From 4b0dcfdf9490d2182469c2a2ba5ff44aa2778bef Mon Sep 17 00:00:00 2001 From: mleku Date: Mon, 3 Nov 2025 19:55:14 +0000 Subject: [PATCH] Add cluster replication configuration and enhance event handling - Introduced support for cluster replication in the ORLY system, allowing for distributed relay clusters with active replication. - Updated the configuration to include a new option for propagating privileged events to relay peers. - Enhanced the `ClusterManager` to manage event propagation based on the new configuration setting. - Improved the handling of event fetching to respect the propagation settings, ensuring better privacy for privileged events. - Updated documentation to reflect the new cluster replication features and privacy considerations. - Bumped version to v0.24.3 to reflect these changes. --- app/config/config.go | 3 + app/main.go | 2 +- docs/NIP-XX-Cluster-Replication.md | 13 +-- pkg/sync/cluster.go | 136 +++++++++++++++++++++++------ pkg/version/version | 2 +- readme.adoc | 21 +++++ workaround_test.go | 55 ++++++++---- 7 files changed, 174 insertions(+), 58 deletions(-) diff --git a/app/config/config.go b/app/config/config.go index 9c8852c..490f1fa 100644 --- a/app/config/config.go +++ b/app/config/config.go @@ -73,6 +73,9 @@ type C struct { // TLS configuration TLSDomains []string `env:"ORLY_TLS_DOMAINS" usage:"comma-separated list of domains to respond to for TLS"` Certs []string `env:"ORLY_CERTS" usage:"comma-separated list of paths to certificate root names (e.g., /path/to/cert will load /path/to/cert.pem and /path/to/cert.key)"` + + // Cluster replication configuration + ClusterPropagatePrivilegedEvents bool `env:"ORLY_CLUSTER_PROPAGATE_PRIVILEGED_EVENTS" default:"true" usage:"propagate privileged events (DMs, gift wraps, etc.) to relay peers for replication"` } // New creates and initializes a new configuration object for the relay diff --git a/app/main.go b/app/main.go index 8cf7e9a..0ff10e9 100644 --- a/app/main.go +++ b/app/main.go @@ -164,7 +164,7 @@ func Run( } if len(clusterAdminNpubs) > 0 { - l.clusterManager = dsync.NewClusterManager(ctx, db, clusterAdminNpubs) + l.clusterManager = dsync.NewClusterManager(ctx, db, clusterAdminNpubs, cfg.ClusterPropagatePrivilegedEvents, l.publishers) l.clusterManager.Start() log.I.F("cluster replication manager initialized with %d admin npubs", len(clusterAdminNpubs)) } diff --git a/docs/NIP-XX-Cluster-Replication.md b/docs/NIP-XX-Cluster-Replication.md index e49244c..40b7bc8 100644 --- a/docs/NIP-XX-Cluster-Replication.md +++ b/docs/NIP-XX-Cluster-Replication.md @@ -39,14 +39,12 @@ Cluster administrators publish this replaceable event to define the current set ```json { "kind": 39108, - "content": "{\"name\":\"My Cluster\",\"description\":\"Community relay cluster\",\"admins\":[\"npub1...\",\"npub2...\"]}", + "content": "{\"name\":\"My Cluster\",\"description\":\"Community relay cluster\"}", "tags": [ ["d", "membership"], ["relay", "https://relay1.example.com/", "wss://relay1.example.com/"], ["relay", "https://relay2.example.com/", "wss://relay2.example.com/"], ["relay", "https://relay3.example.com/", "wss://relay3.example.com/"], - ["admin", "npub1admin..."], - ["admin", "npub1admin2..."], ["version", "1"] ], "pubkey": "", @@ -59,12 +57,11 @@ Cluster administrators publish this replaceable event to define the current set **Tags:** - `d`: Identifier for the membership list (always "membership") - `relay`: HTTP and WebSocket URLs of cluster member relays (comma-separated) -- `admin`: npub of cluster administrator (can have multiple) - `version`: Protocol version number -**Content:** JSON object containing cluster metadata (name, description, admin list) +**Content:** JSON object containing cluster metadata (name, description) -**Authorization:** Only events signed by cluster administrators (listed in `admin` tags) are valid for membership updates. +**Authorization:** Only events signed by cluster administrators are valid for membership updates.
