without atomic load() it is possible that for
a slow receiver we would get into a hot-loop, when
logCh is full and there are many incoming callers.
to avoid this as a workaround enable BATCH_SIZE
greater than 100 to ensure that your slow receiver
receives data in bulk to avoid being throttled in
some manner.
this PR however fixes the unprotected access to
the current workers value.
specifying customer HTTP client makes the gcs SDK
ignore the passed credentials, instead let the GCS
SDK manage the transport.
this PR fixes#19922 a regression from #19565
Currently, bucket metadata is being loaded serially inside ListBuckets
Objet API. Fix that by loading the bucket metadata as the number of
erasure sets * 10, which is a good approximation.
When a reconnection happens, `handleMessages` must be able to complete and exit.
This can be prevented in a full queue.

Add a queue cleaner in reconnected that will pop old messages so `handleMessages` can
send messages without blocking and exit appropriately for the connection to be re-established.
Messages are likely dropped by the remote, but we may have some that can succeed,
so we only drop when running out of space.
Add the inlined data as base64 encoded field and try to add a string version if feasible.
Example:
```
λ xl-meta -data xl.meta
{
"8e03504e-1123-4957-b272-7bc53eda0d55": {
"bitrot_valid": true,
"bytes": 58,
"data_base64": "Z29sYW5nLm9yZy94L3N5cyB2MC4xNS4wIC8=",
"data_string": "golang.org/x/sys v0.15.0 /"
}
```
The string will have quotes, newlines escaped to produce valid JSON.
If content isn't valid utf8 or the encoding otherwise fails, only the base64 data will be added.
`-export` can still be used separately to extract the data as files (including bitrot).
* Prevents blocking when losing quorum (standard on cluster restarts).
* Time out to prevent endless buildup. Timed-out remote locks will be canceled because they miss the refresh anyway.
* Reduces latency for all calls since the wall time for the roundtrip to remotes no longer adds to the requests.
since the connection is active, the
response recorder body can grow endlessly
causing leak, as this bytes buffer is
never given back to GC due to an goroutine.
skip healing properly in scanner when drive is hotplugged
due to how the state is passed around the SkipHealing
might not be the true state() of the system always, causing
a situation where we might healing from the scanner on the
same drive which is being. Due to this competing heals get
triggered that slow each other down.
due to a historic bug in CopyObject() where
an inlined object loses its metadata, the
check causes an incorrect fallback verifying
data-dir.
CopyObject() bug was fixed in ffa91f9794 however
the occurrence of this problem is historic, so
the aforementioned check is stretching too much.
Bonus: simplify fileInfoRaw() to read xl.json as well,
also recreate buckets properly.
* Multipart SSEC checksums were not transferred.
* Remove key mismatch logging. This key is user-controlled with SSEC.
* If the source is SSEC and the destination reports ErrSSEEncryptedObject,
assume replication is good.
avoid concurrent callers for LoadUser() to even initiate
object read() requests, if an on-going operation is in progress.
this avoids many callers hitting the drives causing I/O
spikes, also allows for loading credentials faster.
This commit fixes an issue in the KES client configuration
that can cause the following error when connecting to KES:
```
ERROR Failed to connect to KMS: failed to generate data key with KMS key: tls: client certificate is required
```
The Go TLS stack seems to not send a client certificate if it
thinks the client certificate cannot be validated by the peer.
In case of an API key, we don't care about this since we use
public key pinning and the X.509 certificate is just a transport
encoding.
The `GetClientCertificate` seems to be honored always such that
this error does not occur.
Signed-off-by: Andreas Auernhammer <github@aead.dev>
the reason for this is to avoid STS mappings to be
purged without a successful load of other policies,
and all the credentials only loaded successfully
are properly handled.
This also avoids unnecessary cache store which was
implemented earlier for optimization.
