HostFunctions is a process-wide singleton (one per gateway engine).
Its `invCtx` field is shared across all WASM instances. For STATELESS
execution the executor sets/clears it per-call but the lock is
released before WASM runs — two concurrent invocations can race on
the field and one's host call can read the other's identity. Window
is microseconds.
For PERSISTENT WS the bug was much worse: invCtx used to be bound
ONCE at instantiation and reused for the connection's lifetime. Two
simultaneous persistent WS connections from different namespaces /
wallets overwrote each other's invCtx, and EVERY subsequent
function_invoke / GetCallerJWTSubject / GetCallerWallet / GetSecret
call from inside the WASM read whatever was bound LAST. Result:
silent identity leak across tenants for as long as the connections
overlapped.
Fix: per-call invCtx propagation through Go's context.Context.
wazero passes the ctx given to api.Function.Call through to host
function callbacks, so every WASM-host hop carries its own invCtx.
- pkg/serverless/invocation_context.go (new): WithInvocationContext +
InvocationContextFromCtx helpers using an unexported invCtxKey.
- pkg/serverless/hostfunctions/invocation_context.go (new):
currentInvocationContext(ctx) — ctx-attached invCtx wins over the
singleton field.
- All host accessors (FunctionInvoke, GetEnv, GetSecret, GetRequestID,
GetCallerWallet, GetWSClientID, GetCallerClaim, GetCallerJWTSubject)
now route through currentInvocationContext(ctx).
- pkg/serverless/persistent/instance.go: every export call's ctx is
wrapped with the per-instance invCtx before being passed to wazero.
- pkg/gateway/handlers/serverless/ws_persistent_handler.go: invCtx is
built per-frame and attached to ctx, not stored on a shared field.
- pkg/serverless/engine.go: removed the SetInvocationContext call at
InstantiatePersistent (no longer needed; ctx carries it).
Stateless still uses the singleton field — its race is latent since
the host-functions split and migrating it is a separate scoped
change.
Tests:
- hostfunctions/invocation_context_test.go covers ctx-wins-over-singleton.
- gateway/handlers/serverless/ws_persistent_handler_test.go covers the
per-frame ctx wiring.
- cli/functions/build_test.go is new coverage for the build path
touched in this change.
VERSION bumped to 0.122.24.
The previous fix (v0.122.22) made `InstantiatePersistent` call `_start`
to bootstrap TinyGo's runtime, then catch the resulting ExitError(0).
That got past init, but the module STILL died — wazero's stock
`proc_exit` implementation calls `mod.CloseWithExitCode(exitCode)`
before panicking, which invalidates the module regardless of what
the caller does with the panic. Every subsequent call to ws_open /
ws_frame / ws_close / orama_alloc returned ExitError(0) ("module
already closed").
Wazero exposes no flag for this — the close is hard-coded. The only
intercept point is to override `proc_exit` at the WASI host-module
boundary. Documented pattern at imports/wasi_snapshot_preview1/wasi.go
lines 111-127.
Fix: build the WASI host module manually so we can override
`proc_exit`:
- exit code 0 → panic ExitError(0) BUT do NOT close the module.
This is TinyGo's "_start completed cleanly" signal; the module's
other exports must stay callable for the persistent lifecycle.
- exit code != 0 → preserve standard WASI behavior (close + panic).
A non-zero exit is a genuine app-signaled failure; we want
`proc_exit(N != 0)` to behave exactly as upstream does.
The InstantiatePersistent caller already distinguishes the two cases
via errors.As + ExitCode() check — added in v0.122.22, no change here.
Safe for stateless functions on the same runtime: the stateless
execution path closes its own module after each invocation, so the
"module stays alive on exit 0" override has no effect on that path.
VERSION bumped to 0.122.23.
InstantiatePersistent passed WithStartFunctions() with no args,
explicitly disabling both wasi entry points. The intent was to skip
main(); the side effect was leaving the TinyGo runtime
uninitialized. The first call to any export traps via
wasmExportCheckRun and managed-memory ops panic. Every persistent WS
function was effectively dead since plan #06 landed.
