Issue Details

Hi,

I've just upgraded from Ubuntu 14.04 to 16.04 and this has broken my ycm plugin. I'm a user of ycm, not very familiar with its internal structure, I'm having some trouble following the fixes posted on the forum for this issue and I was wondering if you could help me out?

My vim version info is as follows:

Looking around, I found issues [2002] and [2136]. I realise that this is a python2/python3 problem, with (I think) python2 being the default insterpretter under ubuntu 16.04, but default vim compiled with python3 support. I've tried recompiling vim with python2 support (as you can from the above), but I am still getting error messages when I start vim:

Since my version of ycm was a couple of years old, I tried updating it using vundle using :PluginInstall!, although vundle is also giving me some error messages:

Error detected while processing function vundle#installer#new..<SNR>23_process..vundle#installer#run..vundle#installer#install..<SNR>23_sync.. <SNR>23_make_sync_command..<SNR>23_get_current_origin_url..<SNR>23_system: line 1: E484: Cannot open file /tmp/vdLMLOr/1 Error detected while processing function vundle#installer#new..<SNR>23_process..vundle#installer#run..vundle#installer#install..<SNR>23_sync: line 6: E714: List required Error detected while processing function vundle#installer#new..<SNR>23_process: line 13: E121: Undefined variable: g:vundle_last_status E15: Invalid expression: 'error' == g:vundle_last_status line 17: E121: Undefined variable: g:vundle_last_status E15: Invalid expression: 'updated' == g:vundle_last_status && empty(msg)

A lot of the information on forum start with going to ~/.vim/bundle/YouCompleteMe and running install.py, but my direction doesn't contain an install.py, just an install.sh.

I'm sure I am being quite stupid here, but can anyone point me in the right direction?

Many thanks,
Matt

[If filing a bug report, please include a list of steps that describe how to
reproduce the bug you are experiencing. Also include test code if relevant.]

[Valloric]

Are you using the latest version of YCM?

[soolijoo]

To be honest, I'm not sure. Updated the version I have using vundle but I haven't downloaded anything new from the ycm website. I have the strong impression I am doing some thing wrong...

[micbou]

@soolijoo Since you can't update YCM through Vundle, go to the ~/.vim/bundle/YouCompleteMe folder and run the following commands:

git pull
git submodule update --init --recursive

The install.py script should now exist. Use it to install YCM. See the instructions in the documentation for more details.

Concerning your Vundle issue, you should search about the error on the Vundle issue tracker. I think this is related to VundleVim/Vundle.vim#175 and this FAQ entry.

[soolijoo]

thanks for this. I've pulled the changes from the git repo, but the submodule update is giving me:
error:

Your local changes to the following files would be overwritten by checkout:
cpp/ycm/.ycm_extra_conf.py
Please, commit your changes or stash them before you can switch branches.
Aborting
Unable to checkout 'b3643cecd7cf152b79d82ca42741969b4d06fc71' in submodule path 'third_party/ycmd'

I have previously made some changes to my ycm_extra_conf.py in line with the installation instructions. I can easily put them back in a fresh script later.

[micbou]

You should not use YCM own .ycm_extra_conf.py. Copy it to a separate folder (your home for instance), rename it to something else (e.g. .ycm_global_extra_conf.py), and update the g:ycm_global_ycm_extra_conf option in your vimrc to its new path:

let g:ycm_global_ycm_extra_conf = '~/.ycm_global_extra_conf.py'

You can now discard the changes you made to YCM .ycm_extra_conf.py file by moving to the ~/.vim/bundle/YouCompleteMe/third_party/ycmd folder and running the following command:

git checkout -- cpp/ycm/.ycm_extra_conf.py

Then try again to update the submodules (git submodule update --init --recursive) in the YCM folder.

Ok, that worked, and I have run setup.py --clang-completer successfully. I'm still getting errors when I use vim to open a c language file, though. About 20 of them, all on line 2. here's a sample:

I noticed during the setup that the script found python2.7 -- could this be what's causing the problem?

[micbou]

Could you paste the full output of the error? Use the :messages command for that.

I noticed during the setup that the script found python2.7 -- could this be what's causing the problem?

No, this is expected on Ubuntu 16.04.

[micbou]

Thanks. Could you check if this line (/semantic_completion_available handler) exists in your YouCompleteMe/third_party/ycmd/handlers.py file?

[soolijoo]

Checking line 164 of file ~/.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/handlers.py. This block is:

@app.post( '/semantic_completion_available' ) def FiletypeCompletionAvailable(): _logger.info( 'Received filetype completion available request' ) return _JsonResponse( _server_state.FiletypeCompletionAvailable( RequestWrap( request.json )[ 'filetypes' ] ) )

[micbou]

Does the error also occur for languages other than C (for instance in Python files)? Do you get the error when running the :YcmDebugInfo command in Vim? If not, could you paste its output?

[soolijoo]

I'm getting a similar set of errors when I start vim with a python file. The output of YcmDebugInfo is:

So, the server is crashing. Add the following to your vimrc:

let g:ycm_server_keep_logfiles = 1
let g:ycm_server_log_level = 'debug'

Start Vim, reproduce the issue, and type the command :YcmToggleLogs stderr. This should open the server logfile in a new window. Paste its content. If you get an error saying that the logfile cannot be opened or there is nothing in it, paste instead the output of this command:

:py print(ycm_state._server_popen.stderr.read())

[micbou]

No answer. Closing.
