kohana-sabredav

Basic Kohana (3.3.1) module wrapping sabredav (1.8.7)

  • This is a work-in-progress
  • Only testing Webdav (for now) involving file transfer (using CyberDuck client)
    • Upload (PUT) - *.php files still problematic
    • Upload (POST)
    • List (PROPFIND)
    • Rename (MOVE)
    • Delete (DELETE)
  • Use Kohana Auth as a Authentication plugin (enable in config/sabredav.php)
  • Serve up one directory per user (appends username to root directory)
  • TODO: Test CardDav, CalDAV, etc.
  • TODO: Set up submodule for fruux/sabre-dav (current this is checked in)
  • TODO: Make stashing the Response HTTP Status into a plugin. Currently, this is a HACK (edited Sabredav code) in Sabre\HTTP\Response class to stash the status code in a member variable so we can get it later from Kohana. Also stashing the body the same way (not used)

This module does the following basic things:

  • Creates an init.php for Kohana to load up the proper classes
  • Creates a demo Route and Controller (not secure)

Install

  • Download or clone and put into the /modules folder

Configure

  • Enable in bootstrap.php
...
Kohana::modules(array(
  ...
    'sabredav' => MODPATH.'kohana-sabredav',
    ...
  ));
  ...
  • Copy /modules/kohana-sabredav/config/sabredav.php to /application/config/sabredav.php
  • Change some of the settings to point to a suitable folder

Test

Per the Sabre documentation Getting Started (https://code.google.com/p/sabredav/wiki/GettingStarted#Client_Setup) pull up in a browser http://example.com/webdav (demo Route and Controller) and you should see the error message per the documentation.

  • You can then use Cyberduck Webdav client to test further

Nginx Notes

A common optimization in Nginx is to cache static files using something like this

location ~* \.(js|css|png|jpg|jpeg|gif|ico|woff)(\?ver=[0-9.]+)?$ {
    expires 30d;
}

This will interfere with PUT (file upload) requests with those file extensions so you need to change it to specific folders only. For example, all your static assets are under a folder called /media/

location /media/ {
    location ~* \.(js|css|png|jpg|jpeg|gif|ico|woff)(\?ver=[0-9.]+)?$ {
        expires 30d;
    }
}

Notes

  • Had to create a Response class to include all the Webdav allowed HTTP Status codes
  • Had to implement a Lock Plugin specific to Kohana due to the php://input issue (same with PUT)
