Prior to this commit and the previous commit, SimpleJdbcInsert did not
provide built-in support for "quoted identifiers". Consequently, if any
column names conflicted with keywords or functions from the underlying
database, you had to manually quote the column names when specifying
them via `usingColumns(...)`, and there was unfortunately no way to
quote schema and table names.
The previous commit provided rudimentary support for quoted SQL
identifiers (schema, table, and column names) by querying
java.sql.DatabaseMetaData.getIdentifierQuoteString() to determine the
quote string. It also introduced `usingEscaping(boolean)` in
`SimpleJdbcInsertOperations` to enable the feature. However, it
incorrectly quoted the schema and table names together, and it did not
take into account the fact that a quoted identifier should respect the
casing (uppercase vs. lowercase) of the underlying database's metadata.
This commit revises quoted identifier support in `SimpleJdbcInsert` by:
- renaming `usingEscaping(boolean)` to `usingQuotedIdentifiers()`
- quoting schema and table names separately
- respecting the casing (uppercase vs. lowercase) of the underlying
database's metadata when quoting identifiers
- introducing integration tests against an in-memory H2 database

This commit improves how the build deals with javadoc invalid references
in two ways.
Link/see references that are temporarily invalid during javadoc
generation of individual modules are better masked by using the option
`Xdoclint:syntax` instead of `Xdoclint:none` (warnings were still
visible in some cases, e.g. when individually building the javadoc for
a specific module).
Global javadoc-building task `api` now combines `syntax` and `reference`
`Xdoclint` groups, allowing to raise truly invalid references even when
all the modules have been aggregated.
This commit also fixes the 20+ errors which appeared following the later
change in doclet configuration.
Closes gh-30428
This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit adds mapping for two types from the `java.time` package,
complementing the types that are already translatable to Sql types
TIME, DATE and TIMESTAMP:
- `OffsetTime` maps to a `TIME_WITH_TIMEZONE`
- `OffsetDateTime` maps to a `TIMESTAMP_WITH_TIMEZONE`
This is in accordance with the B.4 table provided in the JDBC 4.2
specification.
When preparing statements, these `java.time` types use the `setObject`
method. Tests covering the 5 `java.time` classes have also been added.

This commit picks up where the two previous commits left off.
Specifically, this commit:
- Removes the "severity=warning" configuration to ensure that violations
actually fail the build.
- Fixes regular expressions for suppressions by matching forward
slashes using `[\\/]` instead of `\/`.
- Moves the configuration for newly introduced checks to locations in
checkstyle.xml that align with the existing organization of that file.
- Renames the IDs for RegexpSinglelineJava checks from
javaDocPackageNonNullApiAnnotation/javaDocPackageNonNullFieldsAnnotation
to packageLevelNonNullApiAnnotation/packageLevelNonNullFieldsAnnotation,
respectively, since these checks are not related to Javadoc.
- Simplifies the null-safety annotation checks to match against
imported annotation types, which enforces consistency across
package-info.java files for the annotation declarations.
- Simplifies the RegEx for JavadocPackage suppressions to only exclude
packages not under src/main/java (vs src/main) and those in the
framework-docs module.
- Consistently suppresses all checks for the `asm`, `cglib`, `objenesis`,
and `javapoet` packages in spring-core.
- Adds explicit suppressions for null-safety annotations for the `lang`
package in spring-core.
- Adds explicit suppressions for null-safety annotations for the
`org.aopalliance` package in spring-aop.
- Revises the RegEx for null-safety annotation suppressions to only
exclude package-info.java files not under src/main/java and
additionally to exclude package-info.java files in the framework-docs
module as well as those in the spring-context-indexer,
spring-instrument, and spring-jcl modules.
- Adds all missing package-info.java files.
- Adds null-safety annotations to package-info.java files where
appropriate.

Prior to this commit, the term "field" was sometimes used to refer to a
database column and sometimes used to refer to a bean property, which
lead to confusion in the Javadoc as well as within the code.
This commit addresses this by avoiding use of the term "field".
This commit introduces SqlServerSequenceMaxValueIncrementer to support
SQL Server sequences, complementing the existing
SqlServerMaxValueIncrementer for table-based support.

This commit also removes ResourcePropertiesPersister which
was introduced in 5.3 specifically for spring.xml.ignore
flag and which is expected to be used only internally by
Spring Framework. DefaultPropertiesPersister should be used
instead.

As of Java 18, the serial lint warning in javac has been expanded to
check for class fields that are not marked as `Serializable`.
See https://www.oracle.com/java/technologies/javase/18all-relnotes.html#JDK-8202056
In the Spring Framework codebase, this can happen with `Map`, `Set` or
`List` attributes which are often assigned with an unmodifiable
implementation variant. Such implementations are `Serializable` but
cannot be used as field types.
This commit ensures that the following changes are applied:
* fields are marked as transient if they can't be serialized
* classes are marked as `Serializable` if this was missing
* `@SuppressWarnings("serial")` is applied where relevant
These tests often fail on the CI server and do not provide any
meaningful information when they fail, since only a proper benchmark
would suffice. Furthermore, the test method was introduced 10 years
ago to address deficiencies in JDK 7 which no longer exist.

Prior to this commit, the `ConcurrentLruCache` implementation would not
perform well under certain conditions. As long as the cache capacity was
not reached, the cache would avoid maintaining an eviction queue
(reordering entries depending with least/most recently read). When the
cache capacity was reached, the LRU queue was updated for each
read/write operation. This decreased performance significantly under
contention when the capacity was reached.
This commit completely rewrites the internals of `ConcurrentLruCache`.
`ConcurrentLruCache` is now a specialized version of the
`ConcurrentLinkedHashMap` [1]. This change focuses on buferring read and
write operations, only processing them at certain times to avoid
contention.
When a cached entry is read, a read operation is queued and buffered
operations are drained if the buffer reached a fixed limit. When a new
cache entry is added or removed, a write operation is queued and
triggers a drain attempt. When the capacity is outgrown, the cache polls
items from the eviction queue, which maintains elements with the
least recently used ones first. Entries are removed until the capacity
is under control.
The behavior described here and the buffer sizes are optimized with the
number of available processors in mind. Work is localized as much as
possible on a per-thread basis to avoid contention on the eviction queue.
The new implementation has been tested with the JMH benchmark provided
here, comparing the former `COncurrentLruCache`, the new implementation
as well as the `ConcurrentLinkedHashMap` [1].
When testing with a cache reaching capacity, under contention, with a
10% cache miss, we're seeing a 40x improvement compared to the previous
implementation and performance on par with the reference.
See [2] for how to replicate the benchmark.
