Benchmarking and build commands are run with the following environment variables available:
ASV: true
ASV_PROJECT: the project name from the configuration file
ASV_ENV_NAME: name of the currently active environment
ASV_ENV_TYPE: type of the currently active environment
ASV_ENV_DIR: full path to the currently active environment root
ASV_CONF_DIR: full path to the directory where asv.conf.json is
ASV_BUILD_DIR: full path to the build directory (checked-out source path + repo_subdir)
ASV_BUILD_CACHE_DIR: full path to the build cache directory
ASV_COMMIT: commit hash of currently installed project
If there is no asv-managed environment, build, or cache directory, or commit hash, those environment variables are unset.
The following environment variables controlling Python and other behavior are also set:
PATH: environment-specific binary directories prepended
PIP_USER: false
PYTHONNOUSERSITE: True (for conda environments only)
PYTHONPATH: unset (if really needed, can be overridden by setting ASV_PYTHONPATH)
