0529e2ed2e [PATCH] check for empty symlink string
Attached is a patch for udev-add.c to ignore empty symlink string parts.
Issue was brought up by ide-devfs.sh with only one symlink returned, while two are expected.

bcbe2d8e7d [PATCH] libsysfs 0.4.0 patch
Ananth released sysfsutils 0.4.0 last night, I'm sure you saw the email.
Here's a patch with the latest changes from the pre-patch I already
gave you. It includes sysfs_get_device_parent(), which you said you
needed. I've run your test scripts and I've built scsi_id. Please
play around with this and check it out.

There are quite a few changes. Please do not access
structure pointers, like sysfs_device's parent, directly like
dev->parent. Please use the "get" function to retrieve. The functions
load things on demand and refresh views under the covers.

5d4754f195 [PATCH] pre-libsysfs-0.4.0 patch
I am sending you a pre-release patch. It's everything that's in our
current CVS tree. It adds the functionality you've been looking for. Please
play with this before checking it into your tree, I'd like to know if
it's ok with you or if you find problems. I have tested this out with
test.all and the perl regression test. Let me know what you think.

Still need to do more testing for our work and add some more functions
related to the changes.

I've gone into namedev.c and udev-add.c to make the necessary changes
in line with the library. I have not gone and edited any of the "extras".


Changes:

1) Libsysfs object structures work more as handles now, their included
directories or devices are labeled private. If you need attributes
from a sysfs_class_device, call the available function and don't access
the directory directly. Same holds true for a sysfs_class_device
sysfs_device. Do not access the link directly but call the function
sysfs_get_classdev_device() instead. We only populate entries upon
request, makes things faster and uses less memory.

2) Added sysfs_get_classdev_parent() as requested.

3) Changed getpagesize to sysconf.

4) Added sysfs_refresh_attributes function for refreshing views of
attribute lists. We still need to add refresh for links and subdirs. All
udev needs to do is keep calling sysfs_get_classdev_attr() and that will
internally call the refresh routine.

4763256c65 [PATCH] allow multiple symlinks
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:

5aebfbcb62 [PATCH] D-BUS patch for udev-008
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.

c332cfc72d [PATCH] udev: sleep_for_dev() bits
OK, I fixed that bug you hinted at earlier in my previous
sleep_for_dev() patch.  I am sure you fixed it, but here we go
nonetheless, just in case.

I actually changed it up a bit.  It is probably faster to count down
from SECONDS_TO_WAIT_FOR_DEV than count up.

I also made the lone 'path' argument const, since it can be.

Some other misc. bits, too.

8e41d35d76 [PATCH] udevdb prototype
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.
