  I can appreciate the honesty of that video.

    This bug (input field doesn't scroll automatically, but spills its text into the surrounding elements) is a good demonstration of just how many, many small details you have take care of when implementing a browser engine. A really monumental task. The servo devs have my respect!
    - oneeyedpigeon 11y ago
      Maybe I'm missing something hugely obvious, but shouldn't the input field be rendered using a native control which would preemptively eliminate that bug and reduce the need for rewriting code that's been written countless times before?
      - dumbmatter 11y ago
        There's probably many reasons, but one is that native controls don't support everything in CSS.
      - Manishearth 11y ago
        dumbmatter is correct, we can't arbitrarily style things via CSS with native controls. Eventually we do want them to look more like the controls on the platform they're running on, though.

Broadly speaking, native controls don't like being composited into OpenGL scenes (which are necessary for things like 3D transforms).

    Haha. Maybe related: https://github.com/servo/servo/issues/4378 https://github.com/servo/servo/issues/4378

      I wonder if anyone has thought of including screencasting in bug reporting for bugs in guis?
      - bjz_ 11y ago
        We used to use LICEcap at my old work for that.

        Wonderful, you just make aware of the software that do exactly what I need today :-)

        There's also https://github.com/thetarkus/WebMCam https://github.com/thetarkus/WebMCam which records in a more modern format than gif.

        On Windows only.

        Looks potentially better but I experience lots of crash/freeze

        For anyone wondering how to do this on linux, I use recordmydesktop and ffmpeg to make small webms (~2mb). Highly recommend it. `recordmydesktop --windowid $(xwininfo)` and click the window you want to record. `ffmpeg -i out.ogv -o final.webm` and you're done! recordmydesktop is available in most distros afaik.

You mentioned the URL-parsing macro twice. Congrats to the whole team!

(Copying my comment here from Reddit /r/rust:) Just to repeat, because this was somewhat buried in the article: Servo is now a multiprocess browser, using the gaol crate for sandboxing. This adds (a) an extra layer of defense against remote code execution vulnerabilities beyond that which the Rust safety features provide; (b) a safety net in case Servo code is tricked into performing insecure actions. There are still plenty of bugs to shake out, but this is a major milestone in the project.
