This is a problem that has been really puzzling. For some reason, equals method fails here:
val newItem = testPlaylistItem.copy(id = returnedItem.id, index = 0, updatedAt = newPlaylistFromDb.updatedAt)
assertEquals(newPlaylistFromDb, newItem)
As you can see, I'm just overwriting some properties that I know that change and I can't control (id isn't known since it's generated by the persistence and index and updatedAt are internally generated). Basically what I'm doing is ignoring them for the test at hand. This test is successful locally all the time but randomly fails when run by the compilation inside a Docker container (in CI pipeline). As displayed in the error, it shows a small difference: 2022-06-20T15:50:45.187Z vs 2022-06-20T15:50:45.186Z.
What I've tried so far is decompiling the generated bytecode into Java and I can't see the reason why this could happen. Apparently the copy method would pass the instant parameter by reference to instantiate a new object.
The stack and versions I'm using are:
Docker image: openjdk:11.0.3-jre-slim
Gradle 6.9.2
Kotlin 1.4.10

My issue resides on the fact that when I invoke via Jinja the variable {{ flags.WHICH}} it returns no output.
I am trying to use this variable to get what type of command the DBT is running at the moment, either a run, a test, generate, etc.
I am using the version dbt 0.18.1 with the adapter SPARK
flags.WHICH was not introduced until dbt 1.0. You'll have to upgrade to get that feature. Here is the source for the flags module, if you're interested about the flags available in your version.
Note that in jinja, referencing an undefined variable simply templates to the empty string, and does not raise an exception.
I am trying to create a cache of POD6 by precompiling them using the CompUnit set of classes.
I can create, store and retrieve pod as follows:
use v6.c;
use nqp;
my $precomp-store = CompUnit::PrecompilationStore::File.new(prefix=>'cache'.IO);
my $precomp = CompUnit::PrecompilationRepository::Default.new(store=> $precomp-store );
my $key = nqp::sha1('test.pod6');
'test.pod6'.IO.spurt(q:to/CONTENT/);
=begin pod
=TITLE More and more
Some more text
=end pod
CONTENT
$precomp.precompile('test.pod6'.IO, $key, :force);
my $handle = $precomp.load($key, )[0];
my $resurrected = nqp::atkey($handle.unit,'$=pod')[0];
say $resurrected ~~ Pod::Block::Named;
So now I change the POD, how do I use the :since flag? I thought that if :since contains a time after the compilation, then the value of the handle would be Nil. That does not seem to be the case.
my $new-handle = $precomp.load($key, :since('test.pod6'.IO.modified));
say 'I got a new handle' with $new-handle;
Output is 'I got a new handle'.
What I am doing wrong?
Here is a pastebin link with code and output: https://pastebin.com/wtA9a0nP
Module loading code caches look ups and essentially start with:
$lock.protect: {
return %loaded{$id} if %loaded{$id}:exists;
}
So the question becomes "how do I load a module and then unload it (so i can load it again)?" to which the answer is: you cannot unload a module. You can however change the filename, distribution longname ( via changing the name, auth, api, or version ), or precomp id -- whatever a specific CompUnit::Repository uses to uniquely identify modules -- to bypass the cache.
What seems to be overlooked is that $key is intended to represent an immutable name, such that it will always point at the same content. What version of foo.pm should be loaded for Module Used::Inside::A if foo.pm is being loaded by Module A and B at the same time, Module A loads foo first, and then Module B modifies foo? The old version Module A loaded, or the ( possibly conflicting with previous version ) Module B loaded version? And how would this differentiation work for precomp file generation themselves ( which again can happen in parallel )?
Of course if we ignore the above we could add code to make expensive .IO.modified calls for every single module load for all CompUnit::Repository types ( slowing down startup speed ) to say "hey this immutable thing changed". But the granularity of file system modified timestamps on some OS's made the check pretty fragile ( especially for multi-threaded module loading with precomp files being generated ), meaning that even more expensive calls to get a checksum would be necessary every single time.
I'm using Jmeter to design a test that requires data to be randomly read from text files. To save memory, I have set up a "setUp Thread Group" with a BeanShell PreProcessor with the following:
//Imports
import org.apache.commons.io.FileUtils;
//Read data files
List items = FileUtils.readLines(new File(vars.get("DataFolder") + "/items.txt"));
//Store for future use
props.put("items", items);
I then attempt to read this in my other thread groups and am trying to access a random line in my text files with something like this:
(props.get("items")).get(new Random().nextInt((props.get("items")).size()))
However, this throws a "Typed variable declaration" error and I think it's because the get() method returns an object and I'm trying to invoke size() on it, since it's really a List. I'm not sure what to do here. My ultimate goal is to define some lists of data once to be used globally in my test so my tests don't have to store this data themselves.
Does anyone have any thoughts as to what might be wrong?
EDIT
I've also tried defining the variables in the setUp thread group as follows:
bsh.shared.items = items;
And then using them as this:
(bsh.shared.items).get(new Random().nextInt((bsh.shared.items).size()))
But that fails with the error "Method size() not found in class'bsh.Primitive'".
You were very close, just add casting to List so the interpreter will know what's the expected object:
log.info(((List)props.get("items")).get(new Random().nextInt((props.get("items")).size())));
Be aware that since JMeter 3.1 it is recommended to use Groovy for any form of scripting as:
Groovy performance is much better
Groovy supports more modern Java features while with Beanshell you're stuck at Java 5 level
Groovy has a plenty of JDK enhancements, i.e. File.readLines() function
So kindly find Groovy solution below:
In the first Thread Group:
props.put('items', new File(vars.get('DataFolder') + '/items.txt').readLines()
In the second Thread Group:
def items = props.get('items')
def randomLine = items.get(new Random().nextInt(items.size))
What I want to do?
I want to create and consume java objects in PowerBuilder and call methods on it. This should happen with less overhead possible.
I do not want to consume java webservices!
So I've a working sample in which I can create a java object, call a method on this object and output the result from the called method.
Everything is working as expected. I'm using Java 1.8.0_31.
But now I want to attach my java IDE (IntelliJ) to the running JVM (started by PowerBuilder) to debug the java code which gets called by PowerBuilder.
And now my question.
How do I tell PowerBuilder to add special options when starting the JVM?
In special I want to add the following option(s) in some way:
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
The JVM is created like following:
LONG ll_result
inv_java = CREATE JavaVM
ll_result = inv_java.CreateJavaVM("C:\Development\tms java\pbJavaTest", FALSE)
CHOOSE CASE ll_result
CASE 1
CASE 0
CASE -1
MessageBox ( "", "jvm.dll was not found in the classpath.")
CASE -2
MessageBox ( "", "pbejbclient90.jar file was not found." )
CASE ELSE
MessageBox ( "", "Unknown result (" + String (ll_result ) +")" )
END CHOOSE
In the PowerBuilder help I found something about overriding the static registry classpath. There is something written about custom properties which sounds like what I'm looking for.
But there's no example on how to add JVM options to override default behavior.
Does anyone have a clue on how to tell PowerBuilder to use my options?
Or does anyone have any advice which could guide me in the right direction?
Update 1
I found an old post which solved my initial issue.
If someone else want to know how it works take a look at this post:

Hi, you need to set some windows registry entries.
Under HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\Powerbuilder\9.0\Java, there
are two folders: PBIDEConfig and PBRTConfig. The first one is used when
you run your application from within the IDE, and the latter is used
when you run your compiled application. Those two folders can have
PBJVMconfig and PBJVMprops folders within them.
PBJVMconfig is for JVM configuration options such as -Xms. You have to
specify incremental key values starting from "0" by one, and one special
key "Count" to tell Powerbuilder how many options exists to enumerate.
PBJVMprops is for all -D options. You do not need to specify -D for
PBJVMProps, just the name of the property and its value, and as many
properties as you wish.
Let me give some examples:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\PowerBuilder\9.0\Java\PBIDEConfig\PBJVMprops]
"java.security.auth.login.config"="auth.conf"
"user.language"="en"
[HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\PowerBuilder\9.0\Java\PBRTConfig\PBJVMconfig]
"0"="-client"
"1"="-Xms128m"
"2"="-Xmx512m"
"Count"="3"
[HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\PowerBuilder\9.0\Java\PBRTConfig\PBJVMprops]
"java.security.auth.login.config"="auth.conf"
"user.language"="en"

But now there's another issue...
PB isn't able to create EJB Proxies for my sample class which is really simple with java 1.8.0_31. They were created with the default version, which is 1.6.0_24.
public class Simple
{
public Simple()
{
}
public static String getValue()
{
return "blubber";
}
public int getInt32Value()
{
return 123456;
}
public double getDoubleVaue()
{
return 123.123;
}
public static void main(String[] args)
{
System.out.println(Simple.getValue());
}
}
The error is the following. :D
---------- Deploy: Deploy of project p_genapp_ejbclientproxy (15:35:18)
Retrieving PowerBuilder Proxies from EJB...
Generation Errors: Error: class not found: (
Deployment Error: No files returned for package/component 'Simple'. Error code: Unknown. Proxy was not created.
Done.
---------- Finished Deploy of project p_genapp_ejbclientproxy (15:35:19)
So the whole way isn't a option because we do not want to change the JAVA settings in PB back and forth just to generate new EJB Proxies for changed JAVA objects in the future...
So one option to test will be creating COM wrappers for JAVA classes to use them in PB...
I have a build that uses EnvInject Plugin to set an environmental value.
A different job needs to scan last good Jenkins build of that job and get the value of that environmental variable.
This all works well, except sometimes the variable will disappear from build history. It seems that after some time passes, when I look at the 'Environment variables' section in build history, the injected value simply disappears.
How can I make this persist? Is this a bug, or part of the design?
If it make any difference, the value of the injected variable is +1500 chars and in the following format: 'component1=1.1.2;component2=1.1.3,component3=4.1.2,component4=1.1.1,component4=1.3.2,component4=1.1.4'
Looks like EnvInject and/or JobDSL have a bug.
Steps to reproduce:
Set up a job that runs this JobDSL:
job('run_deploy_mock') {
steps {
environmentVariables {
env('deployedArtifacts', 'component1=1.0.0.2')
}
}
}
Run it and it will create a job called 'deploy_mock'
Run the 'deploy_mock' job. After build #1 is done, go to build details and check 'Environmental Variables' section for an entry called 'component1'
Run the JobDSL job again
Check 'Environmental Variables' section for 'deploy_mock' build #1. The 'component1' variable is now missing.
If I substitute the '=' for something else, it works as expected.
