`agents.conf` and `gateway.htpasswd` move from /var/lib/hyperhive/gateway
to /var/lib/hive-gateway/conf, alongside the `tls/` the gateway already
kept there.
nginx reads both as an unprivileged user. Under c0re's state dir it could
only reach them by traversing a directory systemd re-declares `0750
hive-core` on every c0re start — so nginx was given `SupplementaryGroups
= [ "hive-core" ]`, which also handed it read access to everything else
group-readable in that tree. The tokens are individually 0600, but the
broker sqlite carries no explicit mode: every message between every agent
was readable by the process whose job is parsing untrusted network input.
Moving the files removes the need and the exposure together. The group is
gone, and its absence is now commented as load-bearing so it doesn't come
back as a fix for a symptom it would recreate.
Also drops this module's `/var/lib/hyperhive` tmpfiles rule. It declared
`0755 root root` and could never win against `StateDirectoryMode`, and a
losing declaration still reads as a guarantee — that is what sent the
first diagnosis of the outage looking for who had changed the mode.
Ordering is unchanged and still the thing that makes a fresh boot work:
tmpfiles runs before services and seeds both files empty-but-valid, nginx
names them (an `include` of a missing file is fatal, not empty), and
content arrives when c0re writes and reloads — which it does on every
topology change, so a boot against the empty seed resolves itself.
Folds in the mode fix: `write` now sets 0644 on the tmp file before the
rename, because a rename carries the source's mode and discards the
destination's, and the tmpfiles rule that declares 0644 is
create-if-absent so it never re-applies.
Per review: docs represent current state. Every "used to" / "no longer"
clause this branch introduced is gone — including the History section in
network.md, which was a whole subsection about a sync mechanism that
doesn't exist.
Where the removed clause was carrying a real constraint, the constraint
stays and is stated in the present tense instead of as a delta: nothing
narrows what the gateway's nginx can reach except the directory
permissions in front of a socket, and nothing bounds `ReloadGatewayNginx`
except the hard-coded unit name. Those read as rules now rather than as
the story of how they came to be rules.
The gateway's nginx + dnsmasq no longer run in their own nspawn container.
`nix/host-modules/hive-gateway/default.nix` loses the
`containers.hive-gateway` wrapper and everything that existed only to punch
holes in it: `privateNetwork = false`, `CAP_NET_ADMIN`, five bind mounts,
its own `stateVersion`, `networking.firewall.enable = false`,
`networking.resolvconf.enable = false`, and the `hive-gateway-resolv`
path+service pair. 465 -> 303 lines.
The container never bought isolation here. It shared the host netns by
necessity — nginx binds the host's :80/:443, dnsmasq answers on the bridge —
so each of those settings was undoing a boundary the gateway could not
afford in the first place.
Four things made it more than a deletion, none of them visible in the nix
diff:
- The self-signed cert service also imports the hive CA leaf, so removing it
with the container would have left nginx naming a missing cert file, which
it refuses to load at all.
- The nginx reload is a hive-priv verb. It still needs root, but no longer
for the reason its doc gave, and `--machine=` was both transport and
scope — so the unit name is now hard-coded in the helper as the
containment.
- The lifecycle verb named a container that stops existing.
- `journalctl -M hive-gateway` had no machine to enter.
Per the operator's ruling, the operator verb keeps working and agents lose
it. `InfraContainer` answered three questions that used to share an answer;
it now splits into `name()` (identity), `target()` (Container vs HostUnit),
`service_unit()` (the systemd unit), and `agent_restartable()`, which the
MCP restart path checks before the capability so the refusal cannot read as
"ask for infra_admin". `SIBLING_CONTAINERS` drops the gateway — it gates the
requests that name a container as a string — while `FromStr` still accepts
it, because that answers what a name is, not who may act on it. The
dashboard's gateway journal reads host journald filtered to `nginx.service`.
Prose was corrected where it only named a location, and re-argued where the
container was doing security work: a `0666` per-agent socket was safe
because only the gateway container had the directory bind-mounted. There is
no mount now, so the directory permissions are the whole of the access
control — the constraint holds, its mechanism doesn't.
Gate: nix fmt / clippy --all-targets -D warnings / cargo test all clean (710
tests); hivectl-cli.md regenerated from the clap tree. The nix eval was run
in both TLS shapes at this commit: every delta in the rendered
virtualHosts is one of the three intended path moves, dnsmasq settings are
byte-identical, and the absence probe flips true -> false with bindMounts
emptied.
is_running collapsed every non-active state into false, so a container that
exhausted its bounded restarts read as plain "down" -- indistinguishable
from one an operator stopped deliberately. Bounding the restarts made that
gap sharper: a slow-failing agent used to grind on visibly, now it can stop
quietly.
