Below are checklists indicating the progress of these issues & pull requests.
A checkmark indicates it is resolved (or merged).

This issue encompasses the following issues:

• Chunked stdout/stderr drops writes if terminated early. Chunked stdout/stderr drops writes if terminated early. #784
• Interleaved stdout/stderr on terminals (TTYs)
  • Part of: stdio buffered writes (chunked) issues & process.exit() truncation stdio buffered writes (chunked) issues & process.exit() truncation #6456
• Missing or truncated error message Missing or truncated error message #6867

And the following pull requests:

• process: flush stdout/stderr upon process.exit() process: flush stdout/stderr upon process.exit() #6773
• tty: set the handle to blocking mode tty: set the handle to blocking mode #6816
• tty: use blocking mode on OS X tty: use blocking mode on OS X #6895
• unix: add uv_flush_sync unix: add uv_flush_sync libuv/libuv#876
• unix,stream: fix getting the correct fd for a handle unix,stream: fix getting the correct fd for a handle #6838
  • Should be backported to v4.x (and maybe v5.x)

The current item in focus is:
n/a

The TTY (Terminal) issues have been resolved. Pipes still remain a problem.

This pr was a result of the discussion in #6968 to better track all the efforts going on here.

[EDIT by @Trott: Did some edits around the 6773 PR checklist item, but undid them]

[Fishrock123]

Current plan is to make a release candidate (today/tomorrow) as discussed in #6934 with the OS X patch from #6895 to fix the largest issue (OS X stdio interleaving to TTYs) asap.

You can add this one to the list:

#6867 Missing or truncated error message

It's a variation of the process.exit() stdio truncating problem but with uncaught exceptions.

Edit: reproduced on node 5.x on Linux. Same issue likely exists on node 4.x.

This related merged PR for process.stdout._handle.fd should also be mentioned here for completeness:

unix,stream: fix getting the correct fd for a handle #6838

It ought to be back ported to node 5.x and 4.x.

[Fishrock123]

No guarantees on v5.x since it's now in critical-maintinence-only mode, but we'll try to get in v4.x soon.

[Fishrock123]

I have an RC up at https://nodejs.org/download/rc/v6.2.1-rc.1/ that should fix the OS X problems.
Please test.

@Fishrock123

Qix- is missing the Overall/Read permission

[Fishrock123]

@Qix- Are you getting that attempting to access the directory, or the files themselves?

(or is node making that error?)

@Fishrock123 Works now, not sure what changed. :) I'll give it a try.
