* Allows for an array of index template patterns to be provided to an
index template, and rename the field from 'template' to 'index_pattern'.
Closes#20690
Applied (almost) the same rules we use to validate index names
to new alias names. The only rule not applies it "must be lowercase".
We have tests that don't follow that rule and I except there are lots
of examples of camelCase alias names in the wild. We can add that
validation but I'm not sure it is worth it.
Closes#20748
Adds an alias that starts with `#` to the BWC index and validates
that you can read from it and remove it. Starting with `#` isn't
allowed after 5.1.0/6.0.0 so we don't create the alias or check it
after those versions.
Adds support for `?slices=N` to reindex which automatically
parallelizes the process using parallel scrolls on `_uid`. Performance
testing sees a 3x performance improvement for simple docs
on decent hardware, maybe 30% performance improvement
for more complex docs. Still compelling, especially because
clusters should be able to get closer to the 3x than the 30%
number.
Closes#20624
Today when writing an unbounded queue_size in the cat thread pool API,
we write null. This commit modifies this so that the output is -1 so
that the output is always present, and always a numeric value.

Exist requests are supposed to never throw an exception, but rather return true or false depending on whether some resource exists or not. Indices exists does that for indices and accepts wildcard expressions too. The way the api works internally is by resolving indices and catching IndexNotFoundException: if an exception is thrown the index does not exist hence it returns false, otherwise it returns true. That works ok only if ignore_unavailable and allow_no_indices indices options are both set to false, meaning that they are strict and any missing index or wildcard expressions that resolves to no indices will lead to an exception that can be thrown and cause false to be returned.
Unfortunately the indices options have been configurable up until now for this request, meaning that one can set ignore_unavailable or allow_no_indices to true and have the indices exist request return true for indices that really don't exist, which makes very little sense in the context of this api.
This commit removes the indicesOptions setter from the IndicesExistsRequest and makes settable only expandWildcardsOpen and expandWildcardsClosed, hence a subset of the available indices options. This way we can guarantee more consistent behaviour of the indices exists api. We can then remove the ignore_unavailable and allow_no_indices option from indices exists api spec
This commit fixes an issue with the cat thread pool API spec. Namely,
the name of the variable for the thread pool patterns parameter was
misnamed in the spec.
Relates #21332
Today we validate the target index name late and therefore don't fail for instance
if the target index already exists and `dry_run=true` was specified. This change
validates the index name before we early terminate if dry_run is set.
Closes#21149
With #21099 we removed support for the ignored allow_no_indices parameter in indices upgrade API. Truth is that ignore_unavailable and expand_wildcards were also ignored, in indices upgrade as well as upgrade status API. Those parameters are though supported internally and settable through java API, hence they should be all supported on the REST layer too.
`FilterAggregationBuilder` today misses to rewrite queries which causes failures
if a query that uses a client for instance to lookup terms since it must be rewritten first.
This change also ensures that if a client is used from the rewrite context we mark the query as
non-cacheable.
Closes#21301
Since we now validate all consumed request parameter, users can't specify
`_cat/nodes?full_id=true|false` anymore since this parameter is consumed late.
This commit adds a test for this parameter and consumes it before request is processed.
Closes#21266
today the `_shrink` tests do relocate all shards to a single node in
the cluster. Yet, that is not always possible since the only node we can
safely identify in the cluster is the master and if the master is a BWC
node in such a cluster we won't be able to relocate shards that have a
primary on the newer version nodes since allocation deciders forbid this.
This change restricts allocation for that index when the index is created
to restrict allocation to the master that guarantees that all primaries
are on the same node which is sufficient for the `_shrink` API to run.
Lucene 6.2 introduces the new `Analyzer.normalize` API, which allows to apply
only character-level normalization such as lowercasing or accent folding, which
is exactly what is needed to process queries that operate on partial terms such
as `prefix`, `wildcard` or `fuzzy` queries. As a consequence, the
`lowercase_expanded_terms` option is not necessary anymore. Furthermore, the
`locale` option was only needed in order to know how to perform the lowercasing,
so this one can be removed as well.
Closes#9978
This fixes our cluster formation task to run REST tests against a mixed version cluster.
Yet, due to some limitations in our test framework `indices.rollover` tests are currently
disabled for the BWC case since they select the current master as the merge node which
happens to be a BWC node and we can't relocate all shards to it since the primaries are on
a higher version node. This will be fixed in a followup.
Closes#21142
Note: This has been cherry-picked from 5.0 and fixes several rest tests
as well as a BWC break in `OsStats.java`
When indices stats are requested via the node stats API, there is a
level parameter to request stats at the index, node, or shards
level. This parameter was not whitelisted when URL parsing was made
strict. This commit whitelists this parameter.
Additionally, there was some leniency in the parsing of this parameter
that has been removed.
Relates #21024
The create request now requires that an ID be present.
Currently the clients hard code a create method, but
we should just add a create REST spec so this method
can be autogenerated.
Today we don't parse alias filters on the coordinating node, we only forward
the alias patters to executing node and resolve it late. This has several problems
like requests that go through filtered aliases are never cached if they use date math,
since the parsing happens very late in the process even without rewriting. It also used
to be processed on every shard while we can only do it once per index on the coordinating node.
Another nice side-effect is that we are never prone to cluster-state updates that change an alias,
all nodes will execute the exact same alias filter since they are process based on the same
cluster state.

Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

This commit changes the default behavior of `_flush` to block if other flushes are ongoing.
This also removes the use of `FlushNotAllowedException` and instead simply return immediately
by skipping the flush. Users should be aware if they set this option that the flush might or might
not flush everything to disk ie. no transactional behavior of some sort.
Closes#20569
Adds a cat api endpoint: /_cat/templates and its more specific version, /_cat/templates/{name}.
It looks something like:
$ curl "localhost:9200/_cat/templates?v"
name template order version
sushi_california_roll *avocado* 1 1
pizza_hawaiian *pineapples* 1
pizza_pepperoni *pepperoni* 1
The specified version (only allows * globs) looks like:
$ curl "localhost:9200/_cat/templates/pizza*"
name template order version
pizza_hawaiian *pineapples* 1
pizza_pepperoni *pepperoni* 1
Partially specified columns:
$ curl "localhost:9200/_cat/templates/pizza*?v=true&h=name,template"
name template
pizza_hawaiian *pineapples*
pizza_pepperoni *pepperoni*
The help text:
$ curl "localhost:9200/_cat/templates/pizza*?help"
name | n | template name
template | t | template pattern string
order | o | template application order number
version | v | version
Closes#20467
We can now run templates using `explain` and/or `profile` parameters.
Which is interesting when you have defined a complicated profile but want to debug it in an easier way than running the full query again.
You can use `explain` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"explain": true
}
```
You can use `profile` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"profile": true
}
```
The command-line arguments for Elasticsearch must now be specified using
-E. This commit fixes the usage of command-line arguments in the REST
API spec README.
The only repository we can be sure is safe to clean is `fs` so we clean
any snapshots in those repositories after each test. Other repositories
like url and azure tend to throw exceptions rather than let us fetch
their contents during the REST test. So we clean what we can....
Closes#18159
The refresh description should indicate that the affected shards are
refreshed as opposed to the entire index.
This was raised as a discrepancy on
discuss (https://discuss.elastic.co/t/refresh-parameter-of-index-api/59008/2)
on the .NET client that originates from code generated from the rest api
spec. The description has been updated in master but should be updated
for the 2.4.0 release.
We put the rest api spec into a jar for upload to maven, so that we can
use within external rest tests. This change adds making a pom for maven
(as well as producing sources and javadoc jars, even though they will be
empty, because maven central requires them).
