I have installed the snippets plugin and the bootstrap3 / bootstrap-wrapper plugin

https://www.dokuwiki.org/plugin:snippets https://www.dokuwiki.org/template:bootstrap3 https://www.dokuwiki.org/plugin:bootswrapper?s[]=bootstrap&s[]=wrapper

Expected Behavior

The editor buttons opens a pupup.

Current Behavior

Pupup ist blank, debugging shows a http 500 error The follwing ULR is openend in the popup window

http:///lib/plugins/snippets/exe/snippets.php?ns=&edid=wikitext or http:///lib/plugins/bootswrapper/exe/popup.php?ns=&edid=wikitext

Debugging the URL from the popup window shows the http-error

I tried a Docker exec into container and look the nginx-error.log

The nginx shows some more error

I tried a link

drwxr-xr-x 4 abc  users 4096 Dec 19 20:17 lib

but this gave me a Cache not accessible error

I guess the inc(lude) directory is at the wrong place in the docker container, plugins with this code

if(!defined('DOKU_INC')) define('DOKU_INC',dirname(__FILE__).'/../../../../');
define('DOKU_MEDIAMANAGER',1); // needed to get proper CSS/JS
require_once(DOKU_INC.'inc/init.php');

starting from the code like

/config/dokuwiki/lib/plugins/<pluginName>/exe/plugincode.php

for example

/config/dokuwiki/lib/plugins/snippets/exe/snippets.php

would fail, because the builded path points to 

/config/dokuwiki/lib/plugins/snippets/exe/../../../../inc/init.php

Similar problem with searchindex plugin. The plugin gave me a 500. Looking into nginx logs, I found that the error was because dokuwiki could not find init.php. But the plugin has the correct path: https://github.com/splitbrain/dokuwiki-plugin-searchindex/blob/32e56a59996ea3a10b3a70f0239fc13d58f1174b/ajax.php#L17 (I checked it works perfectly from a local php installation).

avks commented 4 years ago

I guess the inc(lude) directory is at the wrong place in the docker container, plugins with this code

This is definitely the case.

avks commented 4 years ago

I noticed that /config (which can be mounted on host system) doesn't contain inc dir, although it contains other dokuwiki dirs.

I went a little backwards and found that lsiobase-alpine on which this image is based doesn't contain anything about /config.

But lsiobase-nginx does expose /config as a volume. Now, this dokuwiki image extracts the dokuwiki tar file into /app. So inc should be inside /app/dokuwiki (which is true since I can verify it from inside the container). I am really missing something here as I can't identify how /app and /config are connected.

avks commented 4 years ago

Okay, I found it here.

So basically, the image is built by copying only certain directories to /config, and /inc remains inside /app. And then, creates symlinks. Could this problem be due to symlinking? Could just create symlinks (and not copy individual dirs)?

avks commented 4 years ago

Okay, spent sometime debugging the issue. Inside the container, I ran:

cd /config/dokuwiki && ln -sf /app/dokuwiki/inc inc

The plugin started working. Now, from inside my host volume, I see that only the symlink is mounted; no access to dokuwiki core files.

aptalca commented 4 years ago

Good find. It is strange that the plugin gets its absolute real path, rather than the symlinked path.
