Nested Pages

It's now possible to create wiki pages inside other wiki pages. More specifically we've decided to drop the concept of Space in the UI (it's still there at the API/platform level) and instead, to replace it with the concept of Nested Pages.

We've also decided to drop the concept of Parent/Child relationship since it was too complex for end users to have 2 hierarchies: the Space/Page hierarchy and the Parent/Child hierarchy. The Parent/Child hierarchy also had limitations: you couldn't inherit page permissions for example. Thus the idea is to have a single hierarchy based on Nested Pages.

Advantages of Nested Pages:

  • The URL reflects the page hierarchy
  • Finer-grained control: Ability to set permissions at each level
  • Generally speaking, a nicer and simpler way to organize your content hierarchically
  • Moving and Deleting pages updates the hierarchy

Terminology:

  • Nested Page (a.k.a Non-Terminal Page): This is a wiki page that can have children pages. Technically a Nested Page is implemented as a Nested Space (i.e. a WebHome page).
  • Non-Nested Page (a.k.a Terminal Page): This a wiki page that cannot have children pages. Applications and script can create Terminal Pages. Advanced Users will also be able to create Terminal Pages from the UI. Standard Users will only be able to create Nested Pages.
  • Nested Space: A Space which has another Space as parent. As mentioned above, a Nested Page is technically implemented as a Nested Space. You will used the term Nested Space when speaking technically about XWiki APIs for example but when talking about UI you should favor using the term Nested Page instead.

Script right

A new Script Right has been added to allow controlling who has the right to write Scripts. Specifically anyone with Edit rights can edit a page and write a Script in it. However, when the page is rendered the script will only execute if the last author of the page has the Script right.

Example when the author of a script doesn't have the Script right:

Performances tests compared to 6.4.5

There hasn't really been much performance work on this version so we get mostly the same result than in 7.1 release note. The important point here was to check if nested spaces ha much impact on performances.

Summary

"similar": difference is lower than 10%
"slightly": difference is lower than 20%

Note hat most of the speed related values are an average of very moving results, a lot of things is happening during a HTTP request and it's far from stable duration (that's why 10% may sounds a lot for something called "similar" but the variable can go up and down around 5% sometimes so 10% average is really not that much of a clear win).

Backward Compatibility and Migration Notes

General Notes

When upgrading make sure you compare your xwiki.cfg, xwiki.properties and web.xml files with the newest version since some configuration parameters may have been modified or added. Note that you should add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
