An issue was reproduced when there a no more inodes
available on an existing setup of 4 disks, now we
took one of the disks and reformatted it to relinquish
inodes. Now we attempt to bring the fresh disk back
into setup and perform a heal - at this point creating
new `format.json` fails on existing disks since they
do not have more inodes available.
At this point due to quorum failure, we end up deleting
existing `format.json` as well, this PR removes the code
which deletes existing `format.json` as there is no need
to delete them.
Previous PR 2afd196c83 fixed
the issue of quorum based listing for regular objects, this
PR continues on this idea by extending this support to
object directory prefixes as well.

Set GOPATH string to empty in build-constants.go
Check for both compile time GOPATH and default GOPATH
while trimming the file path in the stack trace.

This PR fixes two different variant of deadlocks in
notification.
- holding write lock on the bucket competing with read lock
- holding competing locks on read/save notification config
This PR adds disk based edge caching support for minio server.
Cache settings can be configured in config.json to take list of disk drives,
cache expiry in days and file patterns to exclude from cache or via environment
variables MINIO_CACHE_DRIVES, MINIO_CACHE_EXCLUDE and MINIO_CACHE_EXPIRY
Design assumes that Atime support is enabled and the list of cache drives is
fixed.
- Objects are cached on both GET and PUT/POST operations.
- Expiry is used as hint to evict older entries from cache, or if 80% of cache
capacity is filled.
- When object storage backend is down, GET, LIST and HEAD operations fetch
object seamlessly from cache.
Current Limitations
- Bucket policies are not cached, so anonymous operations are not supported in
offline mode.
- Objects are distributed using deterministic hashing among list of cache
drives specified.If one or more drives go offline, or cache drive
configuration is altered - performance could degrade to linear lookup.
Fixes#4026
This is a trival fix to support server level WORM. The feature comes
with an environment variable `MINIO_WORM`.
Usage:
```
$ export MINIO_WORM=on
$ minio server endpoint
```
Object deletion should not be possible if quorum is not
available. This PR updates deleteObject() to check for
quorum errors before proceeding with object deletion.
Fixes#5535
This commit adds the bucket delete and bucket policy functionalities
to the browser.
Part of rewriting the browser code to follow best practices and
guidelines of React (issues #5409 and #5410)
The backend code has been modified by @krishnasrinivas to prevent
issue #4498 from occuring. The relevant changes have been made to the
code according to the latest commit and the unit tests in the backend.
This commit also addresses issue #5449.
Migration regression got introduced in 9083bc152e
adding more unit tests to catch this scenario, we need to fix this by
re-writing the formats after the migration to 'V3'.
This bug only happens when a user is migrating directly from V1 to V3,
not from V1 to V2 and V2 to V3.
Added additional unit tests to cover these situations as well.
Fixes#5667
- Add head method for healthcheck endpoint. Some platforms/users
may use the HTTP Head method to check for health status.
- Add liveness and readiness probe examples in Kubernetes yaml
example docs. Note that readiness probe not added to StatefulSet
example due to https://github.com/kubernetes/kubernetes/issues/27114

This PR adds readiness and liveness endpoints to probe Minio server
instance health. Endpoints can only be accessed without authentication
and the paths are /minio/health/live and /minio/health/ready for
liveness and readiness respectively.
The new healthcheck liveness endpoint is used for Docker healthcheck
now.

In kubernetes statefulset like environments when secrets
are mounted to pods they have sub-directories, we should
ideally be only looking for regular files here and skip
all others.
Fix a compatibility issue with AWS S3 where to do key rotation
we need to replace an existing object's metadata. In such a
scenario "REPLACE" metadata directive is not necessary.
- Data from disk was being read after bitrot verification to return
data for GetObject. Strictly speaking this does not guarantee bitrot
protection, as disks may return bad data even temporarily.
- This fix reads data from disk, verifies data for bitrot and then
returns data to the client directly.
Current code didn't implement the logic to support
decrypting encrypted multiple parts, this PR fixes
by supporting copying encrypted multipart objects.
Currently we reply back `X-Minio-Internal` values
back to the client for an encrypted object, we should
filter these out and only reply AWS compatible headers.
