@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.
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.
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.

Exposes a scry endpoint. Any requests made to the /app/scry.mark url
under the endpoint will scry into %app using a %gx scry, at the
/scry/noun path, and attempt to convert the scry result into the %mark,
before converting that into the %mime mark, and sending that as an http
response.
Associates channels with the authentication sessions that opened them,
and deletes the channel when its associated session expires.
Also updates the debug dashboard to display channel counts per session.
Set up, by default, on /~/logout.
Sending a POST request to this expires the current session and redirects
to the login page. If the "all" key is set in the request body, expires
all open sessions.
Somehow we ended up with flows which expected to awaken but did not wake
up. This was likely caused by the error in r920j OTA, urbit-os-v1.0.18.
This adds a command which ensures that every flow has an active timer.
I expect this to be needed only once, but it's a pretty general tool, so
it's worth keeping.
I've included an unused @t parameter to more easily add simple debug
commands to ames without having to add a new task
At some point this should be more properly styled similar to +by, +in,
and +to, but for now this reduces duplication and makes the ordered map
available to everyone.
Allow one or more whitespace characters before and/or after the equals sign in
name attribute pairs, such as `<hello a = "yo" />` or `<hello a= "yo" />`.
Following the spec at https://www.w3.org/TR/2006/REC-xml11-20060816/#NT-Eq.
Support /=peers= and /=peer=/~ship scries for getting at all peers and
a specific peer's connection state, respectively.
Moves some internal types into zuse for easier external use.
`at` is for when you expect an array of a certain exact structure. If it
has extra elements, that indicates you were mistaken about the strucutre,
so it should fail to match.
RFC 2396 specifies that segments must be zero or more pchars.[1] We were
deviating from this by requiring at least one pchar per segment.
With this change, we support /some//path, and no longer lose the
trailing slash in /some/path/.

-merge will replace |merge so that. Once they reach feature parity and
%info is rewritten to forward to -commit, we can rip out about half of
clay.hoon
Considering some of the options here were atoms, not cells, $% wasn't
appropriate, and led to *etyp:abi:ethereum resulting in ford %ride execution
failure. Simply using $? instead would result in a fish-loop, so here we split
the atom cases from the tagged union ones with a $@.
%park is a plumbing commit task. It guarantees completion in a single
event, so you have to do much of the work before calling it. -commit
is an example of how to do this.
When a ship breaches, we remove all messages that have yet to be
delivered to an app (eg if it's not yet started). We also add
|gall-sear to do this manually, but this shouldn't be needed in normal
operation.
Finally, to unblock ~zod and ~bus on mainnet, we sear one particular
ship automatically on loading hood. It cannot be done manually because
no userpace changes can be made until it's unblocked.
Instead of providing a (unit path), allows for (list path), which better
supports the "update to path and subpath cases".
For example, if /things wants updates about everything, and
/things/specific wants updates about the specific thing, they'll both
need to receive a %fact when the specific thing changes.
Previously, these would have been two separate moves. Now, gall handles
the multi-targeting for you.
