This was recognised several years ago and discussions for a new system had already begun, with the view that reports should be submitted via HTTP.</p><p>At the Oslo QA Hackathon in 2008, David Golden and Ricardo Signes devised the Metabase, with the design work continuing at the Birmingham QA Hackathon in 2009, where David and Ricardo were able to bring others into the thought process to work through potential issues and begin initial coding. A number of releases to CPAN and Github followed, with more people taking an interest in the project.</p><p>The Metabase itself is a database framework and web API to store and search opinions from anyone about anything. In the terminology of Metabase, Users store Facts about Resources. In the Metabase world, each CPAN tester is a User. The Resource is a CPAN distribution. The Fact is the test report. Today that&#8217;s just the text of the email message, but in the future it will be structured data. The Metabase specifies data storage capabilities, but the actual database storage is pluggable, from flat files to relational databases to cloud services, which gives CPAN Testers more flexibility to evolve or scale over time.</p><p>Meanwhile the CPAN Testers community was also attracting more and more interest from people wanting to be testers themselves. As a consequence the volume of reports submitted increased each month, to the point that the perl.org mail server was struggling to deal with all the mailing lists it hosted. The cpan-testers mailing list was submitting more posts in one day than any other list submitted in a month (in a year in some cases). Robert and Ask, very reasonably, asked if the testers could throttle their submissions down to 5k report posts a day, and set a deadline of 1st March 2010 to switch off the mailing list.</p><p>David Golden quickly took on the task to envisage a project plan, and work began in earnest in December 2009. With less than 3 months to the cut-off date, there was a lot of work to do. David concentrated on the Metabase, with Barbie working on ensuring that the current cpanstats database and related websites could move to the Metabase style of reports. Despite a lot of hard work from a lot of people, we unfortunately missed the 1st March deadline. Having throttled report submissions to a more manageable level, and although not complete, the target for HTTP submissions was in sight, Robert and Ask were very understanding and agreed to keep us going a little while longer.</p><p>Throughout March and April a small group of beta testers were asked to fire their submissions at the new system. It ironed out many wrinkles and resulted in a better understanding of what we wanted to achieve. The first attempts at retrieving the reports from the Metabase into the cpanstats database began in April, and again highlighted further wrinkles that needed to be addressed. After a month of hard testing and refinement, we finally had working code that went from report submission by a tester, storage into the Metabase, retrieval into the cpanstats database and finally presentation on the CPAN Testers family of websites.</p><p>During June the process was silently switched from testing to live, allowing reports to be fed through into the live websites. Due to the ease with which the new style reporting fit into the existing system, the switch largely went unnoticed by the CPAN testers community as well as the Perl community. A considerable success.</p><p>The CPAN Testers eco-system is now considerably larger than those early days of simply submitting handwritten reports by email to a mailing list, and the work to get here has featured a cast of thousands. Specifically for CPAN Testers 2.0, the following people have contributed code, ideas and effort to the project over the past six months:</p><ul> <li>Andreas K&ouml;nig</li><li>Apocalypse</li><li>Ask Bj&oslash;rn Hansen</li><li>Barbie</li><li>Chris Williams</li><li>Dan Collins</li><li>David Cantrell</li><li>David Golden</li><li>Florian Ragwitz</li><li>H.Merijn Brand</li><li>Jon Allen</li><li>Lars D&#618;&#7431;&#7428;&#7435;&#7439;&#7457; &#36842;&#25289;&#26031;</li><li>L&eacute;on Brocard</li><li>MW487</li><li>Nigel Horne</li><li>Ricardo Signes</li><li>Richard Dawe</li><li>Robert Spier</li><li>Serguei Trouchelle</li><li>Shlomi Fish</li><li>Slaven Rezi&#263;</li></ul><p>Barbie and David would like to thank everyone for their involvement. Without these guys CPAN Testers 2.0 would not have been possible. Thanks to everyone, we can now look forward to another 10 years and more of CPAN Testers.</p><p> <a href="http://www.cpantesters.org/">CPAN Testers</a> now holds over 7.5 million test reports covering nearly 11 years worth of testing Perl distributions. There have been over 1,000 testers in that time, and every single one has helped the CPAN Testers project to be the largest single community supported testing system of any programming language. For a full list of everyone who has contributed, visit the <a href="http://stats.cpantesters.org/testers.html">CPAN Testers Leaderboard</a>. A huge thank you to everyone.</p><p>With the Metabase now online and live, we can now announce an absolute deadline to close the mailing list. This is currently set as 31st August 2010. After this date all submissions via email will be rejected, and testers will be encouraged to upgrade their testing tools to take advantage of the new HTTP submission system. Many of the high volume testers have already moved to the new system, and we expect nearly everyone else to move in the next month. We will be tailing the SMTP submissions to catch those who haven't switched, such as some of the more infrequent testers, and warn them of the deadline.</p><p>More work is planned for CPAN Testers, from further validation and administration of reports, to providing more functionality for alternative analysis and search capabilities.

