magic command reset is not working

[dmytroxshevchuk]

I found that %reset -f command not working. I see in docs and in namespace.py file instruction how to use reset command and expected result, its looks like:

In [9]: %reset -f
In [1]: 

So I expect that after %reset -f command, number in [9] must be reset and will be [1].
In my case its looks like:

In [35]: %reset -f
In [36]:

So, this number is not reset after magic command. Arguments like --aggressive and -s is not help.

Also in docs I found that must be created new session:

By default (without this option), we do a ‘hard’ reset, giving you a new session and removing all references to objects from the current session.

But I go through the code and found that by default we send new_session = False:

ipython/IPython/core/magics/namespace.py

Lines 554 to 559 in 770024a

	if 's' in opts: # Soft reset
	user_ns = self.shell.user_ns
	for i in self.who_ls():
	del(user_ns[i])
	elif len(args) == 0: # Hard reset
	self.shell.reset(new_session=False, aggressive=("aggressive" in opts))

How can I restart session, reset [n] value or fully clear caches/modules without restart main application?

Judging by %reset docstring, this is a regression. And, wow, it's an old one.

• The new_session=False goes back to b24bd65 (10 years back). It's the first commit which breaks the magic.
• It works on the previous commit, a6a440b.

I'm not sure what's the context of the b24bd65 change. In any case, I think that given the docstring and the fact that, intuitively, a reset should get the console back to its initial state, I can safely mark this as a bug.

Currently new_session=True would also have a small quirk, where it resets to [2] instead of [1]. Something to look into if we ever get the True back. In Jupyter Notebook, the cell with %reset gets [1], which leads me to believe that simply, the new session starts before the counter is incremented, and the magic should prevent that somehow.
