Idea #21020
Updated by Brett Smith 11 months ago
We should support "XDG Base Directory environment variables":https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html throughout the Python SDK. Things like @XDG_CONFIG_PATH@ and @XDG_CACHE_HOME@. Note that this includes validations like ensuring the paths are absolute. There are probably packages on PyPI that can help us with this.
Known specific instances:
* @arvados.config.initialize@ should default to @config_file=None@. When the value is @None@, the function should search @XDG_CONFIG_PATH@ to find @arvados/settings.conf@.
* @arvados.api.http_cache@ should create and write to to @$XDG_CACHE_HOME/arvados/SUBDIR@.
* <pre>$ git grep -Fe .cache -e .config --line-number sdk/python/ sdk/cwl/ services/fuse/ services/dockercleaner/ tools/user-activity/ tools/crunchstat-summary/
