Jyrki Pulliainen updated COUCHDB-743:
-------------------------------------
Description:
When using HTTP PUT to store attachments the request takes exactly one second
to finish when the attachment size is 1025 bytes or more. This behaviour does
not occur with inline attachments.
Here's a bash script to reproduce the behaviour (requires curl and python >=
2.6)
#!/bin/sh
size=1025
curl -X DELETE http://localhost:5984/test
curl -X PUT http://localhost:5984/test
docid=0
while true; do
rev=`curl -s -X PUT http://localhost:5984/test/$docid --data-binary '{}' |
python -c "import json; import sys; print json.load(sys.stdin)['rev']"`
echo -n "start:"; date '+%H:%M:%S.%N'
head -c $size /dev/urandom | curl -s -X PUT -H 'Content-Type: text/plain'
http://localhost:5984/test/$docid/attachment\?rev=$rev --data-binary @-
echo -n "end:"; date '+%H:%M:%S.%N'
docid=$(($docid+1))
done
