Subject: [Tarantool-patches] [PATCH 10/13] txn: install proper diag errors on txn fail
Date: Fri, 11 Jun 2021 23:56:06 +0200
Message-ID: <82c470d34b0e86bbb643c83da236ad07462876d2.1623448465.git.v.shpilevoy@tarantool.org> (raw)
In-Reply-To: <cover.1623448465.git.v.shpilevoy@tarantool.org>

Previously all journal and txn errors were turned into ER_WAL_IO
error code. It led to loss of the real error, which sometimes was
absolutely not related to IO. For example, a timeout in the limbo
for a synchronous transaction.

The patch makes journal/txn errors turn into proper diags.

Part of #6027
