Guava was removed from Elasticsearch many years ago, but remnants of it
remain due to transitive dependencies. When a dependency pulls guava
into the compile classpath, devs can inadvertently begin using methods
from guava without realizing it. This commit moves guava to a runtime
dependency in the modules that it is needed.
Note that one special case is the html sanitizer in watcher. The third
party dep uses guava in the PolicyFactory class signature. However, only
calling a method on the PolicyFactory actually causes the class to be
loaded, a reference alone does not trigger compilation to look at the
class implementation. There we utilize a MethodHandle for invoking the
relevant method at runtime, where guava will continue to exist.
Now that JDK 14 is available, and we are bundling it, this commit
enables us to run with helpful null pointer exceptions, which will be a
great aid in debugging.
Change how we format exceptions to only wrap them as necessary. While
the config's overall philosophy is to put items one-per-line when
wrapping, in practice this is a little cumbersome for exception lists.
This commit introduces aarch64 packaging, including bundling an aarch64
JDK distribution. We had to make some interesting choices here:
- ML binaries are not compiled for aarch64, so for now we disable ML on
aarch64
- depending on underlying page sizes, we have to disable class data
sharing
When installing plugins from remote sources, either the Elastic download
service, or maven, a checksum file is downloaded and checked against the
downloaded zip. The current format for official plugins is to use a
sha512 checksum which includes the zip filename. This format matches
that from sha512sum, and allows using the --check argument there to
verify the checksum manually. However, when generating checksum files
with maven and gradle, the filename is not included.
This commit relaxes the requirement the filename existing within the
sha512 checksum file for maven plugins. We continue to strictly enforce
official plugins have the existing format of the file.

Back when the distribution launchers were compiled to target JDK 7, we
did not have access to the String#join method to space-delimit JVM
options. Since the launchers now target the same minimum JDK as
Elasticsearch itself, we now have access to this method and can replace
the use of spaceDelimitJvmOptions with String#join. This commit does
that.
This commit prepares the JvmOptionsParser to be more unit testable by
refactoring the class to have some input that it pulls from external
sources passed in as arguments. We do not change any functionality in
this commit, nor add any unit tests, we are only preparing the way.
Now that the FIPS 140 security provider is simply a test dependency
we don't need the thirdPartyAudit exceptions, but plugin-cli and
transport-netty4 do need jarHell disabled as they use the non fips
BouncyCastle security provider as a test dependency too.
This commit introduces the ability to override JVM options by adding
custom JVM options files to a jvm.options.d directory. This simplifies
administration of Elasticsearch by not requiring administrators to keep
the root jvm.options file in sync with changes that we make to the root
jvm.options file. Instead, they are not expected to modify this file but
instead supply their own in jvm.options.d. In Docker installations, this
means they can bind mount this directory in. In future versions of
Elasticsearch, we can consider removing the root jvm.options file
(instead, providing all options there as system JVM options).
This change changes the way to run our test suites in
JVMs configured in FIPS 140 approved mode. It does so by:
- Configuring any given runtime Java in FIPS mode with the bundled
policy and security properties files, setting the system
properties java.security.properties and java.security.policy
with the == operator that overrides the default JVM properties
and policy.
- When runtime java is 11 and higher, using BouncyCastle FIPS
Cryptographic provider and BCJSSE in FIPS mode. These are
used as testRuntime dependencies for unit
tests and internal clusters, and copied (relevant jars)
explicitly to the lib directory for testclusters used in REST tests
- When runtime java is 8, using BouncyCastle FIPS
Cryptographic provider and SunJSSE in FIPS mode.
Running the tests in FIPS 140 approved mode doesn't require an
additional configuration either in CI workers or locally and is
controlled by specifying -Dtests.fips.enabled=true

When installing multiple plugins at once, this commit changes the
behavior to report installed plugins as we go. In the case of failure,
we emit a message that we are rolling back any plugins that were
installed successfully, and also that they were successfully rolled
back. In the case a plugin is not successfully rolled back, we report
this clearly too, alerting the user that there might still be state on
disk they would have to clean up.
