This commit creates a separate
`ServerPropertiesServletContainerCustomizer` that holds the servlet
container customization code, separating that concern from the server
configuration keys.
See gh-8066
This commit refactors the `ServerProperties` property keys and
introduces a separate "server.servlet" namespace to isolate
servlet-specific properties from the rest.
Closes gh-8066
This contract is not specific to servlet containers and should be
reused by all web server implementations (including reactive variants).
Fixes gh-8208
This commit removes `ServerProperties` and `ManagementServerProperties`
auto-configurations. Those properties objects are now created using
`@EnableConfigurationProperties` only.
Closes gh-8108
This commit raises the minimum supported version of Thymeleaf to
3.0.x. It also upgrades Spring Social to a version that is compatible
with Thymeleaf 3.

Previously, when DevTools' was used it would set the application
context's ResourceLoader and overwrite any custom ResourceLoader that
had been configured. On the rare occasion when the user had customized
the ResourceLoader this meant that the customization was lost and
certain resources would become unavailable.
This commit updates DevTools' ResourceLoader to delegate a custom
ResourceLoader if one has been configured. If one has not been
configured it delegates as before, i.e. to
WebApplicationContextResourceLoader for web applications and to
DefaultResourceLoader for all others apps.
Closes gh-8010
The intent of the test is to:
1. Make a change
2. Sleep for long enough for that change to be picked up
3. Make another change
4. Stop that watcher after 1 further scan has been performed
5. Assert that a further scan was performed by checking that two
separate sets of changes (step 1 and step 3) have been picked up
Previously, step 2 relied on simply sleeping for a period of time
longer than the polling interval. In reality, the polling interval
is only a minimum time between scans and the actual time between them
depends on thread scheduling, GC pauses, etc. This lead to the
test failing intermittently if the scan didn't happen in a timely
manner.
This commit removes the sleep and replaces it with a while loop that
waits for first change to be picked up. This ensures that the second
change will be detected separately from the first and that two
separate change sets should always be available once the watcher has
stopped.

Update ClassLoaderFilesResourcePatternResolver to support servlet
resources when it's being used with a WebApplicationContext.
Prior to commit 918e122ddc a `ResourceLoader` was not added to the
`ApplicationContext`, meaning that servlet resources could be found by
virtue of the protected `getResourceByPath()` method. Following commit
918e122ddc, the context `ResourceLoader` is set, meaning that all calls
to `getResource` delegate to the `ResourceLoader` and the
`ApplicationContext` methods are not invoked. Since the devtools
`ResourceLoader` wasn't Servlet aware, servlet resources could not
be found.
Fixes gh-7752
We use some internal Mockito classes and some breaking API changes
have been made to them in Mockito 2. This commit introduces a utility
class, SpringBootMockUtil, to shield our code from these differences.
Mockito 1 is called directly and Mockito 2 is called via reflection.
To allow these changes to be tested, FilteredClassPathRunner has been
enhanced to also support overriding a dependency on the class path.
As a result it has been renamed to ModifiedClassPathRunner. The new
ClassPathOverrides annotation can be used to provide the Maven
coordinates of one or more dependencies that should be resolved and
added to the class path. Such additions are added to the start of
the class path so that they override any existing dependency that
contains the same classes.
Closes gh-6520
Update `DevToolsPropertyDefaultsPostProcessor` so that property defaults
are only added at development time. Properties are now added only when
`Restarter` is initialize or remote devtools is enabled.
Fixes gh-7014
This commit switches off the auto-configured JspServlet's
development mode by default. Development mode is then switched on
when DevTools is on the class path.
Closes gh-7039
Prior to this commit any application configured to write
`META-INF/build-info.properties` could trigger unexpected application
restarts. The problem is particularly prevalent when using Eclipse M2E in
combination with Maven's `spring-boot-maven-plugin` `build-info` goal
and Gradle's `springBoot` `buildInfo()`.
Closes gh-7002
DevTools deliberately throws an uncaught exception on the main thread
as a safe way of causing it to stop processing. This exception is
caught and swallowed by an uncaught exception handler. Unfortunately,
this has the unwanted side-effect of causing the JVM to exit with 1
once all running threads are daemons.
Normally, this isn't a problem. Non-daemon threads, such as those
started by an embedded servlet container, will keep the JVM alive and
restarts of the application context will occur when the user makes to
their application. However, if the user adds DevTools to an
application that doesn't start any non-daemon threads, i.e. it starts,
runs, and then exits, it will exit with 1. This causes both
bootRun in Gradle and spring-boot:run in Maven to report that the
build has failed. While there's no benefit to using DevTools with an
application that behaves in this way, the side-effect of causing the
JVM to exit with 1 is unwanted.
This commit address the problem by updating the uncaught exception
handler to call System.exit(0) if the JVM is going to exit as a
result of the uncaught exception causing the main thread to die. In
other words, if the main thread was the only non-daemon thread, its
death as a result of the uncaught exception will now cause the JVM
to exit with 1 rather than 0. If there are other non-daemon threads
that will keep the JVM alive, the behaviour is unchanged.
Closes gh-5968
Previously, Spring Data Redis assumed that the class loader that loaded
its classes would also be able to load the application’s classes. This
assumption is faulty when there are multiple class loaders involved
such as when using dev tools or when Spring Data Redis is installed as
a shared library in a servlet container.
DATAREDIS-427 and DATAREDIS-501 removed this assumption by making the
default serialiser use the bean class loader. DevTools configures this
class loader to be the restart class loader which can load the
application’s classes. As a result of moving to Hopper SR2 snapshots,
these fixes are now available and we can remove our custom serialised.
Closes gh-5760
The list of changes is written to on one thread and read from on
another. Without some form of sychronization this is not thread-safe.
This commit makes changes a synchronized list which should guarantee
that the reading thread can see the changes made by the writing thread.
It also removes a redundant call to clear the list of changes at the
start of waitsForPollingInterval.
See gh-6038
Previously, there were two problems with DevTools’ DataSource
auto-configuration:
1. It did not tolerate a context with multiple DataSources
2. It would attempt to shut down a DataSource that had not been created
by DataSourceAutoConfiguration and, therefore, where we could not be
sure of its configuration.
This commit updates DevToolsDataSourceAutoConfiguration so that it backs
off unless the context contains DataSourceProperties and a single
DataSource created by DataSourceAutoConfiguration. This ensures that it
can safely use DataSourceProperties to get the DataSource’s
driver class name and accurately determine if it’s an in-memory or
external database. Shutdown is only called for an in-memory database.
Closes gh-5540
5e0ba6ea added support for reading a jar manifest's Class-Path
attribute when resolving changeable URLs from a URLClassLoader,
however it did not handle relative URLs, i.e. URLs without a protocol,
correctly.
This commit updates ChangeableUrls so that it uses the URL of the
JAR that contains the manifest as the base for any new URLs that
are created. When the Class-Path entry is relative, this base will
be used. When the Class-Path entry is absolutee, URL's constructor
will ignore the supplied base.
Closes gh-5665
To overcome command length limits on Windows, IntelliJ IDEA may launch
an application with a single jar on the classpath that contains that
application's actual classpath in the Class-Path attribute of its
manifest. This would prevent DevTools restarts from working as it
only considered the single jar's URL when identifying changeable URLs
and ignored the URLs added to the classpath via the jar's manifest.
This commit updates ChangeableUrls when it is created from a
URLClassLoader to consider the Class-Path manifest attribute of any
jars in the class loader's URLs. This allows the full classpath to
be considered when identifying URLs that are changeable and that
need to be monitored for restart triggering.
