This commit adds a basic full cluster restart upgrade script that tests
upgrades of elasticsearch across major version. In contrast to the BWC
tests we are running using the java test framework this test uses a python
script as well as the REST APIs to ensure upgrades across major version work and
indices are compatible.
The upgrade test starts 2 or more nodes of an old elasticserach version, indexes
a random number of documents into the running nodes and executes a full cluster restart.
After the nodes are recovered a small set of basic checks are executed to ensure all
documents are still searchable and field data can be loaded etc.
Closes#7074
This commit effectively reverts e1aa91d , as it is not needed anymore to add the original listed nodes. The cluster state local call made will in fact always return at least the local node (see #6811).
There were a couple of downsides caused by putting the original listed nodes among the connected nodes:
1) in the following retries, they weren't seen as listed nodes anymore, thus the light connect wasn't used
2) among the connected nodes some were "bad" duplicates as they are already there and don't contain all needed info for each node. This was causing serialization problems for instance given that the node version was missing on the `DiscoveryNode` object.
Closes#7067
The RetryListener was notified twice for each single failure, which caused some additional retries, but more importantly was making the client reach the maximum number of retries (number of connected nodes) too quickly, meanwhile ongoing retries which could succeed were not completed yet.
The TransportService used to throw ConnectTransportException due to throwConnectException set to true, and also notify the listener of any exception received from a separate thread through the request holder.
Simplified exception handling by just removing the throwConnectException option from the TransportService, used only in the transport client. The transport client now relies solely on the request holder to notify of failures and eventually retry.
Closes#6829
Adds additional version checks in NodeStats for older versions
When using an external cluster (backwards compatibility tests), the act
of checking the request breaker requires a network buffer, which
increments the breaker. This change only checks the request breaker in
InternalTestCluster and uses Guice to retrieve it instead of
a (possible) network request.
Also removed the now unused InternalCircuitBreakerService class
Also improved filter chain tests to not rely on execution time, and made filter chain tests look more similar to what happens in reality by removing multiple threads creation in testTooManyContinueProcessing (something we don't support anyway, makes little sense to test it).
Closes#7021
With commit 07c632a2d4dbefe44e8f25dc4ded6cf143d60e41, we now have a new Lucene.parseVersionLenient(String, Version) method which tries to find an existing Lucene version based on the two first digits X.Y of X.Y.Z String.
Pull Request #7055 fixed Version parsing for bugfix releases
causing problems with minor version in segments files. Even though
we never release anything with lucene in alpha / beta status this
commit fixes lenient parsing for these cases.
Relates to #7055
We parse the version that is shipped with the Lucene segments in order
to find the version of lucene that wrote a particular segment. Yet, some lucene
version ie:
* 4.3.1 (Elasticsearch 0.90.2)
* 4.5.1 (Elasticsearch 0.90.7)
* 3.6.1 (pre Elasticsearch 0.90.0)
wrote illegal strings containing the minor version which causes IAE exceptions
being thrown from lucenes parsing method.
Closes#7055
Adds a breaker for request BigArrays, which are used for parent/child
queries as well as some aggregations. Certain operations like Netty HTTP
responses and transport responses increment the breaker, but will not
trip.
This also changes the output of the nodes' stats endpoint to show the
parent breaker as well as the fielddata and request breakers.
There are a number of new settings for breakers now:
`indices.breaker.total.limit`: starting limit for all memory-use breaker,
defaults to 70%
`indices.breaker.fielddata.limit`: starting limit for fielddata breaker,
defaults to 60%
`indices.breaker.fielddata.overhead`: overhead for fielddata breaker
estimations, defaults to 1.03
(the fielddata breaker settings also use the backwards-compatible
setting `indices.fielddata.breaker.limit` and
`indices.fielddata.breaker.overhead`)
`indices.breaker.request.limit`: starting limit for request breaker,
defaults to 40%
`indices.breaker.request.overhead`: request breaker estimation overhead,
defaults to 1.0
The breaker service infrastructure is now generic and opens the path to
adding additional circuit breakers in the future.

Closes#7001
No that we are using the index created version to make index-time decisions,
assuming that the version is the current version when settings are null is
very error-prone. Instead we should ensure that settings are always non-null
and contain the version when the index was created.

In context of mapper attachment and other mapper plugins, when dealing with multi fields, sub fields never get the `externalValue` although it was set.
Here is a full script which reproduce the issue when used with mapper attachment plugin:
```
DELETE /test
PUT /test
{
"mappings": {
"test": {
"properties": {
"f": {
"type": "attachment",
"fields": {
"f": {
"analyzer": "english",
"fields": {
"no_stemming": {
"type": "string",
"store": "yes",
"analyzer": "standard"
}
}
}
}
}
}
}
}
}
PUT /test/test/1
{
"f": "VGhlIHF1aWNrIGJyb3duIGZveGVz"
}
GET /test/_search
{
"query": {
"match": {
"f": "quick"
}
}
}
GET /test/_search

"query": {
"match": {

}
}
}
GET /test/test/1?fields=f.no_stemming
```

This is only applicable when the order is set to _count. The upper bound of the error in the doc count is calculated by summing the doc count of the last term on each shard which did not return the term. The implementation calculates the error by summing the doc count for the last term on each shard for which the term IS returned and then subtracts this value from the sum of the doc counts for the last term from ALL shards.

This commit adds regular expression support for the allow-origin
header depending on the value of the request `Origin` header.
The existing HttpRequestBuilder is also extended to support the
OPTIONS HTTP method.
Relates #5601Closes#6891
The HTTP client implementation used by the Elasticsearch REST tests is
backed by apache http client instead of a self written helper class,
that uses HttpUrlConnection. This commit removes the old simple HttpClient
class and uses the more powerful and reliable one for all tests.
It also fixes a minor bug, that when sending a 301 redirect, a Location
header needs to be added as well, which was uncovered by the switching
to the new client.
