- remove targetClient for passing around via replicationObjectInfo{}
- remove cloing to object info unnecessarily
- remove objectInfo from replicationObjectInfo{} (only require necessary fields)
given a versionId the mtime is always the same, it
can never be different than its original value.
versionIds also do not conflict, since they are uuid's
and unique practically forever.
Bonus fixes include
- do not have to write final xl.meta (renameData) does this
already, saves some IOPs.
- make sure to purge the multipart directory properly using
a recursive delete, otherwise this can easily pile up and
rely on the stale uploads cleanup.
fixes#17863
sending whitespace character with CompleteMultipartUpload()
with 200 OK was an AWS S3 compatible implementation detail,
and it was expected that the client SDK must look for both
successful XML as well as error XML for 200 OK.
But this is not useful anymore on MinIO, since we do not
have any large delayed coalescing of parts anymore.
- look for requested encryption while compressing
not just via HTTP Headers, but also via multipart
metadata
- look for SSE-S3 etag decryption not just via HTTP
Headers, but also via multipart metadata
fixes#17519
- lifecycle must return InvalidArgument for rule errors
- do not return `null` versionId in HTTP header
- reject mixed SSE uploads with correct error message
PUT shall only proceed if pre-conditions are met, the new
code uses
- x-minio-source-mtime
- x-minio-source-etag
to verify if the object indeed needs to be replicated
or not, allowing us to avoid StatObject() call.
Do completely independent multipart uploads.
In distributed mode, a lock was held to merge each multipart
upload as it was added. This lock was highly contested and
retries are expensive (timewise) in distributed mode.
Instead, each part adds its metadata information uniquely.
This eliminates the per object lock required for each to merge.
The metadata is read back and merged by "CompleteMultipartUpload"
without locks when constructing final object.
