When an application would send multiple facts during a single event, it
was possible for the first fact to trigger a clog, removing the
subscription and sending a quit, but then the second fact still getting
sent out at normal.
Here, we drop any facts for subscriptions we don't have registered in
state, which should only happen in the described case.
Eyre's clog logic was a tad inconsistent about "only facts" vs "not poke-acks".
This makes it consistently say "only facts" when it comes to clog-related logic.
Yes, in theory this means %watch-acks and %kicks can build up endlessly, but
those should take up negligible space compared to %facts.
Should fix any oddball cases of crashes here that #3835 didn't already catch.
Make the marks produce json arrays where the (list @c) type is used.
On the frontend, transform the semantic (character-based) cursor
position into a byte-based one, in order to ensure the cursor gets
rendered at the correct location, even if the presence of multi-byte
characters like emoji.
This was a little bit too crummy. Instead, we put in a placeholder of ~,
which should be forwards-compatible with atomic session identifiers,
where ~ identifies the default session.
Additionally touches up the herm wires/paths to stick to the above more
closely.
Listens to the default dill session and passes its %blits on to
subscribers. Passes any %belt pokes it gets into dill.
Updates webdojo to make use of it, which is the primary motivation for
herm's existence.
This lets us support the "random userspace app sending dill belts".
Ultimately, we'll want to be able to specify a session identifier
alongside the belt, instead of strictly relying on the duct.
Adds a %view task, which opens a subscription on the output sent to the
specified session. %flee closes the same.
Whenever dill sends a blit to the session, any subscribers get the
output also.
The structures here will become more reasonable once we replace ducts
with proper dill session identifiers.
People using older runtimes might not support the %klr blit. It's not
uncommon for prompts without style to get passed in as %pom though, so
here we catch that case and turn it into a %pro, which gets rendered as
a traditional %lin.
Pretty-printing is expensive, yet we do it whenever we construct the cookie
string, at least once (but usually twice) per authenticated request.
Here we call out the the specific to-tape functions we need, instead of relying
on the pretty-printer for converting... tapes to tapes, among other things.
The primary gains come from the cookie-related instances, we update the others
mostly for good style.
For the "receive request and immediately send response" case, that is processed
synchronously within eyre (ie, client sends channel ack), speeds thing up by
roughly 55%.
Instead of passing in a tape to print in case we need in, pass in a trap that
can be called to generate the tape on-demand.
Eagerly rendering printouts was costing us a lot of time when we didn't actually
need them, because the pretty-printer is slow.
Motivation for the change is performance improvements on the un-`^~`d uses of
ream. Parsing turns out to be slow, making ream slow in turn. So we construct
the hoon ast manually instead.
!, is arguably better style than ream, since it doesn't require a ^~ for static
input, and lets syntax highlighting function properly.
For the investigated case, in +get-cast's +grow flow, improves performance by
over 80%.
