Running python -m sir reindex doesn't always return in musicbrainz-docker.

It never happened in production using nohup.

Steps to reproduce

Install musicbrainz-docker@rmq-sir-solr (related PR) and run as follows:

git clone -b rmq-sir-solr https://github.com/yvanzo/musicbrainz-docker.git
cd musicbrainz-docker
export COMPOSE_FILE=docker-compose.yml:docker-compose.public.yml:docker-compose.musicbrainz-development.yml
docker-compose up -d
docker-compose exec musicbrainz /createdb.sh -fetch -sample

Log files

SIR has a debug option but no logging option, its stdout must be captured:

docker-compose exec indexer python -m sir -d reindex \
> reindex-`date -u -Iseconds`.debug.log

Solr has logs that can be more useful to check for activity:

docker-compose logs search

Indexes status

Search indexes can be rebuilt for a specific entity type ~ core as follows:

entity_type=annotation
docker-compose exec indexer python -m sir -d reindex --entity-type ${entity_type} \
> reindex-${entity_type}-`date -u -Iseconds`.debug.log

Indexes completion can be checked by comparing for each entity-type ~ core:

• numDocs in core index at http://localhost:8983/solr/#/~cores
• number of entries in the corresponding table

  entity_type=annotation
  docker-compose exec db psql -U musicbrainz -d musicbrainz_db \
  -c "COPY(SELECT COUNT(*) FROM ${entity_type}) TO STDOUT"
