QUESTION
I am trying to access a java package loaded into memory and dump it to a file. Here is how the security works: there is an exe packed with Themida that contains the java main class code to be loaded. At runtime the Themida exe loads the clean main class java code into memory. The software is structured with the loader being contained within the exe, but several external libraries can access the packages contained within the exe. So, exe contains com.mysoft.mainloader. But the clean jar library Mylib.jar can call functions within com.mysoft.mainloader. How to I dump com.mysoft.mainloader to a jar file? Can I modify Mylib.jar to dump it as it has access to the package once it is loaded as well?
...ANSWER
Answered 2022-Apr-01 at 10:40There is no supported Java SE mechanism to read / retrieve a ".class" that has been loaded by a classloader. So your options would be:
Modify the custom classloader you are using to capture the ".class" before (or after) the classloader calls
defineClass
.Burrow into the JVM data structures to try and figure out whether the entire ".class" stream is captured somewhere and then retrieve it.
Modify the JVM ...
Any of these could be feasible. All will be relatively difficult.
QUESTION
I am trying to call a external stored procedure from Sql stored procedure by passing two parameters. one of the parameters is expected to return back with a string value, which when arrives I need to stop the data to be committed in any file.
To explain the situation - SP1 (SQL stored procedure) will call SP2 (External stored procedure), which will call RPGLE program PGM1, which will call another RPGLE program PGM2.
Now I am tasked to handle commitment control of File1 and File 2 used in PGM2 from SP1. If at any point File1 is updated and File2 gives an error while updating any record, data from File 1 should also be rolled back. but this rollback should happen in SP1.
So far I have tried to split this issue in two parts-
PARTA - How to Call External stored procedure from SQL stored procedure.
PARTB - How to handle commitment in SQL stored procedure in essence, if PGM2 gives back error data should be rolled back.
Below is the piece of code so far I have tried. But have no luck.

I need to create dynamic list of QObject*
(representin a custom model) and expose them to QML. The problem is that QML tries to re-use previously deleted QObject*
which ends up with errors at runtime:
ANSWER
Answered 2022-Mar-03 at 03:21Your code seems to be working fine. That's how Repeater works.
When your model is reset, Repeater starts to remove its QQuickItems one by one in reverse order.

QUESTION
My setup: main node runs on Linux and an agent on Windows. I want to compile a library on an agent, archive those artifacts and copy them on the main node to create a release togather with the Linux compiled binaries.
This is my Jenkinsfile
:
ANSWER
Answered 2022-Feb-19 at 22:24The copyArtifacts
capability is usually used to copy artifacts between different builds and not between agents on the same build. Instead, to achieve what you want you can use the stash and unstash keywords which are designed exactly for passing artifacts from different agents in the same pipeline execution:
stash: Stash some files to be used later in the build.
Saves a set of files for later use on any node/workspace in the same Pipeline run. By default, stashed files are discarded at the end of a pipeline run
unstash: Restore files previously stashed.
Restores a set of files previously stashed into the current workspace.
In your case it can look like:

I’m trying to come up with the Lua script that would work with both - SCRIPT LOAD/EVALSHA and FUNCTION LOAD/FCALL (New feature of Redis 7.0).
As I understand it now - all i need is to figure out the execution context - if script is being called as EVALSHA vs. FUNCTION LOAD.

As a first step, my test App is comprised of 2 files:
- Comp who exposes a doSomething() function
- App who need to trigger doSomething() in Comp as soon as possible (at the start of the app without any action from the user for example).
From what I know, this could be done like below (critiques are welcome here: pattern, coupling, effectiveness etc.)
part 1 (a bit of context)App.svelte

QUESTION
I want to redirect the stdout
and stderr
C streams to Java, but I am struggling to do so. I used the result of this thread: https://users.jna.dev.java.narkive.com/VdgNgCIb/jna-solutions-to-catch-stdout-stderr-of-dll but it still does not work as intended.
Here is my C code (I compiled it as a TestPrintf.dll
library):
ANSWER
Answered 2021-Dec-18 at 13:23If you have no control over the source code of your C library, I suggest writing a separate CLI C app that uses it, and capturing its stdout.
If you do have control over the source code of your C library, consider restructuring its API so that it's not necessary to capture stdout.
Doing what you're attempting right now is fragile and it will not pay off.
QUESTION
Update (1): The same problem can be seen with some compiled stdlib modules. This is not related to numpy (I'm removing the numpy tag and numpy from the title)
I'm writing a shared object (that is a plugin for a software) that contains an embedded python interpreter. The shared object launches an interpreter and the interpreter imports a python module to be executed. If the imported module includes numpy, I get an undefined symbol error. The actual undefined symbol error changes in function of the python version or numpy version, but it is always a struct of the PyExc_*
family.
I've simplified the issue to this mimimum example (it comprises actually two files):
...ANSWER
Answered 2021-Dec-17 at 09:08I've found a solution. Knowing that it was not tied to numpy halped quite a lot to switch the focus on the real problem: symbol missing. Taking the suggestion from this answer and in particular this point:
Solve a problem. Load the library found in step 1 by dlopen first (use RTLD_GLOBAL there as well).
I've modified the minimum example as follows:

Install MyLib
You can use MyLib like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
