setup.py: add "wheel" to setup_requires #349

Do you know why this dependency is necessary? It looks like Python is trying to build a wheel here, but the wheel library doesn't exist, which seems like a strange situation.

Does this only happen if you install nmigen from git in virtualenv, and not otherwise?

The default __repr__() from typing.NamedTuple does not include the module name, so the replacement (which uses the preferred syntax for specifying these shapes) doesn't either.

Fixes #326.

Fixes #353.

Fixes #147.

Also known as word_select().

Before this commit, selecting a part that was fully out of bounds of a value was correctly implemented as a write to a dummy wire, but selecting a part that was only partially out of bounds resulted in a crash. Fixes #351.

Such wires are likely to trigger pathological behavior in Yosys and, if applicable, other toolchains that consume Verilog converted from RTLIL. Fixes #341.

Fixes #335.

By default, if an operation produces an undefined value (a Jinja2 concept that corresponds to Python's KeyError, AttributeError, etc) then this value may be printed in a template, which is a nop. This behavior can hide bugs. This commit changes the Jinja2 behavior to raise an error instead of producing an undefined value in all cases. (We produce undefined values deliberately in a few places. Those are unaffected; it is OK to use several kinds of undefined values in one Jinja2 environment.) Fixes #337.

FFY00 · 2020-04-14T11:36:14Z

This does not belong in setup_requires, at most, it would be in extras_require. Although, I can't reproduce, it seems like a bug in your setup.

mithro · 2020-04-14T15:22:33Z

I think this is a difference between virtualenv and venv (which are confusingly different tools). venv doesn't install wheel into the environment by default it seems while virtualenv does. I think virtualenv --no-wheel would give you the same behaviour as venv.

FFY00 · 2020-04-14T16:23:40Z

I created the environment with venv, just as described and I was able to install nmigen. Maybe an older version of venv didn't install wheel?

Either way, there is nothing in nmigen that explicitly requires wheel. If setuptools_scm is using wheel for the installation then wheel is its dependency. If wheel was an optional dependency of setuptools_scm and was required here, then it should be in setup_requires, but it isn't.

mithro · 2020-04-14T17:15:49Z

@FFY00 - Your on Arch Linux right? I think the problem is with how Ubuntu / Debianism mangles Python packages. Is wheel is an optional dependency of setuptools / pip?

FFY00 · 2020-04-14T17:21:51Z

Then it would be a Debian bug. No, wheel is not a dependency for either setuptool_scm or pip, at least in the latest versions.

The default __repr__() from typing.NamedTuple does not include the module name, so the replacement (which uses the preferred syntax for specifying these shapes) doesn't either.

alanvgreen · 2020-04-15T05:35:39Z

I am seeing the problem on Ubuntu.

Installation is successful with "wheel" in extra_requires rather than setup_requires.

One aspect of this problem is that wheel appears to be installed by default with virtualenv, but not with venv.

FFY00 · 2020-04-15T06:01:58Z

How does your setup.py look like? There's is no extra_requires, it is called extras_require and it's not a list like setup_requires.

Can you post the exact commands to reproduce?

It seems like you messed up the history by doing a merge. Can you look at reflog, do a hard reset to a previous state and then rebase on master? This should result in a clean git tree with just one commit on top of master. Let me know if you need help with the commands.

ohsix · 2020-04-15T06:12:45Z

what version of ubuntu and python3?

whitequark · 2020-04-15T06:24:22Z

@alanvgreen I believe you are hitting an issue with the way Debian ships Python packages. If you install python3-wheel from apt, do you still have this problem?

I don't know what to make of that - I wouldn't trust the installation.

Looking at https://setuptools.readthedocs.io/en/latest/setuptools.html#declaring-extras-optional-features-with-their-own-dependencies I'm not sure why extras_require is the right thing to use here. What did you have in mind?

alanvgreen · 2020-04-15T07:55:18Z

@whitequark It turns out that I already had python3-wheel installed. I can't recall whether I explicitly installed it before - it may have been a dependency of something else, but very likely it was something I tried while working through my problems.

At this stage, I'm quite happy for the resolution of this PR to be "use virtualenv, not venv" :)

whitequark · 2020-04-15T07:58:28Z

It looks like the documentation for venv describes it as deprecated since 3.6. Is that right?

programmerjake · 2020-04-15T08:07:34Z

It looks like the documentation for venv describes it as deprecated since 3.6. Is that right?

only the pyvenv script was deprecated where python -m venv is the recommended replacement:

whitequark · 2020-04-15T08:29:25Z

@alanvgreen If you're happy using virtualenv then I suggest closing this, since it seems very hard to reproduce. If someone manages to find a good solution here I'm happy to merge it as well.

@alanvgreen Thanks for confirming! There are some issues with #358 that prevent merging it in the short term, but I'll make sure that this is fixed at some point. For now, please use virtualenv.

This is necessary to be able to install nMigen into a virtualenv that does not have `wheel` installed in certain cases. See #349.
