                        Version 3, 29 June 2007
 .
  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  Everyone is permitted to copy and distribute verbatim copies
  of this license document, but changing it is not allowed.
 .
 .
   This version of the GNU Lesser General Public License incorporates
 the terms and conditions of version 3 of the GNU General Public
 License, supplemented by the additional permissions listed below.
 .
   0. Additional Definitions.
 .
   As used herein, "this License" refers to version 3 of the GNU Lesser
 General Public License, and the "GNU GPL" refers to version 3 of the GNU
 General Public License.
 .
   "The Library" refers to a covered work governed by this License,
 other than an Application or a Combined Work as defined below.
 .
   An "Application" is any work that makes use of an interface provided
 by the Library, but which is not otherwise based on the Library.
 Defining a subclass of a class defined by the Library is deemed a mode
 of using an interface provided by the Library.
 .
   A "Combined Work" is a work produced by combining or linking an
 Application with the Library.  The particular version of the Library
 with which the Combined Work was made is also called the "Linked
 Version".
 .
   The "Minimal Corresponding Source" for a Combined Work means the
 Corresponding Source for the Combined Work, excluding any source code
 for portions of the Combined Work that, considered in isolation, are
 based on the Application, and not on the Linked Version.
 .
   The "Corresponding Application Code" for a Combined Work means the
 object code and/or source code for the Application, including any data
 and utility programs needed for reproducing the Combined Work from the
 Application, but excluding the System Libraries of the Combined Work.
 .
   1. Exception to Section 3 of the GNU GPL.
 .
   You may convey a covered work under sections 3 and 4 of this License
 without being bound by section 3 of the GNU GPL.
 .
   2. Conveying Modified Versions.
 .
   If you modify a copy of the Library, and, in your modifications, a
 facility refers to a function or data to be supplied by an Application
 that uses the facility (other than as an argument passed when the
 facility is invoked), then you may convey a copy of the modified
 version:
 .
    a) under this License, provided that you make a good faith effort to
    ensure that, in the event an Application does not supply the
    function or data, the facility still operates, and performs
    whatever part of its purpose remains meaningful, or
 .
    b) under the GNU GPL, with none of the additional permissions of
    this License applicable to that copy.
 .
   3. Object Code Incorporating Material from Library Header Files.
 .
   The object code form of an Application may incorporate material from
 a header file that is part of the Library.  You may convey such object
 code under terms of your choice, provided that, if the incorporated
 material is not limited to numerical parameters, data structure
 layouts and accessors, or small macros, inline functions and templates
 (ten or fewer lines in length), you do both of the following:
 .
    a) Give prominent notice with each copy of the object code that the
    Library is used in it and that the Library and its use are
    covered by this License.
 .
    b) Accompany the object code with a copy of the GNU GPL and this license
    document.
 .
   4. Combined Works.
 .
   You may convey a Combined Work under terms of your choice that,
 taken together, effectively do not restrict modification of the
 portions of the Library contained in the Combined Work and reverse
 engineering for debugging such modifications, if you also do each of
 the following:
 .
    a) Give prominent notice with each copy of the Combined Work that
    the Library is used in it and that the Library and its use are
    covered by this License.
 .
    b) Accompany the Combined Work with a copy of the GNU GPL and this license
    document.
 .
    c) For a Combined Work that displays copyright notices during
    execution, include the copyright notice for the Library among
    these notices, as well as a reference directing the user to the
    copies of the GNU GPL and this license document.
 .
    d) Do one of the following:
 .
        0) Convey the Minimal Corresponding Source under the terms of this
        License, and the Corresponding Application Code in a form
        suitable for, and under terms that permit, the user to
        recombine or relink the Application with a modified version of
        the Linked Version to produce a modified Combined Work, in the
        manner specified by section 6 of the GNU GPL for conveying
        Corresponding Source.
 .
        1) Use a suitable shared library mechanism for linking with the
        Library.  A suitable mechanism is one that (a) uses at run time
        a copy of the Library already present on the user's computer
        system, and (b) will operate properly with a modified version
        of the Library that is interface-compatible with the Linked
        Version.
 .
    e) Provide Installation Information, but only if you would otherwise
    be required to provide such information under section 6 of the
    GNU GPL, and only to the extent that such information is
    necessary to install and execute a modified version of the
    Combined Work produced by recombining or relinking the
    Application with a modified version of the Linked Version. (If
    you use option 4d0, the Installation Information must accompany
    the Minimal Corresponding Source and Corresponding Application
    Code. If you use option 4d1, you must provide the Installation
    Information in the manner specified by section 6 of the GNU GPL
    for conveying Corresponding Source.)
 .
   5. Combined Libraries.
 .
   You may place library facilities that are a work based on the
 Library side by side in a single library together with other library
 facilities that are not Applications and are not covered by this
 License, and convey such a combined library under terms of your
 choice, if you do both of the following:
 .
    a) Accompany the combined library with a copy of the same work based
    on the Library, uncombined with any other library facilities,
    conveyed under the terms of this License.
 .
    b) Give prominent notice with the combined library that part of it
    is a work based on the Library, and explaining where to find the
    accompanying uncombined form of the same work.
 .
   6. Revised Versions of the GNU Lesser General Public License.
 .
   The Free Software Foundation may publish revised and/or new versions
 of the GNU Lesser General Public License from time to time. Such new
 versions will be similar in spirit to the present version, but may
 differ in detail to address new problems or concerns.
 .
   Each version is given a distinguishing version number. If the
 Library as you received it specifies that a certain numbered version
 of the GNU Lesser General Public License "or any later version"
 applies to it, you have the option of following the terms and
 conditions either of that published version or of any later version
 published by the Free Software Foundation. If the Library as you
 received it does not specify a version number of the GNU Lesser
 General Public License, you may choose any version of the GNU Lesser
 General Public License ever published by the Free Software Foundation.
 .
   If the Library as you received it specifies that a proxy can decide
 whether future versions of the GNU Lesser General Public License shall
 apply, that proxy's public statement of acceptance of any version is
 permanent authorization for you to choose that version for the
 Library.

