In the Dockerfile test phase, internal/vaultik spent 23.6s of 31.9s in
36 tests run one at a time. 24 of them were serial only because they
call log.Initialize; they now call it before t.Parallel(), so the
logger is replaced before any parallel test runs. The 12 still serial
change the umask, TMPDIR, os.Stderr or time.Local.
TestLargeDatasets took 8.4s of the 9.8s internal/database run by
committing each of its 1,500 inserts on its own; it now makes them in
one transaction. TestDedupOnlySnapshotRestores gives its second backup
its own snapshot name instead of sleeping 1.1s for a new snapshot ID.
Model: opus-5-5
A backup without --cron of a snapshot with two or more paths panicked
with "close of closed channel". Scan runs once per path, and it started
the progress reporter and deferred its Stop each time; Stop closes the
reporter's signal channel, so the second path's Stop panicked.
scanAllDirectories now starts the reporter before the first path and
stops it after the last, and Scan no longer starts or stops it. A new
test backs up a two-path snapshot with the reporter on and restores
both paths.
