Two coupled changes that must land together, because the same files carry both:
the server now identifies itself as Silo, and every path that would have called
home to a MinIO-operated service is closed.
Product identity
- build-constants.go: store name, UA name and startup banner become Silo. The
Go identifiers (MinioStoreName, MinioBannerName, ...) keep their names on
purpose - renaming exported symbols would churn the compatibility surface for
a cosmetic gain, and the rebrand guard freezes that surface.
- main.go, server-startup-msg.go, ftp-server.go and the user-visible log, help
and error strings across cmd/ and internal/ switch to Silo. Original MinIO
copyright, LICENSE, NOTICE and CREDITS are untouched; --version now prints
the upstream copyright, the pgsty modification notice, and the trademark
policy's approved "based on MinIO technology" attribution.
- api-headers.go: the HTTP Server header becomes "Silo". This is the one
externally observable identity change, so TestCommonHeadersUseSiloProductName
pins it - probes that sniff for "MinIO" must move to capability detection.
- Prometheus metric HELP strings keep their MinIO wording. They are part of the
metrics contract the guard protects, not product copy.
Configuration directory
- config-dir.go: new installs use ~/.silo. If only ~/.minio exists it is still
read, with a one-time notice and no files moved. If both exist ~/.silo wins
and an ambiguity warning is emitted; an explicit --config-dir always wins.
Covered by TestSelectDefaultConfigDir. The internal .minio.sys layout is
never renamed - this rule applies to the user config directory only.
Upstream service lockdown
- globalInplaceUpdateDisabled is now true at initialization rather than being
set from MINIO_UPDATE. common-main.go still parses MINIO_UPDATE so upgrading
nodes do not fail on an unknown key, but warns that the value is ignored;
there is no way to re-enable the updater. TestInplaceUpdateCannotBeEnabled
guards that. Without this, an admin with mc could have overwritten
/usr/bin/silo with an upstream MinIO binary.
- verifyBinary and commitBinary refuse early; the ServerUpdate v1/v2 admin
routes and the peer-rest update endpoints stay registered and keep returning
the existing programmatic error, so clients see a stable failure rather than
a 404.
- MinioReleaseBaseURL and defaultMinisignPubkey are emptied: no dl.min.io
download root, and upstream's minisign key is no longer a trust root for
anything this fork ships.
- cmd/callhome.go is deleted and internal/config/subnet/ is reduced to parsing
its old keys and reporting that the integration is disabled. config-current.go
warns instead of failing when callhome or SUBNET settings are present, so an
upgraded node with those keys still starts.
- internal/config/errors.go replaces the MinIO Slack and support entry points
with Silo documentation and issue links. Error codes and programmatic fields
are unchanged.
Verified: the compatibility baseline is unchanged except for the deliberate
removal of the /api/health/upload SUBNET route; go build, go vet and the full
cmd/ and internal/ unit suites pass; a locally built binary starts, serves
S3/Admin/metrics on the unchanged /minio/* routes, answers with Server: Silo,
and falls back to a pre-existing ~/.minio with the expected notice.

The discrete PostgreSQL connection path concatenated raw values into a libpq keyword/value string. Whitespace, quotes, or backslashes could split a value into additional parameters or make an otherwise valid configuration fail to parse; the path also used the unsupported keyword username instead of user.
Render every generated value as a single-quoted libpq parameter, escape quotes and backslashes, and use the correct user key. Keep the existing connection_string form untouched. The earlier attempt to register migrated PostgreSQL and MySQL fields is deliberately absent because those key names collide with the legacy connection-string tokenizer.
Focused tests cover ordinary values, whitespace, quotes, backslashes, and parameter-shaped input.

GetNotifyNATS reads user_credentials, nkey_seed and tls_handshake_first
and GetNotifyAMQP reads immediate, but none of them were registered in
DefaultNATSKVS/DefaultAMQPKVS or the help schema, so CheckValidKeys
rejected any enable=on target carrying them. Worse, the legacy config
migration wrote exactly these keys - including the env var name
MINIO_NOTIFY_NATS_USER_CREDENTIALS used as a config key, because the
NATSUserCredentials constant doubled as both - so a migrated NATS config
failed validation on every load, and the FetchEnabledTargets fail-fast
then silently disabled all bucket notification targets.
- Register user_credentials/nkey_seed/tls_handshake_first (NATS) and
immediate (AMQP) in the default KVS and help schema; split
NATSUserCredentials into a real config key plus EnvNATSUserCredentials
(all env var names byte-stable)
- Fix legacy migration: SetNotifyNATS writes the proper key;
SetNotifyAMQP no longer writes cfg.Immediate under the internal key
and now carries both immediate and internal
- Tolerate the legacy MINIO_NOTIFY_NATS_USER_CREDENTIALS key written by
pre-fix migrations (NATS-scoped, load path only) with fallback read;
env > user_credentials > legacy key
- Print key names only, never values, in the invalid-keys error of both
CheckValidKeys forms; rejected values can carry credentials
- Add an AST-based audit test asserting parser reads, migration writes
and help entries stay within the registered key set for all ten notify
subsystems, with floor assertions so collector drift fails loudly
- Document (unchanged) FetchEnabledTargets fail-fast and pin it with a
characterization test
Known same-class gap left in place and pinned by the audit's allowlist:
SetNotifyPostgres/SetNotifyMySQL write five unregistered DSN-era keys;
tracked for a follow-up issue.

`go generate ./...` ran afterwards to keep generated.
The items will be saved per target batch and will
be committed to the queue store when the batch is full
Also, periodically commit the batched items to the queue store
based on configured commit_timeout; default is 30s;
Bonus: compress queue store multi writes
This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.
replace io.Discard usage to fix NUMA copy() latencies
On NUMA systems copying from 8K buffer allocated via
io.Discard leads to large latency build-up for every
```
copy(new8kbuf, largebuf)
```
can in-cur upto 1ms worth of latencies on NUMA systems
due to memory sharding across NUMA nodes.
fixes#15334
- re-use net/url parsed value for http.Request{}
- remove gosimple, structcheck and unusued due to https://github.com/golangci/golangci-lint/issues/2649
- unwrapErrs upto leafErr to ensure that we store exactly the correct errors
