We don't need to typecast identifiers from
their base to type to same type again. This
is not a bug and compiler is fine to skip
it but it is better to avoid if not needed.
This change provides new implementations of the XL backend operations:
- create file
- read file
- heal file
Further this change adds table based tests for all three operations.
This affects also the bitrot algorithm integration. Algorithms are now
integrated in an idiomatic way (like crypto.Hash).

Wait for remote hosts to resolve instead of failing on first host
resolution error, when running in Kubernetes or Docker environment.
Note that
- Waiting is based on exponential back-off mechanism
- If run as a binary, server fails if remote host is not resolvable
This is needed because in orchestration platforms like Kubernetes, remote
hosts are started sequentially and all the hosts are not up initially,
though they are expected to come up in a short time frame
It is difficult to identify a cap on the waiting time due to
non-deterministic nature of infrastructure platforms, so the server waits
infinitely for the hosts to come up, while logging the error messages to
the console.

Since go1.8 os.RemoveAll and os.MkdirAll both support long
path names i.e UNC path on windows. The code we are carrying
was directly borrowed from `pkg/os` package and doesn't need
to be in our repo anymore. As a side affect this also
addresses our codecoverage issue.

* Prevent unnecessary verification of parity blocks while reading erasure
coded file.
* Update klauspost/reedsolomon and just only reconstruct data blocks while
reading (prevent unnecessary parity block reconstruction)
* Remove Verification of (all) reconstructed Data and Parity blocks since
in our case we are protected by bit rot protection. And even if the
verification would fail (essentially impossible) there is no way to
definitively say whether the data is still correct or not, so this call
make no sense for our use case.
Implement an offline mode for remote storage to cache the

Existing code was written in a manner where say
a bucket/top-level directory was indeed deleted
between Readdir() and before StatDir() we would
ignore certain errors. This is not a plausible
situation and might not happen in almost all
practical cases. We do not have to look for
or interpret these errors returned by StatDir()
instead we can just collect the successful
values and return back to the client. We do not
need to pre-maturely decide on bucket access
we just let filesystem decide subsequently for
real I/O operations.

This commit changes posix's deleteFile() to not upstream errors from
removing parent directories. This fixes a race condition.
The race condition occurs when multiple deleteFile()s are called on the
same parent directory, but different child files. Because deleteFile()
recursively removes parent directories if they are empty, but
deleteFile() errors if the selected deletePath does not exist, there was
an opportunity for a race condition. The two processes would remove the
child directories successfully, then depend on the parent directory
still existing. In some cases this is an invalid assumption, because
other processes can remove the parent directory beforehand. This commit
changes deleteFile() to not upstream an error if one occurs, because the
only required error should be from the immediate deletePath, not from a
parent path.
In the specific bug report, multiple CompleteMultipartUpload requests
would launch multiple deleteFile() requests. Because they chain up on
parent directories, ultimately at the end, there would be multiple
remove files for the ultimate parent directory,
.minio.sys/multipart/{bucket}. Because only one will succeed and one
will fail, an error would be upstreamed saying that the file does not
exist, and the CompleteMultipartUpload code interpreted this as
NoSuchKey, or that the object/part id doesn't exist. This was faulty
behavior and is now fixed.
The added test fails before this change and passes after this change.
Fixes: https://github.com/minio/minio/issues/4727
This commit adds a new test for isDirEmpty (for code coverage) and
changes around the error conditional. Previously, there was a `return
nil` statement that would only be triggered under a race condition and
would trip up our test coverage for no real reason. With this new error
conditional, there's no awkward 'else'-esque condition, which means test
coverage will not change between runs for no reason in this specific
test. It's also a cleaner read.
This commit makes fsDeleteFile() simply call deleteFile() after calling
the relevant path length checking functions. This DRYs the code base.
This commit removes the Stat() call from deleteFile(). This improves
performance and removes any possibility of a race condition.
This additionally adds tests and a benchmark for said function. The
results aren't very consistent, although I'd expect this commit to make
it faster.
This commit fixes a potential security issue, whereby a full-access
token to the server would be available in the GET URL of a download
request. This fixes that issue by introducing short-expiry tokens, which
are only valid for one minute, and are regenerated for every download
request.
This commit specifically introduces the short-lived tokens, adds tests
for the tokens, adds an RPC call for generating a token given a
full-access token, updates the browser to use the new tokens for
requests where the token is passed as a GET parameter, and adds some
tests with the new temporary tokens.

