d3a92f1033 fix(controller,worker): dual-state worker loss + resend actual job state (bug-1509 P3)
Phase 3 (B1 dual-state + B2): a job never lingers as RUN when its worker
is lost.

Dual-state B1 (user-approved): RDHUP (worker TCP dropped = confirmed dead)
marks its RUN jobs EXIT immediately (mark_worker_jobs_exit). Heartbeat
timeout (unknown) keeps them UNKWN+TRANSIENT awaiting reconnect
reconciliation; the TRANSIENT TTL GC is the backstop. handle_worker_leave
now calls mark_worker_jobs_exit (was mark_worker_jobs_unknown in Phase 2).

B2 (worker side): resend_job_status now checks the recovered process is
alive (kill(pid,0)) before re-reporting RUN — a dead process is reported
finished so the controller converges to EXIT instead of a stale RUN. And
resend_job_status runs on EVERY rejoin (checking_connection), not just
startup, so a reconnecting worker's jobs are reconciled (clears UNKWN via
the existing notify_jobstart claim path).

Design: docs/Job-Finish-Robustness-设计文档.md §4.4 (dual-state decision).

Unit test: worker RDHUP marks jobs EXIT (not UNKWN).

c091a8dae0 fix(controller,worker): sched worker resval UAF + execuser fallback to nobody
bug-1506 (controller): sched_worker_change pointed w->host.resvals_to_sched
at resvalist.data, then xlist_fini freed it — a concurrent reader (the
WORKER_JOIN hook encoding the worker's resvals) hit an ASAN
heap-use-after-free that crashed the controller and failed every job. Take
ownership of the resval data via MOVE_PTR (mirrors collect_resvals_workers);
the prior array is intentionally leaked (freeing it races the same readers).

bug-1507 (worker): the apiserver's bug-1500 execuser fix sent the submit
user ("admin") as execuser, but that user does not exist in the worker
host's /etc/passwd. systemd failed the worker unit with EXIT_USER (217),
so every job died immediately after submit. job_start_local_task now
checks the execuser with getpwnam() and falls back to "nobody" when the
user does not exist.

Verified with a full job lifecycle (submit -> RUN as nobody -> DONE) on
the clean build: all 4 daemons healthy, zero ASAN.

3a2094a461 Merge branch 'working' into job_peek_lchen
job_peek_lchen: Add fetchfile feature (job output/error peek proxy)
working: HA/Raft infrastructure (consensus, replication, config mgmt)

Conflict resolution summary:
- controller.capnp: fetchfile @41, fetchfilereply @18, fetchfilemsg @30
- cluster.c: bifurcated OPCode_reply for fetchfile + config-push ACK
- job.c: kept full fetchfile pending-request subsystem (~183 lines)
- request.c: kept both xce_fetchfile_req() and XCE_RETRY_DEFAULTS
- helper.c: added missing preVoteRequest/preVoteReply mappings
- All 15 new test registrations (test_cbuf.c + 14 HA tests)

94f50ce6e1 fix(scheduler,cli): bug-1453/1454/1455/1456 remove dead CA-cert plumbing, fix scheduler HA config bugs
bug-1453: remove unused client-side CA-certificate plumbing. C-side:
drop ca_cert_path from xce_cluster_config_t, do_connect()'s ca_cert
param, --ca-cert flags on worker/scheduler, and controller's cert
population (TLS is server-side only, SSL_VERIFY_NONE everywhere on
the client side already, verified zero SSL_CTX_load_verify_locations
calls in the C tree). Go-side: delete xcecli's self-signed cert
TOFU-pinning flow (cmd/auth/cert/*), CACert field, SetRootCAs/
loadRootCAs, and every call site.

bug-1454: fix xcecli_ctx_t leak in scheduler.c sched_init() — the
unconditional initial ctx_init was never freed before the HA
candidate loop re-initialized it on the first iteration.

