Reproducible Builds/Status

Arch Linux is constantly rebuilding core and extra packages and has a status page. This page contains a status of bad packages and what needs to be fixed.

Issues

General

  • A rebuild is required for all packages build with pacman < 5.2 to resolve file order issues and a btrfs size bug. For the file order issue the affecting extra packages can be found running the following one liner on a mirror directory:
for i in /srv/ftp/extra/os/x86_64/*.pkg.tar.??; do
   bsdtar -tf $i | grep "^\." > pkg-order
   sort pkg-order > sort-order
   if ! diff pkg-order sort-order &>/dev/null; then
     echo $i;
   fi
   rm pkg-order sort-order
done

Packages with JAR files

JARs include a modification timestamp for each file, making them unreproducible. Depending on the build system, there are different solutions available for this.

Ant

Currently has no support for reproducible builds, see the upstream feature request.

Gradle

Should support reproducible builds out of the box.

Maven

Supports the project.build.outputTimestamp property that can be set to a fixed timestamp. Recent versions of Maven plugins respect this property to create reproducible artefacts. The property should be set in the project's pom.xml file, if upstream does not already do this, you can define it at compile time using a command like

mvn -Dproject.build.outputTimestamp="$SOURCE_DATE_EPOCH" clean package

It might be necessary to patch the project's pom.xml to update plugins to a more recent version with support for reproducible builds, see the Maven guide to reproducible builds for the minimum required versions and more information like additional necessary configuration options.

Example package (including a patch for a Maven plugin version update): junit-system-rules.

OpenJDK jar command

The builtin OpenJDK jar program will support SOURCE_DATE_EPOCH starting with OpenJDK version 15.

strip-nondeterminism

As a last resort, strip-nondeterminism from Debian is able to strip unreproducible metadata like file timestamps from a variety of file types, including JARs. It is not a cure-all (e.g. build systems might include additional unreproducible metadata in the JAR manifest, strip-nondeterminism removes some, but not all of these) and should only be used as a last resort if no native support for reproducible builds is available:

strip-nondeterminism --timestamp "$SOURCE_DATE_EPOCH"

Example package: pdftk.

KDE Kdeveloper project files

KDE creates Package App template .tar.bz2 files which tar files and userid is different when reproducing with repro which might be a bug in repro. https://gist.githubusercontent.com/jelly/570313f56ee59be7674ad4cc002232e7/raw/b85536690c48b23ce97650e8db8f0ca18c2dbf1a/gistfile1.txt

The cmake file which generates the issue.

Doxygen documentation build with graphviz-2.44.0-2

graphviz lacked a dependency on libpng, making PNG generation unavailable in dot as graphviz was installed before libpng was available and therefore not marking it as to be dlopen'd. All packages which depend on doxygen for generation documentation and with the following diff require a rebuild.
