From 20636d956dd36c1f14152569a4d44a50eea9083d Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Sun, 24 Mar 2013 09:54:10 +0000 Subject: Add a command queue to standardize and simplify commands that call other commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client. --- cmd-has-session.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'cmd-has-session.c') diff --git a/cmd-has-session.c b/cmd-has-session.c index 8e77942a..28e3aea3 100644 --- a/cmd-has-session.c +++ b/cmd-has-session.c @@ -24,7 +24,7 @@ * Cause client to report an error and exit with 1 if session doesn't exist. */ -enum cmd_retval cmd_has_session_exec(struct cmd *, struct cmd_ctx *); +enum cmd_retval cmd_has_session_exec(struct cmd *, struct cmd_q *); const struct cmd_entry cmd_has_session_entry = { "has-session", "has", @@ -37,11 +37,11 @@ const struct cmd_entry cmd_has_session_entry = { }; enum cmd_retval -cmd_has_session_exec(struct cmd *self, struct cmd_ctx *ctx) +cmd_has_session_exec(struct cmd *self, struct cmd_q *cmdq) { struct args *args = self->args; - if (cmd_find_session(ctx, args_get(args, 't'), 0) == NULL) + if (cmd_find_session(cmdq, args_get(args, 't'), 0) == NULL) return (CMD_RETURN_ERROR); return (CMD_RETURN_NORMAL); -- cgit