Adds UnitState + unit_state() beside is_running rather than widening it.
is_running has ~8 call sites and nearly all are reconcile/power logic asking
"is it up? if not, start it" -- a question with two answers. Only the view
builder needs more, and it gets both facts from one systemctl call, since
is-active prints the state when not passed --quiet.
Surfaces as a flat failed flag on ContainerView and AgentStatusRow, matching
the shape those types already document: independent, orthogonally-observed
facts rather than a state machine. serde(default) keeps it order-independent
with the frontend half.
No behaviour change: nothing acts on the flag, per the ruling.
Closes the #3110 split — lib.rs is now just the crate doc comment and
the pub mod list.
journal.rs's new doc comment fixes a pre-existing bug: the old
JournalPriority doc text in lib.rs was actually half Capability's doc
(a leftover from an earlier reorder that moved the code but not the
comment above it).
GET /api/jobq/graph gains a states query param (comma-separated
hive_jobq::State names): narrows the served root groups to the named
states, keeping a group whole (filtering by a root's own state, which
is already its subtree's rolled-up answer). Absent, empty, or fully
unrecognised is the identity filter, matching prior behaviour.
hive-jobq-graph.js gains a row of per-state checkboxes above the tree,
re-fetching the endpoint with the selection on toggle. Default
selection hides Done and Skipped.
Server-side filtering (not client-side hiding) so hive-jobq-graph-update's
node list, and everything downstream of it in builds.js (count pill,
live-log panel), only ever sees what's actually shown.
hive_sh4re::assets::branding_svg() resolved a server-side default
icon at runtime from HIVE_ASSETS_DIR — the only consumer was
serve_icon(), which fell back to it whenever the agent had no
`hyperhive.icon` override. Removed both the fallback and the
function: serve_icon() now 404s when /etc/hyperhive/icon.svg is
absent, and the per-agent web UI (app.js) picks up the existing
dashboard swarm.js pattern — swap the <img> src to the
frontend-bundled /favicon.svg on load failure, guarded against
looping if the fallback itself 404s.
Updated the doc/comment claims that said the server always returns
an image (docs/web-ui/agent.md, nix/agent-modules/default.nix, the
hive-c0re/forge/users.rs comment referencing the old shared-asset
set). forge-avatar-sync and the matrix avatar sync are unaffected —
both are gated on hyperhive.icon != null and never depended on the
removed fallback.
bind_child_agent_dirs looped over state, harness and config alike and
mounted all three read-write, while the doc comment above it defended
only state. The rationale covered one dir, the loop covered three — the
uniformity is what erased the fact that the three have three different
answers.
harness holds the child's own runtime material (bash-tasks, the
turn-stats and event sqlite dbs) and nothing argues for a parent
touching it. The only other reader is stats::hive_stats, which reads the
host path directly and needs no mount into anyone.
config stays read-write here on purpose. The ruling is that it becomes
read-only, but request_init_config still has the manager seed a new
child's config in place, so flipping the mount before relocating that
step breaks agent creation hive-wide. That ordering now lives in the doc
comment, where someone about to finish the job in one line will see it.
docs/persistence.md justified all three dirs as RW; it now states the
boundary as three answers and names the right source file.
core_avatar_png() and config_org_avatar_png() were hive-sh4re
functions used only by hive-c0re::forge::users. Move them there as
private path-resolution helpers (core_avatar_png_path,
config_org_avatar_png_path), following the existing
std::env::var(...).expect(...) required-env-var style used elsewhere
in hive-c0re.
The org avatar is now independently configurable:
services.hyperhive.c0re.orgAvatarPng (nullable path, default null)
lets an operator override just the agent-configs org avatar PNG
without replacing the whole assets package. Wired via a new
HIVE_ORG_AVATAR_PNG env var that falls back to the bundled PNG when
the option is unset. The core avatar stays under HIVE_ASSETS_DIR,
unchanged.
argus's review note: current_room_state collapsed absent-state,
transport failure and an unparseable body into one None, so a
systematically failing GET was unobservable.
Only one of the three actually hides. A transport error takes the PUT
down with it one line later, and a 404 is the expected first-setup
case — both stay at debug. A non-404 HTTP failure is the silent one:
the read is broken while the write still succeeds, so the guard
switches off and the sweep resumes emitting with nothing to show for
it. That case, and only that case, warns.
