Description

This scope of this tracking task is somewhat specific to Wikimedia, however the sub tasks that resolve this use case will benefit all MediaWiki installs.

When upgrading a wiki from one wmf-branch to the next, we currently invalidate almost all static caches for front-end resources.

  • Server-side HTTP response cache (Varnish).
  • Client-side HTTP response cache (Web browsers, proxies).
  • Client-side module storage (e.g. HTML5 Storage, see ResourceLoader#Client storage).

Source of invalidation:

  • Bad input for file module definition hashes:
    • T104950: File module versions bump due to increase of timestamps (new git clone)
    • Stylesheet content changes due to use of timestamps in CSSMin.
    • Inclusion of localBasePath (absolute path on-disk that contains the MediaWiki branch version).
    • Inclusion of remoteBasePath (absolute url that contains the MediaWiki branch version).
  • T99096: /static-{branch} urls to mount static files. The branch changes each deployment. Ironically, these are currently cached too long (T99096). We need to find a way to cache them even longer, and bypass it when they change.
  • LocalisationUpdate: Invalidates message cache every time and bumps the timestamp. Invalidates all modules with one or more messages.
  • ..

Example: Graph showing impact of deploying a new MediaWiki branch to Wikipedias on ResourceLoader caching of each week over the past month.

While T104950 was resolved (in that it no longer uses timestamps) file modules still appear to roll over en-mass during a branch cut. Looking at the graphs we can clearly see the problem wasn't fixed. Just today another branch update metrics such as 304 Satisfaction drop to the floor:

@Krinkle mentioned this in rMW6a78b4811df2: resourceloader: Remove remoteBasePath from FileModule version hash

That still didn't nail it. Still trashing versions of most file modules.

The funny thing is that when switching it's alternating inconsistently. It's not that the extra hash was added or removed in wmf20. It's some kind of oscillation bug. In the paste above for example, it changed from f1Ifa cB to eqAznAKY whereas originally (in the startup-diff paste) it changed from eqAznAKY to f1Ifa cB.

The last blocking task is T113916: Switch ResourceLoader file dependency tracking to MultiDC-friendly backend. However closing this as the resolved since the original goals have been achieved without it.

  • Static files. T99096: We fixed our static url scheme to not change every week. Whilst also addressing the need for longer cache expires and more stable urls overall.
    • Previously, url urls varied by weekly branch name. This meant they were cached too long (if we want to change something mid-week), and too short (needlessly invalidates browser cache the same day every week for many files that haven't changed).
    • Solution:
      • Add a query string to the url with a content hash. This means cache will instantly roll-over when a change is deployed.
      • Unify the virtual /static* directory structure to be branch-agonistic. This was done by developing the /w/static.php proxy in wmf-config (source code), which, baed on the content hash, will find the file from a deployed branch. This means urls will not become 404 if they are cached in HTML content for longer than a week (fixes T99096). And it means we now make better use of web browser caching by not needlessly changing the url every week.
  • Module versions. We fixed all the different factors that caused the module hash to change when no actual change was made to the effective script content. (T98087, T104950, T94810, T94074)

Nonetheless, T113916 remains as separate technical debt.
