- add heartbeat.go with heartbeatIntervalSecs var, SetHeartbeatInterval, runHeartbeat (no build tag, CGO-free)
- add heartbeat_test.go with 5 tests covering interval validation and goroutine lifecycle
- add StartHeartbeat to clib.go (CGO impl calling xcecli_heartbeat)
- remove SetHeartbeatInterval stub from stub.go (now real code in heartbeat.go)
- remove TestSetHeartbeatInterval_StubNoOp from stub_funcs_test.go
- call SetHeartbeatInterval in OnClusterUpdated to track backend-pushed interval
- call backend.StartHeartbeat in cmd/main.go after backend registration
Add OPCode_notify handler in go_push_handler top-level switch
(not inside handlePush) to receive resource value updates from
the controller via xce_notify_data_t/schedUpdateResvals.
- Add 8 CGO union accessors for xce_val_t (which, i32, i64,
u32, u64, fval, str, bool) since CGO cannot access union fields
- Add handleNotifyData() dispatching NotifyData_data_schedUpdateResvals
events, iterating xce_resval_list_t and calling cResvalToDistribution
- Add cResvalToDistribution in convert.go with 7 separate switch
cases for Value_u_* union discriminants (no combining i32/i64)
- Add rawResvalData + rawResvalToDistribution pure-Go version
in convert_pure.go for testability without CGO
- Add 10 TDD tests covering all 7 value types, nil val guard,
unknown discriminant, and boolean false
- All 42 backend tests passing
Add four function stubs to backend/stub.go for the !cgo build path:
- StartHeartbeat(ctx context.Context) — no-op (heartbeat not available)
- SetHeartbeatInterval(secs int) — no-op (interval update not available)
- EvalSelectForHost(hostname, selectExpr string) error — returns errNoCGO
- Cleanup() — no-op (no C resources to release without CGO)
TDD: four tests in stub_funcs_test.go verify stubs behave correctly
(no-op functions don't panic, error stubs return errNoCGO). All backend
tests passing.
Routes and RBAC entries already existed from prior P0-2a/2b work. This
adds three TDD tests that lock down the RBAC invariants:
- TestRBAC_HostControl_ClusterAdminOnly: cluster_admin has host:control
with domain=all; basic_user must NOT have host:control
- TestRBAC_HostView_BasicUserHasAccess: basic_user has host:view with
domain=all; queue_admin must NOT have host:view
- TestRBAC_HostControl_DomainTypeIsAll: cluster_admin host:control
domain type must be "all" (not hostgroup)
All apiserver tests passing.
1. Add //go:build !cgo to control_host_test.go so the stub-testing
tests only run in non-CGO builds, matching the stub.go build
constraint. Clean up dead nil check in SignatureCompiles test.
2. Replace two independent if-statements for actionType mapping in
ControlHost with a map lookup + explicit guard, consistent with
ControlQueue's ActionMap pattern. Prevents silent zero-value
actionType if SupportedHostActions expands later.
- backend/clib.go: Replace ControlHost stub with real implementation
using xcecli_hostctrl, following the same pattern as ControlQueue
- controllers/hosts.go: Remove package-level allFlag variable;
preCheckHostControlRequest now returns (bool, error) so the allFlag
is a local value in the caller, eliminating the data race
- controllers/queues.go: Same fix for preCheckQueueControlRequest
- Add unit tests for both preCheck functions verifying return values,
error cases, and concurrent safety
- Add compile-time verification test for ControlHost stub signature
Add the full call chain for host control operations from the Go API
server through the C library to the controller:
- schema/controller.capnp: HostControl struct + hostctrlmsg @21
in Request.body union
- include/typemap.h: xce_hostctrl_t* hostctrlmsg in body union
(placed after @20 clrpreasonmsg, matching capnp ordinal)
- include/client.h, xceapi.h, request.h: declarations for
xcecli_hostctrl, xce_hostctrl, xce_hostctrl_req
- lib/client.c: xcecli_hostctrl (validate + delegate to xce_hostctrl)
- lib/xceapi.c: xce_hostctrl (validate ctx state + send + wait reply)
- lib/request.c: xce_hostctrl_req (validate hostname/empty/nil,
accept only HOST_OPEN/HOST_CLOSE, reject HOST_TAG/UNTAG)
- lib/helper.c: Request_body_hostctrlmsg cases in
xce_request_body() and xce_request_msg_name()
- controller/cluster.c: OPCode_hostcontrol dispatch
- controller/include/cluster.h: do_hostcontrol_op declaration
- controller/worker.c: do_hostcontrol_op + fix pre-existing
goto-clean bug in worker_ctrl that leaked write lock and
reference on HOST_OPEN/HOST_CLOSE no-op paths
TDD: 8 xce_hostctrl_req validation tests (null ep, null ctrl,
null/empty hostname, HOST_DO_NONE no-op, HOST_TAG/UNTAG reject,
negative action reject, HOST_OPEN/CLOSE accept via xce_request).
116/116 xcelib tests pass. CGO_ENABLED=0 Go backend tests pass.

Start from existing entry and apply this-source's fields, rather than
starting from incoming and restoring the other-source's fields. The new
pattern makes it immediately clear which fields each push type WRITES,
without having to reason about which fields are being "restored".
OnHostUpdated keeps the merged := *incoming + if ok guard because the
worker push also populates HostModel/HostType from attrs; config-sourced
values must only win when a prior config push has already set them.
All 37 backend unit tests pass.
Wires the remaining cluster_config_t data into the notification pipeline:
- dispatchConfigPush() extracted as a pure-Go helper (CGO-free, testable)
that drives OnQueueUpdated, OnResourceUpdated, OnHostConfigUpdated, and
OnClusterUpdated from a single config push event
- handleConfigPush() delegates to dispatchConfigPush via the new helper,
eliminating the previous inline loops
- OnHostConfigUpdated and OnClusterUpdated added to NotificationHandler
interface and implemented with partial-merge semantics in DefaultHandler
- rawHostConfigData/rawHostConfigToModel and rawClusterData/rawClusterToModel
added to convert_pure.go with their CGO extraction counterparts in convert.go
Safety fixes from code review:
- OnHostUpdated, OnHostConfigUpdated, OnClusterUpdated now copy *incoming to
a local merged value before mutation, closing the TOCTOU window between
store.Get and store.Put under concurrent pushes
- cClusterConfQueues and cClusterConfResources gain nil-pointer guards
matching the existing guard in cClusterConfHostConfigs
- handleConfigPush gains an explicit gHandler nil check
- cClusterConfToClusterInfo returns nil on empty clustername (prevents phantom
empty-key write to store.Clusters); handleConfigPush logs a warning when nil
- 36 unit tests passing (CGO_ENABLED=0)
- Fix issue to xce_get() api cause client side crash
- add parse resreq section
- add rusage parser
- parse resreq with basic support alternative & compound, still miss select