Keeping the warn narrow is the point: one that also fired on every
expected 404 would train the reader to skip the line.
set_room_state PUT unconditionally and its doc called that idempotent.
It is, one level too high: a PUT of identical content is a no-op on the
room's STATE and the homeserver still appends an event to the TIMELINE.
Downstream an event is unread activity, then a todo, then a turn — for
every agent in the room. The provisioning sweep re-wiring the hive
Space's child link therefore woke the whole hive on the sweep's cadence,
forever, for a link that never changed (~1801s between events, measured
across eleven consecutive intervals).
Read the current content first and return early when it matches. The
lookup fails open — an unreadable state means write, because the
re-apply exists to repair a missing link and "don't know" must not be
treated as "fine". Only the steady state goes quiet.
One attrset describing every hive in the swarm including this one,
identical on every host, with hiveName selecting which entry is us.
"My peers" is derived (swarm.peerHives) rather than declared.
Every field in the old per-host peer list was intrinsic to the hive it
described, never to the pair -- so the list was a directory each host
kept its own copy of. Beyond the deduplication it removes a bug class:
two hosts could hold different endpoints for the same third hive with
nothing to detect the disagreement.
Drops the per-hive caCert. Trust inside a swarm derives from the swarm
root, which every hive chains to. What that genuinely removes is
trusting a hive whose root this swarm does not own -- a cross-swarm
problem that wants a mechanism of its own, not a field that happened to
work.
The matrix container's certificateFiles block goes with it and could
NOT be migrated: that list is read at build time and the swarm root is
a runtime file (its key must never enter the store), so there is no
build-time name to put there. caCert being a nix path was precisely
what made it the build-time distribution channel. Agents are unaffected
-- hive-tls folds the root into the hive trust bundle and the meta
renderer embeds that one file. Tracked separately.
Migration is an assertion plus warnings, not a rename: hives is peers
union {self}, and the set gains a member no existing config has written
down. A rename migrates a name and a default can re-root a meaning;
neither can conjure a new member. The warning explains, the self-entry
assertion stops the build.
Cross-hive trust was O(n²) hand-pinning: every hive had to name every
peer's CA. A swarm root makes it O(1) — trust the root once and every
present and future peer validates.
The root is generated by a new `swarm-ca` unit on a single-host swarm
and operator-provided otherwise; `swarm.ca.autoConfigure` picks between
them and derives its default from `swarm.peers` being empty, so "all on
one host" is read off the deployment rather than remembered. Both modes
produce the same artifacts in the same places, so splitting hosts later
is moving the service dirs, not switching code paths. The root key never
enters the nix store, and the root is never regenerated automatically —
replacing it invalidates every peer at once.
Each hive CA carries `nameConstraints` pinned to that hive's domain, so
a leaked hive CA can only mint names inside its own subdomain, enforced
by verifiers rather than by convention.
`ca.pem` was serving as both the issuer and the anchor consumers trust;
those are the same file only while it is self-signed. openssl will not
terminate a chain at a trusted cert that isn't self-signed (rustls and
Go will), so the promotion would have broken some consumers and not
others. `hive-tls-ca` now also writes `trust-bundle.pem` — the hive CA
plus whatever it is rooted at — and every anchor consumer reads that:
agents, the CI and forge containers, and the peer-config recipe. On a
hive with no swarm root the bundle is just that CA, so nothing consuming
it needs a mode to branch on.
Every prose and error-message reference to the moved options, including
two in hive-c0re/src/matrix.rs that omitted the services. prefix and so
read as the per-agent option. An error that names an option the operator
cannot find is worse than no hint.
Two sites spelled it as a brace group, services.hyperhive.{hiveName,
swarmName}, which no anchored rewrite can handle correctly now that only
one of the two moves; both are written out separately. One of them is an
MCP tool description, so it is rendered into every agent's system prompt.
Seven places described an authoring flow that does not exist: the
manager editing and committing a child's config in the bind-mounted
config dir. mara, on the snapshot issue: "the pr workflow is the main
one, anything else is legacy … the config dir in agent container is
read only copy to see own config … changes need to go through local
clone and via forge".
Two of the seven are the request_init_config MCP tool description and
its args struct, which are rendered into the system prompt of every
agent holding the approvals tool group. A wrong tool description is not
a stale comment; it is an instruction the whole hive reads as fact,
which is why the claim kept being repeated back.
The init tool creates the repo and seeds it. Nothing else. Tailoring
the seeded template is not a separate mechanism - it is the ordinary
config-change flow, a PR reviewed like any other.
