THREE new perl releases

    Today, three new perl versions have been released:

    The main reason is two fixed CVE's:

    • CVE-2023-47038 - Write past buffer end via illegal user-defined Unicode property
    • CVE-2023-47039 - Perl for Windows binary hijacking vulnerability

    CVE-2023-47038 is only relevant during the use of \p in regexes. This is only a problem if you accept regular expressions from untrusted sources.

    Enjoy, Have FUN! H.Merijn

    After a long time of work, the videos are finally available on Youtube. 20 presentations with a total of 14 hours of airtime review the three days of the workshop and you can watch the things you missed on site.

    We would especially like to thank Lee Johnson, who made the recordings, and the presenters, of course, without whom the workshop would not have taken place. The support from our sponsors helps us make the workshop take place.

    The recordings of the German Perl Workshop 2023 are organised in the order of the day in a playlist available at gpw2023.

    We are planning the German Perl Workshop 2024 again and are already in the final negotiations. As soon as we have a place and date fixed, we will update this post and also make a separate announcement.

berrybrew version 1.40 released

    I have released version 1.40 of berrybrew. It comes with some extensive changes over this, and the previous 1.39 version. (See the changes list).

    User facing changes include:

    • Ability to install and use the new 5.36 and 5.38 releases of Strawberry Perl
    • berrybrew archives hidden command. It displays the list of portable Strawberry Perl zip files previously downloaded
    • berrybrew download hidden command. Download, but do not extract the zip archive of a perl version
    • berrybrew snapshot command. Export an installed perl version to a zip archive, and import a previous zip snapshot to a new installed instance

    berrybrew snapshot usage:

    • bb snapshot export <perl version> [snapshot name]
    • bb snapshot import <snapshot name> [new instance name]

    As far as changes on the developer side, the changes are significant. Here's a high-level list:

    • Broke out like functionality in the main berrybrew.cs source file, and spread it across several new classes, each in their own source file
    • Removed the deprecated berrybrew upgrade command. Upgrades shall be done via the installer
    • Created a very extensive MANIFEST checking system for the installer. This ensures that all files that need to be installed are, those same files are removed upon uninstall, and no rogue files when building the installer are accidentally leaked in
    • Added a significant amount of documentation for the development, build, test and release lifecycle of the project. If I get hit by a bus, I've created a fantastic roadmap for someone to carry on the project quite readily (bb dev docs)
    • A few minor bug fixes, and one major one

berrybrew can now use 5.36 and 5.38

    Update: The most recent release of berrybrew now includes the 5.36 and 5.38 version information, so no change of options are required to use them. As always, you can if you like review the Changes log to see what else has changed.

    I forked the Strawberry Perl repo and updated the releases.json file, which berrybrew uses to know what perls are available.

    One small gotcha... normally it gets this file from Strawberry Perl website, but nobody currently has access to manage it. I've created a PR to get the releases.json updated, but until the PR is merged, we can use my forked version (I will update this thread with what will become the official URL after the PR is merged. After the Strawberry site is back to being actively maintained, the temporary link can be removed, but will going forward remain valid).

    To use the new perls, we have to update a berrybrew option that specifies where we get our version information:

    berrybrew options download_url +eb9/

    Then fetch the new versions:

    berrybrew fetch

    Now they're available:

    berrybrew available

    Here's the entire operation:

    > berrybrew options download_url +vieb9/ download_url: > berrybrew fetch Attempting to fetch the updated Perls list... Successfully updated the available Perls list... > berrybrew available The following Strawberry Perls are available: 5.38.0_64 5.38.0_64_PDL 5.36.1_64 5.36.1_64_PDL 5.32.1_64 5.32.1_64_PDL 5.32.1_32 … > berrybrew install 5.38.0 Downloading +eases/download/SP_5380_5361/strawberry-perl- +ip to C:\berrybrew\temp\ Confirming checksum ...

    Just a PSA that the domain has not been renewed and its registrant is sadly still out of contact. I have an option on the domain which will allow me to take ownership in a month, but until then (or the domain is renewed) it will not function.

    Howdy! We have a full three day conference planned in Toronto, running July 11-13 -- that's just 4 1/2 weeks away!

    If you haven't registered and grabbed a room yet, this is a reminder that our room block will disappear on Monday, June 19, so be sure to grab the room you want before that date.

    In addition to the conference, there's going to be a hackathon on Monday, July 10, and Dave Rolsky will be putting on a one-day Go class on Friday July 14. That's all taking place at the venue, the Doubletree Hilton on Chestnut, in downtown Toronto. Please visit the conference website for more information, and I hope to see LOTS of you there!

    Alex / talexb / Toronto

    Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.

Raku is one of the few newbies in the top 100

    "The only languages younger than 10 years in the current top 100 are: Swift (#14), Rust (#17), Crystal (#48), Solidity (#59), Pony (#71), Raku (#72), Zig (#88) and Hack (#92). None of them are less than 5 years old. In other words, it is almost impossible to hit the charts as a newbie. On the contrary, we see that golden oldies revive. Take for instance Fortran, which is back in the top 20 thanks to the growing demand for numerical computational power. So, if you have just invented a brand new language, please have some patience!" -- Paul Jansen CEO TIOBE Software

    PDL 2.082_01 has just been released. Notable changes since 2.082:
    • fix some memory leaking - thanks Yury Pakhomov for report
    • fix various problems with empty ndarrays - thanks @falsifian for report/tests
    • no more HTML doc generation
    • PDL::Doc::add_module now adds all submodules of given namespace (#420)
    • OtherPars can now be incomplete arrays of pdl* (#421)
    • add sound demo - thanks @HaraldJoerg
    • inplace operations no longer copy input arg if inplace

    The IRC channel (#pdl on is a great virtual place to come and ask questions, or just watch the GitHub messages flow by.

    Please give the new release a try and report problems.

    The Strawberry Perl project has put out a developer pre-release of Strawberry Perl. There are some modules missing still (DBD::Oracle, PDL, Crypt::OpenSSL::DSA for example), but if you use Strawberry Perl, please test it and provide feedback via Github.

    If you can help with the open tickets, your help getting the modules included in Strawbery Perl is certainly appreciated.

Release: JSON::SIMD 1.05

    A new release of the previously announced JSON::SIMD. Changes:
    • fix build issue with "invalid register for .seh_savexmm"
    • add ppport.h
    • add core_bools and encode_core_bools methods to support builtin::true and false on perl >= 5.36

      core_bools also works towards compatibility with JSON::PP, and with both of these options it is possible to have correct, full round-trip encode/decode between Perl and JSON booleans.

    • fix floating point precision issues with -Duselongdouble and -Dusequadmath
    • fix intermittent garbage in floating point numbers from encode with -Dusequadmath (fix taken from Cpanel::JSON::XS ad072b4)
    • drop common::sense as a direct dependency (it's still used indirectly via Types::Serialiser, though)
    • fix repository and issue tracker for CPAN (thanks to Gabor Szabo)

    Those who previously reported build failures, could you please retest?

    I'd also be interested in benchmarks on various configurations. The distribution now includes a in the eg directory, just run it with as many JSON files as you'd like. If you report benchmark results, please include the CPU type and the output of JSON::SIMD::simdjson_version as well.

    With this version, I think I've added everything I've wanted. In the future I'll intend to track new releases from both JSON::XS and simdjson, and of course I'd fix any reported bugs ASAP. (There is one major new feature I'm thinking about, the ability to have partial/deferred decodes and precomputed encodes similar to Go's json.RawMessage, but I don't have a clean and safe design for it yet, so it'll have to wait. I don't want to add ad-hoc features haphazardly.)
