Ultisnips: Restore Session Triggers Error

Created on 24 Dec 2015 · 28Comments · Source: SirVer/ultisnips

I'm encountering a series of UltiSnips errors after sourcing a vim session file. These errors do not appear if I edit a file before restoring my session. However, if I restore a session from a blank gvim instance (I'm on Windows 8.1) I encounter the following errors:

"hello.go" 7L, 128C

I use Vundle to manage my plugins and my vimrc file(s) can be found on my github page: https://github.com/fuzzybear3965/vimrc. My Python version is 2.7.9.

can't reproduce good first issue pending feedback possible bug

@fuzzybear3965: Please, provide sequence of vim commands that evaluates to error.

seletskiy on 25 Dec 2015

F3. This is the only key that I have to press immediately after opening a Vim instance. I have the following defined in my vimrc file:

nmap <F3> :wa<CR>:source $HOME/vim_session<CR> " Load session from file

johnrichardrinehart on 25 Dec 2015

@fuzzybear3965: Can you reduce test scenario to minimal reproduceable on your workstation vimrc and sequence of actions (e.g. opening file a.go, :mksession ..., ...)?

seletskiy on 25 Dec 2015

@fuzzybear3965: Because I cannot reproduce it.

seletskiy on 25 Dec 2015

@fuzzybear3965: ping.

@seletskiy I'm very sorry to leave this for so long. Since we last spoke I have changed Vim versions (I compile the latest version with patches daily) and I have (possibly) changed which plugins I use with Vim (I used Vundle to manage my Vim plugins).

I can no longer reproduce this error, myself. I remember that this behavior was occurring whenever I loaded a Vim session which had an active buffer of the latex filetype. Today, I have created a reasonably active vim session (editing latex files, java files, go files - any filetype that I may have been working on at the time that would have stimulated the string of errors given in the first post). Everything works great. So, I guess this issue can be marked as closed. I'm also sorry that I didn't track the changes to my Vim set-up. I hope no one else in the future has this problem.

Note: If you have this issue in the future, please check my vimrc files. I pushed today's version of my vimrc files to Github. These files represent a working configuration. My most recent Vim version is as follows:

Currently I reproduce the same error in vagrant-ubuntu-trusty-64 environment when I try to open new file from vim started without arguments. Some useful parts of my Vagrantfile:

Vagrant.configure(2) do |config|
  config.ssh.forward_agent = true
  config.vm.box = "ubuntu/trusty64"
  # issue can be reproduced on default Virtualbox synced folders backend
  # nfs just works faster
  config.vm.synced_folder "..", "/home/vagrant/workspace", type: "nfs"
end
# vim:et sw=2 ft=ruby

My dotfiles are https://github.com/DXist/dotfiles. They require ansible and make for provisioning. You may run make to do full environment setup (takes some time) and make update_vim to install NeoBundle plugins.

DXist on 27 Jan 2016

@DXist, @fuzzybear3965: Can you post session file, which triggers error?

seletskiy on 2 Feb 2016

@seletskiy , just open new file with :e /tmp/test.py inside vim with welcome screen to reproduce the error in my environment.

DXist on 2 Feb 2016

@DXist: Is it reproduceable with _only_ UltiSnips plugin enabled?

seletskiy on 2 Feb 2016

@seletskiy , yes it is. I commented out all NeoBundle calls except UltiSnips and got the same error when open empty /tmp/test.py. Also I tried to open /tmp/test file to disable impact of my config for python filetype. I got similar traceback when I hit c-j and activate UltiSnips#ExpandSnippetOrJump function.

DXist on 2 Feb 2016

@DXist, @fuzzybear3965: Sorry, currently I have no time to track down that problem. Personally I do not use sessions. However, I will gladly merge PR if you will find the problem and fix it.

seletskiy on 1 Apr 2016

@seletskiy, I don't use this old Debian environment any more so I don't have interest in this issue too.

