Deadlock workaround

Works around an issue where updating conversation counters can cause deadlocks. The architecture is a little flawed, and this is an inelegant solution.

Adds conversation search, with options to search by recipient

Users must be a member of the conversation to see the conversation in search results.

Does not permit moderators/administrators to see another person's conversations in search results.

Due to XenForo's design, this addon impacts general 'everything' search as per search handler constrains are not invoked resulting in false positives which are removed by XenForo rather than the search subsystem.

Adds each conversation, and conversation message do the XenForo Search store (MySQL or Elastic Search), which may result in a larger search index.

New Conversation Permissions

Just takes away a user's "reply" button, no banners.

The reply limit is for the entire conversation, but the limit is per user group. Consider when User A & User B are members of a conversation.

User A can have a reply limit of 5. User B can have a reply limit of 10.

Once the conversation has >5 replies, User A can no longer post. Once the conversation has >10 replies, User A and User B can no longer post

Manual post-installation steps - Rebuild Search Index

On installing for the first time, please rebuild the Search Index for the following content types:
  • Conversation
  • Conversation Messages
Performance impact

1 extra query per conversation message posted due to indexing, and indexing itself.


I recommend using Add-on install & upgrade or Install and Upgrade by waindigo to install this addon.
