Re-posted from http://rakudo.org/2016/07/22/announce-rakudo-star-release-2016-07/
The release was prepared by Steve 'stmuk' Mynott

On behalf of the Rakudo and Perl 6 development teams, I'm pleased to announce the July 2016 release of "Rakudo Star", a useful and usable production distribution of Perl 6. The tarball for the July 2016 release is available from http://rakudo.org/downloads/star/.

This is the third post-Christmas (production) release of Rakudo Star and implements Perl v6.c. It comes with support for the MoarVM backend (all module tests pass on supported platforms).

Please note that this release of Rakudo Star is not fully functional with the JVM backend from the Rakudo compiler. Please use the MoarVM backend only.

Well today in the Moose-pen I am still going to have a look at my 33_conditions.t test case. In my last post I got all the little bits working right up to the point when I want the DAD to return or at least crate this string

RETRIEVE-->View-->'People'-->Elements-->'People.first_name',
'People.last_name','People.user_id'-->Condtion->People.user_id=test-->AND-->
People.first_name=John

After sleeping on it and then playing a bit I came to the very wise conclusion to not to test my Accessor in this way. If I take this path then I am opening myself up to going down all sorts of test rabbit holes where there is nothing wrong with my Accessor but a problem in my Tests DAD. So what to do?

Well lets have a look at what I have to test:

• coercion from a hash to a type works correctly
• class attribute values passed into the DAD are correct

For the people who use Windows, I've released berrybrew v1.04.

This software was originally written by David Farrell. While I was writing Test::BrewBuild, I needed some additional features (particularly the --with option for exec, and better PATH management). I wrote a couple of PRs, but they were rejected (not by David, but by the new maintainer). Not long after that, the person who had taken over the project disappeared, so I decided to permanently fork it, and nearly completely rewrite the whole thing.

It does everything the original does, but now includes far more:

HI! I continue blogging about sparrowdo - a simple perl6 configuration management tool.

This is what we've learned so far:

• Sparrowdo automation. Part 1. Installing cpan packages

• Sparrowdo automation. Part 2. Dealing with http proxy servers

Installing packages

Consider out latest example with installing CPAN packages:

Hey everyone,

Following is the p5p (Perl 5 Porters) mailing list summary for the past week. Enjoy!

So today in the Moose-Pen I was going to get my 33_conditions.t test case working. New we left off in my last post with this call to Accessor

Recently, I decided to undertake a quick little journey down to the Perl 6's Bug Queue. A quest for fame and profit—some easy game to hunt for sport. There's plenty of tickets, so how hard can it be? The quick little journey turned out to be long and large, but I've learned a lot of good lessons in the process.

PART I: The Newbie Contributor

Right away, I hit a snag. Some tickets looked hard. On some, it wasn't clear what the correct goal was. And some looked easy, but I wasn't sure whether I wanted to work on them just yet. While the ticket queue has the tag system, I needed some personal tags. Something special just for me....

The Ticket Trakr

So I wrote a nice little helper app—Ticket Trakr. It fetches all the tickets from the bug queue onto one page and lets me tag each of them with any combination of:

Thames Valley Perl Mongers, aka TVPM, are now having monthly social meetings at various locations in the Thames Valley (in the UK).

Our next meeting is next Monday (18th July) at 8pm, at The Jam Factory in Oxford. We're not going for the jam, but the beers.

Well back to clean up mode in the old Moose-pen today as I have completed my first round of changes to my Database::Accessor embedded classes. Just taking a quick peed at what might attributes might be missing from my I see that my Predicate is missing something important at least to any logical predicate. That is the ability to add parentheses to a predicate.

Well the way I see it I can just make this a Boolean flag attributes such as 'parentheses' but that takes a good deal of flexibility from the system. So what I am going to go for is two flags one for open and one from close, like this

Hello YAPC-ers,

Deadline seems to be quickly approaching, the Call for Speakers closes July 15th, 2016. But the good news is that you've got plenty of time to submit, prepare your talk && join us in Transylvania,

So come on, share your experience, amaze us with incredible ideas && practices. We want to have our minds blown about what we had never thought could be possible with Perl. We are looking for talks focused on all parts of Perl.

If you’re looking for inspiration, here it comes: hot Perl topics, hot tech topics (not limited to Perl, necessarily), trends & changes, Perl fundamentals, security, networking, testing, devOps, hardware, big data, Internet of Things, crazy hacks && ideas, gadgets && wearables, community talks, marketing or management talks, UI & UX, outreach programs, start-ups or other ideas you might have. Remember, this is YOUR conference!

This is a next post in Sparrowdo automation series.

The previous one was Installing CPAN packages.

Sometimes having internet restricted by http proxy usage could be a problem.

