To reduce configuration time, we fork some threads to compute the Java
version for the various configured Javas. However, as the number of
JAVA${N}_HOME variable increases, the current implementation creates as
many threads as there are such variables, which could be more than the
number of physical cores on the machine. It is not likely that we would
see benefits to trying to execute all of these once beyond the number of
physical cores (maybe simultaneous multi-threading helps though, who
knows. Therefore, this commit limits the parallelization here to the
number number of physical cores.
This commit adds a filter to the files include from modules to only
include platform specific files relevant to the distribution being
built. For example, the deb files on linux would now only include linux
ML binaries, and not windows or macos files.
If no Java versions are set then when we size the executor thread pool
we end up with zero threads, which is illegal. This commit avoids that
problem by only starting the executor when needed.
This commit adds a task rule to print the task dependencies of any task.
It only prints the direct dependencies, but makes debugging missing
dependencies a lot easier.
The SimplifyConditional rule is removing NULL literals from those
functions to simplify their evaluation. This happens in the Optimizer
and a new instance of the conditional function is generated. Previously,
the dataType was not set properly (defaulted to DataType.NULL) for
those new instances and since the resolveType() wasn't called again
it resulted in returning always null.
E.g.:
SELECT COALESCE(null, 'foo', null, 'bar')
COALESCE(null, 'foo', null, 'bar')
-----------------
null
This issue was not visible before because the tests always used an alias
for the conditional function which caused the resolveType() to be
called which sets the dataType properly.
E.g.:
SELECT COALESCE(null, 'foo', null, 'bar') as c
c
-----------------
foo

ClusterFormationTasks auto configured these properties for clusters.
This PR adds FIPS specific configuration across all test clusters from
the main build script to prevent coupling betwwen testclusters and the
build plugin.

Today we assert that there are no operations in flight in this test. However we
will sometimes be in a situation where the operations are blocked, and we
distinguish these cases since #41271 causing the assertion to fail. This commit
addresses this by allowing operations to be blocked sometimes after a primary
promotion.
Fixes#41333.
This will help with reproduction lines and running tests form IDEs and
other operations that are quick and executed often enough for the
configuration time to matter.
Running Gradle with a FIPS JVM is not supproted, so if the runtime JVM
is the same one, no need to spend time checking for fips support.
Verification of the JAVA<version>_HOME env vars is now async and
parallel so it doesn't block configuration.
The `composite` aggregation maps unknown fields as numerics, this means that
any `after` value that is set on a query with an unmapped field on some indices
will fail if the provided value is not numeric. This commit changes the default
value source to use keyword instead in order to be able to parse any type of after
values.
The `_id` field uses a binary encoding to index terms that is not compatible with
the utf8 automaton that the unified highlighter creates to reanalyze the input.
For these reason this commit ignores terms that target the `_id` field when
`require_field_match` is set to false.
Closes#37525
With the removal of the `_all` field the `mlt` query cannot infer a field name
to use to analyze the provided (un)like text if the `fields` parameter is not
explicitly set in the query and the `index.query.default_field` is not changed
in the index settings (by default it is set to `*`). For this reason the like text
is ignored and queries are only built from the provided document ids.
This change fixes this bug by throwing an error if the fields option is not set
and the `index.query.default_field` is equals to `*`. The error is thrown only
if like or unlike texts are provided in the query.
This change clarifies the documentation around the recommended JVM. The
recommended JVM is the bundled JVM. If a user does not use our
recommended JVM we suggest that they use a supported LTS version of the
JVM.
Closes#41132
Fix bug in predicate subtraction that caused the evaluation to be
skipped on the first mismatch instead of evaluating the whole list. In

This fixes an issue where every N seconds a slow search request is triggered
since the searcher access time is not set unless the shard is idle. This change
moves to a more pro-active approach setting the searcher as accessed all the time.
Fix a deprecation warning that wasn't rendering correctly in
asciidoctor. This one needed to be explicitly marked as an inline macro
because it is on its own line and it needed to have its text escaped
because it contained a `,`. It also was missing explanitory text for
what the setting was.
This PR adds additional cleanup when stopping the node.
The data dir is excepted because it gets reused in some tests.
Without this cleanup the number of working dir copies could grew to
exhaust all available disk space.