Unlike other similar Java-based tools, Hudson is language-agnostic, even well-integrated with other tools.For Perl<br>projects, with a little assistance from CPAN, it's easy to set up and use for Perl projects. We'll look at a sample setup that covers most of the bases, including a few pointers on making it easy to build and track things<br>under Hudson, and finish up with a look at using Hudson to get your team involved - even enjoying - continuous integration.</p><p>Announcement posted via App::PM::Announce</p><p>RSVP at Meetup - <a href="http://www.meetup.com/San-Francisco-Perl-Mongers/calendar/13762958/">http://www.meetup.com/San-Francisco-Perl-Mongers/calendar/13762958/</a></p> Phred 2010-06-10T20:01:52+00:00 journal Smokebrew - It is like perlbrew but different http://use.perl.org/~BinGOs/journal/40386?from=rss <p>Published over at <a href="http://blogs.perl.org/users/bingos/2010/06/smokebrew---it-is-like-perlbrew-but-different.html">blogs.perl.org</a> </p> BinGOs 2010-06-08T14:50:38+00:00 journal JVM's -XX:-DontCompileHugeMethods &amp; dynamic languages http://use.perl.org/~jjore/journal/40367?from=rss <p>In <a href="http://nerds-central.blogspot.com/2009/09/tuning-jvm-for-unusual-uses-have-some.html">http://nerds-central.blogspot.com/2009/09/tuning-jvm-for-unusual-uses-have-some<nobr>.<wbr></nobr> html</a> which I just picked out of reddit.com's front page I notice there's an ordinary 8K bytecode size limit for JVM heuristics.</p><p>Allegedly adding -XX:-DontCompileHugeMethods to the command line eliminates this limit.</p><p>In "current" versions of JVM which don't have the very new invokedynamic bytecode operation and languages implemented on top of the JVM like JRuby, I assume their implementation does all the dynamism as ordinary code.

I thought it'd be nice if I could step through the test with the debugger and just stop whenever a test failed.</p><p>Here's the result. A test failure immediately followed by being in the debugger:</p><blockquote><div><p> <tt>not ok 236<br>14:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return $result;<br>&nbsp; DB&lt;1&gt;</tt></p></div> </blockquote><p>and then I could ask for the stack trace which is nice:</p><blockquote><div><p> <tt>&nbsp; DB&lt;1&gt; T<br>. = main::ok(undef) called from file `t/02_methods.t' line 796<br>. = main::check_tar_extract(ref(Archive::Tar), ref(ARRAY)) called from file `t/02_methods.t' line 507</tt></p></div> </blockquote><p>I wrote the below snippet to automatically stop the debugger whenever something like ok() failed.

Bob used Perl's Artistic 1.0 license on some Java code to manage model trains. The code was later patented by an Oregon-based company(!) and then Bob got sued(!!) for Bob distributing the other company's patented code(!!!). The good part of the story is that this is the first test at the US Federal Appeals Court level for an open source license to be enforceable even if no money exchanges hands, and... we won! <p> Bob spent a lot of time and money on the case though.

Simple forms can be rendered, parameters can be parsed, data can be validated, and validated data can be submitted to your database with a minimal amount of code using built-in input field types. Leveraging the power of Moose, HTML::FormHandler allows more complicated forms to override some or all of the built-in functionality while maintaining a common interface.</p><p>This meeting will take place on Tuesday, April 27rd at 7pm at Six Apart World Headquarters.</p><p>HTML::FormHandler on CPAN:<br>http://search.cpan.org/dist/HTML-FormHandler/</p><p>Announcement posted via App::PM::Announce</p><p>RSVP at Meetup - <a href="http://www.meetup.com/San-Francisco-Perl-Mongers/calendar/13059396/">http://www.meetup.com/San-Francisco-Perl-Mongers/calendar/13059396/</a></p> Phred 2010-04-01T17:21:36+00:00 journal svn to mercurial? http://use.perl.org/~nicholas/journal/40285?from=rss <p>Dear lazyweb...</p><p>We're using Trac at work.
