From 29906eef3a56c43a4cd68a8706c75844b2384e59 Mon Sep 17 00:00:00 2001 From: Jeremy Hylton Date: Tue, 27 Feb 2001 04:23:34 +0000 Subject: Preliminary support for future nested scopes 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. --- Python/symtable.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Python/symtable.c') diff --git a/Python/symtable.c b/Python/symtable.c index 0d2e3243a1..3ec129dfc2 100644 --- a/Python/symtable.c +++ b/Python/symtable.c @@ -43,7 +43,7 @@ PySymtableEntry_New(struct symtable *st, char *name, int type, int lineno) goto fail; ste->ste_children = v; - ste->ste_optimized = 1; + ste->ste_optimized = 0; ste->ste_lineno = lineno; switch (type) { case funcdef: -- cgit v1.2.1
