This style of request driven programming that the shim enables with a powerful level of privilege dropping each time should be useful. The spec is also pretty easy to parse and even write for this too. It’s getting slightly hard to validate mentally, so a general purpose validation function is written to validate it programattically before launching (Specification::validate). Built the echo example, still in C, ready to be demoed with the shim (examples/echo/echo.c).\nStarted preparing a specification for the echo server (examples/echo/spec.json). This is a work in process to test new features added to the spec format, it doesn’t run yet and needs additional support before it will. Having some trouble nailing down an abstraction of networking that provides enough for existing apps to work, and also supports new apps in a nice and abstract way. I think this might result in two methods: an IP-network firewall based method for outbound traffic, e.g. this process should be able to access my database network on §10.152.163.0/24` but not the public Internet. Then a second abstraction, perhaps in the form of give me specific ports, that allows inbound traffic. Not clear yet though. The specification format still feels pretty good for a more complex app like this, even if it is getting a tad verbose. The dataflow created here of App Listener -\u003e Shim -\u003e n*Request Handler feels pretty good for any request driven development. Although the listener could probably be a library function, it’s still neat to write and simplifies the C program significantly, while providing good isolation between the two. Started work on integrating this solution more tightly with a language (in this case, Rust).\nLooking into a macro based solution, but I’m not sure it’s that much superior to straight up code. Unfortunately going anywhere near writing macros was causing my IDE to crash, so this needs to be solved before looking more into it. Care must be taken that the language specific bits don’t overtake the language agnostic bits. Multi-Process Monitor (forktop) Mixed progress on this one. On trying to write a Terminal User Interface for this one, I was disappointed with the available options. Therefore I started writing my own… (stateful-tui).\nHas support for use\\_state, a hook that allows TUI components to store state over multiple renders. Has support for use\\_effect, giving the components the ability to run arbitrary asynchronous code when things change. Has partial support for component children, allowing composition of components. Has no (but requires) support for keyboard/mouse input. Keyboard is definitely a requirement. This should be easy to implement… Though this now has a project locality value of three (shim -\u003e forktop -\u003e stateful-tui), I think it is a valuable addition to the OSS ecosystem.\nSummary It’s been a slow couple of weeks, but the groundwork has been laid for some good progress to come now.\nUp Next Now that the design of the networking system is starting to be figured out, it’s time to implement it. By next time I MUST have implemented the echo server under the shim. A design for filesystem access MUST be made. This is going to involve research into how others do it, given that it’s such a complex area. Getting forktop to a viewing stage, if not an interactive stage, SHOULD be completed. Modules Introduction to Systems Research Read Borg (Verma et al., 2015), Fuxi (Zhang et al., 2014), and Firmament (Gog et al., 2016). Reviewed Borg. Read MapReduce (Dean and Ghemawat., 2004), Dryad (Isard et al., 2007), and Pregel (Malewicz et al., 2010). Presented MapReduce. Exciting stuff here, the cluster scheduling stuff in particular is very cool. Lightweight cgroup containers have been popular for some time, and I think these readings do give good context for this project.
