* feat: rebuild plugin pages with host rendering and native settings * fix(plugins): contain host-view errors, isolate editing, and migrate fixtures * fix(plugins): migrate remaining permission fixture hosts
Read one disposable database row
This browser plugin tests the generic network.byte-streams feature and exact
network.stream permission. The database protocol and fixed SELECT query live
only in this example. The host transports bounded bytes.
Prepare a package for one private IPv4 fixture endpoint:
npm run build:plugin-runtime-deps
node examples/plugins/database-minimal/prepare.mjs tcp://10.77.0.20:3306 /tmp/database-example.ncpkg
node packages/plugin-cli/dist/cli.js validate /tmp/database-example.ncpkg
sha256sum /tmp/database-example.ncpkg
The address above is a packaging example. Preparation does not connect to it. Use the actual disposable fixture address for native testing. A different endpoint produces a different manifest, bundle, and package hash.
Import the package through Settings > Plugins, enable it, and open Disposable
database example. Enter only the fixture's session credentials. Deny the first
endpoint prompt, then retry and grant that exact endpoint. A successful read
shows synthetic stream result. Cancel stops the active operation.
The fixture must be reachable at a private address belonging to a different machine or container, rather than an address assigned to the app's machine. Loopback, the app machine's interface addresses, and mapped aliases remain blocked. Do not replace the endpoint with a local SSH forwarding address.
The example supports protocol 4.1 and mysql_native_password over plain TCP.
Its server account needs only SELECT on plugin_demo.example_result. The query
is SELECT value FROM plugin_demo.example_result LIMIT 1. Server grants enforce
read-only access. The example does not support database TLS or STARTTLS.
Credentials are session-only and are not written to plugin settings, logs, or secrets. JavaScript does not guarantee memory zeroization. The plugin has no query editor, schema browser, or connection manager.
Follow the native handoff for fixture prerequisites, screenshots, video, cancellation, and cleanup.
