The _addThreadSample function is responsible for adding a sample to a specific
thread. It first checks if the thread exists in the thread_map dictionary.
If not, it creates a new thread using the _createtread function and assigns
it to the thread_map. Finally, it calls the 'addSample' method of the thread,
passing the thread name, stack, and timestamp.

Shouldn't it be '_createThread'?

Why is it like this?  What do you intend with the thread['addSample']
method?  Can it be simpler like a direct function call?

And more importantly, you'd better make each patch work properly.
AFAICS it won't do the job because both _createtread() and
thread['addSample'] are not implemented yet.

You can either move those definitions to this commit or have the
commit implementing them before this one.

Thanks,

Yes, it should be '_createThread'. I will fix it in the next version.

The purpose of the addSample function is to append stack frames to the
samples['data'] collection. While it could be implemented as a standalone
function, doing so would increase complexity due to shared properties
among threads such as pid, tid, and threadName. Although a decorator
could potentially address this, it would likely result in code that
is functionally and structurally similar. Alternatively, if addSample
were implemented as a separate function, the shared elements would need
to be repeatedly passed to the function.

Thanks, Preparing commit in series is new to me. I will try to fix
it in the next version.
