Module Version: 0.0993   Source   Latest Release: Pinto-0.09995

NAME ^

App::Pinto::Command::pull - pull archives from upstream repositories

VERSION ^

version 0.0993

SYNOPSIS ^

  pinto --root=REPOSITORY_ROOT pull [OPTIONS] TARGET ...

DESCRIPTION ^

This command locates packages in your upstream repositories and then pulls the distributions providing those packages into your repository and registers them on a stack. Then it recursively locates and pulls all the distributions that are necessary to satisfy their prerequisites. You can also request to directly pull particular distributions.

When locating packages, Pinto first looks at the packages that already exist in the local repository, then Pinto looks at the packages that are available on the upstream repositories.

COMMAND ARGUMENTS ^

Arguments are the targets that you want to pull. Targets can be specified as packages (with or without a version specification) or as distributions. Targets can be expressed in a number of ways, so please see "TARGETS" below for more information.

You can also pipe arguments to this command over STDIN. In that case, blank lines and lines that look like comments (i.e. starting with "#" or ';') will be ignored.

COMMAND OPTIONS ^

--cascade

!! THIS OPTION IS EXPERIMENTAL !!

When searching for a package (or one of its prerequisites), always take the latest satisfactory version of the package found amongst all the upstream repositories, rather than just taking the first satisfactory version that is found. Remember that Pinto only searches the upstream repositories when the local repository does not already contain a satisfactory version of the package.

--diff-style=STYLE

Controls the style of the diff reports. STYLE must be either concise or detailed. Concise reports show only one record for each distribution added or deleted. Detailed reports show one record for every package added or deleted.

The default style is concise. However, the default style can changed by setting the PINTO_DIFF_STYLE environment variable to your preferred STYLE. This variable affects the default style for diff reports generated by all other commands too.

--dry-run

Go through all the motions, but do not actually commit any changes to the repository. At the conclusion, a diff showing the changes that would have been made will be displayed. Use this option to see how upgrades would potentially impact the stack.

--no-fail

!! THIS OPTION IS EXPERIMENTAL !!

Normally, failure to pull a target (or its prerequisites) causes the command to immediately abort and rollback the changes to the repository. But if --no-fail is set, then only the changes caused by the failed target (and its prerequisites) will be rolled back and the command will continue processing the remaining targets.

This option is useful if you want to throw a list of targets into a repository and see which ones are problematic. Once you've fixed the broken ones, you can throw the whole list at the repository again.

--message=TEXT
-m TEXT

Use TEXT as the revision history log message. If you do not use the --message option or the --use-default-message option, then you will be prompted to enter the message via your text editor. Use the EDITOR or VISUAL environment variables to control which editor is used. A log message is not required whenever the --dry-run option is set, or if the action did not yield any changes to the repository.

--pin

Pins the packages to the stack, so they cannot be changed until you unpin them. Only the packages in the requested targets will be pinned -- packages in prerequisites will not be pinned. However, you may pin them separately with the pin command if you so desire.

--recurse
--no-recurse

Recursively pull any distributions required to satisfy prerequisites for the targets. The default value for this option can be configured in the pinto.ini configuration file for the repository (it is usually set to 1). To disable recursion, use --no-recurse.

--skip-missing-prerequisite=PACKAGE
-k PACKAGE

!! THIS OPTION IS EXPERIMENTAL !!

Skip any prerequisite with name PACKAGE if a satisfactory version cannot be found. However, a warning will be given whenever this occurrs. This option only has effect when recursively fetching prerequisites for the targets (See also the --recurse option). This option can be repeated.

--skip-all-missing-prerequisites
-K

!! THIS OPTION IS EXPERIMENTAL !!

Skips all missing prerequisites if a satisfactory version cannot be found. However, a warning will be given whenever this occurrs. This option will silently override the --skip-missing-prerequisite option and only has effect when recursively fetching prerequisites for the targets (See also the --recurse option).

--stack=NAME
-s NAME

Puts all the packages onto the stack with the given NAME. Defaults to the name of whichever stack is currently marked as the default stack. Use the stacks command to see the stacks in the repository.

--use-default-message
-M

Use the default value for the revision history log message. Pinto will generate a semi-informative log message just based on the command and its arguments. If you set an explicit message with --message, the --use- default-message option will be silently ignored.

--with-development-prerequisites
--wd

Also pull development prerequisites so you'll have everything you need to work on those distributions, in the event that you need to patch them in the future. Be aware that most distributions do not actually declare their development prerequisites.

TARGETS ^

Targets are a compact notation that identifies the things you want to pull into your repository. Targets come in two flavors: package targets and distribution targets.

Package Targets

A package target consists of a package name and (optionally) a version specification. Here are some examples:

  Foo::Bar                                 # Any version of Foo::Bar
  Foo::Bar~1.2                             # Foo::Bar version 1.2 or higher
  Foo::Bar==1.2                            # Only version 1.2 of Foo::Bar
  Foo::Bar<1,2!=1.3,<=1.9                  # Complex version range

Package names are case-sensitive, and the version specification must follow the format used by CPAN::Meta::Requirements. All whitespace within the target will be discarded. If your version specification contains any special shell characters, take care to quote or escape them in your command.

In all cases, pinto queries the local repository and then each upstream repository in order, and pulls the first distribution it can find that provides a package which satisfies the version specification.

Distribution Targets

A distribution target consists of an author ID, zero or more subdirectories, and the distribution name and version number. This corresponds to the actual path where the distribution archive lives in the repository or CPAN mirror. Here are some examples.

  SHAKESPEARE/King-Lear-1.2.tar.gz         # A specific distribution
  SHAKESPEARE/tragedies/Hamlet-4.2.tar.gz  # Same, but with a subdirectory

The author ID will always be forced to uppercase, but the reset of the path is case-sensitive.

Caveats

PAUSE has no strict rules on how packages are versioned. It is quite common to see a package with the same verison number (or no version at all) in many releases of a distribution. So when you specify a package target with a precise version or version range, what you actually get is the latest distribution (chronologically) that has a package which satisfies the target. Most of the time this works out fine because you usally pull the "main module" of the distribution and authors always increment that version in each release.

Since most CPAN mirrors only report the latest version of a package they have, they often cannot satisfy package targets that have a precise version specification. However, the mirror at http://cpan.stratopan.com is special and can locate a precise version of any package.

Package targets always resolve to production releases, unless you specify a precise developer release version (e.g. Foo::Bar==1.03_01). But since most CPAN mirrors do not index developer releases, this only works when using the mirror at http://cpan.stratopan.com. However, you can usually pull a developer release from any mirror by using a distribution target. Remember that developer releases are those with an underscore in the version number.

For repositories created with Pinto version 0.098 or later, the first upstream source is http://cpan.stratopan.com (unless you configure it otherwise). For repositories created with older versions, you can manually add http://cpan.stratopan.com to the sources parameter in the configuration file located at .pinto/config/pinto.ini within the repository.
