DavCache 1.0b3 released

[mnasato]

Hi folks,

The third beta of DavCache has been released on labs

http://labs.jboss.com/davcache

DavCache is a WebDAV interface to JBossCache, originally an idea from Bela

http://jira.jboss.com/jira/browse/JBCACHE-332

With a WebDAV frontend JBossCache can be used as
* a simple distributed filesystem; copy a file to one WebDAV location and it will instantly replicated to all nodes in the cluster
* the foundation for a clustered CMS application

This release features

* bugfixes and improved WebDAV compliance
* a very simple CMS example included in the webapp
* some documentation on the wiki

Comments are very welcome.

Thanks

Mirko

Great stuff ! I had some problems though with using a FileCacheLoader: when I copied some files into the webdav dir, everything was replicated correctly, plus the entries in the dir (C:\\tmp) were created correctly.
However, when I created a folder in the dav dir, e.g. dav/docs, then all top level documents were deleted !

I also looked at the CMS, cool stuff ! You should write an article about this !

Thanks Bela!

Baffling... I couldn't reproduce it. You're starting 2 jboss nodes on the same machine, with CacheLoaderShared = true in the TreeCache configuration, right?

Cool indeed! For the distributed file system, we can offer cache side transactionability already. If we can build streaming on top (for big file size), that would open for new door. :-)

Yes, I ran 2 instances with a FileCacheLoader pointing to c:\\tmp and CacheLoaderShared set to true.
Try to copy some files into the webdav drive, then create a docs directory. When you restart both, the top level files are gone, but the 'docs' dir is still there...

Did a few more tests with FileCacheLoader on Windows but had no luck in reproducing the problem.

Only weird thing I noticed is that sometimes Explorer needs a forced refresh otherwise it'll display an out of date file listing.
