M4: canonical-opencode runtime updater — managed install + full adopt gate (live-drill proven) - #479
Conversation
…, full adopt gate, live-drill proven M4 of #451: the runtime updater that keeps users on current canonical opencode (anomalyco/opencode) without a VSIX release. opencode_updater.ts (vscode-free): managed install at ~/.amico/opencode/canonical/versions/<v>/ with an atomically swapped current symlink. THE ADOPT GATE (a candidate failing ANY stage is never adopted; last-known-good is never deleted): 1. sha256 vs the GitHub release-asset digest — digest ABSENCE refuses adoption (never verify-less) 2. --version prints the candidate version 3. boot smoke on an ephemeral port (isolated HOME/DB/config) — health poll, /config trigger (instance bootstrap is lazy in this build; found via the live drill), and the plugin-registration assert: the stamp plugin must write its file at module load 4. DB-compat probe: consistent copy of the live chat DB via the sqlite backup API (never a mid-write file copy), booted against with a fresh per-probe stamp assert 5. atomic adopt: same-fs rename + symlink swap; prune keeps the newest two (current + rollback) opencode_updater_wiring.ts: first-activation bootstrap (never blocking), 24h timestamp-gated checks, hourly timer, Amicode: Update canonical opencode command. Terminal PATH: managed canonical FIRST (D2), with an idempotent opencode-amicode shim → the vendored fork binary so fleet surfaces stay reachable. LIVE DRILL (scripts/updater_live_drill.mts, real release, real network, real 1.2GB live DB): adopted v1.18.19 end-to-end in 13.8s. Unit suite 14/14 (every refusal path + atomicity + pruning); full suite 1196/1196; typecheck clean.

Add darwin-x64 and surface unmapped platforms.
platformAsset maps only three keys. On darwin-x64 (Intel macOS) and win32 it throws. checkForUpdate calls it inside the catch-all at Line 160, so the throw becomes {kind:"current"}. The user gets a permanent silent no-update state.
The effect reaches activation: in packages/extension/src/opencode_updater_wiring.ts (Lines 112-118) managedBinary() stays undefined, so bootstrap runCycle re-runs on every activation and downloads nothing.
Resolve the platform mapping before the try block, or return a distinct kind so the caller can log an actionable message.

Keep the last-known-good install when re-adopting the version currently selected. The adoption path removes versions/<candidate.version> before the --version, boot, plugin, and database gates run. If any gate fails, current becomes dangling and the managed binary disappears. Move removal until immediately before the final rename, and add a regression test that adopts once, fails a second adoption, and verifies that current and managedBinary remain valid.

🧩 Analysis chain
🌐 Web query:
opencode serve --port 0 ephemeral port hostname option
💡 Result:
When using the opencode serve command, setting --port 0 instructs the server to listen on an ephemeral, randomly assigned available port [1][2][3]. Regarding your query about the hostname option: The --hostname flag defines the interface or address the server binds to [1][2]. The default value is 127.0.0.1 [4][5][3]. If you need the server to be accessible from other machines on your network, you can set --hostname to 0.0.0.0 [1][2]. Additionally, if you enable mDNS discovery using the --mdns flag, the default hostname is automatically set to 0.0.0.0 to facilitate network-wide visibility [3]. You can override these defaults by passing specific values via the CLI flags or by configuring them in your global configuration file located at ~/.config/opencode/config.json [1][3]. CLI flags will always take precedence over settings defined in the configuration file [1].

site:github.com/anomalyco/opencode "port 0" "serve"
💡 Result:
In network programming, requesting "port 0" instructs the operating system's networking stack to automatically assign an available, ephemeral port to the socket [1][2][3]. This mechanism is commonly used by developers when they want to run a server or client without needing to specify or hardcode a specific port number, avoiding "address already in use" (EADDRINUSE) errors [1][4]. Once the socket is bound and listening, the application can query the OS to determine which port was actually assigned [2][5]. While "port 0" is a standard convention in most operating systems and networking libraries (such as those in Node.js, Bun, or Python), some specific software applications may implement custom behavior when presented with port 0 [2][5]. For example, in certain CLI tools like opencode, the logic has been specifically configured to attempt binding to a preferred port (such as 4096) first, and only if that is unavailable does it fall back to using port 0 to dynamically select any other free port [2][3][5]. In summary: - General Networking: Port 0 acts as a wildcard that tells the OS to choose any available free port [1][4]. - Application-Specific Logic: Some applications may treat "port 0" as an instruction to follow custom logic, such as prioritizing a specific default port before falling back to the OS-assigned dynamic port [2][5].