Prose only; the code already implements the PR flow (an approval's
commit_ref is a PR number). Where a doc justified the parent's
read-write mount on the child's config dir with the authoring model,
the justification is removed rather than replaced: that mount is a
defect tracked on its own issue, and it should not read as intentional
while it waits.
The last of the DAG-container removal. `tests.rs` navigated by the id
`submit` returned, so removing the container removed the tests' way of
finding what they inserted; they name the roots they assert on now, which
is the same handle production uses.
Three findings the port surfaced, each a behaviour change rather than a
test fix:
- Cancelling a rebuild's head no longer drops the job. `Reconcile`'s edge
accepts a skipped brace, and a cancel-cascade skips rather than cancels,
so the tail stays claimable. Dropping a job means cancelling every id the
insert returned.
- A directly-cancelled group root reads terminal while a spared tail still
runs; the cancel used to land on a node above it, which rolled up
Finishing instead.
- "One DAG per hive-wide op" is not expressible without a container. The
three tests asserting it now assert that every named root is top-level,
which is what makes the per-agent subgraphs concurrent.
Deletes two tests: one asserted only that two containers get distinct ids,
the other re-ran an existing case under a second name.
`Source`, `insert_group` and the stop path's `reason` string went dead with
the container and are removed with it.
The variant, its label, its agent-accessor arm and its no-op executor arm are
gone, along with the module prose describing a job as "a single container node
whose subtree is the work". A job is now just its nodes: a template declares
them and names the roots it wants back.
`dag_of` becomes `root_of`. It always wrapped the graph's `root_of` and still
returns the same thing, but the old name asserted a concept that no longer
exists — with no container, the parent chain ends at whichever root the template
declared, so the honest question is "which root owns this node", not "which DAG
is this in".
One comment kept its old wording on purpose: `visible_roots` explains that the
projection it replaced keyed on the container kind rather than selecting
structurally. That is a statement about the past and stays true; it now says
"the since-removed container kind" rather than naming a type that is not there
to look up.
`server.rs`'s five sites move to `power::{stop,start,restart}_many` and direct
template inserts. `submit_single` routes through the `*_many` builders with a
one-element slice rather than keeping a parallel single-target shape.
`templates::rebuild` and `templates::reparent` now return the guids of the roots
they declare, so a caller that has to wait on them can name them; previously
only the void-returning form existed and every caller got an empty id list.
Two comments corrected while converting, both contradicted by the code they sit
above:
* `templates::rebuild` said its tail is edged onto "(MetaSync, Prebuild,
Reconcile)" and that "Prebuild's roll-up carries the subtree" — the brace has
been the middle root since the AgentWindow change.
* the restart handler described the per-agent shape as starting with SetWanted,
while `restart_chain`'s own doc says a restart never rewrites `wanted` — that
is the difference between restart and stop/start.
Error handling is no longer swallowed: a failed insert becomes a reported error
rather than a silently-absent id.
The `*_many` entry points returned `insert_job`'s result while their closures
ended in `Vec::new()` — naming nothing, so the returned id list was always
empty. `queued_dags` would have shipped `Some([])` and hivectl's wait loop would
have had nothing to poll. Silent: it compiles, the op still runs, and no test in
isolation looks.
Each `*_chain` now returns its group root's guid and the `*_nodes` collectors
gather them, so the ids a caller gets back are the roots it can actually wait on.
`start_chain` returns *four* in the stale branch, not one: `rebuild_nodes`
chains its roots behind `SetWanted` with `after_ok` rather than nesting them
under it, so `SetWanted` rolls up only itself. Naming it alone would have
reported the start complete while the rebuild was still running — the same
under-reporting bug one level down.
The helpers keep shrinking the same way: resolve_id goes, 'n.id != root'
goes (the container was the only non-work node), root_of goes, and the
container-parent normalisation goes because a group root now genuinely
has parent = None. pending_kinds_filtered drops from a four-clause
multi-line filter to one line.
Also removed a doc block my earlier edit had orphaned above the renamed
helper, and swept 'under `dag`' / '`submit` returns' out of the prose.
state_of stays untouched: it reads a roll-up, which is the same question
as hivectl's queued_dags.
submit() -> insert() in tests, and the two shape walkers lose their dag
param: with no container there is no per-DAG root to filter on, nothing
to exclude (every node is real work now), and a group root genuinely has
parent = None, so the container-parent normalisation goes too. Each test
builds a fresh JobQueue, so "the DAG" is "the graph".
