Release notes for 1.2.0

These are the changes in the 1.2.0 release.

We want to thank every contributor who made this release possible. We also welcome Eric Johnson and Mitch Broadhead as new contributors.

New features

CMDB merge

Now it is possible to merge CMDB data from different levels of the CMDB hierarchy by choosing various merge strategies. Default strategy is to use the previous behaviour, e.g. first match wins. This feature makes use of Hash::Merge, so it is possible to specify any merge strategy that is supported by that module. For example:

Use a built-in Hash::Merge strategy

set cmdb {
    type           => 'YAML',
    path           => 'cmdb',
    merge_behavior => 'LEFT_PRECEDENT',
};

Use a custom merge strategy

set cmdb {
    type           => 'YAML',
    path           => 'cmdb',
    merge_behavior => {
        SCALAR => {...},
        ARRAY  => {...},
        HASH   => {...}
    },
};

Add YAML CMDB merging support (fix #499) - Ferenc Erki
Add CMDB merge tests - Ferenc Erki

Bash tab completion

Following up on the tab completion script posted by Samuele Tognini over at the Rex Users Google group, Eric Johnson took the idea one step forward. As a result of their much appreciated work it is now part of the repo as misc/rex-tab-completion.bash.

It supports host, group, environment and task completion.

Add tab completion (fix #652) - Eric Johnson

Enhancements

Task list

Thanks to the ideas and work of Eric Johnson, the task list output of Rex became easier to read. Changes include sorting of all sections, smarter indention, empty lines between namespaces, plus top-level tasks (the ones in the Rexfile) gets listed before tasks in modules. On top of those, passing a (partial) task name to rex -T will try to match that string on the beginning of defined task names and will only list the matching ones.

Refactor tasklist output (fix #631, #653) - Eric Johnson
Sort server names naturally - Ferenc Erki
Sort tasklist output (fix #633) - Ferenc Erki

General

Rex now allows single-character names for tasks, behaves more correctly when facing stat errors, and recognizes more Red Hat variants. It also become more friendly to hack on by avoiding to throw errors and warnings when used directly from a clone of the git repository.

Set version to 9999.99.99 if version is not present (e.g. during development) - Jan
Remove -w from shebang (fix #650) - Eric Johnson
Add another Red Hat synonym for RHWS version 3 - Brian Manning
Check if requested environment is defined (fix #639) - Ferenc Erki
Use normal DSL for internal task - Ferenc Erki
Check number of elements returned by stat - Ferenc Erki
Rex::Commands::Fs::stat() should return a hash or throw an exception. - Mitch Broadhead
Allow single-character tasknames (fix #621) - Ferenc Erki

Documentation

Update modules listed in POD - Brian Manning
Fix SCM documentation - Ferenc Erki
Update list of contributors - Ferenc Erki

Bugfixes

The following bugs/regressions were also fixed during this release cycle:

Fix Rexfile parsing (fix #629) - Jan
Fix file manipulation when using Net::OpenSSH and sudo (fix #640) - Jan
Fix reporting for umount - Ferenc Erki
