> Project: CouchDB
> Issue Type: Bug
> Components: BigCouch
> Reporter: Alexander Shorin
> Priority: Blocker
> Labels: needs-pr
> Fix For: 2.0.0
>
>
> We have the following code in
> [couch_server|https://github.com/apache/couchdb-couch/blob/master/src/couch_server.erl#L119-L143]
> {code}
> maybe_add_sys_db_callbacks(DbName, Options) when is_binary(DbName) ->
> maybe_add_sys_db_callbacks(?b2l(DbName), Options);
> maybe_add_sys_db_callbacks(DbName, Options) ->
> DbsDbName = config:get("mem3", "shard_db", "dbs"),
> NodesDbName = config:get("mem3", "node_db", "nodes"),
> IsReplicatorDb = DbName == config:get("replicator", "db", "_replicator")
> orelse
> path_ends_with(DbName, <<"_replicator">>),
> IsUsersDb = DbName ==config:get("couch_httpd_auth", "authentication_db",
> "_users") orelse
> path_ends_with(DbName, <<"_users">>),
> if
> DbName == DbsDbName ->
> [sys_db | Options];
> DbName == NodesDbName ->
> [sys_db | Options];
> IsReplicatorDb ->
> [{before_doc_update, fun
> couch_replicator_manager:before_doc_update/2},
> {after_doc_read, fun couch_replicator_manager:after_doc_read/2},
> sys_db | Options];
> IsUsersDb ->
> [{before_doc_update, fun couch_users_db:before_doc_update/2},
> {after_doc_read, fun couch_users_db:after_doc_read/2},
> sys_db | Options];
> true ->
> Options
> end.
> {code}
> Which works perfectly except if system database is clustered. So, for shared
> _users and _replicator the check condition will not work since shared
> databases ends with timestamp and full name looks as
> "shards/00000000-1fffffff/_users.1424979962"
