Upgrade to lucene-7.4.0-snapshot-1ed95c097b
This version contains:
* An Analyzer for Korean
* An IntervalQuery and IntervalsSource that retrieve minimum intervals of positional queries.
* A new API to retrieve matches (offsets and positions) of a query for a single document.
* Support for soft deletes in the index writer.
* A fixed shingle filter that handles index time synonyms.
* Support for emoji sequence in ICUTokenizer (with an upgrade to icu 61.1)
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
Many tests are added with a version check so that they do not run against a
version that doesn't have the feature yet. Master is 7.0, so all tests that
do not run against 6.0+ can be removed and the version check can be removed
on all tests that always run on 6.0+.
Adds two new methods to `RestClient` that take a `Request` object. These
methods will allows us to add more per-request customizable options
without creating more and more and more overloads of the `performRequest`
and `performRequestAsync` methods. These new methods look like:
```
Response performRequest(Request request)
```
and
```
void performRequestAsync(Request request, ResponseListener responseListener)
```
This change doesn't add any actual features but enables adding things like
per request timeouts and per request node selectors. This change *does*
rework the `HighLevelRestClient` and its tests to use these new `Request`
objects and it does update the docs.
We disable the reindex-from-old tests if we're running on windows or in
a directory that contains a space. This adds a warning to the logs when
we do that so that you can tell that it happened. This will be nice to
have when looking at CI and will be a hint to anyone developing locally.
This *mostly* silences `javadoc`'s warning about defaulting to
generating html4 files by enabling generating html5 file for the
projects for which that works. It didn't work in a half dozen projects,
about half of which I've fixed in this PR, entirely by replacing
`<tt>thing</tt>` with `{@code thing}`.
There are a few remaining projects that contain javadoc with invalid
html5. I'll fix those projects in a followup.
We *think* that #28600 is caused by warnings not being collected during
one of the fan out phases of search but we're not 100% sure how this is
happening. This commit drops the number of shards used for the test to 1
so there *isn't* a fan out phase. If this makes the issue go away we'll
have more information.
This folds the `:qa:reindex-from-old` project into the `:modules:reindex`
project. This should speed up the build marginally by removing a single
clsuter start up at the cost of having to wait for old versions of
Elasticsearch to start up when checking reindex's integration tests.
Those don't take that long so this feels worth it.
The ranking evaluation requests so far were not tested against aliases
but they should run regardless of the targeted index is a real index or
an alias. This change adds cases for this to the integration and rest
tests.
The camel case name `htmlStip` should be removed in favour of `html_strip`, but
we need to deprecate it first. This change adds deprecation warnings for indices
with version starting with 6.3.0 and logs deprecation warnings in this cases.
Allow high level java rest client to access details of the metric
calculation by making them accessible across packages. Also renaming the
inner `Breakdown` classes of the evaluation metrics to `Detail` to
better communicate their use.
This commit renames the bulk thread pool to the write thread pool. This
is to better reflect the fact that the underlying thread pool is used to
execute any document write request (single-document index/delete/update
requests, and bulk requests).
With this change, we add support for fallback settings
thread_pool.bulk.* which will be supported until 7.0.0.
We also add a system property so that the display name of the thread
pool remains as "bulk" if needed to avoid breaking users.
Added an api that allows to execute an arbitrary script and a result to be returned.
```
POST /_scripts/painless/_execute
{
"script": {
"source": "params.var1 / params.var2",
"params": {
"var1": 1,
"var2": 1
}
}
}
```

This allows the grammar to determine when and what delimiters statements will use by
splitting up the statements into regular statements and delimited statements, those that do
not require a delimiter versus those that do. This allows consumers of the statements to
determine what delimiters the statements will use so that in certain cases semicolons are
not necessary like when there's a closing right bracket.
This change removes the need for semicolon insertion in the lexer, simplifying the existing
lexer quite a bit. It also ensures that there isn't a need to track semicolons being inserted
into places that aren't necessary such as array initializers.
This change removes the check for extra tokens when parsing a source generated by a templated
_msearch request. This was added unintentionally in #29428 but the intent of this modification was to validate
simple _search request only.
This change validates that the `_search` request does not have trailing
tokens after the main object and fails the request with a parsing exception otherwise.
Closes#28995
Some features have been deprecated since `6.0` like the `_parent` field or the
ability to have multiple types per index. This allows to remove quite some
code, which in-turn will hopefully make it easier to proceed with the removal
of types.
In the case that a document with a percolator field is matched when using the `percolate` query then
the fetch phase can fail due to the fact that the percolator can't resolve any query from that document.
Closes#29429
In case of a disjunction query with both range and term based clauses and
msm specified, the query analyzer needs to also reduce the msn if a range
based clause for the same field is encountered. This did not happen.
Instead of fixing this bug the logic has been simplified to just set a
percolator query's msm to 1 if a disjunction contains range clauses and
msm on disjunction has been specified. The logic would otherwise just get
to complex and the performance gain isn't that much for this kind of
percolator queries.
In case a percolator query has clauses that have duplicate terms or ranges then
for disjunction clauses with a minimum should match the query extraction of the
clause with the lowest msm should be used and for conjunction queries query
extractions wiht duplicate terms/ranges the msn should be ignored. If this
is not done then percolator queries that should match never match.
Example percolator query: value1 OR value2 OR value2 OR value3 OR value3 OR value3 OR value4 OR value5 (msm set to 3)
In the above example query the extracted msm would be 3
Example document1: value1 value2 value3
With the msm and extracted terms this would match and is expected behaviour
Example document2: value3
This document should match too (value3 appears in 3 clauses), but with msm set to 3 and the fact
that fact that only distinct values are indexed in extracted terms field this document would
Also added another random duel test.
Closes#29393
This change tries to simplify the extraction logic of boolean queries by
concentrating the logic into two methods: one that merges results for
conjunctions, and another one for disjunctions. Other concerns, like the impact
of prohibited clauses or how an `UnsupportedQueryException` should be treated
are applied on top of those two methods.
This is mostly a code reorganization, it doesn't change the result of query
extraction except in the case that a query both has required clauses and a
minimum number of `SHOULD` clauses that is greater than 1, which we now
rewrite into a pure conjunction. For instance `(+A B C)~1` is rewritten into
`(+A +(B C))` prior to extraction.
* Move ObjectParser into the x-content lib
This moves `ObjectParser`, `AbstractObjectParser`, and
`ConstructingObjectParser` into the libs/x-content dependency. This decoupling
allows them to be used for parsing for projects that don't want to depend on the
entire Elasticsearch jar.

