Hood

%hood is the system manager and control agent included in the %base desk. It's divided into three modules located in /lib/hood/:

  • %drum: CLI app management. It acts as the middle-man between the Dill vane and the individual CLI apps, including the Dojo itself.

  • %helm: system control. It handles requests for things like sending |his, spawning moons, packing and melding, seting verbosity, etc. It's the middle-man between user commands and the kernel. It's the target of many of the Hood generators (those that begin with |) like |moon, |hi, |verb, etc, and the various vane-specific generators.

  • %kiln: desk updates and filesystem control. It's responsible for tracking and applying desk updates (like when you run |install ~mister-dister-dozzod-dozzod %landscape). It also exposes a number of Clay and filesystem-related actions. It's the target of a number of Hood generators (those that begin with |) like |commit, |install, |mount, |suspend, etc.

While you usually interact with Hood via its generators, its API can also be used by agents, so it's useful to know what its pokes and other endpoints are. We'll look at each module in turn.

Drum

Drum's CLI app management functionality is usally mediated but functions in the /lib/sole.hoon library. We'll not document it here. For more information on CLI apps, you can refer to the Command-Line Apps guide and Building a CLI app example.

Drum's additional API is as follows.

Scries

Our ship

A scry with a path of /x/kiln/our will return our ship as a @p with a %noun mark.

Example:

> .^(@p %gx /=hood=/kiln/our/noun)
~zod

Kernel update blocked?

A scry with a path of /x/kiln/lag will return a ? with a %loob mark specifying whether a kernel upgrade is blocked.

Example:

> .^(? %gx /=hood=/kiln/lag/loob)
%.n

Base hash

A scry with a path of /x/kiln/base-hash will return the %base base hash as a @uv with a %noun mark.

Example:

> .^(@uv %gx /=hood=/kiln/base-hash/noun)
0v1l.6h9mk.s675m.jmi9q.g5isc.20q0l.g6r86.36v92.1l6db.li3hh.6r68a

Sync source change requests

A scry with a path of /x/kiln/jumps will return the current sync source change requests as an %all $jump with a %kiln-jump mark.

Example:

> =hood -build-file %/sur/hood/hoon
> .^(jump:hood %gx /=hood=/kiln/jumps/kiln-jump)
[%all all=~]

Syncs

A scry with a path of /x/kiln/syncs will return a map from $sync-record to $sync-state of the currently active desk syncs with a %noun mark.

Example:

> =hood -build-file %/sur/hood/hoon
> .^((map sync-record:hood sync-state:hood) %gx /=hood=/kiln/syncs/noun)
[ n=[p=[syd=%landscape her=~mister-dister-dozzod-dozzod sud=%landscape] q=[nun=~.0v3 kid=~ let=0 nit=~ hav=~ yea=%.n]]
  l=~
  r=~
]

Sync sources

A scry with a path of /x/kiln/sources will return a (map desk [ship desk]) of the current syncs with %noun mark.

Example:

> .^((map desk [ship desk]) %gx /=hood=/kiln/sources/noun)
[n=[p=%landscape q=[~mister-dister-dozzod-dozzod %landscape]] l=~ r=~]

Global automerge setting

A scry with a path of /x/kiln/automerge will return a ? saying what the default automerge policy is with a %loob mark.

Example:

> .^(? %gx /=hood=/kiln/automerge/loob)
%.y

Pikes

A scry with a path of /x/kiln/pikes wil return a $pikes of the state of apps with a %kiln-pikes mark.

Example:

> =hood -build-file %/sur/hood/hoon
> .^(pikes:hood %gx /=hood=/kiln/pikes/kiln-pikes)
[ n=[p=%base q=[sync=~ hash=0v1a.kt0d8.rvtjm.fkmp2.oblo6.oq3jp.mahql.22k1d.ilrdk.rljer.ift9b zest=%live wic=~]]
    l
  [   n
    [ p=%groups
        q
      [ sync=[~ [ship=~sogryp-dister-dozzod-dozzod desk=%groups]]
        hash=0v11.p6g14.eprqt.8vfd5.j8cm8.m914c.mlqrf.fm32d.tbuds.hai44.462ag
        zest=%live
        wic=~
      ]
    ]
    l={}
    r={}
  ]
    r
........

Pending syncs

A scry with a path of /x/kiln/pending will return a %pending $sync-update for pending syncs with a %kiln-sync-update mark.

Example:

> =hood -build-file %/sur/hood/hoon
> .^(sync-update:hood %gx /=hood=/kiln/pending/kiln-sync-update)
[%pending pending={}]

Set system error verbosity

A poke with a %drum-knob mark will set the verbosity level for %crud error messages generated by the system.

Accepts

[tag=@tas lev=?(%hush %soft %loud)]

  • .tag: should always be %crud, all other tags have no effect.

  • .lev: verbosity level.

Example

> :hood &drum-knob [%crud %hush]
>=

Shut down ship

A poke with a %drum-exit mark will shut down the ship.

Accepts

~

Example

> :hood &drum-exit ~
>=

Connect CLI app

A poke with a %drum-link mark will connect the specified CLI app on the specified ship to the Dojo (you can cycle between linked CLI apps with Ctrl+X). Note you can connect to the Dojo of remote ships if they've given you permission by running :dojo|allow-remote-login ~sampel-palnet.

Accepts

[ses=@tas gyl=gill:gall]

  • .ses: terminal session. Typically %$ for the default one.

  • .gyl: the ship and app to link. A (pair ship term) where the $term is the app name.

Example

> :hood &drum-link [%$ ~sampel-palnet %dojo]
>=
drum: link [~sampel-palnet %dojo]

Disconnect CLI app

A poke with a %drum-unlink mark will unlink a previously linked CLI app.

Accepts

[ses=@ta gyl=gill:gall]

  • .ses: terminal session. Typically %$ for the default one.

  • .gyl: the ship and app to unlink. A (pair ship term) where the $term is the app name.

Example

> :hood &drum-unlink [%$ ~sampel-palnet %dojo]
>=

Write file to Unix

A poke with a %drum-put mark will write the given atom out to the Unix filesystem in <pier>/.urb/put/. It just writes the atom's bytes so is agnostic to the format. Most commonly you'd give it a $cord to write out a text file.

Accepts

[pax=path arg=$@(@ [@tas @])]

  • .pax: the path where the last element is the extension, so /foo/bar/txt is written to <pier>/.urb/put/foo/bar.txt.

  • .arg: either the atom to write or a pair of session ID and the atom to write. If no session ID is given, it'll default to the default session %$, which is typically what you want.

Example

> :hood &drum-put [/foo/bar/txt 'foo']
>=

Then in Unix:

$ cat ~/piers/zod/.urb/put/foo/bar.txt
foo

Helm

Helm provides an interface for a number of vane tasks. Some of them are generally useful and some are fairly obscure debug functionality. We will document all of them here for completeness.

Reset Ames congestion control

A poke with a %helm-ames-prod mark will reset congestion control in Ames for the specified ship(s).

Accepts

(list ship)

Example

> :hood &helm-ames-prod ~[~sampel-palnet ~sampel]
>=

Blacklist/whitelist ships in Ames

A poke with a %helm-ames-snub mark will whitelist or blacklist a list of ships in Ames. Ships on the blacklist or not on the whitelist will have all Ames traffic dropped. Note that this overrides the existing blacklist/whitelist, it's not additive.

Accepts

[form=?(%allow %deny) ships=(list ship)]

  • .form: %allow means whitelist, %deny means blacklist. A whitelist means all traffic from sources other than the ships specified will be dropped. A blacklist means traffic from the specified ships will be dropped, and other traffic will be allowed.

  • .ships: The list of ships to whitelist/blacklist.

