- Migrate 886 request.CTX parameters across 147 files to use consistent 'rctx' naming
- Updated function signatures from 'c', 'ctx', and 'cancelContext' to 'rctx'
- Updated function bodies to reference the new parameter names
- Preserved underscore parameters unchanged as they are unused
- Fixed method receiver context issue in store.go

Shared Channel Service

Package sharedchannel implements Mattermost's shared channels functionality, for sharing channel content across Mattermost instances/clusters. Here are the key responsibilities:

Channel Sharing:

  • Allows channels to be shared between different Mattermost instances/clusters
  • Handles inviting remote clusters to shared channels
  • Manages permissions and read-only status for shared channels

Content Synchronization:

  • Syncs posts, reactions, user profiles, and file attachments between instances
  • Handles permalink processing between instances
  • Manages user profile images sync
  • Maintains sync state and cursors to track what has been synchronized

Remote Communication:

  • Processes incoming sync messages from remote clusters
  • Sends updates to remote clusters when local changes occur
  • Handles connection state changes with remote clusters
  • Manages retry logic for failed sync attempts

Security:

  • Validates permissions for shared channel operations
  • Ensures users can only sync content they have access to
  • Verifies remote cluster authenticity
  • Sanitizes user data during sync

The service acts as a bridge between Mattermost instances, allowing users from different instances to collaborate in shared channels while keeping content synchronized across all participating instances.

This is implemented through a Service struct that handles all the shared channel operations and maintains the synchronization state. It works in conjunction with the RemoteCluster service to handle the actual communication between instances.