20 errors remain, all in tests.rs, and they are the point: changing the
helper's type from u64 to () made every site that consumed the container
id light up as `expected u64, found ()`. A type error is an exhaustive
grep -- ten helpers take a dag id, not the three I had measured.
state_of(q, dag_id) is not mechanical: it read the DAG's ROLLED-UP state,
which was the container node's own. That makes it the second consumer of
the container-as-roll-up-point, alongside hivectl's queued_dags poll.
Both want the same answer, so it waits on the same ruling.
21 of 28 non-test call sites now insert directly. power.rs compiles.
The only remaining errors are server.rs's 5, which are blocked: those
sites feed the returned id into HostResponse::queued -> `queued_dags`,
a wire field hivectl polls via QueueDag. Removing the container without
answering that breaks hivectl's wait/progress loop; asked on the issue.
Also swept the deleted symbol out of prose, not just code:
- docs/coordinator.md: "the submit layer (job_queue/submit.rs)" ->
the power layer (job_queue/power.rs), and "submits" -> "inserts".
- templates.rs module doc: points at super::power for the power ops.
- lifecycle_ops.rs module doc: says which path each op takes now.
- mod.rs's insert_group comment restated the open issue verbatim
("a DAG is addressed by its container node, which submit inserts
itself"). Replaced with what is actually true for that path.
Dashboard behaviour deltas worth review: insert failures are now
logged per agent instead of swallowed, and UPDATE-ALL emits one queue
snapshot after the loop rather than one per agent.
TREE IS RED ON PURPOSE — there is no compiling intermediate between
deleting submit and converting every caller. Checkpoint commit so the
work is durable; do not "fix" it by restoring submit.
Done:
- JobQueue::submit -> JobQueue::insert (no source/reason/container;
returns the ids insert_job names).
- submit.rs deleted. Its 6 pure chain builders + 3 async *_many
gatherers were NOT wrapper code and are rescued into
job_queue/power.rs (templates.rs documents power ops as living
outside it, because their shape needs a live is_running read).
- Converted: meta_inputs 1, topology 2, permissions 3, auto_update 2,
actions 3, lifecycle_handlers 3.
- Dropped source/reason at every converted site: nothing ever read
NodeKind::Dag's fields (only `{ .. }` matches exist), so they are
write-only. Dead reason-only locals deleted; the boot sweep's summary
became a tracing::info! rather than being lost.
Remaining: dashboard/lifecycle_ops 7, server.rs 7, and the test suite —
tests.rs has its own submit() helper whose u64 return is used as the
handle to navigate the inserted DAG, so those need a different way to
find nodes, not a mechanical port.
Measured after mara's "2/3 of this is docs, most of it duplicated": 243 of 380
added .rs lines were comments. The brace rationale was written out in full in
`model.rs`, the `templates.rs` module header, `quiesce`, `rebuild_subtree` and
`docs/coordinator.md` — five copies of one argument, which is why four docs
needed correcting earlier in this branch. Correcting every copy preserves the
thing that made them go stale.
`docs/coordinator.md` (_Braces_) is now the single home. The rest state what a
node *is* and point there. Also drops the per-operation DAG diagram from the
`templates.rs` header, which the same doc already carries, and cuts
`rebuild_subtree`'s node-by-node walkthrough down to the three choices a reader
would otherwise undo — the code below it is the source of truth for the shape.
Comments -59 lines, no behaviour change, 317 tests unchanged.
The `Signal` -> `Drain` pair was built in three places, in three different
shapes: siblings under `SetWanted` in `stop_chain`, `Drain` nested under a
lease-holding `Signal` in `restart_chain`, and — as of this branch — a hybrid in
`rebuild_subtree` that was brace-held like the first and nested like the second.
`templates::quiesce(builder, agent, brace)` is now the one definition, returning
the `Drain` handle a caller edges its stop onto. Both nodes hang off the brace as
dep-ordered siblings and declare nothing, borrowing the lease it already holds.
That also fixes an inconsistency this branch introduced: the PR argued that a
brace makes nesting unnecessary and used it to flatten `StopForUpdate` off
`Signal`, then left `Drain` nested under `Signal` two lines away. Nesting is only
load-bearing where `Signal` is itself the lease holder.
`stop_chain`'s pair loses its own `Agent` declaration as a result — `SetWanted`
holds the lease for the subtree, so those were redundant re-entrant borrows.
`restart_chain` is left alone and says why in place: it has no brace, so `Signal`
holds the lease and the nesting under it is what keeps the grant continuous.
Giving it one would unify all three sites at the cost of an extra no-op node on
every graceful restart, which an operator would see — not something to change as
a side effect of a rebuild-shape PR.