Fixes#4494#4476 & fixed review comments
This PR serves to fix following things in GCS gateway.
- fixes leaks in object reader and writer, not getting closed
under certain situations. This led to go-routine leaks.
- apparent confusing issue in case of complete multipart upload,
where it is currently possible for an entirely different
object name to concatenate parts of a different object name
if you happen to know the upload-id and parts of the object.
This is a very rare scenario but it is possible.
- succint usage of certain parts of code base and re-use.
Fixed header-to-metadat extraction. The extractMetadataFromHeader function should return an error if the http.Header contains a non-canonicalized key. The reason is that the keys can be manually set (through a map access) which can lead to ugly bugs.
Also fixed header-to-metadata extraction. Return a InternalError if a non-canonicalized key is found in a http.Header. Also log the error.
This is needed to avoid proxies buffering the connection
this is also a HTTP standard way to handle this situation
where server is sending back events in asynchronously.

When the browser asks for a GET presigned url, this latter is not
encoded and can be confusing when the user copies-pastes it somewhere,
especially when the path contains a space.
Current state-machine didn't honor a situation
which can arise when there is a combination of
- formatted
- unformatted
- corrupted
disks - this combination invariably goes into a
mode where all servers are waiting perpetually
forever thinking we will get quorum in future.
At this point there is a distant possibility of
ever getting a quorum since we don't even have
quorum number of disks offline.
We should exit and print a proper message per disk
to indicate what went wrong and what was detected
by the server.

This implementation is similar to AMQP notifications:
* Notifications are published on a single topic as a JSON feed
* Topic is configurable, as is the QoS. Uses the paho.mqtt.golang
library for the mqtt connection, and supports connections over tcp

* Additionally the minio server configuration has been bumped up
so mqtt configuration can be added.
* Configuration migration code is added with tests.

xl.storageDisks is sometimes passed to some low-level XL functions. Some disks in
xl.storageDisks are set to nil when they encounter some errors. This means all
elements in xl.storageDisks will be nil after some time which lead to an unusable XL.

Go can potentially kick in GC and close the fd when
the reference is lost, only speculation is that
the cause here is `SetFinalizer` which is set on
`os.close()` internally in `os` stdlib.
This is unexpected and unsual endeavour for Go, but
we have to make sure the reference is never lost
and always dies with the server.

Sending envVars along with access and secret
exposes the entire minio server's sensitive

not the entire set of system envs.
This is an enhancement to the XL/distributed-XL mode. FS mode is
unaffected.
The ReadFileWithVerify storage-layer call is similar to ReadFile with
the additional functionality of performing bit-rot checking. It
accepts additional parameters for a hashing algorithm to use and the
expected hex-encoded hash string.
This patch provides significant performance improvement because:
1. combines the step of reading the file (during
erasure-decoding/reconstruction) with bit-rot verification;
2. limits the number of file-reads; and
3. avoids transferring the file over the network for bit-rot
verification.
ReadFile API is implemented as ReadFileWithVerify with empty hashing
arguments.

Fix this by using proper formatting directive.
Duration for which a lock was held can be computed from the `Since`

time at which the namespace lock was held. This change avoids
superfluous instrumentation.
Previous value was set to avoid large cache value build
up but we can clearly see this can cause lots of GC
pauses which can lead to significant drop in performance.
Change this value to 50% and decrease the value to 25%

window for GC pauses.
Another change is to only allow caching if a server has
more than 24GB of RAM instead of 8GB.
Such that in a situation where all errors were

For example in a 6 disk setup 1 disk is missing
and 5 do not have the volume (testbucket)
Without this change Stat() would result in different
errors depending on which disk died. Can cause
confusion to S3 client application.
This change addresses need to track type of
errors we ignored and bring readQuorum to
choose the maximally occuring as the value
of truth.
getBucketInfo() should keep track errors ignored,
such that in a situation where all errors were
ignored we need to reduce the errors using readQuorum
to get a consistent error value.
This is the problem we see with DiskNotFound test
disks are randomly removed.

