FS/Multipart: Fix race between PutObjectPart and Complete/Abort multipart. close(timeoutCh) on complete/abort so that a racing PutObjectPart does not leave a dangling go-routine.
Fixes#3351
This change brings in changes at multiple places
- Reuse buffers at almost all locations ranging
from rpc, fs, xl, checksum etc.
- Change caching behavior to disable itself
under low memory conditions i.e < 8GB of RAM.
- Only objects cached are of size 1/10th the size
of the cache for example if 4GB is the cache size
the maximum object size which will be cached
is going to be 400MB. This change is an
optimization to cache more objects rather
than few larger objects.
- If object cache is enabled default GC
percent has been reduced to 20% in lieu
with newly found behavior of GC. If the cache
utilization reaches 75% of the maximum value
GC percent is reduced to 10% to make GC
more aggressive.
- Do not use *bytes.Buffer* due to its growth
requirements. For every allocation *bytes.Buffer*
allocates an additional buffer for its internal
purposes. This is undesirable for us, so
implemented a new cappedWriter which is capped to a
desired size, beyond this all writes rejected.
Possible fix for #3403.
- This is to ensure that the any new config references made to the
serverConfig is also backed by a mutex lock.
- Otherwise any new config assigment will also replace the member mutex
which is currently used for safe access.
EOF err message in Peek Protocol is shown when a client closes the
connection in the middle of peek protocol, this commit hides it since it
doesn't make sense to show it
Current code always appends to a file only if 1byte or
more was sent on the wire was affecting both PutObject
and PutObjectPart uploads.
This patch fixes such a situation and resolves#3385
backgroundAppend type's abort method should wait for appendParts to finish
writing ongoing appending of parts in the background before cleaning up
the part files.
Previously minio server expects content-length-range values as integer
in JSON. However Amazon S3 handles content-length-range values as
integer and strings.
This patch adds support for string values.
Since we moved out reconnection logic from net-rpc-client.go
we should do it from the top-layer properly and bring back
the code to reconnect properly in-case the connection is lost.
setGlobalsFromContext() is added to set global variables after parsing
command line arguments. Thus, global flags will be honored wherever
they are placed in minio command.
Make sure all S3 signature requests are not re-directed
to `/minio`. This should be only done for JWT and some
Anonymous requests.
This also fixes a bug found from https://github.com/bji/libs3
```
$ s3 -u list
ERROR: XmlParseFailure
```
Now after this fix shows proper output
```
$ s3 -u list
Bucket Created

It would make sense to enable logger just after config initialisation.
That way, errorIf() and fatalIf() will be usable and can catch error
like invalid access and key errors.
This patch brings in changes from miniobrowser repo.
