After the bootstrap phase (and with spring.locking.strict=true during the bootstrap phase), getSingletonFactoryBeanForTypeCheck always locks. In a background bootstrap thread, it never locks. Otherwise, it tries locking and explicitly resolves the bean class for subsequent type-based resolution (even for a component-scanned class) when it fails to acquire the lock. Furthermore, getObjectFromFactoryBean follows the same locking algorithm for post-processing.

NonClosingInputStream extends FilterInputStream, which does not forward some
newer InputStream methods such as transferTo and readAllBytes. Specific InputStream
implementations may have more optimized methods (e.g., FileInputStream).

Spring Framework 6.2 introduced support for an escape character for
property placeholders (by default '\'). However, as of Spring Framework
6.2.6, there was no way to either escape the escape character or disable
escape character support.
For example, given a `username` property configured with the value of
`Jane.Smith` and a `DOMAIN\${username}` configuration string, property
placeholder replacement used to result in `DOMAIN\Jane.Smith` prior to
6.2 but now results in `DOMAIN${username}`. Similarly, an attempt to
escape the escape character via `DOMAIN\\${username}` results in
`DOMAIN\${username}`.
In theory, one should be able to disable use of an escape character
altogether, and that is currently possible by invoking
setEscapeCharacter(null) on AbstractPropertyResolver and
PlaceholderConfigurerSupport (the superclass of
PropertySourcesPlaceholderConfigurer).
However, in reality, there are two hurdles.
- As of 6.2.6, an invocation of setEscapeCharacter(null) on a
PropertySourcesPlaceholderConfigurer applied to its internal
top-level PropertySourcesPropertyResolver but not to any nested
PropertySourcesPropertyResolver, which means that the `null` escape
character could not be effectively applied.
- Users may not have an easy way to explicitly set the escape character
to `null` for a PropertyResolver or
PropertySourcesPlaceholderConfigurer. For example, Spring Boot
auto-configures a PropertySourcesPlaceholderConfigurer with the
default escape character enabled.
This first issue above has recently been addressed by gh-34861.
This commit therefore addresses the second issue as follows.
- To allow developers to easily revert to the pre-6.2 behavior without
changes to code or configuration strings, this commit introduces a
`spring.placeholder.escapeCharacter.default` property for use with
SpringProperties which globally sets the default escape character that
is automatically configured in AbstractPropertyResolver and
PlaceholderConfigurerSupport.
- Setting the property to an empty string sets the default escape
character to `null`, effectively disabling the default support for
escape characters.
spring.placeholder.escapeCharacter.default =
- Setting the property to any other character sets the default escape
character to that specific character.
spring.placeholder.escapeCharacter.default = ~
- Setting the property to a string containing more than one character
results in an exception.
- Developers are still able to configure an explicit escape character
in AbstractPropertyResolver and PlaceholderConfigurerSupport if they
choose to do so.
- Third-party components that wish to rely on the same feature can
invoke AbstractPropertyResolver.getDefaultEscapeCharacter() to obtain
the globally configured default escape character.

This commit overrides containsProperty() in
FallbackEnvironmentPropertySource for consistency with the
implementation of ConfigurableEnvironmentPropertySource.
See gh-34861
Although it's unlikely that the implementation of getPropertySources()
in a ConfigurableEnvironment would be overridden to return a different
MutablePropertySources instance than the one that the
ConfigurableEnvironment typically acts on, it is in fact possible.
In light of that possibility, this commit refactors
ConfigurableEnvironmentPropertySource so that it always obtains a fresh
PropertySources reference.
See gh-34861
Commit 3295289e17 fixed a number issues with placeholder resolution in
PropertySourcesPlaceholderConfigurer. However, in doing so, it replaced
a raw PropertySource with a CompositePropertySource which implements
EnumerablePropertySource.
Consequently, all property sources registered in the Environment must
now implement EnumerablePropertySource (which is not an actual
requirement). Otherwise, invocations of getPropertyNames() on the
CompositePropertySource result in an IllegalStateException, and that is
a breaking change which resulted in numerous build failures within the
Spring portfolio.
To address that regression, this commit introduces a private
ConfigurableEnvironmentPropertySource in
PropertySourcesPlaceholderConfigurer which is a "raw" PropertySource
that delegates directly to the PropertySources in a
ConfigurableEnvironment.
This commit also extracts the raw PropertySource for direct Environment
delegation into a new FallbackEnvironmentPropertySource.

Currently, the placeholder resolution algorithm in
PropertySourcesPlaceholderConfigurer fails in several scenarios, and
the root cause for this category of failures has actually existed since
PropertySourcesPlaceholderConfigurer was introduced in Spring Framework
3.1.
Specifically, PropertySourcesPlaceholderConfigurer creates its own
PropertySourcesPropertyResolver that indirectly delegates to another
"nested" PropertySourcesPropertyResolver to interact with
PropertySources from the Environment, which results in double
placeholder parsing and resolution attempts, and that behavior leads to
a whole category of bugs.
For example, #27947 was addressed in Spring Framework 5.3.16, and due
to #34315 and #34326 we have recently realized that additional bugs
exist with placeholder resolution: nested placeholder resolution can
fail when escape characters are used, and it is currently impossible
to disable the escape character support for nested resolution.
To address this category of bugs, we no longer indirectly use or
directly create a "nested" PropertySourcesPropertyResolver in
PropertySourcesPlaceholderConfigurer. Instead, properties from property
sources from the Environment are now accessed directly without
duplicate/nested placeholder resolution.

Prior to this commit, NamedParameterUtils in spring-r2dbc did not
properly expand reused collection parameters. Specifically, values in a
supplied collection were only expanded in the resulting query once, for
the first occurrence of the named parameter.
To address that, this commit effectively reinstates the original logic
for ExpandedQuery from NamedParameterUtils in the Spring Data R2DBC
project.

The last assertion of the new test method currently fails since "foo"
is only bound once.

This commit introduces a new constructor for CompositePropertySource
that accepts a `String name` and an Iterable<PropertySource<?>>, which
allows a CompositePropertySource to be constructed from existing
property sources, such as an instance of MutablePropertySources.

As of gh-33806, the HttpComponents client request factory is forward
compatible with the 5.4+ versions of that library for configuring HTTP
request configuration.
This change would not tkae into account configuration set at the Spring
level because it would consider the default `RequestConfig` instance as
a custom one. This commit ensures that Spring sets its own configuration
if no custom configuration was set for all supported HttpComponents
generations.
Fixes gh-34851
Prior to this commit, bean overrides (such as @MockitoBean, etc.) were
discovered multiple times if they were declared:
- at the type-level on an interface that is implemented at more than
one level in the type hierarchy, the enclosing class hierarchy, or a
combination of the type and enclosing class hierarchies.
or
- on a field declared in a class which can be reached multiple times
while traversing the type and enclosing class hierarchies in
scenarios such as the following: the class (X) in which the field is
declared is a supertype of an enclosing type of the test class, and X
is also an enclosing type of a supertype of the test class.
Such scenarios resulted in an IllegalStateException stating that a
duplicate BeanOverrideHandler was discovered.
To address that, this commit revises the search algorithm in
BeanOverrideHandler so that all types (superclasses, enclosing classes,
and implemented interfaces) are only visited once while traversing the
type and enclosing class hierarchies in search of bean override
handlers.
