[FIXED] Power saving issue with 0.5.0 beta 1

[elmer91]

I was using SAB 0.4.x for a very long time.
It was running on a small Linux server (Synology NAS) without any problem.

I have configured the watched folder to a RAM drive / no RSS.
When SABnzbd became idle, my hard drives correctly enter power save mode after a while.

I recently tested 0.5.0 beta 1 (working very well)
Configuration was exactly the same. But my hard drives never enter power save mode.

I guess there is some hard disk access. But I'm able to locate the feature causing this.
I checked the logs, nothing after SAB has entered idle state.

I checked also starting SAB with empty queue: same thing, no power save.

Do you have any hints about it ?
Thanks.

First make sure logging is set to the lowest level.
Further we have now a scheduled "pause-all" which should
prevent all disk access.
We're not aware of any disk access, but it's hard to tell for sure.
(One problem is that we use quite a number of third-party modules
which lead their own internal lives).

Thanks for your answer,

I have already checked logs.
Nothing is logged after SAB has finished downloading.

Logging is set to "Errors/warnings"

I will try to find a Linux tool able to monitor hard disk /file acces.
I will report any progress in this direction.

Thanks for your help.

I have found (at least) one thing:
RSS module is saving its state periodically.

In my config file, RSS checks is set to 15 mn
I have no RSS feed set.

In 0.4.x series, no problem.
In 0.5.0 beta 1, RSS module is saving its state.

I enabled debug logs, following lines appear every 15mn:
2009-12-07 15:48:21,428::INFO::[__init__:635] Saving data for rss_data.sab in /volume1/download/news/cache/rss_data.sab
2009-12-07 16:03:21,498::INFO::[__init__:635] Saving data for rss_data.sab in /volume1/download/news/cache/rss_data.sab

Setting RSS checking interval to a huge value can do the trick.
(may be 0, i have to check the source)


Would it be possible not to write rss_data.sab when there is nothing to write ?

Thanks for doing the hard work for this problem. 
I'll fix this for the next Beta.

rss.py line 365:

            if type(feeds) != type({}):
                self.save()

Works !

It's a little more complex than that.
You want to save when any feed definition is active,
because you can have inactive ones too.
But it's no big deal, will make it to Beta2.
