guix depends on openldap?

[zimoun]

Dear,

This morning I garbage-collected some old items and pulled.  Well, I
was then  surprised that "guix environment guix" fetches 'openldap'.
Is it expected?

--8<---------------cut here---------------start------------->8---
$ guix graph -t bag --path guix openldap
guix@1.1.0-29.4e3ed9b
guile-ssh@0.13.1
libssh@0.9.5
cmake-minimal@3.16.5
curl@7.69.1
openldap@2.4.49
--8<---------------cut here---------------end--------------->8---

Why does curl need an "Implementation of the Lightweight Directory
Access Protocol"?


All the best,
simon

I think a better question is can cmake-minimal depend on a new
curl-minimal, or does it even need curl at all?

Looks like I was wrong, there is a curl-minimal afterall

guix size cmake-bootstrap       199.1 MiB
guix size cmake-minimal
    with curl-minimal           198.7 MiB
guix size cmake-minimal         214.9 MiB

We could probably remove ccmake and the share/cmake-<version> and drop
the size from 42M to about 21M.

HOWEVER, anything else that also depends on curl could depend on curl
and on curl-minimal, which would be worse than what we have now. So I'd
leave cmake-minimal with curl and remove the extra bits outlined below.

I am still confused.  Why cmake-minimal needs all the protocols that
curl supports?  What I was expecting is that cmake-minimal depends on
curl-minimal and that both packages are minimal. :-)
Because all in all, we end with a chubby Guix; which matters when
packing it (Docker or system).

All the best,
simon

I don't think it matters: no reference is retained from guix to openldap, so it won't be added to the pack or docker image. It's only required at build time.

So each time I run "guix environment guix", I potentially download it.
It is annoying when it is not possible to keep the store (for example,
the storage for the store is small or some CI external automation
build, etc.) or when the substitutes of dependencies are not available
(burn CPU) or when the bandwidth is not cheap, etc.

Maybe "packing it" is not the good terminology, but remove unnecessary
dependencies matters.  IMHO.


All the best,
simon

In the course of debugging the "32 bit ARM on 64 bit host can't read directories"
problem ("json-c") and starting to fix it, I had also asked myself that question.
I've researched back then why cmake needs curl in the first place and it turned
out it is in order to contact a CI dashboard server when tests run in ctest.

They do not support removing the library, but they do support disabling the
(or setting another) dashboard server to contact.
