Successful koji build task:

I had to remove the ppc64 architecture due to go/golang incompatibility.

 - Take a look at https://fedoraproject.org/wiki/More_Go_packaging to package Go apps

 - You need to unbundle vendor/ first, which implies packaging several libraries. Use gofed to help you (install and use the version from updates-testing if you're on F27).

 -Shouldn't be necessary:

%define debug_package %{nil}

 - Don't do that:

#Gzip man pages
/usr/bin/gzip %{_builddir}/%{name}-%{version}/doc/man/*

  Compressing man pages is handled by the packaging process

 - Don't put .gz as the compression can change in the future:

%{_mandir}/man1/restic*.*

 - Don't mark man pages as doc

 - Own the directories you create with %dir:

%dir %{_datadir}/zsh/site-functions
%{_datadir}/zsh/site-functions/_restic
%dir %{_datadir}/bash-completion/
%dir %{_datadir}/bash-completion/completions
%{_datadir}/bash-completion/completions/rest

 - Don't install doc that way, just use %doc directly with the files:

%files devel -f devel.file-list
%license LICENSE
%doc GOVERNANCE.md CONTRIBUTING.md CHANGELOG.md README.rst 

 - Don't install from %{_builddir}/%{name}-%{version}/ : when you are in %build or %install, you are in the folder where the archive has been extracted, so you have access directly to the files you wanna install.


Here's a sample I've created based on the Gofed output. I have not tested it.

* Wed Jun 13 2018 Steve Miller <copart> - 0.9.1-1
- First package for Fedora



 - You can look at: https://eclipseo.fedorapeople.org/golang/ for more examples if you need help packaging the dependencies.
  Search on https://src.fedoraproject.org/ to see what dependencies are already packaged and which one are missing.
  I suggest trying to build all deps within your COPR and see if restic builds then. 


Don't hesitate to contact me for help on my email.

Also I'm not able to sponsor, try introducing yourself to the devel mailing list and do some informal reviews to show that you understand the guidelines

You don't have to be a sponsor to approve a review ticket from someone who needs a sponsor.  See the end of https://fedoraproject.org/wiki/How_to_get_sponsored_into_the_packager_group#Submitting_quality_new_packages

I now have the build working in Copr with the information/help provided by  Robert-André.

I created FIVE new packages that restic depends on that are not already in the repos.  These five new packages do not build in EPEL since the new Go macros are not available yet.

Dependencies:
golang-github-elithrar-simple-scrypt-devel
github-kurin-blazer-devel
golang-github-minio-minio-go-devel
github-pkg-xattr-devel
golang-github-restic-chunker-devel

All spec files:
https://github.com/copart/restic-rpm/tree/master/SPECS

Packages in Copr:
https://copr.fedorainfracloud.org/coprs/copart/restic/packages/

I cannot test building restic in koji due to the dependencies.

I am open to ALL feedback.  Thank you to all those that already responded to this request!

Each SPEC requires their own review request. File a bug for each.

Quick notes though:

https://github.com/copart/restic-rpm/blob/master/SPECS/golang-github-elithrar-simple-scrypt.spec 
https://github.com/copart/restic-rpm/blob/master/SPECS/golang-github-kurin-blazer.spec
https://github.com/copart/restic-rpm/blob/master/SPECS/golang-github-pkg-xattr.spec
https://github.com/copart/restic-rpm/blob/master/SPECS/golang-github-restic-chunker.spec

→ split the description to stay below 80 characters per line
→ Version: 1.3.0 should be after goipath and before %gometa


https://github.com/copart/restic-rpm/blob/master/SPECS/golang-github-minio-minio-go.spec

→ %gochecks probably won't work as there is no internet access when building from within Koji or Mock

Robert-André I added review requests for all dependencies.  I also update the SPECs as you suggested.  Thank you!

Updated SPEC and SRPM
Spec URL: https://copart.fedorapeople.org/restic/restic.spec
SRPM URL: https://copart.fedorapeople.org/restic/restic-0.9.1-2.fc29.src.rpm
koji: https://koji.fedoraproject.org/koji/taskinfo?taskID=27838154

ALL dependencies are now available in rawhide and this package builds.  Therefore, I believe this is ready for review.

 - Add a new line between each changelog entries

 - rm -rf vendor in %prep

 - build fails, probably because of:

BUILDSTDERR: # github.com/restic/restic/internal/backend
BUILDSTDERR: internal/backend/backend_retry.go:37:23: undefined: backoff.WithMaxRetries

WithMaxRetries was added in version 2.0.0 of golang-github-cenkalti-backoff, latest version packaged in Fedora is 1.1.0. The problem wasn't apparent because you didn't remove vendor.


I'll see if I can do a PR to update it and get back to you.

https://src.fedoraproject.org/rpms/golang-github-cenkalti-backoff/pull-request/1

Dependency golang-github-pkg-sftp requires a bump with upstream to support restic.  Submitted a PR to update it.

The restic package needs an update to use WithMaxRetries
https://bugzilla.redhat.com/show_bug.cgi?id=1590921#c9

PR: https://src.fedoraproject.org/rpms/golang-github-pkg-sftp/pull-request/1

Updated SPEC and SRPM
Spec URL: https://copart.fedorapeople.org/restic/restic.spec
SRPM URL: https://copart.fedorapeople.org/restic/restic-0.9.1-2.fc29.src.rpm
koji: https://koji.fedoraproject.org/koji/taskinfo?taskID=28665487

ALL dependencies are now available in rawhide, vendor folder is removed, and this package builds.  Therefore, I believe this is ready for review.

 - Add OFL to the license list for the provided Lemon font, and add a comment explaining the license breakdown.



Package otherwise approved.
