[Phpwiki-talk] cron jobs

[Steve W. <sw...@wc...>]

This week I figured out how to create the standalone PHP binary (just
compile it without a server option). I wrote a little test script that
read config.php and called the database to see if IsWikiPage() returned
the right value.

If we find the need to move certain database tasks out of the realm of Web
transactions and into crontabs, we should do this. I think it should be
viewed as an add-on the admin will have to take extra responsibility for;
in other words, PhpWiki should always work "out of the box" on a stock PHP
installation, and should not require cron jobs to function in the long
term.

However there are needs arising like: a permanent archive might need
periodic housekeeping, like deleting pages older than ten versions ago.
This can be done with a cron script.

We'd need simple instructions on setting this up (compile a PHP binary and
put it in /usr/local/bin/ for example), and a scripts directory for cron
jobs (maybe).

I think this will open some new possibilities to us.

I assume that especially with email notofication (e.g. once a day), more=20

a need for something like this arises.

How about deleting the 10th version when inserting the 11th? No need to=20
move this into a cronjob.

I agree.

Btw, there is a simple hack if you are not allowed to execute cron jobs:
use a page that gets called at certain intervals. E.g. I monitor the=20
availibilty of one of my sites with http://uptime.arsdigita.com/uptime/
Uptime requests a certain page about every 20 minutes. All you need to do=
=20
is check the time and then perform your "cronjob" :o)

	Or [newbie idea # xxxx]: How about deleting the Nth
version, where N = $keep_level, to be defined in config.php? (and
$keep_level == 0 never deletes).

	Very nice. Is it generally dependable in your experience?

Well, I guess the intention of Uptime is not to use it as "cronjob" but=20
really check the Uptime of your site. I've been using the service for clo=

to a year now and it is reliable. I would not bet my life that there is a=
=20
check at least every 20 minutes. I recall times between checks up to 35=20
minutes.
