disk usage crawling is not needed when a tenant
is not sharing the same disk for multiple other
tenants. This PR adds an optimization when we
see a setup uses entire disk, we simply rely on
statvfs() to give us total usage.
This PR also additionally adds low priority
scheduling for usage check routine, such that
other go-routines blocked will be automatically
unblocked and prioritized before usage.
Minio server returns 403 (access denied) for head requests to prefixes
without trailing "/", this is different from S3 behaviour. S3 returns
404 in such cases.
Fixes#6080
This commit prevents complete server failures caused by
`logger.CriticalIf` calls. Instead of calling `os.Exit(1)`
the function now executes a panic with a special value
indicating that a critical error happend. At the top HTTP
handler layer panics are recovered and if its a critical
error the client gets an InternalServerError status code.
Further this allows unit tests to cover critical-error code
paths.
Add compile time GOROOT path to the list of prefix
of file paths to be removed.
Add webhandler function names to the slice that
stores function names to terminate logging.
During startup until the object layer is initialized
logger is disabled to provide for a cleaner UI error
message. CriticalIf is disabled, use FatalIf instead.
Also never call os.Exit(1) on running servers where
you can return error to client in handlers.
This commit limits the amount of memory allocated by the
S3 Multi-Object-Delete-API. The server used to allocate as
many bytes as provided by the client using Content-Length.
S3 specifies that the S3 Multi-Object-Delete-API can delete
at most 1000 objects using a single request.
(See: https://docs.aws.amazon.com/AmazonS3/latest/API/multiobjectdeleteapi.html)
Since the maximum S3 object name is limited to 1024 bytes the
XML body sent by the client can only contain up to 1000 * 1024
bytes (excluding XML format overhead).
This commit limits the size of the parsed XML for the S3
Multi-Object-Delete-API to 2 MB. This fixes a DoS
vulnerability since (auth.) clients, MitM-adversaries
(without TLS) and un-auth. users accessing buckets allowing
multi-delete by policy can kill the server.
This behavior is similar to the AWS-S3 implementation.
This PR adds CopyObject support for objects residing in buckets
in different Minio instances (where Minio instances are part of
a federated setup).
Also, added support for multiple Minio domain IPs. This is required
for distributed deployments, where one deployment may have multiple
nodes, each with a different public IP.
Buckets already present on a Minio server before it joins a
bucket federated deployment will now be added to etcd during
startup. In case of a bucket name collision, admin is informed
via Minio server console message.
Added configuration migration for configuration stored in etcd
backend.
Also, environment variables are updated and ListBucket path style
request is no longer forwarded.
This commit fixes the issue introduced in #6023
The clicks on folder names direct the users inside the folders; while
the clicks on file names don't download the files, and will open file
previews on a separate modal in the future. Additionally, when a file
has been selected using the checkbox, it can now be downloaded without
being inside a zip file.
Fixes#6026
This commit has been done according to @abperiasamy's feedback as we
are going to reserve the click on file icon to open the preview modal
in the future.
Also, when the user now selects a single file, the file itself is
downloaded instead of a .zip file containing the file.
Fixes#6019
Added support for new RPC support using HTTP POST. RPC's
arguments and reply are Gob encoded and sent as HTTP
request/response body.
This patch also removes Go RPC based implementation.