bug-1455: sched_init()'s memset(sched, 0, ...) was silently wiping
sched->cluster_cfg that main.c had populated from --peers just before
calling sched_init(), so --peers was always ignored and the scheduler
fell back to the hardcoded localhost:9990 single-host default.
Restructured sched_init() to take cluster_cfg as an explicit parameter
(assigned after the memset) instead of relying on caller-side
ordering with a separate sched_set_cluster_cfg() setter, which is now
removed.

bug-1456: revert an unsafe stack-local xce_client_config_t introduced
while fixing bug-1455 — xcecli_ctx_init() stores that pointer as
ctx->conf and client_failover.c dereferences it for the ctx's entire
life (runtime reconnect), so a per-loop-iteration stack copy would
dangle the moment sched_init() returned. Back to mutating the
caller-owned, process-lifetime config in place.

Verified: full ASAN build (all components), meson test suite 9/9 OK,
manual scheduler testsuite 15/15, Go build/vet/test all pass.

7e4528a0b9 refactor: consolidate parse_peers into xce_parse_peers in libxce
Three identical static copies (controller, worker, scheduler) replaced
with a single xce_parse_peers() in src/lib/cluster.c.

The libxce version is the canonical implementation: stores the logical
name from 'name=host:port' syntax so daemons on the same dev host can
identify themselves by name rather than IP address.

9bc84f1ca1 fix: add xcecli_ctx_fini() before continue in HA candidate loop (resource leak) 2026-05-08 03:15:26 +00:00
b75703ba6b feat: wire HA candidate-list reconnect into worker+scheduler join paths
Worker (xcecd):
- Add xce_cluster_config_t cluster_cfg field to controller_connector_ctx_t
  (controller_connector.h includes xce/cluster.h)
- Populate cc_ctx->cluster_cfg from parsed cluster_cfg after xcecd_start()
  sets cc_ctx (main.c, removes the P3 placeholder)
- Replace xcecd_join_cluster() single-shot connect with a candidate-iterating
  loop: tries each candidate, calls xcecli_stop() before the next attempt,
  falls back to the original single-host path when candidates_count == 0

Scheduler (xce_scheduler):
- Add xce_cluster_config_t cluster_cfg field to xce_scheduler_t
  (scheduler.h includes xce/cluster.h)
- Add sched_set_cluster_cfg() setter
- Replace the hardcoded xcecli_start/xcecli_join pair in sched_init() with
  the same candidate-iterating pattern; original single-host path preserved
- main.c calls sched_set_cluster_cfg() before sched_init() when --peers given
  (removes the P3 placeholder comment)

checking_connection() already calls xcecd_join_cluster() on retry, giving
the worker free reconnect-after-failover behaviour for no additional code.

fd9cfce1c1 feat: P2.5-5/6 add --peers/--ca-cert parsing to worker+scheduler with validation
Worker (P2.5-5):
- Added parse_peers() static helper to src/worker/src/main.c
- Switched getopt to getopt_long to support --peers and --ca-cert long options
- When --peers is given: parses into xce_cluster_config_t, calls
  xce_cluster_config_validate(), logs INFO with candidate count/identity/ca_cert
- If validation fails: prints clear error and exits(1)
- WARN logged when candidates_count > 3
- Backward compatible: no --peers falls back to existing single-controller path

Scheduler (P2.5-6):
- Added parse_peers() static helper to src/scheduler/src/main.c
- Extended argp struct with --peers (-P) and --ca-cert (-C) options
- Same validation/logging pattern as worker
- Backward compatible: no --peers falls back to existing single-controller path

Tests (new):
- src/lib/testsuite/test_cluster_parse.c: 8 unit tests for parse_peers logic
  (single entry, multiple entries, no-name format, empty/null/missing-port errors,
  name-stripped correctly, MAX_HA_CANDIDATES cap respected)
- Registered in test.c and meson.build
- All 8 tests GREEN; 3 pre-existing failures in unrelated GC/CSE tests unchanged
