Subject: [Tarantool-patches] [PATCH v1 1/1] schema: remove assert on wrong insert into _priv
Date: Mon,  6 Sep 2021 11:11:45 +0300	[thread overview]
Message-ID: <38ac1b8d1ecae3352b8fe748def9e8a451239b9a.1630915850.git.imeevma@gmail.com> (raw)

Prior to this patch, an assertion was throwed if a tuple with an
incorrect id was inserted into the _priv system space. This bug
appeared only in the debug build.

Closes #6295
