From 5a24ed2bf2b4826a41542e03449d96ddd6ab63e0 Mon Sep 17 00:00:00 2001 From: Oscar Cowdery Lack Date: Mon, 7 Jan 2019 22:48:42 +1100 Subject: swayidle: Fix sleep inhibitor not being acquired Fixes #3377. The sleep lock file descriptor was immediately closed after it was acquired due to the dbus message being freed. Now the fd is duplicated before the message is freed so the inhibitor stays active. --- swayidle/main.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'swayidle/main.c') diff --git a/swayidle/main.c b/swayidle/main.c index 9a76e58c..41eecc41 100644 --- a/swayidle/main.c +++ b/swayidle/main.c @@ -1,6 +1,7 @@ #define _POSIX_C_SOURCE 200809L #include #include +#include #include #include #include @@ -104,9 +105,21 @@ static void acquire_sleep_lock(void) { if (ret < 0) { wlr_log(WLR_ERROR, "Failed to parse D-Bus response for Inhibit: %s", strerror(-ret)); + sd_bus_error_free(&error); + sd_bus_message_unref(msg); + return; } else { wlr_log(WLR_INFO, "Got sleep lock: %d", lock_fd); } + + // sd_bus_message_unref closes the file descriptor so we need + // to copy it beforehand + lock_fd = fcntl(lock_fd, F_DUPFD_CLOEXEC, 3); + if (lock_fd < 0) { + wlr_log(WLR_ERROR, "Failed to copy sleep lock fd: %s", + strerror(errno)); + } + sd_bus_error_free(&error); sd_bus_message_unref(msg); } -- cgit v1.2.3
