partial revert of 3d3ea61d53, which introduced core names by completing
an unimplemented feature that was already present in hoon.hoon. we've
decided to remove this for the initial launch since it violates the
principle of least surprise for the name of a core to end up in its
$garb and yet only be used for doccords, as opposed to something like a
wing resolution. it was also confusing that this only worked for |% and
|@.
this breaks two of the tests for the dprint library, which have been
commented out. these tests ought to be restored once dprint is rewritten
in order to implement a different way to refer to cores not built by arms
this constitutes a pretty major rework of how whitespace is handled in
hoon in order to change the doccords syntax from :> and :< to ::.
in summary: throughout the hoon parser (+vast) many instances of +gap
have been replaced by +jump, which first tries to remove whitespace (+leap)
until it arrives at something that can be parsed as a prefix
doccord (+apex:docs:vast). if it does not encounter a doccord, it
instead uses +gap as normal.
if you follow along with the parser, you will notice that every time
jump is called, it then tries to call +apex:docs via +scye or +seam. if
apex:docs succeeds, it will end up consuming a newline at the end,
hiding the fact that there was valid whitespace from the parser. thus
+apex:docs then inserts a newline after successfully parsing a prefix
doccord, which will then be consumed by a subsequent invocation of +gap,
ensuring that there was proper whitespace if the doccord would have been
consumed by +gap instead of +leap.
there are a few other changes:
+hint in the compiler throws out doccords attached to %noun types. this
was already the behavior before doccords, and the change was made before
i understood what i was doing.
similarly for commenting out the %note case in +open:ap - this was an
earlier mistake
postfix comments for chapters are now enabled.
+expx was unused and removed in order to be rid of the
convention-defying +exp1. other unused +ex(p/q)* were commented out.
arms that handle batch comments (+glow and +whap) were refactored
+toad, which was used to change between tall and wide form, tries to
+jump before +gap. since +jump is ;~(pose leap:docs gap), i would have
thought that just using +jump there would be fine, but it fails for some
reason.
some parsers built with |@ were rewritten to use |*
|$ was made so that any doccords put on the spec are converted into hoon
doccords on the $ arm. it wouldn't compile otherwise. there's probably a
more principled way to do this but it works fine for now.
- fix `fragment-num` and `num-fragments` having duplicate faces
- fix faces being wrapped around wrong things in various places
- fix `bone` not being printed in "hear last in-progess" message
- make pretty tape interpolation style more uniform
in the past, +team meant "our / our moon", but
it has been primarly used to represent "our"
moons as having the full permissions of their
parents doesn't make a lot of sense anymore
this looks like the more elegant solution
instead of changing each instance of +team
I've combed through the uses of +team throughout
urbit/urbit and I'm quite sure that each instance
is better off as just "our"
The +on-cork handler asserts that the peer is known to us. This is the
incorrect behaviour, because it will crash when corking a flow to a peer
that is still an %alien. This can happen, for instance, when making a
gall subscription for the first time and then corking it before the
alien naturalises.
if a cert is configured and a secure port is live it will set the
redirect flag in http-config.state.
When it gets a ++request it will return a 301 redirect to
https://[host]/[path] if:
1. not already secure
2. redirect flag set
3. secure port live
4. is not requesting /.well-known/acme-challenge/...
5. the host is in domains.state
It will not happen if forwarded-secured, localhost, local loopback, ip
addresses or domains not in domains.state.
in ++load it checks the secure port is live and a cert is set and
enables it if so (for people who already use in-urbit letencrypt)
%rule %cert tasks also toggle it (only turning it on if secure port
live)
%live tasks also toggle it (only turning it on if cert set)
Have tested with a couple of ships and seems to work fine.
This is useful in combination with pyry's auto arvo.network dns config
system - can finally get rid of reverse proxies entirely.
Eyre always gets passed request headers in lowercase, so we should search for
the lowercased version of the header.
Arguably `+get-header` should lowercase keys before comparing them, but that's
a more serious behavioral change.
This allows you to pass a thread directly into khan, instead of passing
a filename. This has several implications:
- The friction for using threads from an app is significantly lower.
Consider:
=/ shed
=/ m (strand ,vase)
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>('hi'))
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>('there'))
(pure:m !>('product'))
[%pass /wire %arvo %k %lard %base shed]
- These threads close over their subject, so you don't need to parse
arguments out from a vase -- you can just refer to them. The produced
value must still be a vase.
++ hi-ship
|= [=ship msg1=@t msg2=@t]
=/ shed
=/ m (strand ,vase)
;< ~ bind:m (poke:strandio [ship %hood] %helm-hi !>(msg1))
;< ~ bind:m (poke:strandio [ship %hood] %helm-hi !>(msg2))
(pure:m !>('product'))
[%pass /wire %arvo %k %lard %base shed]
- Inline threads can be added to the dojo, though this PR does not add
any sugar for this.
