Cron is not running

[Michael Wuttke]

Mahara v1.4rc3
Linux 2.6.26-2
PHP 5.2.6
Apache-Server 2.2.9
postgresql-Server 8.4

I was trying to setup the cronjob for mahara explained like in the wiki: https://wiki.mahara.org/index.php/System_Administrator%27s_Guide/Cron_Job. But it do not work.

See the entry in the /etc/crontab:
 */5 * * * * www-data php -c /etc/php5/apache2/php.ini /data/srv/www/mahara/lib/cron.php >> /var/log/mahara/cron.log 2>&1

and the output of log-file in /var/log/mahara/cron.log:
"A nonrecoverable error occured. This probably means you have encountered a bug in the system[WAR] 1f (lib/web.php:2291) redirect() should be called with either /[something] for local redirects or http[something] for absolute redirects
Call stack (most recent first):
  * redirect("ar/www/mahara/lib/cron.php") at /var/www/mahara/init.php:192
  * require("/var/www/mahara/init.php") at /var/www/mahara/lib/cron.php:33

A nonrecoverable error occured. This probably means you have encountered a bug in the system".

Has anybody an idea?

Thanx,
michael wuttke

I can reproduce this, it's caused by the new code which attempts to redirect to https.

Hi Michael,

Thanks for reporting this bug. Someone will look into this soon.

For whoever looks into it:
There are a few things:
-The function
get_relative_script_path() (htdocs/lib/web.php:2434 (on master))
uses substr against get_script_path but giving the length of
get_mahara_install_subdirectory(), need to work out which one is needed

-The function
get_mahara_install_subdirectory (htdocs/lib/mahara.php:1993 (master))
uses strpos($wwwroot, '/'). This will return -1 if the wwwroot is
something like
https://localhost (ie. no trailing /)
This case should get picked up, because init.php adds a '/' at end if
there isn't one.

Cheers,

Hugh

Hi Michael

Can you please attach your config.php file? I'd like to see what config options you are overriding.

Remove any sensitive information such as the database password first.

Thanks
Darryl

    Revert "Remove wwwroot from the database (bug #780177)"

    This reverts commit fb38dd955ceed3601da954dd5b2e55b682e1ac03.

    It turns out that we do need the wwwroot to be in the database
    because the code that sends forum posts via email runs in php
    cli mode and is needs to get the hostname of the site to embed
    in the headers.

    While not specifically mentioned in bug #794490, it was spitting
    out warnings in the logs.

Hi Michael,

I have just released 1.4rc4, would you be able to check if your cron problems are resolved?

  https://launchpad.net/mahara/+milestone/1.4rc4

Thank you so much for reporting this so quickly. You saved us from an embarrassing 1.4.0 release :)

Cheers,
Francois

[Michael Wuttke (wuttke-berlin)]

Hallo Francois,

i have installed the version 1.4rc4 and the cronjob seems to work.

See the output of log-file in /var/log/mahara/cron.log:

But in the admin-webfrontend it shows me:
"Cron: Cron is not running."

Is this related to the reported bug: https://bugs.launchpad.net/mahara/+bug/776955?

Thank you for your help,
michael

Hi Iñaki,

I've just pushed a fix for this against 1.3_STABLE:

  https://reviews.mahara.org/432

Are you able to test that patch and confirm that it solves your problem?

Cheers,

Hi François,

yes it does solve it :)

Saludos.
Iñaki.

[Ruslan Kabalin (rkabalin)]

    init: only redirect to HTTPS when running in a browser

    The redirect to HTTPS added in 02cf299a59851c06ac9227a2f0df898392196cf6
    was causing problems when cron was running using PHP cli (bug #794490).
