Playing with `on_device_unit_test_app` #2046 - Episode II by opacam · Pull Request #2088 · kivy/python-for-android

opacam · 2020-03-17T21:54:34Z

This is not to be reviewed nor merged, of course commented if you want, but the purpose of this is to play a little more with some new recipes and the on_device_unit_test_app (#2046)...so I understand this as some kind of continuation of #2076 (just to have a new start point with the current develop branch).

I'm not sure if we have to include all the changes I advance to you in here, but sure that there are some new recipes that can be very useful. I made this to make it work mplfinance, a kind of matplotlib's extension. To do so I faced several issues along the way, which forced me to introduce a couple of libraries that will allow us to build some python compiled modules that currently aren't compiled: _bz2.cpython-38.so and _lzma.cpython-38.so. Also I was forced to create a Pandas recipe...this one is interesting right?

Anyway, If you guys find this interesting, I will create separate PRs...so give me your thoughts about this:

should we include libraries: bz2 and lzma?
should we enable the built of some extra python modules: _bz2.cpython-38.so and _lzma.cpython-38.so (depends on previous steps)?
should we add a pandas recipe (depends on previous steps)?
should we introduce mplfinance recipe (again...depends on previous steps)?

I think that the first three points are worth it...the last one probably too (it doesn't seem hard to maintain).

So depending on the supplied recipes, a different test app will be ran. The supported test apps are: - kivy - flask - no-gui

for our CI providers and `rebuild_updated_recipes.py` because we recently removed the old test app that we made use of.

Remove sentence regarding python2 compatibility... because python2 it's almost at the end of his life

So we can get an apk via gh-actions Notes: - this way the reviewers can install the flask apk without making the build - these changes will be reverted in the next commit...since we want a kivy app as our default)

This reverts commit 0ed4d70.

in case that we detect that p4a will build an `service_only` app. Note: if we don't do this we wil get errors once we try to create our apk with the target distribution

and: - remove Python 2 test apps because: + we already test Python 2 with travis + Python 2 it's almost at the end of his life - change gh-actions job title (because it looks better)

Because it looks better and is more readable.

Because reducing filename to `setup.py` will make our cli arguments shorter and source code cleaner

So our matrix gh-actions builds will not be cancelled if some arch fails which is very useful to fix specific arch issues. See also: kivy#2073

Fix our `CI` travis tests by explicitly omit the numpy build for MacOsX. Yeah...not actually a solution for MacOsX...but at least we will have the `green tick mark` for our `CI` tests...but we have a problem with MacOsX and numpy recipe :< See also: kivy#2073

To fix travis CI tests when trying to build `liblzma` recipe

Because it causes an error when running from `CI`

Even though the PR is too big to my personal taste, this is some pretty impressive work again 👏
Since it's very big we may overlook a lot of things, but I'm OK to take the risk given the improvements it provides.
I wrote some minor comments, but nothing blocking from my point of view.
Thanks for your time and efforts ❤️

Typically this recipe as well as pandas could have been added in another dedicated PR, right?
This two recipe alone are simple enough to review, but in general if should try to reduce huge PR when possible to reviewers don't get scared/discouraged by the size of it or lose focus during the review. Also if large PR receive a lot of comments then the contributor might as well get discouraged or simply side tracked and drop it.
By the way line one is empty 😄

Since I'm a little late, what's the status of this, does anything still need comments?

opacam · 2020-03-31T19:02:45Z

Actually we can close this because this was only a draft and, the important stuff, we have it already merged in separate PRs, anyhow...there maybe some interesting tests for the on_device_unit_tests and one recipe for mplfinance, but not to be done here...so closing this and...
¡¡thanks to be here guys!!
