do not modify opts.UserDefined after object-handler
has set all the necessary values, any mutation needed
should be done on a copy of this value not directly.
As there are other pieces of code that access opts.UserDefined
concurrently this becomes challenging.
fixes#14856
When a decommission task is successfully completed, failed, or canceled,
this commit allows restarting the decommission again. Restarting is not
allowed when there is an ongoing decommission task.
this PR introduces a few changes such as
- sessionPolicyName is not reused in an extracted manner
to apply policies for incoming authenticated calls,
instead uses a different key to designate this
information for the callers.
- this differentiation is needed to ensure that service
account updates do not accidentally store JSON representation
instead of base64 equivalent on the disk.
- relax requirements for Deleting a service account, allow
deleting a service account that might be unreadable, i.e
a situation where the user might have removed session policy
which now carries a JSON representation, making it unparsable.
- introduce some constants to reuse instead of strings.
fixes#14784
If an invalid status code is generated from an error we risk panicking. Even if there
are no potential problems at the moment we should prevent this in the future.
Add safeguards against this.

space characters at the beginning or at the end can lead to
confusion under various UI elements in differentiating the
actual name of "policy, user or group" - to avoid this behavior
this PR onwards we shall reject such inputs for newer entries.
existing saved entries will behave as is and are going to be
operable until they are removed/renamed to something more
meaningful.
- When using multiple providers, claim-based providers are not allowed. All
providers must use role policies.
- Update markdown config to allow `details` HTML element
this is allowed as long as order is preserved as is
on an existing setup, the new command line is updated
in `pool.bin` to facilitate future decommission's on
these pools.
introduce x-minio-force-create environment variable
to force create a bucket and its metadata as required,
it is useful in some situations when bucket metadata
needs recovery.
improvements in this PR include
- decommission objects that have __XLDIR__ suffix
- decommission objects that have `null` version on
a versioned bucket.
- make sure to look for any "decom" failures to ensure
that we do not wrong conclude decom as complete without
all files getting copied over.
- break out eagerly upon first error for objects with
multiple versions, leave the object as is for support
debugging and analysis.
heal bucket metadata and IAM entries for
sites participating in site replication from
the site with the most updated entry.

The site replication status call was using a loop iteration variable sent
directly into go-routines instead of being passed as an argument. As the
variable is being updated in the loop, previously launched go routines do not
necessarily use the value at the time they were launched.
This PR fixes two issues
- The first fix is a regression from #14555, the fix itself in #14555
is correct but the interpretation of that information by the
object layer code for "replication" was not correct. This PR
tries to fix this situation by making sure the "Delete" replication
works as expected when "VersionPurgeStatus" is already set.
Without this fix, there is a DELETE marker created incorrectly on
the source where the "DELETE" was triggered.
- The second fix is perhaps an older problem started since we inlined-data
on the disk for small objects, CopyObject() incorrectly inline's
a non-inlined data. This is due to the fact that we have code where
we read the `part.1` under certain conditions where the size of the
`part.1` is less than the specific "threshold".
This eventually causes problems when we are "deleting" the data that
is only inlined, which means dataDir is ignored leaving such
dataDir on the disk, that looks like an inconsistent content on
the namespace.
fixes#14767
It is wasteful to allow parallel upgrades of MinIO server. This also generates
weird error invoked by selfupdate module when it happens such as:
'rename /opt/bin/.minio.old /opt/bin/..minio.old.old'
currently filterPefix was never used and set
that would filter out entries when needed
when `prefix` doesn't end with `/` - this
often leads to objects getting Walked(), Healed()
that were never requested by the caller.
without this wait there is a potential for some objects
that are in actively being decommissioned would cancel,
however the decommission status might wrongly conclude
this as "Complete".
To avoid this make sure to add waitgroups on the parallel
workers, allowing parallel copies to complete fully before
we return.