Example

> :hood &helm-ames-snub [%deny ~sampel-palnet ~sampel ~]
>=

Filter Ames debug prints

A poke with a %helm-ames-sift mark will turn off Ames verbosity for all but the specified ships. Note this overrides existing per-ship verbosity settings. If the list is empty, it'll just turn on verbosity for all ships. This would be used in combination with %helm-ames-verb to turn on specific Ames debug prints. Without any debug prints turned on, you won't see any difference.

Accepts

(list ship)

Examples

> :hood &helm-ames-sift ~[~sampel-palnet ~sampel]
>=

Set Ames verbosity

A poke with a %helm-ames-verb mark will turn on debug prints for specified Ames debug flags. Note this will override any previous settings. An empty list of debug flags will turn off all Ames debug prints.

Accepts

veb=(list verb:ames)

See the $verb:ames entry in the Ames data types reference for details of the different verbosity flags.

Example

> :hood &helm-ames-verb ~[%snd %rcv %odd %msg %ges %for %rot]
>=

Resend timers in Ames

A poke with a %helm-ames-wake mark will tell Ames to set resend timers for any flows that lack them. This was introduced to solve a bug in an old kernel version and is unlikely to be useful.

Accepts

~

Example

> :hood &helm-ames-wake ~
>=

Close stale flows in Ames

A poke with a %helm-ames-kroc mark will close all stale Ames flows for the given list of ship-$bone pairs. If the optional .dry flag is enabled, it won't do anything. This requires a great deal of additional logic to use, and is better left to the |ames/close-flows generator.

As of the directed messaging update in [%zuse 410], Ames no-ops on the %kroc task this poke sends. Therefore, this poke is no longer useful.

Accepts

[dry=? bones=(list [ship bone])]

  • .dry: whether it's a dry run (no-op) or whether the stale flows should actually be closed.

  • .bones: the ship-$bone pairs for which stale flows should be closed.

Adjust congestion control in Ames

A poke with a %helm-ames-cong mark will adjust the congestion control constants in Ames. You shouldn't change these unless you know what you're doing.

Accepts

[msg=@ud mem=@ud]

  • .msg: number of pending messages to be considered clogged (default is 5).

  • .mem: number of pending message fragments to be considered clogged (default is 100.000).

Note that Ames .mem no longer considers .mem in its clog calculations so you should just leave it as the default 100.000.

Example

> :hood &helm-ames-cong [4 100.000]
>=

Print Atom details

A poke with a %helm-atom mark will print source, size and hash information about the given atom.

Accepts

@

Example

> :hood &helm-atom 'foo'
>=
< ~zod: atom: 3 bytes, mug ~bantep-harfyl

Automatic memory reports

A poke with a mark of %helm-automass will tell Hood to repeatedly run a memory report at the given interval. You can turn it off again with %helm-cancel-automass.

Accepts

recur=@dr

  • .recur: the memory report interval. For example, ~m1 would be every 1 minute.

Example

> :hood &helm-automass ~m1
>=

Cancel automatic memory reports

A poke with a mark of %helm-cancel-automass will turn off Automass automatic memory reports.

Accepts

~

Example

> :hood &helm-cancel-automass ~
>=

Rotate web login code

A poke with a mark of %helm-code will rotate a ship's web login code. Note all existing web login sessions with be ended, and you'll need to run +code to get the new login code. Note also that cycling the code like this means Bridge can't automatically derive the web login code.

Accepts

act=?(~ %reset)

  • .act: if it's null it's a no-op, if it's %reset it changes the code.

Example

> :hood &helm-code %reset
>=

Approve CORS origin in Eyre

A poke with a mark of %helm-cors-approve will approve the given CORS origin URL.

Accepts

=origin:eyre

  • .origin: this is a cord containing the fully qualified URL to whitelist for CORS.

Example

> :hood &helm-cors-approve 'http://localhost:8081'
>=

Deny CORS origin in Eyre

A poke with a mark of %helm-cors-reject will reject the given CORS origin URL.

