 Creative Commons Attribution 4.0 International Public License
 .
 By exercising the Licensed Rights (defined below), You accept and agree
 to be bound by the terms and conditions of this Creative Commons
 Attribution 4.0 International Public License ("Public License"). To the
 extent this Public License may be interpreted as a contract, You are
 granted the Licensed Rights in consideration of Your acceptance of
 these terms and conditions, and the Licensor grants You such rights in
 consideration of benefits the Licensor receives from making the
 Licensed Material available under these terms and conditions.
 .
 Section 1 -- Definitions.
 .
  a. Adapted Material means material subject to Copyright and Similar
     Rights that is derived from or based upon the Licensed Material
     and in which the Licensed Material is translated, altered,
     arranged, transformed, or otherwise modified in a manner requiring
     permission under the Copyright and Similar Rights held by the
     Licensor. For purposes of this Public License, where the Licensed
     Material is a musical work, performance, or sound recording,
     Adapted Material is always produced where the Licensed Material is
     synched in timed relation with a moving image.
 .
  b. Adapter's License means the license You apply to Your Copyright
     and Similar Rights in Your contributions to Adapted Material in
     accordance with the terms and conditions of this Public License.
 .
  c. Copyright and Similar Rights means copyright and/or similar rights
     closely related to copyright including, without limitation,
     performance, broadcast, sound recording, and Sui Generis Database
     Rights, without regard to how the rights are labeled or
     categorized. For purposes of this Public License, the rights
     specified in Section 2(b)(1)-(2) are not Copyright and Similar
     Rights.
 .
  d. Effective Technological Measures means those measures that, in the
     absence of proper authority, may not be circumvented under laws
     fulfilling obligations under Article 11 of the WIPO Copyright
     Treaty adopted on December 20, 1996, and/or similar international
     agreements.
 .
  e. Exceptions and Limitations means fair use, fair dealing, and/or
     any other exception or limitation to Copyright and Similar Rights
     that applies to Your use of the Licensed Material.
 .
  f. Licensed Material means the artistic or literary work, database,
     or other material to which the Licensor applied this Public
     License.
 .
  g. Licensed Rights means the rights granted to You subject to the
     terms and conditions of this Public License, which are limited to
     all Copyright and Similar Rights that apply to Your use of the
     Licensed Material and that the Licensor has authority to license.
 .
  h. Licensor means the individual(s) or entity(ies) granting rights
     under this Public License.
 .
  i. Share means to provide material to the public by any means or
     process that requires permission under the Licensed Rights, such
     as reproduction, public display, public performance, distribution,
     dissemination, communication, or importation, and to make material
     available to the public including in ways that members of the
     public may access the material from a place and at a time
     individually chosen by them.
 .
  j. Sui Generis Database Rights means rights other than copyright
     resulting from Directive 96/9/EC of the European Parliament and of
     the Council of 11 March 1996 on the legal protection of databases,
     as amended and/or succeeded, as well as other essentially
     equivalent rights anywhere in the world.
 .
  k. You means the individual or entity exercising the Licensed Rights
     under this Public License. Your has a corresponding meaning.
 .
 Section 2 -- Scope.
 .
  a. License grant.
 .
       1. Subject to the terms and conditions of this Public License,
          the Licensor hereby grants You a worldwide, royalty-free,
          non-sublicensable, non-exclusive, irrevocable license to
          exercise the Licensed Rights in the Licensed Material to:
 .
            a. reproduce and Share the Licensed Material, in whole or
               in part; and
 .
            b. produce, reproduce, and Share Adapted Material.
 .
       2. Exceptions and Limitations. For the avoidance of doubt, where
          Exceptions and Limitations apply to Your use, this Public
          License does not apply, and You do not need to comply with
          its terms and conditions.
 .
       3. Term. The term of this Public License is specified in Section
          6(a).
 .
       4. Media and formats; technical modifications allowed. The
          Licensor authorizes You to exercise the Licensed Rights in
          all media and formats whether now known or hereafter created,
          and to make technical modifications necessary to do so. The
          Licensor waives and/or agrees not to assert any right or
          authority to forbid You from making technical modifications
          necessary to exercise the Licensed Rights, including
          technical modifications necessary to circumvent Effective
          Technological Measures. For purposes of this Public License,
          simply making modifications authorized by this Section 2(a)
          (4) never produces Adapted Material.
 .
       5. Downstream recipients.
 .
            a. Offer from the Licensor -- Licensed Material. Every
               recipient of the Licensed Material automatically
               receives an offer from the Licensor to exercise the
               Licensed Rights under the terms and conditions of this
               Public License.
 .
            b. No downstream restrictions. You may not offer or impose
               any additional or different terms or conditions on, or
               apply any Effective Technological Measures to, the
               Licensed Material if doing so restricts exercise of the
               Licensed Rights by any recipient of the Licensed
               Material.
 .
       6. No endorsement. Nothing in this Public License constitutes or
          may be construed as permission to assert or imply that You
          are, or that Your use of the Licensed Material is, connected
          with, or sponsored, endorsed, or granted official status by,
          the Licensor or others designated to receive attribution as
          provided in Section 3(a)(1)(A)(i).
 .
  b. Other rights.
 .
       1. Moral rights, such as the right of integrity, are not
          licensed under this Public License, nor are publicity,
          privacy, and/or other similar personality rights; however, to