DXist on 1 Apr 2016

@DXist: OK, thanks for the reply.

seletskiy on 1 Apr 2016

Hey, sorry to be out of this loop for so long, you guys. Actually, this issue comes up, still, and I'm not sure how I ever avoided it being a problem, before, when I claimed that I could not reproduce it. I will take a look into this to see if I can fix this. My VimScript powers are pretty limited, though. I will document my progress on addressing this bug, below.

Minimum working text file is blank.
F2 to save a session in accordance with the following .vimrc nmap

nmap <F2> :wa<CR>:mksession! $HOME/vim_session<CR> " Write session to file

:wqa to save the 0-byte file to disk.
F3 to restore a session in accordance with the following `.vimrc nmap

nmap <F3> :wa<CR>:source $HOME/vim_session<CR> " Load session from file

johnrichardrinehart on 1 Apr 2016

Note that the session file seems to be generated with many nonprintable characters. I thought this may be the source of the error, so I decided to remove the plugins emmet-vim and vim-javacomplete2 that seemed to have a bunch of these unprintable characters associated with them in the session file. I then repeated the above steps.

The following is the generated session file. No errors were generated on restoring my session! I have since tried the above steps with more difficult sessions (different file types in different windows) and I haven't had a problem. I will try enabling these plugins 1-by-1 to see if either the java plugin or the emmet plugin is solely responsible. Note that the generated vim_session file still has nonprintable characters. So, that may/may not be the source of the problem.

They seem to, each, generate UltiSnips errors when they are individually included. So, it was pure luck that I decided to remove both and it fixed my problem. I needed to remove both and not just one plugin. At this point, I'm going to investigate why :mksession is adding weird, nonprintable characters to my session file. I think that's the best line of attack. The fault may lie in the courts of UltiSnips and/or vim. I'll be in touch.

johnrichardrinehart on 1 Apr 2016

Non-printable chars are OK in the session file, I guess. They are raw
representation of escape sequences and control-key sequences.

But, why are there weird newlines, bel, shift in, cancel characters, etc.? I've identified a number of the control-key sequences from this table. It doesn't seem that these should be there. You can see a screenshot of some of the session file here.

I confirm the same problem on OS X / Vim 7.4.1755. Here is the warning that I get when I try to restore a saved session:

I have been having the same issue. I just learned about how to use mksession, but once I restore I get similar explosion

umamiMike on 8 Jun 2018

The error messages you guys are seeing are actually due to a bug in the Vim source code for session script generation. This is a known issue. Refer to: vim/vim#3466.

Basically, when the 'runtimepath' setting gets too long (i.e., when you have a lot of plugins), it gets cut off when written to your session script. You then load the session script, and Vim can't find some of the Python modules it needs to load. @johnrichardrinehart, this is why you didn't get any errors when you removed those plugins. You just made your 'runtimepath' shorter.

Hopefully, this problem will be fixed soon, there is a patch, but it seems that more work is needed... not sure on a timeline.

For now, you can get around the problem with something like:

let g:my_rtp = &rtp
source Session.vim
let &rtp = g:my_rtp

This may not always work. Really, the bug just needs to be fixed in Vim so that sessions work as expected.

Looks like Bram just merged the patch that fixes this. So, this should no longer be a problem for users who keep Vim up-to-date.

lifecrisis on 24 Jan 2019

UPDATE: The patch that was merged seems to not actually fix the problem on Microsoft Windows. Hopefully, this will be addressed. In any case, the cause of this issue is pretty clear.

lifecrisis on 27 Jan 2019

I just installed ultisnips today and I'm experiencing a similar issue that's definitely related to :mksession. If I type a single key before sourcing a saved session, the issue does not exist. However, in that case ultisnips also doesn't work. If I then source my _vimrc again, ultisnips works and I don't receive any errors.

If I source my session immediately, without typing a single key in insert mode, I receive the following error on every single key I type, quickly filling the screen:
