For the build of that version and the next (1.19.0.5ubuntu2.1), the 'configure' file was correctly recreated during build. However at version 1.19.0.5ubuntu2.2, the 'configure' file was not recreated during build. Thus, dpkg was not built linked against libzstd. This regresses the ability of dpkg to uncompress zstd-compressed packages, unless the zstd utility is installed on the local system. Since dpkg does not list the zstd package as a dep, it may not be installed on all users' systems who want to install a zstd-compressed package. [test case] on bionic system: $ sudo apt install ubuntu-dev-tools $ pull-lp-source dpkg 1.19.0.5ubuntu2.2 $ cd dpkg-1.19.0.5ubuntu2.2/ $ sudo apt build-dep . $ dpkg-buildpackage and verify if dpkg-deb is linked against libzstd: $ ldd build-tree/dpkg-deb/dpkg-deb | grep zstd or extract it from the deb itself and check: $ dpkg-deb -x ../dpkg_1.19.0.5ubuntu2.2_amd64.deb ../deb-files $ ldd ../deb-files/usr/bin/dpkg-deb | grep zstd simply touching the 'configure.ac' file (to bring its timestamp newer than the 'configure' file) causes the build to work correctly: $ mkdir no-touch $ cd no-touch $ dpkg-source -x ~/dpkg_1.19.0.5ubuntu2.2.dsc $ cd dpkg-1.19.0.5ubuntu2.2/ $ dpkg-buildpackage $ ldd build-tree/dpkg-deb/dpkg-deb | grep zstd $ $ mkdir touch $ cd touch $ dpkg-source -x ~/dpkg_1.19.0.5ubuntu2.2.dsc $ cd dpkg-1.19.0.5ubuntu2.2/ $ touch configure.ac $ dpkg-buildpackage $ ldd build-tree/dpkg-deb/dpkg-deb | grep zstd libzstd.so.1 => /usr/lib/x86_64-linux-gnu/libzstd.so.1 (0x00007f8c1d8af000) [regression potential] this forces autoreconf to be run for each build, which may add some small amount of time to the build. Other than that, the regression potential seems small, since autoreconf should be getting run for each build, and was for most (but not all) builds. Any regression would almost certainly involve a failure to build the package, or a failure to pick up new configure.ac changes correctly. [other info] this might not be an issue specifically with dpkg itself, it could be an issue with debhelper and other tooling that is responsible for calling autoconf or autoreconf during build. Or possibly a problem with the dpkg debian/rules or other related build config. Or, simply including the 'configure' file in the package source might be considered a bug, since it's an intermediate build file that really shouldn't be included. However, it's included in many source packages, including in debian, and removing it from all of them seems unlikely and/or unwieldy. Additionally, for "normal" packages that use quilt (i.e., aren't native), any changes to the 'configure.ac' file would be done with a patch, meaning the pre-build process would always make the 'configure.ac' file newer than the 'configure' file. Maybe for native packages, autoconf/autoreconf should always be called with -f, or maybe the 'configure' file should be removed from native packages.