The pre-push comment-block lint rejected two 40-line doc blocks, correctly: the
module doc and `rebuild_subtree`'s now carry the trigger and a pointer, and the
reasoning lives in a new `#### Braces` section.
That move surfaced a third doc the resource change had falsified. The scheduler's
lease-acquirer list still named `StopForUpdate` / `Swap` / `Signal` / `Drain`,
all of which are now exempt. The list now separates container-affecting nodes
from braces, and says why the rebuild subtree's members are exempt for a
different reason than `MetaSync` / `Prebuild`: they do touch the container, but
their brace holds the lease above them.
It reads as a swap thing but is post-*rebuild* bookkeeping: rev marker, forge and
matrix sync, manager kick, container rescan, meta-inputs snapshot. Wire label
follows (`post_swap` -> `rebuild_bookkeeping`); the graph view renders whatever
label it is sent, so nothing keys on the old string.
Also corrects a doc the previous commit falsified: this node's comment still said
it declares the agent lease as a re-entrant borrow, after that declaration moved
to the brace. Clippy and the whole suite pass over a stale doc comment, so it
took reading the file to find.
Verified by grepping the new name for places it has no business being, which
caught the sed rewriting a *historical* test name in a `// Replaces ...` comment
- reverted, since prose about the past must keep its old spelling.
The graceful path hung `Signal` under `Prebuild`, and a child only starts once
its parent's own logic completes — so the drain window waited for the entire nix
build before the agent was even asked to checkpoint. Up to the full
GRACEFUL_STOP_TIMEOUT hidden behind the build, per agent, on every boot sweep.
`Prebuild` needs the build slot and `Signal`/`Drain` need the agent lease, so
there was never any contention to justify the nesting.
Adds `NodeKind::AgentWindow`, a pure resource holder in the `DeployWindow`
pattern. It declares the build slot and the agent lease atomically and holds
both for its whole subtree; `Prebuild` and the quiesce chain hang off it as
siblings and run concurrently. `StopForUpdate` is AfterOk *both*, so the
container still goes down only once the build is ready and the agent has
checkpointed — running the drain early is the win, stopping early would just be
downtime.
Two things this deliberately reverses, both documented in place:
* The coordinated children now declare no resources. `templates.rs`'s module doc
said each node must declare its own, precisely so one running under a holding
ancestor could not get away with declaring nothing. That rule stands; the
brace is named as its one exception, because declaring a resource means "I
need this exclusively" and the lease is single-unit — two siblings that both
declared it could never overlap, which is the whole point of the shape.
* `rebuild_chain_declares_the_slot_where_the_nix_work_is` asserted the old
principle in its name. Renamed to `..._declares_its_resources_on_the_brace`
rather than left saying something the code no longer does.
Hoisting the build slot is not new serialisation: a unit is held until the
acquirer's subtree settles, and everything downstream already sat inside
`Prebuild`, so the slot already spanned the entire rebuild.
`graceful_rebuild_chain_drains_before_stopping` now asserts full rows instead of
the kind list — the kind list is identical whether the chain runs beside the
build or under it, so it could not see this bug. Verified by mutation: re-nesting
`Signal` under `Prebuild` fails exactly that one test out of 317.
/run/hive-agent/<name> was 0777 root root in steady state, not just during
first spawn. A directory without the sticky bit lets any user unlink files
in it, and the gateway container has all of /run/hive-agent bind-mounted
in, so anything that could reach the path could delete an agent's
agent.sock, bind its own, and receive that agent's todos from hive-c0re.
Two mechanisms were writing the dir and undoing each other: the tmpfiles.d
entry wrote 0777 root root, then hive-c0re round-tripped through hive-priv's
ChownSocketDir to narrow it. `d` re-asserts mode and owner on every apply
and the file is regenerated on any agent's spawn or destroy, so every such
event reset every agent's dir back to world-writable.
SyncAgentTmpfiles now carries each agent's container uid/gid and the entry
declares the answer: 0751 <uid> <gid>. Three principals need the dir and no
two share a group -- the harness binds its sockets (owner rwx), hive-c0re
dials agent.sock and the gateway's nginx dials web.sock (both only need
traverse, and both sockets are already 0666).
Deletes ChownSocketDir and ChmodSocketDir, both priv_client wrappers, the
either/or in host_config with its two swallowed warn!s, and the now-dead
socket_dir_path -- two verbs off the privileged helper's surface and one
round-trip off every agent spawn.
