Problem:

• GIFs in current Readme(https://github.com/ethanchewy/PythonBuddy/blob/master/README.md) show the earliest version of PythonBuddy.

Goal:

• Produce GIFs of the most current version of PythonBuddy and update them in the Readme

How to do this?

• Follow Readme instructions on installing
• Check out what GIFs are currently displayed in README and take videos of exactly the same functions but wiht updated PythonBuddy
• Load up PythonBuddy in local browser and take screenvideos of site.
• Convert those clips to GIFs and update readme

Describe the bug When I start the app, my first test was click on Run button and I've received KeyError: 'file_name'. Before run the app, i've needed to update werkzeug to the last version cuz with the version in requirements.txt the app cannot be run

To Reproduce Steps to reproduce the behavior:

1. start application with Flask run (werkzeug updated)
2. Click on Run button
3. open your terminal
4. See error

Screenshots

Desktop (please complete the following information):

• OS: Ubuntu 20 // windows 10
• Browser Firefox

Additional context It happens on my Windows PC and Ubuntu too.

Hi, Ethan ✌ I just set PythonBuddy in my WSL installation and during the installation of the required packages an error was raised. I was able to fix it so I'm posting the step here in case anyone is interested.

Steps to reproduce the behavior:

1. Ubuntu 20.04 on Windows Subsystem for Linux
2. Python 3.8
3. Clone the repo, create a virtualenv for it
4. Try to install the required packages and get the following error:

    Running setup.py install for typed-ast ... error
    ERROR: Command errored out with exit status 1:
     command: /usr/bin/python3 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-tr7ufsax/typed-ast/setup.py'"'"'; __file__='"'"'/tmp/pip-install-tr7ufsax/typed-ast/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /tmp/pip-record-qwpgruzh/install-record.txt --single-version-externally-managed --user --prefix= --compile --install-headers /home/marcelo/.local/include/python3.8/typed-ast

Expected behavior ´´pip3 install -r should execute without errors´´

I managed to fix this by upgrading the version of the package that is being accused of raising the error. Someone at Stackoverflow had a similar issue and the solution worked for me here too. Solution:

Upgrading to typed-ast==1.4.1 worked for me using Python 3.8.5

After the solution was applied I could install the required packages without errors.

Here's the branch that needs to be fixed: https://github.com/ethanchewy/PythonBuddy/tree/restrictedpython

Error is pretty simple. The code runs fine and is linted. The line numbers just have to be adjusted correctly. Right now, it displays negative line numbers

Seems like windows and Linux has different error formats, so Linux has line number on position [1] and Windows on position [2] (when you split string by ":")

Adds setup in .travis.yml to run coverage in travis and report coverage to coveralls.io

Just exactly what I need. Thank you so much for all of the hard work.

Forgive me if I make one comment. There are really two parts to this. One is the core server functionality. And the other is the flask app which calls it.

For those of us who are not using Flask, it would be nice if they were in separate files. Then I would not have to import all of flask to use it.

Otherwise, it looks like lots of hard work has been done by EthanChewy.
Thank you so much.

For example two, the example code is:

methods = []
for i in range(10):
    methodds.append(lambda x: x + i)
print methods[0](10)

Could you change it to this:

methods = []
for i in range(10):
    methods.append(lambda x: x + i)
print methods[0](10)

Ideas for achieving this:

• Using Restricted Python. Check out my branch over here: https://github.com/ethanchewy/PythonBuddy/tree/restrictedpython I basically finished it's implementation. I want to make it a little bit more flexible. The only bug over there is the line number that is being displayed.
• Process it using PyPy sandbox: http://doc.pypy.org/en/latest/sandbox.html .

Resources:

• The failure of pysandbox
• Building and breaking a Python sandbox
• StackOverflow

Other Implementations of Python Sandboxes to look at:

• edX's CodeJail
• PythonTutor Simple Sandbox

Line Numbers do not show up correctly when PythonBuddy is running on a Windows system.

Thank you @DirtySoc for raising this up and providing these screenshots: Windows 10 1803 w/ Python3.7:

Ubuntu 18.01 w/ Python3.6.6:

PythonBuddy was developed for Unix systems so it works on Mac and Ubuntu for example. Unfortunately, the line numbers are not processed correctly in PythonBuddy for Windows. My hunch is that in app.py the data passed in the AJAX calls is formatted differently in Windows systems. Or, there is an issue with creating temp files in Windows system.

If the code is longer than the server specified allowed request limit (seemingly 8KB) a HTTP 414 error is returned. This is because HTTP GET is used, and can easily be fixed by using HTTP POST.

E.g. replacing in javascript.js: https://github.com/ethanchewy/PythonBuddy/blob/895ecbcbbe4e7053913af4b60365cf1c3c31f7b1/static/js/javascript.js#L88-L95

With this:

$.post('/check_code', {
    text :  code
}, function(data) {
    current_text = data;
    //Check Text
    check(current_text);
    return false;
}, 'json');

If this limit is intentional, then there are still better ways to handle it than just "crashing". E.g. just checking the length of the string to be sent to the server beforehand, and telling the user that is the case.

Hello 👋

I run a security community that finds and fixes vulnerabilities in OSS. A researcher (@evanottinger) has found a potential issue, which I would be eager to share with you.

Could you add a SECURITY.md file with an e-mail address for me to send further details to? GitHub recommends a security policy to ensure issues are responsibly disclosed, and it would help direct researchers in the future.

Looking forward to hearing from you 👍

Is your feature request related to a problem? Please describe. For easy usage to users, we can deploy it on vercel @vercel

Describe the solution you'd like Using this: https://vercel.com/docs/runtimes#official-runtimes/python

Describe alternatives you've considered Heroku Can be used, but it is difficult to configure. Also, its response time is slower in some regions.

As a user, I want to be able to view my previous code submissions.

Since PythonBuddy is only for 1 user for this repo (for PythonBuddySandboxed aka the demo server, it's different), we can achieve this by either

1. creating a database and storing each of the submissions. OR
2. using window.localstorage https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage

PyOdide is cPython compiled to WebAssembly and running in the browser.

If PyLint is pure python, it is quite easy to run it on top of Pyodide, in the browser. If PyLint includes C code, it is not that hard to port it to Pyodide. There is a well developed tool chain.

Then Python Buddy could run entirely in the browser. No server would be required. I would use it in the ForestWiki.com

I hope that helps. Christopher Lozinski PythonLinks.com
