Compare +mute and +mule. Those pass through scry, which doesn't allow us to
catch crashes due to blocking scry. If you intercept scry, you can't preserve
the type polymorphically. By monomorphizing, we are able to do so safely.
It's common now for the last http response to have no body and just mark
the request as complete. http.c wasn't closing these connections
because h20 was busy and when it indicated it was ready we only checked
whether there was more data to send.
This also checks whether the request has been marked complete, and if so
finished the connection.
This broke when %kick was handled by resubscribing on your own ship
because it processed the %kick before the %leave. For example, `@t`404
at the dojo would put the dojo in an unworkable state.
You want the %leave to be processed first because you can't do a
"resubscribe" in response to that.
This adds syntax for running imps. For example:
-time ~s1
Runs the "time" imp with the argument ~s1. This blocks the terminal
until the imp has completed (backspace kills it, of course). You could
avoid blocking the terminal if you sacrifice the ability to use imps as
sources in more complex commands.
In keeping with this one-and-done view of imps, this also changes spider
to not use a live build of imps. This significantly reduces the amount
of uncertainty around imps -- spider will try exactly once to run your
imp, and if it fails it'll tell you. If you want to retry, that's up to
you.
Returns the target %zuse contract configuration to mainnet, and also
tweaks the 'arvo-ropsten' build to use %alef instead of %ames.
Also fixes a merge conflict artifact in nix/ops/default.nix.
