Add TTFB for all requests in metrics-v3 in addition to the existing
GetObject. Also for the requests that do not return a body in the
response, calculate TTFB as the HTTP status code and the headers are
sent.
Tests if imported service accounts have
required access to buckets and objects.

this cache will be honored only when `prefix=""` while
performing ListMultipartUploads() operation.
This is mainly to satisfy applications like alluxio
for their underfs implementation and tests.

AFAICT we send a canceled context to unlock (and thereby releaseAll). This will cause network calls to fail.
Instead use background and add 30s timeout.
Current implementation retries forever until our
log buffer is full, and we start dropping events.
This PR allows you to set a value until we give
up on existing audit/logger batches to proceed to
process the new ones.
Bonus:
- do not blow up buffers beyond batchSize value
- do not leak the ticker if the worker returns
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
S3 spec does not accept an ILM XML document containing both <Filter>
and <Prefix> XML tags, even if both are empty. That is why we added
a 'set' field in some lifecycle structures to decide when and when not to
show a tag. However, we forgot to disallow marshaling of Filter when
'set' is set to false.
This will fix ILM document replication in a site replication
configuration in some cases.
Services are unfrozen before `initBackgroundReplication` is finished. This means that
the globalReplicationStats write is racy. Switch to an atomic pointer.
Provide the `ReplicationPool` with the stats, so it doesn't have to be grabbed
from the atomic pointer on every use.
All other loads and checks are nil, and calls return empty values when stats
still haven't been initialized.
move away from map[string]interface{} to map[string]string
to simplify the audit, and also provide concise information.
avoids large allocations under load(), reduces the amount
of audit information generated, as the current implementation
was a bit free-form. instead all datastructures must be
flattened.
- optimize writing part.N.meta by writing both part.N
and its meta in sequence without network component.
- remove part.N.meta, part.N which were partially success
ful, in quorum loss situations during renamePart()
- allow for strict read quorum check arbitrated via ETag
for the given part number, this makes it double safer
upon final commit.
- return an appropriate error when read quorum is missing,
instead of returning InvalidPart{}, which is non-retryable
error. This kind of situation can happen when many
nodes are going offline in rotation, an example of such
a restart() behavior is statefulset updates in k8s.

This commit replaces the LDAP client TLS config and
adds a custom list of TLS cipher suites which support
RSA key exchange (RSA kex).
Some LDAP server connections experience a significant slowdown
when these cipher suites are not available. The Go TLS stack
disables them by default. (Can be enabled via GODEBUG=tlsrsakex=1).
fixes https://github.com/minio/minio/issues/20214
With a custom list of TLS ciphers, Go can pick the TLS RSA key-exchange
cipher. Ref:
```
if c.CipherSuites != nil {
return c.CipherSuites
}
if tlsrsakex.Value() == "1" {
return defaultCipherSuitesWithRSAKex
}
```

epoll contention on TCP causes latency build-up when
we have high volume ingress. This PR is an attempt to
relieve this pressure.
upstream issue https://github.com/golang/go/issues/65064
It seems to be a deeper problem; haven't yet tried the fix
provide in this issue, but however this change without
changing the compiler helps.
Of course, this is a workaround for now, hoping for a
more comprehensive fix from Go runtime.
the main reason is to let Go net/http perform necessary
book keeping properly, and in essential from consistency
point of view its GETs all the way.
Deprecate sendFile() as its buggy inside Go runtime.
allow non-inlined on disk to be inlined via
an unversioned ReadVersion() call, we only
need ReadXL() to resolve objects with multiple
versions only.
The choice of this block makes it to be dynamic
and chosen by the user via `mc admin config set`
Other bonus things
- Start measuring internode TTFB performance.
- Set TCP_NODELAY, TCP_CORK for low latency
Use `runtime.Gosched()` if we have less than maxMergeMessages and the
queue is empty. Up maxMergeMessages to 50 to merge more messages into
a single write.
Add length check for an early bailout on readAllInto when we know packet length.
This commit enforces FIPS-compliant TLS ciphers in FIPS mode
by importing the `fipsonly` module.
Otherwise, MinIO still accepts non-FIPS compliant TLS connections.
removes contentious usage of mutexes in LRU, which
were never really reused in any manner; we do not
need it.
To trust hosts, the correct way is TLS certs; this PR completely
removes this dependency, which has never been useful.

Bonus: use `x-minio-time` as a nanosecond to avoid unnecessary
parsing logic of time strings instead of using a more
straightforward mechanism.
Split the read and write sides of handleMessages into two separate functions
Cosmetic. The only non-copy-and-paste change is that `cancel(ErrDisconnected)` is moved
into the defer on `readStream`.
