Make nbsmoke a bit more maintainable

Make nbsmoke a bit more maintainable by separating out the various
parts, adding a few docstrings, and improving test coverage.
Some ipython magic handling has probably changed (should be an
improvement/more consistent behavior).
This work is over a year old. I think the need to lint check notebooks
that involve a lot of magics has gone away since this work was
originally done.  However, the changes here still bring some
benefits (e.g. the modularization will also allow functionality to
be removed easily).
Details:

Separated out parts into modules:

the original/basic functionality (checking notebooks run without
errors)

"verifying" (copied from datashader, which was copied from
bokeh?)

lint/flake checking (using pyflakes)

magics handling for flakes (custom, hacky ipython magic sparsing)

Improve lint/magics debugging by storing various intermediate
files.

Simplify lint checking of magics, making behavior more consistent.

Internal refactor of magics handling, which should allow the
custom/hacky implementation here to be swapped out and/or removed
without affecting other aspects.

Improved unit test coverage (think all code is now covered except
"verify").

If the line count has gone up, it should be from docstrings and tests rather than code :)
Still to do this PR:

restore py2 support

Run the lint checking over all notebooks of the various pyviz
projects as a sanity check.

Future work:

Figure out how to measure test coverage in a way that doesn't miss
out module-level lines (module-level definitions, imports, etc are
all missed because apparently they happen before coverage
collection begins; I suspect this is something to do with my not
knowing how pytest plugins work).

Find datashader/bokeh "verify nb" unit tests and copy them in
here? (verify nb stuff is copied from datashader, which appears to
be from bokeh originally...I think the original plan was to
replace datashader/bokeh "verify nb" with nbsmoke...)

Yes, I'm also very happy for decisions to come from @jsignell. Here's my recollection/opinion for background...
We must have removed the "verify nb" code from datashader after the work for this pr was originally done, and hence that comment is out of date (in this pr, verify has just been broken out to its own file; the code is already present in current nbsmoke). I think the original source for datashader's verify was bokeh (I was not the author of any of it, and did not add it to datashader - it's likely I just wanted to remove it from datashader and have it "in one place"...of course in doing that I just ended up adding it in yet another place ;) ).
As for the magics processing for flake checking, I'd probably keep it all to start with (assuming it works!). Once there's no more hv opts magic in pyviz notebooks, then I'd happily delete the hv magics file. (Or if already at that stage, it could be deleted now.)
The rest of the magics processing contains at least some things that are useful for flake checking notebooks in general. E.g. %time f() gets flake checked as f(). So maybe decide which bits are useful, then aim later to replace (parts of) their implementation with what is available from jupyter/ipython (e.g. surely parsing can come from them...)?

Sounds good. The hv magics should all be gone already, but if we missed some, then not having support for them would be a good way to find any that are left so we can fix them!

Ok, makes sense to remove the hv magics handling in this PR then (I'll do that).

A note about the notebook flake checking in general. To give an idea of the kinds of things it finds, see e.g.
pyviz/holoviews#3550, pyviz/holoviews#2690, pyviz/holoviews#2439, pyviz/holoviews#2091.
If notebook flake checking doesn't produce false positives and is quick to run (I think both should be true...), I'd be in favor of enabling it for projects. As part of this pr I'll run flake checking over all the pyviz projects and report the results back here.

Sounds great, thanks!

I think this is all a good plan and will make it easier to maintain nbsmoke. I just wrote a sphinx time magic stripper the other day... So @ceball if you have the time to take out the holoviews magics stuff that'd be great. Let me know when you are done.

Re Python 2, I don't think it is very important at all to have nbsmoke work for it.

Re Python 2, I don't think it is very important at all to have nbsmoke work for it.

Right; we can just run smoke tests under py3; no problem.

I have not yet removed hv magics handling, but I've run this PR's nbsmoke over all pyviz projects (I think I got them all!). I'll re-run after removing hv magics handling, but a few questions have come up:

nbsmoke could easily support ipython's display() (i.e. using display without importing). Should it? (My vote: it should complain. But maybe I'd feel different if I were a heavy notebook user...)

