Errors persisting entities with MapConfigKeys with BrooklynComponentTemplateResolver values #1422

Open sjcorbett opened 10 years ago

sjcorbett commented 10 years ago

Brooklyn can't persist entities that have MapConfigKeys with BrooklynComponentTemplateResolver values because they have a reference to a LocalManagementContext, which makes everything go haywire.

An example failing blueprint is:

name: Persist failure
services:
- type: brooklyn.entity.webapp.ControlledDynamicWebAppCluster
  initialSize: 0
  location:
    localhost
  memberSpec:
    $brooklyn:entitySpec:
      type: brooklyn.entity.webapp.tomcat.TomcatServer
      brooklyn.config:
        java.sysprops:
          brooklyn.example.db.url: $brooklyn:formatString("abcdef %s", "ghi")

Comment from @aledsage in brooklyncentral:

[2014-05-21T17:04:37+0100] <aled> Off top of my head, I thought XmlMementoSerializer.TaskConverter would handle that - if we come across a task that hasn't completed then we don't persist it currently. So it shouldn't get anywhere near trying to do LocalManagementContext. [2014-05-21T17:05:14+0100] <aled> But BrooklynComponentTemplateResolver isn't a task?

ahgittin commented 10 years ago

i've added a bunch of tests for DSL and rebing in #1426, including (disabled) io.brooklyn.camp.brooklyn.JavaWebAppWithDslYamlRebindIntegrationTest.testJavaWebWithMemberSpecRebind() which I think is the same error being reported here. I think the spec is the culprit, but I can't tell why.

The stack trace is useless. It would be nice to get proper trace showing the object trace but I don't see any way to hook in to XStream to allow that.

aledsage commented 10 years ago

note that brooklyn.entity.rebind.Dumpers.logUnserializableChains(...) (in src/test/java) is useful for seeing the chain of references leading to the unserializable object. We could do something like that using xstream rather than standard serialization. However, I'd be very hesitant to include it in non-test code.

ahgittin commented 10 years ago

trying a few things. logUnserializableChains complains about a bunch of stuff that isn't serializable but we don't really care, and some other things which it shouldn't be trying to get, but it's hard to find out what

bumping to 1.4.7, code seems a little easier to follow though no easy way to dive in and get errors. curiously it times out instead of failing with this example. and it gives me some other warnings which i can intercept, and among other things, it's letting me get some more detail of the problems:

ahgittin commented 10 years ago

i've added an xstream Converter which intercepts attempts to serialize managementContext instances. that makes the test pass, though with some concerning but very useful output:

          <transformer class="com.google.common.collect.Maps$7">
            <val_-function class="io.brooklyn.camp.brooklyn.spi.creation.BrooklynComponentTemplateResolver$1">
              <outer-class>
                <mgmt class="brooklyn.test.entity.LocalManagementContextForTests">default-management-context</mgmt>

this is inside the java system properties config key

ahgittin commented 10 years ago

the more i look at this it seems we need the mgmt there, or else some clever way it gets known/injected later (ThreadLocals?) so the initial hack of a ManagementContextConverter feels like the right thing

@aledsage wdyt?
