Every test that starts a database hashed the bootstrap admin password
with Argon2id at 64 MB, which under -race holds about 150 MB per hash,
across dozens of parallel tests. HashPassword now hashes at 1 MB when
testing.Testing() reports a test binary, so every test package gets
the lower cost and a binary built by go build never does. One test
still hashes and verifies through HashPassword at the shipped
parameters, which are unchanged.
script/test also runs at most four packages and eight parallel tests
at once: unbounded, a many-core host linked and ran every test binary
together.
