This is a nicer error than crashing in the depths of some error handler (which is what will happen if the DB goes unavailable while they're running), and it's a far more common case (eg. the DB is misconfigured) than having it fail halfway through. Neither of these services can do anything meaningful without the DB, so crashing without it is acceptable behaviour. |

README.md
Wubloader is a system for saving, re-serving and cutting into videos of a target twitch (or probably other HLS, but some twitch specifics are assumed) stream.
It was designed to serve the needs of the Video Strike Team as part of Desert Bus For Hope.
A full design doc can be read at initial-design-doc.pdf, but a brief overview of the components:
downloadergrabs segments from twitch and saves them to diskrestreamerserves segments from disk as well as playlist files allowing them to be streamedbackfillerqueries restreamers of other servers in order to pick up segments this server doesn't have already, ie. it replicates missing segments.cutterinteracts with a database to perform cutting jobssheetsyncsyncs specifc database columns to a google doc which is the primary operator interface.thrimshimacts as an interface between thethrimbletrimmereditor and the database.thrimbletrimmeris a browser based video editor.databasehosts a Postgres database to store events to be edited.nginxprovides a webserver through which the other components are exposed to the outside world.commonprovides code shared between the other components.monitoringprovides dashboards to allow the wubloader to be monitored.
Usage
All components are built as docker images.
Components which access the disk expect a shared directory mounted at /mnt.
A docker-compose file is provided to run all components. See docker-compose.jsonnet
to set configuration options, then generate the compose file with ./generate-docker-compose.
Then run docker-compose up.
Further details of installing and configuring the backfiller are provided in INSTALL.md.