Currently the ranking evaluation API doesn't support many of the
standard parameters of the search API. Some of these make sense, like
adding support for the common indices options parameters, which this
change adds.
I found the following bugs:
- The 6.0 logic for conjunctions didn't work when there were only `match_all`
queries in MUST/FILTER clauses as they didn't propagate the `matchAllDocs`
flag.
- Some queries still had the same issue as `BooleanQuery` used to have with
duplicate terms (see #28353), eg. `MultiPhraseQuery`.
Closes#29376
From 7.0 on, using `delimited_payload_filter` should throw an error.
It was deprecated in 6.2 in favour of `delimited_payload` (#26625).

This commit adds a YAML integration test for the repository-url module
that uses a fixture to test URL based repositories on both http:// and
file:// prefixes.
This improves the way similarities are plugged in in order to:
- reject the classic similarity on 7.x indices and emit a deprecation
warning otherwise
- reject unkwown parameters on 7.x indices and emit a deprecation
warning otherwise
Even though this breaks the plugin API, I'd like to backport to 7.x so
that users can get deprecation warnings when they are doing something
that will become unsupported in the future.
Closes#23208Closes#29035
While playing with the percolator I found two bugs:
- Sometimes we set a min_should_match that is greater than the number of
extractions. While this doesn't cause direct trouble, it does when the query
is nested into a boolean query and the boolean query tries to compute the
min_should_match for the entire query based on its own min_should_match and
those of the sub queries. So I changed the code to throw an exception when
min_should_match is greater than the number of extractions.
- Boolean queries claim matches are verified when in fact they shouldn't. This
is due to the fact that boolean queries assume that they are verified if all
sub clauses are verified but things are more complex than that, eg.
conjunctions that are nested in a disjunction or disjunctions that are nested
in a conjunction can generally not be verified without running the query.
Fixes and edge case where DiscountedCumulativeGain can return NaN as
result of the quality metric calculation. This can happen when the
search result set is empty and normalization is used. We should return 0
in this case. Also adding related unit tests to the other two metrics.
I am not sure why we have this leniency for HTTP max content length, it
has been there since the beginning
(5ac51ee93f) with no explanation of its
source. That said, our philosophy today is different than the philosophy
of the past where Elasticsearch would be quite lenient in its handling
of settings and today we aim for predictability for both users and
us. This commit removes leniency in the parsing of
http.max_content_length.
* Begin moving XContent to a separate lib/artifact
This commit moves a large portion of the XContent code from the `server` project
to the `libs/xcontent` project. For the pieces that have been moved, some
helpers have been duplicated to allow them to be decoupled from ES helper
classes. In addition, `Booleans` and `CheckedFunction` have been moved to the
`elasticsearch-core` project.
This decoupling is a move so that we can eventually make things like the
high-level REST client not rely on the entire ES jar, only the parts it needs.
There are some pieces that are still not decoupled, in particular some of the
XContent tests still remain in the server project, this is because they test a
large portion of the pluggable xcontent pieces through
`XContentElasticsearchException`. They may be decoupled in future work.
Additionally, there may be more piecese that we want to move to the xcontent lib
in the future that are not part of this PR, this is a starting point.

We use a latch when sending requests during tests so that we do not hang
forever waiting for replies on those requests. This commit increases the
timeout on that latch to 30 seconds because sometimes 10 seconds is just
not enough.
Today we have a few problems with how we handle bad requests:
- handling requests with bad encoding
- handling requests with invalid value for filter_path/pretty/human
- handling requests with a garbage Content-Type header
There are two problems:
- in every case, we give an empty response to the client
- in most cases, we leak the byte buffer backing the request!
These problems are caused by a broader problem: poor handling preparing
the request for handling, or the channel to write to when the response
is ready. This commit addresses these issues by taking a unified
approach to all of them that ensures that:
- we respond to the client with the exception that blew us up
- we do not leak the byte buffer backing the request
In 5.2 `ignore_unmapped` was added to `inner_hits` in order to ignore invalid mapping.
This value was automatically set to the value defined in the parent query (`nested`, `has_child`, `has_parent`) but the refactoring of the parent/child in 5.6 removed this behavior unintentionally.
This commit restores this behavior but also makes sure that we always automatically enforce this value when the query builder is used directly (previously this was only done by the XContent deserialization).
