Schorr <ajschorr@alumni.princeton.edu> + + * vtysh_main.c: (usage) Add new -d and -E options. And note that + -c can be used multiple times, possibly with embedded linefeeds. + (longopts) Add new -d and -E options. + (main) Add new -d and -E options, and create a linked list to + support multiple -c options. Do not call vtysh_connect_all until + after vtysh_read_config(config_default) and vtysh_auth have + succeeded. This prevents the vtysh.conf file from configuring + any daemons, and it ensures that authentication has been passed + before we send any commands to any daemons. Call vtysh_connect_all + with any daemon name supplied with -d. If it is unable to connect + to any daemons, issue an error message and exit immediately. + When used in -c mode, call vtysh_execute("enable") before + executing the commands in order to match interactive behavior. + And detect embedded linefeed chars in -c commands and break them up + appropriately. + * vtysh.h: (vtysh_connect_all) Fix proto to reflect new + daemon_name argument, and that it now returns an integer -- the + number of daemons to which we were able to connect. + * vtysh.c: (vtysh_connect_all) Add a new daemon_name argument. + If supplied, connect only to that daemon. And return + the number of daemons to which we were able to connect. + (vtysh_prompt): Performance enhancement -- make struct utsname + static so we call uname to get the hostname only once. + 2006-05-24 Paul Jakma <paul.jakma@sun.com> * vtysh.c: (general) Add 'show memory' command. diff --git a/vtysh/vtysh.c b/vtysh/vtysh.c index 110c361a..9b7d300f 100644 --- a/vtysh/vtysh.c +++ b/vtysh/vtysh.c @@ -2119,18 +2119,28 @@ vtysh_connect (struct vtysh_client *vclient) return 0; } -void -vtysh_connect_all(void) +int +vtysh_connect_all(const char *daemon_name) { u_int i; + int rc = 0; + int matches = 0; for (i = 0; i < VTYSH_INDEX_MAX; i++) { - vtysh_connect(&vtysh_client[i]); - /* We need direct access to ripd in vtysh_exit_ripd_only. */ - if (vtysh_client[i].flag == VTYSH_RIPD) - ripd_client = &vtysh_client[i]; + if (!daemon_name || !strcmp(daemon_name, vtysh_client[i].name)) + { + matches++; + if (vtysh_connect(&vtysh_client[i]) == 0) + rc++; + /* We need direct access to ripd in vtysh_exit_ripd_only. */ + if (vtysh_client[i].flag == VTYSH_RIPD) + ripd_client = &vtysh_client[i]; + } } + if (!matches) + fprintf(stderr, "Error: no daemons match name %s!\n", daemon_name); + return rc; } /* To disable readline's filename completion. */ @@ -2155,7 +2165,7 @@ vtysh_readline_init (void) char * vtysh_prompt (void) { - struct utsname names; + static struct utsname names; static char buf[100]; const char*hostname; extern struct host host; @@ -2164,7 +2174,8 @@ vtysh_prompt (void) if (!hostname) { - uname (&names); + if (!names.nodename[0]) + uname (&names); hostname = names.nodename; } diff --git a/vtysh/vtysh.h b/vtysh/vtysh.h index d619c294..dd2bcbd0 100644 --- a/vtysh/vtysh.h +++ b/vtysh/vtysh.h @@ -38,7 +38,7 @@ void vtysh_init_vty (void); void vtysh_init_cmd (void); -void vtysh_connect_all (void); +extern int vtysh_connect_all (const char *optional_daemon_name); void vtysh_readline_init (void); void vtysh_user_init (void); diff --git a/vtysh/vtysh_main.c b/vtysh/vtysh_main.c index 7f8e0592..134bcf73 100644 --- a/vtysh/vtysh_main.c +++ b/vtysh/vtysh_main.c @@ -32,6 +32,7 @@ #include <lib/version.h> #include "getopt.h" #include "command.h" +#include "memory.h" #include "vtysh/vtysh.h" #include "vtysh/vtysh_user.h" @@ -132,10 +133,15 @@ usage (int status) fprintf (stderr, "Try `%s --help' for more information.\n", progname); else printf ("Usage : %s [OPTION...]\n\n" \ - "Integrated shell for Quagga routing software suite. \n\n"\ + "Integrated shell for Quagga routing software suite. \n\n" \ "-b, --boot Execute boot startup configuration\n" \ - "-c, --command Execute argument as command\n "\ + "-c, --command Execute argument as command\n" \ + "-d, --daemon Connect only to the specified daemon\n" \ + "-E, --echo Echo prompt and command in -c mode\n" \ "-h, --help Display this help and exit\n\n" \ + "Note that multiple commands may be executed from the command\n" \ + "line by passing multiple -c args, or by embedding linefeed\n" \ + "characters in one or more of the commands.\n\n" \ "Report bugs to %s\n", progname, ZEBRA_BUG_ADDRESS); exit (status); @@ -148,6 +154,8 @@ struct option longopts[] = /* For compatibility with older zebra/quagga versions */ { "eval", required_argument, NULL, 'e'}, { "command", required_argument, NULL, 'c'}, + { "daemon", required_argument, NULL, 'd'}, + { "echo", no_argument, NULL, 'E'}, { "help", no_argument, NULL, 'h'}, { 0 } }; @@ -187,9 +195,14 @@ main (int argc, char **argv, char **env) { char *p; int opt; - int eval_flag = 0; int boot_flag = 0; - char *eval_line = NULL; + const char *daemon_name = NULL; + struct cmd_rec { + const char *line; + struct cmd_rec *next; + } *cmd = NULL; + struct cmd_rec *tail = NULL; + int echo_command = 0; /* Preserve name of myself. */ progname = ((p = strrchr (argv[0], '/')) ?