Recalling our latest post on installing CPAN packages, what if we have a server with http traffic only available under some http proxy server? Then we would fail to install any CPAN packages here, and would have a similar error from cpanm client:

$ cpanm CGI

! Finding CGI on cpanmetadb failed.
--> Working on CGI
Fetching http://www.cpan.org/authors/id/L/LE/LEEJO/CGI-4.31.tar.gz ... FAIL

Ok. Passing http proxy is possible when using sparrowdo. Let's get back to the cpan-package plugin.

The Perl NOC have informed the PAUSE admins that the CPAN Master is starting to get tight on diskspace. This is only a temporary constraint — at some point there will be a lot more space, but for now we need to free up some space.

A lot of space is being taken up by old releases, long since superseded. Please delete these old releases if you have some, and the NOC will stop being alerted.

Remember: everything you've ever released to CPAN will always be available in your BackPAN author directory. My PAUSE id is NEILB, so my BackPAN directory is:

backpan.perl.org/authors/id/N/NE/NEILB

Now in the Moose-pen we are coming to the home stretch of my Database::Accessor Classes, starting with 'Gather'. This one represents a fields in an in SQL 'Group by' clause, and in Mongo 'Group' stage.

Looking at it it really is just an array of predicate clauses so I think I can just drop this class altogether, which is always a good thing. So out it goes and the test as well. So that was easy.

Next it 'Filter' which is a 'Having' clause in SQL and I not 100% sure what it is in Mongo most likely something to do with group and project or maybe match? I guess it is up to the Mongo DAD writer to come up with that one.

Like 'Gather' this is just an array of predicates or the same as my 'Condition' class so I can just drop that one and its tests as well. So that is two classes I do not really need.

Every so often you find yourself requiring the download URL for a CPAN module. You can use the MetaCPAN API to do this quite easily, but depending on your use case, you may not be able to do this in a single query. Well, that's actually not entirely true. Now that we have v1 of the MetaCPAN API deployed, you can test out the shiny new (experimental) download_url endpoint.

Dancer 0.200003 is on its way to a CPAN mirror near you. I'd like to give a big shout out to the rest of the Dancer core team and our awesome community members for their work in bringing this release to fruition.

There are several changes in particular worth noting:

- There is a security fix for Dancer2::Session::YAML that prevents accepting a bad session cookie value from the client. Thanks SysPete!

- There was a swift response to the breakage caused by YAML 1.16. Originally, we patched Dancer2 to require a minimum version of 0.86 and a maximum version of 1.15. Thankfully, YAML was patched and updated, and Dancer2 will again work with the latest YAML.pm.

For your convenience, here's the full changelog:

I posted previously about a new "starter" bundle for Dist::Zilla, the CPAN author's automation tool. I'd like to briefly try to answer the question: "Why should I care?"

If you're already happily using Dist::Zilla with an extensive configuration or plugin bundle of your own, this bundle isn't for you. But maybe you can get some ideas from the included plugins, I added a few to my author bundle!

If you're looking to get started in Dist::Zilla, the [@Starter] bundle makes a great starting point. Usage is similar to [@Basic] and all of the same information in the dzil.org tutorial applies.

The next class in the Moose-pen is Database::Accessor::Link which would represent a 'Join' in SQL and a I think they call it a 'Pipe Lookup' in Mongo or it could mean a find on a document buried under the parent document. I guess that is a topic for a later post.

The first thing I noticed was this class and the 'Condtion' class I looked at yesterday is they share the same 'predicates' attribute. So being a good Mooser the first thing to day is to pull that attribute out and add it into a role.

So after a few copy and pastes and a little typing I have

As I was tagging tickets in my bug ticket helper app, I was surprised by how often I was tagging tickets with this particular tag:

It may have been the most used tag of them all. And so, it made be think about...

PART II: The Experienced Contributor

I will be referring to "core developers," but this generally applies to any person who has great familarity with the project, how it should, does, and will work —The Experienced Contributor. When it comes to bug queues, can this type of people do more than just pick the bug they like the most and fix it?

LESSON 3: Many Tickets Can Be Fixed With A Single Comment

On my date with the bug queue, I found many tickets that looked relatively easy to fix, from a technological point of view, but I couldn't even begin working on them for a simple reason: I didn't know what the correct behaviour should be.

Here I start a series of posts on sparrowdo configuration management tool usage.

Installing sparrowdo

Sparrowdo implies installing software on both master and target host. Following "push" approach one should install a sparrowdo on master host where from he starts a ssh sessions against target hosts to be configurable:

$ ssh master.host 
$ panda install Sparrowdo

Once you install a sparrowdo you need to install a sparrow client on every host where you want to start deployments. Sparrow acts like client to carry out deployment tasks initiated from master host.

$ ssh target.host 
$ cpanm Sparrow
$ yum install curl

Here is simple schema of master -> target hosts interaction:
