* The addition of new parameters to functions in the Python/C API requiresFred Drake2001-01-251-2/+5
| | | | that PYTHON_API_VERSION be incremented.
* PEP 227 implementationJeremy Hylton2001-01-254-7/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* PEP 227 implementationJeremy Hylton2001-01-252-0/+29
| | | | | | A cell contains a reference to a single PyObject. It could be implemented as a mutable, one-element sequence, but the separate type has less overhead.

* Introduction to rich comparisons:Guido van Rossum2001-01-171-12/+22
| | | | | | | | | | | | | | - 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.
* Bump version to 2.1a1. (To be released Friday.)Guido van Rossum2001-01-171-4/+4

* Committing PEP 232, function attribute feature, approved by Guido.Barry Warsaw2001-01-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add declarations for standard warning category classes (PyExc_WarningGuido van Rossum2000-12-151-0/+10
| | | | etc.) and the PyErr_Warn() function.
* Move our own getopt() implementation to _PyOS_GetOpt(), and use itThomas Wouters2000-11-031-0/+17
| | | | | | | | | 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.

* Added Py_FPROTO macro which was available in Python 1.5.x and below.Marc-André Lemburg2000-10-051-0/+3
| | | | | | | This should not be used for new code, but will probably make porting old extensions to 2.0 a lot easier. Also see Bug #116011.
* Move LONG_BIT from intobject.c to pyport.h. #error if it's already beenTim Peters2000-10-051-0/+13
| | | | | | #define'd to an unreasonable value (several recent gcc systems have misdefined it, causing bogus overflows in integer multiplication). Nuke CHAR_BIT entirely.
* Rationalize use of limits.h, moving the inclusion to Python.h.Fred Drake2000-09-263-7/+36
| | | | | | | | Add definitions of INT_MAX and LONG_MAX to pyport.h. Remove includes of limits.h and conditional definitions of INT_MAX and LONG_MAX elsewhere. This closes SourceForge patch #101659 and bug #115323.
* It's.....Guido van Rossum2000-09-261-3/+3
| | | | | | | Python 2.0b2! (Note: Jeremy will finish the release on Sept. 26; I have to go on an unexpected business trip.)
* Andrew Kuchling <akuchlin@mems-exchange.org>:Fred Drake2000-09-231-0/+4
| | | | | | | Add three new convenience functions to the PyModule_*() family: PyModule_AddObject(), PyModule_AddIntConstant(), PyModule_AddStringConstant(). This closes SourceForge patch #101233.
* Derived from Martin's SF patch 110609: support unbounded ints in ↵Tim Peters2000-09-211-0/+2
| | | | | | | | | | | | | | | | %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.
* This patch adds a new Python C API called PyString_AsStringAndSize()Marc-André Lemburg2000-09-191-0/+15
| | | | | | | | | | | | | 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.
* Make better use of GNU Pth -- patch by Andy Dustman.Guido van Rossum2000-09-191-1/+1
| | | | | | | | | | | | | | | 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.)

* Close SF bug 110826: a complaint about the way Python #define'd NULL.Tim Peters2000-09-103-11/+4
| | | | | | | | | | | | | | | 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.
* A #define didn't start in column 1. Closes SF bug 113888.Tim Peters2000-09-081-1/+1

* Add three new APIs: PyRun_AnyFileEx(), PyRun_SimpleFileEx(),Guido van Rossum2000-08-271-0/+4
| | | | | | | | | | | | | | 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. [ Bug #110616 ] source file stays open after parsing is done (PR#209)
