Comment 1 Neal Gompa 2016-07-26 08:44:12 UTC
Taking this review.

Comment 2 Neal Gompa 2016-07-26 08:51:05 UTC
I'd probably suggest that you need to tweak things slightly.

Fedora policy indicates that while private libs can go into %{_libdir}/snapd, helper programs and such should be in %{_libexecdir}/snapd (though %{_libdir}/snapd is allowed if it's not possible to make it work in the preferred path). In Fedora, %{_libexecdir} is defined as /usr/libexec. See the relevant macros for paths here: https://fedoraproject.org/wiki/Packaging:RPMMacros

Relevant guidelines on libexecdir: https://fedoraproject.org/wiki/Packaging:Guidelines#Libexecdir

I suspect that your --libdir is really supposed to be a --libexecdir, since I doubt you're interfacing with snap-confine via a C library to snapd.

Comment 3 Neal Gompa 2016-07-26 08:52:18 UTC
Also, you can replace "make %{?_smp_mflags}" with "%make_build", as it's cleaner and more obvious what it does. :)

Comment 4 Neal Gompa 2016-07-26 08:58:56 UTC
Please fix your file paths to use macros appropriately.

For example, for the udev rules, please use %{_udevrulesdir} instead of /usr/lib/udev/rules.d.

For /usr/lib/udev, just replace /usr with %{_prefix}.

In addition, the inclusion of "systemd" as a BuildRequires is only required when you need to actually run some programs from systemd in the build/test process. Otherwise, systemd-devel should be sufficient.

I think that *right now* it is irrelevant where snap-confine is, later on snapd will just have to agree as snapd and snap-confine. In other distributions this is done by installing everything to /usr/lib/snapd/*. If that cannot be done due to Fedora policy then it can be anything else as long as the snapd package just agrees on the effective location.

Yes. Let me tweak this. Thanks for spotting this. I bet it just works because there are no actual libraries and libdir implies setting libexecdir

Ack, will do

AFAIR I have systemd there because that defines one package config file that contains the location of udev rules directory. Iā€™m sure it is there for a reason.

Comment 7 Neal Gompa 2016-07-26 09:07:39 UTC
If you're depending on pkgconfig things, you can just set BuildRequires to those.

For example: "BuildRequires: pkgconfig(systemd), pkgconfig(libsystemd)" would resolve to the packages containing those pkgconfig files.

Those are the common/canonical names that are the same across all RPM-based distributions. If those don't resolve, they probably don't exist at all.

This stuff is important because the usage of libexecdir automatically marks a package as not multilib safe, which is important for preventing weird things happening when we create the x86_64 repository with multilib support.

Comment 9 Zygmunt Krynicki 2016-07-26 15:01:15 UTC
I've updated packaging to reflect this discussion. I hope I didn't miss anything.

The spec and SRPM file is at the same location as before.

You can have a detailed view of the changes I made here: https://github.com/zyga/snapcore-fedora/commits/master

Comment 10 Neal Gompa 2016-07-26 15:11:55 UTC
If you want, you can also change over the rest of the BRs, too...

glib2-devel -> pkgconfig(glib-2.0)
libseccomp-devel -> pkgconfig(libseccomp)

Otherwise, this looks good to me.

Package approved.

Comment 11 Neal Gompa 2016-07-26 16:12:15 UTC
Actually, there's still something left here...

Comment 13 Zygmunt Krynicki 2016-08-16 11:05:56 UTC
Hey Neal.

I've updated snap-confine, I believe most of the issues are now solved.

The updated spec file is: https://fedorapeople.org/~zyga/snap-confine.spec

SRPM with a patch inside: https://fedorapeople.org/~zyga/snap-confine-1.0.39-1.fc24.src.rpm

Please let me know if I need to adjust anything else.

Comment 14 Neal Gompa 2016-08-16 12:49:12 UTC
Two issues remaining:

* The license file isn't included in the package. The license file must be included using the %license macro. It works the same way as %doc, except since it isn't noted as a doc file, you can't tell RPM/DNF to not install it. So in the case of snap-confine, you need a "%license COPYING" in the file list section.

* Replace the ".gz" with ".*" for man pages in the file list. It is possible in the future that Fedora may change the compression format for man pages (to xz or something like that). Changing this will future-proof it for such changes.

Comment 15 Zygmunt Krynicki 2016-08-16 12:59:16 UTC
Ah, I used %doc out of habit. Updated the .spec file (I didn't push the SRPM again since I'm on capped network).

The updated spec file is: https://fedorapeople.org/~zyga/snap-confine.spec