Accepts

=origin:eyre

  • .origin: this is a cord containing the fully qualified URL to whitelist for CORS.

Example

> :hood &helm-cors-reject 'http://localhost:8081'
>=

Kill old-style outgoing subscriptions in Gall

A poke with a mark of %helm-doff will kill old-style outgoing subscriptions in Gall. This is an obscure bug-fixing task for old kernel versions that shouldn't be used unless you know what you're doing.

Accepts

[dude=(unit dude:gall) ship=(unit ship)]

  • .dude: agent name or null for all agents.

  • .ship: old-style outgoing subscriptions to the specified ship or null for all ships.

Example

> :hood &helm-doff [(some %foo) (some ~sampel-palnet)]
>=

Filter Gall debug prints

A poke with a mark of %helm-gall-sift will filter Gall verbosity to the specified agents. Note this overrides previous filters and simply removes all filters if the list of agents is empty.

Accepts

dudes=(list dude:gall)

Example

> :hood &helm-gall-sift [%foo %bar ~]
>=

Set Gall verbosity flags

A poke with a mark of %helm-gall-verb will enable the specified Gall verbosity flags.

Accepts

veb=(list verb:gall)

  • .veb: currently, the only $verb:gall is %odd.

Example

> :hood &helm-gall-verb ~[%odd]
>=

Kill incoming subscriptions in Gall

A poke with a mark of %helm-gall-lave will kill the specified incoming Gall subscription(s). This is for developer debugging and should not be used unless you know what you're doing.

Accepts

[dry=? subs=(list [v=?(%g %a) =ship =dude =duct])]

  • .dry: if true, no-op.

  • .subs: a list of tuples where:

    • .v: the %a option simultaneously sends the subscriber a %kick and calls the target agent's +on-leave arm as though the subscriber initiated it. The %g option just calls +on-leave without sending a %kick to the subscriber.

    • .ship: the subscriber's ship.

    • .dude: the agent, a @tas.

    • .duct: the subscription $duct.

Example

> :hood &helm-gall-lave [| [%a ~sampel-palnet %foo ~[/some/duct]]~]
>=

Print a hi

A poke with a mark of %helm-hi will print the source of the poke and the incoming message (or its hash and size if it's very large). Note this is the handler for incoming |his. To send outgoing ones, see %helm-send-hi.

Accepts

mes=@t

  • .mes: a $cord message to print or just an atom if it's longer than 100 bytes and you just want the size and hash rather than the message itself for testing.

Example

> :hood &helm-hi 'foo'
>=
< ~zod: foo

Pass notes to vanes

A poke with a mark of %helm-pans will pass the given list of $note-arvos to their respective vanes. This is like |pass but for multiple tasks.

Accepts

(list note-arvo)

Example

> :hood &helm-pans :~  [%d %flog %text "foo"]
                       [%d %flog %text "bar"]
                       [%d %flog %text "baz"]
                   ==

    tri: KB/282.232
...

Meld memory

A poke with a mark of %helm-meld will tell the runtime to deduplicate the ship's state, reducing memory usage. Note this can be memory-intensive for ships with large states.

Accepts

~

Example

> :hood &helm-meld ~
>=
~zod:dojo> atoms (234614): MB/1.048.576
cells (7639325): MB/67.108.864
serf: meld: gained: MB/60.364.648
pier: meld complete

Register new moon

A poke with a mark of %helm-moon will save the given moon's pubkey in Jael so it can be booted and communicate on the network. Note that the keys must be provided explicitly.

Accepts

sed=(unit [=ship =udiff:point:jael])

  • .sed: if null, no-op. Otherwise add the given moon with the given pubkey and life in the $udiff:point:jael to Jael. See the |moon generator's source for details of key generation.

Breach a moon

A poke with a %helm-moon-breach mark will breach the specified moon (assuming its a child of your ship), incrementing its $rift.

Accepts

ship

Example

> :hood &helm-moon-breach ~sampel-sampel-dozzod-dozzod
>=

Pack memory

A poke with a mark of %helm-pack will tell the runtime to compact memory.

