Description Dave Love 2016-04-29 16:13:19 UTC
Spec URL: https://loveshack.fedorapeople.org/review/singularity.spec
SRPM URL: https://loveshack.fedorapeople.org/review/singularity-1.0-6.e7409ff5.el6.src.rpm
Description: 
Singularity is a portable application stack packaging and runtime utility.

There are several methods to implement portable application stacks at
present. Among them are containers and virtual machines. When using these
solutions to package a single application (or application stack), one ends
up having to manage the entire operating system overhead (security, updates,
size/bulk, etc..) just to distribute a single application or workflow. While
virtual machines and containers have strong usage benefits, application
portability and distribution is not an efficient use of these technologies.

Singularity works on a completely different perspective. Contrary to building
and managing an entire operating system environment (for the sake of
portability and reproducibility of an application stack), Singularity works
on the opposite premise. By configuration of an application stack spec via a
configuration file, coupled with automatic dependency resolution to achieve
portability, Singularity can create minimalistic singlet "app" which can
easily be copied from system to system and run using Singularity on different
systems.

Comment 1 Orion Poplawski 2016-04-29 18:28:11 UTC
Initial comments:

- Drop the blank line after %description
- No more need for %{?_licensedir}

Comment 2 Dave Love 2016-05-03 10:43:43 UTC
Oh; I thought blank lines after section headers were elided.  I better modify rpm-spec-mode to DTRT with paragraphs instead.

You need the license conditional with SCLs.  That's quite relevant in this case (e.g. bundling a python33 application for el6).

I noticed an obsolete comment about selinux, which I'll remove.

By the way, is there a recommended way to conditionalize use of a github snapshot v. a proper release?

Comment 3 Dave Love 2016-05-06 12:46:18 UTC
Singularity is changing radically, so this should go on hold for now.

Comment 4 Dave Love 2016-06-08 17:04:31 UTC
I think it's worth restarting review with v2.0:

Spec URL: https://loveshack.fedorapeople.org/review/singularity.spec
SRPM URL: https://loveshack.fedorapeople.org/review/singularity-2.0-4.el6.src.rpm

Comment 5 Orion Poplawski 2016-06-10 17:30:21 UTC
Looks really good.  Minor nits:

I would do:

# For non-releases
%global commit 5440d34a550aa155dc9245a3f8f9d7f09948695d

and then comment out like:

#global commit 5440d34a550aa155dc9245a3f8f9d7f09948695d

when not using.

Git snapshots should have "git" in the release string:

Release: 4%{?shortcommit:.git%shortcommit}%{?dist}

See https://fedoraproject.org/wiki/Packaging:NamingGuidelines#Snapshot_packages

personally, I would keep the version name of the downloaded git snapshots, but that's preference.

Looks like upstream has fixed the rpmlint setgroups issue.

Comment 6 Dave Love 2016-06-11 11:51:15 UTC
The snapshot stuff may not be relevant now, but I kept and modified it; I must have misread the naming guidelines before.
This version is patched for the security warnings.

Dave you got your + review flag, no need for more iterations for the review ;)
