      Jeremy Hylton authored
      prevent binding for str from masking use of builtin str in nested
      function.
      
      (This is the only case I found in the standard library where a local
      shadows a global or builtin.  There may be others, but the regression
      test doesn't catch them.)

      PEP 227 implementation · a70642e8
      Jeremy Hylton authored
      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 implementation · 7f2a7c65
      Jeremy Hylton authored
      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.
