From: Kirill Shcherbatov <kshcherbatov@tarantool.org> To: tarantool-patches@freelists.org, vdavydov.dev@gmail.com Cc: Kirill Shcherbatov <kshcherbatov@tarantool.org> Subject: [PATCH v2 8/9] box: implement lua_port dump to region and to Lua Date: Thu, 6 Jun 2019 15:04:04 +0300 [thread overview] Message-ID: <d9c0a52be75f032de99df2102b7f8299f27d80bb.1559822429.git.kshcherbatov@tarantool.org> (raw) In-Reply-To: <cover.1559822429.git.kshcherbatov@tarantool.org> Refactored port_lua class to reuse an existent machinery to dump info not only for obuf, but to region, that is also mpstream-compatible. We need this feature in scope of multikey indexes to work with keys produced with functional index extractor in memory. Also introduce a tiny method .dump_lua for port_lua. It is necessary to export registered on-board functions call endpoints. Class implementation is moved to a new file port_lua.c.
