• File internal/sync/nethttp_tinygo.go — part of check-in [0650171d55] at 2026-10-23 21:25:20 on branch main — feat(wasm): build the whole public API with TinyGo

  go-libfossil compiled for js/wasm only with the standard toolchain, whose output is about 16 MB, too large to ship with a page or an edge function. Three standard-library features TinyGo lacks kept it from building there: http.ErrUseLastResponse and net.DNSError in the sync client, and os.SameFile in checkout-marker recovery.

  Each now sits behind a tinygo build tag. Under TinyGo a sync redirect ends the request with an error instead of being followed, DNS failures are not classified as transient, and two names of one checkout marker are reported as ambiguous rather than paired; the standard build is unchanged.

  examples/tinygo exercises the whole public API, sync and signing included. Built with TinyGo 0.43 and wasm-opt -Oz it is 3.83 MB raw and 1.40 MB gzipped, against 16.1 MB and 4.06 MB from the standard toolchain. A new CI job builds it with TinyGo on every change.

//go:build tinygo

package sync

import "errors"

// errStopRedirect: TinyGo's net/http has no ErrUseLastResponse, so a redirect
// ends the request with this error rather than being followed. A TinyGo
// build normally syncs through a transport its host supplies, not PostXfer.
var errStopRedirect = errors.New("sync: redirect not followed under TinyGo")

// dnsFault: TinyGo's net package has no DNSError, so no failure is classified
// as name resolution; the other network checks still apply.
func dnsFault(error) (transient, ok bool) { return false, false }
