# Prints the hash that names CI's framework cache directory for a build of zip-builder.
|
|
#
|
|
# Usage: tool_hash.sh [commit] (default: HEAD)
|
|
#
|
|
# Fingerprints don't cover the tool's own code, so CI keeps a cache directory per tool build. Only
|
|
# the code that can change a built framework without changing its fingerprint counts: generating
|
|
# and building the project (Building/), how the model is written into it (Model/), and the
|
|
# XcodeProj version (Package.resolved). Everything else is already covered:
|
|
# - planning and customizing produce the plan, which every fingerprint hashes;
|
|
# - FrameworkCache.swift computes the fingerprints, so changing it changes the keys;
|
|
# - Layout.swift, packaging, verify, diff and the commands run after the cache.
|
|
# When code outside these paths starts to shape built frameworks, add it here.
