From: Vladislav Shpilevoy <v.shpilevoy@tarantool.org> To: tarantool-patches@freelists.org Cc: vdavydov.dev@gmail.com Subject: [PATCH v3 0/2] Outdate binary session on disconnect Date: Fri, 21 Dec 2018 19:48:39 +0300 [thread overview] Message-ID: <cover.1545410736.git.v.shpilevoy@tarantool.org> (raw) Once a connection is closed, a user can learn it using on_disconnect triggers. But session methods still work: session.fd() returns socket fd, session.sync() returns request sync, session.push() realy writes data to obuf and sends it to iproto thread. The goal of this patchset is to help user detect session disconnect even without setting on_disconnect triggers. Patchset makes a session, whose socket is closed, rotten. It returns an error on push, -1 on fd, 0 on sync. This is reached via moving struct session_vtab from a global array to struct session and changing the vtab on disconnect. V1: https://www.freelists.org/post/tarantool-patches/PATCH-04-Outdate-disconnected-session V2: https://www.freelists.org/post/tarantool-patches/PATCH-v2-04-Outdate-binary-session-on-disconnect Changes in v2: - Store vtab in struct session, remove session_vtab_registry; - Do not change session type on disconnect. Only vtab. Changes in v3: - Keep session_vtab_registry.
