Changelog
sagemath (10.10-4) unstable; urgency=medium
.
* d/rules: Run the tests without --long on riscv64, as the buildds are
slow there.
* Replace the generated d/control by a static one.
* d/control: Drop dependencies of python3-sage that ${python3:Depends}
already provides, and pari-doc, which is also in Recommends.
* New package sagemath-dev, which depends on what is needed to compile
Cython and Fortran code in Sage. python3-sage now only recommends it
instead of depending on all -dev packages and cython3. Add
d/py3dist-overrides to keep dh_python3 from adding cython3 to
${python3:Depends}. (Closes: #1058014)
* d/tests: Add the autopkgtest without-dev, which checks that Sage's
backends work without sagemath-dev installed.
* d/control: Drop dependencies on programs Sage never runs, and on -dev
packages that are not used at all. Move r-base-dev to Suggests.
* d/depcheck.py: Check that the runtime dependencies are in Build-Depends
instead of comparing with upstream's lists for building Sage from source.
* d/control: Mark Build-Depends only needed for the tests with <!nocheck>,
or with <!nocheck> <!nodoc> if the documentation build may need them.
* d/control: Move the Build-Depends only needed to build the documentation
to Build-Depends-Indep, so that architecture-specific builds don't
install them.
* d/control: Drop the debhelper constraint, debhelper-compat implies it.
* Drop d/sage_conf.py, which Sage no longer reads. Set the Debian paths it
contained that meson doesn't configure and Sage doesn't find by itself
(SAGE_DOC, MATHJAX_DIR, PPLPY_DOCS, RUBIKS_BINS_PREFIX) in
d/patches/d1-env-paths.patch instead.
* Depend on maxima-sage >= 5.50.0-4.
* Enable dh_sphinxdoc via dh-sequence-sphinxdoc <!nodoc> in
Build-Depends-Indep instead of --with, so that builds with the nodoc
profile don't need sphinx.
* Fix lintian warnings:
- d/rules: Also remove the executable bit from the dokchitser testall
script, whose shebang is removed.
- Drop d/source/lintian-overrides, none of its overrides are used.
* d/control: Build-Depend on python3-numpy, whose numpy.pxd is cimported..dsc

Comment:
The file src/doc/en/reference/history_and_license/index.rst contains the incorrect
statement "All documentation is released under the GNU Free Documentation License."
This is in contradiction to several statements placing documentation under CC-BY-SA-3.0,
e.g. in src/doc/en/reference/index.rst.
This oversight was fixed in the upstream git repo, the reference to the GFDL was removed.

License
.
THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
.
BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO
BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY BE
CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS CONTAINED
HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.
.
1. Definitions
"Adaptation" means a work based upon the Work, or upon the Work and
other pre-existing works, such as a translation, adaptation, derivative
work, arrangement of music or other alterations of a literary or
artistic work, or phonogram or performance and includes cinematographic
adaptations or any other form in which the Work may be recast,
transformed, or adapted including in any form recognizably derived from
the original, except that a work that constitutes a Collection will not
be considered an Adaptation for the purpose of this License. For the
avoidance of doubt, where the Work is a musical work, performance or
phonogram, the synchronization of the Work in timed-relation with a
moving image ("synching") will be considered an Adaptation for the
purpose of this License.
"Collection" means a collection of literary or artistic works, such as
encyclopedias and anthologies, or performances, phonograms or
broadcasts, or other works or subject matter other than works listed in
Section 1(f) below, which, by reason of the selection and arrangement of
their contents, constitute intellectual creations, in which the Work is
included in its entirety in unmodified form along with one or more other
contributions, each constituting separate and independent works in
themselves, which together are assembled into a collective whole. A work
that constitutes a Collection will not be considered an Adaptation (as
defined below) for the purposes of this License.
"Creative Commons Compatible License" means a license that is listed at
http://creativecommons.org/compatiblelicenses that has been approved by
Creative Commons as being essentially equivalent to this License,
including, at a minimum, because that license: (i) contains terms that
have the same purpose, meaning and effect as the License Elements of
this License; and, (ii) explicitly permits the relicensing of
adaptations of works made available under that license under this
License or a Creative Commons jurisdiction license with the same License
Elements as this License.
"Distribute" means to make available to the public the original and
copies of the Work or Adaptation, as appropriate, through sale or other
transfer of ownership.
