process.title don't change process name #28945
Description
Activity
/cc @nodejs/platform-macos since on Linux this seems to work
I use
nvm, my steps to reproduce:nvm use v10.15.3 && / node -e "process.title = 'process.title test'; process.stdin.resume();"
nvm use v10.16.1 && / node -e "process.title = 'process.title test'; process.stdin.resume();"
Can I ask you to check to see if the current Node.js 12.x release works? Like to see if this regression is specific to 10.x or not.

I can reproduce the issue in 12.0.0 and 12.7.0. Like original reporter, I'm seeing the problem in 10.16.1 but not in 10.15.3. I also see the problem in 10.16.0.
8.16.0 does not have the bug.
So, to summarize for supported release lines on macOS:
- All 12.x are affected.
- 10.16.0 and newer are affected. 10.15.3 and earlier are not affected.
- All 8.x are not affected.
Sounds like it could be libuv related based on the Node.js versions affected. Node.js 10.16.0 bumped libuv from 1.23.2->1.28.0.
Windows also appears to work as expected
Maybe libuv/libuv@00c6b16#diff-60fd60fae228080a06862eae92a6e25 which came with libuv 1.24.0?
git bisectconfirms that this bug was introduced with the upgrade to libuv 1.24.0 in 9cef7b8. I suppose the thing to do is open an issue in the libuv repository. @nodejs/libuv- added 2 commits that reference this issue
on Aug 3, 2019 I can confirm that libuv/libuv@00c6b16 is responsible (but don't ask me why.) I've opened a revert in libuv/libuv#2405.

@coreybutler Can you file a new issue and link back to this one?
