Hi all,

I've started today a 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.

Also what do you think of this patch ?
