Ignore any network errors when registering a webhook
notifier during Minio startup sequence. This way server
can be started even if the webhook endpoint is not available
and unreachable.
go fails to build Minio under at least, armv6 and 386 due to some
inconsistencies in the type of one syscall variable in different
architectures. This PR casts that variable to uint64 to achieve
the desired consistency.
This is to comply with S3 behavior, we previously removed
reading `fs.json` for optimization reasons but we have a
reason to believe that providing ETag and using gjson
provides needed benefit of not having to deal with
unmarshalling overhead of golang stdlib.
Fixes#4028
Values of canonicalized query resources should be unescaped before calculating
the signature. This bug is not noticed before because partNumber and uploadID
values in Minio doesn't have characters that need to be escaped.
Separate out validating v/s parsing logic in
isValidLocationConstraint() into parseLocationConstraint()
and isValidLocation()
Additionally also set `X-Amz-Bucket-Region` as part of the
common headers for the clients to fallback on in-case of any
region related errors.
Healing of buckets, objects and incomplete uploads are implemented and
available via admin REST APIs. Additionally, it is available via mc admin
sub-command. The warning is no longer relevant.
Fixes#4030
This is necessary where in certain environments where
cgroup is used to limit memory usage of a container or
a particular process.
GetStats() is used by caching module to figure out the
optimal cacheable size in memory with cgroup limits
what sysinfo reports might not be the right value set
for a given process.
Fixes#4001
public.crt needs sometimes to have a chain certificate, this PR
explains how to construct public.crt when certificate are issued
by a certificate authority.
`disksUnavailable` healStatus constant indicates that a given object
needs healing but one or more of disks requiring heal are offline. This
can be used by admin heal API consumers to distinguish between a
successful heal and a no-op since the outdated disks were offline.
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
go choose the type of cipher needed, if the connection
is coming from clients which do not support forward
secrecy let the go tls handle this automatically based
on tls1.2 specifications.
Fixes#4017
url.Parse() wrongly parses an address of format "address:port"
which is fixed in go1.8. This inculcates a breaking change
on our end. We should fix this wrong usage everywhere so that
migrating to go1.8 eventually becomes smoother.
Previously serverConfigV17 used a global lock that made any instance of
serverConfigV17 depended on single global serverConfigMu.
This patch fixes by having individual lock per instances.
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
provides us.
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
```
minio.exe -C some_dir server dir
```
has stopped working because of lack of handling of
absolute paths for config directory. Always calculate
absolute path for any relative paths on any operating
system.
The following fix converts all config directory relative
paths into absolute paths.
Fixes#3991
We can't use Content-Encoding to verify if `aws-chunked` is set
or not. Just use 'streaming' signature header instead.
While this is considered mandatory, on the contrary aws-sdk-java
doesn't set this value
http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-streaming.html
```
Set the value to aws-chunked.
```
We will relax it and behave appropriately. Also this PR supports
saving custom encoding after trimming off the `aws-chunked`
parameter.
Fixes#3983
* Add configuration parameter "format" for db targets and perform
configuration migration.
* Add PostgreSQL `access` format: This causes Minio to append all events
to the configured table. Prefix, suffix and event filters continue
to be supported for this mode too.
* Update documentation for PostgreSQL notification target.
* 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:
`/tmp/1`, `/tmp/2`, `/tmp/3`, `/tmp/4` are directories used as disks here.
`test` is the bucket, `obj1` and obj2` are the objects.
```
/tmp/1/test
└── obj2
├── part.1
├── part.2
└── xl.json
/tmp/2/test
└── obj1
├── part.1
├── part.2
└── xl.json
/tmp/3/test
├── obj1
│ ├── part.1
│ ├── part.2
│ └── xl.json
└── obj2
├── part.1
├── part.2
└── xl.json
/tmp/4/test
[This is empty]
```
