The logic to extract layers from a downloaded Docker image assumed that
the layer entries in the image tar archive always had the file extension
`.tar`. This was the case with Docker and other compatible daemons until
Docker 25.0. With this commit, the extension is no longer assumed, but
any entries listed in `manifest.json` will be recognized.
Fixes gh-39323
Update `NestedJarFile` so that the `getManifest()` method returns the
manifest from the parent jar file for nested jars based on directory
entries.
This restores the previous behavior supported by Spring Boot 3.1 and
allows class methods such as `getPackage().getImplementationVersion()`
to return non `null` results.
Fixes gh-38996
Update `ZipContent` so that `META-INF` entries are no longer duplicated
in nested jars created from directory entries. This aligns with the
behavior of the classic loader and prevents the same META-INF file from
being discovered twice.
Fixes gh-38862
Update `JarFileArchive` so that unpacked jars use `file:` URLs rather
than `jar:file:`. This aligns with the behavior of Spring Boot 3.1 and
allows calls to `class.getSigners()` to work again.
Fixes gh-38833
1. remove unused imports
2. remove redundant semicolon
3. remove empty class body
4. remove redundant 'constructor' keyword
5. remove redundant 'Unit' return type
6. use non-null type if possible

In gh-38154, we started handling ClosedByInterruptException. The
FileChannel was repaired by recreating it and then the exception was
rethrown. This allowed other threads to use the channel that had been
read by an interrupted thread while allowing that interruption to
continue.
This approach has proven to be insufficient as there are scenarios
where the read needs to succeed on the interrupted thread. This
commit updates the handling of ClosedByInterruptException so that
this is the case. The FileChannel is recreated as before but the
thread's interrupted flag is now cleared before retrying the read.
The flag is then reinstated so that any subsequent actions that
should fail due to the interruption will do so.
We could clear and reinstate the interrupted flag before the first
read, rather than catching ClosedByInterruptException. This approach
was rejected as it will have an impact on the performance of the
happy path where the thread hasn't been interrupted.
Fixes gh-38611
Relax the constraint that a `NestedLocation` must have a nested entry
name specified so that URLs can be split and rebuilt.
Prior to this commit, given a URL of the following form:
jar:nested:/myjar.jar!/nested.jar!/my/file
It was possible to create a FileSystem from
"jar:nested:/myjar.jar!/nested.jar" and from that create a path to
"my/file".
However, it wasn't possible to create a FileSystem from
"jar:nested:/myjar.jar", then create another file system from the path
"nested.jar" and then finally create a path to "/nested.jar".
This was because `nested:/myjar.jar` was not considered a value URL
because it didn't include a nested entry name.
Projects such as `JobRunr` were relying on the ability to compose file
systems, so it makes sense to remove our somewhat artificial
restriction.
Fixes gh-38592
Update `NestedByteChannel.read` so that it loops until all
remaining data has been read into the buffer. Prior to this
commit, it was possible for to read only some bytes into the
buffer. Although it looks like this should be OK according to
the API documentation, the `ZipFileSystem` relies on all
remaining bytes being returned.
Fixes gh-38595
Update `ZipContent` so that `eocd.totalNumberOfCentralDirectoryEntries`
is converted from a short to an unsigned int to prevent a negative
number from being used.
This commit also updates the code to consistently use `X.toUnsigned...`
helper methods rather than using bitwise operators.
Fixed gh-38572
Update jar `Handler` code so that the `parseUrl` method can accept an
empty `spec`. Prior to this commit, a `classLoader.getResource("")`
call would result in a `null` result. This breaks a number of things
including `ClassPathResource` and `PathMatchingResourcePatternResolver`.
Fixes gh-38524
Update `JarUrlConnection` and `NestedUrlConnection` so that calls
to `getLastModified()` and `getHeaderFieldDate("last-modified", 0)`
always return a result.
Fixes gh-38204
When an interrupted that calls FileChannel.read, the channel is
closed and the read fails with a ClosedByInterruptException. The
closure of the channel makes it unusable by other threads. To
allow other threads to read from the data block, this commit
recreates the FileChannel when a read fails on an interrupted
thread with a ClosedByInterruptException. The exception is then
rethrown to continue the thread's interruption.
Closes gh-38154
Previously, the .class file for the renamed properties class was
on the class path of the compilation in two places:
1. The output directory of the test's previous compilation
2. The output directory of the compilation of src/test/java of
spring-boot-configuration-processor
The first of these locations is addressed by updating TestProject.
The .class file is now deleted from the project's output location
at the same time as the .java file is deleted from its source
location.
The second of these locations is addressed by configuring the class
path of the compiler to include a copy of the result of compiling
src/test/java of spring-boot-configuration-processor. From this copy
entries can then be deleted as needed without destabilizing other tests.
Closes gh-26271
