[Phpwiki-talk] On the fly ZIP snapshot.

[Jeff D. <da...@da...>]

I've just checked in to the CVS the beginnings of on-the-fly ZIP file
creation.  To use, just click on the link near the bottom of admin/index.php3.

Current Features:
   o If PHP has zlib compiled in, pages are compressed (deflated).
     (If PHP doesn't have zlib, pages are just stored --- also ZIP production
      is quite a bit slower on account of CRC32 computation in PHP.)
     (And I've just discovered that my web hosts PHP doesn't have zlib :-/)

   o Page meta-data (author, version, etc...) is saved in a special custom
     header field in the zip file.   This information is not accessible via
     any standard zip tools, but I plan on writing an unzipper which can
     use this information to restore a Wiki from the zip file.  (The zip file
     is (should be) still readable using any unzipper.)

   o Currently, only the most recent version of a page is archived.
     If this is an issue, we can easily add an option for including 
     all saved versions of every page.
      
Known Issues:
   o Speed and volume of output might be an issue for large Wikis (especially
     when PHP doesn't have zlib support).   Certainly the PHP execution timeout
     should be increased.

   o I still need to write the unzipper.

What's the concensus?  Is this cool or just overkill?
