- Fix tests for new changes.
- Change Golang err as 'e' for the time being, before we bring in
probe removal change.
- Remove old structs and temporary files.
This patch modifies multipart upload related functions as below
* New multipart upload call creates file
EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.uploadid
* Put object part call creates file
EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.PART_NUMBER.MD5SUM_STRING
* Abort multipart call removes all files matching
EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.*
* Complete multipart call does
1. creates a staging file
EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.complete.TEMP_NAME
then renames to
EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.complete
2. rename staging file
EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.complete
to EXPORT_DIR/BUCKET/PATH/TO/OBJECT
Signature calculation has now moved out from being a package to
top-level as a layered mechanism.
In case of payload calculation with body, go-routines are initiated
to simultaneously write and calculate shasum. Errors are sent
over the writer so that the lower layer removes the temporary files
properly.
This commit prefers the use of 'defer' for fs.Unlock (and fs.RUnlock)
because it is more idiomatic Go and reduces repetition in the code,
lending to a cleaner code base.
It also switches a few uses of the lock to read-only locks, which should
improve performance of those functions dramatically in certain contexts.
This API takes input XML input in following form.
```
<?xml version="1.0" encoding="UTF-8"?>
<Delete>
<Quiet>true</Quiet>
<Object>
<Key>Key</Key>
</Object>
<Object>
<Key>Key</Key>
</Object>
...
</Delete>
```
and responds the list of successful deletes, list of errors
for all the deleted objects.
```
<?xml version="1.0" encoding="UTF-8"?>
<DeleteResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Deleted>
<Key>sample1.txt</Key>
</Deleted>
<Error>
<Key>sample2.txt</Key>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
</Error>
</DeleteResult>
```
- Move fs-definitions.go and break them into fs-datatypes.go, fs-bucket-acl.go
and fs-utils.go
- Move api-definitions.go to api-response.go, where they should be.
- Move web-definitions to its related handlers.
- Fixes initiating parallel uploads, and configs being quickly
re-written by another incoming request.
- Parallel uploads work smoothly now and return expected behavior.
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.
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.
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)
