+riff-any is all clay requests except "backfill" requests. Change to
`$%` from `$^`, which was used to distinguish originally non-versioned
requests.
+fill is backfill requests and had no version number, so we add one.
We do not have version numbers on responses since those are implied by
the request. If someone requests at version `n` and you're at `n+1`,
you must respond in the format of `n`.
If someone requests at version `n+1` and you're at `n`, you crash;
though possibly you should be able to respond with message "I only know
up to `n`", in which case they may be able to re-request at `n`. In
either case, the version of the response is dictated by the request.

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.
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.
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%.
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%.
If the Forwarded header specifies the original connection is secure,
update the flag to reflect that, regardless of whether the connection
directly to the urbit was made securely.
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.
Because storing in reverse order means producing in reverse reverse
order.
The tests didn't catch this because they, too, were infected with the
"reverse moves" meme.
This commit adds 24bit true color capabilities to `sole-effect` for
those terminal supporting it (which most modern terminal does). It adds
a RGB type squashed into `$tint`, which will get converted to escape
sequences in `dill` for the moment.
As Urbit does not do `termcap` detection, this also does not attempt
that. But on terminals that doesn't support true color (e.g. linux
console), the color would be truncated to the nearest achievable
approximate.
In order to curb event queue growth when a client for whatever reason
isn't acking the events we send out, we implement a mechanism for
detecting such "clogging", and proactively kick subscriptions which are
adding too many events to the queue.
If the client hasn't sent an ack for ~s30, any subscription that accrues
more than 50 unacked %facts gets closed to prevent further buildup.
Upon reconnecting, the client will see %kick for the relevant
subscriptions and can open a new subscription as appropriate.
Includes a simple test for this behavior, and updates /app/dbug to be
able to display the newly tracked statistics.
By doing a %watch instead of %watch-as %json for channel subscriptions,
we can hopefully make better use of noun deduplication, when storing
events in a channel's event queue until they get acked.
Store the gall events from channel subscriptions as (vaseless) signs,
instead of serialized events. This should be smaller in memory, and
makes it more likely for noun deduplication to happen.
The cost is needing to reserialize upon channel reconnect, but this is
the less common case, and we don't expect it to be particularly slow.
In certain cases +find-merge-points was very slow. Specifically, the
`done` set was meant to avoid checking the same commit repeatedly, but
it didn't catch the case where a commit was added to the worklist that
was already in that worklist.
Secondly, the worklist was stored as a list but used as a queue, which
resulted in a lot of unnecessary welding. We change it to a qeu.

Instead of always providing a wildcard for the allowed methods and
headers, now echoes back the method and headers that the client asked
for, if any.
Fixes#3676.
Disallows registering bindings (through %connect and %serve) that would capture
traffic on paths starting with /~ (Eyre's) or /~_~ (runtime's, as of cc389c5).
Note that we don't touch +insert-binding, which is used by Eyre internally to
set up bindings in its own namespace.
Lets you check whether a specific Cookie header value string constitutes an
authenticated request.
/ex/=//=/authenticated/cookie/(scot %t 'cookie-string')
Intended for use in the runtime, for example with #3557.
Adds a cors-registry to Eyre's state that tracks allowed and rejected
origins for the purposes of CORS request handling.
For preflight requests, generates a response in-line.
For simple requests, adds CORS headers onto whatever response is given.

This was originally introduced by me in #1814 to address #1811. Eyre was not
canceling heartbeat timers on all relevant events making it easy to end
up with an infinite behn loop. This check allowed ships that entered an infinite
loop to recover, as per my comment at
https://github.com/urbit/urbit/pull/1814#discussion_r333477482. Otherwise it's
not necessary.
@t further indicates to the caller (although loosely, because auras
are loosely enforced types) that the input should not contain embedded
NUL bytes, which are not valid @t.
Separately, a minor improvement has been made to the performance of
the raw hoon by pinning the gates used in the inner loop.
Prior to this commit, there was a jet mismatch in to-wain (formerly
called lore, and still jetted under that name). 0 bytes in the middle of
a cord caused the jet to crash, whereas the hoon simply treated them as
the end of cord and truncated the output. The history of this behavior
is fraught with controversy. This commit rectifies the current mess with
the following rationale: Null bytes are valid ASCII/UTF-8, and \n\n in
the input will cause null list items in the output, so nulls are (for
the purposes of to-wain) allowed in cords. Trailing nulls cannot be
represented because of the nature of atoms, but that is outside the
scope of to-wain's concern. Therefore to-wain should simply measure the
cord and split on newlines, and do nothing fancy at all with nulls.
In addition, the hoon for to-wain was written in an inefficient style
that produced a lot of intermediate garbage atoms via rsh and cat. This
commit's implementation measures once and cuts once, so to speak, and so
avoids the intermediate garbage. Quick benchmarks suggest it is about
20x faster than the old hoon, but still orders of magnitude slower than
the jetted code. to-wain is the workhorse for the txt mark, so we should
still prefer to have a jet.
The old jet is left wired up under %lore, and should be removed when
support for the old, unupgraded zuse is no longer necessary. A new jet
with matching null handling has been wired up under the name %leer.
Well-behaved secp jets can now plausibly exit if they are given inputs
of the wrong size/range. Previously this was either not checked or the inputs
were silently truncated.
The secp core had some flaws: in particular, the logic for signing/recovery
did not match libsecbp256k1 w.r.t. the enigmatic "recid" (v) value. The jet
hints were also subtly wrong, in that the curve parameters were in a sample
(not an arm) and thus not matched by the jet matching scheme. Consequently,
the jets would be used (but incorrect) for other curve parameters.
Tests were also added to exercise the recovery id cases thoroughly.
Depending on the additions to term.c made in 467d8d239 allows dill to
forget about ansi escape codes, and pass styled text nouns straight on
to vere.
Also removes a bit of logic from drum, which assumed things about the
rendering of escape codes to adjust cursor positioning. Now it simply
states the semantic cursor position, letting the runtime deal with the
potential influence of styling.
If both sides changed a file in the same way, %mate used the version in
the mergebase, which is incorrect. This changes it to use the version
in the destination desk.
An example of this issue:

Ordinarily, eyre cleans up the relevant gall subscriptions whenever a
channel disappears. In yet unresolved erroneous behavior though, it may
leave a gall subscription open, despite wiping the channel from state.
Attempting to pass the response onto the deleted channel anyway results
in an %eyre-no-channel error later in the event. The volume of these
errors can degrade the user experience, as per #3196.
To resolve the annoyance (but not the underlying issue) we detect the
"subscription has no channel" case, and issue a %leave. Doing so
requires additional information in the wire, so we add that in,
refactoring the relevant wire building along the way.
Note that due to the wire requirements, this cannot resolve existing
cases. For that, we depend on bc929ba6d.
As part of the solution to #3196, we need to clean up any gall
subscriptions that eyre didn't properly clean up.
Since detecting that is hard, we opt to just wipe _all_ eyre-originating
subscriptions from gall. We inspect the duct, which isn't good, but it's
only just this once.
The main thing here is that we aggressively check whether we're in
ancestry of another mergebase candidate. This means we don't have to do
a 2nd pass to eliminate redundant candidates.
Change the definition of base-hash to be the mergebase of %home with the
OTA source. This means it's the most recent successfully-applied
update, which is usually the most important information.
Add sour-hash, which is the hash of the most recently *downloaded*
update, regardless of whether it applied successfuly (ie the old
base-hash).
Add a summary of the various hashes at the top of gen/trouble.
Only no-op if the incoming commit's parent is the old head of the desk.
Also move the printing near the end so we can know exactly if anything
changed.
Jael now stores a `step` that is combined with the original salt to
produce a new code. A `%step` card is used to increment that value,
and effectively resetting the keys. Because the first `step` is zero,
the first code is the same as before.
Eyre was changed to be notified with `%code-changed` so it can forget
old cookies, sessions and discard all the existing channels.
A new generator was added |code, that does both querying and
resetting the code
|code :: shows current code, step and help
|code %reset :: changes the code
The old +code generator still works correctly.

We used to not accept new indirect lanes if we already have a direct
lane. This means that if Bob, with a publicly-accessible lane, changes
lanes (eg by restarting the process and getting a new port or changing
ip addresses), tries to talk to Alice, who is behind a NAT, then Bob
will try directly but fail (because Alice is behind a NAT), so he will
route the message through her galaxy. This is good -- the message gets
to Alice. However, Alice had a direct route to Bob's old lane, so she
will try to ack on that lane, which fails. She will not time out this
lane because she doesn't know that Bob isn't getting the acks (acks
don't have their own acks).
The solution is that if Alice receives an indirect lane for Bob when she
already has a direct lane, she shouldn't ignore it. If the lane is the
same as what she has, she shouldn't change anything (in particular, she
shouldn't mark it as indirect). But if it's a new lane, she should
discard her old direct lane and use the new indirect lane.
RFC2396 defines[1] unreserved characters as alphanumerics and nine "mark"
characters. We were only parsing for four of those, leading to parsing failure
for valid URLs.

In Ford Fusion, Clay builds generators but Dojo and Eyre run them. Dojo
is already virtualized with a scry function, so +mule is fine, but Eyre
is not, so Eyre needs to use +mock and explicitly supply the scry
function. This does that. Fortunately, the produced result is simple
and easily clammable.
Fixes#3089
No longer abuse the desk field, instead making use of the path. Reject
any scries outside of the local ship, empty desk and current time as

Expose ducts only under a debug endpoint, nothing else should care about

Add scry endpoints for the very next timer (if any), and all timers up
to and including a specified timestamp.
When merging, +reachable-takos is called roughly once per merge commit
in the ancestry of the new commit. +reachable-takos was exponential in
the number of merge commits in the ancestry of the commit it's looking
at, due to mishandling of the accumulator. This makes it linear.
Of course, linear x linear is still quadratic, which is not great. I
doubt +reachable-takos can be made asymptotically better, but
+reduce-merge-points/+find-merge-points probably can. 50 merge commits
already gives about 14.000 iterations through the loop in
+reachable-takos. Another option is to try to memoize this somehow, but
a simple ~+ is insufficient since `s` is usually different.
In local tests on macOS with a -L copy of ~wicdev-wisryt, this speeds up
OTAs significantly. The majority of time was spent on this.

Adds +mure to run a trap in a separate road. This should eventually be
just a hint.
Vega was running inside a mule, but since +load was called within vega,
the new kernel was all run within the same mule, so it didn't actually
get to reclaim the space after hoon compiled.
We verified this with printfs in u3m_fall. On the test ship (from
mainnet) which had 800MB used, vega was taking interior free space from
950MB to 450 over the course of compiling hoon, then each vane would go
from about 450 to 350 and then back to 450 once it finished (which
proves they were correctly isolated). With this change, after hoon
compiles the free space goes back up to 950MB. This gives us a lot more
space to compile OTAs.
We had to slightly refactor the logic for doubly-recompiling hoon, since
+mure as written produces a ?(!! _trap), and you can't find faces in the
result of the trap. We could bake mure, but that's rather awkward. I
wonder if there's a way to fix this as a wet gate.