"License Elements" means the following high-level license attributes as
selected by Licensor and indicated in the title of this License:
Attribution, ShareAlike.
"Licensor" means the individual, individuals, entity or entities that
offer(s) the Work under the terms of this License.
"Original Author" means, in the case of a literary or artistic work, the
individual, individuals, entity or entities who created the Work or if
no individual or entity can be identified, the publisher; and in
addition (i) in the case of a performance the actors, singers,
musicians, dancers, and other persons who act, sing, deliver, declaim,
play in, interpret or otherwise perform literary or artistic works or
expressions of folklore; (ii) in the case of a phonogram the producer
being the person or legal entity who first fixes the sounds of a
performance or other sounds; and, (iii) in the case of broadcasts, the
organization that transmits the broadcast.
"Work" means the literary and/or artistic work offered under the terms
of this License including without limitation any production in the
literary, scientific and artistic domain, whatever may be the mode or
form of its expression including digital form, such as a book, pamphlet
and other writing; a lecture, address, sermon or other work of the same
nature; a dramatic or dramatico-musical work; a choreographic work or
entertainment in dumb show; a musical composition with or without words;
a cinematographic work to which are assimilated works expressed by a
process analogous to cinematography; a work of drawing, painting,
architecture, sculpture, engraving or lithography; a photographic work
to which are assimilated works expressed by a process analogous to
photography; a work of applied art; an illustration, map, plan, sketch
or three-dimensional work relative to geography, topography,
architecture or science; a performance; a broadcast; a phonogram; a
compilation of data to the extent it is protected as a copyrightable
work; or a work performed by a variety or circus performer to the extent
it is not otherwise considered a literary or artistic work.
"You" means an individual or entity exercising rights under this License
who has not previously violated the terms of this License with respect
to the Work, or who has received express permission from the Licensor to
exercise rights under this License despite a previous violation.
"Publicly Perform" means to perform public recitations of the Work and
to communicate to the public those public recitations, by any means or
process, including by wire or wireless means or public digital
performances; to make available to the public Works in such a way that
members of the public may access these Works from a place and at a place
individually chosen by them; to perform the Work to the public by any
means or process and the communication to the public of the performances
of the Work, including by public digital performance; to broadcast and
rebroadcast the Work by any means including signs, sounds or images.
"Reproduce" means to make copies of the Work by any means including
without limitation by sound or visual recordings and the right of
fixation and reproducing fixations of the Work, including storage of a
protected performance or phonogram in digital form or other electronic
medium.
.
2. Fair Dealing Rights. Nothing in this License is intended to reduce,
limit, or restrict any uses free from copyright or rights arising from
limitations or exceptions that are provided for in connection with the
copyright protection under copyright law or other applicable laws.
.
3. License Grant. Subject to the terms and conditions of this License,
Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
perpetual (for the duration of the applicable copyright) license to
exercise the rights in the Work as stated below:
.
to Reproduce the Work, to incorporate the Work into one or more
Collections, and to Reproduce the Work as incorporated in the
Collections;
to create and Reproduce Adaptations provided that any such Adaptation,
including any translation in any medium, takes reasonable steps to
clearly label, demarcate or otherwise identify that changes were made to
the original Work. For example, a translation could be marked "The
original work was translated from English to Spanish," or a modification
could indicate "The original work has been modified.";
to Distribute and Publicly Perform the Work including as incorporated in
Collections; and,
to Distribute and Publicly Perform Adaptations.
.
For the avoidance of doubt:
Non-waivable Compulsory License Schemes. In those jurisdictions in
which the right to collect royalties through any statutory or
compulsory licensing scheme cannot be waived, the Licensor reserves
the exclusive right to collect such royalties for any exercise by
You of the rights granted under this License;
Waivable Compulsory License Schemes. In those jurisdictions in which
the right to collect royalties through any statutory or compulsory
licensing scheme can be waived, the Licensor waives the exclusive
right to collect such royalties for any exercise by You of the
rights granted under this License; and,
Voluntary License Schemes. The Licensor waives the right to collect
royalties, whether individually or, in the event that the Licensor
is a member of a collecting society that administers voluntary
licensing schemes, via that society, from any exercise by You of the
rights granted under this License.
.
The above rights may be exercised in all media and formats whether now
known or hereafter devised. The above rights include the right to make such
modifications as are technically necessary to exercise the rights in other
media and formats. Subject to Section 8(f), all rights not expressly
granted by Licensor are hereby reserved.
.
4. Restrictions. The license granted in Section 3 above is expressly made
subject to and limited by the following restrictions:
.
You may Distribute or Publicly Perform the Work only under the terms of
this License. You must include a copy of, or the Uniform Resource
Identifier (URI) for, this License with every copy of the Work You
Distribute or Publicly Perform. You may not offer or impose any terms on
the Work that restrict the terms of this License or the ability of the
recipient of the Work to exercise the rights granted to that recipient
under the terms of the License. You may not sublicense the Work. You
must keep intact all notices that refer to this License and to the
disclaimer of warranties with every copy of the Work You Distribute or
Publicly Perform. When You Distribute or Publicly Perform the Work, You
may not impose any effective technological measures on the Work that
restrict the ability of a recipient of the Work from You to exercise the
rights granted to that recipient under the terms of the License. This
Section 4(a) applies to the Work as incorporated in a Collection, but
this does not require the Collection apart from the Work itself to be
made subject to the terms of this License. If You create a Collection,
upon notice from any Licensor You must, to the extent practicable,
remove from the Collection any credit as required by Section 4(c), as
requested. If You create an Adaptation, upon notice from any Licensor
You must, to the extent practicable, remove from the Adaptation any
credit as required by Section 4(c), as requested.
You may Distribute or Publicly Perform an Adaptation only under the
terms of: (i) this License; (ii) a later version of this License with
the same License Elements as this License; (iii) a Creative Commons
jurisdiction license (either this or a later license version) that
contains the same License Elements as this License (e.g.,
Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible
License. If you license the Adaptation under one of the licenses
mentioned in (iv), you must comply with the terms of that license. If
you license the Adaptation under the terms of any of the licenses
mentioned in (i), (ii) or (iii) (the "Applicable License"), you must
comply with the terms of the Applicable License generally and the
following provisions: (I) You must include a copy of, or the URI for,
the Applicable License with every copy of each Adaptation You Distribute
or Publicly Perform; (II) You may not offer or impose any terms on the
Adaptation that restrict the terms of the Applicable License or the
ability of the recipient of the Adaptation to exercise the rights
granted to that recipient under the terms of the Applicable License;
(III) You must keep intact all notices that refer to the Applicable
License and to the disclaimer of warranties with every copy of the Work
as included in the Adaptation You Distribute or Publicly Perform; (IV)
when You Distribute or Publicly Perform the Adaptation, You may not
impose any effective technological measures on the Adaptation that
restrict the ability of a recipient of the Adaptation from You to
exercise the rights granted to that recipient under the terms of the
Applicable License. This Section 4(b) applies to the Adaptation as
incorporated in a Collection, but this does not require the Collection
apart from the Adaptation itself to be made subject to the terms of the
Applicable License.
If You Distribute, or Publicly Perform the Work or any Adaptations or
Collections, You must, unless a request has been made pursuant to
Section 4(a), keep intact all copyright notices for the Work and
provide, reasonable to the medium or means You are utilizing: (i) the
name of the Original Author (or pseudonym, if applicable) if supplied,
and/or if the Original Author and/or Licensor designate another party or
parties (e.g., a sponsor institute, publishing entity, journal) for
attribution ("Attribution Parties") in Licensor's copyright notice,
terms of service or by other reasonable means, the name of such party or
parties; (ii) the title of the Work if supplied; (iii) to the extent
reasonably practicable, the URI, if any, that Licensor specifies to be
associated with the Work, unless such URI does not refer to the
copyright notice or licensing information for the Work; and (iv) ,
consistent with Ssection 3(b), in the case of an Adaptation, a credit
identifying the use of the Work in the Adaptation (e.g., "French
translation of the Work by Original Author," or "Screenplay based on
original Work by Original Author"). The credit required by this Section
4(c) may be implemented in any reasonable manner; provided, however,
that in the case of a Adaptation or Collection, at a minimum such credit
will appear, if a credit for all contributing authors of the Adaptation
or Collection appears, then as part of these credits and in a manner at
least as prominent as the credits for the other contributing authors.
