Official disclaimer: Many things can happen, 502 errors fly around your ears, wiki-to-print is not a product :) as long as it keeps running we're happy.

BUT...

If you're stuck, this may be of use.

Running wiki-to-print as a background process

Wiki-to-print is a Flask application that runs in the background as a service, using a systemd service file. 

$ sudo service wiki2print status

$ sudo service wiki2print start
$ sudo service wiki2print stop
$ sudo service wiki2print restart

For debugging (on the server)

Stop the wiki2print service: 

$ sudo service wiki2print stop

Then run wiki-to-print manually from the folder where it is installed. First go to this folder: 

$ cd /var/www/wiki-to-print/wiki-to-print/

And then run the application: 

$ make server

And if needed, you can add print statements in the python files to dive deeper into the code.

For debugging (through a local installation)

$ git clone ssh://gitea@vvvvvvaria.org:12345/varia/wiki-to-print.git

$ cd wiki-to-print/wiki-to-print/web-interface/

$ make setup

$ make local

jobrunner

There is a script called jobrunner.sh in /var/www/html/wiki/ that is based on: https://www.mediawiki.org/wiki/Manual:Job_queue#Continuous_service

It runs the MediaWiki maintenance script RunJobs.php every 10 seconds.

It is installed on CC and runs in the background as a systemd service, called "jobrunner", which can be used with: 

$ sudo service jobrunner status
$ sudo service jobrunner start
$ sudo service jobrunner stop
$ sudo service jobrunner reload
  • The service is configured at: /etc/systemd/system/jobrunner.service
  • This is an example of the service file:
