JJ has made impressive progress on the backlog of documentation issues as part of his grant. He has already addressed and closed twice as many issues as all those closed by others. In doing so, he has committed about as many times as all other contributors to the repo.

While addressing issues, JJ performed some additional housecleaning and put in some quality time at StackOverflow.

You can read all the details in his blog for April.

March 2018 Grant Votes

No Comments

The Grants Committee has concluded the voting of the March 2018 round.

There was one proposal this round:

Follows the report by Chad Granum (aka EXODIST) for his grant: Test2 Manual.

Test2 Manual grant complete

This is a completion report for the Test2 manual grant.

Deliverables

  • Test2::Manual

    Original description:

    A brief introduction and table of contents.
    

    Completed form:

    Jumping off point with a map of the manual layout/table of contents.
    
  • Test2::Manual::Tooling

    Original description:

    This section will cover writing test tools. This would be a root document
    with several other page links.
    

    Complete form:

    The tooling page is the portal to all tooling tutorials. This section
    covers writing test tools.
    
  • Test2::Manual::Maintenance / Test2::Manual::Anatomy

    Original Description:

    This section will cover maintaining Test2 itself. This will be a root
    document pointing to pages that explain the internals, and how they work
    together.
    

    Final Form:

    I renamed this section to Test2::Tools::Anatomy. This section covers docs
    about Test2 internals and implementation details. This section is more
    complete and useful than I originally intended.
    

Completeness Criteria

Original criteria section from my proposal:

The manual will be included in a Test2 release on cpan. The manual will
have all expected sections, with no significant gaps or TODO sections.

Test2::Manual, with all the specified sections is now included in the Test2-Suite distribution on cpan. There are no TODO's or gaps in the sections that were part of my proposal, though there are TODO's in a third section that went beyond the scope of my grant.

The version with the complete manual is Test2-Suite-0.000114.

Bonus Material

I went beyond the scope of my original grant report and added the Test2::Manual::Testing section. This section is still incomplete, but was not part of my original grant proposal anyway, as such all the content that is complete is a nice bonus.

I also added the Test2::Manual::Concurrency and Test2::Manual::Contributing pages.

Revisiting the inch-stones

  • Migrating from Test::Builder

    Original:

    Conversion notes and examples for people moving from Test::Builder. This
    will detail how tools might have changed, what is gone, and introduce some
    new or replacement concepts.
    

    This is done as Test2::Manual::Tooling::TestBuilder.

  • Simple OK tool

    Original:

    This is the most basic tool you can write, and is valuable for explaining
    the key concepts universal to all Test2 tools.
    

    This section is complete, Test2::Manual::Tooling::FirstTool.

  • The Test2 API

    Original:

    This covers Test2::API, and all the functionality it exposes.
    

    This was not done as a single section. Instead there are handful of tutorials which show how to use some of the most common API functions.

  • The 'Context' object

    Original:

    Explain what the context object is, why it is important, and how to use it
    effectively.
    

    This did not need its own section. The Test2::Manual::Tooling::FirstTool covers all the important points about the context object from a tool writers perspective. Everything else is covered by the Test2::Manual::Anatomy::Context document.

  • The 'Hub' object and API

    Original:

    Explanation of the hub objects and how they work.
    

    This section is not necessary. Tool developers no longer need to directly interact with hubs. The things that would have been covered here are now part of the context and API pages.

  • Custom Hubs

    Original:

    How to write a hub subclass (essential for Subtest like tools).
    

    I decided not to write this section. A custom hub should rarely if ever be needed from the perspective of someone writing a new tool. The Test2::Manual::Tooling::Subtests covers the documentation I was going to write related to subtest like tools.

  • Custom event types

    Original:

    How to write an event.
    

    The event API underwent a major rewrite since my grant proposal, custom event types are now discouraged, as such this is not a necessary section.

  • Custom output formatters

    Original:

    How to write an output formatter.
    

    This section was completed as Test2::Manual::Tooling::Formatter.

  • Writing IPC drivers

    Original:

    How to write a custom IPC Driver.
    

    This section is not necessary, writing a custom IPC driver is not something to undertake lightly, and is not something a normal tool author needs to know about.

  • Component map

    Original:

    Map of all Test2 components.
    

    This is complete as Test2::Manual::Anatomy::EndToEnd. This is a more useful page than the originally specified one would ahve been.

  • Basic building blocks

    Original:

    Explanation of low-level infrastructure such as Test2::Util::HashBase.
    

    There is no building blocks page, instead there are pages for specific building blocks.

  • How the 'Context' works

    Original:

    Detailed overview of the Context object, and implementation details.
    

    This was done as Test2::Manual::Anatomy::Context.

  • The hub stack

    Original:

    What the hub stack is, and why it is important.
    

    This is done as Test2::Manual::Anatomy::Hubs.

  • The IPC system internals

    Original:

    How IPC works, and more importantly how it can fail.
    

    This is complete as Test2::Manual::Anatomy::IPC, except the failures of the IPC system have been reduced and handled better making the "how it can fail" component unnecessary.

  • Utilities

    Original:

    The utilities library, and important implementation details.
    

    Done as Test2::Manual::Anatomy::Utilities.

  • Performance Notes

    Test2 is now faster than Test::Builder making this section unnecessary.

Grant Report : Complete YAML::PP - March 2018

No Comments

Tinita spent about 25 hours coding YAML::PP during March.

She emitted a production release at YAML::PP 0.006, which incorporates items from her previous reports, adding Writer and Representer objects, a nice Dumper, and cyclic reference detection.

In a spirit of multi-cultural outreach and understanding, she also made her first PR to PyYAML.

You can read all the details in her latest report.

Perl 6: Bugfixing and Performance of Rationals

Fixing Constraints on Constants

  • Name:

    Zoffix Znet

  • Amount Requested:

    USD 1,999

Synopsis

The proposal is to perform two pieces of work on the Rakudo Perl 6 compiler along with a third bonus piece:

    1. Implement support for type constraints on constants and polish some of the rough edges with = and .= constants initializer calls.
    1. Fix several bugs and a race condition as well as fix problems in edge cases in instantiation and literals in core Rational types, also try to improve performance in this area.
    1. BONUS Work: Fix bugs in native uint64 attributes behaving like signed int64 types and try to use these attributes to boost performance of Rat type.
