Cannot load yaml data coming from Ansible: Number of aliases for non-scalar nodes exceeds the specified max=50

[tpegeot]

Hello,
I'm linking the issue rundeck/rundeck#9278 here as it seems related to the Ansible-plugin.

Describe the bug
I'm not able to load my Ansible inventory in Rundeck because of the following error :
[2024-09-26T08:46:25,397] ERROR resources.ExceptionCatchingResourceModelSource [NodeService-SourceLoader1] - [ResourceModelSource: 2.source (com.batix.rundeck.plugins.AnsibleResourceModelSourceFactory), project: Security_updates] com.dtolabs.rundeck.core.resources.ResourceModelSourceException: Cannot load yaml data coming from Ansible: Number of aliases for non-scalar nodes exceeds the specified max=50

Possible root cause
The amount of aliases for collections is set to 50 by default to avoid https://en.wikipedia.org/wiki/Billion_laughs_attack
See https://javadoc.io/static/org.yaml/snakeyaml/1.32/org/yaml/snakeyaml/LoaderOptions.html#setMaxAliasesForCollections-int-

Possible solution
I'm wondering if it would be possible to add a call to the setMaxAliasesForCollections function in ansible-plugin/src/main/groovy/com/rundeck/plugins/ansible/plugin/AnsibleResourceModelSource.java file in order to increase the default limit?

Thank you in advance

Thomas

Modifying the java code to set maxAliasesForCollections to an higher value (like 1000) seems to fix the problem. But I keep having java.lang.NullPointerException like in rundeck/rundeck#9278 (comment)

[madsi1m]

i had to do the same in #388

Hi @tpegeot
Is it possible for you to share a version of your inventory that produces the issue?
Thanks

Hi @ltamaster,

Here is a version of our inventory that produces the issue :
We still have the issue.

Hi @tpegeot Is it possible for you to share a version of your inventory that produces the issue? Thanks Luis

@ltamaster , ldimaur0 uploaded our inventory.

As mentioned earlier, setting maxAliasesForCollections to an higher value (like 1000) fixes the "Number of aliases for non-scalar nodes exceeds the specified max=50" problem.

However, we've not been able to fix the "null exception" error. We tried #388 but it didn't help.

@tpegeot ,could you share where we need to modify this value please ?

[tpegeot]

In src/main/groovy/com/rundeck/plugins/ansible/plugin/AnsibleResourceModelSource.java, I modified the ansibleInventoryList function :

   public void ansibleInventoryList(NodeSetImpl nodes, AnsibleRunner.AnsibleRunnerBuilder runnerBuilder) throws ResourceModelSourceException {

     int codePointLimit = yamlDataSize * 1024 * 1024;
+    int maxAliasesForCollections = 1000;

     LoaderOptions snakeOptions = new LoaderOptions();
     snakeOptions.setCodePointLimit(codePointLimit);
+    snakeOptions.setMaxAliasesForCollections(maxAliasesForCollections);
     Yaml yaml = new Yaml(new SafeConstructor(snakeOptions));
