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.
