I'll take this for a review!

* Use virtual rubygem provides
  - In you spec file, you are using "BuildRequires: rubygem-rspec", but this
    would be nice to replace by "BuildRequires: rubygem(rspec)"

* Simlify %prep section
  - First of all, it is the best to do all the custom steps you need at the end 
    of the %prep section. In that case, you are already in the right directory
    and you can remove the pushd/popd stuff.
  - Secondly, I would suggest to move the rpmlint fixes to %install section.
    In this specific case, they are harmless, but it might happen that different
    modification will cause troubles with gem rebuild done in %build section

* rpmlint fixes
  - I would suggest to delete the shebang ling instead of commenting it out. It
    might be completely harmless, but I have the feeling that it might cause some
    issues (but I might be totall wrong as well ;))
  - It would be nice to report the fixes upstream. In case you have already
    reported them, please provide link, so anybody can check next time what
    is the status.

* Bundled library
  - It seems that this package bundles libev. Is there any chance to use the
    system version of libev instead [1]? Or in the worst case provide the
    "bundled" virtual provide.


Please resolve the issues prior we'll continue.

Hi, Vit

Thank you for your review!! This is in detail, and clear for me.
I updated my spec and srpm files for your review. The URLs is same with previous review.

Koji: http://koji.fedoraproject.org/koji/taskinfo?taskID=13376459

Can you do review again?

Also let me comment for your review comment.

I got it. I updated to use "BuildRequires: rubygem(rspec)".

Yes. I moved the rpmlint fixes to end of %install section.

I deleted the shebang line in Rakefile by sed command.
And add the reported URL as a comment to spec file.

I tried to separate bundled libev and using system libev (libev-devel). And I suceeded to compile the nio4r with system libev, and to pass almost all the rspec test cases.
But when I compared the bundled libev (version 4.22) and original source [1], I found that the bundled libev had individually modified. [2][3]

So, finally I made a choice to use "bundled(<libname>) = <version>".

Also let me post the difference from previous review, as a reference. [4]

Once this gets into Fedora, could you please mention this virtual provide here:

https://fedoraproject.org/wiki/Bundled_Libraries_Virtual_Provides

Seems there was some changes in this policy like 6 weeks ago.




Also a few more nits:

* Please bump the release
  - It is good habit to bump the release every iteration, update %changelog
    as well as provide updated SRPM. That way, I can always check the progress
    since last time.(In reply to Jun Aruga from comment #3)

* Better inline comments
  - I would suggest to replace your comment:

      # Fix the issue for rpmlint
      # I reported it to upstream, and its fix was merged to master branch.
      # https://github.com/celluloid/nio4r/pull/86

    by something more explanatory, e.g.:

      # Remove useless shebang.
      # https://github.com/celluloid/nio4r/pull/86

    I don't think that reference to rpmlint is useful there.

  - This note applies generally, also to other similar comments ;)

* License
  - Due to bundled libev, I think the license field should be updated. The
    libev license appears to be (BSD or GPLv2+) while the code of the rest of
    the package is MIT, the license tag should be:

      MIT and (BSD or GPLv2+)

Hi, Vit

I modified your mentioned points.
Could you check below updated files?

Spec URL: http://people.redhat.com/jaruga/git/rubygem-nio4r/rubygem-nio4r.spec
SRPM URL: http://people.redhat.com/jaruga/git/rubygem-nio4r/rubygem-nio4r-1.2.1-1.fc25.src.rpm
Description: New IO for Ruby.
Fedora Account System Username: jaruga
Koji: http://koji.fedoraproject.org/koji/taskinfo?taskID=14712271

Thanks.

* Swap the description and summary
  - It seems that the description and summary are swapped. Could you swap them
    in the .spec file please?


But since this is only minor issue, I APPROVE the package. Please don't forget to update the "bundled libraries" page once you get this package into Fedora.


[1] https://fedoraproject.org/wiki/Bundled_Libraries_Virtual_Provides

Vit, thanks for your reivew.
I did swap the description and summary, bumped the release, and updated above files in the URL.

I am going to add this package "bundled libraries" after that.

Package request has been approved: https://admin.fedoraproject.org/pkgdb/package/rpms/rubygem-nio4r

Pushed to master, built, and updated the wiki.
