python3Packages.dash: init at 1.8.0 #77837

antoinerg · 2020-01-16T17:50:30Z

Motivation for this change

Dash is an open-source framework that creates analytical web apps from Python without writing a single line of javascript (https://dash.plot.ly/). It would be awesome to package it in NixOS!

Things done

Manual test

I tested that I could start a simple Dash app:

$ nix-shell -I nixpkgs=$(pwd) -p python3Packages.dash
$ python app.py

nix-review pr passes on macOS.

jonringer

there should roughly be a commit per package addition

jonringer · 2020-01-16T23:11:13Z

pkgs/development/python-modules/dash-core-components/default.nix

+  pname = "dash-core-components";
+  version = "1.7.0";
+
+  src = fetchurl {


There's already a helper for this, see https://github.com/NixOS/nixpkgs/blob/211ed174657712a00fd3bcabd590d2e7b7a25e10/pkgs/development/python-modules/requests/default.nix for an example

Suggested change

src = fetchurl {

src = fetchPypi {

@jonringer I initially gave up on fetchPypi because it wasn't working for me. I just realized it's because the package name should have underscores instead of dashes. It's now fixed for all packages in 4f0952022dcd5314aa6b56a98901155110c3294a.

~~@jonringer I'm sorry, I wasn't aware of that. Can I rebase and force push with a proper commit log?~~ Ok so I force pushed a cleaned up commit log to fit that requirement.

jonringer

Please add tests (checkout from the github repos is preferable to no tets)
Please add yourself as a maintainer
Please apply comments to all packages

closes #69110

+    description = "Dash is a Python framework for building analytical web applications. No JavaScript required.";


don't need to define the subject, we know it's the description of a given package. "No JavaScript required." is just click-baity

Suggested change

description = "Dash is a Python framework for building analytical web applications. No JavaScript required.";

description = "Python framework for building analytical web applications";

Fixed in 411a351

needs other suggestion to work

Suggested change

license = with lib.licenses; [ mit ];

Done in 411a351

Thanks! Done in 411a351

Please add tests (checkout from the github repos is preferable to no tets)

I am sorry to be such a newbie but can you expand on this @jonringer? Would the following be enough?

  # in lieu of proper tests
  pythonImportsCheck = [
    "dash"
  ];

Thank you for your patience

jonringer · 2020-01-17T21:44:08Z

pythonImportsCheck will essentially do python -c 'import $MODULE_PATH' for each item. This will catch stuff such as namespace issues or some missing dependency issues. It's to give a little more validity that the package would be able to work in a normal workflow.

EDIT: However, unit tests are a much better measure to ensure the packages are internally correct and usable.

So I take it it would be good enough?

jonringer · 2020-01-17T21:45:58Z

I am sorry to be such a newbie

I was a newbie at nix not too long ago as well. No reason to apologize :)

jonringer · 2020-01-17T21:48:43Z

The big push for tests is to ensure that a bunch of packages aren't subtly broken. Since the sources are available through github, it's preferred to use from source rather just have our fingers crossed.

This becomes more important when we have to alter upstream version bounds, having tests ensures that we have valid packages, even if upstream isn't testing against those dependency ranges.

jonringer

for the add antoinerg as maintainer of python3Packages.dash-* commit, do you mind just doing:

  antoinerg = {
    email = "roygobeil.antoine@gmail.com";
    github = "antoinerg";
    githubId = 301546;
    name = "Antoine Roy-Gobeil";
  };

as maintainers: add antoinerg

then adding yourself to the other packages can remain as another commit.

Generally maintainer additions are separate from package changes.

Not sure how strong your git-fu is, let me know if you need help with altering git history. (but i would look at how to use git rebase -i if you're not already familiar)

antoinerg · 2020-01-20T16:03:14Z

EDIT: However, unit tests are a much better measure to ensure the packages are internally correct and usable.

With 9cd2e23, it now runs a few unit tests. I skipped the ones that require browsers. All those tests are run upstream prior to a release. I hope this is good enough @jonringer !

jonringer · 2020-01-21T02:20:51Z

please squash the dash fixup commit into the other.

git rebase -i HEAD~4
# move `python3Packages.dash: pull from github instead of pypi, run unit tests` line below dash init commit
# make `pick -> squash` for python3Packages.dash: pull from github instead of pypi, run unit tests
# save

git push --force

otherwise LGTM
