Since +inline (and other plugins) explicitly add all linked pages, each as a +separate item, the list can get rather long, and that single add_depends +loop has suddenly become O(N^2) to the number of pages, which is something +to avoid.. + +Also, since a lot of places are calling add_depends in a loop, it probably +makes sense to just make it accept a list of dependencies to add. It'll be +marginally faster, probably, and should allow for better optimisation +when adding a lot of depends at once. + +In Render.pm, we now have a triply nested loop, which is a bit +scary for efficiency. It seems there should be a way to +rework this code so it can use the optimised `pagespec_match_list`, +and/or hoist some of the inner loop calculations (like the `pagename`) +out. + +Very good catch on img/meta using the wrong dependency; verified in the wild! +(I've cherry-picked those bug fixes.) + [[!tag wishlist patch patch/core]] |
