    Hot-deployment on AS 5.x

    Jesper Pedersen Master

      I get stack traces when I hot-deploy on AS 5.x (currently rev88714 using VFS-2.1.1.GA).

      Sample application is the web ui for JBoss Profiler 2 - a .WAR file around 6MB - deployment is done in non-exploded format. The stack traces can be easy triggered if the deployments are done in a tight loop.

      Here is one:

          Might be related to the HDScanner picking up the deployment before the copy of the war, to the deploy folder, is complete. One way to verify this would be to increase the HDScanner timeout to a higher value (which will reduce the chances of picking up the stale deployment -though it can't be completely ruled out):


          <!--Increase to a higher value -->
          <property name="scanPeriod">5000</property>

            Users shouldn't have to worry about the scanPeriod parameter - a deployment should be an atomic operation.

              Yep. But i think the issue is:

              1) A OS copy operation is in progress
              2) HDScanner wakes up and does a check for new file availability
              3) OS says new file available, even though copy is not complete (i remember this on Windows, not sure about other OS)
              4) HDScanner starts processing the deployment while the file is still being copied
              5) HDScanner blows up with exception since its a corrupt file.

              And i guess, we will be able to reproduce this on JBossAS-4.x too.

                    Moving our email discussion to the forum.

                    Jesper, me and Emanuel were seeing a JVM crash when the application was hot-deployed in a tight loop. This issue (the JVM crash and neither the IOException) does not occur in AS-4.2.x (not yet sure why) but appears to be happening in AS-5. Here's some details:

                    I have managed to narrow this down to the VFS handling of ZipFile(entries). Having said that, i would not have expected the JVM to crash, but throw an IOException (as you first reported in the JIRA). Here's what's happening:

                    1) HDScanner picks up the archived deployment (.war)
                    2) VFS starts temping this by extracting the contents of the .war (ZipEntryHandler class). Internally it opens a InputStream for the zip entries.
                    3) When this processing is in progress, if we hot deploy the .war again, the InputStream that VFS is processing on, becomes stale (and ideally should throw IOException).
                    4) Finally the error.

                    Just to check whether i was guessing this right, i deployed the .war in exploded format and i could see that it moved past this and failed a bit later where VFS tried to work on the WEB-INF/lib/*.jar entries (the same zip entry processing logic with the InputStream). It failed with the same JVM crash here too.

                    So finally just to test, i removed all the jars from the lib folder, updated the web.xml to just contain the welcome-file section and deployed the war in exploded format. All this to ensure that no zip file processing happens. After this, i can successfully deploy this application in a tight loop without any issues - but obviously, this application is now of no use without any of its functionalities :)

                    Now that it's been tracked down to the zip file handling, i am going to see how JBossAS-4.x handles this, since we don't see this issue there.

                    P.S: The java dump during the crash helped in narrowing down this issue:

                      Looks similar. Shelly mentions in that issue that it works on JRockit, so let me give it a try against that and see what the behaviour is.

                        JRockit handles this better - it does not crash and throws this exception which is expected:

                          I am facing the same issue.
                          I am having a script doing a daily deployment/undeployment of the app.
                          For the first week, things were going fine.
                          Now startup/deployment fails with almost the same stacktrace

                          Any idea if this will this be fixed in the next release?

                            This does not look like the same issue. Can you please create a separate thread in the JBoss AS5 forum http://www.jboss.org/index.html?module=bb&op=viewforum&f=287. When you create the thread there, please provide more details including the exact version of JBossAS, the version and vendor of Java and the entire exception stacktrace. Also please provide more details about how you deploy/undeploy/redeploy.
