ConsoleUI like applications rely on combination of
ListServiceAccounts() and InfoServiceAccount() to populate
UI elements, however individually these calls can be slow
causing the entire UI to load sluggishly.
i.e., this rule element doesn't apply to DEL markers.
This is a breaking change to how ExpiredObejctDeleteAllVersions
functions today. This is necessary to avoid the following highly probable
footgun scenario in the future.
Scenario:
The user uses tags-based filtering to select an object's time to live(TTL).
The application sometimes deletes objects, too, making its latest
version a DEL marker. The previous implementation skipped tag-based filters
if the newest version was DEL marker, voiding the tag-based TTL. The user is
surprised to find objects that have expired sooner than expected.
* Add DelMarkerExpiration action
This ILM action removes all versions of an object if its
the latest version is a DEL marker.
```xml
<DelMarkerObjectExpiration>
<Days> 10 </Days>
</DelMarkerObjectExpiration>
```
1. Applies only to objects whose,
• The latest version is a DEL marker.
• satisfies the number of days criteria
2. Deletes all versions of this object
3. Associated rule can't have tag-based filtering
Includes,
- New bucket event type for deletion due to DelMarkerExpiration
calling a remote target remove with a perfectly
well constructed ARN can lead to a crash for a bucket
with no replication configured.
This PR fixes, and adds a crash check for ImportMetadata
as well.

This would reduce the size of data in response of metrics
listing. While graphing we can default these metrics with
a zero value if not found.

Unfreeze as soon as the incoming connection is terminated and don't wait for everything to complete.
We don't want to keep the services frozen if something becomes stuck.
- handle errFileCorrupt properly
- micro-optimization of sending done() response quicker
to close the goroutine.
- fix logger.Event() usage in a couple of places
- handle the rest of the client to return a different error other than
lastErr() when the client is closed.
listPathRaw() counts errDiskNotFound as a valid error to indicate a
listing stream end. However, storage.WalkDir() is allowed to return
errDiskNotFound anytime since grid.ErrDisconnected is converted to
errDiskNotFound.
This affects fresh disk healing and should affect S3 listing as well.

Since the standard process collector implements only a subset of these

captures all the process metrics we need.
Since the object is being permanently deleted, the lack of read quorum should not
matter as long as sufficient disks are online to complete the deletion with parity
requirements.
If several pools have the same object with insufficient read quorum, attempt to
delete object from all the pools where it exists
At server startup, LDAP configuration is validated against the LDAP
server. If the LDAP server is down at that point, we need to cleanly
disable LDAP configuration. Previously, LDAP would remain configured but
error out in strange ways because initialization did not complete
without errors.
When importing access keys (i.e. service accounts) for LDAP accounts,
we are requiring groups to exist under one of the configured group base
DNs. This is not correct. This change fixes this by only checking for
existence and storing the normalized form of the group DN - we do not
return an error if the group is not under a base DN.
Test is updated to illustrate an import failure that would happen
without this change.
Existing IAM import logic for LDAP creates new mappings when the
normalized form of the mapping key differs from the existing mapping key
in storage. This change effectively replaces the existing mapping key by
first deleting it and then recreating with the normalized form of the
mapping key.
For e.g. if an older deployment had a policy mapped to a user DN -
`UID=alice1,OU=people,OU=hwengg,DC=min,DC=io`
instead of adding a mapping for the normalized form -
`uid=alice1,ou=people,ou=hwengg,dc=min,dc=io`
we should replace the existing mapping.
This ensures that duplicates mappings won't remain after the import.
Some additional cleanup cases are also covered. If there are multiple
mappings for the name normalized key such as:
`UID=alice1,OU=people,OU=hwengg,DC=min,DC=io`
`uid=alice1,ou=people,ou=hwengg,DC=min,DC=io`
`uid=alice1,ou=people,ou=hwengg,dc=min,dc=io`
we check if the list of policies mapped to all these keys are exactly
the same, and if so remove all of them and create a single mapping with
the normalized key. However, if the policies mapped to such keys differ,
the import operation returns an error as the server cannot automatically
pick the "right" list of policies to map.
When inspecting files like `.minio.sys/pool.bin` that may be present on multiple sets, use signature to separate them.
Also fixes null versions to actually be useful with `-export -combine`.
`minio_cluster_webhook_queue_length` was wrongly defined as `counter`
where-as it should be `gauge`
Following were wrongly defined as `gauge` when they should actually be
`counter`:
- minio_bucket_replication_sent_bytes
- minio_bucket_replication_received_bytes
- minio_bucket_replication_total_failed_bytes
- minio_bucket_replication_total_failed_count
When LDAP is enabled, previously we were:
- rejecting creation of users and groups via the IAM import functionality
- throwing a `not a valid DN` error when non-LDAP group mappings are present
This change allows for these cases as we need to support situations
where the MinIO server contains users, groups and policy mappings
created before LDAP was enabled.
instead upon any error in renameData(), we still
preserve the existing dataDir in some form for
recoverability in strange situations such as out
of disk space type errors.
Bonus: avoid running list and heal() instead allow
versions disparity to return the actual versions,
uuid to heal. Currently limit this to 100 versions
and lesser disparate objects.
an undo now reverts back the xl.meta from xl.meta.bkp
during overwrites on such flaky setups.
Bonus: Save N depth syscalls via skipping the parents
upon overwrites and versioned updates.
Flaky setup examples are stretch clusters with regular
packet drops etc, we need to add some defensive code
around to avoid dangling objects.
RenameData could start operating on inline data after timing out
and the call returned due to WithDeadline.
This could cause a buffer to write to the inline data being written.
Since no writes are in `RenameData` and the call is canceled,
this doesn't present a corruption issue. But a race is a race and
should be fixed.
Copy inline data to a fresh buffer.
This PR makes a feasible approach to handle all the scenarios
that we must face to avoid returning "panic."
Instead, we must return "errServerNotInitialized" when a
bucketMetadataSys.Get() is called, allowing the caller to
retry their operation and wait.
Bonus fix the way data-usage-cache stores the object.
Instead of storing usage-cache.bin with the bucket as
`.minio.sys/buckets`, the `buckets` must be relative
to the bucket `.minio.sys` as part of the object name.
Otherwise, there is no way to decommission entries at
`.minio.sys/buckets` and their final erasure set positions.
A bucket must never have a `/` in it. Adds code to read()
from existing data-usage.bin upon upgrade.
This PR fixes a few things
- FIPS support for missing for remote transports, causing
MinIO could end up using non-FIPS Ciphers in FIPS mode
- Avoids too many transports, they all do the same thing
to make connection pooling work properly re-use them.
- globalTCPOptions must be set before setting transport
to make sure the client conn deadlines are honored properly.
- GCS warm tier must re-use our transport
- Re-enable trailing headers support.
This reverts commit 928c0181bf.
This change was not correct, reverting.
We track 3 states with the ProxyRequest header - if replication process wants
to know if object is already replicated with a HEAD, it shouldn't proxy back
- Poorna
AWS S3 trailing header support was recently enabled on the warm tier
client connection to MinIO type remote tiers. With this enabled, we are
seeing the following error message at http transport layer.
> Unsolicited response received on idle HTTP channel starting with "HTTP/1.1 400 Bad Request\r\nContent-Type: text/plain; charset=utf-8\r\nConnection: close\r\n\r\n400 Bad Request"; err=<nil>
This is an interim fix until we identify the root cause for this behaviour in the
minio-go client package.
Keep the EC in header, so it can be retrieved easily for dynamic quorum calculations.
To not force a full metadata decode on every read the value will be 0/0 for data written in previous versions.
