This codebase tries to</span> +<span class="Comment">; make this possible for its readers. (More details: <a href="http://akkartik.name/about">http://akkartik.name/about</a>)</span> +<span class="Comment">;</span> +<span class="Comment">; What helps comprehend the global structure of programs? For starters, let's</span> +<span class="Comment">; enumerate what doesn't: idiomatic code, adherence to a style guide or naming</span> +<span class="Comment">; convention, consistent indentation, API documentation for each class, etc.</span> +<span class="Comment">; These conventional considerations improve matters in the small, but don't</span> +<span class="Comment">; help understand global organization. They help existing programmers manage</span> +<span class="Comment">; day-to-day operations, but they can't turn outsider programmers into</span> +<span class="Comment">; insiders. (Elaboration: <a href="http://akkartik.name/post/readable-bad">http://akkartik.name/post/readable-bad</a>)</span> +<span class="Comment">;</span> +<span class="Comment">; In my experience, two things have improved matters so far: version control</span> +<span class="Comment">; and automated tests. Version control lets me rewind back to earlier, simpler</span> +<span class="Comment">; times when the codebase was simpler, when its core skeleton was easier to</span> +<span class="Comment">; ascertain. Indeed, arguably what came first is by definition the skeleton of</span> +<span class="Comment">; a program, modulo major rewrites. Once you understand the skeleton, it</span> +<span class="Comment">; becomes tractable to 'play back' later major features one by one. (Previous</span> +<span class="Comment">; project that fleshed out this idea: <a href="http://akkartik.name/post/wart-layers">http://akkartik.name/post/wart-layers</a>)</span> +<span class="Comment">;</span> +<span class="Comment">; The second and biggest boost to comprehension comes from tests. Tests are</span> +<span class="Comment">; good for writers for well-understood reasons: they avoid regressions, and</span> +<span class="Comment">; they can influence code to be more decoupled and easier to change. In</span> +<span class="Comment">; addition, tests are also good for the outsider reader because they permit</span> +<span class="Comment">; active reading. If you can't build a program and run its tests it can't help</span> +<span class="Comment">; you understand it. It hangs limp at best, and might even be actively</span> +<span class="Comment">; misleading. If you can run its tests, however, it comes alive. You can step</span> +<span class="Comment">; through scenarios in a debugger. You can add logging and scan logs to make</span> +<span class="Comment">; sense of them. You can run what-if scenarios: "why is this line not written</span> +<span class="Comment">; like this?" Make a change, rerun tests: "Oh, that's why." (Elaboration:</span> +<span class="Comment">; <a href="http://akkartik.name/post/literate-programming">http://akkartik.name/post/literate-programming</a>)</span> +<span class="Comment">;</span> +<span class="Comment">; However, tests are only useful to the extent that they exist. Think back to</span> +<span class="Comment">; your most recent codebase. Do you feel comfortable releasing a new version</span> +<span class="Comment">; just because the tests pass? I'm not aware of any such project. There's just</span> +<span class="Comment">; too many situations envisaged by the authors that were never encoded in a</span> +<span class="Comment">; test. Even disciplined authors can't test for performance or race conditions</span> +<span class="Comment">; or fault tolerance. If a line is phrased just so because of some subtle</span> +<span class="Comment">; performance consideration, it's hard to communicate to newcomers.</span> +<span class="Comment">;</span> +<span class="Comment">; This isn't an arcane problem, and it isn't just a matter of altruism. As</span> +<span class="Comment">; more and more such implicit considerations proliferate, and as the original</span> +<span class="Comment">; authors are replaced by latecomers for day-to-day operations, knowledge is</span> +<span class="Comment">; actively forgotten and lost. The once-pristine codebase turns into legacy</span> +<span class="Comment">; code that is hard to modify without expensive and stress-inducing</span> +<span class="Comment">; regressions.</span> +<span class="Comment">;</span> +<span class="Comment">; How to write tests for performance, fault tolerance, race conditions, etc.?</span> +<span class="Comment">; How can we state and verify that a codepath doesn't ever perform memory</span> +<span class="Comment">; allocation, or write to disk? It requires better, more observable primitives</span> +<span class="Comment">; than we currently have. Modern operating systems have their roots in the</span> +<span class="Comment">; 70s. Their interfaces were not designed to be testable. They provide no way</span> +<span class="Comment">; to simulate a full disk, or a specific sequence of writes from different</span> +<span class="Comment">; threads. We need something better.</span> +<span class="Comment">;</span> +<span class="Comment">; This project tries to move, groping, towards that 'something better', a</span> +<span class="Comment">; platform that is both thoroughly tested and allows programs written for it</span> +<span class="Comment">; to be thoroughly tested. It tries to answer the question:</span> +<span class="Comment">;</span> +<span class="Comment">; If Denis Ritchie and Ken Thompson were to set out today to co-design unix</span> +<span class="Comment">; and C, knowing what we know about automated tests, what would they do</span> +<span class="Comment">; differently?</span> +<span class="Comment">;</span> +<span class="Comment">; To try to impose *some* constraints on this gigantic yak-shave, we'll try to</span> +<span class="Comment">; keep both language and OS as simple as possible, focused entirely on</span> +<span class="Comment">; permitting more kinds of tests, on first *collecting* all the information</span> +<span class="Comment">; about implicit considerations in some form so that readers and tools can</span> +<span class="Comment">; have at least some hope of making sense of it.</span> +<span class="Comment">;</span> +<span class="Comment">; The initial language will be just assembly. We'll try to make it convenient</span> +<span class="Comment">; to program in with some simple localized rewrite rules inspired by lisp</span> +<span class="Comment">; macros and literate programming. Programmers will have to do their own</span> +<span class="Comment">; memory management and register allocation, but we'll provide libraries to</span> +<span class="Comment">; help with them.</span> +<span class="Comment">;</span> +<span class="Comment">; The initial OS will provide just memory management and concurrency</span> +<span class="Comment">; primitives. No users or permissions (we don't live on mainframes anymore),</span> +<span class="Comment">; no kernel- vs user-mode, no virtual memory or process abstraction, all</span> +<span class="Comment">; threads sharing a single address space (use VMs for security and</span> +<span class="Comment">; sandboxing). The only use case we care about is getting a test harness to</span> +<span class="Comment">; run some code, feed it data through blocking channels, stop it and observe</span> +<span class="Comment">; its internals. The code under test is expected to cooperate in such testing,</span> +<span class="Comment">; by logging important events for the test harness to observe. (More info:</span> +<span class="Comment">; <a href="http://akkartik.name/post/tracing-tests">http://akkartik.name/post/tracing-tests</a>)</span> +<span class="Comment">;</span> +<span class="Comment">; The common thread here is elimination of abstractions, and it's not an</span> +<span class="Comment">; accident. Abstractions help insiders manage the evolution of a codebase, but</span> +<span class="Comment">; they actively hinder outsiders in understanding it from scratch. This</span> +<span class="Comment">; matters, because the funnel to turn outsiders into insiders is critical to</span> +<span class="Comment">; the long-term life of a codebase. Perhaps authors should raise their</span> +<span class="Comment">; estimation of the costs of abstraction, and go against their instincts for</span> +<span class="Comment">; introducing it. That's what I'll be trying to do: question every abstraction</span> +<span class="Comment">; before I introduce it.
