Cannot read anaconda-mode server response #295

seagle0128 · 2018-06-02T15:14:16Z

GNU Emacs 16.1
macOS 10.13.4
Python 3.6.5
pip 10.0.1
setuptools 39.2.0
anaconda-mode-0.1.12

I installed anaconda-mode 20180602.321 with the config below.

(use-package anaconda-mode
    :ensure t
    :defer t
    :diminish anaconda-mode
    :init
    (add-hook 'python-mode-hook #'anaconda-mode)
    (add-hook 'python-mode-hook #'anaconda-eldoc-mode)
    :config
    (with-eval-after-load 'company
      (use-package company-anaconda
        :defines company-backends
        :init (cl-pushnew (company-backend-with-yas 'company-anaconda) company-backends))))

The anaconda-mode was installed correctly, but I got the error while editing the python file.

Cannot read anaconda-mode server response

I checked *anaconda-response* buffer

# status: nil
# point: 1

and *anaconda-mode* buffer

anaconda_mode port 55585

The text was updated successfully, but these errors were encountered:

Hi, looks like an empty response from the server. Maybe socket was closed.
By the way, try 0.1.12 version.

seagle0128 · 2018-06-02T16:29:57Z

Actually I am using 0.1.12. It worked well before.

seagle0128 · 2018-06-05T15:49:48Z

Today, I delete ~/.emacs.d/anaconda_mode/ and restart Emacs. The screenshot is below. Seems not all python packages were installed.

proofit404 · 2018-06-05T17:35:07Z

anaconda_mode server is not necessary anymore and will be removed from the pypi soon.

seagle0128 · 2018-06-06T01:57:36Z

Okay, but it doesn't work for me yet. No response from server :(
What should I do for further troubleshooting?

proofit404 · 2018-06-06T05:54:05Z

Does this happens to all requests?

seagle0128 · 2018-06-06T05:56:58Z

Yes, for all requests on my macOS 10.13, Emacs 26.1 (Python 3.6).
I tested on Ubuntu 18.04 with Emacs 25.2 (Python 2.7/3.6) today. It works well after I deleted ~/.emacs.d/anaconda_mode/ and reinstalled it.

I missing anything here?

proofit404 · 2018-06-06T06:01:59Z

Mac OS is problematic for some reason. I never heard a chance to debug it since I limited to my Linux laptop.

I will provide you with detailed guide if you have a patience to debug it.

seagle0128 · 2018-06-06T06:03:56Z

Sure, please let me know. I will try to do that.

proofit404 · 2018-06-07T05:27:31Z

Here we go.

This is our first try at debugging this nasty issue.

Update anaconda-mode from master or wait for next melpa build.
Disable eldoc mode.
Add code belove at the end of your config.
Restart emacs and call exactly one interactive command (M-. for example).

Following by the steps you provided, I got these messages.

anaconda.log

proofit404 · 2018-06-08T21:25:37Z

From this log, I can tell that Emacs request never reaches anaconda mode server.

Can you read an overview of the Edebug manual? We need to trace anaconda-mode-call (C-u C-M-x) and then set a break point inside the response handler.

seagle0128 · 2018-06-10T12:21:31Z

I tried to debug today, but not sure whether the steps are correct.
If enabling anaconda-eldoc-mode, anaconda-mode-call can be traced, and the outputs are below:

Result: "eldoc"
Result: anaconda-mode-eldoc-callback
Result: #<buffer  *http 127.0.0.1:62932*>
Result: #<killed buffer>

Otherwise, no traces happened.

proofit404 · 2018-06-12T13:31:45Z

Hi, I think we should try following.

Disable eldoc mode.
C-u C-M-x under anaconda-mode-call.
Press M-. under some python definition.
When debugger showed up in the anaconda-mode-call set breakpoint inside lambda function returned by response handler.
Continue execution, the debugger showed inside the lambda.
Trace this function.

If response buffer contains empty response, I afraid bug sits somewhere in emacs HTTP library. In this case, we should use network debugging tool like Wire Shark.

Please remove all elc files form .emacs.d/elpa/anaconda-mode-... directory and repeat. Turns out we can't step over byte-compiled functions.

proofit404 · 2018-06-14T04:12:12Z

Hi, I can see that you evaluate response handler to lambda but didn't set a breakpoint inside it.

