Minor optimization.
- Add 1000 entries buffered channel for walkerCh.
- Reset marker after the lexical order has reached and
compare only if the marker is set.
- Fixes initiating parallel uploads, and configs being quickly
re-written by another incoming request.
- Parallel uploads work smoothly now and return expected behavior.
Fail createObject() if a file already exists and one attempts
to create a prefix/directory by same name.
Send an approriate error back to the client as 409 Conflict.
Currently the server would set 'application/octet-stream' for all
objects, set this value based on the file extension transparently.
This is useful in case of minio browser to facilitate displaying
proper icons for the different mime data types.
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)
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.
Remove option of providing Technique and handling errors based on that
choose a matrix type automatically based on number of data blocks.
INTEL recommends on using cauchy for consistent invertible matrices,
while vandermonde is faster we should default to cauchy for large
data blocks.
Stream reading needs to check for length parameter being non zero,
after Reading() a predefined set of buffer length an EOF might be returned
with length == 0.
Erasure taking this zeroed data in might wrongly encode it as part of existing
data blocks which leads to errors while decoding even when the other contents
are intact.
- Upon first time invocation ``minio controller`` would create access keys and secret id
- Upon request passing 'keys' arg ``minio controller`` would provide the keys
- Add colorized notification
This change brings a new SignatureHandler where Presigned.
Requests without Payload are handled very early before even
going through the call.
This change simplifies Donut codebase to not have signature related
logic for all API's.
Simplification is still needed for Payload based signature eg. PUT/POST calls
, which are still part of the donut codebase, which will be done subsequently
after donut re-write.
