Licensing needs to be clarified

[SnarkBoojum]

I'm working on packaging coq-serapi for Debian, and things are pretty annoying:

• the main LICENSE file says LGPL-2.1+ and GPL-3+ for most things that looks pretty clear
• but this LICENSE file says things about doc/* while there are no such files -- or did they move to notes/ ?
• again LICENSE says GPL-3+ / AGPL-3+ for sertop/* but that's not what I see in the files there ;
• that same LICENSE file claims to follow a Debian format -- it looks like it at the start, but it's diverging in ways automatic tools won't accept ;
• looking in jscoq/*, I see GPL-3+ ;
• looking in serapi/* serlib/* sertex/*, many headers start about the coq team and LGPL-2.1, and end with LGPL-2.1 and GPL-3+ (notice: not LGPL-2.1+).

I don't think a package for the code as-is stands any chance to enter Debian -- the question of licensing & copyright assignment is taken too seriously to accept such contradictory informations.

Can you clarify matters in the code then close this issue?

[palmskog]

@ejgallego if you want my opinion, I think the whole thing (code, documentation, etc.) should be dual licensed under LGPL-2.1-or-later and GPL-3.0-or-later. If this can't be done, e.g., because some code comes from Coq itself, then I think the whole thing should be LGPL-2.1-only.

[ejgallego]

Hi folks, indeed the current licensing situation is not good, thanks for bringing the issue into my attention.

I can't think about this today, but added to my todo list.

[ejgallego]

c.f. coq-community/apery#10

[ejgallego]

@SnarkBoojum I will first most of the issues, I think at this point I only have one question.

LGPL2.1 does allow you to also pick GPL2.1 and GPL3+ , by virtue of its clause 3, so I guess that indeed I should just write LGPL2.1 and not LGPL2.1+, right?

In fact, this is how the whole thing works, when you build sertop, the whole of it (which includes Coq) becomes GPL3 thanks to this licensing provision in LGPL2.1 IIUC. Is my reasoning correct?

[Zimmi48]

Yes, it is also my understanding that you can combine files under LGPL 2.1 and files under GPL 3+ and the overall thing is GPL 3+.

[ejgallego]

In fact you can combine or even relicense the whole of Coq to GPL 3 if you want, if I read the clause correctly.

[SnarkBoojum]

Well, I just know that when several license assignments apply to the same file (from the main LICENSE file, from the top of the file itself and from below in the file itself), that's just very confusing!

[ejgallego]

• it looks like it at the start, but it's diverging in ways automatic tools won't accept

@SnarkBoojum , what is the tool to check that LICENSE format is correct?

[SnarkBoojum]

The sentence lines 21 and 22 of LICENSE looks strange: shouldn't the start read "In some cases," ?

The tool to check the LICENSE file is named 'lintian'.

Thanks for the clarification!

[ejgallego]

The sentence lines 21 and 22 of LICENSE looks strange: shouldn't the start read "In some cases," ?

Thanks, fixed! Let me know if we need further fixes, I want to release today as the Coq Platform is waiting for a release hence the quick merge. I agree the wording was confusing, Coq and its derivatives are already GPL 3 if desired, I think now the file looks simpler.

The reason the jsCoq are GPL / AGPL 3 is to avoid people putting them as a service.

I am familiar with Debian licensing procedure (subscribed to debian-devel for more than a decade) , there should be no problem getting SerAPI in Debian.

The tool to check the LICENSE file is named 'lintian'.

Oh, I didn't think lintian for checking the license file, unfortunately I wasn't able to run it in the repos as is, not sure what the right set of options is.

If you can run it and send me the report I'll try to fix the problem.

[SnarkBoojum]

Ok, I finally packaged all deps for coq-serapi in Debian ; unfortunately, the licensing is still pretty... fuzzy.

Here are special notices:

1. LICENSE and coq-serapi.opam are contradictory ;
2. what those two files say isn't coherent with the file headers ;
3. I didn't know what to do about sertop/sertop_util.ml and serapi/serapi_protocol.ml, which might have a copyright from Jane Street and license Apache 2.0 !

Here is my current debian/copyright for the would-be package I don't feel confident to submit yet:

@ejgallego just to flag up that as per discussion on Zulip, this issue is preventing packaging of coq-lsp on Debian.

[ejgallego]

Thanks for the reminded, I didn't have time to work on this.

I'll push an update to update a couple of things:

• jscoq files are dead code, removing them
• will fix opam license field (indeed it should be LGPL 2.1+)
• will fix headers (or should we just remove them? That thing is fuzzy nowadays with version control)
• the small code we use from Jane Street is IMHO not problematic, but I will put this in its own file as to make it clearer, eventually such code will go away as we can now depend on base anyways (*)
• update the LICENSE file provided by @SnarkBoojum generously

(*) The historical reason I did copy some code from JS libs is that back in 2016, base didn't exists, and core was quite heavy, in particular when compiling sertop to javascript, due to Coq requiring -linkall that resulted in gigantic .js sizes.

[SnarkBoojum]

I guess only 8.19+0.19.0 will be fixed?

In that case, I guess I'll be able to rework my serapi packaging just after I'll have made the transition to Coq 8.19 in Coq.

[ejgallego]

Hi @SnarkBoojum , I'm happy to fix also older versions; lack of time is a problem tho. But I need to release a new 8.18 version.

[SnarkBoojum]

Coq 8.18 is in Debian and I think I'll start wondering about packaging coq 8.19 in about a week so that's why I'm interested in 8.19+0.19.0 - it would fit into my Debian work schedule.

[SnarkBoojum]

I found two remaining unclear things:

• LICENSE says sertop/js_sexp_printer.* has a Jane Street copyright, but the files there don't mention it.
• LICENSE doesn't mention A.Charguéraud's tests/genarg/libTactics.v, which is under LGPL-3.

That shouldn't prevent me from packaging for Debian, so I'll work on it ; here is the debian/copyright file of the would-be package:

     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.
  c. "Creative Commons Compatible License" means a license that is
     listed at http://creativecommons.org/compatiblelicenses that has

     (iii) in the case of broadcasts, the organization that transmits
     the broadcast.
  h. "Work" means the literary and/or artistic work offered under the
     terms of this License including without limitation any production

     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

  i. "You" means an individual or entity exercising rights under this
     License who has not previously violated the terms of this License

 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:
  a. to Reproduce the Work, to incorporate the Work into one or more
     Collections, and to Reproduce the Work as incorporated in the
     Collections;
  b. 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.";
  c. to Distribute and Publicly Perform the Work including as
     incorporated in Collections; and,
  d. to Distribute and Publicly Perform Adaptations.
  e. For the avoidance of doubt:
       i. 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;
      ii. 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,
      iii. 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:
  a. 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.
  b. 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.
  c. 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.
  d. 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
  a. 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.
  b. 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
  a. 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.
  b. 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.
  c. 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.
  d. 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.
  e. 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.
  f. 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.
