python-for-android recipe tests

[inclement]

As far as I'm concerned, the core recipes that need testing are:

• python2
• python3crystax
• openssl
• sqlite
• numpy
• pyjnius
• kivy
• setuptools
• sdl2
• kivent
• ffpyplayer
• android
• plyer

This is the core set that I try to make sure will always build, and which are (I think) the most commonly used by p4a projects. They're probably the ones that need testing the most. All of these should be compatible except python2 with python3crystax, and openssl with python3crystax.

That said, I haven't put much deep thought into this, I'm happy to consider other recipes equally important if people suggest them.

No, of all of these kivent is the one I haven't actually tried for a long time, I mostly rely on kovak to maintain it. Adding it to the tests would go some way to avoiding the accumulation of problems, though.

Edit: This was a reply to a deleted post asking about kivent.

Great looks good for a start. I think introducing them in the current .travis.yml should be fairly, even though I know some may already fail.
However at the end the .travis.yml file will look ugly. I already don't like the long lines that we have. So I'm trying to think of another approche, like a side helper script or a Makefile. I'm not too sure.
Or we could start simple and just add more "ugly" long lines and see later for a refactoring.
How do you guys see this?

[inclement]

@AndreMiras p4a has a couple of ways to set command line arguments via files, which I guess should be sufficient to solve that problem.

[AndreMiras]

Thank you @inclement for the suggestion, I like the approach and I've implemented it in a first pull request #1277.
Please don't close the ticket once it's merged because it doesn't tackle all recipes, but only sdl2,pyjnius,kivy,python2 which is already a good start :)

Agrr I wanted to take a look at setup_testapp_python2_sqlite_openssl.py, but peewee is causing nested virtualenv issues.

[ERROR]:   virtualenv is needed to install pure-Python modules, but
[ERROR]:   virtualenv does not support nesting, and you are running
[ERROR]:   python-for-android in one. Please run p4a outside of a
[ERROR]:   virtualenv instead.

This is annoying, because this setup has a lot of interesting recipes to test, such as openssl and sqlite3. And also even though it would be easily achievable to run outside a virtualenv, I don't really like it because we loose the isolation and rely on system modules. So I'm not too sure about it, what would you guys suggest. I currently see two ways:

1. create another setup_testapp_python2_sqlite_openssl.py and testapp_sqlite_openssl/main.py with no peewee dep
2. go without a virtualenv at all 😢

What do you guys think?

[inclement]

The ideal solution would be to make p4a work inside a virtualenv. The reason it doesn't is only the single very specific way it installs pure-python packages, by making a new virtualenv. I'm sure there must be a compatible way to do it, but haven't ever looked at it much.

While I understand the value of virtualenvs, p4a isn't very picky about its dependencies, and I don't usually worry about just running it outside of any.

As far as testing the build goes, though, removing the peewee dependency would be fine (maybe you can even do it inline without a new file by adding --requirements=sdl2,pyjnius,kivy,python2,openssl,sqlite3, which I think will override the previous requirements entirely).

[AndreMiras]

Thank you very much for your feedback. I can give a try to the inline version, even though we loose a bit of setup interest.

[AndreMiras]

I've implemented what you suggested overriding peewee in #1278
So now with this second pull request we have more recipes covered, new status would be.

I was under the impression that virtualenv is pretty much obsolete in the face of conda (I work in bioinformatics)...

P.S. I made a comment in this thread earlier about a different topic, but as it seems this is an active thread -- Does anyone have a working Kivent recipe for kivy-ios?

I posted a $25 bounty on this last week:
https://www.bountysource.com/issues/58415450-kivent_core-recipe

[AndreMiras]

@LarsDu thanks for sharing about conda, yes it may be worth investigating in that direction too, but let's not hijack this topic.
Feel free to open a dedicated issue or even come with a pull request.
Regarding the other topic (kivy-ios), well it's another topic, right?
To be honest I would love to help, but I only have Linux computers, so unless I can do it through cross-compiling on my Linux box, I don't think it's going to happen.
Last thing, looking at the kivy-ios repo, I'm surprised to see we duplicate so much code from p4a I would have expected that we at least inherit and specialize.
But let's not discuss all of that in this topic.

[AndreMiras]

Pull request #1281 is green! It builds python3crystax with the following other requirements: sdl2,pyjnius,kivy.
New covered recipe list is:
💚 [DONE] python2
💚 [DONE] python3crystax
💚 [DONE] openssl
💚 [DONE] sqlite
🔶 [TODO] numpy
💚 [DONE] pyjnius
💚 [DONE] kivy
🔶 [TODO] setuptools
💚 [DONE] sdl2
🔶 [TODO] kivent
🔶 [TODO] ffpyplayer
🔶 [TODO] android
🔶 [TODO] plyer

We are getting there! Adding the missing pieces should be fairly easy since I think all dependencies are here. However I may take a little break now :D
Before adding new recipes, I'd like to see if we can tackle #1280, but I don't want to make the .travis.yml file unreadable.

[AndreMiras]

Another pull request #1282 that covers setuptools and android recipes, plus bonus point fixes python3crystax hostpython.
New status:
💚 [DONE] python2
💚 [DONE] python3crystax
💚 [DONE] openssl
💚 [DONE] sqlite
🔶 [TODO] numpy
💚 [DONE] pyjnius
💚 [DONE] kivy
💚 [DONE] setuptools
💚 [DONE] sdl2
🔶 [TODO] kivent
🔶 [TODO] ffpyplayer
💚 [DONE] android
🔶 [TODO] plyer

[AndreMiras]

New pull request that adds numpy (for Python 2) #1304
After the merge new status would be:

💚 [DONE] python2
💚 [DONE] python3crystax
💚 [DONE] openssl
💚 [DONE] sqlite
💚 [DONE] numpy
💚 [DONE] pyjnius
💚 [DONE] kivy
💚 [DONE] setuptools
💚 [DONE] sdl2
🔶 [TODO] kivent
🔶 [TODO] ffpyplayer
💚 [DONE] android
🔶 [TODO] plyer

[inclement]

I'm closing this as complete in principle. Although kivent is unfortunately not working, it also is not currently active so not a priority. ffpyplayer would be nice to test better but it's okay as it stands. plyer is similar. The core goal of this issue is certainly fulfilled.

Thanks to @AndreMiras :)
