here are my thoughts on what the perfect codegolf site would look like (with the potential to expand to other sorts of competitive programming): pastebin.com/raw/G5rhFrhw

of course, it's possible/probable that not everyone will agree with me, but I'm willing to discuss my reasons for the decisions

right

strangely enough, the "tags for everything" model is mostly inspired by things like Stack Exchange's close votes

and red flags

but I thought I'd put all the suggestions out there; quite probably other people will be able to improve them

symbolic privileges might be a good idea

you could do it like free to play computer games and let people put their username in a fancier font

apparently people pay real money for that sort of privilege on some sites

I just had this idea: When you edit a challenge, you can mark your edit as potentially breaking existing answers, making existing answers suboptimal, or both. That way, the poster of every existing answer gets a notification that they might consider revising their answer, and the answers can get a mark saying that they were posted before a rules revision with a link to the last version before the breaking change.

editing and closing can't safely be awarded by reputation on PPCG; maybe they could be but the thresholds are wrong, it's easy to gain access to them before you know what you do

@Pavel I like that, but in my construction, the challenge is split into two parts (the program that determines validity of answers, and the notes that give the specification in natural language); the first part can't be edited, the second part can be edited freely (and obviously doesn't change validity)

we could do that for challenges where we don't have a machine-readable validity criterion, I guess

right

in my account deletion message to SE, I explained how I once repcapped for an entire week through choice, then stopped because it wasn't very fun and was probably reducing the average quality of the site

the rep cap is a bandaid over the reputation system not being balanced at all

@ais523 I don't particularly like that automated validity testing scheme, what if I want to answer in SmileBASIC (which only works on the Nintendo 3DS)?

there are already reasons why an answer might not be testable automatically, so I assume you could use a tag for "test manually" and have people vote the answer as incorrect if it's wrong

I'd like to avoid that as much as possible though because it makes a golfing site much less usable

and if you submit a SmileBASIC answer and it's wrong, there's a decent chance nobody will ever find out :-P

@Mego IDK, a huge part of the PPCG culture is in designing and using programming languages.

I'm envisioning that the site has a list of languages but it's easy to add to

(it's pretty easy to add languages to TIO at the moment, for example)

@Mego There are some rather popular languages that don't work on TIO, Batch, Swift, Hack.

BlitzBasic, B

Just of the ones that I've personally asked Dennis to add

@Mego Wine doesn't work on TIO, we'd have to write support for that ourselves. And it's been on Dennis' to-do list for a while now

huh, why doesn't Swift work on TIO? I thought it had a Linux version, maybe not?

yep, there's an official Linux version

@ais523 It's probably because building it causes TIO to run out of memory, since that's the number one cause of languages not working on TIO, but I'll check.

fair enough

I seem to remember a similar issue with Incident

(the dependencies it needed weren't in the repos but were in Ubuntu's)

although that got fixed in the end by simply copying the source code of the dependency

@Mego At the same time, outdated software.

Like Python 35

So we'll probably be building Python 37 from source

Debian unstable might be a good tradeoff for something like this

most of the same packages as Ubuntu, but with no restrictions on how quickly they can be updated

@Mego Why not Python 37

@Mego do you have this issue locally or only on your server?

I can't reproduce it

@Mego btw what is the error message python is outputting?

@Mego 3.7.0a2 > 3.6.2

Stable software is for wimps

@Mego do you have nodejs installed? Is the command node or nodejs

@Mego Wat

Since when is it not node

@Mego aha yeah, ubuntu does that

for now you can symlink

but I'll push a fix

yay! :D

:( viewing post causes 500

but still yay :D

Sign in

Nothing works but it looks beautiful

oh, for google api key you need to add the IP+port in dev portal

actually light blue looks good

can you give a screenshot of the portal page, it still complains that the IP is not a authorized JS origin

weeiiirdd

maybe caching

:| apparently google doesn't support numerical IP

brb trying solution

can you try to add http://codegolf.vihan.org:5000 as an authorized origin

:O auth worked

I suppose I'll try to see why celery is 500ing

oh huh

huh, that is generally caused by node.js process crashing but weirdly I see no STDERR

oh, celery might be hiding it

not sure how to do this, but we might want to check if stdout is open/proc has not exited so we can restart if needed

