Hello all, Background and longer/more detailed discussion on this issue is in bug 44570: https://bugzilla.wikimedia.org/show_bug.cgi?id=44570
Summary: As we delete old -wmfX branches there appears to be cached pages that reference old branch URLs, eg: https://bits.wikimedia.org/static-1.21wmf1/skins/common/images/poweredby_mediawiki_88x31.png (that 404s because 1.21wmf1 is long gone) If you want to see my bad ASCII art representation of our current caching layers, see this page: http://wikitech.wikimedia.org/view/Caching_overview So possible ways forward ======================== option 1: * reduce parsercache timeout to size of deployment window (~28 days) [0] * Tim may have knowledge why that shouldn't happen [1] option 2: * change away from version numbers in URLs [2] ** maybe use slots or something else ** skins? option 3: * status quo What do you think?
