Ping @addaleax if you want to take a look, but it should be pretty safe to land since it's just internal refactoring |
This patch split part of the bootstrappers into three files: - `lib/internal/process/main_thread_only.js`: contains bootstrappers that can only be run in the main thread, including - `setupStdio` for the main thread that sets up `process.stdin`, `process.stdout`, `process.error` that may interact with external resources, e.g. TTY/File/Pipe/TCP sockets - `setupProcessMethods` that setup methods changing process-global states, e.g. `process.chdir`, `process.umask`, `process.setuid` - `setupSignalHandlers` - `setupChildProcessIpcChannel` that setup `process.send` for child processes. - `lib/internal/process/worker_thread_only.js`: contains bootstrappers that can only be run in the worker threads, including - `setupStdio` for the worker thread that are streams to be manipulated or piped to the parent thread - `lib/internal/process/per_thread.js`: contains bootstrappers that can be run in all threads, including: - `setupAssert` for `process.assert` - `setupCpuUsage` for `process.cpuUsage` - `setupHrtime` for `process.hrtime` and `process.hrtime.bigint` - `setupMemoryUsage` for `process.memoryUsage` - `setupConfig` for `process.config` - `setupKillAndExit` for `process.kill` and `process.exit` - `setupRawDebug` for `process._rawDebug` - `setupUncaughtExceptionCapture` for `process.setUncaughtExceptionCaptureCallback` and `process.hasUncaughtExceptionCaptureCallback` Hopefully in the future we can sort more bootstrappers in `boostrap/node.js` into these three files and further group them into functions that can be run before creating the snapshot / after loading the snapshot. This patch also moves most of the `isMainThread` conditionals into the main bootstrapper instead of letting them scattered around special-casing different implementations.

The first commit is from #21377
This patch split part of the bootstrappers into three files:
lib/internal/process/main_thread_only.js
: contains bootstrappersthat can only be run in the main thread, including
setupStdio
for the main thread that sets upprocess.stdin
,process.stdout
,process.error
that may interact with externalresources, e.g. TTY/File/Pipe/TCP sockets
setupProcessMethods
that setup methods changing process-globalstates, e.g.
process.chdir
,process.umask
,process.setuid
setupSignalHandlers
setupChildProcessIpcChannel
that setupprocess.send
forchild processes.
lib/internal/process/worker_thread_only.js
: contains bootstrappersthat can only be run in the worker threads, including
setupStdio
for the worker thread that are streams to bemanipulated or piped to the parent thread
lib/internal/process/per_thread.js
: contains bootstrappersthat can be run in all threads, including:
setupAssert
forprocess.assert
setupCpuUsage
forprocess.cpuUsage
setupHrtime
forprocess.hrtime
andprocess.hrtime.bigint
setupMemoryUsage
forprocess.memoryUsage
setupConfig
forprocess.config
setupKillAndExit
forprocess.kill
andprocess.exit
setupRawDebug
forprocess._rawDebug
setupUncaughtExceptionCapture
forprocess.setUncaughtExceptionCaptureCallback
andprocess.hasUncaughtExceptionCaptureCallback
Hopefully in the future we can sort more bootstrappers in
boostrap/node.js
into these three files and further groupthem into functions that can be run before creating the
snapshot / after loading the snapshot.
This patch also moves most of the
isMainThread
conditionalsinto the main bootstrapper instead of letting them scattered around
special-casing different implementations.
