Date processor was incorrectly parsing week based dates because when a
weekbased year was provided ingest module was thinking year was not
on a date and was trying to applying the logic for dd/MM type of
dates.
Date Processor is also allowing users to specify locale parameter. It
should be taken into account when parsing dates - currently only used
for formatting. If someone specifies 'en-us' locale, then calendar data
rules for that locale should be used.
The exception is iso8601 format. If someone is using that format,
then locale should not override calendar data rules.

This commit adds an optional field, `description`, to all ingest processors
so that users can explain the purpose of the specific processor instance.
Closes#56000.
This commit introduces an optimization for inline scripts.
It keeps the compiled ingest script that the ScriptProcessor.Factory
has been creating for validation purposes. Previously, the Script Service's
cache was leveraged because it was the best way to handle caching of both
stored and inline scripts. Since inline scripts are so widely used in
Ingest Node, it is probably best to ensure we are using the pre-compiled version
from the beginning.
When Joni, the regex engine that powers grok emits a warning it
does so by default to System.err. System.err logs are all bucketed
together in the server log at WARN level. When Joni emits a warning,
it can be extremely verbose, logging a message for each execution
again that pattern. For ingest node that means for every document
that is run that through Grok. Fortunately, Joni provides a call
back hook to push these warnings to a custom location.
This commit implements Joni's callback hook to push the Joni warning
to the Elasticsearch server logger (logger.org.elasticsearch.ingest.common.GrokProcessor)
at debug level. Generally these warning indicate a possible issue with
the regular expression and upon creation of the Grok processor will
do a "test run" of the expression and log the result (if any) at WARN
level. This WARN level log should only occur on pipeline creation which
is a much lower frequency then every document.
Additionally, the documentation is updated with instructions for how
to set the logger to debug level.
* Update DeprecationMap to DynamicMap (#56149)
This renames DeprecationMap to DynamicMap, and changes the deprecation
messages Map to accept a Map of String (keys) to Functions (updated values)
instead. This creates more flexibility in either logging or updating values from
params within a script. This change is required to fix (#52103) in a future PR.
* Fix Source Return Bug in Scripting (#56831)
This change ensures that when a user returns _source directly no matter where
accessed within scripting, the value is a Map of the converted source as
opposed to a SourceLookup.
* Fix empty_value handling in CsvProcessor
Due to bug in `CsvProcessor.Factory` it was impossible to specify `empty_value`.
This change fixes that and adds relevant test.
Closes#55643

This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.
This commit changes how RestHandlers are registered with the
RestController so that a RestHandler no longer needs to register itself
with the RestController. Instead the RestHandler interface has new
methods which when called provide information about the routes
(method and path combinations) that are handled by the handler
including any deprecated and/or replaced combinations.
This change also makes the publication of RestHandlers safe since they
no longer publish a reference to themselves within their constructors.

* Refactor ForEachProcessor to use iteration instead of recursion (#51104)
* Refactor ForEachProcessor to use iteration instead of recursion
This change makes ForEachProcessor iterative and still non-blocking.
In case of non-async processors we use single for loop and no recursion at all.
In case of async processors we continue work on either current thread or thread
started by downstream processor, whichever is slower (usually processor thread).
Everything is synchronised by single atomic variable.

* Update IngestCommonPlugin.java
A very large number of recursive calls can cause a stack overflow
exception. This commit forks the recursive calls for non-async
processors. Once forked, each thread will handle at most 10
recursive calls to help keep the stack size and thread count
down to a reasonable size.

This change adds new ingest processor that breaks line from CSV file into separate fields.
By default it conforms to RFC 4180 but can be tweaked.

JavaDateFormatter should keep the pattern with the prefixed 8 as it will be used for serialisation. The stripped pattern should be used for the enclosed formatters.
closes#48698
There is a watchdog in order to avoid long running (and expensive)
grok expressions. Currently the watchdog is thread based, threads
that run grok expressions are registered and after completion unregister.
If these threads stay registered for too long then the watch dog interrupts
these threads. Joni (the library that powers grok expressions) has a
mechanism that checks whether the current thread is interrupted and
if so abort the pattern matching.
Newer versions have an additional method to abort long running pattern
matching inside joni. Instead of checking the thread's interrupted flag,
joni now also checks a volatile field that can be set via a `Matcher`
instance. This is more efficient method for aborting long running matches.
(joni checks each 30k iterations whether interrupted flag is set vs.
just checking a volatile field)
Recently we upgraded to a recent joni version (#47374), and this PR
is a followup of that PR.
This change should also fix#43673, since it appears when unit tests
are ran the a test runner thread's interrupted flag may already have
been set, due to some thread reuse.
Joda was using ResolverStyle.STRICT when parsing. This means that date will be validated to be a correct year, year-of-month, day-of-month
However, we also want to make it works with Year-Of-Era as Joda used to, hence custom temporalquery.localdate in DateFormatters.from
Within DateFormatters we use the correct uuuu year instead of yyyy year of era
worth noting: if yyyy(without an era) is used in code, the parsing result will be a TemporalAccessor which will fail to be converted into LocalDate. We mostly use DateFormatters.from so this takes care of this. If possible the uuuu format should be used.

