One of the CSS resource loader URL yield content which is gzipped twice :-( The content is shown by piping to gzcat twice: curl 'http://bits.beta.wmflabs.org/en.wikipedia.beta.wmflabs.org/load.php?debug=7Cext.uls.nojs%7Cext.visualEditor.viewPageTarget.noscript%7Cext.wikihiero%7Cmediawiki.legacy.commonPrint%2Cshared%7Cmediawiki.skinning.interface%7Cmediawiki.ui.button%7Cskins.vector.styles%7Cwikibase.client.init&only=styles&skin=vector&*'|gzcat|gzcat Headers: > User-Agent: curl/7.30.0 > Host: bits.beta.wmflabs.org > Accept: */* > < HTTP/1.1 200 OK * Server Apache is not blacklisted < Server: Apache < Access-Control-Allow-Origin: * < Expires: Mon, 28 Jul 2014 09:22:53 GMT < X-Content-Type-Options: nosniff < Content-Encoding: gzip, gzip < X-Powered-By: HHVM/3.3.0-dev < Cache-control: public, max-age=300, s-maxage=300 < Vary: Accept-Encoding < Last-Modified: Thu, 24 Jul 2014 03:43:51 GMT < Content-Type: text/css; charset=utf-8 < Content-Length: 24050 < Accept-Ranges: bytes < Date: Mon, 28 Jul 2014 09:19:08 GMT Same goes on when passing Accept-Encoding: gzip I restarted varnish on the bits cache to clear up the bits cache, hasn't solved anything. The minified CSS cache key is enwiki:resourceloader:filter:minify-css:7:e07e6ad07840d291e66cf3fe9f0980c3
Proper command: curl 'http://bits.beta.wmflabs.org/en.wikipedia.beta.wmflabs.org/load.php?debug=7Cext.uls.nojs%7Cext.visualEditor.viewPageTarget.noscript%7Cext.wikihiero%7Cmediawiki.legacy.commonPrint%2Cshared%7Cmediawiki.skinning.interface%7Cmediawiki.ui.button%7Cskins.vector.styles%7Cwikibase.client.init&only=styles&skin=vector&*' | gzcat | gzcat ** yields some CSS **
Niklas reported it to be fixed in Vagrant: hhvm: set GzipCompressionLevel = 0 to avoid double-gzip https://gerrit.wikimedia.org/r/#/c/145771/ Which was bug 67928
Fixed in 4bdfea04cea2e54e6076a1c6b955ba1e1b51209f.