Earlier patch in this thread restored the call but only handled
wasi-reactor builds (_initialize). AnChat's rpc-router is a wasi
command build (`_start` export only, no `_initialize`) — wasm-objdump
confirms — so the reactor-only fix still left it broken.
This fix tries `_initialize` first, falls back to `_start`, and
bounds whichever runs with a 5s timeout so a buggy main() can't hang
instantiation forever. Logs the chosen hook at Debug, warns when
neither is exported.
Still pass WithStartFunctions() (no args) so wazero doesn't
auto-call `_start` during InstantiateModule — we want full control
over which hook runs and the timeout that bounds it.
VERSION bumped to 0.122.22.
Register() writes the four ws_* columns (ws_persistent,
ws_idle_timeout_sec, ws_max_frame_bytes, ws_max_inflight_per_conn) to
the functions table, but every read path — Get, List, GetByID,
GetByNameInternal — silently dropped them from the SELECT. functionRow
had no fields for them either. Result: fn.WSPersistent was always the
zero value (false) at runtime, no matter what the DB row said. Every
WS function ran in per-frame stateless mode regardless of its
`ws_persistent: true` config.
AnChat's rpc-router was the canary: it relies on per-connection
instance state (request_id ↔ reply correlation, subscription
bookkeeping) that the stateless model destroys every frame. The
gateway telemetry envelope still reached the client
({request_id, status, duration_ms}) so the failure looked like
"function works, frames don't" — every RPC timed out at 15 s.
Fix: include the four columns in every SELECT, add the matching
functionRow fields, and copy them into Function in rowToFunction.
No schema change (columns have been in migration 011 from the start).
Regression tests in registry_ws_columns_test.go cover the Get / List
paths against an in-memory SQLite that mirrors the production DDL.
VERSION bumped to 0.122.21.
handleNamespaceGatewayRequest rewrites r.Host to the backend target
IP:port (e.g. "10.0.0.6:10004") before forwarding. The original
public host (e.g. "ns-anchat-test.orama-devnet.network") is preserved
in X-Forwarded-Host. checkWSOrigin in both pubsub/ws_client.go and
serverless/ws_handler.go was comparing the client's Origin against
the proxied r.Host only — so every browser / RN-iOS WS upgrade was
rejected 403 because their Origin's public hostname can never match
10.0.0.6.
curl probes don't send Origin, so curl returned true unconditionally
and the bug was invisible to operator smoke tests. AnChat's iPhone
WS clients hit `code=1006 reason="Received bad response code from
server: 403"` for ~24h.
Fix: prefer X-Forwarded-Host (the original public host) when present,
fall back to r.Host for direct (non-proxied) connections. Applied
identically to both WS handlers. Regression test in
serverless/ws_origin_test.go covers the proxy-hop case, no-Origin
case, and direct-connection case.
This is the real fix; v0.122.19 only closed a separate silent-forward
auth hole that produced opaque 401s on a different code path.
VERSION bumped to 0.122.20.
Root-cause hardening for bug #240 and #249's "intermittent 401 over WS"
reports. handleNamespaceGatewayRequest previously had a third code
path beyond "auth ok" and "auth error": when validateAuthForNamespaceProxy
returned empty namespace AND empty error (i.e. "no credentials found"),
the request fell through to a silent forward to the namespace gateway
WITHOUT internal-auth headers. The namespace gateway then rejected
with 401 "missing API key" in ~60µs.
From the client's perspective: opaque 401.
From our side: only the namespace gateway logged it, and that tier
can't validate API keys (they live in the main cluster RQLite), so
the operator had no signal that the main gateway had even seen the
request. AnChat's intermittent 401-on-WS reports went unsolved for
this exact reason.
Fix:
- Explicit reject at main when no credentials extracted AND path
isn't public. Returns 401 with WWW-Authenticate: Bearer realm and a
clear message naming the three accepted credential sources.
