Deprecating official Rex packages

As part of our efforts to simplify maintenance around RexOps projects, we have decided to stop building Rex packages on our side. We recommend relying on OS packages maintained by the various distributions in their respective upstream repositories, or to install Rex from CPAN.

New site engine for rexify.org

After months of work on a new site backend, we reached the MVP today for our site to be switched over to a new engine: from now on, our site will be maintained using the static site generator Statocles.

Release notes for 1.3.0

These are the changes in the 1.3.0 release.

We want to thank every contributor who made this release possible. We also welcome Dmitry Kopytov as new contributor.

During this release cycle we tried to focus more on smoothing out the rougher edges and improving the documentation and test suite. Several aspects of the documentation work are mainly happening in the background and not in the codebase itself for now. So there are no "real" new features this time, but because of the amount of changes, and especially because of enabling the new template engine by default, we felt a new major release was warranted.

Enhancements

New template engine enabled by default

The enhanced template engine, template_ng, has been available since 0.56.0 via the similarly named feature flag. The main advantage of it is the ability to provide actually useful error messages when something goes wrong during template processing, while the format itself remains backward compatible with the previous template handling. There are some examples of those error messages on the original issue.

Automatic parallelism settings

It is now possible set parallelism of task execution more dynamically, e.g. by setting it to max, Rex detects the number of servers a task should be run on, and automatically executes it on all of them in parallel. Some other notation are recognized and supported as well, like max/3, or max 10%. For details, check out the documentation.

Tests

The local test suite has been greatly simplified as part of an ongoing improvement works. Those changes made the test suite ~30% faster and easier to maintain.

General

A bunch of general improvements happened in this release cycle as well, most notably:

All those happened in the following commits:

Documentation

We'd like to say thanks to Eric Johnson for an improved help screen and to Brian Manning for making it possible to list methods and DSL functions in the table of contents and linking to them directly within the page. We also added long-due documentation for the CMDB feature.

Bugfixes

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

Uploading files from Windows to Linux

File upload from Windows machines was fixed by checking the availability of uname and md5sum commands before trying to use them. This fix has been released as rex-1.2.1 as well.

do_task + before_task_start with modules

Fixed an issue when a task was specified in a module and had a before_task_start hook attached to it, then called with do_task from a different module.

General

This release also has some general fixes, most notably around sudo usage (like avoiding an endless loop when used together with auth for or suppressing warnings about missing locales).
