pip3 install lockss-turtles

!DANGER!

Do not run pip3/pip as root, with sudo or otherwise.

Overview

Building Plugins

You can use Turtles to build (package and sign) LOCKSS plugins from one or more LOCKSS plugin sets (codebases containing plugins).

You will need to define one or more Plugin Sets, list them in a Plugin Set Catalog, and declare your Plugin Signing Credentials.

You then use the build-plugin command to build plugins, or the release-plugin command to build and deploy plugins (equivalent of build-plugin followed by deploy-plugin).

Deploying Plugins

You can use Turtles to deploy LOCKSS plugins to LOCKSS plugin registries.

You will need to define one or more Plugin Registries and declare them in a Plugin Registry Catalog.

You then use the deploy-plugin command to deploy plugin JARs, or the release-plugin command to build and deploy plugins from Plugin Sets (equivalent of build-plugin followed by deploy-plugin).

Configuration Files

All Turtles configuration files are YAML files and have a top-level kind key that declares what kind of configuration file it is.

Some Turtles commands require a Plugin Set Catalog, Plugin Registry Catalog, or Plugin Signing Credentials. You can specify the configuration file to use via the appropriate command line option (for example --plugin-set-catalog/-s). Otherwise, Turtles will look for then appropriate configuration file (for example plugin-set-catalog.yaml) in several standard directories, in this order:

• $XDG_CONFIG_HOME/lockss.turtles (by default $HOME/.config/lockss.turtles)

• /usr/local/share/lockss.turtles

• /etc/lockss.turtles

Plugin Set Catalog

Turtles commands that are Building Plugins (build-plugin, release-plugin) need a plugin set catalog. It can be specified via the --plugin-set-catalog/-s option, otherwise Turtles looks through Configuration Files for a file named plugin-set-catalog.yaml.

A plugin set catalog is defined by a YAML document:

---
kind: PluginSetCatalog
plugin-set-files:
  - /path/to/some/file1.yaml
  - /path/to/another/file2.yaml
  - ...

The contents are described below:

kind

Required. Must be set to PluginSetCatalog.

plugin-set-files

Required. A list of one or more paths to Plugin Sets.

Plugin Sets

A plugin set is a project containing the source code of one or more LOCKSS plugins.

A plugin set is defined by a YAML document:

---
kind: PluginSet
id: mypluginset
name: My Plugin Set

  type: ...
  ...

The contents are described below:

kind

Required. Must be set to PluginSet.

id

Additional properties depending on the plugin set builder type. See Plugin Set Builders below.

Plugin Set Builders

Turtles Plugin Sets support two types of plugin set builders:

• Maven Plugin Set Builder

• Ant Plugin Set Builder

Maven Plugin Set Builder

This type of plugin set builder is for a Maven project inheriting from org.lockss:lockss-plugins-parent-pom.

Maven Plugin Set Builder Prerequisites

• Java Development Kit 8 (JDK).

• Apache Maven.

Maven Plugin Set Builder Declaration

For this plugin set builder type, the builder object in the plugin set definition has the following structure:

kind: PluginSet
id: ...
name: ...
builder:
  type: mvn
  main: ...
  test: ...

type

main

Optional. The path (relative to the root of the project) to the plugins’ source code. Default: src/main/java.

test

Optional. The path (relative to the root of the project) to the plugins’ unit tests. Default: src/test/java.

Ant Plugin Set Builder

This type of plugin set builder is for the LOCKSS 1.x (https://github.com/lockss/lockss-daemon) code tree, based on Ant.

Ant Plugin Set Builder Prerequisites

• Java Development Kit 8 (JDK).

• Apache Ant.

• JAVA_HOME must be set appropriately.

Ant Plugin Set Builder Declaration

For this plugin set builder type, the builder object in the plugin set definition has the following structure:

---
kind: PluginSet
id: ...
name: ...
builder:
  type: ant
  main: ...
  test: ...

type

Required. Must be set to ant.

main

Optional. The path (relative to the root of the project) to the plugins’ source code. Default: plugins/src.

test

Optional. The path (relative to the root of the project) to the plugins’ unit tests. Default: plugins/test/src.

Plugin Registry Catalog

Turtles commands that are Deploying Plugins (deploy-plugin, release-plugin) need a plugin registry catalog. It can be specified via the --plugin-registry-catalog/-r option, otherwise Turtles looks through Configuration Files for a file named plugin-registry-catalog.yaml.

