| # Checks that that redis is already installed, and then runs it on |
| # random port with temporary working directory. Port is saved in $REDIS_PORT env |
| # variable. Commands in $@ (e.g. a test binary) are then run and server is then |
| # shut down and temporary directory is deleted in the end. These commands are |
| # run using builtin eval, so be careful and enjoy variable substitutions and |
| # invoking several commands under same server. It's useful if you want to run |
| # tests twice: once with cold-cache and once with warm-cache. |
| # |
| # Redis is configured to store no more than 1GB of data and will evict some keys |
| # when it needs more memory. |
| # |
| # Example (mind single quotes in the second command so substitution is |
| # performed inside the script, not when you run it): |
| # ../run_program_with_redis.sh \ |
| # echo Starting client \; \ |
| # redis-cli '$REDIS_PORT' |
| |
| set -e |
| set -u |
| |
| # Start redis on random port and put log in <workdir>/redis.log |
| source $(dirname "$BASH_SOURCE")/start_background_server.sh \ |
| redis-server \ |
| --bind localhost \ |
| --port '$SERVER_PORT' \ |
| --dir '$SERVER_WORKDIR' \ |
| --logfile 'redis.log' \ |
