Package: debci Severity: normal Hi! We generally expect build/autopkgtest log output to be plain text -- but a lot of new-fangled build/test systems decorate it with colors. Also, optimizing long runs of spaces into horizontal cursor movement is not unheard of.
Such pretty-printing got more popular these days, as common CI services such as Travis do support colors. debci webpages currently pass such escapes as unprintables to a http browser, one example: https://ci.debian.net/data/autopkgtest/testing/arm64/d/diaspora-installer/11276425/log.gz To fix that, you could filter the logs through a converter such as ansi2html (if colors are welcome) or ansi2txt (if not). As discussed on IRC, it would be far cheaper to do such a conversion on-the-fly when a particular log is requested, as the vast majority of logs never get read.