          the extent possible, the Licensor waives and/or agrees not to
          assert any such rights held by the Licensor to the limited
          extent necessary to allow You to exercise the Licensed
          Rights, but not otherwise.
 .
       2. Patent and trademark rights are not licensed under this
          Public License.
 .
       3. To the extent possible, the Licensor waives any right to
          collect royalties from You for the exercise of the Licensed
          Rights, whether directly or through a collecting society
          under any voluntary or waivable statutory or compulsory
          licensing scheme. In all other cases the Licensor expressly
          reserves any right to collect such royalties.
 .
 Section 3 -- License Conditions.
 .
 Your exercise of the Licensed Rights is expressly made subject to the
 following conditions.
 .
  a. Attribution.
 .
       1. If You Share the Licensed Material (including in modified
          form), You must:
 .
            a. retain the following if it is supplied by the Licensor
               with the Licensed Material:
 .
                 i. identification of the creator(s) of the Licensed
                    Material and any others designated to receive
                    attribution, in any reasonable manner requested by
                    the Licensor (including by pseudonym if
                    designated);
 .
                ii. a copyright notice;
 .
               iii. a notice that refers to this Public License;
 .
                iv. a notice that refers to the disclaimer of
                    warranties;
 .
                 v. a URI or hyperlink to the Licensed Material to the
                    extent reasonably practicable;
 .
            b. indicate if You modified the Licensed Material and
               retain an indication of any previous modifications; and
 .
            c. indicate the Licensed Material is licensed under this
               Public License, and include the text of, or the URI or
               hyperlink to, this Public License.
 .
       2. You may satisfy the conditions in Section 3(a)(1) in any
          reasonable manner based on the medium, means, and context in
          which You Share the Licensed Material. For example, it may be
          reasonable to satisfy the conditions by providing a URI or
          hyperlink to a resource that includes the required
          information.
 .
       3. If requested by the Licensor, You must remove any of the
          information required by Section 3(a)(1)(A) to the extent
          reasonably practicable.
 .
       4. If You Share Adapted Material You produce, the Adapter's
          License You apply must not prevent recipients of the Adapted
          Material from complying with this Public License.
 .
 Section 4 -- Sui Generis Database Rights.
 .
 Where the Licensed Rights include Sui Generis Database Rights that
 apply to Your use of the Licensed Material:
 .
  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
     to extract, reuse, reproduce, and Share all or a substantial
     portion of the contents of the database;
 .
  b. if You include all or a substantial portion of the database
     contents in a database in which You have Sui Generis Database
     Rights, then the database in which You have Sui Generis Database
     Rights (but not its individual contents) is Adapted Material; and
 .
  c. You must comply with the conditions in Section 3(a) if You Share
     all or a substantial portion of the contents of the database.
 .
 For the avoidance of doubt, this Section 4 supplements and does not
 replace Your obligations under this Public License where the Licensed
 Rights include other Copyright and Similar Rights.
 .
 Section 5 -- Disclaimer of Warranties and Limitation of Liability.
 .
  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
 .
  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
 .
  c. The disclaimer of warranties and limitation of liability provided
     above shall be interpreted in a manner that, to the extent
     possible, most closely approximates an absolute disclaimer and
     waiver of all liability.
 .
 Section 6 -- Term and Termination.
 .
  a. This Public License applies for the term of the Copyright and
     Similar Rights licensed here. However, if You fail to comply with
     this Public License, then Your rights under this Public License
     terminate automatically.
 .
  b. Where Your right to use the Licensed Material has terminated under
     Section 6(a), it reinstates:
 .
       1. automatically as of the date the violation is cured, provided
          it is cured within 30 days of Your discovery of the
          violation; or
 .
       2. upon express reinstatement by the Licensor.
 .
     For the avoidance of doubt, this Section 6(b) does not affect any
     right the Licensor may have to seek remedies for Your violations
     of this Public License.
 .
  c. For the avoidance of doubt, the Licensor may also offer the
     Licensed Material under separate terms or conditions or stop
     distributing the Licensed Material at any time; however, doing so
     will not terminate this Public License.
 .
  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
     License.
 .
 Section 7 -- Other Terms and Conditions.
 .
  a. The Licensor shall not be bound by any additional or different
     terms or conditions communicated by You unless expressly agreed.
 .
  b. Any arrangements, understandings, or agreements regarding the
     Licensed Material not stated herein are separate from and
     independent of the terms and conditions of this Public License.
 .
 Section 8 -- Interpretation.
 .
  a. For the avoidance of doubt, this Public License does not, and
     shall not be interpreted to, reduce, limit, restrict, or impose
     conditions on any use of the Licensed Material that could lawfully
     be made without permission under this Public License.
 .
  b. To the extent possible, if any provision of this Public License is
     deemed unenforceable, it shall be automatically reformed to the
     minimum extent necessary to make it enforceable. If the provision
     cannot be reformed, it shall be severed from this Public License
     without affecting the enforceability of the remaining terms and
     conditions.
 .
  c. No term or condition of this Public License will be waived and no
     failure to comply consented to unless expressly agreed to by the
     Licensor.
 .
  d. Nothing in this Public License constitutes or may be interpreted
     as a limitation upon, or waiver of, any privileges and immunities
     that apply to the Licensor or You, including from the legal
     processes of any jurisdiction or authority.

DFSG Assistant LLM REVIEW 1 blocker, 1 important, 1 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 zam-plugins version 4.5+ds-2

Summary

  • Licensing is DFSG-compliant and debian/copyright is accurate: No
  • Packaging is of good quality: Yes
  • Issues: 1 blocker, 1 important, 1 minor
  • debian/watch: version 5
  • debian/copyright: machine-readable
  • Scan before the review: nothing found

Licensing

Most of the tree is free and correctly recorded: GPL-2+ for Damien Zammit's plugins (the catch-all plus explicit stanzas for Robin Gareus, Jeffrey Welty, Stephen Moshier/Cephes, Steve Folta/Anders Dahnielson), GPL-2 for the imported Wavechild670 files, ISC for widgets/ZamWidgets.hpp, and CC-BY for the 23 SVG artworks, with the licence texts present or pointing at /usr/share/common-licenses. Two vendored fonts (plugins/*/artwork/Allstar4.ttf and Amperzand.ttf) carry only a DaFont "100% Free for personal and commercial usage" statement, which grants no right to redistribute or modify them and is not a licence at all, so the source package is not fully DFSG-free. debian/copyright is also inaccurate for plugins/ZamChild670/: its broad plugins/ZamChild670/* stanza overrides the GPL-2+/Damien Zammit catch-all for Damien's own GPL-2+ plugin code and artwork in that directory.

Packaging

The packaging is in good shape: debhelper compat 14 with dh $@, format 3.0 (quilt), Standards-Version 4.7.4 against Policy 4.7.4.1, the 4.2 package's files split into per-format packages with correct Breaks/Replaces on zam-plugins (<< 4.5+ds-1), build and autopkgtest dependencies that exist in the archive, and a smoke test that exercises the installed plugins. The only real defect is that all long descriptions were updated in this upload but still omit the shipped ZamNoise and ZamEcho plugins.

Issues

1. [blocker] [licensing] Allstar4.ttf and Amperzand.ttf are shipped under a DaFont usage statement that grants neither redistribution nor modification

  • Files: debian/copyright:40-51, plugins/*/artwork/Allstar4.ttf, plugins/*/artwork/Amperzand.ttf
  • Basis: checked, in the package or with a reference tool
  • Evidence: Copyright: 2008 Davyboy723 / License: Permissive / The author Davyboy723 released this font on DaFont as "100% Free" for personal and commercial usage. (and the same for 2010 AJ Paglia / Amperzand.ttf).
  • Problem: The recorded text describes how the font was published, not a licence: it permits use, and says nothing about distributing the file or distributing modified versions. DFSG 1 (free redistribution) and DFSG 3 (derived works, same terms) are therefore not met, and "Permissive" is a made-up short name for text that is not a licence; the fonts cannot be in main as they stand. The files are cargo, not build input: the GUI artwork that the plugins compile is pre-rendered PNG in the same directories, the SVGs only name the fonts in font-family attributes, and no debian/*.install file ships the .ttf.
  • Fix: Remove both fonts from the source package (add plugins/*/artwork/*.ttf to Files-Excluded and repack, or replace them with a font under an explicit free licence) and drop the two stanzas; if upstream supplies a real licence grant instead, reproduce its full text and holder under a proper short name.

