wso2-puppet variable scope - wso2

I'm trying to deploy WSO2 products using puppet (v 3.8.7, master/agent setup) and provided puppet scripts. Apart small details ( undefined wso2::hosts_template variable, usage of ensure_resource , ...), my fact tests are blocked with undefined template variables.
In my role definition I create a new products instance, e.g.
class { 'wso2am':
}
and I set a few facts:
product_name: wso2am
product_version: 2.0.0
product_profile: default
platform: default
vm_type:
which should install the wso2am with default settings
The error message is as follows:
undefined method `each' for nil:NilClass
(erb):25:in `get_binding'
/nix/store/xivrmfsyc7dc52m1zv1g52ziwjag5n4f-ruby-2.3.3/lib/ruby/2.3.0/erb.rb:864:in `eval'
...
in ./modules/wso2am/templates/2.0.0/repository/conf/datasources/am-datasources.xml.erb at # SourcePos {sourceName = "./modules/wso2base/manifests/push_templates.pp", sourceLine = Pos 26, sourceColumn = Pos 10}
where I believe the template parameter am_datasources is undefined. Indeed I see in the modules/wso2base/manifest/init.pp the parameter is loaded from the hieradata, but the template parameters (am_datasources is only one of them) are never passed to the invoked defines (wso2base::push_templates) directly.
Does the script assume some environmental setup or extra data visibility?

It should work if you have am_datasources defined in default.yaml like this.

AWS Lambda : how to handle a code asset defined by an environment variable that does not exist yet?

I (try to) deploy my current application using CDK pipelines.
In doing so, I stumbled across an unexpected behavior (here if interested) which now I am trying to resolve. I have a Lambda function for which the asset is a directory that is dynamically generated during a CodeBuild step. The line is currently defined like this in my CDK stack :
code: lambda.Code.fromAsset(process.env.CODEBUILD_SRC_DIR_BuildLambda || "")
The issue is that locally, this triggers the unexpected and undesired behaviour because the environment variable does not exist and therefore goes to the default "".
What is the proper way to avoid this issue?
Thanks!
Option 1: Set the env var locally, pointing to the correct source directory;
CODEBUILD_SRC_DIR_BuildLambda=path/to/lambda && cdk deploy
Option 2: Define a dummy asset if CODEBUILD_SRC_DIR_BuildLambda is undefined
code: process.env.CODEBUILD_SRC_DIR_BuildLambda
? lambda.Code.fromAsset(process.env.CODEBUILD_SRC_DIR_BuildLambda)
: new lambda.InlineCode('exports.handler = async () => console.log("NEVER")'),

How to get Instance name in CommandBox CF 2018?

I recently started using commandBox to run ColdFusion in my local environment. After I played around for a while one issue I run into was related to adminapi. Here is the code that I use in one of my projects:
adminObj = createObject("component","cfide.adminapi.runtime");
instance = adminObj.getInstanceName();
This code is pretty straight forward and work just fine if I install traditional ColdFusion Developer version on my machine. I tried running this on commandBox: "app":{ "cfengine":"adobe#2018.0.7" }
After I run the code above this is the error message I got:
Object Instantiation Exception.
Class not found: com.adobe.coldfusion.entman.ProcessServer
The first debugging step was to check if component exists. I simply checked that like this:
adminObj = createObject("component","cfide.adminapi.runtime");
writeDump(adminObj);
The result I got on the screen was this:
component CFIDE.adminapi.runtime
extends CFIDE.adminapi.base
METHODS
Then I tried this to make sure method exists in the scope:
adminObj = createObject("component","cfide.adminapi.runtime");
writeDump(adminObj.getInstanceName);
The output looks like this, and that confirmed that method getInstanceName exists.
function getInstanceName
Arguments: none
ReturnType: any
Roles:
Access: public
Output: false
DisplayName:
Hint: returns the current instance name
Description:
The error is occurring only if I call the function getInstanceName(). Does anyone know what could be the reason of this error? Is there any solution for this particular problem? Like I already mentioned this method works in traditional ColdFusion 2018 developer environment. Thank you.
This is a bug in Adobe ColdFusion. The CFC you're creating is trying to create an instance of a specific Java class. I recognize the class name com.adobe.coldfusion.entman.ProcessServer as being related to their enterprise manager which controls features only available in certain versions of CF as well as features only available on their "standard" Tomcat installation (as opposed to a J2E deployment like CommandBox).
Please report this to Adobe in the Adobe bug tracker as they appear to be incorrectly detecting the servlet installation. I worked with them a couple years ago to improve their servlet detection on CommandBox, but I guess they still have some issues.
As a workaround, you could try and find out what jar that class is from on a non-CommandBox installation of Adobe ColdFusion and add it to the path, but I can't promise that it will work and that it won't have negative consequences.

