Company-robe got stuck contacting host

islam-taha commented 7 years ago

After about 1 minute using company robe with a single file, when trying to type any characters, it seems to be stuck contacting robe host.

Here is a snippet of my company-backends configuration.

(setq company-backends
      '((company-files
         company-keywords
         company-css
         company-yasnippet)))
(setq company-quickhelp-mode 1)
(setq company-idle-delay 0)
(setq company-minimum-prefix-length 1)
(setq company-auto-complete 'company-explicit-action-p)
(setq company-auto-select-first-candidate nil)
(setq company-selection-wrap-around t)

Any help would be appreciated!

Does C-g break you out of the freeze? Is there anything interesting in the REPL buffer (you can switch to it with C-c C-z)?

dgutov commented 7 years ago

Using M-x toggle-debug-on-quit, you can obtain the backtrace the next time it freezes and you press C-g.

dgutov commented 7 years ago

And finally, please post the output of M-x company-diag.

islam-taha commented 7 years ago

Yes, C-g break me out of the freeze, and here is the output of company-diag.

Debugger entered--Lisp error: (quit)

dgutov commented 7 years ago

Thanks. Now, please answer the remaining two questions.

islam-taha commented 7 years ago

Nothing interesting in the REPL buffer, here is what appear in the messages buffer:

Contacting host: 127.0.0.1:53127
eldoc error: (error Transfer interrupted!)
Company: An error occurred in auto-begin
Company: backend company-robe error "Transfer interrupted!" with args (candidates ss)

and nothing appear as a backtrace when quitting while enabling toggle-debug-on-quit.

dgutov commented 7 years ago

I see. Could you paste the contents of your Gemfile.lock here?

Or, better, yet, post an example project where I can reproduce this error.

dgutov commented 7 years ago

And also:

please post the output of M-x company-diag

islam-taha commented 7 years ago

For company-diag the same happens while typing, seems to be stuck in contacting host, here is the contents of Gemfile.lock:

RUBY VERSION
   ruby 2.3.1p112

BUNDLED WITH
   1.15.0.pre.4

I'll try to get a sample project also, thanks for reply.

dgutov commented 7 years ago

Thanks. I see no known offenders, unfortunately.

dgutov commented 7 years ago

Also, what are your Emacs and Ruby versions?

islam-taha commented 7 years ago

Emacs version: GNU Emacs 26.0.50 Ruby version: ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin16]

islam-taha commented 7 years ago

Also something weird happening makes robe consume way much cpu!, here is a screenshot.

dgutov commented 7 years ago

These two things are most likely directly related. It's taking too long to complete a request, and using as much CPU as it can while doing it.

dgutov commented 7 years ago

I've played around with a new Rails 5.1.1 application, and couldn't reproduce.

dgutov commented 7 years ago

BTW, try updating your Emacs snapshot. When was it built?

islam-taha commented 7 years ago

It may seem weird, but it's working now as excepted, hopefully this issue won't happen again.

Thanks for your help!

vlymar commented 7 years ago

I've been dealing with the same issue since I switched to emacs (spacemacs) several weeks ago.

I have identical symptoms to @islam-taha:

toggle-debug-on-quit traceback:

  url-retrieve-synchronously("http://127.0.0.1:49448//complete_method/a/-/-/yes" t)

  robe-request("complete_method" #("a" 0 1 (fontified t)) nil nil t)

Nothing interesting in repl buffer, just "robe on 49448".

CPU consistently sits at 99%, until I kill the process.

I've also noticed these processes appear (with M-x list-processes). emacs truncates the address, but when i inspect it, the port shown in the url is associated with the ruby process.

I love robe and would really like to try to get to the bottom of this, so let me know how I can help.

dgutov commented 7 years ago

Emacs 25.2.1

That's a bad news.

(x86_64-apple-darwin16.5.0)

Any chance you can try the same Emacs configuration and the same project on GNU/Linux, for comparison?

so let me know how I can help

I don't see a way to debug this without reproducing. So please try creating a small project where this happens (or point to an existing one, if it's publicly available, or send it to me by email), and outline the steps to reproduce it.

Alternatively, you could give me access to your machine where such project lives. This would require a certain degree of trust anyway, though.

vlymar commented 7 years ago

Unfortunately I can't give you access to my machine or this project. I will work on finding a reproducible case. I don't have a linux machine to test on, but I can try to set to set up a vm.

dgutov commented 5 years ago

I have finally stumbled on an error that looks related and might be hitting the same underlying problem. Filed a bug report. Let's see how it goes: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=34763

dgutov commented 5 years ago

Is anybody having this problem still with us?

Is it still present when using the latest master?

dgutov commented 4 years ago

Looks like I finally managed to trigger this semi-reliably with a new, faster Ruby.

The misbehavior seems to be on Emacs' side, but the server here clearly hasn't been doing enough to protect itself against that sort of thing. Fix incoming, fingers crossed.