- Rich structured logging on every WS upgrade auth outcome: presence
of api_key/token/jwt query params, Authorization + X-API-Key
headers, Connection/Upgrade headers, Origin, User-Agent, client IP,
raw query length. Steady-state stays low-noise: success path logs at
debug, reject paths log at warn.
- Namespace-mismatch reject (existing branch) now also logs.
VERSION bumped to 0.122.19.
Upstream publishes the checksums asset as a plain "checksums.txt" at
the release root, not "ntfy_<VER>_checksums.txt". The version-prefixed
URL we were constructing 404'd, so InstallNtfy bailed in the
download-binary step and ntfy never landed even after we wired
InstallNtfy into the pre-built install path.
Verified against the v2.11.0 release assets list. If a future version
changes the naming convention, the install will 404 loud and this URL
gets bumped in the same PR as ntfyVersion.
VERSION bumped to 0.122.18.
Phase 2b auto-detects pre-built archive mode and routes to
installFromPreBuilt(). That path copies bundled binaries (caddy, orama,
gateway, …) into place but never called InstallNtfy() — because ntfy
is downloaded from upstream github, not bundled. Result: on devnet
(which always uses pre-built mode), ntfy never installed even though
the always-on code path in installFromSource() was correctly wired up.
Fix: add InstallNtfy() call to installFromPreBuilt right after the
binary deploy + setCapabilities steps, before disableResolvedStub
runs. Ordering matters because Phase 4's ConfigureNtfy chowns
/etc/ntfy/server.yml to the ntfy user, which needs to exist.
VERSION bumped to 0.122.17.
ntfy is now part of the standard node install, just like Caddy. The
binary, /etc/ntfy/server.yml, and the Caddy push.<dnsZone> reverse-
proxy block are written unconditionally on every node, and the
ntfy.service starts as part of the standard service order.
Why uniform: ntfy listens on 127.0.0.1:NtfyListenPort only, reachable
exclusively via the local Caddy reverse-proxy block. Nodes that don't
serve a public push.* DNS entry just have an idle ntfy with no
inbound traffic — zero operational cost, zero attack surface change.
Removing the flag means no per-node toggling, no preference drift
between nodes, no "did we remember to set --with-ntfy" mistakes when
DNS topology changes (e.g. promoting a node to nameserver later).
Removed:
- NodePreferences.NtfyHost (yaml: ntfy_host)
- ProductionSetup.isNtfyHost field, SetNtfyHost, IsNtfyHost
- install/flags.go --with-ntfy + NtfyHost field
- upgrade/flags.go --with-ntfy + NtfyHost field + isFlagPassed helper
(was only used for --with-ntfy tri-state semantics)
- upgrade/orchestrator.go preference-load and persist for ntfy
- upgrade/remote.go --with-ntfy forwarding
Phase 2 always calls InstallNtfy.
Phase 4 always calls EnableCaddyNtfyProxy + ConfigureNtfy.
Phase 5 always enables ntfy.service.
Phase 5b always starts ntfy.service.
VERSION bumped to 0.122.16.
`orama node upgrade --node <ip> --with-ntfy --restart` parsed the flag
locally but `upgradeNode()` ran a hardcoded
`orama node upgrade --restart` on the remote — dropping --with-ntfy,
--nameserver, --force, and --skip-checks on the floor. The remote
orchestrator then read the SAVED preference (or default false for
nameserver/ntfy), so operator overrides like enabling ntfy on a
nameserver were silently ignored. Bug surfaced in devnet today:
running --with-ntfy reported success but ntfy was never installed.
Fix forwards the four passthrough flags to the remote command,
preserving the tri-state semantics for the pointer flags (nil = honor
saved preference; non-nil = explicit override).
VERSION bumped to 0.122.15.
Migration 028: namespace_push_credentials
- Per-(namespace, provider) AES-256-GCM encrypted credential blob.
- Generic schema — apns/ntfy/expo/future plug in with zero migration.
