From 86bc39b65ad72ba8d92d6bc6780774b3c560df17 Mon Sep 17 00:00:00 2001 From: Michael Jumper Date: Thu, 15 Mar 2012 19:11:51 -0700 Subject: [PATCH] Use guacd_log_*() for all logging. Replace use of syslog. Only use fprintf() for usage information. --- guacd/src/daemon.c | 44 ++++++++++++++++++++++---------------------- 1 file changed, 22 insertions(+), 22 deletions(-) diff --git a/guacd/src/daemon.c b/guacd/src/daemon.c index 9a3de231..dd4ab8a3 100644 --- a/guacd/src/daemon.c +++ b/guacd/src/daemon.c @@ -82,7 +82,7 @@ void guacd_handle_connection(int fd) { if (select->argc != 1) { /* Log error */ - syslog(LOG_ERR, "Bad number of arguments to \"select\" (%i)", + guacd_log_error("Bad number of arguments to \"select\" (%i)", select->argc); /* Free resources */ @@ -90,7 +90,7 @@ void guacd_handle_connection(int fd) { return; } - syslog(LOG_INFO, "Protocol \"%s\" selected", select->argv[0]); + guacd_log_info("Protocol \"%s\" selected", select->argv[0]); /* Get plugin from protocol in select */ plugin = guac_client_plugin_open(select->argv[0]); @@ -154,16 +154,16 @@ void guacd_handle_connection(int fd) { } /* Start client threads */ - syslog(LOG_INFO, "Starting client"); + guacd_log_info("Starting client"); if (guacd_client_start(client)) - syslog(LOG_ERR, "Client finished abnormally"); + guacd_log_error("Client finished abnormally"); else - syslog(LOG_INFO, "Client finished normally"); + guacd_log_info("Client finished normally"); /* Clean up */ guac_client_free(client); if (guac_client_plugin_close(plugin)) - syslog(LOG_ERR, "Error closing client plugin"); + guacd_log_error("Error closing client plugin"); /* Close socket */ guac_socket_close(socket); @@ -229,7 +229,7 @@ int main(int argc, char* argv[]) { /* Get addresses for binding */ if ((retval = getaddrinfo(listen_address, listen_port, &hints, &addresses))) { - fprintf(stderr, "Error parsing given address or port: %s\n", + guacd_log_error("Error parsing given address or port: %s\n", gai_strerror(retval)); exit(EXIT_FAILURE); } @@ -237,13 +237,13 @@ int main(int argc, char* argv[]) { /* Get socket */ socket_fd = socket(AF_INET, SOCK_STREAM, 0); if (socket_fd < 0) { - fprintf(stderr, "Error opening socket: %s\n", strerror(errno)); + guacd_log_error("Error opening socket: %s\n", strerror(errno)); exit(EXIT_FAILURE); } /* Allow socket reuse */ if (setsockopt(socket_fd, SOL_SOCKET, SO_REUSEADDR, (void*) &opt_on, sizeof(opt_on))) { - fprintf(stderr, "Warning: Unable to set socket options for reuse: %s\n", strerror(errno)); + guacd_log_info("Unable to set socket options for reuse: %s\n", strerror(errno)); } /* Attempt binding of each address until success */ @@ -258,7 +258,7 @@ int main(int argc, char* argv[]) { bound_address, sizeof(bound_address), bound_port, sizeof(bound_port), NI_NUMERICHOST | NI_NUMERICSERV))) - fprintf(stderr, "Unable to resolve host: %s\n", + guacd_log_error("Unable to resolve host: %s\n", gai_strerror(retval)); /* Attempt to bind socket to address */ @@ -266,7 +266,7 @@ int main(int argc, char* argv[]) { current_address->ai_addr, current_address->ai_addrlen) == 0) { - fprintf(stderr, "Successfully bound socket to " + guacd_log_error("Successfully bound socket to " "host %s, port %s\n", bound_address, bound_port); /* Done if successful bind */ @@ -276,7 +276,7 @@ int main(int argc, char* argv[]) { /* Otherwise log error */ else - fprintf(stderr, "Error binding socket to " + guacd_log_error("Error binding socket to " "host %s, port %s: %s\n", bound_address, bound_port, strerror(errno)); @@ -286,7 +286,7 @@ int main(int argc, char* argv[]) { /* If unable to bind to anything, fail */ if (current_address == NULL) { - fprintf(stderr, "Unable to bind socket to any addresses.\n"); + guacd_log_error("Unable to bind socket to any addresses.\n"); exit(EXIT_FAILURE); } @@ -295,7 +295,7 @@ int main(int argc, char* argv[]) { /* If error, fail */ if (daemon_pid == -1) { - fprintf(stderr, "Error forking daemon process: %s\n", strerror(errno)); + guacd_log_error("Error forking daemon process: %s\n", strerror(errno)); exit(EXIT_FAILURE); } @@ -313,7 +313,7 @@ int main(int argc, char* argv[]) { /* Warn on failure */ else { - fprintf(stderr, "WARNING: Could not write PID file: %s\n", strerror(errno)); + guacd_log_error("Could not write PID file: %s\n", strerror(errno)); exit(EXIT_FAILURE); } @@ -327,12 +327,12 @@ int main(int argc, char* argv[]) { /* Ignore SIGPIPE */ if (signal(SIGPIPE, SIG_IGN) == SIG_ERR) { - syslog(LOG_ERR, "Could not set handler for SIGPIPE to ignore.