A plugin set catalog is defined by a YAML document:

---
kind: PluginRegistryCatalog
plugin-registry-files:
  - /path/to/some/file1.yaml
  - /path/to/another/file2.yaml
  - ...

The contents are described below:

kind

Required. Must be set to PluginRegistryCatalog.

plugin-registry-files

Required. A list of one or more paths to Plugin Registries.

Plugin Registries

A plugin registry is a structure containing LOCKSS plugins packaged as signed JAR files.

Currently the only predefined structures are directory structures local to the file system, which are then typically served by a Web server.

A plugin registry is defined by a YAML document:

---
kind: PluginRegistry
id: mypluginregistry
name: My Plugin Registry
layout:
  type: ...
  ...
layers:
  - ...
plugin-identifiers:
  - edu.myuniversity.plugin.publisherx.PublisherXPlugin
  - edu.myuniversity.plugin.publishery.PublisherYPlugin
  - ...
suppressed-plugin-identifiers:
  - edu.myuniversity.plugin.old.OldPlugin
  - ...

The contents are described below:

kind

Required. Must be set to PluginRegistry.

id

Required. A short identifier for the plugin registry, for example mypluginregistry.

name

Required. A display name for the plugin registry, for example My Plugin Registry.

layout

Required. An object defining the plugin registry’s layout together with its options.

type

Required. A plugin registry layout type. See Plugin Registry Layouts below.

Other

Additional properties depending on the plugin registry layout type. See Plugin Registry Layouts below.

layers

Required. A list of objects describing the layers of the plugin registry. See Plugin Registry Layers below.

plugin-identifiers

Required. Non-empty list of the plugin identifiers in this plugin registry.

suppressed-plugin-identifiers

Optional. Non-empty list of plugin identifiers that are excluded from this plugin registry.

Turtles does not currently do anything with this information, but it can be used to record plugins that have been abandoned or retracted over the lifetime of the plugin registry.

Plugin Registry Layouts

Turtles supports two kinds of plugin registry layouts:

• Directory Plugin Registry Layout

• RCS Plugin Registry Layout

Directory Plugin Registry Layout

In this type of plugin registry layout, each layer consists of a directory on the local file system where signed plugin JARs are stored, which is then typically served by a Web server. The directory for each layer is designated by the layer’s path property.

Directory Plugin Registry Layout Prerequisites

None.

Directory Plugin Registry Layout Declaration

For this plugin registry layout type, the layout object in the plugin registry definition has the following structure:

---
kind: PluginRegistry
id: ...
name: ...
layout:
  type: directory
  file-naming-convention: ...
layers:
  - ...
plugin-identifiers:
  - ...
suppressed-plugin-identifiers:
  - ...

type

Required. Must be set to directory.

file-naming-convention

Optional. A rule for what to name each deployed JAR file. If unspecified, the behavior is that of identifier. Can be one of:

• identifier: Use the plugin identifier and add .jar. For example edu.myuniversity.plugin.publisherx.PublisherXPlugin results in edu.myuniversity.plugin.publisherx.PublisherXPlugin.jar.

• underscore: Replace . in the plugin identifier with _, and add .jar. For example edu.myuniversity.plugin.publisherx.PublisherXPlugin results in edu_myuniversity_plugin_publisherx_PublisherXPlugin.jar.

• abbreviated: Use the last dotted component of the plugin identifier and add .jar. For example edu.myuniversity.plugin.publisherx.PublisherXPlugin results in PublisherXPlugin.jar.

RCS Plugin Registry Layout

In this specialization of the Directory Plugin Registry Layout, each successive version of a given JAR is kept locally in RCS.

RCS Plugin Registry Layout Prerequisites

• GNU RCS.

RCS Plugin Registry Layout Declaration

For this plugin registry layout type, the layout object in the plugin registry definition has the following structure:

---
kind: PluginRegistry
id: ...
name: ...
layout:
  type: rcs
  file-naming-convention: ...
layers:
  - ...
plugin-identifiers:
  - ...
suppressed-plugin-identifiers:
  - ...

type

Required. Must be set to rcs.

file-naming-convention

Optional. A rule for what to name each deployed JAR file. If unspecified, the behavior is that of identifier. Can be one of:

• identifier: Use the plugin identifier and add .jar. For example edu.myuniversity.plugin.publisherx.PublisherXPlugin results in edu.myuniversity.plugin.publisherx.PublisherXPlugin.jar.

