Destroy was a straight-line async fn with no queue node behind it, so
nothing in the graph could answer "is this container going down on
purpose?". That gap is why an imperative crash-watch suppression guard
existed: an RAII handle held for the operation's duration, a second way
to say what every other lifecycle op already says through its node.
Reuse the existing Stop node rather than teaching a new node to stop
things:
Stop -> DestroyContainer -> (PurgeState) -> DestroyBookkeeping
Stop already declares takes_container_down honestly, so the suppression
is now derived from the graph like every other op's. It also turns the
precondition into an edge: DestroyContainer runs only under a completed
Stop, so it operates on an already-stopped container and carries
takes_container_down = false permanently. A container still alive at
that point is a real bug and stays loud instead of being absorbed by a
flag -- which matters because a wrong true silently swallows a crash
while a wrong false only costs a spurious event.
Removes suppress_crash_watch, CrashWatchSuppression, crash_suppressed,
crash_watch_suppressed and NO_NODE_LABEL. The migration call sites went
with the obsolete startup migrations, so destroy was the last caller and
intent now has exactly one home.
destroy() becomes a submit-and-return, matching every sibling endpoint
(rebuild, kill, restart, start, pause, resume) -- it was the only
lifecycle op that awaited its work. The container rescan moves into the
bookkeeping tail, so ContainerRemoved now arrives after the 200 rather
than before it.
Also drops an orphaned doc-comment in coordinator.rs: two stacked blocks
where only the second described crash_suppressed, the first documenting
a field that no longer exists. Removing the field would have re-pointed
it at recent_transient.
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 `*_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.
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.
Swagger UI's endpoint-list row already shows the HTTP method badge +
path for every row, so restating `METHOD /path` at the start of a
handler's own summary is pure duplication. Strips that self-referential
prefix from every summary that has it and re-capitalizes what follows
as a standalone sentence.
Left two false positives untouched: misc_api.rs's operator-inbox
summary cross-references a *different* sibling endpoint
(mark-all-read) for context, and topology.rs's SetParentForm struct
doc happens to mention its endpoint's path but isn't a handler summary
line. Both are legitimate, not redundant.
utoipa splits a handler's doc comment on the first blank `///` line:
everything before it becomes the OpenAPI `summary` (shown in Swagger
UI's collapsed endpoint-list row), everything after becomes the
`description` (only shown once that row is expanded). With no blank
line, the whole doc comment becomes the summary and the description is
empty — which is what every handler in hive-c0re/src/dashboard/ was
doing, so the all-endpoints list showed full multi-sentence prose next
to every route instead of a short one-liner.
For every `#[utoipa::path(...)]`-annotated handler across the 19 files
in that module:
- Inserted a blank `///` line after the first short sentence/clause so
utoipa's split produces a real summary + description, where the doc
comment had more to say. Left already-short single-clause docs alone
(nothing to split).
- Where a query struct derives `IntoParams`, moved param prose that
duplicated a field's own doc comment out of the handler doc (the
field already documents itself in the generated spec), or added a
field doc where the handler explained a param that had none.
No behavior changes — doc comments and `params()` description text
only. Verified `cargo build -p hive-c0re` (clean) and `nix fmt` (zero
changes) after.
Closes#2969
`Coordinator::set_paused` wrote the marker directly with `std::fs::write`
from hive-c0re, which runs as the unprivileged `hive-core` user. The
agent's harness dir is chowned to the agent user on every container boot
(`user.nix`'s activation chown), mode 0755 — so hive-core can stat the
marker but gets EACCES creating or unlinking it. Pause therefore only
ever worked on an agent that had never booted; the read side works
because a stat needs traverse, not write, which is why the paused pill
and `is_paused` looked healthy.
Route both directions through hive-priv, the root helper that already
owns the other writes into agent-owned directories:
- `PrivRequest::SetAgentPaused { agent_name, paused }`, with the marker
filename constant moved to hive-priv-sock. That is the narrowest crate
all three sides share (hive-priv deliberately does not depend on
hive-sh4re, which re-exports it for the in-container resolver). A
private copy on any one side would break pause silently, since every
reader just sees "no marker".
- `write_agent_state_file` generalised to `write_agent_dir_file`, taking
the target directory: `state/` and `harness/` are both agent-owned,
which is the same reason both need root.
- resume unlinks via `remove_file`, which acts on the leaf and never
follows a symlink — an agent could otherwise plant a link at the
marker path and have root delete an arbitrary file.
`Coordinator::set_paused` becomes an async round-trip; its three call
sites were already async. Both directions stay idempotent because the
dashboard toggle and `hivectl pause|resume` fire without reading the
current state first.
Adds CPU/memory cap columns and an inline edit form to the container-load
table in /core.html, backed by a new POST /api/resource-limits/{name}
dashboard endpoint.
## Backend (hive-c0re)
lifecycle_ops.rs — new post_resource_limits handler:
- Parses ResourceLimitsForm { cpu_quota, memory_max } (both optional; empty
string = clear override, fall back to hive-wide default).
- Validates each non-empty value via resource_limits::validate_cpu_quota /
validate_memory_max — returns 422 UNPROCESSABLE_ENTITY with a human-
readable message on invalid input so the dashboard can surface it inline.
- Calls meta::commit_resource_limits (staged git write under META_LOCK, same
as hivectl set-limits).
- Re-applies the drop-in immediately via lifecycle::write_dropins so the new
ceilings take effect on the next container start without waiting for a
rebuild.
