Make sure to pass a nil pointer as a Transport to minio-go when the API config
is not initialized, this will make sure that we do not pass an interface
with a known type but a nil value.
This will also fix the update of the API remote_transport_deadline
configuration without requiring the cluster restart.

Currently, the progress of the batch job is saved in inside the job
request object, which is normally not supported by MinIO. Though there
is no apparent bug, it is better to fix this now.
Batch progress is saved in .minio.sys/batch-jobs/reports/

This allows batch replication to basically do not
attempt to copy objects that do not have read quorum.
This PR also allows walk() to provide custom
values for quorum under batch replication, and
key rotation.
it is possible that ILM or Deletes got triggered on batch
of objects that we are attempting to batch replicate, ignore
this scenario as valid behavior.
This PR changes the StatObject() to be must have for non-minio source
to being a conditional API call.
- Calls StatObject() when needed
- Calls GetObjectTagging() when needed
These calls if we do without these conditionals can cause a lot of
delays, so we avoid them if not needed in more common scenario.
batch status can perpetually wait after completion
due to a race between the MetricsHandler() returning
the active metrics in intervals of 1sec and delete
of metrics after job completion.
this PR ensures that we keep the 'status' around
for a while, i.e upto 24hrs for all the batch jobs.
// UnmarshalStrict is like Unmarshal except that any fields that are found
// in the data that do not have corresponding struct members, or mapping
// keys that are duplicates, will result in
// an error.
batch replication pull must preserve versionID regardless
of destination bucket versioning configuration.
This is similar to the issue with decommissioning and rebalancing
A new middleware function is added for admin handlers, including options
for modifying certain behaviors. This admin middleware:
- sets the handler context via reflection in the request and sends AuditLog
- checks for object API availability (skipping it if a flag is passed)
- enables gzip compression (skipping it if a flag is passed)
- enables header tracing (adding body tracing if a flag is passed)
While the new function is a middleware, due to the flags used for
conditional behavior modification, which is used in each route registration
call.
To try to ensure that no regressions are introduced, the following
changes were done mechanically mostly with `sed` and regexp:
- Remove defer logger.AuditLog in admin handlers
- Replace newContext() calls with r.Context()
- Update admin routes registration calls
Bonus: remove unused NetSpeedtestHandler
Since the new adminMiddleware function checks for object layer presence
by default, we need to pass the `noObjLayerFlag` explicitly to admin
handlers that should work even when it is not available. The following
admin handlers do not require it:
- ServerInfoHandler
- StartProfilingHandler
- DownloadProfilingHandler
- ProfileHandler
- SiteReplicationDevNull
- SiteReplicationNetPerf
- TraceHandler
For these handlers adminMiddleware does not check for the object layer
presence (disabled by passing the `noObjLayerFlag`), and for all other
handlers, the pre-check ensures that the handler is not called when the
object layer is not available - the client would get a
ErrServerNotInitialized and can retry later.
This `noObjLayerFlag` is added based on existing behavior for these
handlers only.
* Reduce allocations
* Add stringsHasPrefixFold which can compare string prefixes, while ignoring case and not allocating.
* Reuse all msgp.Readers
* Reuse metadata buffers when not reading data.
* Make type safe. Make buffer 4K instead of 8.