=strandio -build-file %/lib/strandio/hoon
=sh |= message=@t
=/ m (strand:rand ,vase)
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>('hi'))
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>(message))
(pure:m !>('product'))
|pass [%k %lard %base (sh 'the message')]
Implementation notes:
- Review the commits separately: the first is small and implements the
real feature. The second moves the strand types into lull so khan can
refer to them.
- In lull, I wanted to put +rand inside +khan, but this fails to that
issue that puts the compiler in a loop. +rand depends on +gall, which
depends on +sign-arvo, which depends on +khan. If +rand is in +khan,
this spins the compiler. The usual solution is to either move
everything into the same battery (very ugly here) or break the
recursion (which we do here).
%kick is supposed to start back from the snapshot and move forward.
Without this, we would only fetch logs that we hadn't already fetched.
Thus, if you were up-to-date when you kicked, you would miss anything
that happened between the time the snapshot was taken and the present,
though you would see things after the present.
Also reverted lull change to make this a safer upgrade.
Previously, when the larva got to processing enqueued events, it was
doing so without loading state into the adult beforehand, resulting in
incorrect processing of events.
Here, we make the larva call +molt more eagerly, ensuring that the adult
always has its state available when we use it.
Yes, there is a global timer for closing flows, but all that does is
enqueue a cork message. +on-stir needs to set _pump_ timers for all
flows that might still have messages to send, which includes closing
flows.
When ames notifies us that our subscription has been kicked, we enqueue
a cork to clean up the flow. Unlike the %leave case, however, we were
not registering the cork in the queue of outstanding comms. We would
eventually get an ack, but not know what for, and erroneously inject
%poke-acks and %watch-acks.
Here we simply add a %cork entry to the queue before sending it.
This is sufficient to bring the normal (non-prerelease-bugged) cases
into the new world.
For the prerelease ships that ran a buggier version of the new gall
subscription logic, we note that the conditional may trigger for the
nonce=1 case where it had already triggered for their
(shouldn't-be-possible) nonce=0 case. This results in a %leave on a wire
that wasn't in use. This no-ops on the publisher side though, and the
flow gets corked right away, so this is considered harmless.
In response to clog notification from remote ames, we were sending a
%cork to clean up the flow. However, the wire we were using had the /sys
prefix already stripped off. Here, we put it back in.
Start by killing subscription nonce 0, then work our way up instead of
down. We enhance the printf with a "total nonces" indicator so we can
still easily see the progress being made.
Previous +ap-doff kicked the agent repeatedly. We needed to kick
it only once. Now publisher agents clear their incoming subscription
state without the subscriber making lots of new subscriptions because
of repeated kicking.
+on-plea gets called in two very different ways:
1) handling request from local vane to send %plea to peer
2) handling %cork request from another ship, which our local ames has %pass'ed
to ourselves
In the second case, we shouldn't print misleadingly, or bind a duct in the ossuary.
+ap-nuke was not including the nonce, but should.
+ap-handle-peers was potentially including a zero nonce.
(The latter shouldn't have been possible, but there's a bug in +load
where sub-nonce.yoke gets initialized as 0 instead of 1.)
Gall tells ames to %cork flows for subscriptions it has closed.
Receiving a kick also closes a subscription, but gall wasn't issuing a
%cork in that case. We correct that here.
Inlines +mo-handle-ames-response's logic at its only callsite.
seems that this structure has been unused since
e75ab631a4 and confuses
newbies trying to figure out exactly what the commit
structure is (which is how I came across this)
Without this, a ship would send a cork on a max of one flow per
recork timer, which could take years to clear for some ships.
This starts a hot loop of trying the next cork once one gets
positively acked.
The previous recork timer queued up %cork messages without sending them.
It also relied on making sure pump timers didn't get set for recork bones.
This was fragile.
The new design enqueues up to one new %cork message per ship during each
recork timer, based on the state of the flow. If the flow is closing but
there are no outstanding messages in it, then it needs to be recorked.
Flows will be recorked in ascending numerical order by bone.
The condition got butchered during refactor: instead of avoiding the creation
of pump timers during recork wake, it was setting them _exclusively_ during
recork wake.
this refactors the parser for %brcn and %brpt to separate the optional
argument(s) from the required argument(s).
also adds +blab, which allows for a minor refactor of a couple other
arms as well as being used for %brcn and %brpt
Problem:
by-channel has its own copy of server-state from line 2182. discard-channel returns an altered state, with one channel removed from the state of by-channel.
but the state of by-channel isn't changing with each iteration, so |trim is only removing one channel per invocation.
Solution:
update by-channel on each iteration.