Also makes the two tmpfiles rules for /run/hive-agent itself agree: the
gateway module said hive-core, the generated file said root, and which won
depended on the order systemd read them in.
The deletion PR removed the types but left ~10 sites still describing
them. Two are real breakage rather than staleness: rustdoc intra-doc
links to deleted items ([NodeView::kind] and [Self::snapshot] in
job_queue/mod.rs). Neither clippy --all-targets -D warnings nor cargo
test resolves intra-doc links, so the tree was green with both already
dangling.
The rest reassert facts the deletion made false: docs/coordinator.md
documented the event as RebuildQueueChanged { seq, queue: [DagView...] }
with a per-node field list, and three sites pointed at the removed
/api/state.rebuild_queue endpoint.
One is pointer rot rather than a rename, and no grep for a deleted name
finds it: SchedulesChanged justified itself as "same snapshot-shape
rationale as RebuildQueueChanged" -- which the deletion turned into the
one event that is not a snapshot. Repointed at TombstonesChanged /
MetaInputsChanged, in both the Rust doc and the dashboard doc.
Two are pre-existing and strictly out of scope, swept under the
pfadfinderregel because the same grep surfaced them: hive-sh4re/README
advertised a jobs module that crate has not had since the host-sock
split, and hive-host-sock/README claimed its own payload types live in
hive-sh4re.
Docs and comments only -- no behaviour, no API, no test changes.
Two views of the same graph existed: the typed `DagView`/`NodeView`
(`/api/state.rebuild_queue`, the `QueueDag` socket request, and the
`RebuildQueueChanged` payload) and `hive-jobq-wire`'s generic
`GraphNode` (`/api/jobq/graph`, `QueueNodes`). Every consumer has moved
to the generic one, so the typed pair is deleted rather than kept in
agreement with it.
What that removes, beyond the types: the `QueueDag` request and
`HostResponse::dags`; `Queue::snapshot`; `dag_view`, `visible_dags`,
`shown_on_wire`, `dag_finished_at` and `containers`; and the
`rebuild_queue` field on `/api/state`. `RebuildQueueChanged` keeps its
seq and loses its payload — nothing read it, and shipping the graph
both on an event and on an endpoint is the duplication this issue is
about. It stays an event rather than becoming a poll because
push-on-change is what every other live surface here does.
Two behaviours came out simpler for a structural reason. `await_dags`
needed two rules — settled means "gone from the snapshot" *or* "present
with every node terminal" — because the typed view evicted finished
groups; the generic view doesn't, so pending is just "some node isn't
terminal". And `state_of` in the tests no longer derives a roll-up at
all: a group root's own state is the scheduler's answer.
That second one found a bug. `cancelled_dag_still_runs_its_approval
tail` asserted the group reads `Cancelled` while the tail it exists to
protect was still pending — `rollup_state` flattened the surviving
child away and called the group settled. The root reads `Finishing`,
which is what the scheduler documents: own logic done, children still
running. The test now asserts that, with the reasoning inline so it
doesn't get "fixed" back.
Kept: `Source`, `State`, `PermPayload` and the `NodeId` alias in
`hive-host-sock::jobs` — shared vocabulary, still used by hivectl.
A consumer that wants "how much is in flight" — a summary line, a badge,
a health check — had to fetch the whole graph and tally it client-side,
on every poll, in every consumer.
`hive_jobq_wire::state_rollup` counts `roots` and their subtrees by
state, straight off a `Graph<N, R>` with **no bound on either
parameter**. A node's state is a scheduler concept, so counting by state
needs to know nothing about what the payload or the resource are;
bounding it like the projection does would make a host implement two
display traits to be allowed to count, which is a requirement about
rendering imposed on arithmetic.
It takes the roots for the same reason `wire_snapshot` does — which
groups are in view is the host's policy, and nothing is ever removed
from a graph — so passing the same set makes the roll-up describe
exactly the graph beside it.
Each entry carries BOTH counts: `nodes` (the whole subtree) and `roots`
(just the group tops). One rebuild is ~7 nodes and 1 root, so a summary
meaning *operations* and one meaning *steps* are different numbers over
the same queue, and picking one here would make this crate decide what
counts as a job — the domain question it exists not to answer. It
reports both structural facts; the viewer chooses.
A pair, not a map: JSON object keys are strings, so a map would spell
the state twice and give the wire no ordering. Every state rides with
its zeros in a fixed order, so a consumer can index positionally and
never handles a missing bucket. Tallying positionally against
`ALL_STATES` means a new upstream `State` fails the exhaustive match in
`state_index` rather than silently landing in an existing bucket.
hive-c0re serves it at `GET /api/jobq/rollup`. The queue-side method is
a call site, not an implementation: it supplies the lock and the same
`visible_roots` as `graph_snapshot`, so the summary cannot describe a
different visible set than the graph it summarises.
