CouchDB API query with ?limit=0 returns one row - bug or feature? -


i use couchdb 1.5.0 , noticed strange thing:

when query api action, example:

curl -x "http://localhost:5984/mydb/_changes?limit=1"

i same result limit=1 , limit=0 , limit=-55. in cases 1 row start of list.

although, postgresql returns:

  • zero rows when limit 0
  • message error: limit must not negative when limit -55

my question concerned api design. know opinions.

it's flaw or maybe it's good/acceptable practice?

this how _changes api designed. if not specify type of feed i.e long-poll, continuous etc default return list of changes in single results array.

if want row row result of changes in database specify type of feed in url so

curl -x "http://localhost:5984/mydb/_changes?feed=continuous"

another point note in _changes api using 0 has same effect using 1 in limit parameter.