2. [important] [licensing] Files stanza plugins/ZamChild670/* attributes Damien Zammit's GPL-2+ plugin code and artwork to Peter Raffensperger under GPL-2

  • Files: debian/copyright:20-23, plugins/ZamChild670/ZamChild670Plugin.cpp:3, plugins/ZamChild670/ZamChild670UI.cpp:3, plugins/ZamChild670/DistrhoPluginInfo.h:3, plugins/ZamChild670/artwork/knob.png, plugins/ZamChild670/artwork/zamchild670.png
  • Basis: checked, in the package or with a reference tool
  • Evidence: Stanza: Files: / plugins/ZamChild670/* / Copyright: 2012 Peter Raffensperger / License: GPL-2. File headers: * Copyright (C) 2015 Damien Zammit <damien@zamaudio.com> ... either version 2 of the License, or (at your option) any later version (ZamChild670Plugin.cpp, ZamChild670UI.cpp, DistrhoPluginInfo.h 2014 Damien Zammit).
  • Problem: The stanza's * matches every file below the directory, so it is the last matching stanza for Damien's ZamChild670* sources and for artwork/knob.png and artwork/zamchild670.png, overriding the Files: * GPL-2+/Damien Zammit stanza and omitting their real holder (copyright-format 6.9, last matching stanza wins). Only artwork/zamchild670.svg escapes, because the later CC-BY stanza lists it explicitly. debian/copyright therefore misstates both the holder and the licence (GPL-2 instead of GPL-2+) of files whose own headers say otherwise.
  • Fix: Narrow the stanza to the imported Wavechild670 files (wavechild670., tubemodel., sidechainamplifier., variablemuamplifier., wdfcircuits.*, generatedwdfutilities.h and glue.h), and let the rest of plugins/ZamChild670/ fall under Files: * (or give it its own Damien Zammit / GPL-2+ stanza, with the artwork at its actual licence).

3. [minor] [packaging] Long descriptions omit the shipped ZamNoise and ZamEcho plugins

  • Files: debian/control:47-84, debian/control:280-312, Makefile:10, plugins/ZamNoise/Makefile:39-45, plugins/ZamEcho/Makefile:23-29
  • Basis: checked, in the package or with a reference tool
  • Evidence: PLUGINS=ZamComp ... ZamPhono ZamVerb ZamGrains ZamNoise ZamEcho (Makefile:10); both plugin Makefiles add TARGETS += lv2_sep, ladspa, vst2, vst3, clap, jack. Every description lists 17 plugins from * ZamAutoSat to * ZamGrains and neither ZamNoise nor ZamEcho appears anywhere in debian/control (grep ZamNoise|ZamEcho in it: no match).
  • Problem: Two of the plugins that are built and shipped in every plugin package (ZamEcho is new in 4.5, ZamNoise in 4.3) are undocumented, so users cannot discover them from the package descriptions, and this upload's changelog claims the plugin lists were fixed.
  • Fix: Add * ZamNoise and * ZamEcho (with their one-line descriptions) to the long description of each of the six plugin-bearing packages.

