I've created a logging.h file and moved the debug macros from udev.h in there. If you type: 'make' - you will get a binary that prints one or two lines to syslog if a device node is created or deleted 'make LOG=false' - you get a binary that prints asolutely nothing 'make DEBUG=true' - the same as today, it will print all debug lines
2005-04-26[PATCH] small cleanup udev-remove.ckay.sievers@vrfy.org
Here is a small cleanup. It replaces the malloc in udev-remove.c with a struct, like we do in udev-add.c
2005-04-26[PATCH] udev-remove.c cleanupskay.sievers@vrfy.org
I've moved the malloc out of the udevdb into udev-remove to free the struct after use and not to allocate a different struct in the case the device is not in the data base. I seems a bit easier to read.
2005-04-26[PATCH] bug in udev-remove.ckay.sievers@vrfy.org
Uups, we have a bug in udev-remove.c. udev segfaults with NULL-pointer, if the device is not in the database: ./test.block: line 29: 4844 Segmentation fault $BIN block Dec 17 22:47:42 pim udev[4882]: udev_remove_device: '/block/sdy' not found in database, falling back on default name Dec 17 22:47:42 pim udev[4882]: udev_remove_device: name is '(null)'
2005-04-26[PATCH] allow multiple symlinkskay.sievers@vrfy.org
Here is a patch to allow the creation of multiple symlinks. The names must be separated by a space character. REPLACE, KERNEL="ttyUSB0", NAME="visor", SYMLINK="first-%n second-%n third-%n" results in: Dec 9 05:28:51 pim udev[12019]: create_node: mknod(udev-root/visor, 020666, 188, 0) Dec 9 05:28:51 pim udev[12019]: create_node: symlink 'udev-root/first-0' to node 'visor' requested Dec 9 05:28:51 pim udev[12019]: create_node: symlink(./visor, udev-root/first-0) Dec 9 05:28:51 pim udev[12019]: create_node: symlink 'udev-root/second-0' to node 'visor' requested Dec 9 05:28:51 pim udev[12019]: create_node: symlink(./visor, udev-root/second-0) Dec 9 05:28:51 pim udev[12019]: create_node: symlink 'udev-root/third-0' to node 'visor' requested Dec 9 05:28:51 pim udev[12019]: create_node: symlink(./visor, udev-root/third-0)

2005-04-26[PATCH] D-BUS patch for udev-008david@fubar.dk
Attached is a patch against udev-008 to send out a D-BUS message when a device node is added or removed. Using D-BUS lingo, udev acquires the org.kernel.udev service and sends out a NodeCreated or NodeDeleted signal on the org.kernel.udev.NodeMonitor interface. Each signal carries two parameters: the node in question and the corresponding sysfs path. [Note: the D-BUS concepts of service, interface, object can be a bit confusing at first glance] An example program listening for these messages looks like this #!/usr/bin/python import dbus import gtk def udev_signal_received(dbus_iface, member, service, object_path, message): [filename, sysfs_path] = message.get_args_list() if member=='NodeCreated': print 'Node %s created for %s'%(filename, sysfs_path) elif member=='NodeDeleted': print 'Node %s deleted for %s'%(filename, sysfs_path) def main(): bus = dbus.Bus(dbus.Bus.TYPE_SYSTEM) bus.add_signal_receiver(udev_signal_received, 'org.kernel.udev.NodeMonitor', # interface 'org.kernel.udev', # service '/org/kernel/udev/NodeMonitor') # object gtk.mainloop() if __name__ == '__main__': main() and this is the output when hot-plugging some usb-storage. [david@laptop udev-008]$ ~/node_monitor.py Node /udev/sda created for /block/sda Node /udev/sda1 created for /block/sda/sda1 Node /udev/sda1 deleted for /block/sda/sda1 Node /udev/sda deleted for /block/sda The patch requires D-BUS 0.20 or later while the python example program requires D-BUS from CVS as I only recently applied a patch against the python bindings.

2005-04-26[PATCH] major database cleanupsgreg@kroah.com
Now we standardise on a struct udevice to pass around, and store in the database. This cleaned up the database code a lot.
2005-04-26[PATCH] more database work. Now we only store the info we really need right now.greg@kroah.com
Also delete the record after the device is gone, and fix up a memory leak.
2005-04-26[PATCH] got "remove of named devices" working.greg@kroah.com
database code still needs some major cleanup.
2005-04-26[PATCH] udevdb prototypedsteklof@us.ibm.com
Here's an "idea" of what I had in mind for udevdb. Let me preface the code with a few remarks: 1) I was expecting to write this udevdb for udev to keep track of devices. I was planning an external package that depends upon udev to provide an external API to the udevdb database. The calls for the interface would be read only access. Not sure how you want to do packaging, if having a separate package is ok or having it included in udev. 2) I created it as it is because udev isn't a daemon. So, the open database call doesn't take any parameters. My plan was to create a udevdb_init function that took arguments for initializing the db to start, where you could specify in memory only or a file location. This can all be filled in. 3) I hacked the Makefile to get it to work. Not sure how you'd want that in the future. 4) This assumes TDB has been installed elsewhere, you would need to edit your Makefile and point it to the header and library locations. How do you want to do TDB in udev? Do you want to just reference it and make udev dependent on that package being installed. Or should we do what samba does and include a limited tdb version in udev? 5) Again, I hacked udev into your existing code. In the future, I'd probably make a function around the filling out the udevice before calling the store command. Didn't know if you wanted to change your add device function to use struct udevice rather than having everything separate. 6) Not sure what we should include in the udevice structure that's stored by udev. I made a stab at a first shot - we can add and remove of course, this was a first pass. I've come to realize - with you including libsysfs in udev, the "external" interface that references udevdb could make use of getting information from through libsysfs from sysfs and doesn't need to be in udevdb. 7) I could write a namedevdb for namedev's device management if you wanted.