• underscore: Replace . in the plugin identifier with _, and add .jar. For example edu.myuniversity.plugin.publisherx.PublisherXPlugin results in edu_myuniversity_plugin_publisherx_PublisherXPlugin.jar.

• abbreviated: Use the last dotted component of the plugin identifier and add .jar. For example edu.myuniversity.plugin.publisherx.PublisherXPlugin results in PublisherXPlugin.jar.

Plugin Registry Layers

A plugin registry consists of one or more layers.

Some plugin registries only one layer, in which case the LOCKSS boxes in a network using the plugin registry will get what is released to it. Some plugin registries may have two or more layers, with the additional layers used for plugin development or content processing quality assurance.

Layers are sequential in nature; a new version of a plugin is released to the lowest layer first, then to the next layer (after some process), and so on until the highest layer. This sequencing is reflected in the ordering of the layers list in the plugin registry definition.

Although the identifiers (see id below) and display names (see name below) of plugin registry layers are arbitrary, the highest layer is commonly referred to as the production layer, and when there are exactly two layers, the lower layer is commonly referred to as the testing layer. Turtles reflects this common idiom with built-in --production/-p and --testing/-t options that are shorthand for --layer=production and --layer=testing respectively.

It is possible for multiple plugin registries to have a layer path in common. An example would be a team working on several plugin registries for different purposes, having distinct (public) production layer paths, but sharing a single (internal) testing layer path, if they are the only audience for it.

A plugin registry layer is defined as one of the objects in the plugin registry definition’s layers list. Each layer object has the following structure:

---
kind: PluginRegistry
id: ...
name: ...
layout:
  type: ...
  ...
layers:
  - id: testing
    name: My Plugin Registry (Testing)
    path: /path/to/testing
  - id: production
    name: My Plugin Registry (Production)
    path: /path/to/production
  - ...
plugin-identifiers:
  - ...
suppressed-plugin-identifiers:
  - ...

id

Required. A short identifier for the plugin registry layer, for example testing.

name

Required. A display name for the plugin registry layer, for example My Plugin Registry (Testing).

path

Required. The local path to the root of the plugin registry layer, for example /path/to/testing.

Plugin Signing Credentials

Turtles commands that are Building Plugins (build-plugin, release-plugin) need a reference to plugin signing credentials. They can be specified via the --plugin-signing-credentials/-c option, otherwise Turtles looks through Configuration Files for a file named plugin-signing-credentials.yaml.

Plugin signing credentials are defined by a YAML document:

---
kind: PluginSigningCredentials
plugin-signing-keystore: /path/to/myalias.keystore
plugin-signing-alias: myalias

The contents are described below:

kind

Required. Must be set to PluginSigningCredentials.

plugin-signing-keystore

Required. Path to the plugin signing key (keystore).

plugin-signing-alias

Required. The alias to use, which must be that of the plugin signing key (keystore) and also found in the LOCKSS network’s shared keystore.

Command Line Tool

Turtles is invoked at the command line as:

turtles

or as a Python module:

python3 -m lockss.turtles

Help messages and this document use turtles throughout, but the two invocation styles are interchangeable.

                        layers to process

The command needs:

• A Plugin Registry Catalog, either from the --plugin-registry-catalog/-r option or from plugin-signing-credentials.yaml in the Configuration Files.

• One or more plugin registry layer IDs, from the Plugin Registry Layer Options (--layer/-l options, --layers/-L options, and alternatively, --testing/-t options, --production/-p option).

• One or more JAR paths. The list of JAR paths to process is derived from:

Options

Plugin Identifier Arguments and Options

Commands that are Building Plugins expect one or more plugin identifiers. The list of plugin identifiers to process is derived from:

• The plugin identifiers listed as bare arguments to the command.

• The plugin identifiers listed as --identifier/-i options.

• The plugin identifiers found in the files listed as --identifiers/-I options.

Plugin Registry Layer Options

Commands that are Deploying Plugins expect one or more plugin registry layer IDs. The list of plugin registry layer IDs to target is derived from:

• The plugin registry layer IDs listed as --layer/-l options.

• The plugin registry layer IDs found in the files listed as --layers/-L options.

As a convenience, the following synonyms also exist:

• --testing/-t is a synonym for --layer=testing

• --production/-p is a synonym for --layer=production

Output Format Control

Turtles’ tabular output is performed by the tabulate library through the --output-format option. See its PyPI page for a visual reference of the various output formats available. The default is simple.
