NAME

Ecosystem::Archive::Update - Updating the Raku Ecosystem Archive

SYNOPSIS

use Ecosystem::Archive::Update;

my $ea = Ecosystem::Archive::Update.new(
  shelves     => 'archive',
  jsons       => 'meta',
);

say "Archive has $ea.meta.elems() identities:";
.say for $ea.meta.keys.sort;

DESCRIPTION

Ecosystem::Archive::Update provides the basic logic to updating the Raku Ecosystem Archive, a place where (almost) every distribution ever available in the Raku Ecosystem, can be obtained even after it has been removed (specifically in the case of the old ecosystem master list and the distributions kept on CPAN).

ARGUMENTS

shelves

The name (or an IO object) of a directory in which to place distributions. This is usually a symlink to the "archive" directory of the actual Raku Ecosystem Archive repository. The default is 'archive', aka the 'archive' subdirectory from the current directory.

jsons

The name (or an IO object) of a directory in which to store META6.json files as downloaded. This is usually a symlink to the "meta" directory of the actual Raku Ecosystem Archive repository. The default is 'meta', aka the 'meta' subdirectory from the current directory.

degree

The number of CPU cores that may be used for parallel processing. Defaults to the half number of Kernel.cpu-cores.

batch

The number of objects to be processed in parallel per batch. Defaults to 64.

METHODS

batch

say "Processing with batches of $ea.batch() objects in parallel";

The number of objects per batch that will be used in parallel processing.

clear-notes

my @cleared = $ea.clear-notes;
say "All notes have been cleared";

Returns the notes of the object as a List, and removes them from the object.

degree

say "Using $ea.degree() CPUs";

The number of CPU cores that will be used in parallel processing.

investigate-repo

my @found = $ea.investigate-repo($url, "lizmat");

Performs a git clone on the given URL, scans the repo for changes in the META6.json file that would change the version, and downloads and saves a tar-file of the repository (and the associated META information in git-meta) at that state of the repository.

The second positional parameter indicates the default auth value to be applied to any JSON information, if no auth value is found or it is invalid.

Only Github and Gitlab URLs are currently supported.

Returns a list of Pairs of the distributions that were added, with the identity as the key, and the META information hash as the value.

Updates the .meta information in a thread-safe manner.

jsons

indir $ea.jsons, {
    my $jsons = (shell 'ls */*', :out).out.lines.elems;
    say "$jsons different distributions";
}

The IO object of the directory in which the JSON meta files are being stored. For instance the IRC::Client distribution:

meta
  |- ...
  |- I
     |- ...
     |- IRC::Client
         |- IRC::Client:ver<1.001001>:auth<github:zoffixznet>.json
         |- IRC::Client:ver<1.002001>:auth<github:zoffixznet>.json
         |- ...
         |- IRC::Client:ver<3.007010>:auth<github:zoffixznet>.json
         |- IRC::Client:ver<3.007011>:auth<cpan:ELIZABETH>.json
         |- IRC::Client:ver<3.009990>:auth<cpan:ELIZABETH>.json
     |- ...
  |- ...

identities

say "Archive has $ea.identities.elems() identities, they are:";
.say for $ea.identities.keys.sort;

Returns a hash of all of the META information of all distributions, keyed by identity (for example "Module::Name:ver<0.1>:authfoo:bar:api<1>"). The value is a hash obtained from the distribution's meta data.

meta-as-json

say $ea.meta-as-json;  # at least 3MB of text

Returns the JSON of all the currently known meta-information. The JSON is ordered by identity in the top level array.

note

$ea.note("something's wrong");

Add a note to the notes of the object.

notes

say "Found $ea.notes.elems() notes:";
.say for $ea.notes;

Returns the notes of the object as a List.

shelves

indir $ea.shelves, {
    my $distro-names = (shell 'ls */*/*', :out).out.lines.elems;
    say "$distro-names different distributions in archive";
}

The IO object of the directory where distributions are being stored in a subdirectory by the name of the module in the distribution. For instance the silently distribution:

archive
 |- ...
 |- S
    |- ...
    |- silently
        |- silently:ver<0.0.1>:auth<cpan:ELIZABETH>.tar.gz
        |- silently:ver<0.0.2>:auth<cpan:ELIZABETH>.tar.gz
        |- silently:ver<0.0.3>:auth<cpan:ELIZABETH>.tar.gz
        |- silently:ver<0.0.4>:auth<zef:lizmat>.tar.gz
    |- ...
 |- ...

Note that a subdirectory will contain all distributions of the name, regardless of version, authority or API value.

update

my %updated = $ea.update;

Updates all the meta-information and downloads any new distributions. Returns a hash with the identities and the meta info of any distributions that were not seen before. Also updates the .identities information in a thread-safe manner.
