Exiting with 0 when cd fails is likely to be incorrectly interpreted
as success so we should exit with a non-zero value. Ideally, the init
script status action would exit with 4 but, at the point when
the cd is performed, we don’t even know if we’re running as an init
script. Exiting with 1 seems to be a reasonable compromise as it’s
fine for the non init-script case as well as being correct for all
init script actions other than status.

Allow users to easily opt-opt of using the start-stop-daemon in the
launch script. This may be required on distros that include older
versions.
Fixes gh-4732
There’s a race condition in start-stop-daemon when --make-pidfile and
--background are used together [1]. This race condition can lead to the
command returning before the PID file has been created. The missing PID
file then causes the launch script to incorrectly report that the
service failed to start.
This commit updates the launch script to wait for up to 10 seconds for
the PID file to be created when start-stop-daemon is used to launch the
app.
Closes gh-4524

Update the launch script so that the PID file is not longer removed at
the beginning of the stop method. Prior to this commit if a service
wasn't able to stop on the first run, it wasn't possible to use the
launch script anymore.
Fixes gh-4369
Closes gh-4371
The HUP signal was being used to stop the service and for some reason,
sometimes it was being ignored. This commit change forces the use of the
TERM signal (the default signal of kill).
Fixes gh-4378
Closes gh-4414
By default, start-stop-daemon will chdir to the root directory before
starting the process. This prevents an application.properties file that
sits alongside the jar from being found.
This commit updates the call to start-stop-daemon to use --chdir to
set the working directory to that of the jar that’s being launched.
Closes gh-4281
Update the "INIT INFO section" of `launch.script` to include
`initInfoProvides`, `initInfoShortDescription` and `initInfoDescription`
property substitutions.
The Maven plugin has been updated to populate substitutions with
`${project.artifactId}`, `${project.name}` and `${project.description}`.
Fixes gh-4245
The init script spec [1] describes a number of requirements with which
our launch.script did not comply. This commit makes the following
corrections:
- Add support for force-reload which should be implemented by all
init scripts
- Don't fail restart if the service is already stopped or not running
- Consider stop to be successful if the service is already stopped
- Exit with 1 if stop fails (indicating a generic or unspecified error)
rather than 3 (unimplemented feature)
- Report a status of 1 if app is not running but the pid file exists
- Report a status of 3 if the app is not running (no pid file)

Previously, the launch script would always use a file named
<appname>.log to capture the application's console output. This commit
adds a variable, LOG_FILENAME, for specifying the file name defaulting
to <appname>.log.
Fixes gh-4194
Update `launch.script` to use `start-stop-daemon` when possible to
manage daemon processes. When `start-stop-daemon` is not available `su`
is used.
Closes gh-4137
The recommended usage for the java executable is:
java [-options] -jar jarfile [args...]
This commit updates the default launch script to match this recommended
usage by moving -jar to be the last option, after both the
disableJarChecking system property and any JAVA_OPTS.
Closes gh-3930
Use "return" instead of "exit" where possible, especially in
function definitions.
Also fixed the exit codes to match the LSB spec for some specific
conditions (fixes gh-3521).
Fixes gh-3199, fixes gh-3535
When writing a jar, once an entry has been written it will never be
overwritten, i.e. the first write of a given entry will win. Previously,
when repackaging a jar, the existing contents were written followed by
any libraries. This caused a problem when repackaged a WAR file and
a library needed to be unpacked as the existing entry in WEB-INF/lib
would prevent the library with the UNPACK comment from being written.
This was addressed in f761916b by inverting the order so libraries
would take precedence over entries in the source jar.
It’s now become apparent that this change in the order causes a problem
for users who are obfuscating their code. The obfuscated code exists in
the source jar but is also provided to the repackager in its original
form as a library. When libraries take precedence, this means that the
code in its original form ends up in the repackaged war and the
obfuscation is lost.
This commit updates the repackager to write libraries that require
unpacking first. This allows the UNPACK comment to be written even if
there’s also a source entry for the library. Next, source entries are
written. This allows obfuscated source entries to take precedence over
any unobfuscated library equivalents. Lastly, standard libraries that
do not require unpacking are written into the repackaged archive.
Closes gh-3444
Update the embedded launch script to include a `chkconfig` comment. This
solves the "Service doesn't support chkconfig" error when executing
the chkconfig command.
Fixes gh-3115
Update the launch script used in fully executable jars to:
- Include LSB-Header comments
- Source `.conf` files either next to the jar for additional script
configuration

