Review: openexr 3.5.2+ds-1

Package Information

Description	runtime files for the OpenEXR image library OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. OpenEXR's features include: * Higher dynamic range and colour precision than existing 8- and 10-bit image file formats. * Support for the "half" 16-bit floating-point pixel format. * Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain. * Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications. This package contains the OpenEXR libraries.

DFSG Assistant LLM REVIEW 0 blocker, 0 important, 2 minor

This is an LLM based review using a Debian Inference based workflow. It was not written by a member of the DFSG team and has not been checked by one. It is not a decision on the package: it may be wrong, and it may have missed things.

DFSG NEW review for openexr version 3.5.2+ds-1

Summary

Licensing is DFSG-compliant and debian/copyright is accurate: Yes
Packaging is of good quality: Yes
Issues: 0 blocker, 0 important, 2 minor
debian/watch: version 5
debian/copyright: machine-readable
Scan before the review: 52 found (11 not listed by the scan, so not checked)

Licensing

The tree is uniformly BSD-3-clause. A tree-wide SPDX/Licence grep found only one non-BSD file, src/wrappers/python/openexr_skbuild_plugin.py (Apache-2.0, from MaterialX), which debian/copyright declares with the full Apache-2.0 text. The Files: * catch-all and the named-holder stanzas (Industrial Light & Magic/ASWF/Contributors, DreamWorks, Pixar, Weta Digital, Autodesk, OpenColorIO, MaterialX) match the copyright headers of the files they cover, which I spot-checked. debian/copyright is DEP-5 machine-readable. The .exr files flagged by the prescan are test data (source-form fixtures), not built objects. The DreamWorks DWA patent grant in PATENTS restricts only the optional patent licence, not copying/modification/distribution, so it is not a DFSG problem.

Packaging

Packaging is sound: compat 13, dh with cmake, hardening=+all, correct Build-Depends (all exist in the archive), Standards-Version 4.7.4 (current), sane binary split with Multi-Arch, SONAME-based soname Provides via substvars, a working autopkgtest, and clean repo metadata. Two minor issues: the openexr package installs several command-line tools without man pages, and libopenexr-doc retains stale sphinx-common/libjs-jquery Depends after the HTML docs were dropped.

Issues

minor packaging 1. Six installed OpenEXR tools have no manual page ◂

Files: debian/openexr.manpages, debian/manpages/
Basis: checked, in the package or with a reference tool
Evidence: openexr.manpages installs only debian/manpages/*.1 (exrheader, exrenvmap, exrmakepreview, exrmaketiled, exrstdattr), while src/bin/CMakeLists.txt installs 11 tools (OPENEXR_INSTALL_TOOLS default ON); openexr.install ships usr/bin.
Problem: Policy 12.1: “Each program, utility, and function should have an associated manual page… considered as a bug”. exr2aces, exrinfo, exrmanifest, exrmetrics, exrmultipart and exrmultiview ship without any man page. Upstream generates man pages via help2man when OPENEXR_INSTALL_DOCS is set, but the Debian build leaves it off.
Fix: Either enable OPENEXR_INSTALL_DOCS (requires help2man build-dep) and install the generated man pages, or add hand-written pages for the six missing tools.

minor packaging 2. libopenexr-doc has stale sphinx/query doc Depends ◂

Files: debian/control
Basis: checked, in the package or with a reference tool
Evidence: Depends: libjs-jquery, sphinx-common, ${misc:Depends} on libopenexr-doc, which now ships only usr/share/doc/OpenEXR/examples/* (per libopenexr-doc.examples); the changelog records “Drop html docs” in 3.4.6.
Problem: The package no longer ships HTML documentation, so the sphinx-common and libjs-jquery runtime Depends are unnecessary and pull in unrelated packages.
Fix: Drop sphinx-common and libjs-jquery from libopenexr-doc's Depends (keep ${misc:Depends}).

Verified ◂

Tree-wide SPDX/Licence grep (with gitignore:false) shows every header is SPDX-License-Identifier: BSD-3-Clause; the sole non-BSD SPDX is src/wrappers/python/openexr_skbuild_plugin.py (Apache-2.0), correctly declared in debian/copyright with the common-licenses pointer.
Spot-checked the headers of the files named in the named-holder stanze of debian/copyright: ImfSimd.h (Autodesk), ImfPxr24Compressor.h (Pixar), ImfMultiView.h (Weta), ImfDwaCompressor.h / internal_dwa.c / testRle.cpp / ImfSystemSpecific.cpp (DreamWorks), FindPythonPackage.cmake (OpenColorIO), openexr_skbuild_plugin.py (MaterialX, Apache-2.0) — all match the Copyright holders and BSD-3-clause licence in their stanzas.
Files-Excluded: external is honoured: there is no external/ directory in the unpacked tree.
The prescan 'rare wording' hit website/news.rst:846 (“evaluation purposes only”) is a news announcement about an unstable branch, not a licence term — not an issue.
The prescan holder hit “Industial Light & Magic” in website/test_images/ScanLines/*.rst matches “Industrial Light & Magic” named in the Files: * stanza.
All .exr files flagged as binary data (src/test/OpenEXRTest/*.exr, src/test/bin/test_images/*.exr, python tests/*.exr) are test/data fixtures, the preferred form for such data, covered by the BSD-3 Files: * stanza — not an issue.
No minified JS, .jar/.class/.so/.dll/.exe/.pyc, font, PDF or other built artefact lacking sources found in the tree (glob for those extensions returned nothing).
PATENTS (DreamWorks DWA licence choice + patent grant) and LICENSE.md (BSD-3) reviewed; the patent terms constrain only the optional patent grant, not the copyright licence, so no DFSG problem.
debian/copyright begins with the correct DEP-5 Format line and has a full standalone BSD-3-clause text; all licences used (BSD-3-clause, Apache-2.0) are DFSG-free and mutually compatible.
Packaging: Build-Depends (cmake, debhelper-compat 13, libdeflate-dev, libimath-dev>=3.1.2, libopenjph-dev, libzstd-dev, pkgconf, zlib1g-dev) all exist in the archive; compat 13 substvar/shlibs handling and the dio-nocheck override are correct for this compat level; override_dh_makeshlibs builds the Imath-suffixed soname Provides; autopkgtest builds and runs the writer/reader example against the installed lib.
uscan found the packaged version as the newest upstream release (upstream 3.5.2, packaged 3.5.2+ds).
Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (Apache-2.0).

Not confirmed ◂

Could not build or run the package, so nothing further was verified about the shlibs/Provides name for a specific installed Imath soname at compile time; the mechanism is inherited from the previously-uploaded 3.4.x release.

Proposed changes ◂

None.

Uploader's response to the LLM review

I won't argue with an LLM. "I want to talk to your manager" :-)

Final Comment

Hi,

To be clear: that response comment is for the human reviewer, and the LLM doesn't get to see it unless it's made some completely egregious mistake and needs some refinement to it's instructions to reduce the odds of that happening again.

Perhaps I should tweak the wording to make that clear...

Something the LLM can be pretty decent at is writing manpages though :-)

Thanks!
