native APIs are used, on all other an emulation with snprintf() tries to do its best.
* Do for hasattr() what was done for getattr()Jeremy Hylton2001-07-301-0/+11
| | | | | Namely, an exception is raised if the second arg to hasattr() is not a string or Unicode.
* Fix for SF byg [ #420304 ] getattr function w/ defaultJeremy Hylton2001-07-301-0/+11
| | | | | | | Fix suggested by Michael Hudson: Raise TypeError if attribute name passed to getattr() is not a string or Unicode. There is some unfortunate duplication of code between builtin_getattr() and PyObject_GetAttr(), but it appears to be unavoidable.
* Add _PyUnicode_AsDefaultEncodedString to unicodeobject.h.Jeremy Hylton2001-07-301-5/+0
| | | | | | | And remove all the extern decls in the middle of .c files. Apparently, it was excluded from the header file because it is intended for internal use by the interpreter. It's still intended for internal use and documented as such in the header file.
* Fix for SF bug [ #443866 ] Evaluating func_code causing core dumpJeremy Hylton2001-07-301-1/+7
| | | | If the code object has free variables, raise TypeError.
