Development Update — May 26

A refactoring-heavy day with one clear goal: make the visor config generator compile to WASM under TinyGo, so the install-command generator page can build a real config in the browser from the live flag set. That meant surgically removing net/http and encoding/json from the config-gen build graph and hand-rolling a streaming JSON serializer. Alongside, the skypty-over-skynet listener gets the fixes that make it actually start and accept connections.

Skywire: A WASM-Clean Config Generator

The install-command generator lifts skywire’s own autoconfig flag set into a browser form via a TinyGo-compiled WASM blob — so the flags shown always match the binary. To generate a config in the browser (not just assemble a command line), the config generator itself has to compile under TinyGo, which is strict about what packages it accepts. Today does that surgery.

2829 feat(visorconfig): extract schema leaf packages — V1 now WASM-clean + 2830 feat(skywireconfig): genvisor — WASM-clean visor config generator — the config schema’s leaf types are extracted into packages that don’t drag heavy dependencies, and a genvisor generator is built that compiles cleanly to WASM.

2834 refactor(visorconfig,dmsg/disc): drop net/http from WASM build graph + 2835 refactor: split json paths for WASM + 2836 refactor: purge encoding/json from WASM build graph — TinyGo unlocked + 2837 feat(genvisor): hand-rolled streaming JSON serializer for TinyGo — the two big blockers were net/http and encoding/json, both of which TinyGo struggles with. net/http is dropped from the config-gen graph entirely; encoding/json is purged and replaced with a hand-rolled streaming JSON serializer. With both gone, TinyGo is unlocked and the generator compiles. 2828 adds js/wasm build-tag stubs for netutil/skyenv, and 2826 makes the autoconfigcmd factory + keypair generation WASM-clean.

2832 feat(autoconfig): config-gen parity — every SKYENV variable now exposed + 2838 feat(autoconfigcmd): expose config-gen defaults via EnvMapping — config-gen parity: every SKYENV variable is now exposed through the generator, with defaults surfaced via an EnvMapping, and 2827 gives the flags operator-helpful descriptions. The browser form can now drive the full config surface.

Skywire: skypty Over Skynet — Make the Listener Work

Yesterday’s management-over-skynet work needed the pty’s skynet listener to actually function.

2846 fix(visor): dmsgpty skynet listener never started due to init ordering + 2847 fix(visor): dmsgpty skynet listener silently rejects route-group conns — two bugs that made the skynet pty path a no-op: the listener was never started because of initialization ordering, and even when reached it silently rejected route-group connections. Both fixed — pty over the routed overlay now actually accepts.

2841 feat(dmsgpty): add –scheme flag to bypass MultiDialer chain — a --scheme flag lets the operator pin the transport (e.g. force skynet, or force dmsg) instead of letting the MultiDialer chain choose — useful when one path is flaky and you want to exercise the other deliberately.

Skywire: dmsg-Discovery Self-Publish (and a Revert)

A short back-and-forth on how services register themselves: 2843 fix(dmsgdisc): self-publish own entry so DMSG-first actually works was merged, then 2844 reverted it, and 2845 fix(dmsgclient): stop services self-publishing via fallback wrapper settled the question — services shouldn’t self-publish through the fallback wrapper. The honest record of working out the right registration path.

Skywire: Misc

• 2839 ci: enable Windows arm64 MSI build — the Windows MSI matrix gains arm64.
• 2842 fix(hypervisor): refresh summary cache from RPC goroutine, not select arm — the summary cache refresh moves off the actor’s select arm into its own goroutine, so a slow refresh doesn’t stall the hypervisor’s event loop.
• 2840 fix(visor): quiet rpc_bridge accept-loop log spam during shutdown + 2823 fix(cmdutil): BootstrapDmsg uses HTTP discovery for client entry lookups — log-spam cleanup on shutdown, and a bootstrap fix for client-entry lookups.
