* Remove Obsolete BwC Logic from BlobStoreRepository
* We can't restore 1.3.3 files anyway -> no point in doing the dance of computing a hash here
* Some other minor+obvious cleanups
* Dump Stacktrace on Slow IO-Thread Operations
* Follow up to #39729 extending the functionality to actually dump the
stack when the thread is blocked not afterwards
* Logging the stacktrace after the thread became unblocked is only of
limited use because we don't know what happened in the slow callback
from that (only whether we were blocked on a read,write,connect etc.)
* Relates #41745
* Fix testTracerLog Network Tests
* Start appender before using it like we do for e.g. the Netty leak detection appender to avoid interference from actions on the network threads that might still be dangling from previous tests in the same suite
* Closes#41890
* Some Cleanup in o.e.i.engine
* Remove dead code and parameters
* Reduce visibility in some obvious spots
* Add missing `assert`s (not that important here since the methods
themselves will probably be dead-code eliminated) but still
If a single pipeline is updated then the internal representation of
all pipelines was updated. With this change, only the internal representation
of the pipelines that have been modified will be updated.
Prior to this change the IngestMetadata of the previous and current cluster
was used to determine whether the internal representation of pipelines
should be updated. If applying the previous cluster state change failed then
subsequent cluster state changes that have no changes to IngestMetadata
will not attempt to update the internal representation of the pipelines.
This commit, changes how the IngestService updates the internal representation
by keeping track of the underlying configuration and use that to detect
against the new IngestMetadata whether a pipeline configuration has been
changed and if so, then the internal pipeline representation will be updated.
Before this change we would recurse to cache bwc versions.
This proved to be problematic due to the number of steps it was
generating taking too long.
Also this required tricky maintenance to break the recursion for old
branches we don't really care about.
With this change we now cache specific branches only.
We need more information to understand why CcrRetentionLeaseIT is
failing. This commit adds some debug log to retention leases and enables
them in CcrRetentionLeaseIT.
This commit removes the act of renewing some retention leases during a
retention lease recovery test. Having renewal does not add anything
extra to this test, but does allow for some situations where the test
can fail spuriously (i.e., in a way that does not indicate that
production code is broken).
If we close an engine while a refresh is happening, then we might leak
refCount of some SegmentReaders. We need to skip the ram accounting
circuit breaker check until we have a new Lucene snapshot which includes
the fix for LUCENE-8809.
This also adds a test to the engine but left it muted so we won't forget
to reenable this check.
Closes#30290
This change fixes a race condition that would result in an
in-memory data structure becoming out-of-sync with persistent
tasks in cluster state.
If repeated often enough this could result in it being
impossible to open any ML jobs on the affected node, as the
master node would think the node had capacity to open another
job but the chosen node would error during the open sequence
due to its in-memory data structure being full.
The race could be triggered by opening a job and then closing
it a tiny fraction of a second later. It is unlikely a user
of the UI could open and close the job that fast, but a script
or program calling the REST API could.
The nasty thing is, from the externally observable states and
stats everything would appear to be fine - the fast open then
close sequence would appear to leave the job in the closed
state. It's only later that the leftovers in the in-memory
data structure might build up and cause a problem.

The shard CLI tool would not do anything if a corruption marker was not
present. But a corruption marker is only added if a corruption is
detected during indexing/writing, not if a search or other read fails.
Changed the tool to always check shards regardless of corruption marker
presence.

