Gerald Dalley <dall...@deshaw.com> added the comment: Another use case: for distributed processing, it's handy to be able to pickle interactive functions and functions that are part of a script. The user can then remotely execute a broader set of functions than can be pickled by default. This is especially helpful for interactive exploration of data.
Pickling most types of functions is possible by serializing a function's bytecode, etc. and registering a handler with copy_reg. Unfortunately, this handler is ignored under some conditions (e.g. copy_reg is ignored when attempting to serialize top-level functions in a script) but the copy_reg handler does get used for lambdas and inner functions. This patch looks like it will allow FunctionType's pickle handler to be overridden in all cases. ---------- nosy: +dalleyg _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7689> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
