Automate Hammer CLI release notes integration #2242

ogajduse · 2025-08-27T12:25:35Z

Summary

Automate Hammer CLI release notes integration in scripts/release_notes.rb
Add configurable category mapping system for maintainable transformations
Eliminate manual copy-paste work for Hammer CLI components during releases

Background

Manual integration of Hammer CLI release notes into Foreman documentation is time-consuming and error-prone during releases. This addresses theforeman/theforeman-rel-eng#514 by automating the process through the existing release_notes.rb script.

Changes Made

Core Functionality

Extended release_notes.rb to fetch both hammer-cli and hammer-cli-foreman release notes from Redmine
Added support for version prefixes (e.g., hammer-cli-3.16.0, hammer-cli-foreman-3.16.0)
Integrated Hammer CLI sections into the existing release notes workflow

Configurable Category Mapping System

Replaced hardcoded category transformations with configurable CATEGORY_MAPPINGS
Added support for:
- Merge mappings: Combine multiple source categories into target categories
- Project-specific transformations: Apply different rules based on component type
- Regex-based renaming: Flexible pattern matching for category names

Output Format

The script now automatically generates properly formatted Hammer CLI sections:

+#### Hammer CLI - Hammer core
+* Translated paths for replaced_by fields may differ from actual path ([#38427](https://projects.theforeman.org/issues/38427))
+
+#### Hammer CLI - Foreman - Compute resources
+* Remove Ovirt from Hammer ([#38294](https://projects.theforeman.org/issues/38294))
+
+#### Hammer CLI - Foreman - Users and roles
+* LDAP group membership ([#38611](https://projects.theforeman.org/issues/38611))

Usage

ruby scripts/release_notes.rb foreman 3.16.0

Now automatically includes Hammer CLI and Hammer CLI - Foreman sections alongside Foreman release notes.

Benefits

✅ Eliminates manual work: No more copy-paste from Hammer CLI repositories
✅ Maintains consistency: Automated formatting ensures uniform output
✅ Easily extensible: New category mappings can be added without code changes

I think this looks very complex and would suggest to start fresh. My recommendation would be to take https://github.com/theforeman/foreman-documentation/blob/master/guides/doc-Release_Notes/redmine_release_notes as a base. Then work on expanding that.

The first thing I would try is the trick I suggest inline with repeating v[cf_12][] multiple time, once for each release you want to include.

It also already cleaner where category_from_issue is already the method to extract the category from an issue. I think that's a better base then the complex mapping here.

Once you have the version in foreman-documentation working then I'd suggest to replace the script in this repo with a version that spits out markdown instead of asciidoc.

scripts/release_notes.rb

 rescue StandardError => e
  puts "Error getting version list from #{url}: #{e}"
-  exit 1
+  return nil


I think this should still exit if it fails. It may not be very clean, but it's a simple script and it's good enough error handling.

Suggested change

return nil

exit 1

scripts/release_notes.rb

+].freeze
+
+# Category mappings and transformations
+CATEGORY_MAPPINGS = {


I think this is too complex. Why don't you simplify this to various separate constants?

ekohl · 2025-09-02T15:39:42Z

scripts/release_notes.rb

+  # Rename categories - simple string replacements using regex patterns
+  rename: {
+    /^Hammer CLI$/ => 'Hammer CLI',  # Keep as-is for base hammer-cli
+  },


What's the point of this noop rename? Feels like this can just be dropped.

ekohl · 2025-09-02T15:44:57Z

scripts/release_notes.rb

+  CATEGORY_MAPPINGS[:merge].each do |target_category, source_categories|
+    grouped_issues[target_category] ||= []  # Initialize if doesn't exist
+    source_categories.each do |source_category|
+      if grouped_issues.key?(source_category)
+        # Move issues from source to target category and remove source
+        grouped_issues[target_category] += grouped_issues.delete(source_category)
+      end
+    end
+  end


This feels way overengineered. The previous code was easier to understand IMHO. Now you have ~15 lines of code for what used to be 2 lines.

ekohl · 2025-09-02T15:45:30Z

scripts/release_notes.rb

+  # Step 3: Apply general rename mappings
+  new_grouped_issues = {}
+  grouped_issues.each do |category, category_issues|
+    new_category = category
+    CATEGORY_MAPPINGS[:rename].each do |pattern, replacement|
+      new_category = new_category.gsub(pattern, replacement)
+    end
+    new_grouped_issues[new_category] = category_issues
+  end


The whole renaming isn't used so I think this can be dropped

Suggested change

# Step 3: Apply general rename mappings

new_grouped_issues = {}

grouped_issues.each do |category, category_issues|

new_category = category

CATEGORY_MAPPINGS[:rename].each do |pattern, replacement|

new_category = new_category.gsub(pattern, replacement)

end

new_grouped_issues[new_category] = category_issues

end

scripts/release_notes.rb

+  # Project-specific category transformations
+  project_specific: {
+    'hammer-cli-foreman-' => {
+      /^Hammer CLI/ => 'Hammer CLI - Foreman'
+    }
+  }


This took me a long time to figure out and again, IMHO a bit too complex.

ekohl · 2025-09-02T15:52:18Z

scripts/release_notes.rb

+  generate_release_notes_for_project(project_config[:project], @current_release_name, project_config[:version_prefix])
 end

 puts "*A full list of changes in #{@current_release_name} is available via [Redmine](https://projects.theforeman.org/issues?set_filter=1&sort=id%3Adesc&status_id=closed&f[]=cf_12&op[cf_12]=%3D&v[cf_12]=#{@current_release_id})*"


This is no longer true because you also need to include the Hammer releases.

ekohl · 2025-09-02T15:58:35Z

scripts/release_notes.rb

-    'v[cf_12][]' => @current_release_id,
+    'f[]' => 'cf_12',           # Filter by custom field 12 (Fix version)
+    'op[cf_12]' => '=',         # Operator: equals
+    'v[cf_12][]' => release_id, # Value: the release ID we want


You can repeat this parameter to gather the issues for multiple releases in a single API call. I think you can just change params to an array of arrays and repeat v[cf12][] for each release you want to include.

ekohl · 2025-09-02T16:03:27Z

scripts/release_notes.rb


-grouped_issues = gather_issues.group_by { |issue| "#{issue['project']['name']}#{ ' - ' + issue['category']['name'] if issue.key?('category') }" }
+  # Sort categories alphabetically
+  grouped_issues = Hash[ grouped_issues.sort_by { |key, val| key } ]


I know this existed before, but this can be done easier in current Ruby (probably couldn't when it was written). The version in foreman-documentation already does this.

Suggested change

grouped_issues = Hash[ grouped_issues.sort_by { |key, val| key } ]

grouped_issues = grouped_issues.sort
