First require locks up neovim for ~10 seconds #82

devth · 2019-01-08T00:58:07Z

After :IcedConnect the first :IcedRequire locks up neovim for about 10 seconds. During this time I can't move the cursor or do anything inside neovim. After that subsequent :IcedRequires run nearly instantly.

NVIM v0.3.2-996-g55c518588
Terminal: kitty 0.13.1

Ref #77

@devth Thank you for the reporting!

Does this problem occur in any project?
Could you provide the steps to reproduce?

devth · 2019-01-08T18:45:47Z

I tried it in my yetibot project. It seems to repro on any file I try requiring after initial :IcedRequire.

Trying on a fresh project doesn't seem to freeze:

lein new iced-repro
cd iced-repro
iced repl

In neovim:

nvim src/iced_repro/core.clj
:IcedConnect
# nvim freezes for about 1 second 
<Leader>eb
# no freeze

So it doesn't appear to happen on a fresh project. I'll keep playing with it. Maybe has to do with how much source code is in the project?

Noticed a large error after connecting and trying to :IcedEval a simple expression:

After that when I try to :IcedEval anything it just says Still reading....

liquidz · 2019-01-09T01:30:40Z

@devth I couldn't reproduce the problem with following steps...

git clone https://github.com/yetibot/yetibot
cd yetibot
iced repl
nvim src/yetibot/api/catchpoint.clj
- run :IcedConnect
- run :IcedRequire
- run :IcedEval (+ 1 2 3)

I uses nvim 0.3.2.
https://github.com/neovim/neovim/releases/tag/v0.3.2

$ nvim --version
NVIM v0.3.2
Build type: RelWithDebInfo
LuaJIT 2.0.5
...

It seems to me you use nvim 0.3.2(nightly), so could you update nvim 0.3.2(released) or later and test again?

devth · 2019-01-09T17:58:31Z

Upgraded to NVIM v0.4.0-1183-g8510d5ff8.
Also upgraded to latest commit on vim-iced dev branch.

Opened new neovim instance
Ran iced repl in a terminal inside vim
Opened slack.clj
:IcedConnect
<Leader>eb - immediately says Required in the statusline but then locks up for 10 seconds

liquidz · 2019-01-10T23:55:08Z

@devth Thanks!
But I cannot reproduce yet..
I'll keep testing with yetibot.core

devth · 2019-01-11T15:36:15Z

Strange. I will also keep testing on my side and see if I can narrow down what's going on!

liquidz · 2019-01-15T04:56:15Z

@devth

eb - immediately says Required in the statusline but then locks up for 10 seconds

The fact that "Required" is output means IcedRequire should have finished.
So something else should be running afterwards. (It may be other configurations or other plugins)

I made a minimal configuration for vim-iced for breaking down this problem.
https://scrapbox.io/vim-iced/Minimal_configuration
Could you launch nvim with this minimal configuration and test again?

devth · 2019-01-17T23:30:28Z

Sorry for the delay. I was able to repro the same issue in the paired down nvim with minimal config.

liquidz · 2019-01-21T04:07:00Z

@devth
I can reproduce the problem finally!!
Do you have :plugins [[cider/cider-nrepl "..."]] in your ~/.lein/profiles.clj?

cider-nrepl plugin injects all cider-nrepl middlewares containing track-state.
https://github.com/clojure-emacs/cider-nrepl/blob/v0.20.0/src/cider/nrepl.clj#L511
track-state middleware will send a huge data after requiring namespace, and it take times.

iced command is excluding track-state middleware intentionally.
https://github.com/liquidz/vim-iced/blob/0.9.2/clj/iced_repl.clj#L4-L18
So if you have :plugins [[cider/cider-nrepl "..."]] in your ~/.lein/profiles.clj, please delete it.

devth · 2019-01-21T16:41:26Z

Amazing! Nice job. I will try this out soon. I always thought cider-nrepl was required.. at least it is for the other vim clojure plugins I've tried: acid.nvim and vim-fireplace. 🤔

liquidz · 2019-01-21T23:46:21Z

@devth Other plugins may require cider-nrepl while iced command injects dependencies automatically.
https://github.com/liquidz/vim-iced/blob/0.9.2/deps.edn#L5

I'll fix to work with track-state middleware in the future.

knubie · 2019-03-19T17:22:51Z

I'm having a similar issue with my shadow-cljs project.

It seems that shadow-cljs includes the cider-nrepl plugin (which includes all the middleware) when cider/cider-nrepl is detected in your dependencies.

At the moment there's no way to turn this feature off.

liquidz · 2019-03-20T04:33:28Z

FYI
https://github.com/thheller/shadow-cljs/blob/2.8.19/src/main/shadow/cljs/devtools/server/nrepl.clj#L303-L311

knubie · 2019-03-23T00:12:20Z

@liquidz After speaking to the maintainer of shadow-cljs on slack, you can now disable the automatic inclusion of cider middleware as of 2.8.20!

I just tried it out and the delay is gone now.

liquidz · 2019-03-23T00:54:49Z

@knubie Wow! That's awesome!!
