[-- Attachment #1: Type: text/plain, Size: 737 bytes --]

In preparing this package I've found that the python-build-system (not
sure about the others) defines the environment variable HOME as
"/homeless-shelter". However, that directory does not exist in the
build chroot. This is a problem for cython, because it wants to access
$HOME/.cython. Wouldn't it be better to point HOME to an existing
directory (created in the chroot) with suitable permissions?

I'm a little bit unsure about the name of the package. I've not
prefixed it with "python[2]-" as the program extends the Python
language and can work with both (2 and 3) Python version series.
However, the package installs files in
".../lib/python${version}/site-packages/...". The naming is in-line
with Debian naming.


Regards,
Fede

It's not a common need when building packages.  There are a few other
packages that need an existing, writable $HOME when building or testing.

What you did seems reasonable to me.

I don't see what prompts this new module.  Leftover from development?

The style in the rest of the file would dictate that the uri begin on
the same line as string-append.

If $HOME is only required for tests only, please make the setenv a
separate phase that comes just before the check phase.  See
e.g. duplicity or rdup in gnu/packages/backup.scm, or the definition of
python-2 itself.  We try to avoid "wrapping" phases with (apply <phase>
args).

Nitpicky: the lambda could probably go on a single line
(e.g. python-parse or python-enum34).

Does package-with-python2 not work here?  You might be able to do::

(define-public cython2
  (package (inherit (package-with-python2 cython))
    (name "cython2")))

OK. But if the directory would exist, then the build system would
cover more packages with no extra tweaking required.

Yes.

Yes, that's nicer. Changed.

Since there will be two packages, I suggest to follow our python module
naming conventions although this is not a python module, and to prepend
with "python-" and "python2-". Writing "cython2" would look as if this were
a next generation cython (in particular, it would look newer than plain
cython in version 0.21.1).

Concerning the following problem with python-wrapper:

Maybe we should propagate its input python? Then python-wrapper would
also install python instead of just adding a few links to the binaries.

From my point of view this would be desirable.  I'm having the same
problem with other packages such as numpy (which I'm preparing).

By the way, I've also noted another minor defect: the wrappers for
programs created by python-build-system puts double entries for some
directories in the definition of PYTHONPATH.  This is visible, e.g.,
in python-nose (nosetests), python-setuptools (easy_install),
python-cython and probably more.  This does not create problems, but
it would be nice to remove double entries.

Regards,
Fede

I think that should have gone on the wip-python branch eventually instead
of being pushed now... Never mind, we can always adapt it later!

Oh, apologies then.

But are you sure you aren’t confusing it with NumPy, which requires the
new python-wrapper?

Probably I am confusing things, even less problems then!

No, Andreas is right: this patch suffers from the same problem as Numpy.

Maybe I wasn't clear :-)  the patch does include python as an input.
So, it will build in master, without any change in python-wrapper.
After the changes in python-wrapper, we may want to remove the python
input.

Fede