Negotiate migration to directed messaging with a ship

A poke with a mark of %helm-send-ahoy will request to migrate networking with the given ship to Mesa (directed messaging).

Accepts

[her=ship test=?]

  • .her: the target ship.

  • .test: if true, it will merely test directed messaging upgrade negotiations but won't actually enable it.

Migrate to directed messaging

A poke with a mark of %helm-mass-mate will migrate networking with the target ship or all ships to Mesa (directed messaging). This is like %helm-send-ahoy except it doesn't do the negotiation part and it can do it for everyone, not just a single ship. This is dangerous and should not be touched unless you know exactly what you're doing.

Accepts

[ship=(unit ship) dry=?]

  • .ship: either a specific ship, or null for all ships.

  • .dry: if true, it does a test-run without actually applying the upgrade.

Negotiate reversal of directed messaging migration with ship

  • .test: if true, it does a dry-run of the negotiation without actually applying it.

Reverse directed messaging migration

A poke with a mark of %helm-mass-rege will reverse directed messaging migration back to ordinary Ames networking for either a specific ship or all ships. This is the same as %helm-send-rege except it doesn't do the negotiation part and it can do it for everyone, not just a single ship.

Accepts

[ship=(unit ship) dry=?]

  • .ship: the target ship, or all ships if null.

  • .dry: if true, it does a dry-run test of the reveral without actually applying it.

Serve a generator over HTTP

A poke with a mark of %helm-serve will bind a generator to a URL path in Eyre so it can be run over HTTP. Note the generator has to be structured like so:

|=  [[now=@da eny=@ bek=beak] ~ ~]
|=  [authorized=? =request:http]
^-  simple-payload:http
...

Accepts

[=binding:eyre =generator:eyre]

  • .binding: a pair of optional site and URL path. Normally the site is empty, so it's like [site=~ path=/foo/bar/baz].

  • .generator is a +trel of:

    • .desk: the desk that contains the generator.

    • .path: the path to the generator, like /gen/foo/hoon.

    • .args: any extra arguments to give the generator.

Example

In the Dojo:

> *gen/hello-world/hoon ^-  cord
  '''
  |=  [[now=@da eny=@ bek=beak] ~ ~]
  |=  [authorized=? =request:http]
  ^-  simple-payload:http
  :-  [%200 ['content-type' 'text/html']~]
  `(as-octs:mimes:html '<h1>Hello World!</h1>')
  '''
+ /~zod/base/2/gen/hello-world/hoon
> :hood &helm-serve [`/hello-world %base /gen/hello-world/hoon ~]

The in the Unix terminal:

$ curl http://localhost:8080/hello-world
<h1>Hello World!</h1>

Trim memory

A poke with a mark of %helm-trim will request vanes trim their state size at the specified priority level.

Accepts

pri=@ud

  • .pri: the larger the number, the lower the priority. Currently vanes don't consider the priority so it doesn't matter what you specify. This might change in the future.

Example

> :hood &helm-trim 10
>=
eyre: trim: closing 1 inactive channels

Toggle move trace verbosity

A poke with a mark of %helm-verb will toggle move trace verbosity.

Accepts

~

Example

Configure domain

A poke with a mark of %helm-dns-config will configure an arvo.network (or other) subdomain for the ship. The HTTP server must be bound on port 80 and be publicly available.

Accepts

[addr=(each address:dns @t) collector=dock self-check=? reset=?]

Accepts

[mon=kiln-commit auto=?]

  • .mon: a Clay mountpoint as a @tas. Typically this is just the desk name but theoretically things can be mounted with different names.

  • .auto: if false it just does a single commit and isn't actually "auto". If true it auto-commits every 1 second.

>=

Octopus merge

A poke with a mark of %kiln-fuse will perform an octopus merge of the foreign sources into the local desk with the given merge strategies. The sources can also be tracked rather than a one-off merge.

Accepts

  $@  ~