This commit allows the plugin installer to install multiple plugins in a
single invocation. The installation will be treated as a transaction, so
that all of the plugins are install successfully, or none of the plugins
are installed.
This fixes a regression introduced in #42042. The logic here was
mistakenly inverted such that we only run these tests in a FIPS JVM
which is the opposite of what we intend.
Backport of #48849. Update `.editorconfig` to make the Java settings the
default for all files, and then apply a 2-space indent to all `*.gradle`
files. Then reformat all the files.
This commit introduces a consistent, and type-safe manner for handling
global build parameters through out our build logic. Primarily this
replaces the existing usages of extra properties with static accessors.
It also introduces and explicit API for initialization and mutation of
any such parameters, as well as better error handling for uninitialized
or eager access of parameter values.
Closes#42042
* Always pass user-specified MaxDirectMemorySize
We had been testing whether a user had passed a value for
MaxDirectMemorySize by parsing the output of "java -XX:PrintFlagsFinal
-version". If MaxDirectMemorySize equals zero, we set it to half of max
heap. The problem is that on Windows with JDK 8, a JDK bug incorrectly
truncates values over 4g and returns multiples of 4g as zero. In order
to always respect the user-defined settings, we need to check our input
to see if an "-XX:MaxDirectMemorySize" value has been passed.
* Always warn for Windows/jdk8 ergo issue
Even if a user has set MaxDirectMemorySize, they aren't future-proof for
this JDK bug. With this change, we issue a general warning for the
windows/JDK8 issue, and a specific warning if MaxDirectMemorySize is
unset.
This commit moves JVM options that we are setting on behalf of the user
that we do not expect them to fiddle with out of the jvm.options
configuration file and into the JVM options parser. In this way, we
discourage fiddling with these settings, but more importantly, we ensure
that as we evolve or add to these settings that a user would pick these
pick instead of being left behind if they have a modified jvm.options
file and do not pick any new that come with the distribution.
Our JVM ergonomics extract max heap size from JDK PrintFlagsFinal output.
On JDK 8, there is a system-dependent bug where memory sizes are cast to
32-bit integers. On affected systems (namely, Windows), when 1/4 of physical
memory is more than the maximum integer value, the output of PrintFlagsFinal
will be inaccurate. In the pathological case, where the max heap size would
be a multiple of 4g, the test will fail.
The practical effect of this bug, beyond test failures, is that we may set
MaxDirectMemorySize to an incorrect value on Windows. This commit adds a
warning about this situation during startup.
This commit removes the option to change the netty system properties to
reenable the direct buffer pooling. It also removes the need for us to
disable the buffer pooling in the system properties file. Instead, we
programmatically craete an allocator that is used by our networking
layer.
This commit does introduce an Elasticsearch property which allows the
user to fallback on the netty default allocator. If they choose this
option, they can configure the default allocator how they wish using the
standard netty properties.
This test has been failing very frequently on Windows checks for 7.4. We've also seen it for 7.x as well as for the new 7.5 tests. I'm muting during investigation so we can see if this is masking any other issues.
Compilation was accidentally broken here when a backport used code from
JDK 9, which is not supported in 7.x. This commit addresses this by
using JDK 8 compatiable APIs.
This commit moves the ES_TMPDIR substitution that we do for JVM options
into the JVM options parser itself. This solves a problem where the fact
that the we do not make the substitution before ergonomics parsing can
lead to the JVM that we start for computing the ergonomic values failing
to start. Additionally, moving this substitution here enables us to
simplify the shell scripts since we do not need to implement this there,
and twice for Bash and Windows.
This is the Java side of https://github.com/elastic/ml-cpp/pull/593
with a fallback so that ml-cpp bundles with either the
new or old directory structure work for the time being.
A few days after merging the C++ changes a followup to
this change will be made that removes the fallback.
