Package: qhelpgenerator-qt5 Severity: wishlist Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: randomness X-Debbugs-Cc: reproducible-b...@lists.alioth.debian.org
Dear Maintainer, I'm an occasional contributor to Debian's reproducible builds, and noticed a recent reproducibility test failure[1] for the qtwebview-opensource-src source package that has a build-dependency on qhelpgenerator-qt5. The problem relates to a documentation file -- qtwebview.qch -- that is built by the qhelpgenerator binary. In particular, when qhelpgenerator collects items for a FileAttributeSetTable table in the .qch file -- which is a SQLite3 database -- it uses a QT QSet datastructure. Crucially, that datastructure does _not_ guarantee sort ordering (neither insertion-order nor key-order) when retrieving items, as documented[2]. I'll offer a patch shortly that adds a sort step, consistent with another similar sort that occurs within the same helpgenerator.cpp code file. In terms of testing: I've confirmed that the package compiles with my patch, and that the resulting qhelpgenerator-qt5 binary package can be used to build the src:qtwebview-opensource-src package and produces a qtwebview.qch file with the expected table records in the expected order. Thanks, James [1] - https://tests.reproducible-builds.org/debian/rb-pkg/trixie/arm64/qtwebview-opensource-src.html [2] - https://doc.qt.io/qt-5/qset.html
