Tracking Issue: process.binding to internalBinding

[jasnell]

Moving from process.binding() to internalBinding() will be a significant effort. There are hundreds of process.binding() uses inside core and many many userland references. It's going to take a while to convert everything.

TODO

• inspector (this one is quite non-trivial... will require additional thought)

updated to include all usage of NODE_BUILTIN_MODULE_CONTEXT_AWARE

[jasnell]

I've got uv in progress now

[devsnek]

@ChALkeR would it be possible to get info about the relative usage of all of these? i'm assuming there are some like serdes we can kill right away and others like util that will take longer.

[jasnell]

I tried doing zlib but it broke npm.
I tried doing config but there's a buffer test that isn't feasible if config is moved. Planning to refactor

[maclover7]

Just double checking, should all migration PRs should be marked as semver-major?

[jasnell]

Unfortunately that's likely the best thing.

[jasnell]

For some of this it's likely going to be quite tricky to have a proper migration strategy in place given that moving something over to internalBinding() means that the process.binding() version just stops working. We're going to have to take it very slow and work on migrating the bits with the smallest immediate impact and working up from there.