We currently configure io.netty.allocator.numDirectArenas to be 0 in the
jvm erconomics class. This is a config that we always want to set, so it
makes sense to move it to jvm.options.
Most of our CLI tools use the Terminal class, which previously did not provide methods for writing to standard output. When all output goes to standard out, there are two basic problems. First, errors and warnings are "swallowed" in pipelines, making it hard for a user to know when something's gone wrong. Second, errors and warnings are intermingled with legitimate output, making it difficult to pass the results of interactive scripts to other tools.
This commit adds a second set of print commands to Terminal for printing to standard error, with errorPrint corresponding to print and errorPrintln corresponding to println. This leaves it to developers to decide which output should go where. It also adjusts existing commands to send errors and warnings to stderr.
Usage is printed to standard output when it's correctly requested (e.g., bin/elasticsearch-keystore --help) but goes to standard error when a command is invoked incorrectly (e.g. bin/elasticsearch-keystore list-with-a-typo | sort).
Elasticsearch does not grant Netty reflection access to get Unsafe. The
only mechanism that currently exists to free direct buffers in a timely
manner is to use Unsafe. This leads to the occasional scenario, under
heavy network load, that direct byte buffers can slowly build up without
being freed.
This commit disables Netty direct buffer pooling and moves to a strategy
of using a single thread-local direct buffer for interfacing with sockets.
This will reduce the memory usage from networking. Elasticsearch
currently derives very little value from direct buffer usage (TLS,
compression, Lucene, Elasticsearch handling, etc all use heap bytes). So
this seems like the correct trade-off until that changes.
This commit applies a normalization process to environment paths, both
in how they are stored internally, also their settings values. This
normalization is done via two means:
- we make the paths absolute
- we remove redundant name elements from the path (what Java calls
"normalization")
This change ensures that when we compare and refer to these paths within
the system, we are using a common ground. For example, prior to the
change if the data path was relative, we would not compare it correctly
to paths from disk usage. This is because the paths in disk usage were
being made absolute.

Today when checksumming a plugin zip during plugin install, we read all
of the bytes of the zip into memory at once. When trying to run the
plugin installer on a small heap (say, 64 MiB), this can lead to the
plugin installer running out of memory when checksumming large
plugins. This commit addresses this by reading the plugin bytes in 8 KiB
chunks, thus using a constant amount of memory independent of the size
of the plugin.
This change makes the process of verifying the signature of
official plugins FIPS 140 compliant by defaulting to use the
BouncyCastle FIPS provider and adding a dependency to bcpg-fips
that implement parts of openPGP in a FIPS compliant manner.
In already FIPS 140 enabled environments that use the
BouncyCastle FIPS provider, the bcfips dependency is redundant
but doesn't cause an issue as it will be added only in the classpath
of the cli-tools
This is a backport of #44224
Java 8 presents the JVM options slightly differently when displaying via
-XX:+PrintFlagsFinal. This commit adapts the JVM options parser for this
possibility.
Relates #42009
This commit removes manual parsing of JVM options when calculating
ergonomics. This is to avoid a situation that we parse values
differently than the JVM would. In fact, we already have a bug along
these lines today. It is possible to start the JVM with the same flag
multiple times on the command line. In this case, the last value
wins. For example, -Xmx1g -Xmx2g would start the JVM with a heap size of
two gigabytes. Our JVM ergonomics ignores this possibility and instead
the first value is winning!
Our strategy to avoid manual parsing of the JVM options is to start the
Java command line parser (without actually starting a JVM) by invoking
java with the same command line flags as presented and request that the
JVM tell us what values it would start with. This ensures that we have
the correct values when making ergonomic decisions.
Moreover, our strategy also is ignoring ES_JAVA_OPTS which could
override the heap size as well leading to incorrect ergonomic
choices. This commit address this issue too.
hamcrest has some improvements in newer versions, like FileMatchers
that make assertions regarding file exists cleaner. This commit upgrades
to the latest version of hamcrest so we can start using new and improved
matchers.
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.
