Long output makes less behave weird

[d3m1gd]

System: linux x86_64
Terminal: rxvt-unicode

if the program is run several times as ./test | less, then less itself does not react to spacebar, and on exit leaves terminal in a broken state with no echo of characters. In order to fix, command reset is needed to be input into terminal.

Tested also ./test | LESS="" less to prevent less options to interfere, and also from another user with no environmental variables set at all in a plain terminal.

Also problem is exactly reproduced in linux console (aka Ctrl+Alt+F[1-6]).

actor Main
  new create(env: Env) =>
    var i: I32 = 1
    while (i=i+1) < 100 do
      env.out.print(i.string())
    end

100 is choosed so lines dont fit on screen. If your terminal is able to show more than 100 lines, adjust accordingly.

Thanks! Should be fixed now.

Pony from HEAD still gives me the same problem. Sometimes problem is observed only on second run of ./test | less

@d3m1gd Nice catch! I had to run 3+ times to get the behaviour, but it did indeed show up. I just checked in another fix - can you please confirm it works for you, and if it does I'll close the issue?

[d3m1gd]

Everything works good now, thanks for a quick fix!

[sylvanc]

Glad to hear it! Thanks for the report!

I have reopened this issue, because now running httpget and not using less randomly truncates the output.

The fix in place for #205 seems to also fix this. I'll close this one, but leave #205 open until it is confirmed to work.
