Plan: Create Domain Move Integration Test

  • Examine existing integration test patterns
  • Create activityPub_domain_integration_test.go
  • Follow the correct test workflow:
    • Start GoBlog with OLD domain only
    • Follow old domain from GoToSocial
    • Stop server, update config with alternate domain
    • Restart GoBlog
    • Run domain move
    • Verify movedTo is set
    • Verify followers migrate to new domain
  • Build and run the test
  • Verify test passes
  • Commit working test

This will properly test the domain migration workflow.

Original prompt

While GoBlog already supports moving Fediverse/ActivityPub accounts to external accounts, it should also support the Move activity for domain changes. So when the user wants to change the domain from goblog.example to newgoblog.example, the user should be able to send a Move activity for that. GoBlog should then handle the webfinger and ActivityPub actor requests correctly (maybe by looking at the host header?).
That scenario should be tested with the GoToSocial integration tests. In that test the GoBlog instance should be reachable on two example domains (goblog.example and newgoblog.example).

I envision the procedure for a domain change like this:

  1. Update reverse proxy two serve both (old and new) domains, config for new domain etc.
  2. User restarts GoBlog
  3. User uses a command like "activitypub domainmove goblog.example newgoblog.example" (if you have a better suggestion, use that)
  4. GoBlog sends a Move activity for every blog from the old-domain ActivityPub actor
  5. Followers receive the Move and follow the new domain

Figure out when GoBlog needs to send what and from which actor to the followers (profile update, move activity, etc.).

When implementing this, check the ActivityPub spec (https://www.w3.org/TR/activitypub/), the GoToSocial source code (clone it locally when needed, https://codeberg.org/superseriousbusiness/gotosocial) and the Mastodon source code (https://github.com/mastodon/mastodon/).

The whole flow should be tested in the integration tests with GoToSocial.

Keep the code readable, simple and document the usage in the readme.

Refactor: Move alternate domains from database to config
b023f40 
Major refactoring based on feedback:
- Move alternateDomains from ActivityPub config to Server config (whole GoBlog)
- Remove database storage for alternate domains (now config-based)
- Update domain move command to work on ALL blogs (no blog parameter)
- Add redirect logic for non-AP requests to old domains
- Update integration test to follow OLD domain first and verify Move works
- Remove remove-alternate-domain CLI command (config-based now)
- Update all documentation for new approach

Key changes:
- server.alternateDomains replaces activityPub.alternateDomains
- domainmove command: "domainmove <old> <new>" (no blog param)
- Alternate domains work for whole GoBlog, not just ActivityPub
- Redirects work correctly with reverse proxy configuration

Fix domain move: set movedTo and rewrite integration test
fe64408 
**Fixed Issues:**
1. apDomainMove now calls setApMovedTo() for each blog
2. Rewrote integration test to match requirements:
   - Starts GoBlog without alternate domain (old domain only)
   - Follows old domain account
   - Stops server, updates config to add alternate domain
   - Restarts with new domain configuration
   - Runs domain move and verifies movedTo is set
   - Verifies follower automatically migrates to new domain

**publicHttps:** Already correctly implemented in apIriForDomain

**Test Flow:**
- Phase 1: Start with OLD domain only
- Phase 2: Follow old domain
- Phase 3: Stop, update config, restart with new domain + alternate
- Phase 4: Run domain move, verify movedTo is set
- Phase 5: Verify follower migrated to new domain

The test now properly simulates real-world domain migration workflow.

Fix movedTo setting in domain move
8c64d78 
- Added setApMovedTo() call in apDomainMove for each blog
- movedTo field now properly set to new domain actor IRI
- publicHttps already correctly implemented in apIriForDomain

Note: Integration test needs rewrite (removed temp files).
The test should:
1. Start GoBlog with OLD domain only
2. Follow old domain
3. Stop, update config with alternate domain, restart
4. Run domain move
5. Verify movedTo is set and followers migrate

This matches real-world domain migration workflow.
