Makefile

# The TiKV Makefile
#
# These are mostly light rules around cargo and in general developers
# can do daily development using cargo alone. It does do a few key
# things that developers need to understand:
#
# It turns on features that are not on by default in the cargo
# manifest but that are part of the release build (see the
# ENABLE_FEATURES variable).
#
# The `clippy` rule runs clippy with custom configuration, so
# is the correct way to run clippy against TiKV.
#
# The `test` rule runs tests in configurations that are not covered by `cargo
# test` by default.
#
# Important make rules:
#
# - `build` - create a development profile, unoptimized build
#
# - `run` - run a development build
#
# - `test` - run the test suite in a variety of configurations
#
# - `format` - reformat the code with cargo format
#
# - `clippy` - run clippy with tikv-specific configuration
#
# - `dev` - the rule that needs to pass before submitting a PR. It runs
#   tests and static analysis including clippy and rustfmt
#
# - `release` - create a release profile, optimized build

# So we use cargo `config-profile` feature to specify profiles in
# `.cargo/config`, which `scripts/run-cargo.sh copies into place.
#
# Presently the only thing this is used for is the `dist_release`
# rules, which are used for producing release builds.
