# Changelog

## v2.8.1

* Fix a missing `require` when using `subclass_providers!` on Chef 12.3.

## v2.8.0

* Chef 13 compatibility.
* Passing a symbol for the parent now works with the `include Poise(:name)`
  shortcut.
* Fixed `subclass_providers!` on older versions of Chef.

## v2.7.2

* Test harness fixes for Chef.

## v2.7.1

* Minor tweak for compatability with Chef master.

## v2.7.0

* More compatibility improvements for Chef 12.9.
* New helper: `Poise::Helpers::Win32User` to automatically convert `'root'`
  defaults for user and group properties to more platform-appropriate values.
* Enhanced `poise_shell_out` to better cope with Windows command parsing. Use
  Bash-style commands and it will automatically convert.
* Overall compatibility fixes for Windows.

## v2.6.1

* Compatibility with Chef master to fix issues with `defined_in!` not ignoring
  stack frames from Chef code.
* Setting a provider in a inversion options resource now works as (probably)
  expected.

## v2.6.0

* New backwards-compatibility helper: `Poise::Backports::VERIFY_PATH`. Use it
  like `verify "myapp -t #{Poise::Backports::VERIFY_PATH}" if defined?(verify)`
  for backwards-compatible usage of file verifications.
* Fixed Poise's implementation of lazy defaults to more closely match Chef's
  even when both are used in conjunction. Lazy defaults will no longer be
  evaluated when setting a value or getting an existing non-default value.

## v2.5.0

* New property for inversion resources: `provider_no_auto`. Set one or more
  provider names that will be ignored for automatic resolution for that instance.
* Support `variables` as an alias for `options` in template content properties
  to match the `template` resource.
* Template content properties are no longer validated after creation for
  non-default actions.
* Formalize the extra-verbose logging mode for Poise and expose it via helpers.
* Extra-verbose logging mode can now be enabled by creating a `/poise_debug` file.
* New helper: `poise_shell_out`. Like normal `shell_out` but sets group and
  environment variables automatically to better defaults.

## v2.4.0

* Added return value to `Container#register_subresource` to track if the resource
  was already added.
* Improve inspect output for subresources and containers.
* Ensure notifications work with subresources.
* Inversion providers process name equivalences.

## v2.3.2

* Improve handling of deeply nested subresources.

## v2.3.1

* Ensure a container with a parent link to its own type doesn't use self as the
  default parent.
* Improve handling of `load_current_resource` in providers that call it via
  `super`.

## v2.3.0

* New helper: `ResourceSubclass`, a helper for subclassing a resource while
  still using the providers as the base class.
* New feature: Non-default containers. Use `container_default: false` to mark
  a container class as ineligible for default lookup.
* New feature: parent attribute defaults. You can set a `parent_default` to
  provide a default value for the parent of a resource. This supports the
  `lazy { }` helper as with normal default values.
* New feature: use `forced_keys: [:name]` on an option collector property to
  force keys that would otherwise be clobbered by resource methods.
* Can enable verbose logging mode via a node attribute in addition to an
  environment variable.

## v2.2.3

* Add `ancestor_send` utility method for use in other helpers.
* Improve subresource support for use in mixins.

## v2.2.2

* Fix 2.2.1 for older versions of Chef.

## v2.2.1

* Fixed delayed notifications inside `notifying_block`.
* Default actions as expected within LWRPs.

## v2.2.0

* Compatibility with Chef 12.4.1 and Chefspec 4.3.0.
* New helper `ResourceCloning`: Disables resource cloning between Poise-based
  resources. This is enabled by default.
* Subresource parent references can be set to nil.

## v2.1.0

* Compatibility with Chef 12.4.
* Add `#property` as an alias for `#attribute` in resources. This provides
  forward compatibility with future versions of Chef.
* Freeze default resource attribute values. **This may break your code**,
  however this is not a major release because any code broken by this change
  was itself already a bug.

## v2.0.1

* Make the ChefspecHelpers helper a no-op if chefspec is not already loaded.
* Fix for finding the correct cookbook for a file when using vendored gems.
* New flag for the OptionCollector helper, `parser`:

```ruby
class Resource < Chef::Resource
  include Poise
  attribute(:options, option_collector: true, parser: proc {|val| parse(val) })

  def parse(val)
    {name: val}
  end
end
```

* Fix for a possible infinite loop when using `ResourceProviderMixin` in a nested
  module structure.

## v2.0.0

Major overhaul! Poise is now a Halite gem/cookbook. New helpers:

* ChefspecMatchers – Automatically create Chefspec matchers for Poise resources.
* DefinedIn – Track which file (and cookbook) a resource or provider is defined in.
* Fused – Experimental support for defining provider actions in the resource class.
* Inversion – Support for end-user dependency inversion with providers.

All helpers are compatible with Chef >= 12.0. Chef 11 is now deprecated, if you
need to support Chef 11 please continue to use Poise 1.

## v1.0.12

* Correctly propagate errors from inside notifying_block.

## v1.0.10

* Fixes an issue with the LWRPPolyfill helper and false values.


## v1.0.8

* Delayed notifications from nested converges will still only run at the end of
  the main converge.

## v1.0.6

* The include_recipe helper now works correctly when used at compile time.

## v1.0.4

* Redeclaring a template attribute with the same name as a parent class will
  inherit its options.

## v1.0.2

* New template attribute pattern.

```ruby
attribute(:config, template: true)

...

resource 'name' do
  config_source 'template.erb'
end

...

new_resource.config_content
```

## v1.0.0

* Initial release!
