Move to using `xl.meta` data structure to keep temporary partInfo,
this allows for a future change where we move to different parts to
different drives.
PUT shall only proceed if pre-conditions are met, the new
code uses
- x-minio-source-mtime
- x-minio-source-etag
to verify if the object indeed needs to be replicated
or not, allowing us to avoid StatObject() call.
When limiting listing do not count delete, since they may be discarded.
Extend limit, since we may be discarding the forward-to marker.
Fix directories always being sent to resolve, since they didn't return as match.
On occasion this test fails:
```

2022-09-12T17:22:44.6563751Z erasure-object_test.go:1214: Test 2: Expected data to have md5sum = `c946b71bb69c07daf25470742c967e7c`, found `7d16d23f07072af1a809707ba101ae07`

Theory: Both objects are written with the same timestamp due to lower timer resolution on Windows. This results in secondary resolution, which is deterministic, but random.
Solution: Instead of hacking in a wait we request the specific version we want. Should still keep the test relevant.
Bonus: Remote action dependency for vulncheck
If replication config could not be read from bucket metadata for some
reason, issue a panic so that unexpected replication outcomes can
be avoided for replicated buckets.
For similar reasons, adding a panic while fetching object-lock config
if it failed for reason other than non-existence of config.
minio_inter_node_traffic_errors_total currently does not track
requests body write/read errors of internode REST communications.
This commit fixes this by wrapping resp.Body.
to avoid relying on scanner-calculated replication metrics.
This will improve the accuracy of the replication stats reported.
This PR also adds on to #15556 by handing replication
traffic that could not be queued by available workers to the
MRF queue so that entries in `PENDING` status are healed faster.
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.
When healing is parallelized by setting the ` _MINIO_HEAL_WORKERS`
environment variable, multiple goroutines may race while updating the disk's
healing tracker. This change serializes only these concurrent updates using a
channel. Note, the healing tracker is still not concurrency safe in other contexts.
This PR is a continuation of the previous change instead
of returning an error, instead trigger a spot heal on the
'xl.meta' and return only after the healing is complete.
This allows for future GETs on the same resource to be
consistent for any version of the object.
