Delve: proc: Fix Launch race condition on OSX

[derekparker]

The current implementation of fork/exec'ing the child process, and then trying to parse information out of the running process seems to be racy. It seems the child process is not fully initialized when we try and parse information from it.

We seem to get errors similar to:

could not launch process: Could not determine version number: could not read string len could not read memory

I am working on a fix for this, I hope to have up soon.

Hi
I face some similar issue in mac
when start debug by dlv, it only work sometimes.

I trace syscall in dlv process, it will received the request like create 5 break point and then continue.
created breakpoint: created breakpoint: created breakpoint: created breakpoint: created breakpoint: continue

I turn on dlv's logger
when working properly, log will look like
created breakpoint: created breakpoint: created breakpoint: continue

but sometimes the same commands but the sequence will become
continue
and block all the other requests.

seems like the command's sequence is not always equal to execution sequence.
then intellij will halt there.

Currently working on this issue as we speak. I have some OSX fixes and
general refactoring / code cleanup patches I'll be submitting soon.

Hello, any progress on this issue?
I am experiencing the same problem with my IntelliJ IDE on my Mac (go development)
Even a workaround should be enough until it's fixed

Let me know if I can help with testing

Thanks for your work

This should be fixed on master.
