From: Florian Forster Date: Wed, 27 Aug 2008 15:41:46 +0000 (+0200) Subject: src/utils_cmd_putnotif.[ch]: Change parsing to allow quoted strings. X-Git-Tag: collectd-4.5.0~10 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=5f3edac68db5716fbf106392b99b6abe33d90d5f;p=collectd.git src/utils_cmd_putnotif.[ch]: Change parsing to allow quoted strings. This completes all the commands, now quoted strings should be accepted anywhere. --- diff --git a/src/exec.c b/src/exec.c index 88026b66..711ec996 100644 --- a/src/exec.c +++ b/src/exec.c @@ -492,11 +492,8 @@ static int parse_line (char *buffer) /* {{{ */ { if (strncasecmp ("PUTVAL", buffer, strlen ("PUTVAL")) == 0) return (handle_putval (stdout, buffer)); -#if !COLLECT_DEBUG -#error "TODO: PUTNOTIF" - else if (strcasecmp (fields[1], "putnotif") == 0) - return (handle_putnotif (stdout, fields + 1, fields_num)); -#endif + else if (strncasecmp ("PUTNOTIF", buffer, strlen ("PUTNOTIF")) == 0) + return (handle_putnotif (stdout, buffer)); else { /* For backwards compatibility */ diff --git a/src/unixsock.c b/src/unixsock.c index 02f329f6..8f06046c 100644 --- a/src/unixsock.c +++ b/src/unixsock.c @@ -251,7 +251,7 @@ static void *us_handle_client (void *arg) } else if (strcasecmp (fields[0], "putnotif") == 0) { - handle_putnotif (fhout, fields, fields_num); + handle_putnotif (fhout, buffer); } else if (strcasecmp (fields[0], "flush") == 0) { diff --git a/src/utils_cmd_putnotif.c b/src/utils_cmd_putnotif.c index eb7d60bc..5a9faff2 100644 --- a/src/utils_cmd_putnotif.c +++ b/src/utils_cmd_putnotif.c @@ -23,6 +23,8 @@ #include "common.h" #include "plugin.h" +#include "utils_parse_option.h" + #define print_to_socket(fh, ...) \ if (fprintf (fh, __VA_ARGS__) < 0) { \ char errbuf[1024]; \ @@ -31,7 +33,7 @@ return -1; \ } -static int parse_option_severity (notification_t *n, char *value) +static int set_option_severity (notification_t *n, const char *value) { if (strcasecmp (value, "Failure") == 0) n->severity = NOTIF_FAILURE; @@ -43,9 +45,9 @@ static int parse_option_severity (notification_t *n, char *value) return (-1); return (0); -} /* int parse_option_severity */ +} /* int set_option_severity */ -static int parse_option_time (notification_t *n, char *value) +static int set_option_time (notification_t *n, const char *value) { time_t tmp; @@ -56,25 +58,22 @@ static int parse_option_time (notification_t *n, char *value) n->time = tmp; return (0); -} /* int parse_option_time */ +} /* int set_option_time */ -static int parse_option (notification_t *n, char *buffer) +static int set_option (notification_t *n, const char *option, const char *value) { - char *option = buffer; - char *value; - - if ((n == NULL) || (option == NULL)) + if ((n == NULL) || (option == NULL) || (value == NULL)) return (-1); - value = strchr (option, '='); - if (value == NULL) - return (-1); - *value = '\0'; value++; + DEBUG ("utils_cmd_putnotif: set_option (option = %s, value = %s);", + option, value); if (strcasecmp ("severity", option) == 0) - return (parse_option_severity (n, value)); + return (set_option_severity (n, value)); else if (strcasecmp ("time", option) == 0) - return (parse_option_time (n, value)); + return (set_option_time (n, value)); + else if (strcasecmp ("message", option) == 0) + sstrncpy (n->message, value, sizeof (n->message)); else if (strcasecmp ("host", option) == 0) sstrncpy (n->host, value, sizeof (n->host)); else if (strcasecmp ("plugin", option) == 0) @@ -89,61 +88,55 @@ static int parse_option (notification_t *n, char *buffer) return (1); return (0); -} /* int parse_option */ +} /* int set_option */ -static int parse_message (notification_t *n, char **fields, int fields_num) +int handle_putnotif (FILE *fh, char *buffer) { + char *command; + notification_t n; int status; - /* Strip off the leading `message=' */ - fields[0] += strlen ("message="); - - status = strjoin (n->message, sizeof (n->message), fields, fields_num, " "); - if (status < 0) + if ((fh == NULL) || (buffer == NULL)) return (-1); - return (0); -} /* int parse_message */ + DEBUG ("utils_cmd_putnotif: handle_putnotif (fh = %p, buffer = %s);", + (void *) fh, buffer); -int handle_putnotif (FILE *fh, char **fields, int fields_num) -{ - notification_t n; - int status; - int i; + command = NULL; + status = parse_string (&buffer, &command); + if (status != 0) + { + print_to_socket (fh, "-1 Cannot parse command.\n"); + return (-1); + } + assert (command != NULL); - /* Required fields: `PUTNOTIF', severity, time, message */ - if (fields_num < 4) + if (strcasecmp ("PUTNOTIF", command) != 0) { - DEBUG ("cmd putnotif: Wrong number of fields: %i", fields_num); - print_to_socket (fh, "-1 Wrong number of fields: Got %i, " - "expected at least 4.\n", - fields_num); + print_to_socket (fh, "-1 Unexpected command: `%s'.\n", command); return (-1); } memset (&n, '\0', sizeof (n)); status = 0; - for (i = 1; i < fields_num; i++) + while (*buffer != 0) { - if (strncasecmp (fields[i], "message=", strlen ("message=")) == 0) + char *key; + char *value; + + status = parse_option (&buffer, &key, &value); + if (status != 0) { - status = parse_message (&n, fields + i, fields_num - i); - if (status != 0) - { - print_to_socket (fh, "-1 Error parsing the message.