- Triggers rescan_containers_and_emit so ContainerView.cpu_quota/memory_max
update via SSE without waiting for the next periodic sweep.
dashboard/mod.rs — registers the route:
POST /api/resource-limits/{name}
## Frontend (core.js + system-sections.css)
core.js:
- containersState derived from /api/state snapshot alongside tombstonesState
— supplies configured cpu_quota/memory_max to the LOAD table.
- lastLoadRows stash lets SSE-triggered re-renders call renderContainerLoad
without waiting for the next 5s poll.
- renderContainerLoad: adds cpu cap / mem cap columns (muted; tooltip
'configured ceiling — takes effect on next start') sourced from
ContainerView, plus a per-row S3T toggle button that expands an inline
edit form with cpu_quota / memory_max text inputs and a S4V3 button.
The edit form shows a restart hint, surfaces validation errors inline, and
collapses on success.
- container_state_changed SSE handler: updates containersState in place and
re-renders the LOAD table so the cap columns flip immediately after a save.
system-sections.css:
- CSS for the new cap columns (.cload-cap-th, .cload-cap) and inline edit
form (.cload-edit-row, .cload-edit-form, .cload-edit-label, etc.).
- Remove dead .rqe-step rule (step sub-step label retired from the wire in
'job_queue: retire the now-off-wire step sub-step label').
When ContainerView.paused is true, show a clickable yellow `⏸ paused`
badge on the agent card that POSTs to the new /api/resume/{name} endpoint
to un-park the turn loop. The badge doubles as the resume button so the
state is self-documenting and one click to fix.
The agent action menu gains ⏸ P4US3 (when not paused) and ▶ R3SUM3
(when paused), orthogonal to the running/stopped start/stop actions.
On the backend, /api/pause/{name} and /api/resume/{name} POST routes
wire to Coordinator::set_paused and trigger an immediate rescan so the
badge flips via the existing SSE ContainerUpdate without polling.
Depends on the ContainerView.paused field and Coordinator::set_paused
added in the parent PR.
Restart now offers the same graceful-vs-hard choice stop already has:
single-agent menu item and the bulk-select action bar both grow a
'restart gracefully' checkbox that routes through the existing
submit::graceful_restart DAG (signal -> drain -> stop -> reconcile)
instead of a hard restart. Backend gains a ?graceful=true query param
on POST /api/restart/<name>, mirroring post_kill's shape (renamed
KillParams -> GracefulParams since it's now shared).
Hive-wide `stop` / `start` / `restart` emit ONE DAG with a per-agent
subgraph each (concurrent on their own leases) instead of N DAGs — and each
subgraph is now built dynamically from the agent's live running state rather
than a fixed template shape:
- online agent: the full stop→reconcile (restart: stop-for-update→reconcile)
chain; `graceful` prepends signal→drain.
- offline agent: just `SetWanted → Reconcile` (nothing to quiesce/stop; a
restart of a down agent is really a start).
The head `SetWanted` (intent) and tail `Reconcile` (convergence guarantee)
are always present; only the mechanical `Signal`/`Drain`/`StopForUpdate`
nodes are state-conditional. Keeping `Reconcile` in every shape closes the
TOCTOU window — a race-up between the `is_running` read and node exec is
still converged in-DAG (with `StopForUpdate`-noop as the backstop) — with no
reliance on an external reconcile sweep.
The state-aware assembly needs an async `is_running` read, so it moves out
of the pure/sync `templates.rs` into `submit.rs`, layered as pure
`*_chain(running)` → pure `*_spec(targets)` (the unit-test seam) → async
`*_many` (reads live state + submits). `templates.rs` keeps only the shared
pure primitives (`node`/`after_ok`/`rebuild_nodes`).
Callers await the now-async submit fns (server, dashboard, socket_server).
Tests exercise both the online and offline shapes via the pure `*_spec`
seam. docs/coordinator.md shapes updated.
jobs are now DAGs of primitive nodes (prebuild, stop-for-update, swap,
reconcile, signal, drain, ...) driven by one scheduler with N build
slots + per-agent lifecycle leases. per-agent power intent (wanted
up/offline) is durable in agent_power.sqlite; Reconcile nodes converge
observed state to it. kills the graceful-stop watcher thread, the
deferred-start follow-up, and the cascade pre-enqueue (fan-out on
MetaLock completion instead). tracker: #2166
The per-agent and manager sockets ran two parallel dispatchers with
duplicated lifecycle handlers (agent-side topology-gated, manager-side
ungated) plus a manager-only handler set. Collapse to one parameterized
server in socket_server.rs:
- one serve() + dispatch(req, agent, privileged, coord); start() binds
the per-agent sockets (privileged=false), start_manager() binds the
manager socket (privileged=true).
- each lifecycle/config handler (start/restart/kill/update/init_config/
apply_commit) merges its dual: the topology guard (require_child /
require_new_child) runs only on the !privileged path; init_config
records the requester as parent only when !privileged. restart keeps
the orthogonal, capability-gated + audited infra-container branch.
- the agent-state queries (loose-ends / reminder count + rollup) branch
on privileged: privileged keeps any-target + the "*" hive-wide sweep
(query_agent_state-gated), non-privileged keeps the topology/cap gate.
- the privileged-only verbs (schedules / meta-inputs / get_logs) plus
the submit/schedule/watchdog helpers move into socket_server; they are
reached via dispatch_privileged_only(), which rejects the whole group
on a non-privileged socket.
- delete manager_server.rs; repoint refs; merge the test modules.
No behavior change: the topology guard still applies on every
non-privileged lifecycle call, the privileged socket still acts on any
agent, and privileged-only verbs are still rejected on agent sockets.
