We need to have local peer initialized properly
for listen bucket to work, current code did initialize
properly but the resulting code was initializing
peer on a wrong target v/s what listen bucket expected
it to be.
This regression came in de204a0a52Fixes#4158
Avoid using `time.Now()` instead rely on UTC time
for the final deadline, this is to be consistent with
all our internal functions.
Reduce the default read timeout to 15 seconds
in lieu with a newly discovered issue
- https://github.com/minio/minio/issues/4139
Additionally also change the Read() conn wrapper
to set deadline only upon successful Reads().
Current log prints in this form
```
ERRO[8150] Lock maintenance failed to remove entry for write
lock (should never happen)%!!(MISSING)(EXTRA ....
```
Fix this by using proper formatting directive.
Duration for which a lock was held can be computed from the `Since`
field of `OpsLockState`. It is the difference between current time and
time at which the namespace lock was held. This change avoids
superfluous instrumentation.
Previous value was set to avoid large cache value build
up but we can clearly see this can cause lots of GC
pauses which can lead to significant drop in performance.
Change this value to 50% and decrease the value to 25%
once the 75% cache size is used. To have a larger
window for GC pauses.
Another change is to only allow caching if a server has
more than 24GB of RAM instead of 8GB.
Such that in a situation where all errors were
ignored we need to reduce the errors using
readQuorum to get a consistent error value.
Without this change errors generated will
never be consistent with for an expected scenario.
For example in a 6 disk setup 1 disk is missing
and 5 do not have the volume (testbucket)
Without this change Stat() would result in different
errors depending on which disk died. Can cause
confusion to S3 client application.
This change addresses need to track type of
errors we ignored and bring readQuorum to
choose the maximally occuring as the value
of truth.
getBucketInfo() should keep track errors ignored,
such that in a situation where all errors were
ignored we need to reduce the errors using readQuorum
to get a consistent error value.
This is the problem we see with DiskNotFound test
disks are randomly removed.

- Due to usage of amazon SDK, spark expects md5sum of empty string to be
returned when it does PUT on a directory.
- The fix returns md5sum of a empty string for the above mentioned case.
- This fixes the issue of Apache Spark not being able to write into Minio.
Ignore any network errors when registering a webhook
notifier during Minio startup sequence. This way server
can be started even if the webhook endpoint is not available
and unreachable.
go fails to build Minio under at least, armv6 and 386 due to some
inconsistencies in the type of one syscall variable in different
architectures. This PR casts that variable to uint64 to achieve
the desired consistency.
This is to comply with S3 behavior, we previously removed
reading `fs.json` for optimization reasons but we have a
reason to believe that providing ETag and using gjson
provides needed benefit of not having to deal with
unmarshalling overhead of golang stdlib.
Fixes#4028
Values of canonicalized query resources should be unescaped before calculating
the signature. This bug is not noticed before because partNumber and uploadID
values in Minio doesn't have characters that need to be escaped.
Separate out validating v/s parsing logic in
isValidLocationConstraint() into parseLocationConstraint()
and isValidLocation()
Additionally also set `X-Amz-Bucket-Region` as part of the
common headers for the clients to fallback on in-case of any
region related errors.
Healing of buckets, objects and incomplete uploads are implemented and
available via admin REST APIs. Additionally, it is available via mc admin
sub-command. The warning is no longer relevant.
Fixes#4030