A few pyviz notebooks use some ipython aliases, e.g. ls ./output, rm -r ./vicksburg_south. I think we agreed not to use those as they are confusing (e.g. ls is ok on win, but ls -l is not because ls actually maps to dir...). What do you think?

hvplot relies on import side effects, so there are apparently unused imports in hvplot examples. I'm opposed to imports with side effects, but I also think they are a good idea for hvplot :) What should nbsmoke do? Allow a whitelist of acceptable unused imports to be supplied? Or should the imports be explained with a #noqa comment? Any better idea?

I noticed a complaint about a __future__ import not being at the start of the file. I'm surprised to see a __future__ import in an example notebook, and I guess it could be avoided in the example here, but nbsmoke could be changed to handle __future__ imports better.

I also noticed that one or more pyviz notebook has "#noqa". I thought we weren't going to use that? Or if using, maybe it should say why, e.g. #noqa: imported for you to use in your solution?)

Output follows...
(Note: the timings are unlikely to be realistic for your hardware; they were run in the background on a win/32bit/2GB/1GHz atom laptop, which was primarily showing kids tv ;)

I have not yet removed hv magics handling, but I've run this PR's nbsmoke over all pyviz projects (I think I got them all!). I'll re-run after removing hv magics handling, but a few questions have come up:
nbsmoke could easily support ipython's display() (i.e. using display without importing). Should it? (My vote: it should complain. But maybe I'd feel different if I were a heavy notebook user...)

Thanks for this!  I personally really hate display() being in the namespace automatically, and I think people should import it.  So I think nbsmoke should keep complaining about it, particularly so that notebook code can be used in non-notebook contexts (e.g. panel serve) or at least make it more clear that it can't be. It's easy to miss a call to display().

A few pyviz notebooks use some ipython aliases, e.g. ls ./output, rm -r ./vicksburg_south. I think we agreed not to use those as they are confusing (e.g. ls is ok on win, but ls -l is not because ls actually maps to dir...). What do you think?

We agreed not to use them, but haven't removed all examples of them.  We'll need to make a PR in each case.

hvplot relies on import side effects, so there are apparently unused imports in hvplot examples. I'm opposed to imports with side effects, but I also think they are a good idea for hvplot :) What should nbsmoke do? Allow a whitelist of acceptable unused imports to be supplied? Or should the imports be explained with a #noqa comment? Any better idea?

Good question. If it's straightforward to add a user-extensible whitelist of unused (sideffecty) imports (presumably as globs hvplot.* or regexes hvplot[.].*), then that sounds cleaner than adding #noqa all over the place. But I do think it's important to check for unused imports, as we seem to leave them all over the place and they are confusing for users who will wonder what their purpose is.  So if it has to be #noqa, I think it's worth it to get checking enabled.

I noticed a complaint about a __future__ import not being at the start of the file. I'm surprised to see a __future__ import in an example notebook, and I guess it could be avoided in the example here, but nbsmoke could be changed to handle __future__ imports better.

It seems like using __future__ is an error there? Maybe the start of a notebook cell is defined as "the start of a file", but in any case such usage won't work if the file is exported to a Python script, so I think we should simply avoid using __future__ in this way.

I also noticed that one or more pyviz notebook has "#noqa". I thought we weren't going to use that? Or if using, maybe it should say why, e.g. #noqa: imported for you to use in your solution?)

For an exercise, sure; that wording sounds good.  In general, I think we should try not to have #noqa whenever possible, but I don't see how we will always avoid it.

examples/topics/batched_example/GSSHA_Workflow_Batched_Example2

Any idea if these issues are real ("invalid escape sequence")?

Chris, thanks so much for running it on all those projects! It is abundantly clear which ones have linting enabled in CI and which don't...
For display I think making people import it is a good idea. I know I was very confused the first time I saw a reference to it in a notebook and couldn't find the import.
Yep I agree. I actually think #noqa with an explanation for hvplot imports isn't such a terrible idea. It makes it clear what is going on and these are all examples so they should be explicit.
I've been seeing the escape sequence warning cropping up in various places, but hadn't looked into it yet.

