Previously, an AvailabilityChangeEvent was published when the servlet
and reactive web server application contexts were closed, irrespective
of whether or not the context was active. This caused problems when
the context was not active due to a refresh failure as the event
publication could then trigger bean creation and post-processing that
relied upon beans that had been destroyed when cleaning up after the
refresh failure. The most commonly seen symptom was a missing
importRegistry bean that is required by ImportAwareBeanPostProcessor.
This commit updates the two web server application contexts to only
publish the availability change event if the context is active.
Fixes gh-21588
There's a bug in Undertow that means it may leak a file handle is
the server is stopped immediately after a response to an SSL request
has been received. The stop processing races with Undertow's SSL
support tidying things up after sending the response. When the stop
processing wins, the tidying up fails with a NullPointerException that
prevents an input stream from being closed. On Windows, the input
stream remaining open prevents JUnit from being able to clean up its
temporary directory.
This commit uses Awaitility to wait for the file that's being served
over SSL to be deleted before stopping the server. On Windows, this
will delay the stop processing from beginning until after the tidy up
that's performed after sending the response has been completed,
hopefully eliminating the race condition that resulted in the input
stream being left open.
Fixes gh-21172
Attempt to improve the performance of the `ConfigurationPropertySource`
adapters `containsDescendantOf` method. The method now operates on
arrays rather than iterators and reduces the inner for-loop when
possible.
See gh-21416
Previously, a race between the server starting to reject requests
on a kept-alive connection and the request reaching the blocking
servlet could result in a response never being sent.
This commit updates the test to disable blocking once graceful
shutdown with an in-flight request has being. Awaitility is then used
to make a request on an idle kept-alive connection until it fails
due to the connection reset. This may not happen immediately due to
the aforementioned race.
This commit improves the backward-compatibility of the ErrorAttributes
interfaces by providing a default implementation of a new method. It
also encapsulates several parameters that control the inclusion or
exclusion of error attributes into a new ErrorAttributeOptions type to
make it easier and less intrusive to add additional options in the
future. This encapsulation also makes the handling of the
includeException option more similar to other options.
Fixes gh-21324
Add a `ConfigurationPropertyCaching` utility interface that can be
used to control the property source caching.
Prior to this commit, a `ConfigurationPropertySource` that was backed
by a mutable `EnumerablePropertySource` would need to call the
`getPropertyNames()` method each time a property was accessed. Since
this this operation can be expensive, we now provide a way to cache
the results for a specific length of time.
This commit also improves the performance of immutable property sources
by limiting the number of candidates that need to be searched.
Previously, all mapped names would be enumerated. Now, mappings are
grouped by `ConfigurationPropertyName`. This is especially helpful when
the `ConfigurationPropertyName` isn't mapped at all since the hash based
map lookup will be very fast and the resulting mappings will be empty.
Closes gh-20625
Provide a hashcode implementation for `ConfigurationPropertyName` so
that instances can be stored in Map without them all ending up in the
same bucket.
See gh-20625
Prior to this commit, the property was a Boolean with a null default.
If it was explicitly set by the user, a context customizer would use
that value to set it on the context. However, if it was not set, the default
wouldn't be tomcat's default but `false` because it was explicitly set to
`false` in `TomcatServletWebServerFactory`. This commit defaults the property
itself to `false` so that the default is more obvious to the user.
Fixes gh-20796
Fix the `SystemEnvironmentPropertyMapper.isAncestorOf` implementation
to convert names based on their dashed form and to silently ignore
any invalid results.
Closes gh-14479
Previously, unlike embedded Jetty, Netty, and Tomcat, Undertow would
not stop when one of its worker threads was in use. This meant that a
a long-running or stalled request could prevent the application from
shutting down in response to SIGTERM or SIGINT, and SIGTERM would be
required to get the process to exit.
This commit updates the factories for the reactive and servlet
Undertow web server factories to configure Undertow to use a 0ms
shutdown timeout. This aligns it with the behaviour of Jetty, Netty,
and Tomcat. Tests have been introduced to verify the behaviour across
the reactive and servlet variants of all four supported embedded web
servers.