DFSG NEW review for pyarcus version 5.3.0-1

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: nothing found

Licensing

All upstream files are Ultimaker B.V. work under LGPL-3 or later (each C/C++/sip file says 'pyArcus is released under the terms of the LGPLv3 or higher', and the top-level LICENSE is LGPL-3), debian/ is BSD-3-clause, and debian/copyright is DEP-5 with the correct short names, full BSD text and a pointer to /usr/share/common-licenses/LGPL-3. No non-free terms, no unlicensed file, no generated or binary-only file: the sip binding's C++ is generated from the shipped python/*.sip. The only inaccuracy is that the top-level pyproject.toml, which the Debian patch creates, is claimed in the Files: * stanza as Ultimaker's LGPL-3+ work.

Packaging

Modern and sound: debhelper compat 13, dh with pybuild and PYBUILD_SYSTEM=pyproject building the SIP module through its PEP 517 backend, all substvars present, autopkgtest 'import' present and consistent with python3-all-dev, DEP-5 copyright, Vcs-* and a sane changelog. The only quality faults are minor: the patch that adds pyproject.toml has no DEP-3 header, and the pyproject.toml it adds is misattributed in debian/copyright.

Issues

minor licensing 1. Files: * attributes the Debian-added pyproject.toml to Ultimaker B.V. under LGPL-3+ ◂
  • Files: debian/copyright:5-7, pyproject.toml, debian/patches/0001-add-pyproject-toml.patch
  • Basis: checked, in the package or with a reference tool
  • Evidence: Files: * / Copyright: 2015-2022 Ultimaker B.V. / License: LGPL-3+; the patch starts with --- a/pyproject.toml 1970-01-01 01:00:00.000000000 +0100, and .gitignore:74 lists pyproject.toml, so the file is not in the upstream tarball.
  • Problem: copyright-format 6.3 requires each file's actual copyright holders and licence. The top-level pyproject.toml exists only because of the Debian patch (upstream generates it with its Conan toolchain and does not ship it), so neither Ultimaker's copyright nor LGPL-3+ is an accurate statement for that file; the comment in debian/rules makes clear it is the packager's build wiring.
  • Fix: Add a Files: pyproject.toml stanza (Copyright: 2026 Christoph Berg myon@debian.org, License: BSD-3-clause), or drop the patch and generate the file from debian/rules, in which case it is covered by debian/*.
minor packaging 2. Patch 0001-add-pyproject-toml.patch has no DEP-3 header (no Description, Origin or Forwarded) ◂
  • Files: debian/patches/0001-add-pyproject-toml.patch:1, debian/patches/series:1
  • Basis: checked, in the package or with a reference tool
  • Evidence: The file begins directly with --- a/pyproject.toml 1970-01-01 01:00:00.000000000 +0100, with no Description:/Forwarded: fields; .gitignore shows upstream generates this file from its Conan pyprojecttoolchain.
  • Problem: The only patch in the package adds a build file, and neither its purpose nor whether it was offered upstream is recorded. DEP-3 headers are the established way to make a patch self-documenting for the next maintainer and for the upstream release that will make it unnecessary.
  • Fix: Add a DEP-3 header with a one-line Description and a Forwarded field (forwarding the file to Ultimaker, since upstream's Conan build generates the same content), so the patch can be dropped when 5.4.0 ships with it.
Verified ◂
  • Read all of debian/ except debian/watch (out of scope): changelog, control, copyright, rules, source/format, gbp.conf, salsa-ci.yml, patches/series, patches/0001-add-pyproject-toml.patch, tests/control, tests/import.
