Summary: This has several small improvements. benchmark.sh * add BYTES_PER_SYNC as an env variable * use --prepopulate_block_cache when O_DIRECT is used * use --undefok to list options that don't work for all 7.x releases * print "failure" in report.tsv when a benchmark fails * parse the slightly different throughput line used by db_bench for multireadrandom * remove the trailing comma for BlobDB size before printing it in report.tsv * use the last line of the output from /bin/time as there can be more than one line when db_bench has a non-zero exit * fix more bash lint warnings * add ",stats" to the --benchmark=... lines to get stats at the end of each benchmark benchmark_compare.sh * run revrange immediately after fillseq to let compaction debt get removed * add --multiread_batched when --benchmarks=multireadrandom is used * use --benchmarks=overwriteandwait when supported to get a more accurate measure of write-amp Test Plan: Run it for leveled, universal and BlobDB Reviewers: Subscribers: Tasks: Tags:

// Coding guidelines say to avoid static objects with non-trivial destructors,
