dirac + cljs-repl max call stack exceeded?

Tái hiện vấn đề từ branch gen-cljs dirac-start-browser-repl-max-call-stack-exceeded được liên kết, bắt đầu từ dòng 40 của build.boot và tác vụ dev của Boot. Chạy boot dev, boot repl -c, sau đó (start-repl), tải lại localhost:3000 và kiểm tra stack bootstrap của clojure.browser.repl. Hoàn tất khi xác định được liệu tích hợp Dirac có gây ra đệ quy hay không và khôi phục được việc đánh giá ClojureScript hoạt động trong CIDER/Emacs.

Do feel free to shoot this down if this is not an issue with dirac, rather some of the other dependencies, a combination, or a too complex setup to dig into 😄

In an attempt to see how good of a cljs stack I could come up with, I was trying out dirac in combination with a few other tools along with boot; dirac, boot-cljs-devtools, boot-cljs-repl, boot-cljs, boot-http, boot-reload

This branch holds a repro https://github.com/torgeir/gen-cljs/tree/dirac-start-browser-repl-max-call-stack-exceeded.

What I'm seeing is by running boot dev (after adding (dirac)) to fire everything up, and connecting to it in another terminal window with boot repl -c - it connects nicely

The repl still seems to be working

but the dirac console also complains

Is this a problem? I don't know. The issue I am having with it is that my emacs instance is no longer able to run cider-connect followed by (start-repl) and have a working repl inside emacs to evaluate cljs code on the go.

I am running boot with the following ~/.boot/profile.boot in place to have things working inside emacs.

(def v-tools-nrepl "0.2.13")
(def v-cider-nrepl "0.17.0-SNAPSHOT")
(def v-refactor-nrepl "2.4.0-SNAPSHOT")

(deftask cider "CIDER profile"
  []
  (require 'boot.repl)
  (swap! @(resolve 'boot.repl/*default-dependencies*)
         concat `[[org.clojure/tools.nrepl ~v-tools-nrepl]
                  [cider/cider-nrepl ~v-cider-nrepl]
                  [~'refactor-nrepl ~v-refactor-nrepl]
                  ])
  (swap! @(resolve 'boot.repl/*default-middleware*)
         concat '[cider.nrepl/cider-middleware
                  refactor-nrepl.middleware/wrap-refactor
                  ])
  identity)

Without (dirac) in place in the boot dev task, substituting the boot dev mentioned above with boot cider dev and running cider-connect followed by (start-repl) seems to be working nicely and allows me to eval cljs from the emacs instance.

Edit:
With these versions of boot and clojure, on java 9
