During pill and install prop generation.
In autopill, we stop tracking a copy of the blob store, instead just
having the pill lib scry it out on-demand.
Adds .snub to ames-state, a global blocklist for ships. If a packet is
received from a ship that is in the .snub set, it is immediately
dropped. Adds %snub to ames' $task, to allow manipulating this list
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).
Previously, the initial Azimuth snapshot was stored in Clay and shipped
in the pill. This causes several problems:
- It bloats the pill
- Updating the snapshot added large blobs to Clay's state. Even now
that tombstoning is possible, you don't want to have to do that
regularly.
- As a result, the snapshot was never updated.
- Even if you did tombstone those files, it could only be updated as
often as the pill
- And those updates would be sent over the network to people who didn't
need them
This moves the snapshot out of the pill and refactors Azimuth's
initialization process. On boot, when app/azimuth starts up, it first
downloads a snapshot from bootstrap.urbit.org and uses that to
initialize its state. As before, updates after this initial snapshot
come from an Ethereum node directly and are verified locally.
Relevant commands are:
- `-azimuth-snap-state %filename` creates a snapshot file
- `-azimuth-load "url"` downloads and inits from a snapshot, with url
defaulting to https://bootstrap.urbit.org/mainnet.azimuth-snapshot
- `:azimuth &azimuth-poke-data %load snap-state` takes a snap-state any
way you have it
Note the snapshot is downloaded from the same place as the pill, so this
doesn't introduce additional trust beyond what was already required.
When remote scry is released, we should consider allowing downloading
the snapshot in that way.
Previously we stored the nonce in $boat, which changed the $bowl of each
agent. This compiles and all agents reload, but more testing is needed.
It also renames inbound/outbound watches to $bitt/$boat.
This converts the blob store from having deltas, directs, and
tombstones, to just having direct pages. This simplifies a lot of code,
since we don't have to constantly ensure that deltas always have their
parent available.
This removes the hardcoded text diff logic from clay, which was
previously required for bootstrapping.
Over the wire, we handle both old and new requests and responses
transparently, so communication is normal in both directions across
ships which do or do not have this change.