Fixes gh-21319
Add converter support for `javax.time.Period` including:
String -> Period
Number -> Period
Period -> String
Period to Number conversion is not supported since `Period` has no
ability to deduce the number of calendar days in the period.
See gh-21136
Update the `isAncestorOf` method of SpringConfigurationPropertySources
so that legacy names are considered for the system environment.
Prior to this commit, binding a property such as `my.camelCase.prop`
would detect `MY_CAMELCASE_PROP` but not `MY_CAMEL_CASE_PROP` in
the system environment.
Fixes gh-14479

Update `StaticResourceJars` to catch both `IOException` and
`InvalidPathException` when checking URLs. Prior to this commit only
`IOException` was caught which worked on Java 8 but not Java 11 or
above.
Fixes gh-21312
Update `ValueObjectBinder` reattempt conversion if the `@DefaultValue`
contains a single element. Prior to this commit, single element
conversion relied on the `ArrayToObjectConverter` which isn't always
available.
Fixes gh-21264
Add an `InputStreamSourceToByteArrayConverter` that can be used to
convert from an `InputStreamSource` (such as a `Resource`) to a
byte array.
Closes gh-21285
This commit restricts how wildcards can be used in search
locations for property files. If a search location contains
a pattern, there must be only one '*' and the location should
end with a '*/'. For search locations that specify the file
name, the pattern should end with '*/<filename>'.
The list of files read from wildcard locations are now sorted
alphabetically according to the absolute path of the file.
Closes gh-21217
Prior to this commit, there was a property server.error.include-details
that allowed configuration of the message and errors attributes in a
server error response.
This commit separates the control of the message and errors attributes
into two separate properties named server.error.include-message and
server.error.include-binding-errors. When the message attribute is
excluded from a servlet response, the value is changed from a
hard-coded text value to an empty value.
Fixes gh-20505
This commit adds a new configuration property for configuring the
registration of the default Servlet in Servlet containers.
`"server.servlet.default-servlet.registered=false"`
The default of this property is still `true`, as it's been the case in
previous releases.
Closes gh-21214
This commit upgrades to RSocket 1.0.0-RC7.
This new RC brings API changes we have to adapt to. As of this commit,
we're introducing a new `RSocketServerCustomizer` which replaces the now
deprecated `ServerRSocketFactoryProcessor`.
Closes gh-21046
Previously, DefaultResourceLoader instances were created using the
default constructor. This causes the resource loader to capture the
TCCL that was in place at that time. This can lead to a class loader
leak if the resource loader is referenced directly or indirectly from
a static field of a class loaded by a different class loader.
This commit updates the creation of DefaultResourceLoader instances
in main code so that the resource load will use the class loader of
the creating class. In almost all cases this will be the same class
loader as was the thread context class loader that was being captured
so the change in behavior is minimal. Crucially, it will still address
the situation where the TCCL was different.
Note the DevTools' ApplicationContextResourceLoader has been updated
to explicitly use the TCCL. This ensures that it uses the restart
class loader which is required for DevTools to function correctly.
Fixes gh-20900
Refactor `PortInUseException` logic to a single place and refine when
the exception is thrown.
Prior to this commit, we assumed that a `BindException` was only thrown
when the port was in use. In fact, it's possible that the exception
could be thrown because the requested address "could not be assigned".
We now only throw a `PortInUserException` if the `BindException` message
includes the phrase "in use".
Fixes gh-21101
Update classes that throw `PortInUseException` so that they also
include the cause. Prior to this commit the cause was not included
which could make diagnosing the real cause difficult.
See gh-19807
When using constructor binding, if no properties are bound to
a nested property, the top-level instance will be created with a
null value for the nested property.
This commit introduces support for an empty `@DefaultValue` which
indicates that an instance of the nested property must be created
even if nothing is bound to it. It honors any `@DefaultValue`
annotations that the nested property might have in its constructor.
Closes gh-18917
Update `ConfigFileApplicationListener` so that `spring.profiles.active`
and `spring.profiles.include` can use the square bracket list notation.
Prior to this commit, only comma-separated lists could be used for
those values.
