This PR adds CopyObject support for objects residing in buckets
in different Minio instances (where Minio instances are part of
a federated setup).
Also, added support for multiple Minio domain IPs. This is required
for distributed deployments, where one deployment may have multiple
nodes, each with a different public IP.
Buckets already present on a Minio server before it joins a
bucket federated deployment will now be added to etcd during
startup. In case of a bucket name collision, admin is informed
via Minio server console message.
Added configuration migration for configuration stored in etcd
backend.
Also, environment variables are updated and ListBucket path style
request is no longer forwarded.
Minio server supports healthcheck and prometheus related
unauthenticated endpoints. This document summarizes this
information in a single place and add links for more detailed
documentation if needed.
This change disables the non-constant-time implementations of P-384 and P-521.
As a consequence a client using just these curves cannot connect to the server.
This should be no real issues because (all) clients at least support P-256.
Further this change also rejects ECDSA private keys of P-384 and P-521.
While non-constant-time implementations for the ECDHE exchange don't expose an
obvious vulnerability, using P-384 or P-521 keys for the ECDSA signature may allow
pratical timing attacks.
Fixes#5844
This PR adds disk based edge caching support for minio server.
Cache settings can be configured in config.json to take list of disk drives,
cache expiry in days and file patterns to exclude from cache or via environment
variables MINIO_CACHE_DRIVES, MINIO_CACHE_EXCLUDE and MINIO_CACHE_EXPIRY
Design assumes that Atime support is enabled and the list of cache drives is
fixed.
- Objects are cached on both GET and PUT/POST operations.
- Expiry is used as hint to evict older entries from cache, or if 80% of cache
capacity is filled.
- When object storage backend is down, GET, LIST and HEAD operations fetch
object seamlessly from cache.
Current Limitations
- Bucket policies are not cached, so anonymous operations are not supported in
offline mode.
- Objects are distributed using deterministic hashing among list of cache
drives specified.If one or more drives go offline, or cache drive
configuration is altered - performance could degrade to linear lookup.
Fixes#4026
- removes backend/{fs,xl} files.
- removes FreeBSD doc since we already have FreeNAS doc.
- removes sets/ directory which is redundant with
large-bucket directory.
- removes browser/ directory which attempts
to explain about browser RPC calls, since
its an internal API we do not need to document it.
