Incoming request params in presigned can come in different order
for different implementations. Rather than verifying a full string
we should verify individual params instead.
This patch fixes an incompatibility issue with AWS SDK Java.
Fixes#1059 - Thanks to @notnoopci for reporting this problem.
listObjects was returning inconsistent results, i.e missing
entries during recursive and non-recursive listing. This led
to 'mc mirror' copying contents repeatedly consisdering
these files to be missing on the destination.
This patch addresses this problem - fixes#1056
HMAC is a much simpler implementation, providing the same
benefits as RSA, avoids additional steps and keeps the code
simpler.
This patch also additionally
- Implements PutObjectURL API.
- GetObjectURL, PutObjectURL take TargetHost as another
argument for generating URL's for proper target destination.
- Adds experimental TLS support for JSON RPC calls.
Without this change listObjects() goes into an infinite loop for
files which have special characters i.e "++" encoded with "%2B%2B".
We have to unescape and convert them to their native representation
before being used internally.
Fixes#1052
Existing code
```
{
if os.IsNotExist(e) {
e = os.MkdirAll(objectDir, 0700)
if e != nil {
return "", probe.NewError(e)
}
}
return "", probe.NewError(e) ---> Error was here.
}
```
For a successful 'MkdirAll' it would still return an empty uploadID,
but the 'error' would be nil. This would succeed the request but
client would fail.
Fix is to re-arrange the logic. Thanks to Alexander Neumann @fd0, for
reporting this problem.
- limit list buckets to limit only 100 buckets, all uppercase buckets
are now lowercase and work transparently with all calls.
- Change disk.Stat to disk.GetInfo and return back disk.Info{} struct.
- Introduce new ioutils package which implements ReadDirN(path, n),
ReadDirNamesN(path, n)
To change default region from 'us-east-1' to 'custom'.
Add a region value in your 'config.json'.
"version": "2",
"credentials": {
"accessKeyId": "****************",
"secretAccessKey": "***************",
"region": "my-region"
},
Golang http server strips off 'Expect' header, if the
client sent this as part of signed headers we need to
handle otherwise we would see a signature mismatch.
`aws-cli` sets this as part of signed headers which is
a bad idea since servers trying to implement AWS
Signature version '4' will all encounter this issue.
According to
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.20
Expect header is always of form:
Expect = "Expect" ":" 1#expectation
expectation = "100-continue" | expectation-extension
So it safe to assume that '100-continue' is what would
be sent, for the time being keep this work around.
