Test more packages before publishing a new release
Brief outline of the enhancement
Recently some packages broke after a new l3kernel
release had been out. Therefore I think it might be a good improvement to test more packages before publishing a new latex2e
(or l3kernel
) release.
Mr. Wright replied in https://github.com/lvjr/tabularray/issues/474#issuecomment-1946122548:
We've considered that before but it's not workable: changes in packages would lead to breakage we can't track, etc.
But after doing some experiments I think it is doable. Island of TeX provides weekly updated Docker images for latest full TeX Live. So we can run tests on them with GitHub Actions.
Step 0: Find out all .sty
and .cls
files in tex/latex
folder and compile them with pdflatex
on current TeX Live.
% for somename.cls file
\documentclass{somename}
\begin{document}
TEST
\end{document}
% for somename.sty file
\documentclass{article}
\usepackage{somename}
\begin{document}
TEST
\end{document}
Then add every package file which fails the compilation to an ignorelist
. (If you want to do more you could also consider tex/xelatex
and tex/lualatex
folders as well as xelatex
and lualatex
programs in the future.)
We only need to do Step 0 once. Now every time a new latex release is out, we need to do the following two steps:
Step 1: Do tests similar to Step 0, but we exclude package files in ignorelist
and record every success package file in a passlist
.
Step 2: Install the new latex release to TeXLive Docker image. And this time we only test files in passlist
. If a package file in passlist
fails the test, we are almost sure that it is caused by the new latex release.
