diff Python/ceval.c @ 23194:0c8e762a677c 2.1

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Backport fixes for two nested scopes bugs. frameobject.c: make sure free and cell vars make it into locals, which makes eval work. bltinmodule.c & ceval.c: make sure a code object with free variables that is passed to exec or eval raises an exception. Also duplicate the current trunk test suite in the 2.1 branch, except for certain necessary changes: different warnings raised by 2.1, need for __future__.
