ResourceWarning: unclosed file

[John Boyd]

Hello All,

I am a new user of Bottle and I keep getting the following error:

  sys:1: ResourceWarning: unclosed file <_io.BufferedRandom name=5>

I have a form where the client uploads an image, the image gets saved to the image folder correctly.

However when the form reloads and posted again I get the above mentioned error.

My code:

@post('/stockcount')
def database_update():
    sku = request.forms.get('sku')
    description = request.forms.get('description')

    image_folder = 'images/'
    img = request.files.get('image')
    img.save(image_folder)

    return template('views/index.tpl', form=form)

My setup is:

• Ubuntu 18.04.3 LTS
• Both Bottle.py stable AND Bottle 13-Dev ( I tried both, got same error)
• Python 3.6.8
• Virtualenv

Any help will be greatly appreciated.

Best Regards,

John.
