Details

We approve this grant.

This is an area that needs work in Rakudo Perl 6, and Zoffix has a history of delivering tangible improvements to the compiler and the infrastructure in the community.

Our next round will be in March. You can submit proposals now. If you want to help funding, one of the options is Amazon Smile. We appreciate all the donors which made the grant program possible. Also see the press releases for the recent major donations.

Dave Mitchell recently requested an extension of his Maintaining Perl 5 grant.

I'm pleased to announce that the Board of Directors approved extension of another $20,000.

MAJ

The Grants Committee has received one grant proposal Standardization, Test Coverage, and Documentation of Perl 6 I/O Routines for the January round. Before the Committee members vote, we would like to solicit feedback from the Perl community on the proposal.

Review the proposal below and please comment here by January 23rd, 2017. The Committee members will start the voting process following that and the conclusion will be announced approximately in one week.

Standardization, Test Coverage, and Documentation of Perl 6 I/O Routines

  • Name:

    Zoffix Znet (legal name: Pete Evstratov)

  • Amount Requested:

    USD 999

Synopsis

Many of Perl 6's I/O routines currently have inconsistencies in behaviour between method and subroutine forms along with inconsistencies in calling forms and failure modes compared to the rest of the language. Also some of them, despite being speculated in the synopses and implemented in Rakudo, have no test coverage in the Perl 6 Specification, and as such they remain undocumented and not part of the Perl 6 Language. Some of the routines that do have presence in the Specification, have sparse test coverage, leaving some of their functionality entirely untested.

The work funded by this grant seeks to resolve those inconsistencies, as well as provide full test coverage and documentation.

Benefits to the Perl Community

Inconsistent interfaces are difficult to master and are bug-prone due to programmers forgetting about varying details of individual routines. By making I/O routines take arguments and indicate failures consistent to the way it's done in the rest of the language, they will be much easier for programmers to learn and use. Along with a more pleasant interface, the Perl Community will also benefit by needing to provide less support for people trying to learn the language.

The largest benefit will come from the full test coverage that will no doubt reveal bugs that can be fixed before they're encountered by users in production code. The coverage will also protect from future bugs being introduced inadvertently. Also, the currently unspecced routines will be officially part of the language, and so will be documented and available for use.

As bonus benefits:

The timing of this work seeks to align with the production of "Learning Perl 6" book, in order for it to contain valid information on I/O routines and describe only routines that are actually part of the language, which will avoid confusion for its readers and folks helping those readers learn Perl 6.

Lastly, the bonus deliverables (described below) will benefit further development of Rakudo/Perl 6 by elucidating unspecced, unused, or unwanted routines. The data can also be used to produce a teaching/reference aid (e.g. flash cards with routine names or IRC bot for routine reference).

I spent December:

1) looking for quick some wins on speeding up perl compile-time, using
'perl -MCPAN -e1' as a typical example of loading and compiling several
.pm files.  I tweaked Perl_yyparse() and shaved ~2% off the compile time;
then tweaked Perl_sv_gets() and shaved another ~2% off, and also got a
pleasing run-time boost for line reading, with reading a big list of words
now ~8% faster on my system:

    perl -e'$i++ while (<>)' /usr/share/dict/words

2) investigating possible ways of making the regex engine faster by (in
some cases) processing 8 bytes at a time on 64-bit platforms. This
culminated in an this email thread:

    http://nntp.perl.org/group/perl.perl5.porters/241891

3) as usual, working on a few miscellaneous tickets.

Dave Mitchell has requested an extension of $20,000 for his Maintaining the Perl 5 Core grant. This will allow him to dedicate another 400 hours to this work. During this grant he sent regular reports to the p5p mailing list as well as providing monthly summary reports that have been published on this site, the most recent of which are linked below:

Before we make a decision on this extension, we would like to have a period of community consultation. Please leave feedback in the comments field below or if you prefer, send email with your comments to makoto at perlfoundation.org. We request that all the feedback should be sent by January 15th.

If successful this extension will be funded from the Perl 5 Core Maintenance Fund.

I spent last the last two months:

* reworking list assignment (especially with an aggregate on the LHS) to
  be much faster in many cases. For example, this code is 33% faster in
  5.25.7 compared with 5.24.0:

    my @a;
    for my $i (1..10_000_000) {
        @a = (1,2,3);
        @a = ();
    }

* trying to reduce the overhead of compile time a bit;

* freeing up some uses of SV flags;

* fixing various assorted bugs as listed below;

Grant Proposal: Learning Perl 6, a book from O'Reilly Media

At the invitation of the TPF board, brian has withdrawn the grant proposal for the Learning Perl 6 book, and will submit a proposal to TPF on other ways for TPF to participate in enhancing the visibility of Perl 6.

The Grants Committee had a general discussion on funding activities whose output is not free of charge. TPF has documentation that states grant results must be "released under a publically available license that is free for redistribution and use without discrimination against field of endeavour" (from the "Grant Benefits" page), but the process of reviewing this proposal revealed that the documentation was easy to miss and not clearly stated as policy in the Grants Committee rules of operation. The committee unanimously agreed to update the rules to make it clear that all grant results should be available free of charge. We are in the process of adding such a clause to the rules of operation soon (wording may be slightly changed):

1.3. Grant proposals should mention how the grant results will be made available to the public. The grant results must be must be accessible free of charge.

Chad Granun reports on his work on the Test2 Manual grant. The last month was devoted to:

  • How to list the test tools in the modules dependencies;
  • Tutorial for TODO tests;
  • Tutorial for advanced test planning.

The Grants Committee is accepting grant proposals all the time. We evaluate them every two months and another evaluation period has come.

If you have an idea for doing some Perl work that will benefit the Perl community, consider sending a grant application. The application deadline for this round is 23:59 January 15th UTC. We will publish the received applications, get community feedback and conclude acceptance by January 25th.

To apply, please read How to Write a Proposal. Rules of Operation and Running Grants List will also help you understand how the grant process works. We also got some grant ideas from the community. The format is the same as the previous rounds in 2014-2016.

We will confirm the receipt of application within 24 hours.

If you have further questions, please contact me at tpf-grants-secretary at perl-foundation.org.