SpringApplicationLifecycle provides basic lifecycle operations on the
current Spring Boot application (that is checking if the application has
fully started and gracefully terminate the app). It can be registered as
an MBean of the platform MBean server if a specific property is set.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.
Such change permits the maven plugin to integrate a classical integration
test scenario where the "start" goal is invoked during the
pre-integration phase and the "stop" goal during the post-integration
phase.
Closes gh-2525
Some of the features of the launch.script were not exposed for users
to be able to control at runtime. It now accepts things like
PID_FOLDER and LOG_FOLDER as environment variables, and also adopts
a clear naming convention where only the inputs are UPPER_CASE.
Update JarWriter to set the entry timestamp for nested jars. The
timestamp is set to same time as the first (non directory) entry in
the nested jar.
This change should make it easier to created layered docker images.

SpringApplicationLifecycle provides lifecycle operations on the current
Spring Boot application. It can be registered as an MBean of the platform
MBean server if a specific property is set. Besides, the JMX name can
also be customized via a property in case more than one Spring Boot
application is started in the same process.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.

Update the Maven and Gradle plugin to generate fully executable jar
files on Unix like machines. A launcher bash script is added to the
front of the jar file which handles execution.
The default execution script will either launch the application or
handle init.d service operations (start/stop/restart) depending on if
the application is executed directly, or via a symlink to init.d.
See gh-1117
Previously repackaging of an archive was performed in three steps:
1. Write the manifest
2. Write entries from the source archive into the destination
3. Write any libraries into the destination if they’re not already there
This worked fine for jar files, but not for war files. In the war file
case the libraries are already in the source archive’s WEB-INF/lib
directory so they’re copied into the destination in step 2. This means
that step 3 largely becomes a no-op and, crucially, the UNPACK comment
is not applied to any libraries that require it.
This commit reorders steps 2 and 3 so that the libraries are copied into
the destination first (allowing the UNPACK comment to be written, if
required) and then any entries in the source are written into the
destination if they’re not already there.
Fixes gh-2588
Add a 'module' layout for the repackager which includes all 'compile'
and 'runtime' scope dependencies and does not require a main class.
Fixes gh-1941
Prior to this commit, the repackage goal silently ignored the case of
two libraries having the same name and version but a different group.
As a result, the second library was overwriting the first one in the
repackaged jar.
This commit adds support for custom Library names and updates the
Maven and Gradle plugins so that the name includes the group ID
when there would otherwise be a duplicate.
Fixes gh-1475
Previously, Repackager would repackage a jar file as many times as
it was asked to do so. This lead to problems if a user made a mistake
when using Maven that led to the package phase being driven twice,
for example by running "mvn clean install package".
This commit updates Repackager so that a repackage call becomes a
no-op if the source jar's manifest already contains the
Spring-Boot-Version attribute which is added by repackaging.
Fixes#1251
Before this change a property whose key was in a non-enumerable property source would
not resolve placeholders, leading to ${style} values in @ConfigurationProperties beans
even if the placeholders ere resolvable.
Update the executable JAR code to automatically unpack any entries
which include an entry comment starting `UNPACK:` to the temp folder.
The existing Maven and Gradle plugins have been updated with new
configuration options and the `spring-boot-tools` project has been
updated to write the appropriate entry comment based on a flag passed
in via the `Library` class.
This support has been added to allow libraries such a JRuby (which
assumes that `jruby-complete.jar` is always accessible as file) to work
with Spring Boot executable jars.
Fixes gh-1070
Add a Library class update the LibraryCallback interface and
implementations to use it. This change is in preparation for
an addition `unpack` flag that will be required to allow the
automatic unpacking of certain nested jars.