Previously sorting on a missing nested field would fail with an
Exception:
`[nested_field] failed to find nested object under path [nested_path]`
despite `unmapped_type` being set on the query.
Fixes: #33644
(cherry picked from commit 631142d5dd088a10de8dcd939b50a14301173283)
Today the default stabilisation time is calculated on the assumption that the
elected master has no pending tasks to process when it is elected, but this is
not a safe assumption to make. This can result in a cluster reaching the end of
its stabilisation time without having stabilised. Furthermore in #36943 we
increased the probability that each step in `runRandomly()` enqueues another
task, vastly increasing the chance that we hit such a situation.
This change extends the stabilisation process to allow time for all pending
tasks, plus a task that might currently be in flight.
Fixes#41967, in which the master entered the stabilisation phase with over 800
tasks to process.
By default, we track total hits up to 10k but we might index more than
10k documents `testPrimaryRelocationWhileIndexing`. With this change, we
always request for the accurate total hits in the test.
> java.lang.AssertionError: Count is 10000+ hits but 11684 was expected.
Both of these classes are basically a bloated wrapper around a simple
construct that can simply be a DirectoryFactory interface. This change
removes both classes and replaces them with a simple stateless interface
that creates a new `Directory` per shard. The concept of `index.store` is preserved
since it makes sense from a configuration perspective.
This change contains a major refactoring of the timestamp
format determination code used by the ML find file structure
endpoint.
Previously timestamp format determination was done separately
for each piece of text supplied to the timestamp format finder.
This had the drawback that it was not possible to distinguish
dd/MM and MM/dd in the case where both numbers were 12 or less.
In order to do this sensibly it is best to look across all the
available timestamps and see if one of the numbers is greater
than 12 in any of them. This necessitates making the timestamp
format finder an instantiable class that can accumulate evidence
over time.
Another problem with the previous approach was that it was only
possible to override the timestamp format to one of a limited
set of timestamp formats. There was no way out if a file to be
analysed had a timestamp that was sane yet not in the supported
set. This is now changed to allow any timestamp format that can
be parsed by a combination of these Java date/time formats:
yy, yyyy, M, MM, MMM, MMMM, d, dd, EEE, EEEE, H, HH, h, mm, ss,
a, XX, XXX, zzz
Additionally S letter groups (fractional seconds) are supported
providing they occur after ss and separated from the ss by a dot,
comma or colon. Spacing and punctuation is also permitted with
the exception of the question mark, newline and carriage return
characters, together with literal text enclosed in single quotes.
The full list of changes/improvements in this refactor is:
- Make TimestampFormatFinder an instantiable class
- Overrides must be specified in Java date/time format - Joda
format is no longer accepted
- Joda timestamp formats in outputs are now derived from the
determined or overridden Java timestamp formats, not stored
separately
- Functionality for determining the "best" timestamp format in
a set of lines has been moved from TextLogFileStructureFinder
to TimestampFormatFinder, taking advantage of the fact that
TimestampFormatFinder is now an instantiable class with state
- The functionality to quickly rule out some possible Grok
patterns when looking for timestamp formats has been changed
from using simple regular expressions to the much faster
approach of using the Shift-And method of sub-string search,
but using an "alphabet" consisting of just 1 (representing any
digit) and 0 (representing non-digits)
- Timestamp format overrides are now much more flexible
- Timestamp format overrides that do not correspond to a built-in
Grok pattern are mapped to a %{CUSTOM_TIMESTAMP} Grok pattern
whose definition is included within the date processor in the
ingest pipeline
- Grok patterns that correspond to multiple Java date/time
patterns are now handled better - the Grok pattern is accepted
as matching broadly, and the required set of Java date/time
patterns is built up considering all observed samples
- As a result of the more flexible acceptance of Grok patterns,
when looking for the "best" timestamp in a set of lines
timestamps are considered different if they are preceded by
a different sequence of punctuation characters (to prevent
timestamps far into some lines being considered similar to
timestamps near the beginning of other lines)
- Out-of-the-box Grok patterns that are considered now include
%{DATE} and %{DATESTAMP}, which have indeterminate day/month
ordering
- The order of day/month in formats with indeterminate day/month
order is determined by considering all observed samples (plus
the server locale if the observed samples still do not suggest
an ordering)

Today the `TransportClusterStateAction` ignores the state passed by the
`TransportMasterNodeAction` and obtains its state from the cluster applier.
This might be inconsistent, showing a different node as the master or maybe
even having no master.
This change adjusts the action to use the passed-in state directly, and adds
tests showing that the state returned is consistent with our expectations even
if there is a concurrent master failover.
Fixes#38331

Today `RetentionLeaseIT` calls `fail(e.toString())` on some exceptions, losing
the stack trace that came with the exception. This commit adjusts this to
re-throw the exception wrapped in an `AssertionError` so we can see more
details about failures such as #41430.
This commit adds a log message containing the routing table, emitted on each
iteration of the failing assertBusy() in #40174. It also modernizes the code a
bit.
As part of #30241 realm settings were changed to be true affix
settings. In the process of this change, the "ssl." prefix was lost
from the realm truststore password. It should be:
xpack.security.authc.realms.<type>.<name>.ssl.truststore.password
Due to a mismatch between the way we define SSL settings and load SSL
contexts, there was no way to define this legacy password setting in a
realm config.
The settings validation would reject "ssl.truststore.password" but the
SSL service would ignore "truststore.password"
Backport of: #42336
This commit makes creators of GetField split the fields into document fields and metadata fields. It is part of larger refactoring that aims to remove the calls to static methods of MapperService related to metadata fields, as discussed in #24422.
This change moves the construction of the result
HashMap in Grok.captures() into the branch that
actually needs it.
This probably will not make a measurable difference
for ingest pipelines, but it is beneficial to the
ML find_file_structure endpoint, as it tries out
many Grok patterns that will fail to match.