`MATRIX_HTTP` was `http://localhost:8008`, compiled in, used at 18 call
sites. That address is right only while the homeserver happens to share
this daemon's netns, and its doc comment asserted exactly that as a
general fact. A hive whose homeserver lives anywhere else builds fine
and then talks to the wrong machine.
It now reads `HIVE_MATRIX_API_URL`, which `hive-c0re.nix` sets from
`hyperhive.matrix.apiUrl`. The matrix module fills that in with its own
loopback listener when it is the thing running tuwunel — there it is not
a guess but a fact about what it just started — and the operator sets it
by hand otherwise. There is no compiled-in fallback, for the same reason
`forge_http_base()` has none.
`is_present()` follows. It used to scan `nixos-container list` for
`hive-matrix`, which answers "is the homeserver a container on this
host" — a different question, and the reason a remote homeserver would
silently no-op no matter how it was addressed. It now asks whether a URL
is configured. A co-located hive is unaffected: the module supplies the
loopback URL whenever it runs tuwunel itself. It also stops being
`async`, since it no longer does IO, and `require_matrix_present`'s
message names both ways to have a homeserver rather than only the local
container.
Absent a URL, every matrix path no-ops exactly as it did with no
container, and the two accessors make that structural: `Option` for the
callers that fall back to `None`, a `Result` flavour naming the skipped
`is_present()` gate for the ones that propagate.
Third and last of #2860's agent-facing URL fallbacks. The operator's
ruling was "any special casing is done on the nix side - same binaries,
no hard coded fallback", so the default is deleted rather than replaced.
Every layer guessed the same wrong thing, and each guess was only ever
correct for a process sharing the host netns:
- nix/agent-modules/matrix.nix: matrixUrlDefault = localhost:8008, both
as the option's default and as a sentinel the daemon unit compared
against to decide whether to write HIVE_MATRIX_URL. Now nullOr str,
default null, the guard is != null, and the doc says what forge.url's
already says: null means "no matrix", not "guess one".
- nix/host-modules/hive-c0re/environment.nix: forwarded
http://127.0.0.1:<port> when no gatewayHost was set. hive-c0re shares
the host netns so it reads as harmless, but the value is handed to
agents, which do not -- there it names the agent itself. Now forwarded
only when there is a gateway vhost to name, matching the guard
HIVE_MATRIX_PUBLIC_URL already uses twelve lines below.
- hive-matrix-mcp: paths::DEFAULT_HOMESERVER was the same address
compiled in, so dropping the nix defaults alone would have left the
daemon dialling loopback inside the agent's own netns -- the very bug,
one layer down. homeserver_url() is now Option, and an account with no
homeserver is skipped with a log, exactly as one with no token is.
discover_token_accounts already refused to guess for the same reason.
Two comments taught the assumption back to the next reader ("shared host
netns means every agent container resolves localhost to the same
machine"); both now say which side of the netns boundary they describe.
MATRIX_HTTP keeps its value -- hive-c0re really does share the host
netns -- but no longer claims agents do.
Gated with nix eval against the extended agent-base config, as a pair:
with no url set the daemon unit carries no HIVE_MATRIX_URL, and with one
set it carries exactly that. Either check alone passes on a broken guard.
Deletes `TransientState`, adds `transient_kind` to `TransientCleared`, and
fixes a crash misreport — three changes over the same functions.
`TransientState` was `RunningTransient` with `agent` dropped and
`takes_container_down` renamed; that rename was the only thing it did, and
its three consumers each read a disjoint subset. `transient_snapshot` now
returns `RunningTransient` directly.
`recent_transient` was keyed by agent alone and overwritten on each clear.
An agent can clear several pills in one grace window, so a `Prebuild`
(`takes_container_down = false`) landing after a `StopForUpdate` (`true`)
left the tombstone reading `false` and the crash watcher reported a
deliberate stop as a container crash. Keyed by `(agent, label)` now, with
`recent_transient_within` folding back per agent by OR — the same question
`crash_watch` asks of the active set.
`TransientCleared` gains the label for the same reason: a client holding
two open pills for one agent could not tell which one a clear referred to.
The out-of-band suppression guard has no node and so no label; it uses
`NO_NODE_LABEL`, angle-bracketed to stay out of the `NodeKind::as_str`
namespace.
