Subject [jira] Reopened: (COUCHDB-84) Reduce with group=true and count set to less than the # of returned rows, fails to close the json array
Date Fri, 25 Jul 2008 18:27:32 GMT

]

Chris Anderson reopened COUCHDB-84:
-----------------------------------


The old fix continues to calculate the group reduce view long after the count has been reached.
This new patch makes these queries MUCH faster, as well as fixing a potential invalid JSON
response on very large data sets.

> Running a request with group=true and a count which limits the amount of rows returned,
results in invalid JSON (and a 500 error being logged by CouchDB). The problems has been reproduced
in a test case attached to this ticket.
> The fix may be a little iffy (I changed some code that was probably like it was for a
reason...) so please review before applying the patch.
