Re: Issues with Wiki Dump and Garbage in page_data

Hi Harold,

With the modification introduced in Subversion 10904, accessing a non-existent page should no longer create a file in page_data directory.
Please test it is working for you.

I expect to publish PhpWiki 1.6.1 soon.

Best regards,

Marc-Etienne

Done! Actually, the method of my previous updates was pretty poor, and I ended up with nested versions. So, it was difficult to tell what version was actually running. I have now just unzipped version 10904, renamed it, and copied over my old config.ini after comparing it with config-dist to see what changes needed to be made. It appears to be working!

So, back to the original question. Are files now created in page_data and ver_data when a nonexistant page is requested? Again, my DB method is file. I have a lot of trash in those two directories.

I don't see an easy way of getting rid of the trash other than doing a dump of the wiki, deleting everything in those directories, then doing a respore. Is this a reasonable approach?

THANKS!

Harold
