Subject: Add new API method: `getFeedStats'
X-Git-Tag: 1.7.9~25^2~251^2
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=0192ffe5a5f8254d723cf46e4bda839220191c2c;p=tt-rss.git

Add new API method: `getFeedStats'

`getFeedStats' calls the new static function `api_get_feed_stats' to
return an array of real feeds of the following form:

    [{
       "first" : 1127,
       "unread" : 873,
       "last" : 15460,
       "title" : "Some feed",
       "id" : 31,
       "total" : 1513
    }]

where "first", "last", "total" are the first, last and total number of
articles in the feed.

This adds the ability to nntp-oriented clients to efficiently retrieve
an "active file" without having to resort to `getHeadlines(limit=-1)'
