[12:36:24] Hey there. Does anybody have any idea what WMF-specific PHP config setting(s) might be causing preg_match to be buggy? https://phabricator.wikimedia.org/T340068 I have absolutely no clue what this is about [12:36:59] Or if somebody know who the right people to ask would be... [13:00:43] Daimona: FWIW, I installed php7.4-cli from https://wikitech.wikimedia.org/wiki/APT_repository in a docker container and could reproduce the issue [13:00:54] so it seems to be due to our packages, rather than the config in /etc [13:01:13] Oh, interesting, thank you. I didn't try that [13:02:10] Still wondering what on earth could be causing this, but this is a good start [13:04:20] i added some tags to the task, hopefully will catch attention of some people who can help. [13:04:22] good catch Lucas_WMDE :) [13:04:36] Daimona: "Bytes in the string which are not valid UTF-8, and UTF-8 characters which do not exist in ISO-8859-1 (that is, characters above U+00FF) are replaced with ?." [13:04:54] so that it is exactly U+00FF ... is indeed very suspicious [13:04:59] that means it is 2 bytes [13:05:29] comments on https://stackoverflow.com/questions/66723146/utf8-encoding-issue might give hints maybe [13:06:20] Daimona: yes, the "serviceops" tag is what I would have recommended too [13:06:52] Thanks! In a meeting rn, I'll take a look later [13:08:48] also you can try Moritz M. / infra-security since afaik he is building the packages
