Hello, Am Mittwoch, 17. Februar 2016 schrieb Bernhard M. Wiedemann:
now I had some time to look into how reproducible our builds are and had a VM (with 4 cores) build all Leap 42.1 packages named a*
using some helper scripts, which I uploaded to https://github.com/bmwiedemann/reproducibleopensuse
with those helpers, I just had to do rebuildmany a* comparemany a*
btw: the rebuild of those 217 packages took 382 minutes
of those 217 (a small subset of Leap's 7830), build-compare reported a diff for 36 packages

I just checked the Debian result for some of them on https://tests.reproducible-builds.org/reproducible.html and interestingly, several of the packages you listed above are reproducible on Debian: acct, aegisub, aespipe, anthy, apel, asl, aspell, autogen, avogadro, avrdude. I know the reproducible builds team at Debian is actively pushing patches to make the build reproducible, but I'm not sure if they were able to fix that many packages already (10 out of 36 - actually I should probably say 10 out of ~25 because some of the packages you listed don't exist in Debian, at least not with this name). Can you upload the differences for the packages you tested somewhere so that interested people don't need to rebuild everything just to get the diff? Oh, BTW - maybe having some variables in your scripts instead of hardcoded paths would be nice ;-) I was curious and tried with aspell. The compare result is: /dev/shm/reproducibleopensuse/openSUSE:Leap:42.1/aspell/binaries /dev/shm/reproducibleopensuse/openSUSE:Leap:42.1/aspell /dev/shm/reproducibleopensuse/openSUSE:Leap:42.1/aspell Comparing aspell-0.60.6.1-18.4.x86_64.rpm to aspell-0.60.6.1-0.x86_64.rpm comparing rpmtags --- /tmp/tmp.2P0iOiEtHL/tmp.jsMGUlvr4J 2016-02-17 21:34:31.060962628 +0100 +++ /tmp/tmp.2P0iOiEtHL/tmp.5h81k6Lq48 2016-02-17 21:34:31.068962571 +0100 @@ -9,7 +9,7 @@ has many other technical enhancements over Ispell, such as using shared memory for dictionaries and intelligently handling personal dictionaries when more than one Aspell process is open at once. - openSUSE openSUSE Leap 42.1 obs://build.opensuse.org/openSUSE:Leap:42.1/standard/dd3d6bcef5a4f7fe0ae04047dd14a214-aspell GFDL-1.1+ and LGPL-2.1 and HPND and SUSE-BSD-Mark-Modifications GFDL-1.1+ and LGPL-2.1 and HPND and SUSE-BSD-Mark-Modifications + openSUSE openSUSE Leap 42.1 (none) GFDL-1.1+ and LGPL-2.1 and HPND and SUSE-BSD-Mark-Modifications GFDL-1.1+ and LGPL-2.1 and HPND and SUSE-BSD-Mark-Modifications Productivity/Text/Spell http://aspell.net/ (none) (none) (none) (none) 4.11.2 x86_64-suse-linux cpio lzma 5 comparing RELEASE comparing PROVIDES comparing scripts comparing filelist comparing file checksum creating rename script RPM meta information is identical Extracting packages Package content is identical [...same for other subpackages...] It seems the only difference is in the rpmtags - (none) vs. obs://build.opensuse.org/openSUSE:Leap:42.1/standard/dd3d6bcef5a4f7fe0ae04047dd14a214-aspell Is this really a relevant difference, or should it be whitelisted in build-compare? Hmm, actually $?=0, so on my system it _is_ reproducible. What did I do wrong? ;-) I also tried aespipe, and get a real difference. Maybe someone should compare the openSUSE package with the Debian package to find out what they do different to make the package reproducible ;-) Regards, Christian Boltz --
