From 05e96e96a315fa49faca4da2aedd1761a218b616 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 16 Mar 2023 00:50:18 +0900 Subject: kbuild: use git-archive for source package creation Commit 5c3d1d0abb12 ("kbuild: add a tool to list files ignored by git") added a new tool, scripts/list-gitignored. My intention was to create source packages without cleaning the source tree, without relying on git. Linus strongly objected to it, and suggested using 'git archive' instead. [1] [2] [3] This commit goes in that direction - Remove scripts/list-gitignored.c and rewrites Makefiles and scripts to use 'git archive' for building Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg' use 'git archive' again. Going forward, building source packages is only possible in a git-managed tree. Building binary packages does not require git.

I wrote a patch [1] to make it work in most cases, but still wonder if this is what we should aim for. To simplify the code, this patch just gives up untracked files. Going forward, it is your responsibility to do 'git add' for what you want in the source package. The script shows a warning just in case you forgot to do so. It should be checked only when building source packages.
