oracular (3) App::DocKnot::Dist.3pm.gz
NAME
App::DocKnot::Dist - Prepare a distribution tarball
SYNOPSIS
use App::DocKnot::Dist;
my $docknot = App::DocKnot::Dist->new({ distdir => '/path/to/dist' });
$docknot->make_distribution();
REQUIREMENTS
Git, Perl 5.24 or later, and the modules File::BaseDir, File::ShareDir, Git::Repository, IO::Compress::Xz
(part of IO-Compress-Lzma), IO::Uncompress::Gunzip (part of IO-Compress), IPC::Run, IPC::System::Simple,
Kwalify, List::SomeUtils, Path::Tiny, and YAML::XS, all of which are available from CPAN.
The tools to build whatever type of software distribution is being prepared are also required, since the
distribution is built and tested as part of preparing the tarball.
To sign distribution tarballs, the GnuPG command-line program gpg is required. (Any version, either
GnuPG v1 or GnuPG v2, should work.)
DESCRIPTION
This component of DocKnot generates distribution tarballs for a package. This is a bit of an odd
inclusion in the DocKnot suite, since it's not about generating documentation, but it uses the same
configuration and metadata as the rest of DocKnot.
Specifically, App::DocKnot::Dist exports the current branch from Git into a separate working directory,
runs the commands appropriate to create a distribution (based on the build system configured in the
package metadata), and cleans up the working directory.
CLASS METHODS
new(ARGS)
Create a new App::DocKnot::Dist object. This should be used for all subsequent actions. ARGS should
be a hash reference with one or more of the following keys:
distdir
The path to the directory into which to put the distribution tarball. This should point to a
trusted directory, not one where an attacker could have written files (see make_distribution()
below). Required if not set in the global configuration file.
gpg The path to the gpg binary, used to sign generated tarballs if "pgp_key" is present in the global
configuration or provided as a constructor argument. Default: The binary named "gpg" on the
user's PATH.
metadata
The path to the metadata for the package on which to operate. Default: docs/docknot.yaml
relative to the current directory.
perl
The path to the Perl executable to use for build steps that require it. Used primarily in the
test suite. Default: The binary named "perl" on the user's PATH.
pgp_key
Sign generated tarballs with the provided PGP key. The key can be named in any way that the -u
option of GnuPG understands. This can also be set in the global configuration file. There is no
default; if this option is not set, either as a constructor parameter or in the global
configuration file, the generated tarballs will not be signed.
INSTANCE METHODS
check_dist(SOURCE, TARBALL)
Given the path to a source directory and the path to a gzip-compressed distribution tarball made from
that directory, return the list of files that should be in the tarball but aren't. An empty list
means that all files in the source tree expected to be in the distribution are present.
This method is provided primarily for testing convenience and is normally just an implementation
detail of make_distribution().
commands()
Return the commands that should be run to generate a distribution tarball as a reference to an array
of arrays. Each included array is a single command.
This method is provided primarily for testing convenience and is normally just an implementation
detail of make_distribution().
make_distribution()
Generate distribution tarballs in the "destdir" directory provided to new(). The distribution will
be generated from the first branch found named either "main" or "master".
If "destdir" already contains a subdirectory whose name matches the "tarname" of the distribution, it
will be forcibly removed. In order to successfully remove trees that result from Automake's "make
distcheck" failing partway through, App::DocKnot::Dist will change permissions as needed to remove an
existing directory. For security reasons, the "distdir" parameter of this module should therefore
only be pointed to a trusted directory, not one where an attacker could have written files.
If the native distribution tarball generation commands for the package generate a gzip-compressed
tarball but not an xz-compressed tarball, an xz-compressed tarball will be created.
After the distribution is created, check_dist() will be run on it. If any files are missing from the
distribution, they will be reported to standard output and then an exception will be thrown.
If the "pgp_key" constructor parameter or global configuration option is set, the generated tarballs
will then be signed with that key, using gpg. The generated signature will be armored and stored in
a file named by appending ".asc" to the name of the tarball.
