I spent last month mainly working on "fuzzer" bug reports, and trying to process some of the backlog in my p5p mailbox.

As of 2016/07/31: since the beginning of the grant:

146.0 weeks
1988.7 total hours
13.6 average hours per week

There are 411 hours left on the grant (it having just been extended by 400 hours).

I am pleased to report that Dave Mitchell's recent request to extend his Maintaining the Perl 5 Core grant has been successful. The award of $20,000 will allow him to spend another 400 hours on this project.

Thanks to everyone who provided feedback on this application and to all those who continue to provide financial support to the Perl 5 Core Maintenance Fund. If you are interested in funding this work please contact karen [at] perlfoundation.org.

Will reports on the completion of Chapter 2 of Learning RPerl:

"Initial work on chapter 2 of Learning RPerl is finally finished! Hopefully chapters 3 and 4 will not take quite so long to complete. :-)

All of the following sections have now been published:

Chad has been working slowly on his grant given some personal issues. Nevertheless, there is some progress on Test2-Manual, namely some formatting issues. You can peek Chad work on his GitHub repository, https://github.com/Test-More/Test2-Manual. Be sure to look both to the master and gh-pages branches, as neither gives a complete view of Chad plans in isolation.

I didn't really do much that stands this month; I just reduced the backlog in my p5p mailbox a bit, and worked on several miscellaneous tickets.

The most noteworthy bugfix related to $@ getting overwritten while exiting an eval scope. Earlier work by Zefram had ensured that $@ is assigned to in a late stage of scope unwinding, but it turns out that in void context or after a die, the temps stack was still being freed after $@ had been assigned to, which could result in destructors being called that could overwrite $@. (My work last year on the context stack meant that this had already been fixed for scalar and list context evals). For example:

sub DESTROY { $@ = "spurious\n" }
eval  { die ((bless []) ?  "foo" : "bar") };
print $@; # prints "spurious" rather than "foo"

I did some refactoring of the eval code and then provided a fix, but this broke a Variable::Magic test and has been temporarily reverted.

Will Braswell provides this update:

"RPerl v2.0 has been officially released, including the long-awaited automatic parallelization feature, which pushes us beyond the everyday speed of serial C++ to the bleeding-edge speed of parallel C++.

Accordingly, the following Learning RPerl sections have been added or updated:
