* LeafCollector.setScorer() now takes a Scorable
* Scorers may not have null Weights
* IndexWriter.getFlushingBytes() reports how much memory is being used by IW threads writing to disk
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
The upcoming ML log structure finder functionality will use these
libraries, and it makes sense to use the same versions that are
being used elsewhere in Elasticsearch. This is especially true
with icu4j, which is pretty big.
The main highlight is the removal of the reclaim_deletes_weight in the TieredMergePolicy.
The es setting index.merge.policy.reclaim_deletes_weight is deprecated in this commit and the value is ignored. The new merge policy setting setDeletesPctAllowed should be added in a follow up.
This snapshot includes:
- LUCENE-8341: Record soft deletes in SegmentCommitInfo which will resolve#30851
- LUCENE-8335: Enforce soft-deletes field up-front
The new snapshot includes LUCENE-8324 which fixes missing checkpoint
after a fully deletes segment is dropped on flush. This snapshot should
resolves failed tests in the CorruptedFileIT suite.

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 new snapshot mostly brings a change to TopFieldCollector which can now
early terminate collection when trackTotalHits is `false`.
As a follow-up, we should replace our usage of
`EarlyTerminatingSortingCollector` with this new option.
The main highlight of this new snapshot is that it introduces the opportunity
for queries to opt out of caching. In case a query opts out of caching, not only
will it never be cached, but also no compound query that wraps it will be
cached.
While it's not possible to upgrade the Jackson dependencies
to their latest versions yet (see #27032 (comment) for more)
it's still possible to upgrade to the latest 2.8.x version.
Upgrade to Jackson 2.9.2 and also use a boolean `closed` flag to
indicate that a FastStringReader instance is closed, so that length
is still correctly reported after the reader is closed.
There is a bug in Log4j on JDK 9 for walking the stack to find where a
log line is coming from. This bug is impacting some of our testing, so
this commit marks these tests as skippable only on JDK 9 until the bug
is fixed upstream.

In some cases our Windows builds fail due to long path names that arise
from a combination of long build job names plus long sub-project
names. While newer versions of Windows can handle long paths, invoking
batch scripts longer than 260 characters via cmd.exe is still
problematic. This leads to failing integration tests because we can not
run the commands to install plugins, create the keystore, and start the
node. This commit handles this by converting all paths on Windows used
to start an Elasticsearch node to short path names.

This commit updates the version for master to 7.0.0-alpha1. It also adds
the 6.1 version constant, and fixes many tests, as well as marking some
as awaits fix.
Closes#25893Closes#25870
This commit does two things:
- bumps the version from 6.0.0-alpha3 to 6.0.0-beta1
- renames the 6.0.0-alpha3 version constant to 6.0.0-beta1

This commit introduces a nio based tcp transport into framework for
testing.
Currently Elasticsearch uses a simple blocking tcp transport for
testing purposes (MockTcpTransport). This diverges from production
where our current transport (netty) is non-blocking.
The point of this commit is to introduce a testing variant that more
closely matches the behavior of production instances.
Most notable changes:
- better update concurrency: LUCENE-7868
- TopDocs.totalHits is now a long: LUCENE-7872
- QueryBuilder does not remove the boolean query around multi-term synonyms:
LUCENE-7878
- removal of Fields: LUCENE-7500
For the `TopDocs.totalHits` change, this PR relies on the fact that the encoding
of vInts and vLongs are compatible: you can write and read with any of them as
long as the value can be represented by a positive int.
This snapshot has faster range queries on range fields (LUCENE-7828), more
accurate norms (LUCENE-7730) and the ability to use fake term frequencies
(LUCENE-7854).
