When using the "reload" command over the master CLI, all connections to the master CLI were cut, this was unfortunate because it could have been used to implement a synchronous reload command. This patch implements an architecture to keep the connection alive after the reload. The master CLI is now equipped with a listener which uses a socketpair, the 2 FDs of this socketpair are stored in the mworker_proc of the master, which the master keeps via the environment variable. ipc_fd[1] is used as a listener for the master CLI. During the "reload" command, the CLI will send the FD of the current session over ipc_fd[0], then the reload is achieved, so the master won't handle the recv of the FD. Once reloaded, ipc_fd[1] receives the FD of the session, so the connection is preserved. Of course it is a new context, so everything like the "prompt mode" are lost. Only the FD which performs the reload is kept. |
