This option defaults to false, because it is also important to upgrade
the "merely old" segments since many Lucene improvements happen within
minor releases.
But you can pass true to do the minimal work necessary to upgrade to
the next major Elasticsearch release.
The HTTP GET upgrade request now also breaks out how many bytes of
ancient segments need upgrading.

We have two completely different code paths for mappings updates, depending on
whether they come from the API or are guessed based on the parsed documents.
This commit makes dynamic mappings updates execute like updates from the API.
The only change in behaviour is that a document that fails parsing can not
modify mappings anymore (useful to prevent issues such as #9851). Other than
that, this change should be fairly transparent to users but working this way
opens doors to other changes such as validating dynamic mappings updates on the
master node (#8688).
The way it works internally is that Mapper.parse now returns a Mapper instead
of being void. The returned Mapper represents a mapping update that has been
performed in order to parse the document. Mappings updates are propagated
recursively back to the root mapper, and once parsing is finished, we check
that the mappings update can be applied, and either fail the parsing if the
update cannot be merged (eg. because of a concurrent mapping update from the
API) or merge the update into the mappings.
However not all mappings updates can be applied recursively, `copy_to` for
instance can add mappings at totally different places in the tree. Because of
it I added ParseContext.rootMapperUpdates which `copy_to` fills when the
field to copy data to does not exist in the mappings yet. These mappings
updates are merged from the ones generated by regular parsing.
One particular mapping update was the `auto_boost` setting on the `all` root
mapper. Being tricky to work on, I removed it in favour of search-time checks
that payloads have been indexed.
One interesting side-effect of the change is that concurrency on ObjectMapper
is greatly simplified since we do not have to care anymore about having
concurrent dynamic mappings and API updates.
Also added a couple nocommits for some issues with tests after mockfs is
working again. But I also re-enabled the mockfs suppression in the base
test case for now.
Allowing tests writing to the working directory can mask problems.
For example, multiple tests running in the same jvm, and using the
same relative path, may cause issues if the first test to run
leaves data in the directory, and the second test does not remember
to cleanup the path before using it.
This change adds security manager rules to disallow tests writing
to the working directory. Instead, tests create a temp dir with
the existing test framework.

This adds a new feature to the Term Vectors API which allows for filtering of
terms based on their tf-idf scores. With `dfs` option on, this could be useful
for finding out a good characteric vector of a document or a set of documents.
The parameters are similar to the ones used in the MLT Query.
Closes#9561
Using ThreadLocalRandom only prevents reproducibilty but doesn't buy us
anything. In production different datapaths won't have the same since
anyway or at least with a low likelyhood.
We need to preserve settings (yet transient) even though the engine is not yet
started. This commit moves back to a single EngineConfig to simplify IndexShard
and settings state.
Closes#10584
Local execution of transport messages failures can create a more detailed remote transport exceptions. Also, when failing to handle an exception, the error should be logged, and not call the handler again with another exception
closes#10554
This commit adds a `rewrite` parameter to the validate API in order to shown
how the given query is re-written into primitive queries. For example, an MLT
query is re-written into a disjunction of the selected terms. Other use cases
include `fuzzy`, `common_terms`, or `match` query especially with a
`cutoff_frequency` parameter. Note that the explanation is only given for a
single randomly chosen shard only, so the output may vary from one shard to
another.

Today the engine writes the transaction log itself as well as manages
all the commit / translog mapping internally. Yet, if an engine is closed
and reopend it doesn't replay it's translog or does anything to be consistent
with it's latest state again.
This change moves the transaction log replay code into the Engine / InternalEngine
and adds unittests for replaying and consistency.
Closes#10452
At the moment, we are very strict when handling data folders containing corrupted shards and will fail any recovery attempt into it. Typically this wouldn't be a problem as the shard will be assigned to another node (which we try first anyway when a shard fails). However, it has been proven to be too strict for smaller clusters which may not have an extra node available (either because of allocation filtering, disk space issues etc.). This commit changes the behavior to force a full recovery. Once all the new files are verified we remove the old corrupted data and start the shard.
This also fixes a small issue where the shard state file wasn't deleted on an engine failure (we had a protection against deleting the state file on an active shard, but in this case the shard is still active but will be removed). The state deletion is also moved to before the failure handlers are called, to avoid race conditions when calling the master (it will potentially try to read it when allocating the shard)
Closes#10558
ShapeBuilder's coordinate parser expected 2 double values for every coordinate array. If > 2 doubles were provided the parser terminated parsing of the coordinate array. This resulted in an invalid Shape state leaving LineStrings, LinearRings, and Polygons with a single coordinate. An incorrect parse exception was thrown. This corrects the parser to ignore those values in the 3rd+ dimension, correctly parsing the rest of the coordinate array.
Unit tests have been updated to verify the fix.
