asked to perform often.

title: Paste

Paste

Paste servers are an easy way to share long-form content such as configuration files or log data with others over short-form communication protocols such as IRC. OpenStack runs the "lodgeit" paste software.

Overview

For OpenStack we use a fork of lodgeit which is based on one with bugfixes maintained by dcolish but adds back missing anti-spam features required by OpenStack.

Ansible configures lodgeit to use mariadb database backend, apache as a front-end proxy.

Manual Administrative Tasks

Deleting a Paste

The quickest way to do this is database surgery. Lodgeit uses a MariaDB container on the paste server, and only has a single table in its database, so this is quite straightforward. Connect to the database with an interactive client session like so:

sudo docker-compose -f /etc/lodgeit-compose/docker-compose.yaml exec \
  mariadb bash -c '/usr/bin/mysql -uroot -p"$MYSQL_ROOT_PASSWORD" lodgeit'

These days we've configured Lodgeit to use so-called "private" identifiers by default, so that's what you'll likely be keying from. For the sake of example let's pretend the URL is https://paste.opendev.org/show/thisIsSomeMadeUpBlob/. First check the row you're about to delete:

SELECT code FROM pastes WHERE private_id='thisIsSomeMadeUpBlob';

Note that if you instead have an old-style integer index identifier, you'll need to use paste_id with that instead of private_id. You should see the code field content from one row matching the content of the page you're preparing to delete. If it looks correct, proceed with the deletion:

DELETE FROM pastes WHERE private_id='thisIsSomeMadeUpBlob';

That command should return a response like 1 row in set (0.001 sec) if it was successful. Try to load the paste in your browser again and hopefully it now says PageNot Found instead of returning the prior content. If all's as intended, ^D out of the interactive shell and you're done!
