Each multipart upload is holding a read lock for the entire upload
duration of each part.
This makes it impossible for other parts to complete until all currently
uploading parts have released their locks.
It will also make it impossible for new parts to start as long as the
write lock is still being requested, essentially deadlocking uploads
until all that may have been granted a read lock has been completed.
Refactor to only hold the upload id lock while reading and writing
the metadata, but hold a part id lock while the part is being uploaded.
This commit adds an admin API for fetching
the KMS status information (default key ID, endpoints, ...).
With this commit the server exposes REST endpoint:
```
GET <admin-api>/kms/status
```

Web Handlers can generate STS tokens but forgot to create a parent user
and save it along with the temporary access account. This commit fixes
this.
fixes#12381
its possible that, version might exist on second pool such that
upon deleteBucket() might have deleted the bucket on pool1 successfully
since it doesn't have any objects, undo such operations properly in
all any error scenario.
Also delete bucket metadata from pool layer rather than sets layer.
objectErasureMap in the audit holds information about the objects
involved in the current S3 operation such as pool index, set an index,
and disk endpoints. One user saw a crash due to a concurrent update of
objectErasureMap information. Use sync.Map to prevent a crash.
Always use `GetActualSize` to get the part size, not just when encrypted.
Fixes mint test io.minio.MinioClient.uploadPartCopy,
error "Range specified is not valid for source object".
healing code was using incorrect buffers to heal older
objects with 10MiB erasure blockSize, incorrect calculation
of such buffers can lead to incorrect premature closure of
io.Pipe() during healing.
fixes#12410
- it is possible that during I/O failures we might
leave partially written directories, make sure
we purge them after.
- rename current data-dir (null) versionId only after
the newer xl.meta has been written fully.
- attempt removal once for minioMetaTmpBucket/uuid/
as this folder is empty if all previous operations
were successful, this allows avoiding recursive os.Remove()
- for single pool setups usage is not checked.
- for pools, only check the "set" in which it would be placed.
- keep a minimum number of inodes (when we know it).
- ignore for `.minio.sys`.
It makes sense that a node that has multiple disks starts when one
disk fails, returning an i/o error for example. This commit will make this
faulty tolerance available in this specific use case.
Due to incorrect KMS context constructed, we need to add
additional fallbacks and also fix the original root cause
to fix already migrated deployments.
Bonus remove double migration is avoided in gateway mode
for etcd, instead do it once in iam.Init(), also simplify
the migration by not migrating STS users instead let the
clients regenerate them.
- Adds versioning support for S3 based remote tiers that have versioning
enabled. This ensures that when reading or deleting we specify the specific
version ID of the object. In case of deletion, this is important to ensure that
the object version is actually deleted instead of simply being marked for
deletion.
- Stores the remote object's version id in the tier-journal. Tier-journal file
version is not bumped up as serializing the new struct version is
compatible with old journals without the remote object version id.
- `storageRESTVersion` is bumped up as FileInfo struct now includes a
`TransitionRemoteVersionID` member.
- Azure and GCS support for this feature will be added subsequently.
