Benoit Chesneau closed COUCHDB-507.
-----------------------------------

    Resolution: Later

nope, I think a better implementation of that concept should be done. Will revisit that when I have some time. Closing it for now.

> 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.
