Not working through the terminal nor IntelliJ IDEA Go plugin

Temporarily solved the problem by removing new Command Line Tools
$ sudo rm -rf /Library/Developer/CommandLineTools

then go to page https://developer.apple.com/download/more/
download and install previous version

Command Line Tools (macOS 10.13) for Xcode 9.1 - Dec 6, 2017

Enjoy!

@aarzilli Do you need more info? Is there any workaround or a way to troubleshoot this issue?

pablomolnar picture pablomolnar on 27 Nov 2017

do you get the window asking for a password for debugserver?

aarzilli picture aarzilli on 27 Nov 2017

What happens if you run /Library/Developer/CommandLineTools/Library/PrivateFrameworks/LLDB.framework/Versions/A/Resources/debugserver <path to a go executable>?

aarzilli picture aarzilli on 27 Nov 2017 
$ /Library/Developer/CommandLineTools/Library/PrivateFrameworks/LLDB.framework/Versions/A/Resources/debugserver localhost:33445  ./hello
debugserver-@(#)PROGRAM:debugserver  PROJECT:debugserver-900.0.57
 for x86_64.
Listening to port 33445 for a connection from localhost...

$ $GOPATH/bin/dlv exec ./hello
could not launch process: EOF

But are you getting the password prompt?

You should change the variable logGdbWire to true in $GOPATH/src/github.com/derekparker/delve/pkg/proc/gdbserial/gdbserver.go:86, recompile and copy the output (or capture the traffic between debugserver and dlv with wireshark or similar).

aarzilli picture aarzilli on 27 Nov 2017

Not getting password prompt, will try to recompile and send output.

pablomolnar picture pablomolnar on 28 Nov 2017

If you are not getting the password prompt then that's likely the problem, how are you running dlv? A normal terminal or a ssh connection?

aarzilli picture aarzilli on 28 Nov 2017

I'm running dlv through Intellij IDEA Go plugin, but just to simplify I'm getting the same error using my terminal. No ssh.

Wondering why dlv should require root privileges, I believe I never had to prompt a password

pablomolnar picture pablomolnar on 28 Nov 2017

I doesn't require root privileges but debugserver will still want you to enter your password to debug any process.

aarzilli picture aarzilli on 28 Nov 2017

If you do recompile you should also turn on the showLldbServerOutput flag (same file).

There you go

what happens if you comment out lines $GOPATH/src/github.com/derekparker/delve/pkg/proc/gdbserial/gdbserver.go:292 through 296:

    if addr, err := p.conn.allocMemory(256); err == nil {
        if _, err := p.conn.writeMemory(uintptr(addr), p.loadGInstr()); err == nil {
            p.loadGInstrAddr = addr
        }
    }

Now I'm able to get to delve prompt (Type 'help' for list of commands.). Still investigating why using the new dlv binary is not working in IntelliJ IDEA

pablomolnar picture pablomolnar on 28 Nov 2017

I think IntelliJ IDEA uses its own dlv binary saved somewhere, you would have to replace that. I'm interested in hearing about further testing of this change.

I got the same issue: https://github.com/derekparker/delve/issues/1153
Still got "could not launch process: EOF" after tried all above.

How to Solve this Issue???

sychoo picture sychoo on 30 Mar 2018

To anyone having this problem, somebody should do this:

You should change the variable logGdbWire to true in $GOPATH/src/github.com/derekparker/delve/pkg/proc/gdbserial/gdbserver.go:86, recompile and copy the output (or capture the traffic between debugserver and dlv with wireshark or similar).

@aarzilli I tried just now,it is unuseful. But thanks

@iharsuvorau this is a crash in debugserver when reading the registers of a thread, it needs to be reported to LLVM/Apple, nothing I can do about it. However you are running 10.13.3 and the others seem to encounter this problem after upgrading to 10.13.4

After update command line tools to version 9.3 (Mar 30 2018) same problem..

Temporarily solved the problem by removing new Command Line Tools
$ sudo rm -rf /Library/Developer/CommandLineTools

then go to page https://developer.apple.com/download/more/
download and install previous version

Ran into this problem today. @otRock is on the right track, but I imagine a more correct download would be the

Command Line Tools (macOS 10.13) for Xcode 9.2

Looks like, at least on my system, that /Library/Developer/CommandLineTools was updated on April 1st (how appropriate). I'm about to reboot to install 10.13.4 so I'm hoping that this old version of command line tools will not magically disappear again.

datochan picture datochan on 6 Apr 2018

The fix proposed by @otRock works well, but only temporarily for me. I cleaned / re-installed the tools, worked a bit... and then left my PC for a couple hours to come back to the debugger quitting unexpectedly with the EOF error again.

Can't wait for a patch!

mabruneau picture mabruneau on 6 Apr 2018

Tried reinstalling the tools for Xcode 9.3, but still see the same error. Went back to Xcode 9.2 and everything works correctly.

ann-kilzer picture ann-kilzer on 9 Apr 2018

@mabruneau Did you verify that the command line tools weren't updated automatically once again?
I've had to reinstall the 9.2 command line tools a second time (so far) after they mysteriously updated themselves.

FYI, I installed the workaround a couple days ago, and it looks like at some point my software auto-updated forcing me to implement the workaround again.

jicki picture jicki on 17 Apr 2018

@markeissler you are right, since I disabled auto-update, everything has been stable. I also installed macOS 10.13.4 successfully, without messing up the CL tools. That being said, not clear to me why I have multiple versions... 10.13 seems to be using 9.2...

You may have to uninstall dlv and install it manually as per instructions

Reinstall the dlv package works for me. I run the following commands and the golang works well after

I just optimistically tried yesterday's release of Command Line Tools (macOS 10.13) for Xcode 9.4 and found it didn't fix the issue. Installing the Xcode 9.2 version fixed the problem for me.

Good news, today I've received an update for Command Line Tools (macOS High Sierra version 10.13) beta 1 for Xcode, version 10.0 and dlv works fine after the update 🎉

I'm going to close this bug. The cause of the original bug report (debugserver crashing on memory allocation) was never found and there hasn't been any other feedback.

Over time the thread was contaminated by reports of an entirely different bug (debugserver crashing on the 'g' command). This second problem received a temporary workaround in delve and was later fixed by llvm.
