  * Fix root cause of missing stores/index after import: replicate_index()
    had an initial_sync_ok_ guard that silently dropped index replication
    whenever a node hadn't completed sync_from_cluster first. This meant
    create_store, add_media, and all CRUD operations never pushed the index
    to the cluster on a fresh node or after restart. Removed the guard;
    the empty-index check (local_count == 0) is sufficient protection.
  * Fix import hang: removed the post-import verification phase that fetched
    every media blob from the cluster under exclusive lock.
  * Fix stuck importing_ flag: RAII guard ensures it's always cleared.

  * Fix import + tombstone conflict: importing stores that were previously
    deleted caused tombstones to immediately re-delete them on the next sync.
    Import now clears tombstones for all imported store IDs and replicates the
    cleared tombstone list to the cluster. Also fixed replicate_tombstones()
    to push even when the set is empty, so cleared tombstones actually
    propagate to other nodes.

  * Prevent stale index overwrite: replicate_index() now compares local
    store count against cluster store count and refuses to push a smaller
    index. This prevents nodes that haven't synced yet from overwriting
    a freshly imported index with their empty/stale version. delete_store
    uses force=true to bypass the guard when a store was intentionally
    removed. repair_replication only re-replicates the index if the
    local node actually has stores.

  * Streaming cluster import: each media blob is now written directly to

  * Fix index replication deadlock: repair_replication() no longer requires
    initial_sync_ok_ to re-replicate the index. Previously, if the index
    was only on 1/3 nodes after restart, all nodes were stuck: sync_from_cluster
    couldn't fetch the index, and repair_replication refused to run because
    initial_sync_ok was false. Now the index is always repaired if under-replicated,
    which unblocks the other nodes' sync.

  * Fix local storage (BinDb): close ofstream before calling mmap_store()
    in append_media_locked and append_album_locked — the open stream
    prevented MAP_PRIVATE from seeing the newly written data, causing
    uploaded images to be returned as corrupt/empty

mediadb (20260407+73) unstable; urgency=medium

  * Fix cluster sync: load_store_metadata_from_buffer no longer seeks past
    non-existent inline media data, which caused all albums/media after the
    first to be lost on synced nodes

    stay up to date with index and store metadata
  * Add on-miss cluster sync for get_store, get_album, get_media and
    is_media_public — cache miss triggers immediate sync_from_cluster

    when local pending_data is empty, no early abort on metadata miss

  * Remove background sync thread: start_sync() loads from cluster once at
    startup, no periodic overwrites of imported data
  * Cluster-only storage: read_media_data fetches store blob from cluster
    on demand instead of keeping all media in RAM
  * sync_from_cluster loads only metadata (skips media data) to save RAM

mediadb (20260405+63) unstable; urgency=medium

  * Fix albums disappearing after cluster import: keep cluster_op_mutex_
    held during replication to prevent sync_from_cluster from overwriting
    newly imported data with stale cluster state
  * Still avoid BinDb::mutex_ during network I/O by collecting replication
    buffers first, then sending after import_from_stream releases mutex_

  * Fix cluster import blocking all reads: collect replication buffers under

    (not just at the end) for crash consistency

    was read after std::move, causing phantom empty albums on restart/sync
  * Fix same use-after-move in MDS1/MDS2 legacy reader and add_media_metadata
  * Chown data directory to run_user before dropping privileges
  * Add error_message() to ImportSession; report write errors to client
  * Check store file open/write errors during import

  * Import replicates each store directly to cluster during parsing
  * No more two-step import-then-replicate — stores go to peers immediately

mediadb (20260403+9) unstable; urgency=medium

  * Remove Local column from cluster status — local node is now a regular peer
  * Fix total_nodes count: no more +1 double-counting

mediadb (20260403+8) unstable; urgency=medium

  * Include local node in peer list — replicate directly to all nodes with parity
  * Remove is_self skip so local paritypp server participates as a regular peer

mediadb (20260403+7) unstable; urgency=medium

  * Fix cluster status: check availability via cluster fetch instead of empty local store
  * local_ok was always false because store_ has no data (no local cache)

mediadb (20260403+6) unstable; urgency=medium

mediadb (20260403+5) unstable; urgency=medium

  * Cluster: write directly to nodes, no local store — replicate and remove via pclient only
  * Fix import: link new media to existing albums (not only new albums)
  * sync_from_cluster always fetches from peers for fresh data

mediadb (20260403+4) unstable; urgency=medium

  * Remove all local paritypp store operations from Cluster (fetch, fetch_from_peers, remove)
  * All data goes exclusively through peers — no local cache reads or writes
  * Simplify sync_from_cluster: single fetch() call (now peers-only)
  * Remove local_ok status from cluster stores API endpoint

mediadb (20260403+2) unstable; urgency=medium

  * Fix intermittent store visibility: use fetch_from_peers in sync (like authdb)
  * Cluster::fetch() returns stale local cache, never checking peers for updates
  * Merge-only index sync: do not delete locally-present stores missing from synced index

 -- Jan Koester <jan.koester@tuxist.de>  Thu, 03 Apr 2026 13:00:00 +0200

mediadb (20260403+1) unstable; urgency=medium

  * Fix store sync ordering: replicate store data before index to prevent stale reads
  * Upgrade cluster_op_mutex_ to shared_mutex for concurrent read access
  * Add shared_lock to all ClusterMediaBackend read methods to prevent reads during sync

mediadb (20260402+5) unstable; urgency=medium

  * Fix race condition: sync_from_cluster could overwrite freshly written data
  * Add cluster_op_mutex_ to serialize all write+replicate operations vs sync

mediadb (20260402+3) unstable; urgency=medium

  * Cluster mode: use paritypp block_store exclusively, no local files
  * Add memory-only BinDb mode for cluster backend
  * Buffer-based serialize/deserialize for index and store data
