in reply to Why is there no "Download code" link next to Reply?

Now that you mention it, why not! I agree that getting the code out of a reply is messy so I often just cut and paste to an editor and then sort out the line wrapping.

I too would appreciate the ability to download cod eout of a reply whilst reading the thread.

    Eh, what? Just open the reply by itself in another browser window, or in a new tab if your browser supports it, and there there's a "download code" link.

    If you can't be bothered to go over an intermediate page, you can't go to the page with just the code, either.

      Going to the page with just code is pretty fast in PM. That makes sense since the server doesn't need to do a lot. But when it takes 30+ seconds for an intermediate page to render, I tend not to be bothering as well. Which is a shame.

      In my view, the intermediate page is waisting server resources, as it does not really bring anything new, apart from the link to the code download. If the link would be directly available, it would save on the server side as well as on the client side. And as far as I understand, no extra database access would be needed to create the link. So it would only be a little bit more CPU and some more HTML output.

      I have no idea whether the slowness of PM is caused by CPU or (database) IO starvation. If it's IO starvation, then some extra CPU would not be a problem.

      What then remains is the question whether the extra bandwidth needed for the extra HTML compares to the bandwidth saved by the extra page not having to be sent. Looking at the amount of whitespace in the HTML sent by PM, and the fact that it does not seem to support gzip encoding, leads me to conclude that the possible extra bandwidth should not be a problem either.


        The slowness of PM is caused by DB slowness. (It's IO from the point of view of the web server. I don't know if it's CPU or disk from the point of view of the DB server, so I hesitate to call it "IO" without further specificis.) And actualy,your idea would cause a check if the cached version of downloadcode is up to date for each note displayed. But that's very minor compared to the overhead of displaying a new (full) page.
