* Don't render blog archive pages unless a page is added/removed. Just
|
|
changing a page doesn't affect the archives as they show only the title.
|
|
|
|
* Look at splitting up CGI.pm. But note that too much splitting can slow
|
|
perl down.

|
* The backlinks code turns out to scale badly to wikis with thousands of
|
|
pages. The code is O(N^2)! It's called for each page, and it loops
|
|
through all the pages to find backlinks.
|
|
|
|
Need to find a way to calculate and cache all the backlinks in one pass,
|
|
which could be done in at worst O(N), and possibly less (if they're
|
|
stored in the index, it could be constant time). But to do this, there
|
|
would need to be a way to invalidate or update the cache in these
|
|
situations:
|
|
|
|
- A page is added. Note that this can change a backlink to point to
|
|
the new page instead of the page it pointed to before.
|
|
- A page is deleted. This can also change backlinks that pointed to that
|
|
page.
|
|
- A page is modified. Links added/removed.
