no behaviour change: a pure move of items and tests into new modules, plus
visibility edits (pub(crate)) and path updates in sibling modules that named
crate-root items. same routes, same OpenAPI, 561 tests before and after.
why: #5470, new features stop landing in one 6.4k-line file by default.
files outside swarm-controller/src: docs/agent-lifecycle/agent-roster.md,
swarm-ui JobsPage.tsx and AgentsPage.tsx, nix/host-modules/swarm-controller.nix
and swarm-grafana.nix hold comments that named main.rs for items that moved.
The agent's state/AGENTS.md stays the truth and its harness the only
writer. The harness mirrors the file into a new `agents-md` KV bucket,
and swarm-controller serves that copy, so a read works while the agent is
stopped. An edit is a unified diff plus the revision it was made against,
sent over the agent's existing control subject; the harness refuses a
stale base, applies the diff with `git apply --check` then `git apply` to
a temp copy, and writes the file only when both pass. Fixes#5519.
Files:
- swarm-queue-client/src/agents_md.rs, lib.rs: the bucket name and
subject, the mirror value, the `ApplyAgentsMd` control command and its
reply. `AgentControl` loses `Copy` because the new variant carries text.
- hive-agent/src/swarm_agents_md.rs, main.rs: the mirror task (start,
10 s re-read, immediate republish after an edit) and the apply.
- hive-agent/src/swarm_input.rs: the control loop answers both commands.
- hive-agent/src/claude_md_watch.rs: its AGENTS.md path is shared.
- hive-agent/Cargo.toml, Cargo.lock: sha1 for the git blob id (already in
the lock), tempfile moves from dev to runtime for the apply directory.
- swarm-controller/src/agents_md.rs, main.rs: the bucket reader and
GET/PUT /api/agents/{name}/agents-md; test AppState literals get the
new field.
- swarm-controller/src/agent_control.rs: the sink hands back raw reply
bytes, so each command decodes its own reply type.
- swarm-controller-api/src/agents_md.rs: the route bodies, shared with
swarmctl.
- swarmctl/src/agents_md.rs, main.rs: `swarmctl agent agents-md get|apply`.
- nix/host-modules/swarm-nats.nix, nix/module-eval/nats-authelia.nix: the
agent's publish grant on its own `$KV.agents-md.<agent>` key.
git needs no new package: agent containers enable programs.git, and the
harness unit's PATH includes /run/current-system/sw.
The dashboard, its API, the swagger UI and the agent routes move to their
own vhost, `swarm.dashboardDomain` = `<hive>.hives.<swarm.domain>`, under
the swarm domain so authelia's session cookie reaches it. `/`, `/api/` and
`/api/docs/` ask authelia through `auth_request`, and authelia's
`operatorsOnly` rule for each hive's dashboard name lets only the admins
group in. The hive domain keeps matrix discovery and redirects every other
path to the new name.
The name rides as a SAN on the hive's own gateway leaf: the per-hive bao
role allows it, and hive-tls asks for it and checks coverage.
HTTP Basic auth is gone: the htpasswd writer and its test, the
`hivectl gateway` verbs and host-socket requests, the `gateway.auth`
options (now a removed-option error), the unauthorized page and the bcrypt
dependency. tmpfiles deletes a leftover gateway.htpasswd, which held
bcrypt hashes at 0644.
c0re hands out dashboard and agent URLs on the new name
(HYPERHIVE_DASHBOARD_DOMAIN), and the swarm controller's hive roster
carries each hive's dashboard name for the swarm UI's hive list.
Closes#3469
swarm-bao-grafana-controller-token, on the host that runs Grafana, logs in
to Grafana's API over its socket as the built-in admin (the password
swarm-bao-grafana-admin minted, #5138) and keeps a `swarm-controller`
service account that is an enabled Viewer. It mints a token for that
account and writes it to bao at
swarm/controller/swarm-controller/grafana/token under Grafana's leaf. A
ten-minute timer runs it again. The unit keeps a stored token Grafana
accepts. If Grafana refuses the stored token with 401, or bao holds
none, the unit deletes every token of the account and mints a new one.
Grafana's grant gains create/read/update on that leaf, and the
controller's gains read.
swarm-controller serves GET /api/alerts from Grafana's
/api/prometheus/grafana/api/v1/alerts. It reads the token from bao,
keeps it in memory, and re-reads bao once on a 401. The HTTP client has
5s connect and 15s request timeouts. Any failure is a 503 that names its
cause. swarm-ui gets an /alerts page listing them, built the same way as
the hives page.
This is option (c) on #5129, the operator's choice.
A store answers the revision it wrote and what it replaced, and restoring
compares against that revision, so a write that landed after the creation's
own is kept instead of overwritten. A write that changed nothing rolls back
nothing, and a key that held no value is removed rather than set to an empty
one. A test fails the second store after the first and checks the earlier
caps come back.
create_agent puts back the caps and inference settings it replaced if a
later store or the job insert fails, so a refused creation leaves nothing
behind for the name. The shared field components take an id prefix so the
create dialog and an open editor never share a DOM id. The queue check now
follows the hive roster check, the 422 is documented, and the copy says
empty rather than closed and that destroy keeps stored settings.
POST /api/agents takes optional limits and inference objects, checked by
the same rules as the two PUT routes before anything is queued and stored
ahead of the job graph. The create form gets collapsed sections for both,
reusing the fields of the detail-panel editors.
The agent's turn-state header ($SWARM.agent-state.<agent>) gains
`needs_login`, set by hive-agent from its own LoginState, so the flag
reaches the swarm without hive-c0re (mara on #5268: "id prefer the agent
container sending the info it needs login without hive").
- swarm-queue-client: `agent_login::Login`, the shared wire type, beside
`agent_inference::Effective`. `needs_login: Option<bool>` with
`#[serde(default)]`: a header from an older agent decodes as `None`
(unknown), never as "needs login" or "logged in".
- hive-agent: the header publisher reads the shared LoginState cell.
Every writer of that cell emits a status on the bus afterwards, so a
login change goes out on the next rebuild, not the 60 s refresh.
- swarm-controller: `agent_login::Reported` follows every agent's header
and keeps the latest flag; `GET /api/agents/status` merges it into each
row as `needs_login` (null when unknown).
- swarm-ui: AgentCard shows a warning-tone "login needed" badge when the
row's `needs_login` is true.
Refs #5268
After a rollback, a record a newer build wrote (a new enum variant, a
changed required field) stopped decoding, and the strict
`schedules::read` turned that into an error on every read and write of
the key until someone deleted it by hand.
- agent_limits / inference (one document per agent): an undecodable
document reads as unset, with a WARN naming the bucket, key and error.
The PUT's "equal to stored, skip the write" shortcut no longer applies
to an undecodable document, so a PUT of the defaults replaces it too.
- schedule definitions (one document, every schedule): salvaged per
definition, as the review-classifier run list is. An undecodable
definition is kept as its raw JSON, hidden from the list, edits and
projections, written back by every commit after the readable ones, and
its id is never minted again. A document with no list of schedules
stays an error: reading it as empty would empty every agent's key.
- per-agent agent-schedules: an undecodable key reads as no schedules
and is rewritten on the next projection, even when the agent has none.
`schedules::read` is replaced by `read_or_default`; `wanted` keeps its
own strict read.
Closes#5193
Every run is recorded when it ends: a try-out when its reply settles it,
a requested review once its review is posted or the post fails, and a
request turned away by a full queue once its comment is posted. A
duplicate request that starts nothing is not recorded. The newest 100
are one JSON array under `recent` in a new controller-owned KV bucket,
`review-classifier-runs`, written with compare-and-set as
`schedule-definitions` is (five attempts). A failed write is logged; the
review is already posted by then.
Each recorded run is also one info event, "review classifier run
finished", with the record's fields as tracing fields. The controller
logs natively to the journal, so they reach VictoriaLogs as F_<NAME>.
GET /api/review-classifier/runs returns the list, newest first, gated
by the gateway like the try-out GET. post_classifier_review now returns
the posted review's html_url, which the record keeps as review_url.
Closes#5153, part of #5096.
systemd ignores `08%` and `085480%` for CPUQuota= and `08%` for MemoryMax=
("Invalid ... ignoring"), which leaves the agent uncapped. `hundredths` now
refuses a whole part that starts with `0` unless it is exactly `0`, for both
fields. `0.5%` and `0.01%` stay accepted.
systemd ignores a CPUQuota= or MemoryMax= it can't parse ("Invalid ...,
ignoring") and runs the unit without that limit. A swarm cap replaces
the hive's answer, so such a value left the agent uncapped while the
route, GET and the dashboard all said it was capped. argus on #4268 (R3)
found values the route took that systemd ignores: 12.345%, 400.123%,
0.001%, 17000000T, 99999999999999999999T and 99999999999999999999%.
The validators now accept a subset of what systemd parses, measured
against `systemd-analyze verify` (systemd 260):
- a percentage takes at most two decimals and is above zero, up to 100%
for memory_max and 21474836.47% for cpu_quota (systemd keeps the quota
in hundredths of a percent in a C int, not a u64)
- a size is one parse_size term: digits, an optional fraction, then
nothing, B, K, M, G or T, case-sensitive. The whole part and the
fraction digits fit u64, the whole part (plus one with a fraction)
fits u64 once scaled, and the byte count is at least 1 and below
2^64 - 1, as systemd checks them.
P and E, which systemd reads, stay refused because hive-c0re's validator
refuses them, and one value the hive refuses stops every cap update on
that hive. Values are stored as given: lower-case suffixes and a B
after a multiplier are refused rather than normalized, as systemd
refuses them.
The newline-injection values from the hive's test are in both bad lists
and go through the router in a_cap_with_a_second_line_is_a_400_and_the_caps_stay.
GET reads through a new agent_limits::open that returns None for a
missing bucket, answered as {}, instead of creating the bucket.
An agent's CPU and memory caps, set from the swarm. Keyed by the agent
alone, in a new `agent-limits` KV bucket that swarm-controller alone
writes, the same shape as `agent-inference` (#5034): mara on #4268,
"agents are not tied to a hive. dont tie the limits to the hive."
PUT {"cpu_quota": "400%", "memory_max": "8G"} every field optional,
replaces the stored value
GET the stored caps, {} when there are none
DELETE 204
PUT refuses an agent no hive's wanted state declares (as the inference
route does), unknown fields (422), zero and anything systemd does not take,
before the queue is asked, and stores memory in the spelling systemd takes
(8gb -> 8G). The hive hands these values to systemd verbatim.
The routes sit under /api/, behind the swarm UI vhost's authelia
subrequest like every sibling; the core-toggle module-eval case pins that
gate.
The bucket's reader on the hive comes in the next commit.
Contributes to #3865.
