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.

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.

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.

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().

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

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.

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.

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.

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.

- 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.
