General:
- Switched to yarn to better work with nix-based tooling
- Switched package system to use nix. This stops double dependencies and slow cloud compile times, while providing more compile/runtime support to the Nix project
- Removed container builder in favor of internal container tooling
- Package versions no-longer need to be SemVer compliant
- Removed "piston package spec" files, replaced with nix-flake based runtimes
- Exported nosocket and piston-api as packages within the nix-flake
- Removed repo container
- Switched docker building to nix-based container outputting
- Removed docker compose as this is a single container
- Removed package commands from CLI
Packages:
- Move bash, clojure, cobol, node, python2, python3 to new format
- Remainder of packages still need to be moved
v2 API:
- Removed "version" specifier. To select specific versions, use the v3 api
- Removed "/package" endpoints as this doesn't work with the new nix-based system
v3 API:
- Duplicate of v2 API, except instead of passing in a language name an ID is used intead.
By increasing the niceness value of child processes, the scheduler gives less CPU Time to them.
This allows the node process to get more CPU time, and can work through the event queue faster.
The system used to use async.
This would result in execution is handed off to other processes.
In the case of a forkbomb was used, it could circumvent the janitor as it consumed more CPU time which would prevent the process janitor from reading the process information in.
Old process janitor required starting a `ps` process.
This was problematic, as `ps` requires another entry in the process table, which in some cases was impossible as it was exhausted.
