Hi, I'm experimenting with a CouchDB setup on a SMB mount point. I know this is not supported, but I ran into a (maybe simple) problem I don't understand. Maybe someone of you can give a hint easily (that would be amazing).
Given the following patch (I need to close/reopen the file descriptors after renaming) for the function https://github.com/apache/couchdb/blob/1.6.x/src/couchdb/couch_db_updater.erl#L176 > 1 --- a/src/couchdb/couch_db_updater.erl > 2 +++ b/src/couchdb/couch_db_updater.erl > 3 @@ -202,8 +202,18 @@ handle_call({compact_done, CompactFilepath}, _From, > #db{filepath=Path}=Db) -> > 4 RootDir = couch_config:get("couchdb", "database_dir", "."), > 5 couch_file:delete(RootDir, Filepath), > 6 ok = file:rename(CompactFilepath, Filepath), > 7 + > 8 + ok = couch_file:close(NewDb#db.updater_fd), > 9 + ok = couch_file:close(NewDb#db.fd), > 10 + {ok, SwappedFd} = couch_file:open(Filepath), > 11 + SwappedReaderFd = open_reader_fd(Filepath, Db#db.options), > 12 + SwappedDb = NewDb2#db{ > 13 + fd = SwappedReaderFd, > 14 + updater_fd = SwappedFd > 15 + }, > 16 + unlink(SwappedFd), > 17 close_db(Db), > 18 - NewDb3 = refresh_validate_doc_funs(NewDb2), > 19 + NewDb3 = refresh_validate_doc_funs(SwappedDb), > 20 ok = gen_server:call(Db#db.main_pid, {db_updated, NewDb3}, > infinity), > 21 couch_db_update_notifier:notify({compacted, NewDb3#db.name}), > 22 ?LOG_INFO("Compaction for db \"~s\" completed.", [Db#db.name]), then the gen_server:call() of line 20 never returns. Is there a major issue with this approach or just a minor mistake in my implementation? Thank you for having a look, Stefan
