This was using 4 bytes for each such piece of info regardless of platform. This didn't really matter before (proof: no bug reports, and the debug-build obmalloc would have assert-failed if it was ever asked for a chunk of memory >= 2**32 bytes), since container indices were plain ints. But after the Py_ssize_t changes, it's at least theoretically possible to allocate a list or string whose guts exceed 2**32 bytes, and the PYMALLOC_DEBUG routines would fail then (having only 4 bytes to record the originally requested size). Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG build's extra debugging fields. This won't make any difference on 32-bit boxes, but will add 16 bytes to each allocation in a debug build on a 64-bit box. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

2007-06-13 15:07:49 -03:00
The next several functions are helpers for symtable_analyze(),
which determines whether a name is local, global, or free. In addition,
it determines which local variables are cell variables; they provide
bindings that are used for free variables in enclosed blocks.
There are also two kinds of global variables, implicit and explicit. An
explicit global is declared with the global statement. An implicit
global is a free variable for which the compiler has found no binding
in an enclosing function scope. The implicit global is either a global
or a builtin. Python's module and class blocks use the xxx_NAME opcodes
to handle these names to implement slightly odd semantics. In such a
block, the name is treated as global until it is assigned to; then it
is treated as a local.
The symbol table requires two passes to determine the scope of each name.
The first pass collects raw facts from the AST via the symtable_visit_*
functions: the name is a parameter here, the name is used but not defined
here, etc. The second pass analyzes these facts during a pass over the
PySTEntryObjects created during pass 1.
When a function is entered during the second pass, the parent passes
the set of all name bindings visible to its children. These bindings
are used to determine if non-local variables are free or implicit globals.
Names which are explicitly declared nonlocal must exist in this set of
visible names - if they do not, a syntax error is raised. After doing
the local analysis, it analyzes each of its child blocks using an
updated set of name bindings.
The children update the free variable set. If a local variable is added to
the free variable set by the child, the variable is marked as a cell. The
function object being defined must provide runtime storage for the variable
that may outlive the function's frame. Cell variables are removed from the
free set before the analyze function returns to its parent.
During analysis, the names are:
symbols: dict mapping from symbol names to flag values (including offset scope values)
scopes: dict mapping from symbol names to scope values (no offset)
local: set of all symbol names local to the current scope
bound: set of all symbol names local to a containing function scope
free: set of all symbol names referenced but not bound in child scopes
global: set of all symbol names explicitly declared as global
