New Version of the IDE!

[thecodingwizard]

We updated the backend of the IDE (migrated from Firepad to YJS). This reduces costs, increases performance, and improves stability.

If you encounter any issues or have other general feedback, please leave a comment here or open a new issue.

We will continue to host the old ide at https://legacy.ide.usaco.guide/. However, please move important files to the new IDE, as we may have to shut down the legacy server eventually.

Migration Plan

Code is in the legacy-archive branch.

• Make a backup of the legacy database Done: stored in gcs cp-ide-default-rtdb-backups. Backup taken August 31, 2023, ~5pm PT. We have ~150k files!
• short term: delete any scribble / input / outputs that are > 10kb in size (note that due to firepad overhead, the actual size limit of the data is probably a lot less, maybe like 2kb).
• long term: "compress" old files: make them read-only; gzip everything; delete any scribble / input / outputs that are > 5kb in size after gzip. This probably reduces database size to < 1GB (ie. free tier)

Before: 10.5GB used. Now (after short term fix): 2.1GB

Disk Usage

Update: On Dec 20 2023, I resized it to use a 256gb ssd, of which we have used 15gb, so we should be good for now.

For the new server, this is our disk space as of May 31 2023:

Is there a way to download all of the files on the old IDE at once?

[thecodingwizard]

Not currently, but it’s probably possible to write a script to do this (?)

[programmeruser2]

Is there a simple API endpoint for enumerating workspaces/downloading files? It seems like right now it uses Firebase

[thecodingwizard]

There isn’t. You can connect to firebase manually though, and just directly read from firebase to get the info you need?
