From 3c0bab4aaf70b2383aa4cbabf6059c48744e8960 Mon Sep 17 00:00:00 2001 From: Tom Gundersen Date: Fri, 6 Mar 2015 18:22:35 +0100 Subject: [PATCH 1/1] udevd: event - make db loading lazy in REMOVE event handling We were explicitly eagerly loading the db, then deletenig the backing file and then processing the rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be lazy as everywhere else. This may save us a bit of work in casese where the db is not needed, but more importantly it hides some implementation details of libudev-device form udevd. --- src/libudev/libudev-device-private.c | 1 + src/udev/udev-event.c | 7 +++---- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/src/libudev/libudev-device-private.c b/src/libudev/libudev-device-private.c index 15d3b231c..e59028874 100644 --- a/src/libudev/libudev-device-private.c +++ b/src/libudev/libudev-device-private.c @@ -182,6 +182,7 @@ int udev_device_delete_db(struct udev_device *udev_device) if (id == NULL) return -1; strscpyl(filename, sizeof(filename), "/run/udev/data/", id, NULL); + unlink(filename); return 0; } diff --git a/src/udev/udev-event.c b/src/udev/udev-event.c index b96cf737f..4ca73d3db 100644 --- a/src/udev/udev-event.c +++ b/src/udev/udev-event.c @@ -793,10 +793,6 @@ void udev_event_execute_rules(struct udev_event *event, return; if (streq(udev_device_get_action(dev), "remove")) { - udev_device_read_db(dev); - udev_device_delete_db(dev); - udev_device_tag_index(dev, NULL, false); - if (major(udev_device_get_devnum(dev)) != 0) udev_watch_end(event->udev, dev); @@ -807,6 +803,9 @@ void udev_event_execute_rules(struct udev_event *event, if (major(udev_device_get_devnum(dev)) != 0) udev_node_remove(dev); + + udev_device_delete_db(dev); + udev_device_tag_index(dev, NULL, false); } else { event->dev_db = udev_device_shallow_clone(dev); if (event->dev_db != NULL) { -- 2.30.2
