Hi all,

 

What are people's thoughts on CPAN and Carton (the Perl version of Bundler,
Composer, NPM, etc)? 

 

I like the idea as a way of more easily managing Perl dependencies
regardless of Linux distribution and version; in other words, we could
provide the same dependencies regardless of being on Debian Jessie/Debian
Stretch/Debian Buster or Ubuntu or Fedora or RHEL or OpenSUSE.

 

I suppose the difficulty is how we do a community-friendly deployment? I see
two main options:

1.      Have the Debian package run "carton install" automatically during
install/upgrade

a.      This could be error prone and difficult to support.

2.      Have the Koha Debian Package Manager run "carton install" when
building the package, and embed the Perl modules in the Koha package 

a.      It's unknown how much this would increase the size of the Koha
package

 

It looks like there is some precedence within Debian for embedding modules
in a Debian package:

I think Debian and Ubuntu would (and perhaps should) still be first class
citizens, but it would mean it would be easier to have RPM packages too -
whether they're official, semi-official, or unofficial. I have a lot of
experience building RPM packages for CentOS/RHEL and OpenSUSE, so I'd be
willing to be involved in some capacity there.

 

I think retaining Debian packages is important, because we have a number of
non-Perl dependencies, and the Debian packages provide a lot of very useful
automation. 

 

Anyway, please share your thoughts. Victor and Martin brought it up on
#koha, and I figured I'd continue the conversation here. 

 

Personally, I'm moving away from packaging Perl dependencies as Debian
packages for non-Koha projects, because it makes porting the projects to a
newer version of the same OS much more difficult. 

 

I know using Debian's Perl packages have a lot of advantages, as they're
tested, reviewed, and patched, but I think it might be time to consider a
change.
