[tarantool-patches] Re: [PATCH v1 3/4] box: introduce box_space_id_by_name

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

Hello. Thanks for the fixes!

The schema_find_id is still in C++ since it has tuple_field_u32_xc.
XC means exception. I removed it and slightly refactored other code.
The commit is force pushed and LGTM.
