* Excise DL_EXPORT from Include.Mark Hammond2002-08-121-7/+7
| | | | Thanks to Skip Montanaro and Kalle Svensson for the patches.
* SF patch # 580411, move frame macros from frameobject.h into ceval.cNeal Norwitz2002-07-141-20/+0
| | | | | remove unused macros use co alias instead of f->f_code in macros

* PyFrameObject: rename f_stackbottom to f_stacktop, since it points toTim Peters2001-06-231-2/+4
| | | | | | | | the next free valuestack slot, not to the base (in America, stacks push and pop at the top -- they mutate at the bottom in Australia <winK>). eval_frame(): assert that f_stacktop isn't NULL upon entry. frame_delloc(): avoid ordered pointer comparisons involving f_stacktop when f_stacktop is NULL.
* Merging the gen-branch into the main line, at Guido's direction. Yay!Tim Peters2001-06-181-0/+2
| | | | | Bugfix candidate in inspect.py: it was referencing "self" outside of a method.
* Variety of small INC/DECREF patches that fix reported memory leaksJeremy Hylton2001-03-131-2/+1
| | | | | | | | | | | | | | | | | | | | | 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().
* Remove f_closure slot of frameobject and use f_localsplus instead.Jeremy Hylton2001-01-291-1/+3
| | | | | | | | | | | | 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.
* PEP 227 implementationJeremy Hylton2001-01-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Access checks now work, at least for instance data (not for methodsGuido van Rossum1993-05-201-1/+2
| | | | | | | yet). The class is now passed to eval_code and stored in the current frame. It is also stored in instance method objects. An "unbound" instance method is now returned when a function is retrieved through "classname.funcname", which when called passes the class to eval_code.
