Do not duplicate managed deployment in content repository in tmp/vfs/temp directory

XMLWordPrintable

      It looks like we have are duplicating deployments in the content repository when VFS mounts them.

      deploy a test app with jboss-cli.sh

      deploy helloWorld.ear

      The deployment gets uploaded into the content repository:

      $JBOSS_HOME/standalone/data/content/63/30e18e648eba2242f16bbe11a8eea0dcdb8a1d/content 
      ls standalone/tmp/helloWorld.ear.helloWorld.war/
[empty] 
      ls -r standalone/tmp/vfs/deployment/deployment9a5e4ddb6e3ea138/helloWorld*
standalone/tmp/vfs/deployment/deployment9a5e4ddb6e3ea138/helloWorld.war-20dcb94b1af44bbe:
index.jsp com WEB-INF META-INF
standalone/tmp/vfs/deployment/deployment9a5e4ddb6e3ea138/helloWorld-standalone-client.jar-863ffeb82cec36f5:helloWorld-standalone-client.jar contents
standalone/tmp/vfs/deployment/deployment9a5e4ddb6e3ea138/helloWorld-ejb.jar-2f9faedea31298d7:helloWorld-ejb.jar contents
standalone/tmp/vfs/deployment/deployment9a5e4ddb6e3ea138/helloWorld-api.jar-3a27e75ba1533497:
helloWorld-api.jar contents

       

      ls standalone/tmp/vfs/temp/temp6fb91ce22bbbf480/content-be5e0d197ed4d21f/contents/
[empty]

      Doing a shasum, I can see the standalone/data/content... file has the same hash as the VFS temp file tmp/vfs/temp/temp6fb91ce22bbbf480... , so this is a copy of the deployment, which is still compressed, thus it is doubling the disk space usage for this application.

      shasum standalone/data/content/63/30e18e648eba2242f16bbe11a8eea0dcdb8a1d/content standalone/tmp/vfs/temp/temp6fb91ce22bbbf480/content-be5e0d197ed4d21f/content
6330e18e648eba2242f16bbe11a8eea0dcdb8a1d  standalone/data/content/63/30e18e648eba2242f16bbe11a8eea0dcdb8a1d/content
6330e18e648eba2242f16bbe11a8eea0dcdb8a1d  standalone/tmp/vfs/temp/temp6fb91ce22bbbf480/content-be5e0d197ed4d21f/content

      The files / dirs under tmp/vfs/deployment/deployment9a5e4ddb6e3ea138 are the decompressed contents of application.

      Since we have to decompress, we will have 2 x file size (the content and the extracted dir), but it looks like we 3 x , with this extra content that looks like we could fix.
