In a multi-pool setup when disks are coming up, or in a single pool
setup let's say with 100's of erasure sets with a slow network.
It's possible when healing is attempted on `.minio.sys/config`
folder, it can lead to healing unexpectedly deleting some policy
files as dangling due to a mistake in understanding when `isObjectDangling`
is considered to be 'true'.
This issue happened in commit 30135eed86
when we assumed the validMeta with empty ErasureInfo is considered
to be fully dangling. This implementation issue gets exposed when
the server is starting up.
This is most easily seen with multiple-pool setups because of the
disconnected fashion pools that come up. The decision to purge the
object as dangling is taken incorrectly prior to the correct state
being achieved on each pool, when the corresponding drive let's say
returns 'errDiskNotFound', a 'delete' is triggered. At this point,
the 'drive' comes online because this is part of the startup sequence
as drives can come online lazily.
This kind of situation exists because we allow (totalDisks/2) number
of drives to be online when the server is being restarted.
Implementation made an incorrect assumption here leading to policies
getting deleted.
Added tests to capture the implementation requirements.
data shards were wrong due to a healing bug
reported in #13803 mainly with unaligned object
sizes.
This PR is an attempt to automatically avoid
these shards, with available information about
the `xl.meta` and actually disk mtime.
- deleting policies was deleting all LDAP
user mapping, this was a regression introduced
in #13567
- deleting of policies is properly sent across
all sites.
- remove unexpected errors instead embed the real
errors as part of the 500 error response.
an active running speedTest will reject all
new S3 requests to the server, until speedTest
is complete.
this is to ensure that speedTest results are
accurate and trusted.

dataDir loosely based on maxima is incorrect and does not
work in all situations such as disks in the following order
- xl.json migration to xl.meta there may be partial xl.json's
leftover if some disks are not yet connected when the disk
is yet to come up, since xl.json mtime and xl.meta is
same the dataDir maxima doesn't work properly leading to
quorum issues.
- its also possible that XLV1 might be true among the disks
available, make sure to keep FileInfo based on common quorum
and skip unexpected disks with the older data format.
Also, this PR tests upgrade from older to a newer release if the
data is readable and matches the checksum.
NOTE: this is just initial work we can build on top of this to do further tests.
- The race happens with a goroutine that refreshes IAM cache data from storage.
- It could lead to deleted users re-appearing as valid live credentials.
- This change also causes CI to run tests without a race flag (in addition to
running it with).
A recent regression caused new disks not being re-formatted. In the old
code, a disk needed be 'online' to be chosen to be formatted but the
disk has to be already formatted for XL storage IsOnline() function to
return true.
It is enough to check if XL storage is nil or not if we want to avoid
formatting root disks.

This feature also changes the default port where
the browser is running, now the port has moved
to 9001 and it can be configured with
```
--console-address ":9001"
```
as there is no automatic way to detect if there
is a root disk mounted on / or /var for the container
environments due to how the root disk information
is masked inside overlay root inside container.
this PR brings an environment variable to set
root disk size threshold manually to detect the
root disks in such situations.

current master breaks this important requirement
we need to preserve legacyXLv1 format, this is simply
ignored and overwritten causing a myriad of issues
by leaving stale files on the namespace etc.
for now lets still use the two-phase approach of
writing to `tmp` and then renaming the content to
the actual namespace.
Tests environments (go test or manual testing) should always consider
the passed disks are root disks and should not rely on disk.IsRootDisk()
function. The reason is that this latter can return a false negative
when called in a busy system. However, returning a false negative will
only occur in a testing environment and not in a production, so we can
accept this trade-off for now.
PutObject on multiple-zone with versioning would not
overwrite the correct location of the object if the
object has delete marker, leading to duplicate objects
on two zones.
This PR fixes by adding affinity towards delete marker
when GetObjectInfo() returns error, use the zone index
which has the delete marker.
- adding oauth support to MinIO browser (#8400) by @kanagaraj
- supports multi-line get/set/del for all config fields
- add support for comments, allow toggle
- add extensive validation of config before saving
- support MinIO browser to support proper claims, using STS tokens
- env support for all config parameters, legacy envs are also
supported with all documentation now pointing to latest ENVs
- preserve accessKey/secretKey from FS mode setups
- add history support implements three APIs
- ClearHistory
- RestoreHistory
- ListHistory
- add help command support for each config parameters
- all the bug fixes after migration to KV, and other bug
fixes encountered during testing.
Mint is the functional testing platform for Minio server. So, it is
important that each PR to Minio server repository is checked for
addition/updating of Mint test cases.
