Today we have a ton of logic inside the NettyTransport* codebase. The footprint
of the code that has a direct netty dependency is large and alternative implementations
are pretty hard today since they need to know all about our proticol etc.
This change moves most of the code into TCPTransport* baseclasses and moves all
the protocol send code together. The base classes now contain the majority of the logic
while NettyTransport* classes remain to implement the glue code, configuration and optimization.
When GCE region is empty we get back from the API something like:
```
{
"id": "dummy"
}
```
instead of:
```
{
"id": "dummy",
"items":[ ]
}
```
This generates a NPE when we aggregate all the lists into a single one.
Closes#16967.
`RestHandler`s are highly tied to actions so registering them in the
same place makes sense.
Removes the need to for plugins to check if they are in transport client
mode before registering a RestHandler - `getRestHandlers` isn't called
at all in transport client mode.
This caused guice to throw a massive fit about the circular dependency
between NodeClient and the allocation deciders. I broke the circular
dependency by registering the actions map with the node client after
instantiation.
In 2f638b5a23, support for fractional time
values was removed. While this change is documented, the error message
presented does not give an indication that fractional inputs are not
supported. This commit fixes this by detecting when the input is a time
value that would successfully parse as a double but will not parse as a
long and presenting a clear error message that fractional time values
are not supported.
Relates #19158
When doing a `date_histogram` aggregation with `"format":"epoch_millis"` or
`"format" : "epoch_second"` and using a time zone other than UTC, the
`key_as_string` ouput in the response does not reflect the UTC timestamp that is
used as the key. This happens because when applying the `time_zone` in
DocValueFormat.DateTime to an epoch-based formatter, this adds the time zone
offset to the value being formated. Instead we should adjust the added display
offset to get back the utc instance in EpochTimePrinter.
Closes#19038
As some plugins are becoming big now, it is hard for the user to know, if the plugin
is being downloaded or just nothing happens.
This commit adds a progress bar during download, which can be disabled by using the `-q`
parameter.
In addition this updates to jimfs 1.1, which allows us to test the batch mode, as adding
security policies are now supported due to having jimfs:// protocol support in URL stream
handlers.
We have a ton of tests for PagedBytesReference but not really many for the other
implementation of BytesReference. This change factors out a basic AbstractBytesReferenceTestCase
that simplifies testing other implementations. It also caught a couple of bug here and there like
a missing mask when reading bytes as ints in PagedBytesReference.
The ChannelBuffer interface today leaks into the BytesReference abstraction
which causes a hard dependency on Netty across the board. This chance moves
this dependency and all BytesReference -> ChannelBuffer conversion into
NettyUtlis and removes the abstraction leak on BytesReference.
This change also removes unused methods on the BytesReference interface
and simplifies access to internal pages.
This pull request adds two util functions to the Mustache templating engine:
- {{#toJson}}my_map{{/toJson}} to render a Map parameter as a JSON string
- {{#join}}my_iterable{{/join}} to render any iterable (including arrays) as a comma separated list of values like `1, 2, 3`. It's also possible de change the default delimiter (comma) to something else.
closes#18970
This change allows Plugin implementions to implement Closeable when they
have resources that should be released. As a first example of how this
can be used, I switched over ingest plugins, which just had the geoip
processor. The ingest framework had chains of closeable to support this,
which is now removed.
These are useful methods in groovy that give you control over
the replacements used:
```
'the quick brown fox'.replaceAll(/[aeiou]/,
m -> m.group().toUpperCase(Locale.ROOT))
```
Stored scripts are pulled from the cluster state, and the current api
requires passing the ClusterState on each call to compile. However, this
means every user of the ScriptService needs to depend on the
ClusterService. Instead, this change makes the ScriptService a
ClusterStateListener. It also simplifies tests a lot, as they no longer
need to create fake cluster states (except when testing stored scripts).
Today we have several deprecated methods, leaking netty interfaces, support for
multiple compressors on the compressor interface. The netty interface can simply
be replaced by BytesReference which we already have an implementation for, all the
others are not used and are removed in this commit.
It was inadvertently disabled after applying code review comments. This commit reenables the logger usage checker and makes it less naggy when encountering logging usages of the form logger.info(someStringBuilder). Previously it would fail with the error message "First argument must be a string constant so that we can statically ensure proper place holder usage". Now it will only fail in case any arguments are provided as well, for example logger.info(someStringBuilder, 42).
The plan for persistent node ids ( #17811 ) is to tie the node identity to a file stored in it's data folders. As such it becomes important that nodes in our testing infra have better affinity with their data folders and that their data folders are not cleaned underneath them. The first is important because we fix the random seed used for node id generation (for reproducibility) and allowing the same node to use two different data folders causes two separate nodes to have the same id, which prevents the cluster from forming. The second is important, for example, where a full cluster restart / single node restart need to maintain node identity and wiping the data folders at the wrong moment prevents this.
Concretely this commit does the following:
1) Remove previous attempts to have data folder per role using a prefix. This wasn't effective as it was using the data paths settings which are only used for part of the runs. An attempt to completely separate the paths via the home dir failed due to assumptions made by index custom path about node data folder ordinal uniqueness (see #19076)
2) Change full cluster restarts to start up nodes in the same order their were first created in, only randomly swapping nodes with the same roles.
3) Change test cluster reset methods to first shutdown the unneeded nodes and then re-start the shared nodes that were shut down, so they'll reclaim their data folders.
4) Improve data folder wiping logic and make sure it wipes only folders of "offline" nodes.
5) Add some very basic tests
