From c8676fad54bb0f4152947a6781626872bfa6ad64 Mon Sep 17 00:00:00 2001 From: Tamino Bauknecht Date: Tue, 12 Dec 2023 22:54:31 +0100 Subject: sway/output: Improve logging of swaybg execvp failure and more checks This doesn't catch the error if a background changing command is executed via swaymsg, but improves logging. The additional checks at least propagate if e.g. forking failed. --- sway/commands/output.c | 5 ++++- sway/config/output.c | 9 ++++++--- 2 files changed, 10 insertions(+), 4 deletions(-) diff --git a/sway/commands/output.c b/sway/commands/output.c index df32c673..462dffd2 100644 --- a/sway/commands/output.c +++ b/sway/commands/output.c @@ -111,7 +111,10 @@ struct cmd_results *cmd_output(int argc, char **argv) { if (!config->reloading && !config->validating) { apply_output_config_to_outputs(output); if (background) { - spawn_swaybg(); + if (!spawn_swaybg()) { + return cmd_results_new(CMD_FAILURE, + "Failed to apply background configuration"); + } } } diff --git a/sway/config/output.c b/sway/config/output.c index 1a5215fe..54ebaa17 100644 --- a/sway/config/output.c +++ b/sway/config/output.c @@ -822,7 +822,9 @@ static bool _spawn_swaybg(char **command) { setenv("WAYLAND_SOCKET", wayland_socket_str, true); execvp(command[0], command); - sway_log_errno(SWAY_ERROR, "execvp failed"); + sway_log_errno(SWAY_ERROR, "failed to execute '%s' " + "(background configuration probably not applied)", + command[0]); _exit(EXIT_FAILURE); } _exit(EXIT_SUCCESS); @@ -832,12 +834,13 @@ static bool _spawn_swaybg(char **command) { sway_log_errno(SWAY_ERROR, "close failed"); return false; } - if (waitpid(pid, NULL, 0) < 0) { + int fork_status = 0; + if (waitpid(pid, &fork_status, 0) < 0) { sway_log_errno(SWAY_ERROR, "waitpid failed"); return false; } - return true; + return WIFEXITED(fork_status) && WEXITSTATUS(fork_status) == EXIT_SUCCESS; } bool spawn_swaybg(void) { -- cgit v1.2.3
