major performance improvements in range GETs to avoid large
read amplification when ranges are tiny and random
```

TTFB from 10MiB BlockSize

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
```
* First Access TTFB: Avg: 68ms, Median: 35ms, Best: 11ms, Worst: 1.16s
```

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.
currently when one of the peer is down, the
drives from that peer are reported as '0/0'
offline instead we should capture/filter the
drives from the peer and populate it appropriately
such that `mc admin info` displays correct info.
This commit adds the `FromContentMD5` function to
parse a client-provided content-md5 as ETag.
Further, it also adds multipart ETag computation
for future needs.
prometheus metrics was using total disks instead
of online disk count, when disks were down, this
PR fixes this and also adds a new metric for
total_disk_count
Creating notification events for replica creation
is not particularly useful to send as the notification
event generated at source already includes replication
completion events.
For applications using replica cluster as failover, avoiding
duplicate notifications for replica event will allow seamless
failover.
also re-use storage disks for all `mc admin server info`
calls as well, implement a new LocalStorageInfo() API
call at ObjectLayer to lookup local disks storageInfo
also fixes bugs where there were double calls to StorageInfo()
While starting up a request that needs all IAM data will start another load operation if the first on startup hasn't finished. This slows down both operations.
Block these requests until initial load has completed.
Blocking calls will be ListPolicies, ListUsers, ListServiceAccounts, ListGroups - and the calls that eventually trigger these. These will wait for the initial load to complete.
Fixes issue seen in #11305
Implicit permissions for any user is to be allowed to
change their own password, we need to restrict this
further even if there is an implicit allow for this
scenario - we have to honor Deny statements if they
are specified.
ListObjectVersions would skip past the object in the marker when version id is specified.
Make `listPath` return the object with the marker and truncate it if not needed.
Avoid having to parse unintended objects to find a version marker.
The previous code was iterating over replies from peers and assigning
pool numbers to them, thus missing to add it for the local server.
Fixed by iterating over the server properties of all the servers
including the local one.
There was an io.LimitReader was missing for the 'length'
parameter for ranged requests, that would cause client to
get truncated responses and errors.
fixes#11651
The base profiles contains no valuable data, don't record them.
Reduce block rate by 2 orders of magnitude, should still capture just as valuable data with less CPU strain.
most of the delete calls today spend time in
a blocking operation where multiple calls need
to be recursively sent to delete the objects,
instead we can use rename operation to atomically
move the objects from the namespace to `tmp/.trash`
we can schedule deletion of objects at this
location once in 15, 30mins and we can also add
wait times between each delete operation.
this allows us to make delete's faster as well
less chattier on the drives, each server runs locally
a groutine which would clean this up regularly.
This commit removes the `GetObject` method
from the `ObjectLayer` interface.
The `GetObject` method is not longer used by
the HTTP handlers implementing the high-level
S3 semantics. Instead, they use the `GetObjectNInfo`
method which returns both, an object handle as well
as the object metadata.
Therefore, it is no longer necessary that a concrete
`ObjectLayer` implements `GetObject`.
store the cache in-memory instead of disks to avoid large
write amplifications for list heavy workloads, store in
memory instead and let it auto expire.
This commit replaces the usage of
github.com/minio/sha256-simd with crypto/sha256
of the standard library in all non-performance
critical paths.
This is necessary for FIPS 140-2 compliance which
requires that all crypto. primitives are implemented
by a FIPS-validated module.
Go can use the Google FIPS module. The boringcrypto
branch of the Go standard library uses the BoringSSL
FIPS module to implement crypto. primitives like AES
or SHA256.
We only keep github.com/minio/sha256-simd when computing
the content-SHA256 of an object. Therefore, this commit
relies on a build tag `fips`.
When MinIO is compiled without the `fips` flag it will
use github.com/minio/sha256-simd. When MinIO is compiled
with the fips flag (go build --tags "fips") then MinIO
uses crypto/sha256 to compute the content-SHA256.
