500k is a reasonable limit for any single MinIO
cluster deployment, in future we may increase this
value.
However for now we are going to keep this limit.
also use designated names for internal
calls
- storageREST calls are storageR
- lockREST calls are lockR
- peerREST calls are just peer
Named in this fashion to facilitate wildcard matches
by having prefixes of the same name.
Additionally, also enable funcNames for generic handlers
that return errors, currently we disable '<unknown>'
PR #15052 caused a regression, add the missing metrics back.
Bonus:
- internode information should be only for distributed setups
- update the dashboard to include 4xx and 5xx error panels.
Currently minio_s3_requests_errors_total covers 4xx and
5xx S3 responses which can be confusing when s3 applications
sent a lot of HEAD requests with obvious 404 responses or
when the replication is enabled.
Add
- minio_s3_requests_4xx_errors_total
- minio_s3_requests_5xx_errors_total
to help users monitor 4xx and 5xx HTTP status codes separately.
MinIO configuration is loaded after the initialization of the server
handlers, which will miss the initialization of the bucket forwarder
handler.
Though the federation is deprecated, let's fix this for the time being.
- combine similar looking functionalities into single
handlers, and remove unnecessary proxying of the
requests at handler layer.
- remove bucket forwarding handler as part of default setup
add it only if bucket federation is enabled.

read/writers are not concurrent in handlers
and self contained - no need to use atomics on
them.
avoids unnecessary contentions where it's not
required.
MinIO might be running inside proxies, and
console while being on another port might not be
reachable on a specific port behind such proxies.
For such scenarios customize the redirect URL
such that console can be redirected to correct
proxy endpoint instead.
fixes#12661
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"
```
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
IAM not initialized doesn't mean we can't still
read the content from the disk, we should just
allow the request to go-through if object layer
is initialized.
https://github.com/minio/console takes over the functionality for the
future object browser development

DNSCache dialer is a global value initialized in
init(), whereas `go` keeps `var =` before `init()`
, also we don't need to keep proxy routers as
global entities - register the forwarder as
necessary to avoid crashes.
additionally also configure http2 healthcheck
values to quickly detect unstable connections
and let them timeout.
also use single transport for proxying requests
The bucket forwarder handler considers MakeBucket to be always local but
it mistakenly thinks that PUT bucket lifecycle to be a MakeBucket call.
Fix the check of the MakeBucket call by ensuring that the query is empty
in the PUT url.
This PR adds transition support for ILM
to transition data to another MinIO target
represented by a storage class ARN. Subsequent
GET or HEAD for that object will be streamed from
the transition tier. If PostRestoreObject API is
invoked, the transitioned object can be restored for
duration specified to the source cluster.
when server is booting up there is a possibility
that users might see '503' because object layer
when not initialized, then the request is proxied
to neighboring peers first one which is online.
- Implement a new xl.json 2.0.0 format to support,
this moves the entire marshaling logic to POSIX
layer, top layer always consumes a common FileInfo
construct which simplifies the metadata reads.
- Implement list object versions
- Migrate to siphash from crchash for new deployments
for object placements.
Fixes#2111
Historically due to lack of support for middlewares
we ended up writing wrapped handlers for all
middlewares on top of the gorilla/mux, this causes
multiple issues when we want to let's say
- Overload r.Body with some custom implementation
to track the incoming Reads()
- Add other sort of top level checks to avoid
DDOSing the server with large incoming HTTP
bodies.
Since 1.7.x release gorilla/mux provides proper
use of middlewares, which are honored by the muxer
directly. This makes sure that Go can honor its
own internal ServeHTTP(w, r) implementation where
Go net/http can wrap into its own customer readers.
This PR as a side-affect fixes rare issues of client
hangs which were reported in the wild but never really
understood or fixed in our codebase.
