The Perl Conference May Newsletter

This is a monthly report by Dave Mitchell on his grant under Perl 5 Core Maintenance Fund. We thank the TPF sponsors to make this grant possible.


The main thing I have been doing over the last month is continuing to fix
issues related to smoke reports and getting blead in shape for the 5.30.0
release. In particular, I've been looking at Address Sanitizer failures
related to memory leaks.

March saw me spending rather little time on my Perl 6 grant. I merged various optimizations I developed during February, but held back to merge until after the March release in order that they could receive more testing before appearing in a release. I also did a few other minor optimizations, and fixed a performance regression introduced during a recent bug fix.

During March, I attended the German Perl Workshop. My talks included one on escape analysis, which I have been working on as part of this grant.

1:08 Test, re-benchmark, and merge optimizations developed
     in the previous month
1:41 Investigate a performance regression arising from a
     BEGIN-time compilation bug fix, modify the fix
     accordingly
0:44 Analyze an increase in malloc/free churn during
     specialization code generation and avoid it
0:33 Shave a few more cycles off scalar dereferences
0:50 Issue and pull request triage

Google Summer of Code is making great progress. I appreciate everyone's help so far.

Separately, The Perl Foundation plans to participate in the first edition of Google Season of Docs. This initiative will fund writers to help improve the documentation of open source projects, and TPF will be applying to improve the documentation of the Perl 6 language. This documentation effort started in 2012 and is fully volunteer based. It's mostly complete and has proven to be helpful for new users, but it has got two main issues: getting updated for the 6.d release (November 2018) and tackle some gaps in the documentation of exceptions and precompilation.

TPF welcomes contributions to the documentation as well as all its other projects, inside or outside the Season of Docs.

If you are interested in participating as a writer or proposing new project ideas, check the season of docs site as well as Perl 6 documentation ideas site. Feel free to get in touch with JJ Merelo for questions.

20th Year Anniversary Planning Lead
We're looking for volunteers who can help make the significance of the 20th Anniversary of Perl conferences stand-out! You don't need to have event planning experience to help out, but it is a plus if you have attended past Perl conferences. The Planning Lead will get to see their vision become a reality at #TPCiP and they'll get free admission to the event's main conference days!

Bart received helpful comments on his blog posts last month that will move him ahead with intermediate representation (IR) optimization and register allocation.

He writes:

I'm still working on finalizing the floating point support for the JIT compiler, but I've also started work on the new register allocation algorithm. This wasn't strictly a deliverable, but I expect it will help the deliverable of improving code generation.
