NAME

Perl::Build::Git - Convenience extensions for Perl::Build for bulk git work

VERSION

version 0.001000

SYNOPSIS

This is something that might be useful to call in a git bisect runner

use Perl::Build::Git;
my $man         = [qw( man1dir man3dir siteman1dir siteman3dir  )];
my $no_man_opts = [ map { '-D' . $_ . '=none' } @{$man} ];
my $install = Perl::Build::Git->install_git(
        persistent => 1,
        preclean   => 1,
        cache_root => '/tmp/perls/',
        git_root   => '/path/to/git/checkout',
        configure_options => [
            '-de',               # quiet automatic
            '-Dusedevel',        # "yes, ok, its a development version"
            @{$no_man_opts},     # man pages are ugly
            '-U versiononly',    # use bin/perl, not bin/perl5.17.1
        ],
);
$install->run_env(sub{
        # Test Case Here
        exit 255 if $failed;
});
exit 0;

persistent = 1 is intended to give each build its own unique directory, such as

/tmp/perls/v5.17.10-44-g97927b0/

So that if you do multiple bisects, ( for the purpose of testing which incarnation of perl some module fails in ), testing against a perl that was previously tested against in a previous bisect should return a cached result, greatly speeding up the bisect ( at the expense of disk space ).

METHODS

install_git

Perl::Build::Git->install_git(
    cache_root => '/some/path',
    git_root   => '/some/path/to/perl/git',
    persistent => bool,
    preclean   => bool,
    quiet      => bool,
    log_output => filehandle,
    log        => coderef,
);

• cache_root

  path. This should be a path to an existent base working directory to install multiple perl installs to

  Perl builds will either be in the form of

  <cacheroot>/<tag>-g<sha1abbrev>

  or

  <cacheroot>/<tag>-g<sha1abbrev>-<SUFFIX>

  depending on persistent

• git_root

  path.

  This should be a path to an existing perl git checkout.

• persistent

  bool.

  Whether to make the build directory persistent or not. Persistent directories can be optimistically re-used, while non-persistent ones can not.

  Non Persistent directories also have a random component added to their path, and implied cleanup on exit.

  Default is NOT PERSISTENT

• preclean

  bool.

  Whether to execute a pre-build cleanup of the git working directory.

  This at present executes a mash of git checkout, git reset and git clean.

  Default is PRE-CLEAN GIT TREE

• quiet

  bool.

  If specified, the default method for log is a no-op.

  The default is NOT QUIET

• log_output

  filehandle.

  Destination to write log messages to.

  Default is *STDERR

• log

  coderef. Handles dispatch from logging mechanisms, in the form

  $logger->( $color_spec , @message );

  where color_spec is anything that Term::ANSIColor::colored understands.

  $logger->( ['red'], "this", "is", "a" , "test" );

  Default implementation writes to log_output formatting @message via Term::ANSIColor.
