Add getOrCreateRemoteUser() method to create/retrieve remote users on-demand - Use plugin API to find existing users by username/email before creating new ones - Generate usernames with bridge prefix and emails with bridge.{bridgeID} domain - Set RemoteId field to BridgeMessage.SourceRemoteID for proper loop prevention - Cache user mappings to avoid repeated API calls - Post messages directly as remote users instead of bot with metadata - Remove unused message formatting since messages are posted as actual users - Log errors for failed user creation without complex retry logic This enables authentic user attribution in Mattermost channels while maintaining existing loop prevention mechanisms through the RemoteId field. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- server/bridge/mattermost/message_handler.go | 154 ++++++++++++++++---- 1 file changed, 124 insertions(+), 30 deletions(-) diff --git a/server/bridge/mattermost/message_handler.go b/server/bridge/mattermost/message_handler.go index 691ae7f..0291066 100644 --- a/server/bridge/mattermost/message_handler.go +++ b/server/bridge/mattermost/message_handler.go @@ -3,6 +3,7 @@ package mattermost import ( "fmt" "strings" + "sync" "github.com/mattermost/mattermost-plugin-bridge-xmpp/server/logger" pluginModel "github.com/mattermost/mattermost-plugin-bridge-xmpp/server/model" @@ -11,15 +12,18 @@ import ( // mattermostMessageHandler handles incoming messages for the Mattermost bridge type mattermostMessageHandler struct { -

Add comprehensive loop prevention at source level for all bridges: - XMPP bridge: Skip messages from own XMPP connection user - Mattermost bridge: Skip messages from bot user and remote users - Remove cache from getOrCreateRemoteUser method for simplified user management - Improve XMPP client architecture with direct handler delegation: - Add SetMessageHandler and GetJID methods to XMPP client - Move protocol normalization methods to client level - Implement handleIncomingXMPPMessage in XMPP bridge for business logic - Fix message direction handling in XMPP message handler - Add remote user invitation to shared channels via InviteRemoteToChannel API - Clean up unused code and improve code formatting 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- server/bridge/manager.go | 2 +- server/bridge/mattermost/message_handler.go | 49 +++++++-------------- server/bridge/xmpp/bridge.go | 14 ++++-- server/bridge/xmpp/message_handler.go | 2 +- server/hooks_sharedchannels.go | 35 +++++++++++++-- server/xmpp/client.go | 5 +++ 6 files changed, 63 insertions(+), 44 deletions(-) diff --git a/server/bridge/manager.go b/server/bridge/manager.go index 042b5cb..6f5683c 100644 --- a/server/bridge/manager.go +++ b/server/bridge/manager.go @@ -278,7 +278,7 @@ func (m *BridgeManager) CreateChannelMapping(req model.CreateChannelMappingReque return fmt.Errorf("bridge '%s' is not connected", req.BridgeName) } -

settings configuration +3. **Activation**: Component initialization and bridge startup +4. **Operation**: Real-time message synchronization +5. **Updates**: Hot configuration reload without restart +6. **Maintenance**: Health monitoring and log analysis + +### Monitoring & Observability +- **Health Endpoints**: Bridge connectivity status +- **Structured Logging**: JSON-formatted log entries +- **Metrics Collection**: Message throughput and error rates +- **Alerting**: Failed connection and mapping error notifications + +## Development Workflow + +### Prerequisites +- Go 1.21+ for server development +- Node.js 18+ for webapp development +- Docker for XMPP test server +- golangci-lint for code quality + +### Key Commands +```bash +make # Build plugin bundle +make test # Run all tests +make check-style # Lint and format +make deploy # Deploy to local Mattermost +make devserver_start # Start test XMPP server +``` + +### XMPP Client Doctor Tool (`cmd/xmpp-client-doctor/`) +The doctor command provides comprehensive XMPP connectivity and feature testing: + +```bash +# Basic connectivity test +go run ./cmd/xmpp-client-doctor/main.go + +# Test specific features +go run ./cmd/xmpp-client-doctor/main.go --test-xep0077 --test-muc --test-dm + +# Custom server testing +go run ./cmd/xmpp-client-doctor/main.go --server example.com:5222 --username user@example.com +``` +
