Summary
On Windows with real-time antivirus, 4.0.13 can fail to start the tunnel with
spawn EBUSY.node-stream-zip'sextract()resolves before the extracted binary's file handle is closed, so the binary is spawned while it's still open for writing.Change
lib/tunnel_binary.js: stream the binary entry into our own write stream and wait for'close'beforechmod+ spawn.latest4.0.14, add 4.0.13/4.0.14 tosupportedVersions, sync FreeBSD hashes with the hosted config.Verification
With the delayed close, 4.0.13 fails on Windows (
EBUSY) and Ubuntu (ETXTBSY). This branch passes on all OS/Node combinations.🤖 Generated with Claude Code