This PR changes the ingest executing to be non blocking
by adding an additional method to the Processor interface
that accepts a BiConsumer as handler and changing
IngestService#executeBulkRequest(...) to ingest document
in a non blocking fashion iff a processor executes
in a non blocking fashion.
This is the second PR that merges changes made to server module from
the enrich branch (see #32789) into the master branch.
The plan is to merge changes made to the server module separately from
the pr that will merge enrich into master, so that these changes can
be reviewed in isolation.
This change originates from the enrich branch and was introduced there
in #43361.
This commit adds a helper method to the ingest service allowing it to
inspect a pipeline by id and verify the existence of a processor in the
pipeline. This work exposed a potential bug in that some processors
contain inner processors that are passed in at instantiation. These
processors needed a common way to expose their inner processors, so the
WrappingProcessor was created in order to expose the inner processor.
This commit deprecates all constructors of HandledTransportAction
that take in a Supplier instead of a Writeable.Reader for response
objects.
in addition to the deprecation, the following modules were updated to
leverage Writeable
- modules:ingest-common
- modules:lang-mustache
relates #34389.
This commit moves the Supplier variant of HandledTransportAction to have
a different ordering than the Writeable.Reader variant. The Supplier
version is used for the legacy Streamable, and currently having the
location of the Writeable.Reader vs Supplier in the same place forces
using casts of Writeable.Reader to select the correct super constructor.
This change in ordering allows easier migration to Writeable.Reader.

The base classes for transport requests and responses currently
implement Streamable and Writeable. The writeTo method on these base
classes is implemented with an empty implementation. Not only does this
complicate subclasses to think they need to call super.writeTo, but it
also can lead to not implementing writeTo when it should have been
implemented, or extendiong one of these classes when not necessary,
since there is nothing to actually implement.
This commit removes the empty writeTo from these base classes, and fixes
subclasses to not call super and in some cases implement an empty
writeTo themselves.
relates #34389
Action is a class that encapsulates meta information about an action
that allows it to be called remotely, specifically the action name and
response type. With recent refactoring, the action class can now be
constructed as a static constant, instead of needing to create a
subclass. This makes the old pattern of creating a singleton INSTANCE
both misnamed and lacking a common placement.
This commit renames Action to ActionType, thus allowing the old INSTANCE
naming pattern to be TYPE on the transport action itself. ActionType
also conveys that this class is also not the action itself, although
this change does not rename any concrete classes as those will be
removed organically as they are converted to TYPE constants.
relates #34389
The Action base class currently works for both Streamable and Writeable
response types. This commit intorduces StreamableResponseAction, for
which only the legacy Action implementions which provide newResponse()
will extend. This eliminates the need for overriding newResponse() with
an UnsupportedOperationException.

This processor uses the lucene HTMLStripCharFilter class to remove HTML
entities from a field. This adds to the char filter, so that there is
possibility to store the stripped version as well.
Note, that the characeter filter replaces tags with a newline, so that
the produced HTML will look slightly different than the incoming HTML
with regards to newlines.
* Removed request builder. From 7.0, request builders are no longer used.
* Use RestStatusToXContentListener instead of custom RestBuilderListener in the rest action.
* Changed a few public constructor's and constants' visibility from public to package protected.
(these are only used internally, so no need to for public visibility)
The existing formatter being used was not on par with the joda formatter
as it was missing the ability to parse a comma as a separator between
seconds and milliseconds.
While a real iso8601 would be much more complex, this might be
sufficient for some more use-cases.
The ingest date formatter now also uses the iso8601 formatter by
default.
Closes#38345
If no timezone was specified in the date processor, then the conversion
would lead to wrong time, as UTC was assumed by default, leading to
incorrectly parsed dates.
This commit does not assume a default timezone and will thus not format
the dates in a wrong way.
Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.
This is a continuation of #28667, #36137 and also fixes#37708.
The existing implementation was slow due to exceptions being thrown if
an accessor did not have a time zone. This implementation queries for
having a timezone, local time and local date and also checks for an
instant preventing to throw an exception and thus speeding up the conversion.
This removes the existing method and create a new one named
DateFormatters.from(TemporalAccessor accessor) to resemble the naming of
the java time ones.
Before this change an epoch millis parser using the toZonedDateTime
method took approximately 50x longer.
Relates #37826
The ingest date processor is currently only able to parse joda formats.
However it is not using the existing elasticsearch classes but access
joda directly. This means that our existing BWC layer does not notify
the user about deprecated formats. This commit switches to use the
exising Elasticsearch Joda methods to acquire a date format, that
includes the BWC check and the ability to parse java 8 dates.
The date parsing in ingest has also another extra feature, that the
fallback year, when a date format without a year is used, is the current
year, and not 1970 like usual. This is currently not properly supported
in the DateFormatter class. As this is the only case for this feature
and java time can take care of this using the toZonedDateTime() method,
a workaround just for the joda time parser has been created, that can be
removed soon again from 7.0.
This adds deprecation to _type in the script contexts for ingest and update.
This adds a DeprecationMap that wraps the ctx Map containing _type for these
specific contexts.

* ingest: support simulate with verbose for pipeline processor
This change better supports the use of simulate?verbose with the
pipeline processor. Prior to this change any pipeline processors
executed with simulate?verbose would not show all intermediate
processors for the inner pipelines.
This changes also moves the PipelineProcess and TrackingResultProcessor
classes to enable instance checks and to avoid overly public classes.
As well this updates the error message for when cycles are detected
in pipelines calling other pipelines.
