Description Mathieu Dubois-Briand 2026-02-12 12:34:42 UTC 
With recent changes on emptty, it appears to have some reproducibility issues. Happened quite a few times this week.

AssertionError: The following deb packages are different and not in exclusion list:
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-conf-dbg_1.0-r0_amd64.deb
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-conf-dev_1.0-r0_amd64.deb
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-conf_1.0-r0_amd64.deb
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-dbg_0.15.0-r0_amd64.deb
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-dev_0.15.0-r0_amd64.deb
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-doc_0.15.0-r0_amd64.deb
/srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/deploy/deb/./x86-64-v3/emptty-src_0.15.0-r0_amd64.deb

Diff can be seen here: https://valkyrie.yocto.io/pub/repro-fail/oe-reproducible-20260212-ssslvz6_/packages/diff-html/

I believe this is because of files modification time differing on /etc/emptty/conf and it's parent folders.

Not merged to master yet so invalid.
Mathieu will reply on list but I've CCed Randolf here too.
Comment 3 Randolph Sapp 2026-02-13 18:59:46 UTC 
Narrowed down the issue to get_source_date_epoch_from_git stopping at the first git directory it finds. Potential solution posted here: https://lists.openembedded.org/g/openembedded-core/message/231077
