emacs-jedi on windows? deferred error

[vinhdizzo]

Hi,

I'm trying to get emacs-jedi working on my windows laptop (have it working on mac os x and ubuntu). I'm using the same ~/.emacs.d directory (so all the emacs packages are the same across machines), and I have the python dependencies installed (epc and jedi). However, when I'm at a python buffer, I get these messages in the minibuffer:

deferred error : (error Timeout server response.)
deferred error : (error Creating pipe: too many open files)

Hence, autocomplete does not work. Any thoughts on how to fix this or which avenue I should be looking at? Thanks.

If I list the processes in emacs, I see the following:

epc:server:10 run epc:server... -- python2.7 ~/.emacs.d/emacs-jedi/jediepcserver.py
epc:server:11 run *epc:server... -- python2.7 ~/.emacs.d/emacs-jedi/jediepcserver.py

You are sharing elc files also? It causes problem when you are using different Emacs versions because elc format is not compatible across different Emacs versions.

The best way to investigate this is to use make tryout but probably installing Make is hard in Windows...
http://tkf.github.io/emacs-jedi/latest/#troubleshooting

Do you see some traceback in relevant _*epc:server:N* (_ is a space and N is a number) buffer? You may be able to open that buffer by M-x epc:pop-to-last-server-process-buffer RET when you get the error.

[vinhdizzo]

I'm not using elc files. I don't byte compile my code, so I just use the .el files directly. Issues should not be from that.

When I pop to last server process buffer, it goes to the buffer epc:server:2, where the buffer only contains the value "1323" without the quotes.

From the troubleshooting page, I ran the function jedi:show-jedi-version and got the message "Timeout server response.".

Does this mean it's a jedi issue in python? When I launch python, I'm able to import jedi. When I do help(jedi), I see this as the file reference: /usr/lib/python2.7/site-packages/jedi-0.6.0-py2.7.egg/jedi/init.py.

I can also import epc and argparse.

Thoughts?

My guess is that launching external process in Windows takes long time and that's why you get timeout. Try this:

(setq epc:accept-process-timeout 1000)

This increases timeout to 30 second from 3 second (default).
Default epc:accept-process-timeout is 100.

You may be able to decrease epc:accept-process-timeout a little bit.

Will try this in a bit. Just remembered one thing. What port is used for
epc by default? I might have to allow that port on windows. Had to do the
same for sshd. Let me know, thanks.

You are right this fixes the issue for me! Thanks so much!!!

If you find a good epc:accept-process-timeout value for your Windows machine, please report it in kiwanami/emacs-epc#15 (just for a data point).
