Hi,
as promised yesterday, here is a patch that drops the explicit methods
given in the udev config and implement only one type of rule.
A rule now consists only of a number of keys to match. All known keys
are valid in any combination. The former configs should work with a few
changes:
o the "<METHOD>, " at the beginning of the line should be removed
o the result of the externel program is matched with RESULT= instead if ID=
the PROGRAM= key is only valid if the program exits with zero
(just exit with nozero in a script if the rule should not match)
o rules are processed in order they appear in the file, no priority
o if NAME="" is given, udev is instructed to ignore this device,
no node will be created
EXAMPLE:
# combined BUS, SYSFS and KERNEL
BUS="usb", KERNEL="video*", SYSFS_model="Creative Labs WebCam*", NAME="test/webcam%n"
# exec script only for the first ide drive (hda), all other will be skipped
BUS="ide", KERNEL="hda*", PROGRAM="/home/kay/src/udev.kay/extras/ide-devfs.sh %k %b %n", RESULT="hd*", NAME="%1c", SYMLINK="%2c %3c"
The udev-test.pl and test.block works fine here.
Please adapt your config and give it a try.
thanks,
Kay

Here is a slightly better version of the patch.
After a conversation with Patrick, we are now able to execute the PROGRAM
and also match in all following rules with the RESULT value from this exec.
EXAMPLE:
We have 7 rules with RESULT and 2 with PROGRAM.
Only the 5th rule matches with the callout result from the exec in the 4th rule.
RULES:
PROGRAM="/bin/echo abc", RESULT="no_match", NAME="web-no-2"¶
KERNEL="video*", RESULT="123", NAME="web-no-3"¶
KERNEL="video*", RESULT="123", NAME="web-no-4"¶
PROGRAM="/bin/echo 123", RESULT="no_match", NAME="web-no-5"¶

Thanks a lot. I've applied this patch. I also made a few tweaks to the
parsing logic to help catch old rules files properly (otherwise we end
up creating rules that the user might not have wanted.) I also cleaned
up the other test scripts and the config files.
Care to update the documentation so we can make a release for others to
play with?
thanks,
greg k-h

Yes, I'll update the man page in the next two hours :)

Nice, that sped things up quite a bit.
Running with PROGRAM="/sbin/scsi_id" with 70 lines each of the form:
BUS="scsi", PROGRAM="/sbin/scsi_id", RESULT="SIBM OEM DCHS09X 68136581", NAME="disk-sda"
BUS="scsi", PROGRAM="/sbin/scsi_id", RESULT="3600a0b80000b174b000000e83efc5d38", NAME="disk-sdaa"
...
Took 1m16 to run the udev/test/test.block test script (with 70 sd's in
/sys/block).
Using the new method, and having only one PROGRAM="/sbin/scsi_id" for the
first scsi rule, and just RESULT for the other 69, test.block took 47
seconds.
