2007-03-18priority based symlink handlingKay Sievers
Symlinks can have priorities now, the priority is assigned to the device and specified with OPTIONS="link_priority=100". Devices with higher priorities overwrite the symlinks of devices with lower priorities. If the device, that currently owns the link goes away, the symlink will be removed, and recreated, pointing to the next device with the highest actual priority. This should solve the issue, that inserting an USB-stick may overwrite the /dev/disk/by-id/-link of another disk, and removes the entire link after the USB-stick is disconnected. If no priorities are specified, the new link will overwrite the current one, and if the device goes away, it will restore the old link. It should be possible to assign lower priorities to removable devices, if needed. In multipath setups, we see several devices, which all connect to the same volume, and therefore all try to create the same metadata-links. The different path-devices are combined into one device-mapper device, which also contains the same metadata. It should be possible, to assign multipath-table device-mapper devices a higher priority, so path-devices that appear and disappear, will not overwrite or delete the device-mapper device links.

2007-01-23unlink old database file before creating a new oneSergey Vlasov
udev_db_add_device() can be called when the corressponding database entry already exists - it should overwrite the old entry in this case. However, if the old entry was a symlink, fopen(filename, "w") will not overwrite it properly - it will keep the symlink and create a file named after the symlink target. Calling unlink(filename) before trying to create the database file fixes the problem. Signed-off-by: Sergey Vlasov <vsu@altlinux.ru>

2006-08-21db: don't create a db file for only a node name to storeKay Sievers
2006-08-19consistent key naming to match only the event device or include all parent ↵Kay Sievers
devices This scheme is more consistent and makes it obvious if a match happens against the event device only, or the full chain of parent devices. The old key names are now: BUS -> SUBSYSTEMS ID -> KERNELS SYSFS -> ATTRS DRIVER -> DRIVERS Match keys for the event device: KERNEL SUBSYSTEM ATTR DRIVER (in a future release, for now the same as DRIVERS) Match keys for all devices along the parent device chain: KERNELS SUBSYSTEMS ATTRS DRIVERS ID, BUS, SYSFS are no longer mentioned in the man page but still work. DRIVER must be converted to DRIVERS to match the new scheme. For now, an error is logged, if DRIVER is used. In a future release, the DRIVER key behaviour will change.
2006-08-18db: store devpath - node relationship for all devicesKay Sievers
If we don't have any interesting values to store, we just use a symlink (doesn't occupy a whole page on tmpfs like a file) to store the name of the node belonging to a devpath. This will allow udevinfo to resolve all names, even when we don't have a full database entry.
2006-01-09replace libsysfsKay Sievers
We never used any of the libsysfs convenience features. Here we replace it completely with 300 lines of code, which are much simpler and a bit faster cause udev(d) does not open any syfs file for a simple event which does not need any parent device information.

All udev state is kept in /$udev_root/.udev/ now. No option to configure that anymore, it will always be there. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

HAL soon wants to read the whole content of the udevdatabase while starting up. This makes the whole udev structure available to the udevinfo "dump". Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2005-07-05create udevdb files only if somehting interesting happenedKay Sievers
Device nodes created with the default rule, without any symlink or option are no longer saved to the udevdb. This saves us ~3 MB RAM for pretty much useless files on tmpfs. Note: HAL needs a fix to handle this correctly. It's already available on the list. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2005-04-26[PATCH] fix klibc's broken strlcpy/strlcatkay.sievers@vrfy.org
udevinfo segfaults cause klibc's strlcpy writes behind the specified size of the destination string. strlcat truncates the destination string which is also not what you expect from a concatenation function.

Some broken ide drivers are generating high event traffic, with add/remove events. With this attribute, it can be specified, that the node is always available. It may be used in conjunction with the new DRIVER= match to catch specific kernel device drivers.