About the invalid escape sequence warnings: their appearance is probably down to whatever warning filter is used by pytest, but it's not an nbsmoke or a pytest thing:
> set PYTHONWARNINGS=default

>type esc.py
"\z"

>python esc.py
esc.py:1: DeprecationWarning: invalid escape sequence \z
  "\z"

>type esc2.py
r"\z"

>python esc2.py

> python --version
Python 3.6.8

Changed in version 3.6: Unrecognized escape sequences produce a DeprecationWarning. In some future version of Python they will be a SyntaxError.

https://docs.python.org/3/reference/lexical_analysis.html

Ok, sounds like those warnings are real and we should be adding escape characters to the strings in those notebooks. Thanks.
I'm happy with either the whitelist or the #noqa approach for hvplot; I'll leave that up to you two.

I've fixed the flake checking under python 2 for the benefit of charities etc that can't afford to upgrade from python 2. Still got the appveyor/windows tests to fix (I'm using windows locally, so surprised they don't just pass..). Also still got the conda tests to fix (I can't run conda locally - laptop too slow :( - but I should be able to figure it out from the travis logs later).

Finally, the travis tests are passing.
When you run nbsmoke's tests with current versions of jupyter ecosystem packages, you get quite a few deprecation warnings (e.g. from how nbconvert uses ipython and traitlets). nbsmoke's tests are counting/checking warnings during the tests, to ensure warnings are not being generated or are being generated appropriately for each test. I want to filter out the deprecation warnings (i.e. completely ignore them), but the only way I've found to do that is by setting the PYTHONWARNINGS environment variable. Setting pytest's own warnings filter results in some (though not all) deprecation warnings still appearing. I suppose I could modify nbsmoke's warning checking to filter out deprecation warnings, but that looks a bit tricky to do (maybe if I knew pytest better it would be easy?). Requiring an environment variable to be set for the tests to pass is a bit annoying for nbsmoke developers, nbsmoke packagers, and users of nbsmoke who want to run its self tests after installing.
Anyway, for the python/pip tests, I set PYTHONWARNINGS in tox.ini, and that seems ok: even though it's annoying to have to set an environment variable, at least doing it there will mean it happens for anyone running the tests via tox.
However, I don't know how to do the same for conda. In the end, I set PYTHONWARNINGS on travis and then instructed conda build to pass that through. Maybe there's a better way?

Good question. I don't know of one.

I jsut opened #21, #22, #23, #24, and #25 - happy to get comments on any of them (even if it's just "I don't understand the point" :) ).
I'll do #23 as part of this PR because I have looked at the code recently and only involves nbsmoke itself (not e.g. pytest) so it will be easy. And I'll remove the hv opts handling plus fix the appveyor tests. At that point, I think it should leave something that will work as desired for current pyviz projects as they are now (having to use noqa for hvplot, though) - I'll verify that by running over all pyviz projects again.

I've removed the need to set the PYTHONWARNINGS environment variable.
(Testing plugins is a bit different from normal testing; I've now re-learned what I apparantly used to know when I initially created the tests: https://docs.pytest.org/en/latest/writing_plugins.html#testing-plugins. I realized that options passed into pytest at the top level weren't applied where needed, because the tests are running pytest themselves (since nbsmoke is a pytest plugin). The problem was that each test's "parseoutcomes()" was picking up warnings which the "top level" pytest was set to ignore.)

I guess the appveyor tests have been lost in one of the pyviz renames? :(

Running again over some of our projects...

I guess the appveyor tests have been lost in one of the pyviz renames? :( Although I am developing on win, the appveyor tests were failing when I last worked on this PR.

Hmm yeah I can look into that. I'm a little surprised they are failing since you are the only one who's been making changes...

I remember I was also surprised to find appveyor was failing for this PR since I was developing on windows, but it was definitely failing.
I recall now I could not immediately figure out why it was failing. That's part of the reason this PR stalled before. Maybe I should get it in before you restore appveyor? :)

That is fine by me :) We don't need it to run on windows.

@jsignell I'm sure I'd like to improve the code, but it would also be good to start trying to use this version before another couple of years go by ;) So I'll happily fix or clarify stuff in response to any comments you make, but otherwise I'm done with this PR.

@jsignell, thanks for taking the time to review! Can't have been pleasant ;)
Let me know if I missed anything.
