I just played around with it a bit.
As long as the pear package is provided, the daemon can run as www-data.
Some options need to be set, and the uid and gid need to be detected. A
log file and a pid file need to be specified where the daemon can write to.
A running example modified from the simple one provided on the pear page:
http://pastebin.com/x8MBDcV1
To start it a simple
exec('/var/www/daemon.php');
is enough. Deeper integration into the system of course is not
possible, but in general a simple daemon may indeed run without much aches.

One of the design goal os ownCloud is that is should enable as many people as
possible to host an ownCloud instance. So someone with jut a webspace at a
university for example should be able to run ownCloud by just copying ownCloud
into the webspace.
A solution like this System Daemon wouldn´t run in this scenario and would
require significant more knowledge to install and run than currently.

Did you consider the option of a daemon? That could provide even a bit more
flexibility and people wouldn't need to change anything on the server.

Hi all,
after the sprint in Stuttgart I talked with Jörn Friedrich Dreyer about
the background job problem. If I remember correctly the two most
important suggestions were (a) using cron and (b) using long time
polling/ajax.
I'd suggest extending (or rewriting) "my" background jobs app so that it
can make use of both cron jobs and ajax polling. Then the app can choose
the best option out of:
1) using cron (++)
2) using some internet cron service (open the page x every y minutes) (+)
3) long time polling when the users are on the page (-)
The reasons for my rating: A normal cron job does not rely on the
limitations that apache might have (memory limit, time limit). An
internet cron service has these limitations, but it works 24/7. Option 3
runs only when users are online which is bad if you rely on having
certain tasks done at a given time.
What do you think?
Regards,
Jakob

I need a cron job system for news app too. The use case is the
following: if the user doesn't check the reader for a long time, he
might miss some items that might have been in the feed and then been
removed. This happens with feeds that have frequent updates.
I know that Jakob is working on this.

Hi all,
I was just wondering if someone is working on a kind of cronjob
system for ownCloud.
I know that there is the background job app by Jakob, but this app
requires an entry in the crontab file.
I am currently working on remote calendars and it would be quite
useful to have a cron job system, to automatically update the remote
calendars.
It would actually work without a cronjob system, if you update them
if the user is using the calendar, but a cronjob system would make it
more comfortable.
But there are some planned features, that wouldn't work without a
cronjob system.
An Example would be an automatic e-mail reminder before an event starts.
Does anybody has a clue on how I could solve this problem without
making an entry in the crontab file a hard dependency?
Cheers,
Georg Ehrke
