HAProxy - Load balancer
ec059c249e
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. |
