fix: forward termination signals to the CLI binary - #462
Conversation
The npm launcher spawned the Ory CLI binary with spawnSync and installed no signal handlers, so a SIGINT/SIGTERM/SIGHUP delivered to the launcher ended the launcher alone and orphaned the binary. `ory tunnel` and `ory proxy` create a temporary Ory Network API key and delete it in their graceful shutdown handler; an orphaned process never runs that handler, so the key lingered until its expiry and the running proxy kept serving. Spawn the binary asynchronously and forward SIGINT, SIGTERM and SIGHUP to it, then exit with the child's status — or, when the child was killed by a signal, re-raise that signal on the launcher so callers observe the same termination as before. This restores the behaviour callers had when they ran the binary directly. Add npm/run.test.js (node:test) covering argument passthrough, exit-status propagation, signal forwarding, signal-based termination, and the missing-binary error, wired into CI as the test-launcher job. The test file is excluded from the published package by the existing `files` allowlist.

📝 WalkthroughWalkthroughThe npm launcher now starts the platform CLI asynchronously, forwards termination signals, propagates exit status, and reports startup errors. New tests cover these behaviors. A Node.js 22 CI job runs the launcher tests. ChangesLauncher lifecycle
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new CI job may receive broader repository token permissions than it needs because read-only contents access is not declared explicitly.

GitHub Actions GITHUB_TOKEN permissions unspecified workflow and job-level permissions default contents read documentation
💡 Result:
The GITHUB_TOKEN permissions in GitHub Actions are determined by a hierarchical configuration process that prioritizes the principle of least privilege [1][2]. Default Permissions The initial permissions for the GITHUB_TOKEN are determined by the default settings established at the enterprise, organization, or repository level [3][4]. Admins can configure these defaults in the repository or organization settings under Actions > General [5][6]. There are typically two modes: 1. Permissive: Provides broad read and write access to most scopes [2][6]. 2. Restricted: Provides read-only access to repository contents and packages [5][2]. Workflow and Job-Level Overrides You can explicitly define or modify these permissions within your workflow file using the permissions key [7][2]. This configuration can be applied at two levels: 1. Workflow level: Specify the permissions key at the top level of the YAML file to apply them to all jobs in that workflow [3][8]. 2. Job level: Specify the permissions key within a specific job (jobs.<job_id>.permissions) to override or refine permissions for that job only [9][3]. Behavior of the Permissions Key When you use the permissions key, any permission not explicitly included in your list is automatically set to none [2]. For example, if you define only contents: read, all other scopes (such as packages or issues) will be set to none, even if they were enabled by the repository-level default [9][2]. Special Case: Pull Requests Regardless of your configured settings, workflows triggered by pull requests from forked repositories are subject to additional security restrictions. In these cases, the GITHUB_TOKEN is automatically downgraded to read-only mode to prevent unauthorized access or modification, unless the repository explicitly permits sending write tokens to workflows from pull requests [3][2][8]. Summary of Precedence The effective permissions for a job are calculated in the following order: 1. Repository/Organization/Enterprise default settings [3][4]. 2. Workflow-level permissions (if specified) [3][4]. 3. Job-level permissions (if specified) [3][4]. 4. Automatic restrictions applied to pull requests from forks [3][8].

Summary
The
@ory/clinpm launcher (npm/run.js) spawned the platform binary withspawnSyncand registered no signal handlers. ASIGINT/SIGTERM/SIGHUPdelivered to the launcher therefore ended the launcher alone and left the Ory CLI binary running as an orphan.This matters for
ory tunnelandory proxy: both mint a temporary Ory Network API key and delete it in their graceful-shutdown handler. An orphaned binary never runs that handler, so the key lingers until its 12h expiry and the proxy keeps serving after the caller thinks it stopped. Scripts that backgroundpnpm exec ory tunnel …and laterkillthe job — for example the Ory docs code-example E2E suite — hit exactly this.What changed
npm/run.jsnow spawns the binary asynchronously and forwardsSIGINT,SIGTERMandSIGHUPto it. It exits with the child's status, or — when the child was terminated by a signal — re-raises that signal on itself, so callers observe the same termination as running the binary directly.npm/run.test.js(node:test, no new dependencies) covers argument passthrough, exit-status propagation, signal forwarding, signal-based termination, and the missing-binary error. It builds a stand-in binary and thenode_moduleslayout npm produces, so it exercises the realrequire.resolvepath. The file is excluded from the published package by the existingfilesallowlist.test-launcherjob runningnpm run test:launcher.Notes
spawn/spawnSyncdo not create a process group, so this restores signal delivery through a single launcher hop — which is what a directpnpm exec ory …(one pnpm process) uses. It does not change behaviour for intermediaries that swallow signals themselves.🤖 Generated with Claude Code
