Comment 1 Otto Liljalaakso 2021-03-17 10:29:25 UTC
Initial comments:

1. To ensure correct ordering in case of updating from snapshot to newer snapshot, version string should include date. Reference: https://docs.fedoraproject.org/en-US/packaging-guidelines/Versioning/ section Snapshots
2. Patches should link to patch/issue/pull request/something where the patch is upstreamed, or explain why the patch is Fedora specific. Reference: https://docs.fedoraproject.org/en-US/packaging-guidelines/PatchUpstreamStatus/

I will continue later.

Comment 2 Elliott Sales de Andrade 2021-03-17 20:03:56 UTC
gumbo-parser is already packaged; you should probably unbundle it, but at the very least not clobber the existing files.

Comment 3 Otto Liljalaakso 2021-03-17 20:37:41 UTC
A couple of findings more:

3. When I try to build from srpm in Koji, I get the following error:
   
     /bin/sh: line 1: xxd: command not found

  Build command was this:

     $ koji build --scratch f35 litehtml-0.5-1.gitdb7f59d.fc35.src.rpm

  and logs are at https://koji.fedoraproject.org/koji/taskinfo?taskID=63994712

  Is BuildRequires: vim-common missing?

     $ dnf repoquery --whatprovides /usr/bin/xxd
     vim-common-2:8.2.1770-1.fc33.x86_64
     vim-common-2:8.2.2607-1.fc33.x86_64

  (Strange by the way, I do not understand how vim is involved with this.)

4. I agree with Elliott about (un)bundling gumbo. Upstream should be contacted about this, too. Reference: https://docs.fedoraproject.org/en-US/packaging-guidelines/#bundling

5. I see some tests available upstream, but there is no %check in the spec file. The tests should be run if possible. Reference: https://docs.fedoraproject.org/en-US/packaging-guidelines/#_test_suites, also discussion of %ctest macro in https://docs.fedoraproject.org/en-US/packaging-guidelines/CMake/ may be relevant

Comment 4 Otto Liljalaakso 2021-03-17 21:27:25 UTC
6. Gumbo Parser is licensed with Apache Software License 2.0. If unbundling it (item 4) cannot be done, the License must be marked as 'BSD and ASL2' and full license text included. Note that upstream is currently violating Gumbo's license by not including the full license text as required by its terms — they should be informed about this situation, too. Reference: https://docs.fedoraproject.org/en-US/packaging-guidelines/LicensingGuidelines/#_license_text

Comment 6 Otto Liljalaakso 2021-03-21 10:14:58 UTC
Good progress!

After the latest updates, fedora-review ran to completion, so review can progress. 

7. The source tree comes bundled with tools/xxd.exe. This Windows binary is of course useless, and brings more licensing issues, since the Vim license [1] also requires including a copy. Could also that be removed from in %prep?

I have to admit being a little lost regarding the license violations: Bad items can be removed in %prep, but they still end up in the srpm. Is that a problem? I sent a question to the packaging mailing list about this [2])

8. Changelog formatting is slightly off: Character '-' should be used between version and release parts. Reference: https://docs.fedoraproject.org/en-US/packaging-guidelines/#changelogs (also, I do not think it is necessary to keep a changelog for changes made during review — but not wrong either, if you prefer to have those)

9. fedora-review spotted discrepancy between given spec and srpm:

    [!]: Spec file according to URL is the same as in SRPM.
         Note: Spec file as given by url is not the same as in SRPM (see

Comment 7 Otto Liljalaakso 2021-03-21 15:14:55 UTC
I have completed the review. Review report below. It includes all remaining issues, also those that have been discussed in earlier comments.

Package Review
==============

Legend:
[x] = Pass, [!] = Fail, [-] = Not applicable, [?] = Not evaluated

===== List of MUST issues =====

[!]: Changelog in prescribed format.
     Note: Should use '-' between version and release
[!]: Sources contain only permissible code or content.
     Note: gumbo license text missing, xxd.exe license is unclear. See packaging
     mailing list discussion for solution options:
     https://lists.fedoraproject.org/archives/list/packaging@lists.fedoraproject.org/thread/HPVIZZW2U6LJUGW6UKQOKPDLHBVYOQJY/

[!]: Patches link to upstream bugs/comments/lists or are otherwise
     justified.
     Note: litehtml_unbundle-gumbo.patch has not been sent upstream. It would be good to
     have an option in upstream buildsystem to prevent building bundled
     dependencies and rely on that. The link should point to that pull request/
     issue/discussion.

I've submitted a PR for the unbundling patch at https://github.com/litehtml/litehtml/pull/149

Comment 9 Otto Liljalaakso 2021-03-23 13:25:10 UTC
Great progress!

The only remaining thing is source rpm licensing. I think it would be the best if upstream could be convinced to do the following:

1. Add copy of the Gumbo license in the repository. README.md already mentions Gumbo's licensing and all source files start by declaring the Apache Software License 2.0. But, the license conditions require attaching a copy of the license, not just linking to it.
2. Clarify the situation of xxd.exe licensing (most probably it is the Vim license, but it is the best let upstream say what it is, because they should know where they got it from) and add its license text.

If that is not possible, then the source rpm must be modified. See the mailing list discussion linked above for option. (Hopefully upstream agrees to clarify its licensing and we do not have to do this.)

Comment 10 Otto Liljalaakso 2021-03-23 13:26:36 UTC
One more tiny thing. I suppose this comment is not relevant any more, since upstream accepted the so versioning patch? At least wording could be updated, since the named patch does not exist any more.

> # WARNING: Update soversion in litehtml_soversion.patch if necessary!

Upstream has accepted my PR to add license texts for gumbo and xxd, and also to drop the precompiled xxd binary, bundling it as source code instead.

Nice! Great co-operation with upstream. Package approved! Let me know if you need any help with anything. Otherwise, thank you and best wishes for the rest of the process!
