new hal policy file

[Andrew Telford]

I have an APC usb UPS and the process 'hald-addon-hid-ups' was slowly growing and using up all my RAM (Gentoo stable x86).

I noted that the latest release 3.14.3 installs a new hal policy file so upgraded to in the hope that it would fix things. The policy file syntax was not accepted by hal. I got an error:

hald[12708]: error in fdi file /etc/hal/fdi/policy/80-apcupsd-ups-policy.fdi:5: Bad rule: unknown type_match

I had a quick scan of the hal documents, and it appears that the first "match" tag has incorrect syntax.  Here is my patch

5c5
<     <match key="info.addons" type="strlist">hald-addon-hid-ups</match>
---
>     <match key="info.addons" contains="hald-addon-hid-ups">

Does this make sense? In any case, the process 'hald-addon-hid-ups'  does not start anymore, so apcupsd has sole access to the UPS which is what I think was supposed to happen,

What version of hald are you running? Maybe they changed the syntax
for this. The original syntax is correct and tested on RHEL5.

Sure enough, the policy file is incorrect as you say. RHEL5 uses hal-0.5.8
which has the same DTD, so it's also "wrong" on that system as well.
Strangely, though, it works just fine. I retried it just to be sure.

Anyway, I will apply your fix for apcupd-3.14.4. Thanks!