Verified

  • The pre-scan's author check is confirmed: every copyright holder found in the tree (Damien Zammit, Robin Gareus, Jeffrey J. Welty, Stephen L. Moshier, Peter Raffensperger, Steve Folta, Anders Dahnielson, Filipe Coelho, Davyboy723, AJ Paglia, and the Debian maintainers) is named in debian/copyright; I re-read the headers of plugins/ZamVerb and plugins/ZamHeadX2/convolution., plugins/ZamNoise/Denoise., bessel.inc, plugins/ZamChild670/wavechild670.h, tubemodel.h, sidechainamplifier.h, wdfcircuits.h, plugins/ZamSFZ/libsfz/sfz.h, widgets/ZamWidgets.hpp and the ZamComp/ZamTube/ZamPiano/ZamSynth/ZamEcho plugin sources.
  • All 23 SVGs under plugins/*/artwork/ (ZaMaximX2, ZaMultiComp, ZaMultiCompX2, ZamAutoSat, ZamChild670, ZamComp, ZamCompX2, ZamDelay, ZamEcho, ZamDynamicEQ, ZamEQ2, ZamGEQ31, ZamGate, ZamGateX2, ZamGrains, ZamHeadX2, ZamNoise, ZamPhono, ZamPiano, ZamSFZ, ZamSynth, ZamTube, ZamVerb) are listed in the CC-BY stanza; their metadata only says License: creative commons attribution.
  • The auto-generated artwork sources (*Artwork.cpp, e.g. plugins/ZamChild670/ZamChild670Artwork.cpp /* (Auto-generated binary data file). */) have their inputs in the same artwork/ directories as PNG files, and are the generated form of shipped sources, not built packages.
  • The six files over 4 MiB that the scan could only partly read are the ZamVerb impulse responses plugins/ZamVerb/hallA_4.inc, hallB_4.inc, plate_4.inc, roomA_4.inc, roomB_4.inc and studioB_4.inc: plain comma-separated float arrays with no notice, covered by the Files: * GPL-2+ stanza.
  • plugins/ZamHeadX2/l1-l50 and r1-r50 are likewise plain numeric HRTF arrays (about 100 KB each) with no licence or copyright notice, covered by Files: *.
  • The .ttf files are not installed: the debian/*.install files ship only usr/lib/{lv2,ladspa,vst,vst3,clap}/ and usr/bin/, and no generated artwork source references them (grep for Allstar4/Amperzand finds only the SVG font-family attributes).
  • dpf/ is an empty directory in the tarball; DPF is copied from dpf-source at build time (debian/rules execute_before_dh_auto_configure) and removed again in clean, and lib/ (removed by Files-Excluded) is absent, so no unlicensed or non-free dpf/lib copies remain.
  • Licence texts: GPL-2 and GPL-2+ point at /usr/share/common-licenses/GPL-2, and Expat, ISC, Cephes and CC-BY-4.0 texts are included in full in debian/copyright; the expat/ISC texts match the file headers.
  • Packaging checks: compat 14 with dh $@; format 3.0 (quilt) with two DEP-3 patches that are applied and relevant; Standards-Version 4.7.4 against Policy 4.7.4.1; the split packages carry Breaks+Replaces on zam-plugins (<< 4.5+ds-1) for the files the old single package owned, the meta package is Architecture: all; lv2file, lilv-utils, ladspa-sdk and ffmpeg exist in the archive as tests/control and the .dsc Testsuite-Triggers say; libfftw3-dev and libx11-dev come with libzita-convolver-dev and libgl-dev.
  • The changelog is sane (unstable, 4.5+ds-2, valid bug closures) and debian/copyright already starts with the current Format: line, so no replacement copyright file is proposed.
  • uscan found the packaged version as the newest upstream release (upstream 4.5, packaged 4.5+ds).
  • Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (GPL-2).

Not confirmed

  • The actual DaFont terms behind the two fonts: I could only read debian/copyright's description of them, not the site, so my finding rests on the recorded text granting use only.
  • The provenance of the ZamVerb impulse responses (.inc) and the ZamHeadX2 HRTF responses (l/r*): no notice or README says where they came from, so I could not confirm that they are Damien Zammit's own measurements as the Files: * stanza asserts; a restricted source dataset would be a DFSG problem.
  • The version of CC BY the SVGs are under: their RDF metadata carries no cc:license or version, so the CC-BY-4.0 text in debian/copyright cannot be confirmed from the source.
  • debian/gbp/postclone.sh and debian/README.source look like IOhannes m zmolnig's text (README.source is signed by him) but carry no copyright notice, and the debian/* stanza names only other maintainers; I did not report this as a missing holder.
  • I did not check the executable bit or the runtime behaviour of debian/tests/smoke, and I could not inspect the .ttf binaries (fonts) or the PNG files.
  • debian/watch looks at github.com/zamaudio/@package@, but the Source field of debian/copyright names github.com/zamaudio/zam-plugins. Whether these are the same upstream was not checked.
  • debian/watch looks at github.com/zamaudio/@package@, but Repository in debian/upstream/metadata names github.com/zamaudio/zam-plugins. Whether these are the same upstream was not checked.

Proposed changes

None.

Uploader's response to the LLM review

i know, i cant find the licenses of those font only that the author called them 100% free, but whatever, this can not be easily fixed. If i replace the fonts the application may look different or do not fit with the new fonts... so maybe upstream can fix that later. but what should i do, honestly? surely best would be to replace them with fonts from debian archive.

so i can upload the package -3 and fix 2. but if it still complains about the fonts then im lost... i already spent some days on this package.
I opened a new upstream issue about this: https://github.com/zamaudio/zam-plugins/issues/111

Please reply if this is really a hard blocker and its really need to replace those fonts, and that the package can not be like that in debian main.

Upstream closed my bug as completed, pointing out these are free licenses ^^ https://github.com/zamaudio/zam-plugins/commit/7ebdb5ac6b89a1a27637617701965b86d453f2e8
