* tools: make code cache and snapshot deterministicBen Noordhuis2019-08-191-0/+5
| | | | | | | | | | | | | | | | Use a fixed random seed to ensure that the generated sources are identical across runs. The final node binary still reseeds itself on start-up so there should be no security implications caused by predictable random numbers (e.g., `Math.random()`, ASLR, the hash seed, etc.) Fixes: https://github.com/nodejs/node/issues/29108 PR-URL: https://github.com/nodejs/node/pull/29142 Reviewed-By: Gus Caplan <me@gus.host> Reviewed-By: Colin Ihrig <cjihrig@gmail.com> Reviewed-By: Anna Henningsen <anna@addaleax.net>

* tools: implement mkcodecache as an executableJoyee Cheung2019-04-161-0/+62
This patch implement a mkcodecache executable on top of the `NativeModuleLoader` singleton. This makes it possible to build a Node.js binary with embedded code cache without building itself using the code cache stub - the cache is now initialized by `NativeModuleEnv` instead which can be refactored out of the mkcodecache dependencies.
