add modified time to db header
-------------------------------
Key: COUCHDB-507
URL: https://issues.apache.org/jira/browse/COUCHDB-507
Project: CouchDB
Issue Type: Improvement
Components: Database Core
Affects Versions: 0.11
Reporter: Benoit Chesneau
Attachments: modified.patch
Patch that add modified date to teh db header in view of geeting last time a db
was updated which would allow in case of a global db handler to get all changes
since this date, or just get all new dbs created. Patch is attached and could
be found in my repo :
http://bitbucket.org/benoitc/couchdb/src/9733d08fc7b0/
It works and I can get db infos :
{"db_name":"testdb","doc_count":0,"doc_del_count":1,"update_seq":3,"modified":"1253540241479553","purge_seq":0,"compact_running":false,"disk_size":12398,"instance_start_time":"1253540874651249","disk_format_version":5}
Main problem actually is that it doesn't handle old dbs since header should be
upgraded. I've read the code in couch_file but fail for now to understand the
logic to read/rewrite header. I think I should first test if header is on
version < 0.9 then 0.10 but... Any help would be appreciated.