- Separated from migration 026's namespace_push_config (preferences vs
credentials, different access patterns).
pkg/push/credentials
- Manager + Registry + RQLite store; HKDF purpose "namespace-push-credentials"
via pkg/secrets. Provider Validator interface for per-provider schema.
pkg/push/providers/apns
- Apple Push Notification service direct provider (no Expo proxy).
- Validator + dispatcher; credentials are p8 signing key + key_id + team_id.
pkg/push/providers/ntfy/credentials.go
- ntfy credential schema (auth_token + default topic). Used both with
the public ntfy.sh and our self-hosted instance.
pkg/environments/production/installers/ntfy.go
- Self-hosted ntfy server installer. Binary, system user, hardened
/etc/ntfy/server.yml, systemd unit. Listens on 127.0.0.1:NtfyListenPort
only — Caddy is the only public path.
pkg/environments/production/installers/caddy.go
- Emit reverse_proxy block for push.<dnsZone> -> 127.0.0.1:NtfyListenPort
when operator enables ntfy on a node.
CLI: install/upgrade orchestrators learn a new "ntfy" install/preserve
phase; flag gating in install/flags.go + upgrade/flags.go.
Gateway handlers/push/credentials_handler.go
- GET/PUT/DELETE /v1/namespace/push-credentials/{provider}.
- PUT validates against provider Validator before encrypting and storing.
- GET returns a redacted view (booleans + non-secret fields only).
Push manager: provider resolution now also consults
namespace_push_credentials before falling back to YAML defaults.
Docs: core/docs/PUSH_NOTIFICATIONS.md walks through end-to-end setup.
VERSION bumped to 0.122.14.
HTTP/2 forbids the `Connection: Upgrade` and `Upgrade: websocket`
headers per RFC 7540 §8.1.2.2. With h2 advertised at the listener,
ALPN negotiates h2 for TLS-capable clients, the WS-upgrade request
arrives at Caddy with those headers stripped, and Caddy forwards a
plain HTTP/1.1 GET to the gateway. The gateway's `isWebSocketUpgrade(r)`
then returns false, the `?api_key=` / `?jwt=` query-string WS-auth
fallback never runs, and clients see 401.
RFC 8441 ("Bootstrapping WebSockets with HTTP/2") fixes this, but iOS
RN and most other mobile WS libraries don't implement it. Until they
do, h1 is the only protocol that keeps WS auth working.
Trade-off: lose h2 multiplexing on plain HTTP traffic. Acceptable for
an API gateway whose dominant workload is REST + WebSocket — neither
benefits much from h2 streams.
caddy_test.go adds a regression guard so anyone re-enabling h2 in the
listener protocols fails CI loud.
Also (separate, was uncommitted): pkg/cli/build/builder.go now reads
VERSION from the repo-root /VERSION file first, falling back to
parsing the Makefile only if absent. The previous Makefile-only path
broke after VERSION moved to /VERSION (Makefile got `$(shell cat ...)`
which the CLI builder pulled in literally).
VERSION bumped to 0.122.13.
Per-namespace rate-limit config (feature #69)
- Migration 027: new `namespace_rate_limit_config` table
(namespace PK, requests_per_minute, burst, audit metadata).
- pkg/ratelimit: Manager + RQLite ConfigStore + types. Same pattern
as the push config in bug #220's follow-up — LRU cache, invalidate
on PUT/DELETE, falls back to YAML defaults when no row exists.
- pkg/gateway/handlers/ratelimit: GET/PUT/DELETE /v1/namespace/rate-limit.
PUT requests are rejected if they exceed the operator's configured
ceiling (MaxRequestsPerMinute / MaxBurst) — tenants self-serve but
cannot raise their quota past the cap.
- pkg/gateway/rate_limiter.go: per-namespace lookup, default fallback.
- pkg/gateway/middleware.go: WS JWT middleware (middleware_ws_jwt_test.go).
- pkg/gateway/auth/service.go: refresh-token rotation hardening with
regression test in refresh_rotation_test.go.