For the avoidance of doubt, You may only use the credit required by this
Section for the purpose of attribution in the manner set out above and,
by exercising Your rights under this License, You may not implicitly or
explicitly assert or imply any connection with, sponsorship or
endorsement by the Original Author, Licensor and/or Attribution Parties,
as appropriate, of You or Your use of the Work, without the separate,
express prior written permission of the Original Author, Licensor and/or
Attribution Parties.
Except as otherwise agreed in writing by the Licensor or as may be
otherwise permitted by applicable law, if You Reproduce, Distribute or
Publicly Perform the Work either by itself or as part of any Adaptations
or Collections, You must not distort, mutilate, modify or take other
derogatory action in relation to the Work which would be prejudicial to
the Original Author's honor or reputation. Licensor agrees that in those
jurisdictions (e.g. Japan), in which any exercise of the right granted
in Section 3(b) of this License (the right to make Adaptations) would be
deemed to be a distortion, mutilation, modification or other derogatory
action prejudicial to the Original Author's honor and reputation, the
Licensor will waive or not assert, as appropriate, this Section, to the
fullest extent permitted by the applicable national law, to enable You
to reasonably exercise Your right under Section 3(b) of this License
(right to make Adaptations) but not otherwise.
.
5. Representations, Warranties and Disclaimer
.
UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT
OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER
OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF
IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
.
6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY
SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING
OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
.
7. Termination
.
This License and the rights granted hereunder will terminate
automatically upon any breach by You of the terms of this License.
Individuals or entities who have received Adaptations or Collections
from You under this License, however, will not have their licenses
terminated provided such individuals or entities remain in full
compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
survive any termination of this License.
Subject to the above terms and conditions, the license granted here is
perpetual (for the duration of the applicable copyright in the Work).
Notwithstanding the above, Licensor reserves the right to release the
Work under different license terms or to stop distributing the Work at
any time; provided, however that any such election will not serve to
withdraw this License (or any other license that has been, or is
required to be, granted under the terms of this License), and this
License will continue in full force and effect unless terminated as
stated above.
.
8. Miscellaneous
.
Each time You Distribute or Publicly Perform the Work or a Collection,
the Licensor offers to the recipient a license to the Work on the same
terms and conditions as the license granted to You under this License.
Each time You Distribute or Publicly Perform an Adaptation, Licensor
offers to the recipient a license to the original Work on the same terms
and conditions as the license granted to You under this License.
If any provision of this License is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this License, and without further action
by the parties to this agreement, such provision shall be reformed to
the minimum extent necessary to make such provision valid and
enforceable.
No term or provision of this License shall be deemed waived and no
breach consented to unless such waiver or consent shall be in writing
and signed by the party to be charged with such waiver or consent.
This License constitutes the entire agreement between the parties with
respect to the Work licensed here. There are no understandings,
agreements or representations with respect to the Work not specified
here. Licensor shall not be bound by any additional provisions that may
appear in any communication from You. This License may not be modified
without the mutual written agreement of the Licensor and You.
The rights granted under, and the subject matter referenced, in this
License were drafted utilizing the terminology of the Berne Convention
for the Protection of Literary and Artistic Works (as amended on
September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and
the Universal Copyright Convention (as revised on July 24, 1971). These
rights and subject matter take effect in the relevant jurisdiction in
which the License terms are sought to be enforced according to the
corresponding provisions of the implementation of those treaty
provisions in the applicable national law. If the standard suite of
rights granted under applicable copyright law includes additional rights
not granted under this License, such additional rights are deemed to be
included in the License; this License is not intended to restrict the
license of any rights under applicable law.
DFSG Assistant LLM REVIEW 2 blocker, 1 important, 3 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 sagemath version 10.10-4
Summary
- Licensing is DFSG-compliant and
debian/copyrightis accurate: No - Packaging is of good quality: No
- Issues: 2 blocker, 1 important, 3 minor
- debian/watch: version 5
- debian/copyright: machine-readable
- Scan before the review: 55 found
Licensing
All licences in the tree are free and mutually compatible, and the non-obvious ones are described correctly (bernmm/distributions BSD-2-clause, lazy_string/function_mangling/ncpus BSD-3-clause, ginac/optional.hpp BSL-1.0, game_theory GPL-3+, docs CC-BY-SA-3.0, implicit_surface LGPL-2.1+/GPL-2+). But debian/copyright is not accurate: its Files: * stanza omits a large number of holders of code installed in python3-sage (the scan found 235; the stanza's list stops in 2016), and it labels several GPL-3+-only files as GPL-2+.
Packaging
The packaging is otherwise careful and modern (compat 13, Rules-Requires-Root: no, hardening, two autopkgtests, DEP-3 patch headers, static debian/control, a -dev metapackage, doc package behind <!nodoc>). One defect stops it: runtime dependencies needed by the documentation build are marked <!nocheck> <!nodoc>, although the manual is built in a nocheck build too, so DEB_BUILD_OPTIONS=nocheck builds fail. Also, a Debian patch makes license() read another package's copyright file.
Issues
blocker licensing 1. Files: * does not name the holders of many modules installed in python3-sage (e.g. Birk Eisermann, André Apitzsch, Cameron Franc and Marc Masdeu, Antoine Leudière) ◂
- Files:
debian/copyright:5-303,src/sage/graphs/weakly_chordal.pyx:28,src/sage/matrix/matrix_double_dense.pyx:48,src/sage/modular/btquotients/btquotient.py:33,src/sage/rings/function_field/drinfeld_modules/action.py:14,src/sage/combinat/designs/covering_array.py:45,src/sage/databases/conway.py:7 - Basis: checked, in the package or with a reference tool
- Evidence: The Files: * stanza opens
Copyright: Copyright (C) 2005-2026 The Sage Development Teamand lists holders whose years stop at 2016, endingLicense: GPL-2+. The files themselves say e.g.# Copyright (c) 2012 Birk Eisermann <eisermbi@fastmail.fm>,# Copyright (C) 2011-2014 André Apitzsch,# Copyright (C) 2011 Cameron Franc and Marc Masdeu,# Copyright (C) 2022 Antoine Leudière <antoine.leudiere@inria.fr>; a grep of debian/copyright for these names (and for Aaron Dwyer, Alexandru Ghitza, Ben Hutz, Barinder Banwait, Davide Lombardo, Jayant Apte's co-authors) finds nothing. The pre-review scan reports 235 holders absent; the ~15 I re-checked are genuinely missing. - Problem: These are library modules, and the .pyx files are compiled into the extensions python3-sage installs, so the GPL requires the notices to be kept in the binary distribution; they ship in a binary package in source and compiled form, and they are not plain text stanzas without a notice. Policy 2.3 therefore wants these holders in debian/copyright. A missing holder for code that is compiled into a shipped binary is a blocker.
- Fix: Add the missing holders to the Files: * stanza (and to any per-directory stanza that overrides it), or generate the list from the copyright headers in the tree so that it stays complete.
blocker licensing 2. Files: * labels GPL-3+-only modules as GPL-2+ ◂
- Files:
debian/copyright:303,src/sage/misc/verbose.py:102,src/sage/combinat/recognizable_series.py:46,src/sage/combinat/regular_sequence.py:84,src/sage/modular/drinfeld_modform/ring.py:26,src/sage/matroids/matroids_plot_helpers.py:69,m4/ppl.m4:10 - Basis: checked, in the package or with a reference tool
- Evidence: The catch-all stanza ends
License: GPL-2+, but these files sayThis program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.No later stanza overrides Files: * for them; m4/ppl.m4, an embedded copy of PPL's AM_PATH_PPL macro, sayseither version 3 of the Licenseas well. - Problem: GPL-2+ offers the recipient version 2, which the authors of these files did not grant; the files are GPL-3+ only (SPDX GPL-3.0-or-later). debian/copyright therefore states a licence broader than the one the files carry, for modules shipped in python3-sage, and Policy 2.3 and copyright-format 6.7 require the License field to match the file's terms.
- Fix: Add a
Files:stanza listing these files (at least src/sage/misc/verbose.py, src/sage/combinat/recognizable_series.py, src/sage/combinat/regular_sequence.py, src/sage/combinat/regular_sequence_bounded.py, src/sage/modular/drinfeld_modform/*, src/sage/matroids/matroids_plot_helpers.py, m4/ppl.m4) withLicense: GPL-3+, or correct the catch-all if GPL-3+ is what the whole tree is meant to be.
important packaging 3. python3-ipython and python3-matplotlib are marked <!nocheck>, but a nocheck build still builds the manual, which imports them ◂
- Files:
debian/control:117,debian/control:133,debian/rules:62-70,src/sage_docbuild/conf.py:23,src/sage_docbuild/conf.py:57-58 - Basis: inferred from what was read, not seen directly
- Evidence: debian/control:
python3-ipython (>= 8.9.0) <!nocheck> <!nodoc>,andpython3-matplotlib (>= 3.7.0) <!nocheck> <!nodoc>,. debian/rules:62-70 builds the manual underifeq (,$(filter nodoc,$(DEB_BUILD_PROFILES)))withninja -C .pybuild/cpython3_$(PY3VER)_sage/meson-build doc-html. src/sage_docbuild/conf.py:23 hasfrom IPython.lib.lexers import IPyLexer, IPythonConsoleLexerat module level, and itsextensionslist has'IPython.sphinxext.ipython_directive'(line 57) and'matplotlib.sphinxext.plot_directive'(line 58). None of the unconditional Build-Depends depends on python3-ipython or python3-matplotlib (furo brings only python3-sphinx; python3-networkx only Recommends matplotlib). - Problem: With DEB_BUILD_OPTIONS=nocheck and no nodoc build profile, dpkg does not install the <!nocheck> dependencies, yet the build still runs the documentation target (dh does not skip override_dh_auto_build-indep under nocheck). Sphinx imports conf.py, whose plain-python IPython import fails, and loads matplotlib's plot extension, so the build fails. Builds with the nocheck profile are release-critical: https://wiki.debian.org/qa.debian.org/FTBFS/nocheck.
- Fix: Take <!nocheck> off the dependencies the documentation build needs and leave only <!nodoc>: at least
python3-ipython <!nodoc>andpython3-matplotlib <!nodoc>, and check the other runtime dependencies that the doc build imports (for example libjs-mathjax, which debian/rules passes as MATHJAX_DIR). Keep <!nocheck> only for what the test suite alone needs.
minor licensing 4. m4/ppl.m4 and two m4/ax_*.m4 files carry holders that debian/copyright does not name ◂
- Files:
m4/ppl.m4:1-5,m4/ax_gcc_option.m4:65,m4/ax_gxx_option.m4:66,debian/copyright:362-376 - Basis: checked, in the package or with a reference tool
- Evidence: m4/ppl.m4:
dnl Copyright (C) 1997 Owen Taylor,dnl Copyright (C) 2001-2010 Roberto Bagnara <bagnara@cs.unipr.it>,dnl Copyright (C) 2010-2016 BUGSENG srl; m4/ax_gcc_option.m4 and m4/ax_gxx_option.m4 addCopyright (C) 2016 Bogdan Drozdowski <bogdandr@op.pl>. The m4/ax_*.m4 stanza (debian/copyright:362-376) names 14 other holders and no ppl.m4 stanza exists, so ppl.m4 falls under Files: *. - Problem: The holders are missing, and m4/ppl.m4's GPL-3+ terms are not stated (see the previous issue). These m4 files are used only at configure time and none is installed in a binary package, so Policy 2.3 does not require their notices in debian/copyright; a complete copyright file should still name them.
- Fix: Add Bogdan Drozdowski to the m4/ax_*.m4 stanza and add a
Files: m4/ppl.m4stanza with Owen Taylor, Roberto Bagnara and BUGSENG srl under GPL-3+.
minor licensing 5. debian/* stanza does not name the authors of debian/patches (Maximiliano Curia, Rogo) ◂
- Files:
debian/copyright:305-307,debian/patches/u2-python-3.15-compat.patch:6,debian/patches/dt-ignore-deprecation-warnings.patch:2,src/sage/cpython/compat.h - Basis: checked, in the package or with a reference tool
- Evidence: The stanza says
Copyright: Copyright (C) 2013-2026 Jerome Benoit, Tobias Hansen, Ximin Luo, Julien Puydt, Felix Salfelder, while most patches carryAuthor: Maximiliano Curia <maxy@debian.org>and dt-ignore-deprecation-warnings.patch carriesAuthor: Rogo <rogo95@proton.me>. u2-python-3.15-compat.patch creates src/sage/cpython/compat.h, which is installed in python3-sage and carries no notice of its own. - Problem: Debian's own contributions to the source package are under the debian/* stanza but their holders are not named. Policy 2.3 does not require these holders for files that only exist in the source package, which is why this is minor; the one patch-created header that is installed has no notice to retain either, so the missing attribution is a completeness defect of debian/copyright rather than a lost notice.
