xmlrpc ResponseError #22

alazyworkaholic · 2020-11-14T07:15:10Z

After leaving Dokuvimki aside for several months I fired it up again and found it won't start. Unfortunately, I don't remember at all what I might have done to the computer during that busy time that caused this issue. Dokuwiki itself continutes to run perfectly well through the browser.

Ubuntu 20.04 x64

Upon starting nvim and running DokuVimKi.

So I try a health check:

I see the python 2 error that msgpack and pynvim are missing but I think it's irrelevant because DokuVimKi should (I think) use python3, which doesn't show any checkhealth error.

How can I find out what's gone wrong with the xmlrpc response handling?

I've tried installing dokuvimki on another machine that's just had a fresh OS install but get a different yet similar error:

Steps:

Insert into ~/.local/share/nvim/site/pack/alazyDokuVimKi.vim

let g:DokuVimKi_USER = 'myUser'
let g:DokuVimKi_PASS = 'myP@$$'
let g:DokuVimKi_URL = 'http://192.168.2.46/dokuwiki/doku.php'
let g:DokuVimKi_INDEX_WINWIDTH = 20

Insert into ~/.config/nvim/init.vim

let alazyDokuVimKi = $HOME . "/.local/share/nvim/site/pack/dokuvimki/alazyDokuVimKi.vim"
if filereadable(alazyDokuVimKi)
    execute 'source  '.alazyDokuVimKi
endif

I'm relying on neovim/vim8 native plugin management and am using python3, but I think that should still work. Would you be able to pass on any XML-RPC Error Codes so one can have some idea of what's wrong?

xmlrpc isn't totally dead. I'm taking some agonizingly slow baby steps to figure this out but python3 dokuwikixmlrpc.py -w http://192.168.2.46/dokuwiki -u myUser -p my P@$$ --allpages returned my list of pages!

Yes, if Vim is built with Python 3 support, that is used. Otherwise Python 2.

I've just tried NeoVim and it seems to be working for me:

$ sudo apt install -y neovim python3-pynvim
$ mkdir -p ~/.config/nvim
$ echo "source ~/.config/vim/vimrc" > ~/.config/nvim/init.vim
$ nvim +DokuVimKi

I think the URL in your Vim config may be wrong. I should be the root of your wiki, since dokuwikixmlrpc will append /lib/exe/xmlrpc.php to it.

Can you try setting it to the same URL you used when you tried via dokuwikixmlrpc.py directly?

let g:DokuVimKi_URL = 'http://192.168.2.46/dokuwiki'

kynan · 2021-04-03T10:35:18Z

I just tried appending /doku.php to my own wiki URL and I'm seeing the following failure:

Failed to parse response. Is the DokuWiki XML-RPC server enabled?

If I disable error handling in dokuwikixmlrpc (by commenting these lines) I get the following backtrace:

@alazyworkaholic is this still an issue for you?

kynan · 2022-01-30T16:53:56Z

@alazyworkaholic any update?