Please look at this docs https://www.gnu.org/software/emacs/manual/html_node/elisp/Breakpoints.html

Than use b somewhere inside lambda function https://github.com/proofit404/anaconda-mode/blob/9d9b1781fc63998245485ae0a4c03b54bcbe12ed/anaconda-mode.el#L443

Things get too messy to follow. Can you redo last debugging with the gif-screencast package so I can follow the process? Please, attach resulted gif to the issue.

Also, try to change 127.0.0.1 to localhost in the anaconda-mode-host function, eval it, and retry.

OK. Updated as below.
auto-complete works now, but M-x M-. doesn't work yet.

debug.log

*Anaconda* buffer.

list(iterable) -> new list initialized from iterable's items

proofit404 · 2018-06-18T10:37:19Z

Can you remove lines from this condition starting from the last one to the first one, and say from what point it starts working? https://github.com/proofit404/anaconda-mode/blob/04709854cc4ca98d4b5dbcbf4176f4ef02de2ae8/anaconda-mode.el#L441-L445

As for no definitions message, this is actually to say that emacs lisp interaction with python works but python indeed returns an empty result.

seagle0128 · 2018-06-18T14:50:29Z

I didn't find these lines in the original codes you provided. I changed the codes as above and debug again. Not sure if it's what you want.

debug.log

list is defined in sys compiled module

Hi, I've fixed server port bind bug in master.

Please, check if empty responses still come from the HTTP library.

seagle0128 · 2018-06-20T14:43:27Z

I upgraded anaconda-mode to 20180620.123. Still doesn't work as before, including auto complete and go-to-definition.

I changed "127.0.0.1" to "localhost" in anaconda-mode-host, then auto complete does work. This issue exists on macOS, while not Linux and Windows. why??? :-(
M-x M-. returns list is defined in sys compiled module, both on Windows and macOS.

proofit404 · 2018-06-20T22:48:20Z

Messages like listdir is defined in posix compiled module is expected behavior for things written in C or Cython.

I changed host recognition logic. Please retry with the latest master and try to go to definitions for packages installed with pip. Like Django, Flask or whatever.

proofit404 · 2018-06-20T22:49:37Z

why??? :-(

I'm asking this myself for 3 years already...

seagle0128 · 2018-06-21T13:45:54Z

It was fixed. Works on macOS, Windows and Linux. Thanks very much!

cank · 2018-06-27T18:22:29Z

This fix seems to now break anaconda for me in OS X. Changing 'localhost' back to '127.0.0.1' in the darwin block fixes it.

proofit404 · 2018-06-27T20:59:06Z

What is the actual fuck is going on?!

I'm so tired of this issue...

seanfarley · 2018-06-27T22:55:38Z

Can confirm about the localhost / 127.0.0.1 issue. I wonder if this is an ipv6 issue?

tonyslowdown · 2018-07-03T08:30:22Z

Also confirming that changing anaconda-mode-host to return 127.0.0.1 for darwin fixes the issue

preppypiet · 2018-07-06T12:38:28Z

This is also broken for me on macOS.

seagle0128 · 2018-07-06T12:52:16Z

So wired...

preppypiet · 2018-07-06T12:52:47Z

Yeah, changing to "127.0.0.1" from localhost for darwin fixed it for me too.

labrook · 2018-07-07T01:25:36Z

~~Nope, still have the same error message after changing localhost to "127.0.0.1"~~

Scratch that. My issue was due to the version of jedi and it was a different error message like here.

After upgrading jedi to 0.12 and also change "localhost" to "127.0.0.1", it's fixed.

proofit404 · 2018-07-07T17:14:30Z

Fixed second time in https://github.com/proofit404/anaconda-mode#faq

@seagle0128 please use the tweak.

seagle0128 · 2018-07-08T06:19:19Z

@proofit404 Thanks! It's really wired, but the tweak works fine for me.

kanodiaayush · 2022-05-31T08:01:08Z

I am unable to make this run using both 127.0.0.1 and localhost. I'm on doom-emacs. Any suggestions? I tried also bypassing proxy for 127.0.0.1 and `localhost'

please open a new issue and share the output of *anaconda-response* buffer.
