  1. Perl Toolchain Summit (formerly known as Perl QA Hackathon) 2019

    Sponsors Booking.com, cPanel, MaxMind, FastMail, ZipRecruiter, Cogendo, Elastic, OpenCage Data, Perl Services, Zoopla, Archer Education, OpusVL, Oetiker+Partner, SureVoIP, YEF
  2. • The Perl programming Authors Upload SErver • The back

    stage entrance to the CPAN • Written by Andreas König in 1995 • Generates indices of authors/packages What's PAUSE?
  3. • Its UI was (last) overhauled in 1999 • It

    may look old-fashioned compared with other portals including MetaCPAN or modules.perl6.org • Things around us has been changing PAUSE has been serving us well for a long time
  4. 0 500 1000 1500 2000 2007 2008 2009 2010 2011

    2012 2013 2014 2015 2016 2017 2018 2019 Active authors Authors with new releases PAUSE itself can't stop our downtrend 0 200 400 600 800 1000 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 New authors New active authors
  5. Maybe we can help a little • to make it

    easier to transfer abandoned modules to someone • to show beginners how to make a release (PAUSE has some under "About PAUSE" section)
  6. Growing pains • PAUSE used to list everything on a

    single page • This may not have been a problem before • Too many checkboxes for some authors (150 authors have or had 50+ distributions, and 50+ authors have or had 100+ dists now)
  7. External PAUSE Tools but shouldn't it be better to fix

    PAUSE? (plus a few uploaders and scripts, etc) App::pause PERLANCAR App::PAUSE::CheckPerms NEILB App::PAUSE::cleanup YANICK App::PAUSE::Comaint MIYAGAWA Pcore::API::PAUSE ZDM WWW::PAUSE::CleanUpHomeDir ZOFFIX WWW::PAUSE::Simple PERLANCAR
  8. PAUSE on Plack (2015~16) • Replaced mod_perl/Apache with Plack/Starman (2015)

    • Went into production (2016) • Occasional stability issue(s) (~2019?)
  9. PAUSE on Mojolicious (2017~19) • Big rewrite for templates and

    plugins (2017) • Went into produciton from my mojo_wip branch (2018) • Fell back to PAUSE on Plack sometimes (2018) • Merged into master (2019)
  10. Markdown rendering (2018) • Made it easier to add new

    documents • PAUSE Operating Model • Privacy Policy • More to come
  11. From XHTML to HTML5 (2018) • No more table layout

    • Min.css just for grid layout • Not optimized yet New UI mockup by Babs Veloso (Not implemented yet)
  12. How many items in a page? • 100 items per

    page was too small for Mojolicious, DBIx::Class etc. • Increased to 300 for the time being • How can we help distributions with thousands of modules?
  13. No more partial transfer Filtering by "Starman" module was not

    enough because Starman contains a module under a different namespace (HTTP::Server::PSGI::Net::Server::PreFork)
  14. Incomplete ownership • Distributions may be owned by multiple owners

    (because a new contributor releases a new module without specifying x-authority, or because of partial transfer) • If you want to be a new contributor, you (usually) need to ask all of the owners for permission
  15. "Permission manager" permission • Formerly known as "Admin" permission •

    To let someone grant permissions to someone else without giving up your owner rights • Permission manager needs to know new modules added by others, but how? • Discussed but not implemented yet
  16. reCAPTCHA (2018) • ID requests used to be approved by

    the PAUSE admins, but this process takes time • 25% of new users release their first distribution on the day of approval • David Golden introduced reCAPTCHA to eliminate this delay and admins' burden
  17. Exposed user status (2019) • For other CPAN services to

    remove/hide spammers' information • We may need "system" status as well for special users (ADOPTME etc)
  18. GDPR: Right to be forgotten • You can't delete your

    account if you have uploaded something • You can empty most of your personal data by yourself • We started hiding data of deleted accounts (2019) • More to come
  19. OAuth2 as authorization • Lee Johnson made a branch for

    this • For ACT users to allow ACT to use their personal data • ... but almost everything is exposed via indices now • Providing official API would be nice • (Ab)use for user verification for RT/MetaCPAN?
  20. Multi-factor Auth • Recent account hijackings for other portals (rubygems,

    npm) • Not implemented yet but we should • As long as other CPAN clients/services support this • https://github.com/andk/pause/issues/292
  21. Perl6 indices • Actually there are two indices (+ empty

    one) for Perl 6 • modules.perl6.org is making its own indices # CPAN/authors/p6dists.json.gz { "A/AK/AKIYM/Perl6/JSON-Hjson-0.0.1.tar.gz" : { "name" : "JSON::Hjson", "auth" : "AKIYM", "ver" : "0.0.1" }, ... } # CPAN/authors/p6provides.json.gz { "Math::Random" : [ "P/PS/PSIXDISTS/Perl6/Math-Random-0.000.001.tar.gz" ], "Math::FFT::Libfftw3::Exception" : [ "F/FR/FRITH/Perl6/Math-FFT-Libfftw3-0.1.1.tar.gz", "F/FR/FRITH/Perl6/Math-FFT-Libfftw3-0.1.2.tar.gz", "F/FR/FRITH/Perl6/Math-FFT-Libfftw3-0.1.3.tar.gz" ], ... }
  22. Transferring Perl6 modules • Currently there's no permission management for

    Perl6 modules • Just author(s), instead of P5's first-come + contributors? • ADOPTME/HANDOFF/NEEDHELP/NOXFER?
  23. Other changes • Ricardo Signes and Neil Bowers finished their

    efforts to make PAUSE indices case insensitive • Slaven Reziç fixed pause.cpan.org certification issue • Abandon primary permissions now means transfer to ADOPTME • Various test/logging improvements • Burp reports by Lee Johnson
