NAME

App::cpanm::meta::checker - Verify and sanity check your installation verses cpanm meta files

VERSION

version 0.001002

SYNOPSIS

cpanm-meta-checker --all --verbose

DESCRIPTION

cpanm installs a few auxiliary files:

$SITELIB/.meta/DISTNAME-DISTVERSION/MYMETA.json
$SITELIB/.meta/DISTNAME-DISTVERSION/install.json

These files describe several things, such as dependencies declared by upstream, and sniffed extra context.

This tool exists to read those files, and verify that their dependencies are still holding true, that no new conflicting dependencies have been installed and are silently sitting there broken.

Also, as cpanm's auxiliary files are really a prototype for what may eventually become a tool-chain standard, this tool is also a prototype for a tool-chain standard checker.

METHODS

all_search_dirs

my @dirs =  $checker->all_search_dirs

See "search_dirs"

all_search_dir_child

my @items = $checker->all_search_dir_child( 'some','path' );

Returns all paths in all search_dirs that exist with the given name.

search_dirs = [ 'foo', 'bar' ]
all_search_dir_child('baz')
  → foo/baz → exists(Y) → output
  → bar/baz → exists(N) → omitted

all_search_dir_children

my @items = $checker->all_search_dir_children();

Returns all child nodes of all search_dirs

search_dirs = ['foo','bar' ]
all_search_dir_children()
  → (
      path( 'foo' )->children,
      path( 'bar' )->children,
    )

check_path

->check_path('./foo/bar/baz');

Read the content from ./foo/bar/baz and check its consistency.

check_release

->check_release('Moose-2.000000')

Read the meta-data for the exact release stated and perform checks on it.

check_distname

->check_distname('Moose')

Check meta-data for any dist(s) named Moose

Note: There may be directories residual from past installs.

check_all

->check_all

Check meta-data for all installed distributions.

run_command

$checker->run_command;

Execute test mode defined by mode

new_from_command

This is the command interface invoked by cpan-meta-checker that cherry picks options with Getopt.

my $instance = App::cpanm::meta::checker->new(
  %constructor_defaults
);

This creates an instance where %constructor_defaults are overridden by relevant command line arguments.

Command Line Arguments

  • -s|--sort - Process dist directories in alphanumeric order.

  • -A|--all - Check All distributions on the system

  • --verbose - Turn on extra verbosity

    This presently just prepends the list test to the test list.

  • --test foo - Test only test foo

    May be invoked multiple times to define all tests wanted.

    --test check_develop_requires --test check_runtime_suggests

ATTRIBUTES

search_dirs

tests

The tests to execute.

Default:

[
  'list_empty',               'list_duplicates',        'check_runtime_requires',
  'check_runtime_recommends', 'check_runtime_suggests', 'check_runtime_conflicts',
];

sorted

Iteration order of .meta directory.

false - not sorted
true - alphanumerically sorted

mode

Defines execution mode:

all - Perform tests on all available distributions

DEFAULT TEST SET

list_empty
list_duplicates
check_runtime_requires
check_runtime_recommends
check_runtime_suggests
check_runtime_conflicts

AVAILABLE TEST SET

list_duplicates

For now, it includes output about every instance where there are more than one set of meta files.

This occurs, because installing a new version of something doesn't purge the data ( or all the files ) of the old one.

list

This lists all distributions seen.

list_empty

This lists distributions that have a directory for a meta file, but have no meta file in them. ( Rare )

list_nonempty

This lists distributions that have meta files.

check_PHASE_TYPE

There is a check for each combination of:

PHASE: configure build runtime test develop
TYPE:  requires recommends suggests conflicts

Each checks the meta-data for conforming dependencies.

For instance:

check_runtime_requires # Report Runtime requirements that are unsatisfied
check_develop_requires # Report Develop requiremetns that are unsatisifed
