The test expects from DeleteFile to return errDiskNotFound when the disk
is not available. It calls os.RemoveAll() to remove one disk after XL storage
initialization. However, this latter contains some goroutines which can
race with os.RemoveAll() and then the test fails sporadically with
returning random errors.
The commit will tweak the initialization routine of the XL storage to
only run deletion of temporary and metacache data in the background,
so TestXLStorageDeleteFile won't fail anymore.
currently, we allowed buckets to be listed from the
API call if and when the user has ListObject()
permission at the global level, this is okay to be
extended to GetBucketLocation() as well since
GetBucketLocation() is a "read" call and allowing "reads"
on a bucket has an implicit assumption that ListBuckets()
should be allowed.
This makes discoverability of access for read-only users
becomes easier or users with specific restrictions on their
policies.
This PR simplifies few things by splitting
the locks between audit, logger targets to
avoid potential contention between them.
any failures inside audit/logger HTTP
targets must only log to console instead
of other targets to avoid cyclical dependency.
avoids unneeded atomic variables instead
uses RWLock to differentiate a more common
read phase v/s lock phase.
- This change renames the OPA integration as Access Management Plugin - there is
nothing specific to OPA in the integration, it is just a webhook.
- OPA configuration is automatically migrated to Access Management Plugin and
OPA specific configuration is marked as deprecated.
- OPA doc is updated and moved.
In case of multi-pools setup, GetObjectNInfo returns a GetObjectReader
but it unlocks the read lock when quitting GetObjectNInfo. This should
not happen, unlock should only happen when GetObjectReader is closed.
- do not need to restrict prefix exclusions that do not
have `/` as suffix, relax this requirement as spark may
have staging folders with other autogenerated characters
, so we are better off doing full prefix March and skip.
- multiple delete objects was incorrectly creating a
null delete marker on a versioned bucket instead of
creating a proper versioned delete marker.
- do not suspend paths on the excluded prefixes during
delete operations to avoid creating `null` delete markers,
honor suspension of versioning only at bucket level for
delete markers.
PR #14828 introduced prefix-level exclusion of versioning
and replication - however our site replication implementation
since it defaults versioning on all buckets did not allow
changing versioning configuration once the bucket was created.
This PR changes this and ensures that such changes are honored
and also propagated/healed across sites appropriately.
Spark/Hadoop workloads which use Hadoop MR
Committer v1/v2 algorithm upload objects to a
temporary prefix in a bucket. These objects are
'renamed' to a different prefix on Job commit.
Object storage admins are forced to configure
separate ILM policies to expire these objects
and their versions to reclaim space.
Our solution:
This can be avoided by simply marking objects
under these prefixes to be excluded from versioning,
as shown below. Consequently, these objects are
excluded from replication, and don't require ILM
policies to prune unnecessary versions.
- MinIO Extension to Bucket Version Configuration
```xml
<VersioningConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Status>Enabled</Status>
<ExcludeFolders>true</ExcludeFolders>
<ExcludedPrefixes>
<Prefix>app1-jobs/*/_temporary/</Prefix>
</ExcludedPrefixes>
<ExcludedPrefixes>
<Prefix>app2-jobs/*/__magic/</Prefix>
</ExcludedPrefixes>
<!-- .. up to 10 prefixes in all -->
</VersioningConfiguration>
```
Note: `ExcludeFolders` excludes all folders in a bucket
from versioning. This is required to prevent the parent
folders from accumulating delete markers, especially
those which are shared across spark workloads
spanning projects/teams.
- To enable version exclusion on a list of prefixes
```
mc version enable --excluded-prefixes "app1-jobs/*/_temporary/,app2-jobs/*/_magic," --exclude-prefix-marker myminio/test
```
when the site is being removed is missing replication config. This can
happen when a new deployment is brought in place of a site that
is lost/destroyed and needs to delink old deployment from site
replication.
console logging peer API was broken as it would
timeout after 15minutes, this never really worked
beyond this value and basically failed to provide
the streaming "log" functionality that was expected
from this implementation.
also fix convoluted channel handling by keeping things
simple, this is rewritten.
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.

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.

this PR onwards we shall reject such inputs for newer entries.

- 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.
