2009-02-23Allow watch handle to be stored in the udevdb.Scott James Remnant
2009-02-23Cleanup a little.Scott James Remnant
Move some of the checks into udev_watch_begin() and udev_watch_clear() so we don't have to repeat them all the time.
2009-02-23Clear existing inotify watch before processing.Scott James Remnant
Likewise when re-processing an event, we want to drop the existing inotify watch first to avoid side-effects.
2009-02-23Don't add inotify watch until RUN rules processed.Scott James Remnant
The programs we RUN can open device nodes, and thus we can end up chasing our own tail.

2009-02-11udevd: optionally watch device nodes with inotifyScott James Remnant
This allows you to re-process the rules if the content of the device has been changed, most useful for block subsystem to cause vol_id to be run again.

2009-01-21reap children fasterOlaf Kirch
udevd's event_queue_manager loop is pretty sensitive to the delays of exiting child processes. I found that it helps boot times if we try to reap children as quickly as possible. This patch changes event_queue_manager to call sigchilds_waiting if it finds a signal has been received. Signed-off-by: Olaf Kirch <okir@suse.de>

2009-01-20Expose delayed name resolutionScott James Remnant
udevd had the ability to delay name resolution until the event, but this was never exposed. Add a --resolve-names=late option to do so.
2009-01-20Allow user and group lookup to be disabled.Scott James Remnant
In certain cut-down situations such as an installer or inside the initramfs, we simply don't have any kind of name service. While we could use rules without OWNER or GROUP, it's better to have the same rules as a full system and have udevd ignore those parts of the rules. Adds a --resolve-names=never switch to udevd that has this effect.
2009-01-20udevd: use ppoll instead of signal pipesOlaf Kirch
udevd uses a rather old-fashioned way of handling signals while waiting for input through select (ie by using an unnamed pipe, to which the signal handler writes one byte for every signal received). This is rather awkward and may potentially even block if we receive more signals than the kernel's pipe buffer. This patch replaces all of that with ppoll, which was designed for this purpose. It also removes the SA_RESTART flag from all installed signal handlers, because otherwise the ppoll call would just be restarted after handling eg a SIGCHLD. Signed-off-by: Olaf Kirch <okir@suse.de>
2009-01-16remove stray initializerAlan Jenkins
Picked up by "gcc -Wextra". udevadm.c:83: warning: initialized field overwritten udevadm.c:83: warning: (near initialization for ‘cmds[2].help’) This is just a cleanup. It doesn't change the code generated by gcc.

2009-01-16cleanup old names before creating the new namesKay Sievers
Scott found that the node /dev/pktcdvd can not be replaced by /dev/pktcdvd/control by changing the rules, and re-trigger the event. We used to create the new names before we cleaned up the old ones, which can not work if we need to create subdir with the same name.
2009-01-16remove name from index if the node name has changedKay Sievers
Scott discovered that a changed rule, which renames a device node leaves the old node name around as a symlink. So drop the reference to the old name.
2009-01-15udevadm: test - remove --force optionKay Sievers
Since a while we change the database with a "test" run, but do not update the node and symlinks. We need to "force" all the time, to keep things in sync.
2009-01-15do not complain about a missing /etc/udev/rules.d/Kay Sievers
Scott mentioned that initramfs does not neccessarily have that directory, so do not log an error.

2008-12-06make: do not delete autotools generated file with distcleanKay Sievers
[...] running the command `make maintainer-clean' should not delete `configure' even if `configure' can be remade using a rule in the Makefile. More generally, `make maintainer-clean' should not delete anything that needs to exist in order to run `configure' and then begin to build the program. This is the only exception; `maintainer-clean' should delete everything else that can be rebuilt.
