Filipe Manana commented on COUCHDB-1266:
----------------------------------------
Thanks Paul and Adam,
I agree the current status text field could go away, as it can be built from
this stats property. However I would be more confortable doing this change for
2.0 for e.g.
I like to see this in Futon. I agree it currently doesn't look like very
formatted and so on, so it could get polished by someone more confortable with
Futon/CSS/HTML.
About the progress, right now it's trivial to compute (and it's more of an
estimation, without a very high degree of accuracy). But i prefer to leave it's
computation to the tasks and not the applications. This is because how it's
calculated can change in the future as the implementation of the tasks
(compaction, indexing, replication) evolve.
I agree that with setelement and #record.fieldname tricks some code size can be
reduced.

> Project: CouchDB
> Issue Type: Improvement
> Reporter: Filipe Manana

>
> This proposal is simply to add a "stats" field to the _active_tasks results.
> This field can be an arbitrary JSON value and each task can set it to
> whatever is appropriate for it.The following patch also defines some basic
> stats for the existing tasks:
> 1) database compaction - # changes done, total changes, # of revisions
> copied, # of attachments copied and progress (an integer percentage, same as
> what is exposed in the existing text field "status");
> 2) view compaction - # of ids copied, total number of ids, # of kvs copied,
> total number of kvs and progress
> 3) view indexing - # changes done, total changes, # inserted kvs, # deleted
> kvs, progress
> 4) replication - # missing revisions checked, # missing revisions found, #
> docs read, # docs written, # doc write failures, source seq number,
> checkpointed source seq number, progress.
