Dont print the error errFileNotFound, as it is expected that concurrent
complete-multipart-uploads or abort-multipart-uploads would have deleted
the file, and the file may not be found
Fixes: https://github.com/minio/minio/issues/5056
Every so often we get requirements for creating
directories/prefixes and we end up rejecting
such requirements. This PR implements this and
allows empty directories without any new file
addition to backend.
Existing lower APIs themselves are leveraged to provide
this behavior. Only FS backend supports this for
the time being as desired.
s3cmd cli fails when trying to upload a file to azure gateway.
Previous fixes in azure to handle client side encryption alone
did not completely address the problem.
We need to possibilly convert all the x-amz-meta-<name>
, i.e specifically <name> should be converted into a
C# identifier as mentioned in the docs for `put-blob`.

There is a separate issue with s3cmd after this fix is applied where
the ETag is wronly validated https://github.com/s3tools/s3cmd/issues/880
But that is an upstream s3cmd problem which wrongly interprets ETag
to be md5sum of the content that was uploaded.
This PR addresses a long standing dependency on
`gopkg.in/check.v1` project used for our tests.
All tests are re-written to use the go default
testing framework instead.
There was no reason for us to use an external
package where Go tools are sufficient for this.
This is done to avoid repeated declaration of not-implemented
functions for each gateway. It also avoids a possible bug in go
https://github.com/golang/go/issues/18468 which is triggered on
our multiple PRs already.
- Add release-time conversion helpers
- Split GetCurrentReleaseTime() into two simpler functions.
- Avoid appending strings when assembling user-agent string.
- Reorder release info URLs to check the newer URLs earlier.
- Remove trivial low-level functions created solely for the purpose of
writing tests.
- Remove some unnecessary tests.
Amazon S3 API expects all incoming stream has a content-length
set it was superflous for us to support object layer which supports
unknown sized stream as well, this PR removes such requirements
and explicitly error out if input stream is less than zero.
* Enable ListMultipartUploads and ListObjectParts for FS.
Previously we had disabled ListMultipartUploads and ListObjectParts
to see if any clients break. Docker registry broke. This patch
enables ListMultipartUploads and ListObjectParts, however
ListMultipartUploads with prefix based listing is not
supported (which is not used by docker registry anyway).
i.e ListMultipartUploads will need exact object name.
Gateway implementation of ListObjectsV1 does not validate maxKeys range.
Raise an InvalidArgument when maxKeys is negative so that ListObjects
call is compatible with S3 on all gateways.
Gateway interface implementations of GetBucketInfo() under
azure and s3 gateway did not perform any bucketname input
validation resulting in incorrect responses when the tests
are expecting InvalidBucketName.
Fixes#4983
When running `make test` in docker, two test cases cause hanging.
This Patch fixes the problem by removing those test cases.
Thanks to @ws141 for identifying the problem.
The reedsolomon library now avoids allocations during reconstruction.
This change exploits that to reduce memory allocs and GC preasure during
healing and reading.
Previously we were wrongly adding `?` as part
of the resource name, add a test case to check
if this is handled properly.
Thanks to @kannappanr for reproducing this.
Without this change presigned URL generated with following
command would fail with signature mismatch.
```
aws s3 presign s3://testbucket/functional-tests.sh

On *NIX platforms the statfs(2) system call returns a struct containing both the
free blocks in the filesystem (Statfs_t.Bfree) and the free blocks available to
the unprivileged or non-superuser (Statfs_t.Bavail).
The `Bfree` and `Bavail` fields (with `Bfree >= Bavail`) will be set to
different values on e.g. filesystems such as ext4 that reserve a certain
percentage of the filesystem blocks which may only be allocated by admnistrative
privileged processes.
The calculations for the `Total` disk space need to subtract the difference
between the `Bfree` and `Bavail` fields for it to correctly show the total
available storage space available for unprivileged users.
This implicitly fixes a bug where the `Used = Total - Free` calculation yielded
different (and also incorrect) results for identical contents stored when only
the sizes of the disks or backing volumes differed. (as can be witnessed in the
`Used:` value displayed in the Minio browser)

It can happen that an incoming PutObject() request might
have inputs of following form eg:-
- bucketName is 'testbucket'
- objectName is '/'
bucketName exists and was previously created but there
are no other objects in this bucket. In a situation like
this parentDirIsObject() goes into an infinite loop.
Verifying that if '/' is an object fails on both backends
but the resulting `path.Dir('/')` returns `'/'` this causes
the closure to loop onto itself.
Fixes#4940
This change removes the ReadFileWithVerify function from the
StorageAPI. The ReadFile was basically a redirection to ReadFileWithVerify.
This change removes the redirection and moves the logic of
ReadFileWithVerify directly into ReadFile.
This removes a lot of unnecessary code in all StorageAPI implementations.
Fixes#4946
* review: fix doc and typos
