#!/bin/bash
# The RocksDB regression test script.
# REQUIREMENT: must be able to run make db_bench in the current directory
#
# This script will do the following things in order:
#
# 1. check out the specified rocksdb commit.
# 2. build db_bench using the specified commit
# 3. setup test directory $TEST_PATH. If not specified, then the test directory
# will be "/tmp/rocksdb/regression_test"
# 4. run set of benchmarks on the specified host
# (can be either locally or remotely)
# 5. generate report in the $RESULT_PATH. If RESULT_PATH is not specified,
# RESULT_PATH will be set to $TEST_PATH/current_time
#
# = Examples =
# * Run the regression test using rocksdb commit abcdef that outputs results
# and temp files in "/my/output/dir"
#r
# TEST_PATH=/my/output/dir COMMIT_ID=abcdef ./tools/regression_test.sh
#
# * Run the regression test on a remost host under "/my/output/dir" directory
# and stores the result locally in "/my/benchmark/results" using commit
# abcdef and with the rocksdb options specified in /my/path/to/OPTIONS-012345
# with 1000000000 keys in each benchmark in the regression test where each
# key and value are 100 and 900 bytes respectively:
#
# REMOTE_USER_AT_HOST=yhchiang@my.remote.host \
# TEST_PATH=/my/output/dir \
# RESULT_PATH=/my/benchmark/results \
# COMMIT_ID=abcdef \
# OPTIONS_FILE=/my/path/to/OPTIONS-012345 \
# NUM_KEYS=1000000000 \
# KEY_SIZE=100 \
# VALUE_SIZE=900 \
# ./tools/regression_test.sh
#
# = Regression test environmental parameters =
# DEBUG: If true, then the script will not checkout master and build db_bench
# if db_bench already exists
# Default: 0
# TEST_PATH: the root directory of the regression test.
# Default: "/tmp/rocksdb/regression_test"
# RESULT_PATH: the directory where the regression results will be generated.
# Default: "$TEST_PATH/current_time"
# REMOTE_USER_AT_HOST: If set, then test will run on the specified host under
# TEST_PATH directory and outputs test results locally in RESULT_PATH
# The REMOTE_USER_AT_HOST should follow the format user-id@host.name
# DB_PATH: the path where the rocksdb database will be created during the
# regression test. Default: $TEST_PATH/db
# WAL_PATH: the path where the rocksdb WAL will be outputed.
# Default: $TEST_PATH/wal
# OPTIONS_FILE: If specified, then the regression test will use the specified
# file to initialize the RocksDB options in its benchmarks. Note that
# this feature only work for commits after 88acd93 or rocksdb version
# later than 4.9.
# DELETE_TEST_PATH: If true, then the test directory will be deleted
# after the script ends.
# Default: 0
#
# = db_bench parameters =
# NUM_THREADS: The number of concurrent foreground threads that will issue
# database operations in the benchmark. Default: 16.
# NUM_KEYS: The key range that will be used in the entire regression test.
# Default: 1G.
# NUM_OPS: The number of operations (reads, writes, or deletes) that will
# be issued in EACH thread.
# Default: $NUM_KEYS / $NUM_THREADS
# KEY_SIZE: The size of each key in bytes in db_bench. Default: 100.
# VALUE_SIZE: The size of each value in bytes in db_bench. Default: 900.
# CACHE_SIZE: The size of RocksDB block cache used in db_bench. Default: 1G
# STATISTICS: If 1, then statistics is on in db_bench. Default: 0.
# COMPRESSION_RATIO: The compression ratio of the key generated in db_bench.
# Default: 0.5.
# HISTOGRAM: If 1, then the histogram feature on performance feature is on.
# STATS_PER_INTERVAL: If 1, then the statistics will be reported for every
# STATS_INTERVAL_SECONDS seconds. Default 1.
# STATS_INTERVAL_SECONDS: If STATS_PER_INTERVAL is set to 1, then statistics
# will be reported for every STATS_INTERVAL_SECONDS. Default 60.
# MAX_BACKGROUND_FLUSHES: The maxinum number of concurrent flushes in
# db_bench. Default: 4.
# MAX_BACKGROUND_COMPACTIONS: The maximum number of concurrent compactions
# in db_bench. Default: 16.
# SEEK_NEXTS: Controls how many Next() will be called after seek.
# Default: 10.
# SEED: random seed that controls the randomness of the benchmark.
# Default: $( date +%s )
