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_me…
(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?
Greg
