`createRpcWorker` should not override `execArgv`

[mook-as]

Current behavior

I have a project that seems to blow up TypeScript because there are too many generics involved; I have to build it with node --stack-size=… so that the stack is big enough.

Note that it appears that NodeJS does not allow setting this option via NODE_OPTIONS.

However, rpc-worker#createRpcWorker currently clobbers options.execArgv if a memory limit is set, which it always is. This means that I can't pass it in on the command line.

Expected behavior

The relevant line:

fork-ts-checker-webpack-plugin/src/rpc/rpc-worker.ts

Line 32 in 0fab463

options.execArgv = [`--max-old-space-size=${memoryLimit}`];

It would be nice if that's something along the lines of:

    options.execArgv = process.execArgv.concat([`--max-old-space-size=${memoryLimit}`]);

Steps to reproduce the issue

I suppose the easiest would be:

1. Launch webpack with --stack-size=… arguments.
2. Check ps output (or equivalent) to see that the TypeScriptReporterRpcService.js processes do not have --stack-size=… in the command line. (They have --max-old-space-size=2048 instead.)

Issue reproduction repository

Sorry, I don't have a minimal test case; hopefully I have provided enough information to be clear what the issue is.

• typescript: 5.4.5
