[Bug 1217774] New: qt6-webengine qtpdf.index reproducible builds
https://bugzilla.suse.com/show_bug.cgi?id=1217774 Bug ID: 1217774 Summary: qt6-webengine qtpdf.index reproducible builds Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: All Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: screening-team-bugs@suse.de Reporter: bwiedemann@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: Development Blocker: --- While working on reproducible builds for openSUSE, I found that our qt6-webengine / qt6-webengine-docs-html subpackage varied between builds in /usr/share/doc/qt6/qtpdf/qtpdf.index See diff at https://rb.zq1.de/compare.factory-20230830/diffs/qt6-webengine-compare.out You probably need to build with osc build -M docs -- You are receiving this mail because: You are on the CC list for the bug.

So it could be some race-condition. Looking at https://rb.zq1.de/other/qt6-webengine/provenance.dot.svg there are 2 qdoc runs triggered by cmake --build build -j $N -t docs https://rb.zq1.de/other/qt6-webengine/ also has the raw strace output so you could check which other files were read or written by qdoc. Maybe it kept some shared cache. -- You are receiving this mail because: You are on the CC list for the bug.

At least I did not see any more variations in qtpdf.index -- You are receiving this mail because: You are on the CC list for the bug.
