The test and verification scripts invoked ./minio and pulled their tooling from
upstream infrastructure with no integrity check. Every `curl | tar` of a client
or an old server binary was an unverified execution path in a script that
regularly runs as a privileged user, and several fetched a floating "latest".
Two installers replace all of it:
- install-mcli.sh resolves a pinned pgsty/mc release, downloads the archive and
its checksum manifest, requires exactly one valid manifest entry for the
asset, verifies it, and installs. MCLI_BIN with a mandatory MCLI_SHA256 lets
an offline or air-gapped run supply its own binary, still checksum-checked.
- install-verified-fixture.sh takes source, expected SHA-256 and target, and
refuses anything that does not match. Sources may be a URL or a local file.
Every script that previously downloaded mc now calls install-mcli.sh. The three
places that genuinely need an upstream artifact - the old MinIO server binary
for the LDAP IAM upgrade-import test, the 2021 mc for the three-site
replication test, and the functional-tests.sh fixture - go through
install-verified-fixture.sh with the digest recorded inline. Those dl.min.io
URLs remain on purpose: they are historical upstream artifacts needed to prove
upgrade compatibility, and they are now pinned and verified rather than
trusted.
The scripts otherwise switch to ./silo, silo.service, the silo container and
compose service names, and SILO_CONFIG_DIR. run-multi-site-minio-idp.sh is
renamed to run-multi-site-silo-idp.sh with the Makefile target following.
buildscripts/minio-upgrade.sh keeps its name and its `minio server` argv - it
exists to test the MinIO-to-Silo upgrade, so the old side must stay old - but
it is now pinned to an image digest rather than a tag, and its `docker system
prune` and `docker volume prune` calls are removed. Those ran unfiltered
against the developer's whole Docker installation; the resiliency tests had the
same problem and lose their prune and `docker ps -q` sweeps too.

without atomic load() it is possible that for
a slow receiver we would get into a hot-loop, when
logCh is full and there are many incoming callers.
to avoid this as a workaround enable BATCH_SIZE
greater than 100 to ensure that your slow receiver
receives data in bulk to avoid being throttled in
some manner.
this PR however fixes the unprotected access to
the current workers value.
