Harshavardhana bfb505aa8e Refactor logging in more Go idiomatic style (#6816)
This refactor brings a change which allows
targets to be added in a cleaner way and also
audit is now moved out.

This PR also simplifies logger dependency for auditing

Harshavardhana a55a298e00 Make sure to log unhandled errors always (#6784)
In many situations, while testing we encounter
ErrInternalError, to reduce logging we have
removed logging from quite a few places which
is acceptable but when ErrInternalError occurs
we should have a facility to log the corresponding
error, this helps to debug Minio server.

Harshavardhana b0c9ae7490 Add audit logging for S3 and Web handlers (#6571)
This PR brings an additional logger implementation
called AuditLog which logs to http targets

The intention is to use AuditLog to log all incoming
requests, this is used as a mechanism by external log
collection entities for processing Minio requests.

kannappanr 76ddf4d32f Log x-amz-request-id as log and XML error response (#6173)
Currently, requestid field in logEntry is not populated, as the
requestid field gets set at the very end.
It is now set before regular handler functions. This is also
useful in setting it as part of the XML error response.

Travis build for ppc64le has been quite inconsistent and stays queued
for most of the time. Removing this build as part of Travis.yml for
the time being.

Harshavardhana b6ca39ea48 Support migrating inconsistent bucket policies (#5855)
Previously we used allow bucket policies without
`Version` field to be set to any given value, but
this behavior is inconsistent with AWS S3.

PR #5790 addressed this by making bucket policies
stricter and cleaner, but this causes a breaking
change causing any existing policies perhaps without
`Version` field or the field to be empty to fail upon
server startup.

This PR brings a code to migrate under these scenarios
as a one time operation.

Bala FA 0d52126023 Enhance policy handling to support SSE and WORM (#5790)
- remove old bucket policy handling
- add new policy handling
- add new policy handling unit tests

This patch brings support to bucket policy to have more control not
limiting to anonymous.  Bucket owner controls to allow/deny any rest
API.

For example server side encryption can be controlled by allowing
PUT/GET objects with encryptions including bucket owner.

Krishna Srinivas 14e6c5ec08 Simplify the steps to make changes to config.json (#5186)
This change introduces following simplified steps to follow 
during config migration.

```
 // Steps to move from version N to version N+1
 // 1. Add new struct serverConfigVN+1 in config-versions.go
 // 2. Set configCurrentVersion to "N+1"
 // 3. Set serverConfigCurrent to serverConfigVN+1
 // 4. Add new migration function (ex. func migrateVNToVN+1()) in config-migrate.go
 // 5. Call migrateVNToVN+1() from migrateConfig() in config-migrate.go
 // 6. Make changes in config-current_test.go for any test change

Harshavardhana 533338bdeb all/windows: Be case in-sensitive about pattern matching. (#3682)
Resource strings and paths are case insensitive on windows
deployments but if user happens to use upper case instead of
lower case for certain configuration params like bucket
policies and bucket notification config. We might not honor
them which leads to a wrong behavior on windows.

This is windows only behavior, for all other platforms case
is still kept sensitive.

Harshavardhana 51fa4f7fe3 Make PutObject a nop for an object which ends with "/" and size is '0' (#3603)

Harshavardhana 926c75d0b5 api: Set appropriate content-type for success/error responses. (#3537)
Golang HTTP client automatically detects content-type but
for S3 clients this content-type might be incorrect or
might misbehave.

For example:

```
Content-Type: text/xml; charset=utf-8
```

Should be
```
Content-Type: application/xml
```

Allow this to be set properly.

Harshavardhana 4daa0d2cee lock: Moving locking to handler layer. (#3381)
This is implemented so that the issues like in the
following flow don't affect the behavior of operation.

```
GetObjectInfo()
.... --> Time window for mutation (no lock held)
.... --> Time window for mutation (no lock held)
GetObject()
```

This happens when two simultaneous uploads are made
to the same object the object has returned wrong
info to the client.

Another classic example is "CopyObject" API itself
which reads from a source object and copies to
destination object.

* Avoid nested if in bucketPolicyMatchStatement()
* Use ioutil.ReadFile() instead of os.Open() and ioutil.ReadAll()
* Set crossDomainXML as constant.

Aditya Manthramurthy dd0698d14c Improve namespace lock API: (#3203)
- abstract out instrumentation information.

Aditya Manthramurthy 3977d6b7bd Lock bucket while modifying its metadata (Fixes #2979) (#3019)
- When modifying notification configuration
- When modifying listener configuration
- When modifying policy configuration

With this change we also stop early checking if the bucket exists, since
that uses a Read-lock and causes a deadlock due to the outer Write-lock.

Harshavardhana 975eb31973 api/bucketPolicy: Use minio-go/pkg/set and fix bucket policy regression. (#2506)
Current master has a regression 'mc policy <policy-type> alias/bucket/prefix'
does not work anymore, due to the way new minio-go changes do json marshalling.
This led to a regression on server side when a ``prefix`` is provided
policy is rejected as malformed from th server which is not the case with
AWS S3.

This patch uses the new ``minio-go/pkg/set`` package to address the
unmarshalling problems.