Today we do not distinguish "no operations in flight" from "operations are
blocked", since both return `0` from `IndexShard#getActiveOperationsCount()`.
We therefore cannot assert that every `TransportReplicationAction` performs its
actions under permit(s). This commit fixes this by returning
`IndexShard#OPERATIONS_BLOCKED` if operations are blocked, allowing these two
cases to be distinguished.
This commit extracts the template management from Watcher into an
abstract class, so that templates and lifecycle policies can be managed
in the same way across multiple plugins. This will be useful for SLM, as
well as potentially ILM and any other plugins which need to manage index
templates.
The date_histogram internally converts obsolete timezones (such as
"Canada/Mountain") into their modern equivalent ("America/Edmonton").
But rollup just stored the TZ as provided by the user.
When checking the TZ for query validation we used a string comparison,
which would fail due to the date_histo's upgrading behavior.
Instead, we should convert both to a TimeZone object and check if their
rules are compatible.
The `ignore_malformed` option currently works on numeric fields only when the
bad value isn't a string value but not if it is a boolean. In this case we get a
parsing error from the xContent parser which we need to catch in addition to the
field mapper.
Closes#11498
Today the `?preference=custom_string_value` search preference will only change
its choice of a shard copy if something changes the `IndexShardRoutingTable`
for that specific shard. Users can use this behaviour to route searches to a
consistent set of shard copies, which means they can reliably hit copies with
hot caches, and use the other copies only for redundancy in case of failure.
However we do not assert this property anywhere, so we might break it in
future.
This commit adds a test that shows that searches are routed consistently even
if other indices are created/rebalanced/deleted.

Today we always trim unsafe commits (whose max_seq_no >= global
checkpoint) before starting a read-write or read-only engine. This is
mandatory for read-write engines because they must start with the safe
commit. This is also fine for read-only engines since most of the cases
we should have exactly one commit after closing an index (trimming is a
noop). However, this is dangerous for following indices which might have
more than one commits when they are being closed.
With this change, we move the trimming logic to the ctor of InternalEngine
so we won't trim anything if we are going to open a read-only engine.
Currently enabling profiling disables top-hits optimizations, which is
unfortunate: it would be nice to be able to notice the difference in method
counts and timings depending on whether total hit counts are requested.
`Node#close` is pretty hard to rely on today:
- it might swallow exceptions
- it waits for 10 seconds for threads to terminate but doesn't signal anything
if threads are still not terminated after 10 seconds
This commit makes `IOException`s propagated and splits `Node#close` into
`Node#close` and `Node#awaitClose` so that the decision what to do if a node
takes too long to close can be done on top of `Node#close`.
It also adds synchronization to lifecycle transitions to make them atomic. I
don't think it is a source of problems today, but it makes things easier to
reason about.
Today we check if an index has broken settings when checking if an index
needs to be upgraded. However, it can be the case that an index setting
became broken even if an index is already upgraded to the current
version if the user removed a plugin (or downgraded from the default
distribution to the non-default distribution) while on the same version
of Elasticsearch. In this case, some registered settings would go
missing and the index would now be broken. Yet, we miss this check and
instead of archiving the settings, the index becomes unassigned due to
the missing settings. This commit addresses this by checking for broken
settings whether or not the index is upgraded.
One of the two #getCorrections methods is only used in tests, so we can move
it and any of the required helper methods to that test. Also reducing the
visibility of several methods to package private since the class isn't used
elsewhere outside the package.
Today we erroneously look for a node setting called `readonly` when deciding
whether or not to create a missing directory in a filesystem repository. This
change fixes this by using the repository setting instead.
Closes#41009

CURRENT_DATE/CURRENT_TIME/CURRENT_TIMESTAMP can be used as SQL keywords
(without parentheses) and therefore there is a special rule in the
grammar to accommodate this.
Previously, this rule was also catching the parenthesised version of those functions too,
not allowing the {fn <functionName>()} to be used. E.g.:
{fn current_time(2)} or {fn current_timestamp()}
Now, the grammar rule catches only the keyword versions and all the parenthesised
versions go through the normal function resolution. As a consequence the validation
of the precision is moved from the parser lever (ExpressionBuilder) to the function
implementations.
