This commit introduces support for R2DBC ("Reactive Relational Database
Connectivity") with custom ConnectionFactory implementations, a
functional DatabaseClient for SQL execution, transaction management, a
bind marker abstraction database initialization utilities, and
exception translation.
Closes gh-25065
This commit introduces a change in reactive transaction semantics for
cancel signals. Canceling a subscription now rolls back a reactive transaction
to achieve a deterministic transaction outcome.
Previously, cancel signals committed a transaction which could
cause partially committed transactions depending on when the cancel happened.
Prior to this commit (and the previous one), the `AntPathStringMatcher`
(inner class of `AntPathmatcher`) would compile `Pattern` instances and
use regex matching even for static patterns such as `"/home"`.
This change introduces a shortcut in the string matcher algorithm to
skip the `Pattern` creation and uses `String` equality instead.
Static patterns are quite common in applications and this change can
bring performance improvements, depending on the mix of patterns
configured in the web application.
In benchmarks (added with this commit), we're seeing +20% throughput
and -40% allocation. This of course can vary depending on the number of
static patterns configured in the application.
Closes gh-24887
Prior to this commit, the Spring Framework test suite would rely only on
"Performance" tests associated with a specific CI build. As outlined in
gh-24830, the way they're built and executed is not working well
anymore.
This commit introduces a new JMH benchmark infrastructure in the build.
The goal here is not to run those benchmarks as part of a CI build, but
rather provide a proper infrastructure for writing and locally running
micro-benchmarks when working on specific optimizations.
This commit adds and configures a Gradle JMH plugin to allow for JMH
benchmark classes in Spring Framework modules (in `src/jmh/java` of each
`spring-*` module). It's also relaxing the checkstyle rules for JMH
classes, especially around Javadoc rules: this code is not meant to
have Javadocs.
Finally, this commit links to a new Wiki page on the project GitHub
repository documenting the infrastructure and helping contributors to
run and design benchmarks.
See gh-24830
TransactionAttribute now exposes a labels attribute that associates a
descriptive array of labels with a transaction.
Labels may be of a pure descriptive nature or may get evaluated by
transaction managers to associate technology-specific behavior
with the actual transaction.
This commit introduces support for setting the
spring.test.constructor.autowire.mode property via a JUnit Platform
configuration parameter -- for example, via the
junit-platform.properties file.
Closes gh-24285
Since the spring-framework.png file is not used in the generated
reference manual, this commit moves the spring-framework.png file from
the src/docs/asciidoc/images folder up to the src/docs folder.
As of gh-24952, `PathPatternParser` will strictly reject patterns with
`"**"` in the middle of them. `"**"` is only allowed at the end of the
pattern for matching multiple path segments until the end of the path.
Currently, if `"**"` is used in the middle of a pattern it will be
considered as a single `"*"` instead. Rejecting such cases should
clarify the situation.
This commit prepares for that upcoming change and:
* logs a warning message if such a case is used by an application
* expands the MVC and WebFlux documentation about URI matching in
general
Closes gh-24958
Prior to this commit, it was unclear in the documentation that a default
constructor will be used by default for autowiring if multiple
constructors are present and none of them is annotated with @Autowired.
This commit improves the documentation in this regard.
Closes gh-24838