- Fix: Add Maximiliano Curia and Rogo (with their years) to the Copyright field of the debian/* stanza.
minor packaging 6. d1-doc-docs.patch makes license() read /usr/share/doc/sagemath/copyright, which need not exist with python3-sage alone ◂
- Files:
src/sage/misc/copying.py:17,debian/patches/d1-doc-docs.patch - Basis: checked, in the package or with a reference tool
- Evidence: The patched function is
with open("/usr/share/doc/sagemath/copyright") as f:. python3-sage does not depend on sagemath (sagemath depends on python3-sage), so a library-only installation has no /usr/share/doc/sagemath. - Problem: In an installation with python3-sage but without the sagemath metapackage, calling license() raises FileNotFoundError instead of showing the GPL text. The upstream code read SAGE_ROOT/COPYING.txt, which Debian does not install, so a patch is needed, but the path chosen is not guaranteed to exist.
- Fix: Read the copyright file of the package that contains the module (for example /usr/share/doc/python3-sage/copyright), or fall back to /usr/share/common-licenses/GPL-2, and keep a fallback if the chosen path is absent.
Verified ◂
- debian/copyright is machine-readable (Format 1.0, correct URL) with stanzas Files: * (GPL-2+), debian/* (GPL-2+), src/sage/game_theory/* (GPL-3+), src/doc/* (CC-BY-SA-3.0), bernmm and stats/distributions (BSD-2-clause), misc/function_mangling.pyx, misc/lazy_string.pyx and parallel/ncpus.py (BSD-3-clause), plot/plot3d/implicit_surface.pyx (LGPL-2.1+ and GPL-2+), symbolic/ginac/optional.hpp (BSL-1.0) and m4/ax_*.m4 (permissive). Full texts are present for BSD-2-clause, BSD-3-clause, BSL-1.0, CC-BY-SA-3.0 and the permissive licence; the GPL/LGPL stanzas point at /usr/share/common-licenses with the license texts quoted.
- All licences found are DFSG-free and mutually compatible: GPL-2+ and GPL-3+ code combine under GPL-3, the one LGPL-2.1+/GPL-2+ file is compatible, and the BSD/BSL/CC-BY-SA material is in separate files or documents.
- Sampled headers confirm the special stanzas: src/sage/rings/bernmm/bern_modp.cpp ('bernmm is released under a BSD-style license'), src/sage/stats/distributions/dgs_bern.c (BSD-2 with Martin Albrecht), src/sage/misc/lazy_string.pyx ('Copyright (c) 2009 by Armin Ronacher'), src/sage/symbolic/ginac/optional.hpp ('Distributed under the Boost Software License, Version 1.0'), src/sage/game_theory/*.py (GPL-3+, except parser.py which is GPL-2+) and src/sage/plot/plot3d/implicit_surface.pyx (GPL plus Jmol's LGPL-2.1+ marching-cubes tables).
- Prescan archives: build/pkgs/cunningham_tables/main.gz is build-time data of upstream's cunningham_tables SPKG (with read_cunningham_prime_factors.py), installed nowhere; src/doc/en/developer/static/flowchart.dia is the dia source of flowchart.pdf; src/sage/graphs/generators/shortened_000_111_extended_binary_Golay_code_graph.pickle.xz is a pickled Sage graph used as doctest data; src/sage/repl/rich_output/example_jmol.spt.zip is a rich-output test fixture.
- Prescan PDFs: flowchart.pdf is built from the shipped flowchart.dia, src/doc/en/reference/parallel/media/map_reduce_arch.pdf from the shipped map_reduce_arch.fig, and prefix-tree-graphs-4.pdf and prefix-tree-partitions-5.pdf from the shipped .tikz files. complete-binary-trees-4.pdf has no TikZ source, but the docs embed its .png twin (src/sage/combinat/tutorial.py:195) and the PDF is referenced nowhere, so it is a leftover export rather than a shipped generated work.
- src/sage/repl/rich_output/example.pdf, src/sage/repl/rich_output/example.flv, src/sage/repl/rich_output/example.mkv, src/sage/repl/rich_output/example.webm and src/sage/repl/rich_output/example.wmv (with example.dvi, example.avi and the other example.* files) are the rich-output test fixtures of src/sage/repl/rich_output/, whose scene sources (example.canvas3d, example_wavefront_scene.obj/.mtl) are shipped; they are test data, not documentation built from absent sources.