Cannot build Corda (release/os/4.6) on Ubuntu 20.04 due to failing tests (CryptoUtilsTest & NodeH2SecurityTests)

I am trying to build Corda on Ubuntu 20.04. I have the latest sources from the git repo (release/os/4.6) and I run ./gradlew build in the main folder. However the build fails during two tests (see the detail description below). Is there something that I'm missing? Are there some special flags that I should use for building Corda?
First, the test test default SecureRandom uses platformSecureRandom fails at the last assert, i.e.,
// in file net/corda/core/crypto/CryptoUtilsTest.kt
fun `test default SecureRandom uses platformSecureRandom`() {
// [...]
// Remove Corda Provider again and add it as the first Provider entry.
Security.removeProvider(CordaSecurityProvider.PROVIDER_NAME)
Security.insertProviderAt(CordaSecurityProvider(), 1) // This is base-1.
val secureRandomRegisteredFirstCordaProvider = SecureRandom()
assertEquals(PlatformSecureRandomService.algorithm, secureRandomRegisteredFirstCordaProvider.algorithm)
}
The reason for the failed test is Expected <CordaPRNG>, actual <SHA1PRNG>..
For some reason, the test is successful if before inserting the provider, I call the getServices() method, i.e.,
val provider = CordaSecurityProvider()
provider.getServices()
Security.insertProviderAt(provider, 1) // This is base-1.
I also tried to get the service SecureRandom.CordaPRNG directly from the provider and it works, i.e,
println(provider.getService("SecureRandom", "CordaPRNG"))
prints out Corda: SecureRandom.CordaPRNG -> javaClass
Second, the test h2 server on the host IP requires non-default database password fails since it expects a CouldNotCreateDataSourceException, but it gets a NullPointerException instead, i.e.,
// in file net/corda/node/internal/NodeH2SecurityTests.kt
fun `h2 server on the host IP requires non-default database password`() {
// [...]
address = NetworkHostAndPort(InetAddress.getLocalHost().hostAddress, 1080)
val node = MockNode()
val exception = assertFailsWith(CouldNotCreateDataSourceException::class) {
node.startDb()
}
// [...]
}
The problem is that the address is 127.0.1.1:1080, which means that net/corda/node/internal/Node.kt::startDatabase() does not throw CouldNotCreateDataSourceException since the condition to enter the branch
if (!InetAddress.getByName(effectiveH2Settings.address.host).isLoopbackAddress
&& configuration.dataSourceProperties.getProperty("dataSource.password").isBlank()) {
throw CouldNotCreateDataSourceException()
}
is not satisfied. Instead it calls toString() on the parent of the path given by the DB name; the parent is null, and thus, it throws NullPointerException, i.e.,
val databaseName = databaseUrl.removePrefix(h2Prefix).substringBefore(';')
// databaseName=my_file
val baseDir = Paths.get(databaseName).parent.toString()
Unfortunately there't a LOT of reasons that building Corda from source might not work.
Here are my recommendations:
it could be a java issue, there's a docs page on the specific version of java 8 that you need to use, (latest java support is on the roadmap for corda 5 🔥) Here's the docs page on that https://docs.corda.net/docs/corda-os/4.5/getting-set-up.html
Like Alessandro said, you'll want to be aware that 4.6 isn't generally available yet so there may well be bugs and problems in the code until the release. In addition just take another look at the docs page on building corda (here: https://docs.corda.net/docs/corda-os/4.5/building-corda.html#debianubuntu-linux), it's mentioned to use 18.04 but not the latest linux, as there might be some random clib things that could get in the way there.
Good luck to you.

Swashbuckle (non-Core) configuration modification at runtime

Using the non-Core version of Swashbuckle (https://github.com/domaindrivendev/Swashbuckle), is there a way to modify the configuration after the application has launched? I cannot find a way to do this out of the box.
As an example, let's say I want to modify this at some point while the application is running:
.EnableSwaggerUi(c =>
{
c.SupportedSubmitMethods("GET");
});
Is this possible without modifying Swashbuckle itself?
Look into IDocumentFilters they get executed at runtime.
I have a few examples here:
SwashbuckleTest/blob/master/Swagger_Test/App_Start/SwaggerConfig.cs
And that EnableSwaggerUi( c => SupportedSubmitMethods ) is something that happens on the browser client side, you can change that behavior with a custom JS file, look in the config for InjectJavaScript.
You can also overwrite the default assets used in the swagger-ui (such as the index.html) with your own version, look in the config for CustomAsset

How to increase deploy timeout limit at AWS Opsworks?

I would like to increase the deploy time, in a stack layer that hosts many apps (AWS Opsworks).
Currenlty I get the following error:
Eror
[2014-05-05T22:27:51+00:00] ERROR: Running exception handlers
[2014-05-05T22:27:51+00:00] ERROR: Exception handlers complete

[2014-05-05T22:27:51+00:00] ERROR: deploy[/srv/www/lakers_test] (opsworks_delayed_job::deploy line 65) had an error: Mixlib::ShellOut::CommandTimeout: Command timed out after 600s:
Thanks in advance.
First of all, as mentioned in this ticket reporting a similar issue, the Opsworks guys recommend trying to speed up the call first (there's always room for optimization).
If that doesn't work, we can go down the rabbit hole: this gets called, which in turn calls Mixlib::ShellOut.new, which happens to have a timeout option that you can pass in the initializer!
Now you can use an Opsworks custom cookbook to overwrite the initial method, and pass the corresponding timeout option. Opsworks merges the contents of its base cookbooks with the contents of your custom cookbook - therefore you only need to add & edit one single file to your custom cookbook: opsworks_commons/libraries/shellout.rb:
module OpsWorks
module ShellOut
extend self
# This would be your new default timeout.
DEFAULT_OPTIONS = { timeout: 900 }
def shellout(command, options = {})
cmd = Mixlib::ShellOut.new(command, DEFAULT_OPTIONS.merge(options))
cmd.run_command
cmd.error!
[cmd.stderr, cmd.stdout].join("\n")
end
end
end
Notice how the only additions are just DEFAULT_OPTIONS and merging these options in the Mixlib::ShellOut.new call.
An improvement to this method would be changing this timeout option via a chef attribute, that you could in turn update via your custom JSON in the Opsworks interface. This means passing the timeout attribute in the initial Opsworks::ShellOut.shellout call - not in the method definition. But this depends on how the shellout method actually gets called...
