For operations that require the object to exist make it possible to
detect if the file isn't found in *any* pool.
This will allow these to return the error early without having to re-check.
Cases where we have applications making request
for `//` in object names make sure that all
are normalized to `/` and all such requests that
are prefixed '/' are removed. To ensure a
consistent view from all operations.
Some deployments have low parity (EC:2), but we really do not need to
save our config data with the same parity configuration.
N/2 would be better to keep MinIO configurations intact when unexpected
a number of drives fail.
This commit disables the Hashicorp Vault
support but provides a way to temp. enable
it via the `MINIO_KMS_VAULT_DEPRECATION=off`
Vault support has been deprecated long ago
and this commit just requires users to take
action if they maintain a Vault integration.
This commit adds FIPS-specifc build tags to the madmin
package. When madmin is compiled with `--tags "fips"`
it will always use AES-GCM for encryption - not just
when an optimized AES implementation is available.
major performance improvements in range GETs to avoid large
read amplification when ranges are tiny and random

Full object reads however do see a slight change which won't be
noticeable in real world, so not doing any comparisons
TTFB still had improvements with full object reads with 1MiB
```

This change should affect all new uploads, previous uploads should
continue to work with business as usual. But dramatic improvements can
be seen with these changes.
A group can have multiple policies, a user subscribed to readwrite &
diagnostics can perform S3 operations & admin operations as well.
However, the current code only returns one policy for one group.
This commit disables SHA-3 for OpenID when building a
FIPS-140 2 compatible binary. While SHA-3 is a
crypto. hash function accepted by NIST there is no
FIPS-140 2 compliant implementation available when
using the boringcrypto Go branch.
Therefore, SHA-3 must not be used when building
a FIPS-140 2 binary.
* Provide information on *actively* healing, buckets healed/queued, objects healed/failed.
* Add concurrent healing of multiple sets (typically on startup).
* Add bucket level resume, so restarts will only heal non-healed buckets.
* Print summary after healing a disk is done.
