All,
Please ignore my last paragraph ............ I was able to replicate my
own stupidity ......... everything on the changes feed is as expected.
very best regards

All,
Gave things a little time to settle down following the data loss issue
but checked out trunk from svn this morning and tested the versioning
technique outlined by Chris below........ it works "luvly" and fits my
purposes perfectly.
As an aside, following my initial reluctance to use the changes feed
as an audit trail (mainly due to laziness on my part since I did not
want the rigmarole of new addition to the design file etc) I wrote a
node script as a simple logger.
One thing that I have noticed is that you get an entry in the changes
feed if you upload an attachment but no entry if an attachment is
deleted. Is this expected behaviour?.
Very Best Regards
Cliff

tks for explanation ......... all clear in my head now.

That's just perfect for validation. Appreciate the link.
FYI there's a minor JavaScript bug in 1.0.0 that prevent the
versioning technique in that article from working out of the box. The
bug has been fixed in trunk and the 1.0.x branch, and the fix will be
in the 1.0.1 release which is coming out this week.
Chris
Thank you all for your help
very best regards

For your use case you might look at these versioning techniques:

the changes feed only shows the update sequences for the current
documents

documents
because they will go away after compaction anyway.
every time a document is updated it removes it's previous sequence
from the
by-sequence index and the revision information is only available
by querying
for it on the document itself (until you compact).

All,
Good afternoon.
using this url
http://10.0.0.10:5984/test/_changes?since=14966&all_docs=true
I get the following results
{"results":[

now if I make an amendment to the document at sequence number
15006 and
using the same URL I get the following results.

I think that it is fairly straight forward to ascertain that we
are looking
at latest revision sequences.
Is there a way to see all sequence numbers?? I am of course aware
of the
continuous feed but do not wish to use it.
My use case is for a pharma regulated clinical trials database
where i need
a total audit of every single change made to the database.
best regards
Cliff
