# Path handling for libraries and templates

# Paths have to be normalized because Jinja uses the exact template path to
|
|
# determine the hash used in the cache filename, and we need a pre-caching step
|
|
# to be concurrency-safe. Use absolute path because __file__ is absolute if
|
|
# module is imported, and relative if executed directly.
|
|
# If paths differ between pre-caching and individual file compilation, the cache
|
|
# is regenerated, which causes a race condition and breaks concurrent build,
|
|
# since some compile processes will try to read the partially written cache.
