Boes updated GERONIMODEVTOOLS-608:
----------------------------------
Attachment: HiThereSlow.ear
HiThere.ear
The only difference between the two EAR's is in the geronimo-application.xml.
The HiThereSlow has dependencies to existing libraries in the Geronimo
repository. HiThere does not have a depencies tag in it's
geronimo-application.xml.
> Publish with GEP takes minutes, while deploy takes seconds

> Project: Geronimo-Devtools
> Issue Type: Bug
> Components: eclipse-plugin
> Affects Versions: 2.2.0
> Environment: GEP 2.2 installed in Eclipse (galileo-SR1).

> Publishing an Enterprise Application (EAR) with GEP to Geronimo takes much
> more time then deploying the same EAR to Geronimo using the console. See
> http://n3.nabble.com/Publish-with-GEP-takes-minutes-while-deploy-takes-10-seconds-td684484.html
> After doing some research I found that EAR's that have dependencies in
> geronimo-application.xml take a lot of time to publish. This is caused by the
> very inefficient implementation of the reorderModules method in the
> org.apache.geronimo.st.core.internal.DependencyHelper class.
> I installed a GEP development environment and put on tracing. It tested an
> EAR with 3 WAR's in it. In the EAR's geronimo-application.xml I added
> dependency tags for 4 libraries. Tracing shows that this results in parsing
> the geronimo-application.mxl 1092 (!) times. In code this means that a call
> to DependencyHelper.getEnvironment is made 1092 times.
> Another inefficient part in the reorderModules method is that the call to
> DeploymentUtils.isInstalledModule is repeatedly made for the same module. In
> the test I found it was called at least 3 times for each dependent library.
> These calls result in a request to Geronimo and take almost a second each.
> The best way to solve this bug is to redesign the reordering process and make
> it work in a way that both DependencyHelper.getEnvironment and
> DeploymentUtils.isInstalledModule are not called more often then needed. I
> wonder why DeploymentUtils.isInstalledModule is called at all.
> What I did to fix this problem and make GEP workable again for me is:
> - made sure the DeploymentUtils.isInstalledModule is never called twice for
> the same module. Once the DeploymentUtils.isInstalledModule is called for a
> certain module, I add this module to a list. Before a next call to
> DeploymentUtils.isInstalledModule I verify if the call has been made before.
> If so, it doesn't need to be called again.
> - reduced the number of times the xml is parsed. I put the results of the
> DependencyHelper.getEnvironment for a certain module in a hashmap. Next time
> the DependencyHelper.getEnvironment is called for the same module, I return
> the result stored in the hashmap.
> After these two modifications GEP is up to speed again.