@Mego why was from app.server import server changed to import app.server?

oh ok

@Mego can I add server = app.server.server to the start.py then. Flask debug needs it

I am going to work on adding unit tests

First time doing python unit tests so I'll add a few and we can see if I am doing correctly

not sure on optimal structuring though

Are all test files run independently?

weird, from the tests/ dir, Flask cannot be imported:

ImportError: Failed to import test module: flask.test_static
Traceback (most recent call last):
  File "/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/unittest/loader.py", line 428, in _find_test_path

    __import__(name)
  File "/Users/vihan/Documents/Code/PPCG-v2/tests/flask/test_static.py", line 1, in <module>

there is no file named Flask for there to be be naming conflict

travis-ci.org/Mego/PPCG-v2#L901

ok >_< yeah I have a dir

I am blind goat apparently

:D unit test is working

can I do this:

class TestUserSession(TestBase.TestFlask):
    def setUp(self):
        super().setUp()

like is the super() part correct

not sure how to test front-end

hm, problem: travis does not have a config.py

we can use travis private env vars for things like google api key I guess but I don't have that so I'll leave that empty

@Mego two PRs: unit tests and js tweak

@Mego what uses the create_user celery task

I get celery.backends.base.NotRegistered, with @celery_app.task idk why

everything I run from the celery CLI just hangs, not sure how to fix

the app isn't running

The full contents of the message body was:

huh

no clue on how to test though

> celery_app.tasks.register(init_celery)

> celery.backends.base.NotRegistered

water u doin celery

@Mego why does the init code need to be in a celery_app.task if it should be run w/ default event loop

:D

keeps 500ing for me

does node emit any errors?

that happens when node crashes

@Mego even in the celery log files?

could you maybe push to GH and I can see if node is doing any error

> AttributeError: module 'celery_server' has no attribute 'celery'

weird

trace not helpful either

hm, looks like I needed to add celery = app.helpers.tasks.celery_app to celery_server.py to silence error

came from running celery multi start w1 -A celery_server

weird, I still get celery.backends.base.NotRegistered: 'app.helpers.tasks.render_markdown'

maybe I should restart celery

@Mego oohhhhh

restarting celery and still gives the: AttributeError: module 'celery_server' has no attribute 'celery' error

:OOOO :DDDD rendering worked! hooray!

I just hope node.js doesn't die on larger posts

@Mego does server.py still need the import app.helpers.tasks

@Mego btw PR: github.com/Mego/PPCG-v2/pull/32 (also I think the celery PR #31 is ready to merge now)

no worked fine

should I change unit tests PR to merge into celery PR

am I not doing multiple inehritance right:?

class TestUserAPI(TestBase.TestFlask, TestBase.TestDB):
    def setUp(self):
        super().setUp()

it's not calling TestBase.TestDB 's setUp

oh

brb downvoting misleading SO post

I addeD:

class TestUserAPI(TestBase.TestFlask, TestBase.TestDB):
    def setUp(self):
        super(TestBase.TestFlask, self).setUp()
        super(TestBase.TestDB, self).setUp()

where:

class TestBase:
    class TestFlask(unittest.TestCase):
        def setUp(self):
            self.app = server.test_client()
            self.app.testing = True

and then the next call says self.app does not exist

the above is correct, no?

aha

should I use url_for in the tests or just directly enter URL

@Mego is it OK if I merge the tests branch?

@Mego Appears that the static/lib folder has been cached. Remove it and the JS will be re-compiled

yeah

try rm -r static/lib static/css static/.webassets-cache to clear all the caches

oh you need to npm install to install some new modules

run above in project root dir

there we go :D
