I've got a CouchDB 2.0 installation, running on Ubuntu 16.04, single node. One particular aspect of my application has write-heavy load, but I want reads need to be timely, so I'm looking to use update_notification to rebuild indexes every n writes.
I created a small NodeJS application to handle this, but found that any time a design document was edited, my server would fall over. This turned out to be because CouchDB was firing up hundreds of copies of the update listener, which in turn seemed to be because of crashes reported in couch.log. Each time there was a crash, a new update listener was spawned, but the old script was not terminating.
I have pared this down to a simple case, where the update_notification hander actually does nothing but log the updates it receives from STDIN:
updates.bash:
#!/bin/bash
while read -r line
do
echo "$line" >> /home/www/logs/updates.log
done
local.ini:
[update_notification]
updates=/home/www/updates.bash
I would expect to see updates.log fill with notifications like...
{"type":"updated","db":"transactions"}
{"type":"ddoc_updated","db":"transactions","id":"_design/temp"}
... and this is what is seen on CouchDB 1.6.1. But on CouchDB 2.0, I see my couch.log populated with hundreds of crash reports, and my update script repeatedly re-spawned.
