Embedded spaces with disabled Lookup Service in integration tests

I already posted a question how to disabled the Lookup service in my integration tests. http://ask.gigaspaces.org/question/99... Now the lookup service is disabled (I think) but this leads me to the next problem.

My test looks like this:
I have two embedded spaces using the setup code shown below.

  1. The production code starts a thread which starts a transaction and waits (blocking take) for an object written into Space-A
  2. I write this object into Space-A from the unit test runner thread
  3. The other thread takes it and converts it into another object and writes this other object into Space-B
  4. After it has written the converted object the transaction is commited
  5. Now I do a blocking take on Space-B (in the unt test runner thread) and wait until the converted object shows up

Unfortunetly I never see the converted object appearing in Space-B.
I checked the transaction commit and this seems to work (at least no exception appears).

I am currently creating the GigaSpace instances once and re-use the same instance in the code under test as well as the test code itself. What I mean is that I changed the dependency injection config of my production code classes to inject them the GigaSpace instance that I created in the test code. So I only create the instances once and re-use them. Can this be a problem?

I am still using the DistributedJiniTxManager, can this be a problem when using embedded spaces where the lookup service is disabled?

UrlSpaceConfigurer cfg = new UrlSpaceConfigurer("/./ProcuderSpace")
                .lookupGroups(environment.getEnvironmentVariableOrDefault(ENV_LOOKUP_GROUPS, LOOKUP_GROUPS_DEFAULT))
                .addProperty("space-config.lease_manager.expiration_time_interval", "1500")
                .addProperty("com.j_spaces.core.container.directory_services.jini_lus.start-embedded-lus", "false")
                .addProperty("com.j_spaces.core.container.directory_services.jini_lus.enabled", "false")
                .addProperty("com.j_spaces.core.container.directory_services.jndi.enabled", "false")
                .addProperty("com.j_spaces.core.container.embedded-services.httpd.enabled", "false");

txManager = new DistributedJiniTxManagerConfigurer().transactionManager();
GigaSpace gigaSpace = new GigaSpaceConfigurer(configurer).transactionManager(txManager).create();

EDIT: Also I get this exceptions with the config above:

Hi, You say you have 2 different spaces, Space A and Space B, How do you create the proxy to space B? did you make sure you are doing the blocking take on teh converted object on Space B and not A i suggest you add some filters to the space and print something before_write and after_write to make sure the objects are there, see more information here: http://docs.gigaspaces.com/xap97/the-...

I create the proxy as shown above (using the UrlSpaceConfigurer). I tried to use the same proxy instance in my production code but as I already said the writes did not show up when doing the take in the test runner thread. I also tried to create another proxy in my production code and use this to make the writes, I got the same problem.

I also tried to just write and read from Space B in the test code and this works.

I guess the problem has to do with the transaction manager because in the production code I write inside a transaction.

I will also try the filters now.

I dont really get how this UrlSpaceConfigurer works.. what happens if I execute the code above twice in a row (using exactly the same URL)? Does it just create two proxies to the same space or does it create two different spaces?

leozilla gravatar imageleozilla ( 2014-12-07 16:11:04 -0600 )edit

Running the code above twice will create 2 spaces, if you want to connect to the space and not create it you need to use a different url : jini:////ProcuderSpace

But I need to enable the LookupService when I use a jini url right? or can i just write "jini://?/SpaceName"? Btw: Does your url above use 4 slashes? what kind of url is that?

see here all the information about the space URL:http://docs.gigaspaces.com/xap97/the-space-configuration.html my suggestion is to use remote proxy to the space since you are running 2 different spaces, you need 2 separate space proxies If that does not work, i suggest we set up a webex and review the test code together and see how to resolve it, sounds OK?

Thanks for your answer. I have already read the documentation about the Space URL about 5 times but I dont really see howto create the proxies for multiple embedded spaces. I will try the remote proxy again.

The webex sounds really good I think it will help me and our team a lot! Are you a GigaSpace employe?

Yes, I am GigaSpaces employee. and i understand that Ron Z. from GigaSpaces also approached you and would like to assist you directly. please work with Ron on this issue as well. I will sync with Ron and post an answer here once this issue is resolved.
