Fixed #25121 -- Added a warning that filtering sensitive information from error reporting isn't bulletproof

This is consistent with Python's official documentation
and it's a sphinx recommendation too[1].

[1] http://sphinx-doc.org/markup/desc.html#dir-method

Refs #21855.

Sphinx generates left single quotes for apostrophes after
code markup, when right single quotes are required. The
easiest way to fix this is just by inserting the unicode
character for a right single quote.

Instances of the problem were found by looking for
">‘" in the generated HTML.

Thanks Ram Rachum for the report and the initial patch, and Simon
Charette for the review.

    Tweaked default settings file.

    * Explained why BASE_DIR exists.
    * Added a link to the database configuration options, and put it in its
      own section.
    * Moved sensitive settings that must be changed for production at the
      top.

    Adjusted the default URLconf detection to account for the admin.

    It's now enabled by default.

    Added security warnings for the most sensitive settings.

Date:   Mon Jan 28 23:24:06 2013 +0100

    Used an absolute path for the SQLite database.

    This ensures the settings file works regardless of which directory
    django-admin.py / manage.py is invoked from.

    BASE_DIR got a +1 from a BDFL and another core dev. It doesn't involve
    the concept of a "Django project"; it's just a convenient way to express
    relative paths within the source code repository for non-Python files.

    Thanks Jacob Kaplan-Moss for the suggestion.

    Removed STATIC_ROOT from the default settings template.

    It isn't necessary in development, and it confuses beginners to no end.

    Thanks Carl Meyer for the suggestion.

    Removed MEDIA_ROOT/URL from default settings template.

    Many sites will never deal with user-uploaded files, and MEDIA_ROOT is
    complicated to explain.

    Thanks Carl Meyer for the suggestion.

    Removed logging config.

    This configuration is applied regardless of the value of LOGGING;
    duplicating it in LOGGING is confusing.

    Enabled the locale middleware by default.

    USE_I18N is True by default, and doesn't work well without
    LocaleMiddleware.

    Avoided misleading TEMPLATE_DEBUG = DEBUG.

    According to the docs TEMPLATE_DEBUG works only when DEBUG = True.

    Removed STATICFILES_FINDERS/TEMPLATE_LOADERS from default settings file.

    Only developers with special needs ever need to change these settings.

    Removed STATICFILES/TEMPLATES_DIRS from default settings file.

    The current best practice is to put static files and templates in
    applications, for easier testing and deployment.

    Removed settings related to email reporting from default settings file.

    While handy for small scale projects, it isn't exactly a best practice.

    Normalized the default application template.

    Removed the default test that 1 + 1 = 2, because it's been committed
    way too many times, in too many projects.

    Added an import of `render` for views, because the first view will
    often be:

    def home(request):
        return render(request, "mysite/home.html")

Fixed #19453 -- Ensured that the decorated function's arguments are obfuscated in the @sensitive_variables decorator's frame, in case the variables associated with those arguments were meant to be obfuscated from the decorated function's frame.
Thanks to vzima for the report.

This adds a flexible mechanism for filtering what request/traceback
information is shown in 500 error emails and logs. It also applies
screening to some views known to be sensitive e.g. views that handle
passwords.

Thanks to oaylanc for the report and many thanks to Julien Phalip for the
patch and the rest of the work on this.

Thanks to aaugustin for implementing this.

(Technically this doesn't fix the original report, as we've decided against
having *any* default values, but the new feature makes it possible, and the
docs have an example addressing #15954).

git-svn-id: http://code.djangoproject.com/svn/django/trunk@15968 bcc190cf-cafb-0310-a4f2-bffc1f526a37

Changed e-mail to email throughout documentation and codebase. The one exception is translation strings, which I didn't want to disrupt
