2011-01-13Monitor sys_db file descriptor to keep it openAdam Kocoloski
A couch_file process occasionally checks to see if it is being monitored by any clients, and closes if not. Specifically, it checks for at least two monitoring processes, because it assumes couch_stats_collector is one of them. That assumption was wrong for sys_db files, so they would shut down after a minute and need to be reopened. BugzID: 11641
2011-01-07BugzID: 11589 call file:close explicitly to keep VM responsiveRobert Newson
Deleting a large file in the previous scheme has caused the Erlang VM to become unresponsive (including making it drop out of the ring of nodes). The cause of this is currently unknown but Adam discovered that explicitly calling file:close/1 on the file descriptor does not cause this behavior. Accordingly, I have typed in his suggested fix and tested it.

The following block controls the maximum number of OS processes that will be reused. Additional OS processes will still be spawned on-demand, but they'll be terminated when the clients are through with them. [query_server_config] os_process_soft_limit = 100

- Removal of couch_db and couch_ref_counter processes. Active DBs are accessible through a protected ets table owned by couch_server. - #full_doc_info{} in by_id and by_seq trees for faster compaction at the expense of more disk usage afterwards. Proposed as COUCHDB-738 but not accepted upstream. - Replication via distributed Erlang. - Better hot upgrade support (uses exported functions much more often). - Configurable btree chunk sizes allow for larger (but still bounded) reductions. - Shorter names for btree fields in #db{} and #db_header{}. - couch_view_group does not keep a reference to the #db{}. - Terms are stored compressed (again).
