Jack-in fails with version 2.0.337

[cmaussan]

Jack-in is not working anymore, Calva can't connect to nREPL server whereas it is correctly launched.

; This is the Calva evaluation results output window.
; TIPS: The keyboard shortcut `ctrl+alt+o o` shows and focuses this window
;   when connected to a REPL session.
; Please see https://calva.io/output/ for more info.
; Happy coding! ♥️

; Jacking in...
; Connecting using "deps.edn" project type.
; You can make Calva auto-select this.
;   - See https://calva.io/connect-sequences/
; 
; Starting Jack-in Terminal: clojure -Sdeps '{:deps {nrepl/nrepl {:mvn/version,"1.0.0"},cider/cider-nrepl {:mvn/version,"0.28.5"}}}' -M:dev -m nrepl.cmdline --middleware "[cider.nrepl/cider-middleware]"
; Using host:port localhost:44071 ...
; Hooking up nREPL sessions ...
; Failed connecting.
; Jack-in done.
clj꞉undefined꞉>  ; Use `alt+enter` to evaluate

Downgrading to 2.0.336 fixes the issue.

ctrl+c in pseudo terminal does not really kill the repl either. A ps launched in another terminal shows the repl still up.

Thanks for reporting!

Some questions:

• If you use the command Calva: Copy Jack-in Command Line to Clipboard and use that to start the repl and then connect Calva, does that work?
• Can you reproduce this in a minimal project?
• What OS are you using?

ctrl+c in pseudo terminal does not really kill the repl either. A ps launched in another terminal shows the repl still up.

Extra interesting, it was one of the things I thought I improved with this version. I just tried in a project here:

1. After jack-in:

   % lsof -d cwd | grep 'java.*'"$PWD"                                   
   java      64431  pez  cwd    DIR   1,17      928 111060084 /Users/pez/Projects/poly-real-world
   % 
   

2. ctrl+c in the jack-in terminal:

   % lsof -d cwd | grep 'java.*'"$PWD"                                   
   %
   

It might be that the two errors are related, of course.

• I launched the repl by hand in a terminal and tried to connect to it with "connect to a running repl in your project" or "connect to a running repl, not in your project". Both did not work.
• It was failing in all my clojure projects
• Ubuntu 22.10

1. After jack-in

$ lsof -d cwd | grep 'java.*'"$PWD"
java      15651         cmaussan  cwd       DIR  253,1     4096 12072379 /home/cmaussan/code/foo

2. After ctrl+c in jack-in terminal

$ lsof -d cwd | grep 'java.*'"$PWD"
java      15651         cmaussan  cwd       DIR  253,1     4096 12072379 /home/cmaussan/code/foo

Hope that helps you.

Thanks! Does connect to a running repl in your project work in v2.0.336?

And, does ctrl+c work in 336? Thinking it could be this issue:

• The REPL process started by Calva remains when VS Code is exited #1544

(Which does not have a solution yet.)

Yes!

And, does ctrl+c work in 336? Thinking it could be this issue:

It works! (that's why I noticed it in 337)

ctrl+c in pseudo terminal does not really kill the repl either. A ps launched in another terminal shows the repl still up.

Hi again! The connection issue should be fixed in 338. Can you check if this one still is left to fix?

[cmaussan]

Hello!
Yes, the connection issue is fixed. But ctrl+c in the terminal still does not kill the repl.

Thanks. We track it here now:

• Stopping Jacked-in REPL process doesn't kill Unix Java process #2116