anomalyco opencode serve --port 0 prints listening URL assigned port stdout
💡 Result:
When you run the command opencode serve --port 0, the OpenCode server does print the assigned listening URL to stdout [1]. The implementation explicitly logs this information upon startup: console.log(opencode server listening on http://${server.hostname}:${server.port}) [1] In OpenCode's network configuration, passing --port 0 is the designated method to trigger the auto-assignment of a free port [2][3][4]. If the port is set to 0, the system defaults to attempting to use port 4096 first, and if that is unavailable, it selects an arbitrary free port [5][2][4]. Note that while this behavior is standard, there are documented scenarios where headless server processes may fail to output this information if the process is spawned in a way that interferes with standard I/O (such as detaching with stdin ignored without a TTY), causing silent exits [6]. However, under normal terminal operation, the listening URL is printed to stdout as expected [1].

The relevant result is the OpenCode SDK server implementation:

- It detects readiness when output begins with:

💡 Result:
I couldn’t find that exact test file in GitHub search. The relevant current behavior is:
- When
port: 0is passed, OpenCode first attempts port 4096, then falls back to an OS-assigned free port if 4096 is unavailable. (github.com) - The CLI prints the selected address as
opencode server listening on http://<hostname>:<port>. (github.com)
So the expected output for a port: 0 listen test is likely a dynamically resolved URL, commonly port 4096 unless occupied.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Both poll loops spin without a delay on non-200 responses.
The 250 ms sleep sits only in the catch branch. Once the server accepts connections, fetch resolves. Any non-200 status, for example 401 or 503 during startup, takes the success path, skips the sleep, and re-enters the loop immediately.
The result is a hot loop that issues continuous HTTP requests for the full bootTimeoutMs window, which defaults to 30 s. It burns CPU on the extension host and loads the starting probe server. The same defect exists in the /config loop at Lines 383-390.
Add the delay after each attempt, and bound each request so a hung connection cannot exceed the deadline.

Use the managed binary for direct opencode terminals.
Lines 66-70 only affect shell PATH lookup. When the command receives an opencode argument, the later shellPath = vendorBin assignment bypasses PATH and always starts the vendored fork. This conflicts with the managed-canonical-first terminal contract after adoption.

Handle rejected runCycle promises.
checkForUpdate() catches fetch and parsing failures, but adoptRelease() can still reject during staging setup or cleanup. The background and manual call sites attach no rejection handler. Add shared .catch(...) handling that logs background failures and reports manual failures to the user.

Update the runCycle call sites in checkForUpdate and the manual update flow to
attach shared rejection handling. Log failures from background runs, while
reporting manual-run failures to the user, including rejections from
adoptRelease staging or cleanup; preserve the existing success handling and

Part of #451 (M4; not closing — M2/M3/M5 remain).
What's here
The runtime updater that keeps users on current canonical opencode without waiting on a VSIX release — the machinery behind "automatically the most up-to-date opencode."
src/opencode_updater.ts(vscode-free): managed install at~/.amico/opencode/canonical/versions/<v>/with an atomically swappedcurrentsymlink. The adopt gate — any stage fails, the candidate is refused and last-known-good survives untouched: sha256 vs the GitHub API asset digest (digest absence refuses adoption, per the spec),--versionprobe, boot smoke on an isolated ephemeral port, the plugin-registration assert (stamp plugin must write at module load — validated on a stock binary in M0), and the DB-compat probe (consistent copy of the live chat DB via the sqlite backup API — never a mid-write file copy — booted against, with a fresh stamp assert per probe). Atomic adopt via same-fs rename + symlink swap; prune keeps the newest two versions.src/opencode_updater_wiring.ts: first-activation bootstrap (fire-and-forget — activation never blocks on a download), 24h timestamp-gated checks + hourly timer, and the Amicode: Update canonical opencode command.opencodeto the managed canonical binary first, with an idempotentopencode-amicodeshim to the vendored fork so fleet/guard surfaces stay reachable.scripts/updater_live_drill.mts: the drill harness — real release, real network, real DB.The live drill (the part that matters)
Two consecutive runs against the real v1.18.19 release: adopted end-to-end in 13.8–15.2s — check (0.2s), 46 MB download, digest verify, extract, version probe, boot + plugin stamp, and the DB-compat probe against a consistent copy of the real 1.2 GB live chat DB. The drill also caught a real behavior: this build's
servecreates its instance lazily (first instance-bearing request), so the gate now triggers/configbefore asserting the stamp — without it the assert would hang forever on a healthy-looking server.Verification
Unit suite 14/14 (every refusal path — digest absence, sha mismatch keeps LKG current, version mismatch, boot failure — plus atomicity, pruning, re-adopt idempotence, consistent-copy roundtrip); full suite 1196/1196; typecheck clean; live drill ×2 adopted.
