[patches] [security 3/3] security: Refactor system space access checks
Ilya Markov
imarkov at tarantool.org
Tue Mar 27 15:26:52 MSK 2018
From: imarkov <imarkov at tarantool.org>
Processes of creating, dropping objects, granting contain work with
system spaces which so far must be available only to admin or user who has
write access to universe.
This patch removes the need of special accesses to universe.
Introduce virtual access_check function in space object and
separate its implementation for user spaces and system ones.
Move checks on write to system spaces to on_replace triggers.
Follow-up #945
Closes #3250
