Jonathan writes: My performance work in October focused for the most part on escape analysis and scalar replacement. This work remains in a branch, however it has now reached the milestone of performing its first couple of real-world optimizations, eliminating short-lived boxes and wrapper objects across inline boundaries. I also started with some long-planned work on more aggressive optimization of lexical variables, such that they are stored as "locals" where

Jonathan writes: My main deliverable in September was a significant improvement to the performance of object construction and initialization. I wrote a blog post describing the ways in which this was achieved. I also improved the performance of array assignment, took on a tricky bug that stood in the way of merging a GC performance improvement, and took another small step with the work on escape analysis. 5:33 Lots of

My grant work in August focused on improving the performance of a number of very commonly used constructs in Perl 6 programs, of note array and hash access, box/unbox operations and various common operations on Int My work also uncovered a problem that could be best addressed with a small language design tweak, and I wrote up a proposal on that I also made various improvements to the optimization infrastructure.

Work in the latter part of July, falling under the current round of the grant, focused mostly on hunting down and fixing bugs. A memory leak bug involving the thread pool scheduler was fixed; it was only problematic in some programs so far, but would have become far more noticeable with the new 6.d await semantics. Others fixes addressed regressions arising from recent optimization work, although in most cases the

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. I didn't spend all that many hours during August on perl work. I spent most of my time looking at a bug related to restoring of captures within regex repeats. During the course of that, I took the opportunity to simplify and cleanup

As I announced at The Perl Conference in Salt Lake City this year, we have completed our project to update the main Perl Foundation website. The new site is now live, with a new design and on a new hosting platform. This project was primarily done by a team of Niagara University students as part of their CIS 480 coursework. This senior level class requires the students to work in
