sleep $((120 + ($RANDOM % 1800)))
curl -s http://localhost:8986/solr/{ar,en,es,fr,pt,ru,zh}/update -H 'Content-Type: text/xml' --data-binary '<commit waitSearcher="true"/>'
curl -s http://localhost:8986/solr/{ar,en,es,fr,pt,ru,zh}/update -H "Content-Type: text/xml" --data-binary '<optimize/>'
#!/bin/sh
set -eu
# Test whether Solr is up several times to avoid race conditions when Solr is
# starting up or very busy (i.e. rebuilding & optimizing the index)
for i in `seq 1 15`; do
curl -o /dev/null --silent --fail --show-error 'http://127.0.0.1:8986/solr/en/admin/ping' && exit 0
sleep 1
done
logger -s -t wdl-solr-watchdog "Solr is unresponsive. Attempting to restart..."
# Ensure that the permissions have not been clobbered by another task and that the directory
# has not been removed:
install -d -m 0755 /opt/wdl/solr/work
# We rely on Upstart to restart Solr after it exists.
pkill -n -f wdl/solr