`disksUnavailable` healStatus constant indicates that a given object

This change adds `access` format support for notifications to a
Elasticsearch server, and it refactors `namespace` format support.
In the case of `access` format, for each event in Minio, a JSON
document is inserted into Elasticsearch with its timestamp set to the
event's timestamp, and with the ID generated automatically by
elasticsearch. No events are modified or deleted in this mode.
In the case of `namespace` format, for each event in Minio, a JSON
document is keyed together by the bucket and object name is updated in
Elasticsearch. In the case of an object being created or over-written
in Minio, a new document or an existing document is inserted into the
Elasticsearch index. If an object is deleted in Minio, the
corresponding document is deleted from the Elasticsearch index.
Additionally, this change upgrades Elasticsearch support to the 5.x
series. This is a breaking change, and users of previous elasticsearch
versions should upgrade.
Also updates documentation on Elasticsearch notification target usage
and has a link to an elasticsearch upgrade guide.
This is the last patch that finally resolves#3928.
Do not rely on a specific cipher suite instead let the

Previously serverConfigV17 used a global lock that made any instance of

This is an enhancement change to to cater support all
the data fields present on the object. Currently
we only send a subset of data which object info

It also helps us keep a full namespace mirror on
notification targets for efficient query.
CopyObjectHandler() was incorrectly performing comparison
between destination and source object paths, which sometimes
leads to a lock race. This PR simplifies comparaison and add
one test case.
This change adds `access` format support for notifications to a Redis
server, and it refactors `namespace` format support.
In the case of `access` format, a list is used to store Minio
operations in Redis. Each entry in the list is a JSON encoded list of
two items - the first is the Minio server timestamp of the event, and
the second is an object describing the operation that created/replaced
the object in the server.
In the case of `namespace` format, a hash is used. Entries in the hash
may be updated or removed if objects in Minio are updated or deleted
respectively. The field values in the Redis hash are JSON encoded.
Also updates documentation on Redis notification target usage.
Towards resolving #3928
The following form of arguments such as

* Add MySQL `access` format: It is very similar to the same format for
PostgreSQL.
* Update MySQL notification documentation.
Statically typed BrowserFlag prevents any arbitrary string value
usage. The wrapped bool marshals/unmarshals JSON according to the
typed value ie string value "on" represents boolean true and "off" as
boolean false.
This is to keep the portability and also avoid errors that
might occur using the functions written for URL resource name
Since query param values have different escaping requirements.
In the algorithm to check if an object requires healing, in addition to
checking if all disks have xl.json present we should check if all parts
of the object are present and have valid blake2b checksums.
Also fixed a minor compilation error in heal-objects-list.go.
This patch fixes below
* Previously fatalIf() never writes log other than first logging target.
* quiet flag is not honored to show progress messages other than startup messages.
* Removes console package usage for progress messages.
For listing of objects needing heal, we list all objects present on all
the disks and return the set union. We were incorrectly dropping objects
that weren't already seen in disks so far.
Sample directory layout of disks in a 4-disk setup:

This change adds information like host, port and user-agent of the
client whose request triggered an event notification.
E.g, if someone uploads an object to a bucket using mc. If notifications
were configured on that bucket, the host, port and user-agent of mc
would be sent as part of event notification data.
Sample output:
```
"source": {
"host": "127.0.0.1",
"port": "55808",
"userAgent": "Minio (linux; amd64) minio-go/2.0.4 mc ..."

* Add a new function Save() which saves given configuration into given file.
* Simplify Load() function.
* Remove unused CheckVersion().
* CheckData() is a private function now.
* quick_test.go is part of quick package now.
* minio server uses top level quick.Load() and quick.Save() functions.
Previously, erasure backend's `listDirFactory` may return errors which
were explicitly ignored. With this change, it returns nil. Superfluous
checks at higher-layers for ignored errors are removed as well.
As a new configuration parameter is added, configuration version is
bumped up from 14 to 15.
The MySQL target's behaviour is identical to the PostgreSQL: rows are
deleted from the MySQL table on delete-object events, and are
created/updated on create/over-write events.
This API is meant for administrative tools like mc-admin to heal an
ongoing multipart upload on a Minio server. N B This set of admin
APIs apply only for Minio servers.
`github.com/minio/minio/pkg/madmin` provides a go SDK for this (and
other admin) operations. Specifically,
func HealUpload(bucket, object, uploadID string, dryRun bool) error
Sample admin API request:
POST
/?heal&bucket=mybucket&object=myobject&upload-id=myuploadID&dry-run
- Header(s): ["x-minio-operation"] = "upload"
Notes:
- bucket, object and upload-id are mandatory query parameters
- if dry-run is set, API returns success if all parameters passed are
valid.
checkURL() is a generic function to check if a passed address
is valid. This commit adds support for addresses like `m1`
and `172.16.3.1` which is needed in MySQL and NATS. This commit
also adds tests.
HEAD Object for FS and XL was returning invalid object name when
an object name has a trailing slash separator, this PR changes the
behavior and will always return 404 object not found, this guarantees
a better compatibility with S3 spec.
This change is cleanup of the postPolicyHandler code
primarily to address the flow and also converting
certain critical parts into self contained functions.
It was possible to upload a big file which overcomes the minimal
disk space limit in XL, PrepareFile was actually checking for disk
space but we weren't checking its returned error. This patch fixes
this behavior.
* fs: Rename tempObjPath variable in fsCreateFile()
* fs/posix: Factor checkDiskFree() function
* fs: Add disk free check in fsCreateFile()
* posix: Move free disk check to createFile()
* xl: Relax free disk check in POSIX initialization
* fs: checkDiskFree checks for space to store data
This improves the startup time significantly
for clusters which have lot of buckets.
Also fixes a bug where `.minio.sys` is created
on disks which do not have `format.json`
startOffset was re-assigned to '0' so it would end up
copying wrong content ignoring the requested startOffset.
This also fixes the corruption issue we observed while
using docker registry.
Fixes https://github.com/docker/distribution/issues/2205
Also fixes#3842 - incorrect routing.
The globalMaxObjectSize limit is instilled in S3 spec perhaps
due to certain limitations on S3 infrastructure. For minio we
don't have such limitations and we can stream a larger file
instead.
So we are going to bump this limit to 16GiB.
Fixes#3825
This function was returning BucketNotFound for all errors
which at least hides the fact that disks could be corrupted.
This commit fixes the behavior by returning all errors that,

Here are the list of checks for time as they happen
- Fresh connect (during server startup) - CORRECT
- A reconnect after network disconnect - CORRECT
- For each RPC call - INCORRECT.
Verifying time for each RPC aggravates a situation

due to enough load on a production setup. 3 second
might not be enough time window for the call to be

Ref #3784
Content-Encoding is set to "aws-chunked" which is an S3 specific
API value which is no meaning for an object. This is how S3
behaves as well for a streaming signature uploaded object.
Make sure to skip reserved bucket names in `ListBuckets()`
current code didn't skip this properly and also generalize
this behavior for both XL and FS.
This is an attempt cleanup code and keep the top level config
functions simpler and easy to understand where as move the
notifier related code and logger setter/getter methods as part
of their own struct.
Locks are now held properly not globally by configMutex, but
instead as private variables.
Final fix for #3700
Also changes the behavior of `secretKeyHash` which is
not necessary to be sent over the network, each node
has its own secretKeyHash to validate.
Fixes#3696
Partial(fix) #3700 (More changes needed with some code cleanup)
Currently the auth rpc client defaults to to a maximum
cap of 30seconds timeout. Make this to be configurable
by the caller of authRPCClient during initialization, if no
such config is provided then default to 30 seconds.
Ideally here if the interface is not found it would
fail the server, as it should be because without these
we can't even have a working server in the first place.
Just like how it fails in master invariably inside Go
net/http code path.
Fixes#3708
