Instead of including wrapped-task as-is in most call traces, we now only
include it in traces for crashing (harden task) calls. For everything
else, we include only the tag of the resulting $task.
Closes#6444.
We were retrying failed kelvin upgrades as many times as we had apps
that needed to be suspended, because suspending an app triggers an
attempt to run the next kelvin upgrade. This suspends all those apps in
one batch move, and then tries the next kelvin upgrade only once at the
end.
Fixes#6407
Partially addresses #6285
Adds a "mode" to channels, which can be set to either %json (current
behavior) or %jam. For %jam channels, aside from the SSE framing, all
communication happens through @uw-encoded jammed nouns. This applies to
both outgoing channel events, as well as incoming channel requests.
We choose @uw-style encoding because raw bytestreams are fragile and
cannot work inside the SSE stream context.
Currently, a separate endpoint (/~/channel-jam/etc) is used to indicate
%jam as the desired mode for a channel. We will probably want to make
this a bit cleaner, not least because it's not currently implemented as
a formal standalone endpoint, but also to give it stronger aesthetic
equivalence with the existing channel endpoint. Putting the mode in the
file extension is a tempting option here, but semantically not quite
right.
Connecting to the same channel across multiple modes is currently
supported, but it's untested, and unclear whether this is desirable or
not.
Marks it as deprecated in lull with a comment, and removes the verbosity
toggle state from dill. Filtering should now happen at the edges where
%crud error messages get printed.
We don't remove it from lull just yet, because that would necessitate a
kelvin bump, even though the rest of this changeset doesn't.
previously we were acking the nack-trace message (adding a %send move)
before notifying the message-pump with a %near task. Now, due to the
refactoring we invert the order of those moves. This seems safe but will
determine with livenet testing
