My thanks go to everyone who participated on this great conference and helped this event happen!
Recently in Debian Category
When I showed Benjamin (a college of mine) my TPF 2010Q3 grant proposal, we slipped to a discussion about deploying Perl software. Nice (and recent) list of different approaches can be found @modernperlbooks.com. To sum it up => TIMTOWTDI. Which is good, but none of those is perfect. The Perl+CPAN world is way too complex.
During out discussion with Benjamin I proposed an idea of shipping the application altogether with the OS. Insane? The base Debian system is ~190MB, all the rest is needed for the application. Then deployment will be a matter of running this system on a virtual machine, somewhere in the cloud or in a simple chroot. (btw any Linux distribution can have any other Linux distribution working in a chroot) The files will never clash, all the "machines" would be dedicated. No fear of putting files where they belong to.
dpkg-scanpackages: info: Wrote 2898 entries to output Packages file. dpkg-scansources unstable /dev/null > unstable/Sources bzip2 -c9 unstable/Packages > unstable/Packages.bz2 gzip -c9 unstable/Packages > unstable/Packages.gz bzip2 -c9 unstable/Sources > unstable/Sources.bz2 gzip -c9 unstable/Sources > unstable/Sources.gz dpkg-scanpmpackages processing unstable/Packages.bz2 apt-ftparchive -c=Release.conf release unstable > unstable/Release rm unstable/Release.gpg gpg -abs -o unstable/Release.gpg unstable/Release real 11m14.629s user 1m45.227s sys 1m56.679s
The dpkg-scan* tools are probably not the best solution for such big repository having 2898 packages in one folder..., but given enough patience it works! :-)
Xacobeo a Perl GUI to visualize XML and perform XPath queries just entered Debian unstable - http://packages.debian.org/sid/xacobeo.
So the Perl QA Hackathon 2010 is over. My part in it was mainly to help with organizing, but with a specification from Gregoa and a help from Potyl a new debian-perl quality script was created - patchedit.
Patchedit works in two modes edit and check. In the edit mode it will fire-up an editor and optionally add a missing patch description fields. In the check mode it can test the fields and output TAP based on the ok/fail. Thanks to this and TAP::Formatter::HTML it was easy to create a page with the patch "health" status. Here is how:
find -name series | perl -MIO::Any -MFile::Basename=dirname -ne 'chomp; my $s = $_; my $bd=dirname($s); my @pl=map { $bd."/".$_ } grep { $_ !~ m/^\s*$/ } map { chomp; $_ } split("\n", IO::Any->slurp($s)); print map { $_."\n" } @pl;' | xargs prove --exec "patchedit check -o" -m -Q --formatter=TAP::Formatter::HTML > output.html
The output page can be found here.
You can watch the final stand-up video with the achievements at brian d foy blog.
I didn't know about this easy way to locate Perl modules in Debian packages.
$ dh-make-perl --locate Foo::Bar Using cached Contents from Fri Mar 26 10:25:51 2010 Foo::Bar is not found in any Debian package $ dh-make-perl --locate Moose::Meta::Class Using cached Contents from Fri Mar 26 10:25:51 2010 Moose::Meta::Class is in libmoose-perl package $ dh-make-perl --locate Test::More Using cached Contents from Fri Mar 26 10:25:51 2010 Test::More is in Perl core (package perl) since 5.6.2
So there is a ready made solution how to locate Perl modules in Debian packages. The '--locate' option is in Squeeze (testing) version of dh-make-perl or in the source repositiory.
