tracing is a framework for instrumenting Rust programs to collect structured, event-based diagnostic information. tracing is maintained by the Tokio project, but does not require the tokio runtime to be used.

To what I understand, when you are trying to run manually there is no path set as the environment, and when you just do
python doesn't know in which environment we are running, which is precisely why, we do sys.path.append, to add the sibling directory path to env.
In the case if you are using an IDE like spyder or pycharm. you have an option to set the directory in which your program is located, or in pycharm it creates the whole program as a package where all the paths are handled by IDE.

The issue is that your compile SDK is 31, you are targetting API 31 (Android 12) and not setting the exported attribute.
You need to specify
android:exported="true" in the manifest.
If your app targets Android 12 and contains activities, services, or broadcast receivers that use intent filters, you must explicitly declare the android: exported attribute for these app components.

I have an java app (JDK13) running in a docker container. Recently I moved the app to JDK17 (OpenJDK17) and found a gradual increase of memory usage by docker container.
During investigation I found that the 'serviceability memory category' NMT grows constantly (15mb per an hour). I checked the page https://docs.oracle.com/en/java/javase/17/troubleshoot/diagnostic-tools.html#GUID-5EF7BB07-C903-4EBD-A9C2-EC0E44048D37 but this category is not mentioned there.
Could anyone explain what this serviceability category means and what can cause such gradual increase? Also there are some additional new memory categories comparing to JDK13. Maybe someone knows where I can read details about them.
Here is the result of command
jcmd 1 VM.native_memory summary
ANSWERAnswered 2022-Jan-17 at 13:38
Unfortunately (?), the easiest way to know for sure what those categories map to is to look at OpenJDK source code. The NMT tag you are looking for is mtServiceability. This would show that "serviceability" are basically diagnostic interfaces in JDK/JVM: JVMTI, heap dumps, etc.
But the same kind of thing is clear from observing that stack trace sample you are showing mentions
ThreadStackTrace::dump_stack_at_safepoint -- that is something that dumps the thread information, for example for
jstack, heap dump, etc. If you have a suspicion for the memory leak in that code, you might try to build a MCVE demonstrating it, and submitting the bug against OpenJDK, or showing it to a fellow OpenJDK developer. You probably know better what your application is doing to cause thread dumps, focus there.
That being said, I don't see any obvious memory leaks in
StackFrameInfo, neither can I reproduce any leak with stress tests, so maybe what you are seeing is "just" thread dumping over the larger and larger thread stacks. Or you capture it when thread dump is happening. Or... It is hard to say without the MCVE.
Update: After playing with MCVE, I realized that it reproduces with 17.0.1, but not with either mainline development JDK, or JDK 18 EA, or JDK 17.0.2 EA. I tested with 17.0.2 EA before, so was not seeing it, dang. Bisection between 17.0.1 and 17.0.2 EA shows it was fixed with JDK-8273902 backport. 17.0.2 releases this week, so the bug should disappear after you upgrade.
I've read the paper An inherently iterative computation of Ackermann's function, published by Grossman & Zeitman in which they present an algorithm which optimizes Ackermann's function.
We know that the Ackermann function produces the result in the subsequences A(m,n)
m=0: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,...
m=1: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18,...
m=2: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33,...
m=3: 5, 13, 29, 61, 125, 253, 509, 1021, 2045, 4093, 8189, 16381, 32765, 65533,...
m=4: 13, 65533,...
It's stated that the
Next array is to keep track of where we are in each subsequence, and the
Goal array is to keep track of where we need to reach before transferring the value just calculated to the next subsequence. And all it does is incrementing 1 to the value:

I've read over the paper to get a sense of what algorithm they're proposing, and it's actually not that bad when you get the hang of it.
The basic idea is the following. We have a two-argument version of the Ackermann function defined as follows:
- A(0, n) = n + 1
- A(i, 0) = A(i - 1, 1)
- A(i, n) = A(i - 1, A(i, n - 1))
The approach the authors suggest is essentially a space-optimized, bottom-up calculation of the Ackermann function. Rather than give the final version of their algorithm, let's see if we can instead derive it from the above rules. We'll imagine filling in a 2D table where each row corresponds to a different value of i and each column corresponds to a value of n. Following the convention from the paper, we'll place the row for i = 0 on top, like this:

these are the headers so that
zipkin can track individual requests. This application is responsible for their proper propagation. Additionally, they are request headers and not response header, so everything works fine.
It looks okay. First, let's start with what these requests are:
