I still need a balancing algorithm and buffering code. My design notes for the balancing algorithm look like this.
- The goal of the balancing algorithm is to always present the user the most important information.
- Important information could be the most current information or the information tagged with the highest priority level.
- The display should be stable without sudden changes or shuffles.
- That means the display is always chronological with regards to the first time a message appears.
- Each group stores its own buffer of messages.
- This means if a group starts to display errors the historical debug and info message can be pulled.
- Messages are stored as a hierarchy of message groups.
- At a high level message groups are sized based on the rate of messages they are delivering.
- That means high-frequency sources are displayed instead of low-frequency sources.
- A new message will always be displayed though. A very high frequency group will only cause low frequency groups to be hidden faster.
I want to be able to display multiple progress bars and nested progress bars as files are downloaded and packages are indexed.
Buildkit (https://github.com/moby/buildkit) has a nice implementation but there event driven model coming from internal API JSON might be too complicated at this stage.
