Class UpdateManager

java.lang.Object

org.nuxeo.connect.update.task.update.UpdateManager

public class UpdateManager
extends Object

Manage jar versions update.

To manipulate the jar version registry you need to create a new instance of this class.

If you want to modify the registry then you may want to synchronize the entire update process. This is how is done in the Task run method.

Only reading the registry is thread safe.

TODO backup md5 are not really used since we rely on versions - we can remove md5

Look if an update is required, taking into account the given UpdateOptions, the currently installed JAR and the other available JARs.

Parameters:

key -

opt -

currentJar -

Returns:

null if no update required, else the right UpdateOptions

Throws:

Since:

5.7

getRollbackTarget

public File getRollbackTarget(RollbackOptions opt)

Ugly method to know what file is going to be deleted before it is, so that it can be undeployed for hotreload.

FIXME: will only handle simple cases for now (ignores version, etc...), e.g only tested with the main Studio jars. Should use version from RollbackOptions

Since:

5.6

rollback

public void rollback(RollbackOptions opt)
              throws org.nuxeo.connect.update.PackageException

Perform a rollback.

TODO the deleteOnExit is inherited from the current rollback command ... may be it should be read from the version that is rollbacked. (deleteOnExit should be an attribute of the entry not of the version)

Parameters:

opt -

Throws:

org.nuxeo.connect.update.PackageException

rollbackBaseVersion

protected void rollbackBaseVersion(Entry entry,
                                   RollbackOptions opt)
                            throws org.nuxeo.connect.update.PackageException

Throws:

protected void rollbackVersion(Entry entry,
                               Version version,
                               RollbackOptions opt)

Throws:

getServerRelativePath

createEntry

public Entry createEntry(String key)
                  throws org.nuxeo.connect.update.PackageException

Create a new entry in the registry given the entry key. A base version will be automatically created if needed.

Parameters:

key -

Throws:

Exception

org.nuxeo.connect.update.PackageException

backupFile

protected void backupFile(File fileToBackup,
                          String path)
                   throws org.nuxeo.connect.update.PackageException

Backup the given file in the registry storage. Backup is not a backup performed on removed files: it is rather like a uniformed storage of all libraries potentially installed by packages (whereas each package can have its own directory structure). So SNAPSHOT will always be overwritten. Backup of original SNAPSHOT can be found in the backup directory of the stored package.

Parameters:

fileToBackup -

path -

Throws:

org.nuxeo.connect.update.PackageException

removeBackup

protected void removeBackup(String path)

Remove the backup given its path. This is also removing the md5.

Parameters:

path -

getBackup

protected File getBackup(String path)

getTargetFile

protected File getTargetFile(String path)

copy

protected void copy(File src,
                    File dst)
             throws org.nuxeo.connect.update.PackageException

Throws:

org.nuxeo.connect.update.PackageException

deleteOldFile

protected void deleteOldFile(File targetFile,
                             File oldFile,
                             boolean deleteOnExit)

findInstalledJar

public org.nuxeo.connect.update.task.update.JarUtils.Match<File> findInstalledJar(String key)

findBackupJar

                     UpdateOptions opt)
              throws org.nuxeo.connect.update.PackageException

Update oldFile with file pointed by opt

Throws:

org.nuxeo.connect.update.PackageException