  • Upstream inventory (21 files, .pc/ excluded): LICENSE, README.md, CMakeLists.txt, conanfile.py, .clang-format, .clang-tidy, .gitignore, .github/workflows/{conan-package.yml,process-pull-request.yml,requirements-conan-package.txt}, include/pyArcus/PythonMessage.h, python/{pyArcus,Types,SocketListener,PythonMessage,Error}.sip, src/PythonMessage.cpp, test_package/{conanfile.py,test.proto,test.py}, pyproject.toml.
  • Every C/C++/sip file carries // Copyright (c) 2022 Ultimaker B.V. and // pyArcus is released under the terms of the LGPLv3 or higher.; README and conanfile.py name Ultimaker and LGPL-3 (conanfile license = "LGPL-3.0"); the remaining files carry no separate notices and are covered by the top-level LICENSE, which is the LGPL-3 text.
  • Prescan holder: the flagged 'Ultimaker B.V. pyArcus is released' matches the header of include/pyArcus/PythonMessage.h, src/PythonMessage.cpp and the five python/*.sip files, and Files: * names Ultimaker B.V., so no holder is missing from debian/copyright.
  • No non-free wording in the tree (no non-commercial/ND clauses, no 'Good, not Evil'), no file without a licence path, and no built binaries, minified files, archives or PDFs: the SIP module's C++ is generated at build time from the shipped python/*.sip, so the preferred form for modification is present.
  • test_package/{conanfile.py,test.proto,test.py} are upstream's Conan test recipe and data, not built or installed by the Debian package; .github/workflows/* is upstream CI configuration referencing external actions; no vendored third-party code is embedded.
  • pyproject.toml is not upstream content: .gitignore:74 lists pyproject.toml, and debian/patches/0001-add-pyproject-toml.patch creates it.
  • Build wiring checked against /usr/share/dh-python/dhpython/build/plugin_pyproject.py: the pyproject build system is part of dh-python and needs python3-build, python3-installer and the sipbuild backend; Build-Depends has the first two and python3-sipbuild (which Depends python3-setuptools), so the absent python3-setuptools/python3-wheel entries are not a fault, and pybuild runs python3 -m build --no-isolation --wheel.
  • Autopkgtest: tests/import is Restrictions: superficial, Depends python3-all, and imports pyArcus with every py3versions -s interpreter, consistent with building for python3-all-dev.
  • Standards-Version 4.7.4: its first two components match the reviewing system's Policy 4.7.x, so it is not an issue.
  • python3-arcus is currently also built by libarcus 5.0.0-6 (apt-cache); pyarcus's python3-arcus 5.3.0-1 is the higher version, so the upgrade path is ordinary, but libarcus must stop building that binary to avoid a later conflict.
  • uscan found the packaged version as the newest upstream release (upstream 5.3.0, packaged 5.3.0).
  • Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (LGPL-3).
Not confirmed ◂
  • libarcus-dev (>= 5.3.0) in Build-Depends: apt-cache shows only 5.0.0-6+b4 in unstable/experimental, so the versioned dependency cannot be satisfied from the package lists; if libarcus 5.3.0 is waiting in NEW this is only sequencing, which I could not see, and a build would otherwise fail dependency resolution.
  • Nothing was built or run: sip code generation, the build and the autopkgtest could not be exercised in this read-only review.
Proposed changes ◂

None.
