thinking about upgrades & versioning

upgrades & versioning

  • there are two rough stages of software that come to mind:
    1. given an experimental/in-dev tool, you'd want a community that cares about the tech & is sufficiently excited about it & tolerant/forgiving enough of bugginess. in this case, frequent breakages and upgrades are reasonable
    2. if a community wants a tool that "just works", a stable tool is best. a tool that's mature enough that it basically NEVER needs to be updated again after the initial install, and even if upgraded, are just bug fixes that don't break any compatibility in the data or protocol layers
  • Mapeo is in category 1, but is often being deployed in category 2 situations, which seems like a recipe for disappointment & frustration. expecting an immature tool to be a mature tool is going to be frustrating
  • ideally we'd do our best to maintain backwards compatibility, but it's worth considering how frequent breaking changes are,
  • i.e. if we release a data/proto breaking change every 3-5 months, it doesn't make

why I publish to npm + don't publish to my distro package manager

re: https://drewdevault.com/2018/01/10/Learn-your-package-manager.html

  • needs human effort to {write,modify} the package per distro, per update
    • do the write/update
    • someone working on the distro to review the work & merge it
  • need to wait until next release for people to use the package/update
    • need to maintain a private pkg server (per distro; or just fuck the others)
  • does my pkg then depend on distro pkgs or npm ones?
