Subject: bluez or jack in the closure of python-ipython?
Date: Wed, 13 Sep 2023 15:33:04 +0200

Hi,

IPython is a Python REPL and there is no direct dependencies on bluez or
jack.  Why does it need unrelated tools as some Bluetooth or JACK audio?

--8<---------------cut here---------------start------------->8---
$ guix size python-ipython | grep -E '(jack|bluez)'
/gnu/store/kbvyzkxrpf8w9v64jvjkr12hcailhflx-bluez-5.66             192.8     4.3   0.2%
/gnu/store/7bhggk7fzvgjvgi9ykphgg21gwlfgx4k-jack-0.125.0            90.8     1.3   0.1%
--8<---------------cut here---------------end--------------->8---

Well, any idea why bluez or jack are in the picture?

--8<---------------cut here---------------start------------->8---
$ for p in $(guix show python-ipython | recsel -C -P dependencies); do guix size $p ;done | grep -E '(bluez|jack)'
… nothing!
--8<---------------cut here---------------end--------------->8---

Last, the chain of dependencies looks like:

--8<---------------cut here---------------start------------->8---

python-ipython <at> 8.5.0
python-matplotlib <at> 3.5.2
python-wxpython <at> 4.2.0
wxwidgets <at> 3.2.2.1
sdl2 <at> 2.26.2

bluez <at> 5.66

Seem pretty self-explanatory:
matplotlib has a GUI frontend (or even multiple frontends), one of them
is based on WxWidgets, which pulls in SDL2, and Guix doesn't split SDL2
like some other distros do, so all its dependencies get pulled in.
In case you are not familiar with SDL(2), it's a portable "direct media
layer", a library used for portable multimedia applications.

So could you explain why bluez is not in the closure python-matplotlib?

And then why it is in the closure of python-ipython?

And as I pointed, bluez is not in the closure of any dependencies of
python-ipython.

Cheers,
simon

Oh, bluez I have no idea about. :|
That is super weird.
