Inconsistencies in Package Transformation?

[Phil Beadling <phil@beadling.co.uk>]

Hi all,

I've read through this link:
https://guix.gnu.org/manual/en/html_node/Package-Transformation-Options.html

But I seem to get unexpected outcomes in some examples - see below.

Any advice or confirmation that this is a bug or misuse by me?

Thanks,
Phil.

A simple case of package transformation without any dependencies seems to
work fine - for example, let's upgrade pandas to v1.1.5:

































*$ guix package -i python-pandas python -p ~/profiles/pandas-1.1.5
--with-git-url=python-pandas=https://github.com/pandas-dev/pandas.git
<https://github.com/pandas-dev/pandas.git>
--with-commit=python-pandas=v1.1.5 --without-tests=python-pandasThe
following packages will be installed:   python        3.8.2   python-pandas
1.1.5updating checkout of 'https://github.com/pandas-dev/pandas.git'.

pd.__version__'0+unknown'>>>*

The right commit is taken from github, and after the build we use the
profile to access our new version of pandas (the 0+unknown version I think
is caused by building from git).


Next, I try exactly the same transformation, but I want to instead build
one of my own applications which has python-pandas as propagated input.  My
understanding from the docs is this should work find as a deep
transformation should occur?



























*$ guix package -i foo python -p ~/profiles/foo-pandas-1.1.5
--with-git-url=python-pandas=https://github.com/pandas-dev/pandas.git

pd.__version__'1.1.2'>>>*

Everything looks to be going to plan, but when I import pandas using the
new profile I get version *1.1.2* - which is my standard untransformed
python-pandas package - no replacement has taken place, despite the process
reporting the correct location and commit id for the pandas checkout.


This either looks like a) a bug, or b) I've misunderstood the scope of the
transformation syntax.


One last detail - my own definiton of python-pandas v1.1.2 inherits from
the gnu package in Guix.  Whilst I inherit the name python-pandas the
actual package is called python-pandas-foo, and it is referenced in foo's
package's propagated inputs like this:
*("python-pandas" ,python-pandas-foo)*

Package definition snippet:










*(define-public python-pandas-foo  (package    (inherit python-pandas)
(version "1.1.2")    (source     (origin       (method url-fetch)
 (uri (pypi-uri "pandas" version))       (sha256        (base32
"0i0lbp26kzbq1qa4rv2s2r42m9d95svjrfflmi01plygla3zskxn")))) .... and so on*

I don't think this last detail should matter, but I include is as the only
other significant detail that may differ from other systems.
