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.

This should match the situation in the 1.6b1 tree.

PySequence methods and functions, new tokens.

Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit arguments to opcodes instead of being forced to stick to the 16-bit limit. This is especially useful for machine-generated code, which can be too long for the SET_LINENO parameter to fit into 16 bits. This closes the implementation portion of SourceForge patch #100893.

This adds the two new opcodes to support this feature: PRINT_ITEM_TO, PRINT_NEWLINE_TO.

name as n'. By doing some twists and turns, "as" is not a reserved word. There is a slight change in semantics for 'from module import name' (it will now honour the 'global' keyword) but only in cases that are explicitly undocumented.

did the same anyway. I'm not sure what to do with Tools/compiler/compiler/* -- that isn't part of distutils, is it ? Should it try to be compatible with old bytecode version ?

executive summary: Instead of typing 'apply(f, args, kwargs)' you can type 'f(*arg, **kwargs)'. Some file-by-file details follow. Grammar/Grammar: simplify varargslist, replacing '*' '*' with '**' add * & ** options to arglist Include/opcode.h & Lib/dis.py: define three new opcodes CALL_FUNCTION_VAR CALL_FUNCTION_KW CALL_FUNCTION_VAR_KW Python/ceval.c: extend TypeError "keyword parameter redefined" message to include the name of the offending keyword reindent CALL_FUNCTION using four spaces add handling of sequences and dictionaries using extend calls fix function import_from to use PyErr_Format

object.h: made sizes and refcnts signed ints. stringobject.h: make getstrsize() signed int. methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.

* Grammar: add exec statement; allow testlist in expr statement. * ceval.c, compile.c, opcode.h: support exec statement; avoid optimizing locals when it is used * fileobject.{c,h}: add getfilename() internal function.

* Makefile: change location of FORMS library. * posixmodule.c: turn #if 0 into #ifdef MSDOS (stuff in unistd.h or not) * Almost all .h files: added CPP magic to avoid duplicate inclusions and to support inclusion from C++.

(1) dictionaries/mappings now have attributes values() and items() as well as keys(); at the C level, use the new function mappinggetnext() to iterate over a dictionary. (2) "class C(): ..." is now illegal; you must write "class C: ...". (3) Class objects now know their own name (finally!); and minor improvements to the way how classes, functions and methods are represented as strings. (4) Added an "access" statement and semantics. (This is still experimental -- as long as you don't use the keyword 'access' nothing should be changed.)

lookup (opcode.h, ceval.[ch], compile.c, frameobject.[ch], pythonrun.c, import.c). The .pyc MAGIC number is changed again. Added get_menu_text to flmodule.

* Stubs for faster implementation of local variables (not yet finished) * Added function name to code object. Print it for code and function objects. THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version number has changed accordingly) * Print address of self for built-in methods * New internal functions getattro and setattro (getattr/setattr with string object arg) * Replaced "dictobject" with more powerful "mappingobject" * New per-type functio tp_hash to implement arbitrary object hashing, and hashobject() to interface to it * Added built-in functions hash(v) and hasattr(v, 'name') * classobject: made some functions static that accidentally weren't; added __hash__ special instance method to implement hash() * Added proper comparison for built-in methods and functions