- The 'rare wording' hits in ordinary source files are docstring prose, not licence terms: src/sage/arith/misc.py (eratosthenes and mqrr_rational_reconstruction described as slow/for educational purposes), src/sage/crypto/block_cipher/miniaes.py, src/sage/crypto/block_cipher/sdes.py, src/sage/crypto/public_key/key_exchange/finite_field_diffie_hellman.py and src/sage/crypto/public_key/key_exchange/sidh.py (toy/educational cryptography warnings), src/sage/ext/fast_callable.pyx ('you must not modify' an internal data structure), src/sage/geometry/hyperplane_arrangement/arrangement.py ('for educational use only') and src/sage/repl/rich_output/buffer.py (a readonly temporary file the caller must not modify).
- src/doc/common/_vendor/*.inv are Sphinx intersphinx inventories copied from the documentation of the named projects, used only while the manual is built; they hold object names and URIs, are not installed, and are covered by the src/doc stanza.
- Prescan rare wording: COPYING.txt:1226 is SQLite's public-domain dedication ('for any purpose, commercial or non-commercial'), not a restriction; build/pkgs/scipy/SPKG.rst:20 says SciPy's BSD licence allows commercial use; build/pkgs/giac/SPKG.rst:30 and build/pkgs/giac/spkg-src:57 note that Giac's French HTML documentation is non-commercial-only and that the SPKG removes it - no Giac sources or documentation are in this tree (Debian builds against system xcas); src/sage/interfaces/mathematica.py:551 describes Wolfram's own licensing of a program not shipped here.
- build/pkgs/csdp/LICENSE is the Common Public License text of an SPKG that is neither built nor shipped here (csdp is not in Build-Depends); src/sage/ext_data/pari/simon/.gp carry Denis Simon's GPL notice, and src/sage/ext_data/pari/buzzard/.g carry the author and provenance in prose without a licence line; both groups are installed as plain data under the Files: * GPL-2+ statement.
- src/LICENSE.txt and COPYING.txt read: upstream states original Sage code is GPL-2+ and documentation CC-BY-SA-3.0; COPYING.txt's claim that 'the whole Sage software distribution is licensed under GPL version 3 (no other versions!)' conflicts with the per-file GPL-2+ headers, and debian/copyright follows the headers.
- All of debian/ read: compat 13 via debhelper-compat, Rules-Requires-Root: no, hardening=+all, Standards-Version 4.7.4 against Policy 4.7.4.1, source format 3.0 (quilt), changelog in unstable closing #1058014 and #1059504, 38 patches with DEP-3 Description/Author headers grouped by purpose in series, install/docs/man/doc-base/desktop/icon files consistent, two autopkgtests (doctest, without-dev), no maintainer scripts.
- Build and runtime dependency names were spot-checked with apt-cache and all exist: libec-dev, libplanarity-dev, python3-numpy-dev (which provides dh-sequence-numpy3), python3-lrcalc, maxima-sage, python3-cysignals-bare, guess-concurrency, python3-cypari2, python3-memory-allocator, furo (which Depends python3-sphinx), and dh-sequence-sphinxdoc is provided by sphinx-common.
- The without-dev autopkgtest is safe: autopkgtest installs recommended packages only for tests declaring 'needs-recommends', so python3-sage's Recommends sagemath-dev is not pulled in (per the autopkgtest specification in the policy tool).
- uscan found upstream releases with
debian/watch; a newer upstream version is available (upstream11.0~beta6, packaged10.10), which is not a fault of the package. - Every pointer of
debian/copyrightto /usr/share/common-licenses names a file that is there (GPL-2,GPL-3,LGPL-2.1).
Not confirmed ◂
- I could not build the package or run its tests; the nocheck FTBFS is reasoned from debian/control, debian/rules and src/sage_docbuild/conf.py, not observed.
- Of the 235 holders the pre-review scan reports missing, I re-checked about fifteen (all absent) and did not verify the whole list; the scan matches names loosely.
- I did not open the binary media files (videos, .inv inventories, the PDFs' contents beyond text extraction), or example.dvi.
- The source of complete-binary-trees-4.pdf may exist outside the upstream tarball; only the tarball was checked.
Proposed changes ◂
None.
