# DEBUG_LEVEL can have three values:
# * DEBUG_LEVEL=2; this is the ultimate debug mode. It will compile rocksdb
# without any optimizations. To compile with level 2, issue `make dbg`
# * DEBUG_LEVEL=1; debug level 1 enables all assertions and debug code, but
# compiles rocksdb with -O2 optimizations. this is the default debug level.
# `make all` or `make <binary_target>` compile RocksDB with debug level 1.
# We use this debug level when developing RocksDB.
# * DEBUG_LEVEL=0; this is the debug level we use for release. If you're
# running rocksdb in production you most definitely want to compile RocksDB
# with debug level 0. To compile with level 0, run `make shared_lib`,
# `make install-shared`, `make static_lib`, `make install-static` or
# `make install`

# Run all tests in parallel, accumulating per-test logs in t/log-*.
#
# Each t/run-* file is a tiny generated bourne shell script that invokes one of
# sub-tests. Why use a file for this?  Because that makes the invocation of
# parallel below simpler, which in turn makes the parsing of parallel's
# LOG simpler (the latter is for live monitoring as parallel
# tests run).
#
# Test names are extracted by running tests with --gtest_list_tests.
# This filter removes the "#"-introduced comments, and expands to
# fully-qualified names by changing input like this:
#
#   DBTest.
#     Empty
#     WriteEmptyBatch
#   MultiThreaded/MultiThreadedDBTest.
