--------------------------------------
Is this still relevant?
> 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.
