To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.

Many of the utility methods in ScriptUtils are public only because they
were once invoked from JdbdTestUtils in spring-test, which is no longer
the case. Consequently, there should no longer be a need for any
external clients to invoke such methods.
To address this, this commit formally deprecates the following methods
in ScriptUtils in spring-jdbc.
- readScript(...)
- containsSqlScriptDelimiters(...)
- splitSqlScript(...)
Closes gh-26947
Prior to this commit, the implementations of
ScriptUtils.containsSqlScriptDelimiters() in spring-jdbc and
spring-r2dbc did not ignore comments when searching for the statement
delimiter within an SQL script. This resulted in subtle bugs if a
comment contained a single single-quote or single double-quote, since
the absence of the closing single-quote or double-quote led the
algorithm to believe that it was still "within a text literal". Similar
issues could arise if a comment contained the sought statement
delimiter but the rest of the script did not contain the sought
statement delimiter. In such cases, the algorithms in ScriptUtils could
erroneously choose an incorrect statement delimiter -- for example,
using the fallback statement delimiter instead of the delimiter
specified by the user.
This commit avoids such bugs by ignoring single-line comments and block
comments when searching for the statement delimiter within an SQL
script.
Closes gh-26911
Prior to this commit, the containsSqlScriptDelimiters() method in
ScriptUtils ignored delimiters enclosed in single quotes but not those
enclosed within double quotes, which contradicts the algorithm in
splitSqlScript() and therefore constitutes a bug.
This commit fixes this bug in the ScriptUtils implementations in
spring-jdbc and spring-r2dbc.

Prior to this commit, MySQLMaxValueIncrementer could not be used when
the MySQL database was configured to use safe-updates mode.
See https://dev.mysql.com/doc/refman/8.0/en/mysql-tips.html#safe-updates
This commit introduces a `limit 1` clause to the generated update
statement to allow MySQLMaxValueIncrementer to be compatible with
MySQL safe-updates mode.
Closes gh-26858
Prior to this commit, if an SQLException was thrown while retrieving
column metadata from the database, SimpleJdbcInsert would generate an
INSERT statement that was syntactically valid but missing columns,
which could lead to data silently missing in the database (for nullable
columns).
This commit fixes this by clearing all collected column metadata if an
SQLException is thrown while processing the metadata. The result is
that an InvalidDataAccessApiUsageException will be thrown later while
generating the INSERT statement. The exception message now contains an
additional hint to make use of SimpleJdbcInsert#usingColumns() in order
to ensure that all required columns are included in the generated
INSERT statement.
SimpleJdbcCall can also encounter an SQLException while retrieving
column metadata for a stored procedure/function, but an exception is
not thrown since a later invocation of the stored procedure/function
will likely fail anyway due to missing arguments. Consequently, this
commit only improves the warning level log message by including a hint
to make use of SimpleJdbcCall#addDeclaredParameter().
Closes gh-26486
This commit reverts some changes done in 2d5f9723fa
in order to fix JdbcOperations.queryForObject and
JdbcOperations.queryForList.
It is not possible to provide a vararg variant in Kotlin
for now due to a signature clash, but that will probably
make sense in Spring Framework 6 timeframe along to array
based variant removal for both Java and Kotlin.
Closes gh-26312
Prior to this commit, some tests would belong to the PERFORMANCE
`TestGroup`, while they were not testing for performance but rather
performing functional tests that involve long running operations or
timeouts.
This commit moves those tests to the LONG_RUNNING `TestGroup`.
See gh-24830
Includes deprecation of JdbcUtils.extractDatabaseMetaData(DataSource, String) in favor of the now generified version of extractDatabaseMetaData(DataSource, DatabaseMetaDataCallback).

MVC data class processor constructs target instance even in case of binding failure, as long as the corresponding method parameter is not marked as optional.

- The compiler is configured to retain compatibility with Kotlin 1.3.
- Explicit API mode is not yet enabled but could be in the future.
- Some exceptions thrown by Kotlin have changed to NullPointerException,
