Subject: [PATCH v2 6/6] error: move XlogGapError to box/error.h
Date: Fri, 29 Jun 2018 19:48:33 +0300	[thread overview]
Message-ID: <c6932592681ff29d49880d026e82605a1bdf32da.1530287767.git.vdavydov.dev@gmail.com> (raw)

In-Reply-To: <cover.1530287767.git.vdavydov.dev@gmail.com>

All box exceptions belong to box/error.h. Let's move XlogGapError there
as well. This will facilitate conversion of recovery.cc to C when we
finally get to it. While we are at it, let's also move BuildXlogError
function declaration from diag.h to box/error.h, closer to its
definition.
