Threads Signal Handling Hack

[CMCDragonkai]

Specification

Any entrypoint to the Polykey-Desktop application must do this at the beginning:

/**
 * Hack for wiping out the threads signal handlers
 * See: https://github.com/andywer/threads.js/issues/388
 * This is done statically during this import
 * It is essential that the threads import here is very first import of threads module
 * in the entire codebase for this hack to work
 * If the worker manager is used, it must be stopped gracefully with the PolykeyAgent
 */
import 'threads';
process.removeAllListeners('SIGINT');
process.removeAllListeners('SIGTERM');

If it is expected that process context needs to import PolykeyAgent or really any transitive import of @matrixai/db or threads.

When the signal handlers are removed from upstream, this hack can be removed from Polykey and Polykey-Desktop.

Additional context

• Implementing BIP39 recovery, Unattended Bootstrap and Agent Start and Status Polykey#283 (comment) - where this problem was discovered
• Should really not install signal handlers that call process.exit with no way to opt out andywer/threads.js#388 - Upstream issue
