VersioningFileProvider is a new PageProvider, meant to replace the RCSFileProvider, which has problems especially with Windows.Hey

It is available from JSPWiki 1.7.0 onwards.

see also FileProviderComparing, FileProviderMoving

Is the VersioningFileProvider now workable on Windows?

How do I go about using it / testing it?


It should be quite functional. Just do the following:

  1. Open file in your favorite editor
  2. change the jspwiki.pageProvider property to VersioningFileProvider (the former version of this page called for "com.ecyrd.jspwiki.VersioningFileProvider").
  3. a few lines below you have to set the directory where the VersioningFileProvider stores its files. Just change the property jspwiki.fileSystemProvider.pageDir according to the file and directory naming conventions...

Now you should be set (at least for version 2.0.0 alpha).


I seem to remember a Java port of the CVS client, I wonder if that had a diff client that could be re-used...


Since 1.8.0, we are using an internal Java diff routine, so we now require no other software =).


Setting a maximum number of versions to store?#

Something that might be useful would be a property that can be set expressing the maximum number of revisions stored. If this value were set to 10, then when the 11th version were added it could automatically delete the first. I suppose the rest of the files could be then renamed (2 to 1, 3, to 2, etc) but I'm not sure I see much need for that. That might reduce some of the administration necessary. I don't see a whole lot of interest with maintaining the ability to go back to the absolute first version of something. I find that being able to back a few to maybe a dozen is sufficient, but YMMV, I suppose.

Nice idea. It would make sense to enable something like that for intranet wikis and so on; on public wikis you really want rollback to any version (to make sure you can get over from WikiGraffiti).

When I try to use VersioningFileProvider on my wiki, the system gave me

an error that An unknown exception java.lang.NullPointerException was caught by Error.jsp#

Who has idea why it is?

Hi ... even i am having the same problems with it

An unknown exception java.lang.NullPointerException was caught by Error.jsp

does anybody know whats happening??


Arite ... the null pointer exception is now solved... u need to do the following:

1. jspwiki.pageProvider = VersioningFileProvider

2. jspwiki.fileSystemProvider.pageDir = path where all the wiki pages are... it creates a subdirectory here for storing the older versions...

jspwiki.versioningFileProvider.pageDir = some path

and it works fine for me ...

But can someone tell me if you have managed to get the AntCvsFileProvider running fine with the latest version of JSPwiki?? thanks
